-## Exact Cross-Harness Fleet Communications Contract (#766)
-
-### Problem and objective
-
-Fleet runtime contracts currently combine exact peer rows with generic operational metavariables and
-independently parsed roster data. Non-Claude harnesses can mistake those metavariables for values to
-infer, producing incorrect host, session, socket, or helper targets. The objective is one
-roster-resolved communications contract that every supported harness receives unchanged.
-
-### Normative requirements
-
-1. `FCOM-REQ-01`: Fleet commands and runtime composition SHALL use one shared v1 roster structural
-   resolver. A second lenient communications parser is forbidden.
-2. `FCOM-REQ-02`: The composed contract SHALL render the local roster member's authoritative host,
-   exact agent/session name, resolved tmux socket, exact helper path, and deterministic communications
-   generation.
-3. `FCOM-REQ-03`: Every known peer SHALL have one exact executable command. Same-host commands SHALL
-   omit `-H`; cross-host commands SHALL use only that peer's explicit roster `ssh` target; the one
-   supported fleet-wide named socket SHALL use `-L` with its exact value. A per-agent socket declaration
-   must equal that fleet-wide value; unsupported independent sockets and missing cross-host SSH data SHALL
-   fail closed.
-4. `FCOM-REQ-04`: Operational fleet examples SHALL not contain unresolved host, session, socket, or
-   helper-path metavariables. Agents SHALL select an exact rendered peer row and SHALL NOT infer,
-   substitute, or fuzzy-match targeting values.
-5. `FCOM-REQ-05`: An unknown local member or requested peer SHALL fail closed with exact-name discovery
-   guidance. Runtime composition SHALL not silently omit a requested fleet member's communications
-   contract.
-6. `FCOM-REQ-06`: Claude Code, Codex, OpenCode, and Pi SHALL receive equivalent authoritative
-   communications data through the common runtime composer.
-7. `FCOM-REQ-07`: Tests SHALL prove the contract from framework-source `TOOLS.md`, through a fresh
-   installed `TOOLS.md`, to final runtime composition and helper executability. User-owned installed
-   `TOOLS.md` content SHALL remain preserved.
-8. `FCOM-REQ-08`: Stale installed or active composed context SHALL be reported with deterministic
-   generation/repair/relaunch guidance. Currency requires the expected source and installed contract
-   marker/version plus bounded byte equality. The supported current-version repair SHALL run independently
-   of package updates, preserve divergent `TOOLS.md` bytes in a digest-qualified no-clobber backup, restore
-   a regular executable helper without following symlinks, and be idempotent. Detection and reporting SHALL
-   NOT rewrite active context, restart a session, or mutate a live fleet.
-9. `FCOM-REQ-09`: The shared resolver SHALL preserve and strictly validate every schema-supported v1
-   connector kind (`tmux`, `discord`, and `matrix`) from YAML and JSON. Every accepted snake/camel alias
-   pair SHALL reject differing dual declarations and accept identical declarations. JSON roster fallback
-   SHALL occur only when `roster.yaml` is absent; all other YAML access failures SHALL fail closed.
-10. `FCOM-REQ-10`: The communications generation SHALL cover the complete canonical rendered semantic
-    contract, including identity, role/class, resolved host/socket/helper, peer metadata, and exact commands.
-    Installed helpers SHALL be validated with no-follow filesystem inspection as regular executable files.
-    Keep-mode reseed and relaunch discovery SHALL preserve and support both YAML and JSON rosters.
-
-### Acceptance criteria
-
-1. `AC-FCOM-01`: Contract fixtures contain no unresolved operational targeting metavariables; local
-   identity contains exact host/session/socket/helper values.
-2. `AC-FCOM-02`: Same-host, cross-host, named-socket, literal-default-socket, and missing-SSH tests prove
-   exact targeting and fail-closed behavior.
-3. `AC-FCOM-03`: Unknown identities and peers report known exact names plus an exact self-scoped
-   discovery command; no fuzzy session selection is emitted.
-4. `AC-FCOM-04`: Four-harness tests prove byte-equal authoritative communications sections.
-5. `AC-FCOM-05`: Source, fresh-install, preserved-custom-install, stale-installed, composed-generation,
-   helper executable, agent-send socket isolation, and exact-target tests pass.
-6. `AC-FCOM-06`: Documentation defines non-mutating stale-context detection and operator-authorized,
-   exact-agent relaunch; no implementation path performs automatic session mutation.
-7. `AC-FCOM-07`: YAML and JSON fixtures cover every connector kind; all snake/camel aliases cover
-   identical acceptance and conflicting rejection; non-`ENOENT` YAML failures do not fall back.
-8. `AC-FCOM-08`: Missing, directory, symlink, and non-executable installed helpers fail closed. Explicit
-   current-version repair proves partial-deletion recovery, digest-qualified backup collision safety,
-   symlink-target safety, and repeated-run idempotence.
-9. `AC-FCOM-09`: Markerless-equal and wrong-version source/installed contracts are stale, and a rendered
-   role/class change produces a different communications generation.

-## KBN-101 Database Runtime/Migration Role Split (#771)
-
-### Problem and objective
-
-PostgreSQL Gateway/storage currently uses one `DATABASE_URL` for runtime queries and migrations. That makes the deployed application identity an owner and prevents certification that KBN immutable event, artifact, checkpoint, and evidence relations reject runtime `UPDATE`/`DELETE`. KBN-101 freezes a least-privilege runtime/migration split before KBN-100 schema work.
-
-### Normative requirements
-
-1. `K101-REQ-01`: `DATABASE_URL` SHALL be the non-owner PostgreSQL runtime connection and `DATABASE_MIGRATION_URL` SHALL be the migration-only owner/migrator connection. They are required respectively for runtime and the dedicated `mosaic-db-migrator --run|--verify` phase in `standalone`/`federated`; local PGlite is the explicit exception. The published `@mosaicstack/db` bin maps exactly `mosaic-db-migrator` to `./dist/cli.js`, its image entrypoint is exactly `mosaic-db-migrator`, accepts no URL/SQL/schema/role argv, and returns stable sanitized exits. Every current/future PostgreSQL DDL entrypoint SHALL route to that runner or be denied, and SHALL reject `DATABASE_URL`-only execution before connection/DDL. Data migration may connect only after the runner prepares and verifies the PostgreSQL target, through dedicated non-DDL `mosaic_data_importer` and exactly `--target-url-file /run/secrets/mosaic-migrate-target-url`, its fixed paired authenticated provider-version file `/run/secrets/mosaic-migrate-target-version`, plus `--target-attestation-file /run/mosaic-attestations/migrate-target.v1.json`. KBN-101-05 obtains URL key `url` and version only from the same successful Vault KV-v2 response at `secret-{env}/mosaic-stack/database/importer` (`data.metadata.version`), renders them as one immutable generation into separate consumer copies, and never infers a provider version from DSN bytes. The trusted runner verifies TLS/identity/manifest, reads its fixed importer URL/version copies only for binding through safe no-follow fd checks, and signs a credential-free JCS/Ed25519 attestation using its runner-only fixed root-owned private-key file; no signing key reaches importer/runtime. The artifact binds secret version and SHA-256 of exact high-entropy credential-file bytes, canonical TLS host/port/database, CA/SPKI, PostgreSQL system identifier/database OID, importer role, manifest/schema fingerprints, producer invocation/build/image digest, issued/expires/nonce, and correlation. Before target connection the importer validates URL/version/attestation/public-key files, signature/key/expiry/replay/authenticated provider version/digest/generation/bindings and the importer-only CA at exact `DATABASE_TLS_CA_CERT_PATH`; after verified TLS and before DML it validates server/database/role/CA/schema identity, with same-fd/in-memory-byte TOCTOU protection, rotation/revocation, a privileged producer-only-to-importer-only artifact handoff controller that verifies/copies/fsyncs/atomically renames/seals before importer start, consumer isolation/no logging-oracle, and sanitized errors. Raw `--target-url`, `DATABASE_URL` fallback, runtime-owner use, missing/unsafe/substituted files, stale/replayed/tampered/wrong-key attestation, wrong binding, and DDL attempt fail before target connection/DDL; post-connect mismatch closes with zero DML/DDL. A reviewed finite classifier inventories executable current source/scripts/package bins, operator docs, deploy manifests, and exact normative contracts by path; active secure records pin both options/files, producer/key/bindings/tests, while normative contracts cannot mask instructions. Unknown active commands, duplicate-owner, ownerless, missing-path, and historical/status-only masking hits fail. `db:push` is forbidden outside an explicitly disposable local developer database and cannot accept a production-like URL.
-2. `K101-REQ-02`: Gateway runtime/replicas SHALL not execute migrations or DDL. The runner SHALL hold one `max:1` session and fixed two-int advisory namespace `1297044289` (`MOSA`), `1262636593` (`KBN1`) across preflight, reconciliation, migration, verification, and release. It SHALL compare the versioned canonical manifest v1 tuple (journal logical index/tag plus exact SQL-byte SHA-256) to the complete observed ledger mapping; count/set-only, timestamps, and physical insertion order are non-normative and insufficient.
-3. `K101-REQ-03`: PostgreSQL SHALL separate non-login platform database owner, non-login schema owner, dedicated `NOLOGIN SUPERUSER` `mosaic_extension_owner`, login migrator, dedicated login non-DDL data importer, non-login runtime capability, and login runtime roles. For PostgreSQL 17 + pgvector 0.8.2, `vector` is untrusted (`trusted` is absent and `relocatable=true`): only an externally controlled audited platform-bootstrap superuser session may `SET ROLE mosaic_extension_owner` for CREATE/UPDATE/SET SCHEMA, then `RESET ROLE`; the role has `rolcanlogin=false`, `rolsuper=true`, zero members, no runtime credential/Vault secret, and is never provided to app containers. It owns `mosaic_extensions`, fresh `vector`, and owner-bearing extension members, while `mosaic_schema_owner` receives only `USAGE` for type resolution and never ownership/`CREATE`/`ALTER`/`DROP`/member-change/default-privilege authority there. Superuser cannot be constrained by `GRANT`/`REVOKE`; this is identity/non-login/no-membership/external-control/audit isolation, not a false least-privilege claim. Extension operations require control-plane change, independent review, backup/rollback, maintenance window, and audit evidence. Managed targets that cannot establish this exact role are ineligible until an independently approved versioned provider-owned extension-owner profile exists; app/migrator ownership is never silently retained. Existing approved-owner extension relocation validates exact `pg_namespace.nspowner`, `pg_extension.extowner`, member ownership/schema/version, while legacy runtime-owned extension fails closed to a controlled shadow-database migration—never unsupported ownership alteration, catalog mutation, ownership adoption, or `DROP CASCADE`. Runtime, migrator, schema owner, importer, and all service roles must fail `SET ROLE`, catalog/direct `ALTER`/`UPDATE`/`DROP`/membership-change denial, role ownership, superuser/role-creation/schema-creation/TEMPORARY, unsafe membership, untrusted search path, missing grants, unauthenticated TLS, and immutable privilege drift checks. Application schema is fixed `mosaic` with exact `pg_catalog,mosaic` session path; historical public migrations remain byte-immutable legacy bootstrap only, every future Drizzle application declaration targets `mosaic`, and `vector` is explicitly qualified from non-writable `mosaic_extensions`. No config-derived SQL identifier is permitted.
-4. `K101-REQ-04`: `mosaicstack/stack` KBN-101-00 SHALL exclusively own `infra/pg-bootstrap/roles.sql`, `infra/pg-bootstrap/extensions.sql`, `infra/pg-bootstrap/README.md`, and bootstrap tests; KBN-101-05 SHALL exclusively own `tools/db/render-postgres-secrets.ts`, its tests, and current Compose/Portainer/two-gateway deployment declarations, consuming the versioned bootstrap interface without overlap. Environment IaC/Vault is named input and Mosaic deployment control plane/Jason is activation authority. Distinct runtime/migrator/importer URL, importer authenticated provider-version, DB-client CA, Gateway leaf, and PostgreSQL server key/certificate materials are provisioned before a production-like database starts. Importer and migrator have separate immutable URL/version copies at fixed `10002:10002`/`10003:10003` identities; runtime/unrelated containers receive neither importer material, attestation private key, or importer artifact. Runtime, migrator, and importer require their mounted CA plus `sslmode=verify-full`. Exact UID/GID/mode/rendering, service-DNS SANs, Vault/compose/Swarm consumer isolation, two-gateway pair ordering, server activation, pre-enforcement legacy-client drain and `hostssl` zero-plaintext-session proof, fresh/existing transition, CA-overlap rotation, TLS-only rollback, and standalone/federated/Swarm/two-gateway positive/negative TLS evidence are required. No application-generated production certificate or plaintext bootstrap exception is permitted.
-5. `K101-REQ-05`: KBN immutable relations SHALL permit the real runtime role INSERT/SELECT only and deny UPDATE/DELETE; parent retention remains RESTRICT/no-cascade. Role/password/Vault creation is external platform control, never application migration/source.
-6. `K101-REQ-06`: N-1 single-URL compatibility, rollout/rollback, Vault ownership/rotation/redaction, CI, installer, compose/Portainer, observability, and deployment handoffs SHALL be separately bounded one-card/one-PR work. Prepared slices remain inactive while current owner-runtime deployments stay N-1; Mosaic control plane/Jason alone authorizes one final atomic activation or rollback, with no force-on-red/bypass. KBN-101 planning itself SHALL not mutate production.
-7. `K101-REQ-07`: KBN-100 SHALL begin only after the KBN-101 foundation role/schema-boundary certificate; it SHALL rebase on that main head, restore generated Drizzle declaration/snapshot/journal consistency, and bound procedural immutable-table grant/trigger/backfill additions to its schema slice. KBN-101 real deployed-role immutable-operation certification SHALL complete after KBN-100 creates those relations and before KBN-105.

-### Acceptance criteria
-
-1. `AC-K101-01`: DTO/command-matrix tests prove required modes, PGlite exception, `mosaic-db-migrator --help|--run|--verify`/stable exits/argv refusal, public-import negative, every finite classified DDL/static-bypass inventory path and both harness pairs reject `DATABASE_URL`-only before connection/DDL, no migration-to-runtime fallback, and `db:push` refusal outside an allowlisted disposable DB. Before inventory, ownership, or status masking, the semantic fixture fails README's exact former commented code-fence generic-wrapper form and the user guide's exact former executable generic-wrapper form; source-consistency proves current `packages/storage/src/cli.ts` directly `execSync`s `pnpm --filter @mosaicstack/db db:migrate` and no `mosaic-db-migrator` bin exists, so runner-delegation documentation fails. The active `docs/guides/migrate-tier.md` route is inventoried to KBN-101-07 and proves runner-produced `--target-url-file /run/secrets/mosaic-migrate-target-url`, fixed paired provider-version file, and `--target-attestation-file /run/mosaic-attestations/migrate-target.v1.json`; runner-only signing/private-key isolation; Vault KV-v2 same-response version provenance, separate immutable generation mounts, importer CA, JCS/Ed25519 signature/key rotation/revocation, atomic artifact, expiry/replay, safe-fd secret-version/digest, canonical TLS/CA/server/database/role/manifest/schema bindings, dedicated non-DDL importer, consumer isolation/no log-oracle, and exact no-connection versus zero-DML rejection for missing/wrong/stale/replayed/tampered/wrong-key/substituted/generation-mismatched inputs. The full current non-normative docs inventory—including user guide, federation historical task/MILESTONES status, and non-operative SETUP—has an exact safe disposition. Scanner semantic checks reject automatic first-boot/startup extension/schema/migration wording, Compose-up-before-runner, init-script authority, production `.env`/monorepo auto-load/`EnvironmentFile=`/credential-export-or-argv/restart-as-secret-activation routes, and every unqualified operator-document `mosaic-db-migrator --run|--verify` hit regardless of named/normative/status classification. The exact former README/dev/deployment Compose-first sequences, former SETUP wording, exact former MILESTONES wording `pgvector extension installed + verified on startup`, former architecture-plan/PERFORMANCE/backlog runner routes, and any unqualified runner fixture fail before inventory masking. Only one `Held future procedure` Markdown section—bounded through the next equal-or-higher heading—may contain the explicit non-operative/no-current-command-authority form that names KBN-101-00/-03/-05 and preserves external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `mosaic-db-migrator --verify` → Gateway/Compose readiness; every runner hit outside that section fails. The README assertion for the checked-in direct CI `pnpm --filter @mosaicstack/db run db:migrate` with `DATABASE_URL` passes only as active legacy N-1, uncertified, non-authorizing-as-an-operator-route status against an isolated disposable CI database pending KBN-101-06 removal—not as an ordinary operator or approved DDL-authority route. Only local PGlite data-layer work or non-PostgreSQL Compose is current (Gateway/Web local startup is held pending daemon/inherited/project-DSN rejection).
-2. `AC-K101-02`: Fixed namespace lock contention/crash/readiness/non-interference and exact manifest-v1 reconciliation tests prove no replica race/runtime auto-migration and fail closed on every missing/unknown/duplicate/ambiguous/corrupt/stale ledger state.
-3. `AC-K101-03`: Actual PostgreSQL 17 + pgvector 0.8.2 control-file, catalog, Drizzle-generation, vector-query/operator, fresh/approved-owner/legacy-shadow/partial/resume/rollback/N-1, and real deployed-role tests prove `trusted` absent/untrusted plus relocatability, external-superuser `SET ROLE` create/update/`RESET ROLE` audit, exact `rolcanlogin=false`/`rolsuper=true`/zero-membership/no-runtime-secret state, platform/schema/extension-owner/migrator/importer/runtime separation, `pg_extension.extowner` plus owner-bearing extension-member/schema/version assertions, and runtime/migrator/schema-owner/importer/all-service-role `SET ROLE`/ALTER/DROP/member-update denial. They also prove `pg_catalog,mosaic` per-session pool safety, `mosaic_extensions` qualification, identifier injection denial, ownership/membership/ledger-read/TEMP/default grants, and unsafe privilege denial.

-5. `AC-K101-05`: Real runtime-role evidence proves INSERT/SELECT succeeds and UPDATE/DELETE fails for every frozen immutable KBN relation.
-6. `AC-K101-06`: N-1/atomic activation/rollback, Vault/CA-overlap rotation/redaction, health/operator behavior, CI/deployment handoff, independent exact-head security review, and terminal-green CI evidence the foundation before KBN-100; after KBN-100, the real deployed-role immutable-operation certificate and Ultron approval release KBN-105.

 ### AC-10: Deployment
 
-- [ ] PGlite data-layer work uses no PostgreSQL; optional Compose services are selected individually and do not start PostgreSQL; Gateway/Web local start remains held until KBN-101-02 rejects daemon/inherited/project DSNs before connection or DDL
-- [ ] PostgreSQL/federated activation is unavailable until KBN-101-00/-03/-05 deliver external bootstrap, TLS/roles, runner `--run`, runner `--verify`, and Gateway/Compose readiness in that order
-- [ ] `mosaic` CLI installable and functional on bare metal after the reviewed KBN-101-05 secret-renderer/process-exec or `LoadCredential` interface exists
-- [ ] Local-only configuration documentation is distinct from production generation-pinned Vault-rendered consumer material
+- [ ] `docker compose up` starts full stack from clean state
+- [ ] `mosaic` CLI installable and functional on bare metal
+- [ ] Database migrations run automatically on first start
+- [ ] `.env.example` documents all required configuration

-## Verdict — 5/6 PASS; BUILD ADMISSION: **NO**
-
-| Probe | Verdict | Short result |
-| --- | --- | --- |
-| P1 launcher topology + ancestry | **PASS** | Real Mosaic→Pi and Mosaic→Claude chains reached the registered anchor; real Claude `SessionStart` hook ancestry accepted; same-UID sibling with the minted victim ID rejected. |
-| P2 Pi last-position + nonce map | **PASS** | Real Pi proved last-or-closed; `message_end` mapped exact `toolCallId → requestNonce` before `tool_call`; provider-response hook occurred before stream consumption/content completion. |
-| P3 same-PID generation revocation | **PASS** | Same Pi PID/starttime persisted through reload/fork/new/resume while broker generations increased; reload revoked a prior `VERIFIED` generation. |
-| P4 `SO_PEERCRED` + socket posture | **PASS** | Real Unix socket peer PID/UID/starttime matched `/proc`; 0700 directory + 0600 socket demonstrated. Same-UID counterfeit replacement remains explicitly T-C without a distinct principal/authenticated response. |
-| P5 source invalidation | **PASS** | Missing, oversize, and hash-mismatched fragments each refused injection/promotion, revoked broker state, and blocked the exact emitted tool call. |
-| P6 atomic injection | **T-C GAP** | Both runtimes empirically delivered a complete single block/message, but neither installed runtime contract states an **atomic/prefix-preserving** transport guarantee. Observation is not a guarantee; A-v5-1/T27 cannot be admitted. |
-
-**Planner return item:** P6. The evidence establishes successful complete delivery in these runs, not the required invariant that the harness cannot middle-drop/replace bytes while preserving the terminal token. Per R1, such a middle-drop is not receipt-detectable. It is therefore classed **T-C**, not assumed away.

-All three **MATCH**. They were read in full before probe construction. Raw artifact: [`evidence/raw/STEP0-authority-hashes.txt`](./evidence/raw/STEP0-authority-hashes.txt).
-
-## Evidence method
-
-The scripts under [`probes/`](./probes/) are isolated Gate0 instrumentation, not product implementation. They run the installed `mosaic yolo` launcher and real installed runtime binaries. Broker prototypes use Linux `SO_PEERCRED` and `/proc`; runtime adapters are temporary Claude hooks/Pi extensions. No product source under `packages/mosaic` was changed.
-
-Raw-output artifact integrity is indexed at [`evidence/RAW-SHA256SUMS.txt`](./evidence/RAW-SHA256SUMS.txt).

-## P1 — Launcher exec/parent topology + supported-hook ancestry (D1)

-**Verdict: PASS**

-- [`evidence/raw/P1-claude-hook-events.txt`](./evidence/raw/P1-claude-hook-events.txt)
-
-### Real topology observed
-
-The installed Mosaic launcher does **not** replace itself with the runtime despite its `execRuntime` name; installed `launch.js:668` uses `spawnSync`. The Gate0 anchor first registered, then `execvpe` replaced the anchor with the real `mosaic yolo` process (PID/starttime retained). Mosaic remained the stable parent while it spawned the runtime.
-
-Pi run:
-
-```text
-anchor before exec: pid=4010843 starttime=365919858 exe=/usr/bin/python3.11
-anchor after exec:  pid=4010843 starttime=365919858 exe=/usr/bin/node
-Pi runtime:         pid=4011046 ppid=4010843 starttime=365920219 exe=/usr/bin/node

-
-Claude supported-hook run (latest capture):
-
-```text
-hook python  pid=4011380 starttime=365920845
-  -> /bin/sh pid=4011379 starttime=365920845
-  -> claude  pid=4011285 starttime=365920748
-  -> node/mosaic anchor pid=4011129 starttime=365920380
-```
-
-The stream independently recorded the real hook firing:
-
-```json
-{"type":"system","subtype":"hook_started","hook_name":"SessionStart:startup","hook_event":"SessionStart"}
-{"type":"system","subtype":"hook_response","hook_name":"SessionStart:startup","exit_code":0,"outcome":"success","stdout":"...GATE0_P1_SUPPORTED_HOOK_ANCESTRY_ACCEPTED..."}
-```
-
-### Authentication and sibling substitution
-
-The broker minted the logical ID on first peercred contact and keyed the anchor by `(pid,starttime)`. It took the hook/extension PID from `SO_PEERCRED`, walked `/proc/<pid>/stat`, and re-read every starttime before accepting.
-
-Real Pi acceptance excerpt:
-
-```json
-{"peercred":{"pid":4011046,"uid":1001,"gid":1001},"decision":"ACCEPT","reason":"ancestry-reaches-registered-anchor","starttimes_rechecked":true}
-```
-
-A separately spawned same-UID sibling was given the real minted victim ID. Its ancestry did not reach the anchor:
-
-```json
-{"attacker_uid":1001,"victim_session_id_known":true,"broker_decision":"REJECT","broker_reason":"victim-id-known-but-ancestry-mismatch"}
-```
-
-The same rejection occurred in both Pi and Claude runs. This is positive runtime evidence for D1/T15a under the supported non-daemonizing topology.

-## P2 — Pi last-position invariant + nonce map (D5)
-
-**Verdict: PASS**
-
-### Commands
-
-```bash
-python3 docs/compaction-refresh/probes/pi_gate0_run.py
-python3 docs/compaction-refresh/probes/p2_provider_timing_run.py
-```
-
-Full outputs:
-

-- [`evidence/raw/P2-provider-timing.txt`](./evidence/raw/P2-provider-timing.txt)
-
-### Last-or-closed evidence
-
-Real Pi argv/load order with the probe last:
-
-```json
-{"extensions":[".../mosaic-extension.ts",".../pi_gate0_extension.ts"],"lastPosition":true,"gateState":"UNVERIFIED_READY","pid":4004545}
-```
-
-A second real Pi launch deliberately appended a later handler:
-
-```json
-{"extensions":[".../mosaic-extension.ts",".../pi_gate0_extension.ts",".../pi_later_extension.ts"],"lastPosition":false,"gateState":"CLOSED_NOT_LAST","pid":4005692}
-```
-
-Thus the invariant observed is exactly **last or closed**, not an asserted registration order.
-
-### Exact nonce → tool-call-ID map
-
-In one real GPT-5.6 Sol Pi response, sequence 5 completed the assistant tool-call message and bound its exact ID:
-
-```json
-{"seq":5,"event":"message_end","requestNonce":"e5a82358-a6c9-490b-a0de-2e1f1d9b8d79","toolCallIds":["call_bgGE...57c"],"nonceMappings":[{"toolCallId":"call_bgGE...57c","requestNonce":"e5a82358-a6c9-490b-a0de-2e1f1d9b8d79"}]}
-```
-
-The following `tool_call` was sequence 6 and carried the same ID/nonce:
-
-```json
-{"seq":6,"event":"tool_call","toolCallId":"call_bgGE...57c","mapping":{"nonce":"e5a82358-a6c9-490b-a0de-2e1f1d9b8d79","verified":true},"allowed":true}
-```
-
-The harmless tool executed at sequence 7 with that same tool-call ID. No session-global “current epoch” was borrowed.
-
-### `after_provider_response` is not assistant-content observation
-
-A deterministic localhost HTTP provider was used only to force headers/status exposure through the real Pi transport. Actual order:
-
-```json
-{"seq":4,"event":"before_provider_request"}
-{"seq":5,"event":"after_provider_response","status":200,"assistantContentAvailableAtThisHook":false,"timing":"headers/status before stream consumption"}
-{"seq":6,"event":"message_end","role":"assistant","assistantContentObserved":true}
-```
-
-```text
-headers_hook_precedes_completed_message=True
-```
-
-This positively confirms SPEC-v5’s precision correction: receipt content is observed at `message_end`; `after_provider_response` is status/headers before stream consumption.

-## P3 — Same-PID `runtime_generation` bump revokes prior lease (D4)
-
-**Verdict: PASS**
-
-### Command
-
-```bash
-python3 docs/compaction-refresh/probes/pi_gate0_run.py
-```
-
-Full output: [`evidence/raw/P2-P3-P5-P6-pi.txt`](./evidence/raw/P2-P3-P5-P6-pi.txt).
-
-The real Pi process identity remained:
-
-```text
-pid=4004545 starttime_ticks=365907677 uid=1001
-```
-
-Broker state around reload:
-
-```json
-{"event":"runtime_generation_bump","reason":"startup","old_generation":0,"new_generation":1,"new_lease_state":"UNVERIFIED"}
-{"event":"probe_lease_promoted","generation":1,"new_lease_state":"VERIFIED"}
-{"event":"runtime_generation_bump","phase":"shutdown","reason":"reload","old_generation":1,"new_generation":2,"prior_lease":"VERIFIED","prior_lease_revoked":true,"new_lease_state":"REVOKED"}
-{"event":"runtime_generation_bump","phase":"start","reason":"reload","old_generation":2,"new_generation":3,"new_lease_state":"UNVERIFIED"}
-```
-
-The same `(pid,starttime)` then emitted monotonic bumps for real `fork`, `new`, and `resume` replacement flows, reaching generation 12. Pi 0.80.7 emitted an additional conservative `session_start` callback in each of those replacement flows; the broker bumped again rather than reusing authority. This is an availability/idempotence consideration for implementation, not a fail-open result.

-## P4 — `SO_PEERCRED` + socket authenticity posture
-
-**Verdict: PASS, with the spec’s named same-UID T-C residual**
-
-### Command
-
-```bash
-python3 docs/compaction-refresh/probes/p4_peercred_probe.py
-```
-
-Full output: [`evidence/raw/P4-so-peercred.txt`](./evidence/raw/P4-so-peercred.txt).
-
-Captured real socket result:
-
-```text
-server_pid=4013762 server_uid=1001 server_gid=1001
-directory_mode=0700 socket_mode=0600
-SO_PEERCRED pid=4013768 uid=1001 gid=1001
-client_claim={"pid":4013768,"starttime_ticks":365927069,"uid":1001,...}
-proc_observed={"pid":4013768,"starttime_ticks":365927069,"uid":1001,...}
-pid_match=True
-uid_match=True
-starttime_match=True
-client_exit_status=0
-```
-
-Achievable unprivileged posture on this host is a user-owned 0700 parent plus 0600 socket. That excludes other UIDs and positively authenticates the connecting kernel PID/UID/GID. It does **not** stop another process running as `hermes` from unlinking/rebinding the socket. A claim stronger than T-C against counterfeit replacement therefore requires the ratified distinct-principal system service or authenticated broker responses. No stronger claim is made.

-## P5 — Source invalidation fail-closed

-**Verdict: PASS**

-
-Full output: [`evidence/raw/P2-P3-P5-P6-pi.txt`](./evidence/raw/P2-P3-P5-P6-pi.txt).
-
-Each fault was injected into the manifest/source read by the real Pi `context` hook. Each run reached an actual model-produced `toolCallId`, then the runtime gate refused it:
-
-| Fault | Runtime validation | Injection/promotion | Broker | Tool result |
-| --- | --- | --- | --- | --- |
-| Missing path | `reason=missing` | `injectionDecision=REFUSED`, `promotion=false` | `source_invalidation_revoke` | `allowed=false`, `unverified-source:missing` |
-| 65 bytes with 64-byte max | `reason=oversize` | `REFUSED`, `promotion=false` | revoked | `allowed=false`, `unverified-source:oversize` |
-| Bytes differ from pinned SHA-256 | `reason=hash-mismatch` | `REFUSED`, `promotion=false` | revoked | `allowed=false`, `unverified-source:hash-mismatch` |
-
-Missing example:
-
-```json
-{"event":"context_return","sourceValidation":{"ok":false,"reason":"missing"},"injectionDecision":"REFUSED","promotion":false,"sourceBroker":{"event":"source_invalidation_revoke","new_lease_state":"REVOKED"}}
-{"event":"tool_call","mapping":{"verified":false,"sourceReason":"missing"},"allowed":false,"reason":"unverified-source:missing"}
-```
-
-No fault case reached tool execution or promotion.

-## P6 — Atomic Claude `additionalContext` + Pi `context` injection (A-v5-1 / T27)

-python3 docs/compaction-refresh/probes/p6_claude_run.py
-rg -n -i "atomic|prefix-preserv" <installed Pi and Claude hook docs>

-- [`evidence/raw/P6-contract-gap.txt`](./evidence/raw/P6-contract-gap.txt)
-
-### Positive empirical observations
-
-**Pi:** The real `context` hook returned exactly one additional `AgentMessage`; the prior message prefix hash was unchanged. The real final provider payload contained exactly one occurrence in one content item, and the real model copied all bytes exactly:
-
-```json
-{"event":"context_return","inputCount":1,"outputCount":2,"injectionDecision":"ONE_ATOMIC_AGENT_MESSAGE","prefixPreservedByReturn":true,"blockLength":108,"blockSha256":"99c3...a0dd"}
-{"event":"before_provider_request","markerOccurrences":1,"markerPaths":["$.input[1].content[0].text"],"finalPayloadValid":true}
-{"event":"message_end","exactContextBlockCopied":true,"assistantTextSha256":"99c3...a0dd"}
-```
-
-**Claude:** The real `SessionStart` hook emitted one `hookSpecificOutput.additionalContext` string. Claude’s stream recorded successful hook execution, and the real model’s exact copied block matched byte length and SHA-256:
-
-```text
-block_length=116
-block_sha256=ef6377d63552af075f4f4adec00165988418c5f46a992f4dce8e678b56fd34ac
-assistant_copy_length=116
-assistant_copy_sha256=ef6377d63552af075f4f4adec00165988418c5f46a992f4dce8e678b56fd34ac
-assistant_copy_exact=True
-```
-
-### Why this is not a PASS
-
-The installed Pi documentation says only that `context` receives a deep copy and may return `{ messages }`. The installed Claude documentation says only that `additionalContext` enters/adds to context/system prompt. The exact search result was:
-
-```text
-NO MATCH: neither installed runtime document states an atomic/prefix-preserving transport guarantee.
-```
-
-One or several successful complete deliveries cannot prove the transport invariant needed by A-v5-1. In particular, a harness-side middle deletion/replacement that preserves the terminal receipt is not detectable by the receipt. That is precisely R1’s assurance boundary. Therefore:
-
-- absent or prefix-truncated terminal token: receipt-detectable;
-- middle-drop preserving the tail token: **not receipt-detectable**;
-- no documented runtime contract excludes that transform;
-- classification: **T-C contract gap**.
-
-No atomicity claim is inferred from empirical success.
-
----
-
-## Independent probe review
-
-After an initial review identified a session-global P2 correlation flaw, the probe was changed to queue request-scoped cycles from `before_provider_request` through assistant `message_end`; all runtime probes were re-run and raw checksums regenerated. The final independent review command was:
-
-```bash
-~/.config/mosaic/tools/codex/codex-code-review.sh \
-  -b d801d6c4c8a984d6a95033c49714210018d3d9a8 \
-  -o /tmp/827-gate0-rereview.json
-```
-
-Final review: **APPROVE**, confidence 0.91, 18 files reviewed, 0 blockers, 0 should-fix findings, 0 suggestions.
-
-## Final admission decision
-
-Gate0 requires every item to produce positive runtime evidence. P6 does not. **Do not admit WI-1..WI-7. Return A-v5-1/T27 to planner review.**
-
-No feature work, push, PR, merge, or issue closure was performed.

-# Gate0 Probe-3 (D4) Class-B — §3-Conformance Review v3
-
-**Verdict: ✅ PASS**
-
-## Pin (G1 — reviewed object, mandatory)
-
-- **Reviewed object = `ace6066762c088f4b9729860da71b4c84451a7c3`** (harness commit, branch `feat/827-gate0-probe`, `mosaicstack/stack` @ git.mosaicstack.dev).
-- **Reviewed file:** `docs/compaction-refresh/probes/p3_d4_focused_run.py`
-- **Harness sha256 (pushed provider bytes, fetched `-o FILE`, FULL-40 ref, verified before trust):**
-  `2f11c9391c0eef203f26b1206bee8bc4cd106e8c1192399c5e7b71f41a3f6b75` (17162 bytes; no not-found sentinel).
-- **§3 amendment authority read at pin:** `GATE0-PROBE3-EXEC-AMENDMENT.md` @ ref `571f239154c6793fb1a5eac0d1cd4182f286a3ac`,
-  sha256 `9ac9ff873fad41a6e15763cc89cb94d0bc4a6b0cf9b6770561d1781b03f63276` (7699 bytes). MUST-HAVE/MUST-BE-ABSENT
-  confirmed against the actual fetched §3 text, not a paraphrase.
-
-## Independence (G2)
-
-Distinct Opus §3-conformance reviewer (Gate-16 author≠reviewer). I did **not** build this harness (author =
-ms-rev-826); I am not Mos. This verdict is my own; the author did not author or edit it. Byte review only — **ran
-nothing** (no harness, no broker, no sockets/state). Reviewed across v1 (FAIL, live-broker launch path) → v2 (PASS,
-later found runtime-dead producer) → this v3 (closes the live-path review-gap).
-
-## Why v3 (the review-gap closed)
-
-v2 PASS @`839d156f` credited the static presence of `lease_anchor_registered` as isolation proof. At FIRE the
-producing path was **dead**: the harness drove the *released* `mosaic` binary, which launched Pi **ungated**, so
-`register_anchor` never ran. Static presence of an assertion ≠ its producing path executing. v3 requires the
-producing path to be **live at runtime**.

-## Verdict
-
-**PASS @ `ace60667`** — (a) LIVE-PATH, (b) fail-closed precondition, (c) fixture-socket isolation, and
-(d) intact assertion all hold, with zero out-of-scope surface. The v2 review-gap (runtime-dead producer via the
-released ungated `mosaic`) is structurally closed: the harness no longer invokes `mosaic` at all — it invokes the
-pinned `abd2791f` `launch-runtime.py` directly (register-before-exec), and refuses to launch unless the launcher is
-that pinned gated register-before-exec binary bound to this run's fixture socket.
-
-**Findings: none.**
-
-## Scope reminder (not a finding)
-
-Per §3/§5 of the amendment, producing this evidence **executes** the Gate0 mechanism (launches processes, creates
-socket/state artifacts, exercises revocation). This review clears the **bytes**; **FIRE remains separately gated on
-Mos's explicit post-clear GO** and is not authorized by this review.

-Distinct Opus §3-conformance reviewer (Gate-16 author≠reviewer). I did not build this harness (author = ms-rev-826);
-I am not Mos. This verdict is my own; the author did not author or edit it. Byte review only — **ran nothing** (no
-harness, no broker, no sockets/state). Prior v3 PASS (`ace60667`, pinned `abd2791f`) is correctly **superseded**:
-pinning a pre-`66b1e0a0` ancestor made D4 an in-memory socket simulation (hollow gate). v4 requires
-mechanism-fidelity within isolation (Jason R1).

-|---|---|---|---|
-| i | Extension bumps `generation-{sid}.state` via the real helper, not in-mem | ✅ | ext `lifecycle()` calls `broker({action:'bump-generation'})` at every post-start boundary (harness :200-205); broker `bump-generation` → `bump_runtime_generation(generation_environment(identity))` (broker :119-120) |
-| ii | Broker reads generation via `read_runtime_generation`, not an in-mem counter | ✅ | broker loads the pinned module (`--generation-module`, :52-54); `file_generation()` = `read_runtime_generation(...)` (:77-78); authorize-probe reads `current_generation = file_generation(identity)` (:154); lifecycle `new_generation = file_generation(identity)` (:201). The in-mem `generations` dict is only an old-value cache for the monotonic guard (:199-204), never the authorization authority |
-| iii | `assert_d4` observes the FILE-BACKED transition | ✅ | `state_file_source` = all records `generation_source=="state-file"` (harness :370-372); `state_file_drives_lifecycle` = state-bumps == lifecycle generations[1:] (:368-369); `new_generation_unverified→MUTATOR_UNVERIFIED` :382; `prior_generation_stale→STALE_GENERATION` :383; `verified_revoked_on_reload` :380-381 — not a socket-only bump |

-## MUST-BE-ABSENT sweep
-
-`P5` / `P6` / `P2-bank` / `retry-launder` / `mosaic yolo` / `execRuntime` / `run_open` / `atomic-observation` /
-`pi_gate0_run` = **0 hits** (both files). Extension invokes only `bump-generation` / `lifecycle` /
-`authorize-probe` / `promote-probe`. No live/prod/real-broker path (single fixture broker; allow-list env; launcher
-pinned to fixture socket). No `.state`/gen-file path outside the fixture temp root (broker `generation_environment`
-raises otherwise). §4 live effect: none. No extra broker/socket beyond the single p3. No exec-at-import (both files
-`__main__`-guarded). Mechanism change is confined to the mandated R1 observation-fidelity deepening + BAR4 hardening;
-no scope-widen of what the probe touches.
-
-## Observations (transparency — not findings)
-
-1. The fixture broker retains a **dormant `source-invalid` action** (:179-194, P5-adjacent, in-mem). It is
-   **never invoked** by the harness or its embedded extension (verified: extension actions are only
-   bump/lifecycle/authorize/promote), and `assert_d4` never observes it — so the probe does **not** exercise or bank
-   P5. Pre-existing shared-fixture code, unchanged. Surfaced so Mos may, if desired, apply a stricter
-   purge-dormant-P5-from-the-fixture standard; under the "what the probe TOUCHES/does" framing it is not a violation.
-2. Fixture `HOME` receives a **read-only copy** of the operator's `~/.pi/agent` `settings.json`/`auth.json`/`bin/fd`
-   (:430-440, `shutil.copy2` into the fixture) so real Pi can authenticate to the model provider. It reads operator
-   state; it does not write/mutate operator HOME and does not emit/log credential material. Confined to the fixture.
-
-## Verdict
-
-**PASS @ `48484938`** — BAR1 (traceability to shipped f4008307 mechanism) + BAR2 (genuine file-backed generation,
-i–iv) + BAR3 (live-path / fail-closed precondition / isolation / intact assertion) + BAR4 (b4-1..b4-5) all hold,
-with zero out-of-scope surface exercised. The v3 hollow-gate (ancestor pin, in-mem simulation) is structurally
-closed: evidence now attests the shipped WI-3 D4 file-backed generation mechanism, launcher pinned by head+sha256,
-child env write-confined by allow-list, integrity `-O`-safe with a derived PASS.
-
-**Findings: none.**
-
-## Scope reminder (not a finding)
-
-Per §3/§5 of the amendment, producing this evidence **executes** the Gate0 mechanism. This review clears the
-**bytes**; **FIRE remains separately gated on Mos's explicit post-clear GO** and is not authorized by this review.

-This review is produced by a **distinct independent Opus §3-conformance / SECREV session** (Gate-16 author≠reviewer),
-**byte review only, ran nothing**, that **did not build** this harness (author = ms-rev-826) and **is not Mos**. The

-
-## Hygiene delta (v4 `48484938` → v5 `7f975b95`) — items (a)+(b): CLOSED
-
-Full `diff` of both files shows the delta touches **only** these:
-
-- **(a) Creds scrubbed — CLOSED.** New `scrub_fixture_credentials(root)` (:467-475): `shutil.rmtree(root/"home"/".pi"/"agent")` then a fail-closed re-check `if copied_agent.exists(): raise` (:473-474). Invoked in the **outermost `finally`** (:598), **after** pi/broker cleanup and **before** `return root` (:600) — so it runs on the **success path too**. The scrub target exactly matches the only copy site (`target_agent = fixture_home/".pi"/"agent"`, :433). `isolated_environment` was moved inside the `try` (:485) so the scrub finally also covers a partial env-setup failure. No copied agent credential/config subtree (incl. `auth.json`) survives in any retained root. ✅
-- **(b) `source-invalid` handler REMOVED — CLOSED.** `grep source-invalid / source_invalidation_revoke == 0` across **both** files. Broker delta is solely the deletion of the old `:179-194` block. ✅
-
-## (c) Everything-else byte-stable vs `48484938` — HOLDS
-
-Diff confirms **no other hunks**. Re-swept intact: traceability `GATED_WI_HEAD=f4008307` (:33) + `GATED_LAUNCHER_SHA256=e950e4224e…` (:35); fidelity `read_runtime_generation`/`bump_runtime_generation` + `generation_source=="state-file"` + `new→MUTATOR_UNVERIFIED`/`prior→STALE_GENERATION`; `lease_anchor_registered` + `hex-256`; `-O`-safe (0 bare `assert`, PASS derived `all(checks.values())`); allow-list literal env (0 `os.environ.copy`); `--runs choices=(3,)`; fail-closed precondition; single p3 broker. Blockers 1-4 (inherited env / `--runs`≠3 / cleanup-misses-setup-failure / `-O`-strips-checks) remain closed.
-
-## (d) ABSENT sweep — 0
-
-`P5`/`P6`/`P2-bank`/`retry-launder`/`mosaic yolo`/`execRuntime`/`run_open`/`atomic`/`pi_gate0` = 0 (both files);
-extension invokes only `bump-generation`/`lifecycle`/`authorize-probe`/`promote-probe`; no exec-at-import.
-
-## Homelab carry-forward — NEW-5 / NEW-6: **PRESENT → FAIL**
-
-### 🔴 NEW-6 — GATED_WI_ROOT resolves wrong / non-portably (CONFIRMED)
-`GATED_WI_ROOT = HERE.parents[3].parent / "stack-cr-wi3-revoke"` (:32). For the harness at
-`…/agent-work/stack-cr-wi0-gate0/docs/compaction-refresh/probes/`, this computes
-**`/home/hermes/stack-cr-wi3-revoke` — which does not exist**. The actual f4008307 worktree is
-`/home/hermes/agent-work/stack-cr-wi3-revoke` = `HERE.parents[3] / "stack-cr-wi3-revoke"`. The traversal is
-**off-by-one** (`.parents[3].parent` should be `.parents[3]`), and it additionally hardcodes the worktree name — a
-non-portable relative assumption. On this host the precondition therefore fail-closes ("gated WI launcher is
-unavailable") and the probe cannot locate/execute the pinned launcher at all. **Real resolution defect** (independently
-computed by path arithmetic; harness not run). **file:line — :32.**
-*Fix:* derive `GATED_WI_ROOT` from a portable, explicit anchor (e.g. an env-provided path validated to be the
-f4008307 worktree, or `HERE.parents[3] / "stack-cr-wi3-revoke"` with existence+HEAD assertion), not `.parents[3].parent`.
-
-### 🔴 NEW-5 — launcher precondition is check-then-exec, not pinned-executed-bytes (CONFIRMED)
-The precondition hashes `launcher_bytes = GATED_LAUNCHER.read_bytes()` (:280) against `GATED_LAUNCHER_SHA256` (:287),
-but the launcher is **executed separately** via `PiRpc([sys.executable, str(GATED_LAUNCHER), …])` (:514-515), which
-opens and **re-reads the file at exec time**. There is **no fd-handoff and no exec-from-verified-copy**, so the
-verified snapshot does **not** bind the executed bytes. The window between check (:287) and exec (:514-515) spans the
-broker `Popen` + `wait_path` (≤20 s) — a genuine **check-then-exec TOCTOU / mutable-path trust**; the `git rev-parse
-HEAD` check (:285-286) is likewise on a mutable HEAD, not the executed bytes. Per the bar this is a real gap.
-**file:line — hash :280/:287 vs exec :514-515.**
-*Fix:* execute the exact verified bytes with no window — e.g. read once, verify, and exec from a fixture-private
-copy of the verified bytes (or `python3 /proc/self/fd/<verified-fd>`), so the hashed bytes == executed bytes.
-
-## Verdict
-
-**FAIL @ `7f975b95`.** The hygiene delta itself is correct — (a) creds scrub (fail-closed finally, success path,
-every retained root) and (b) `source-invalid` removal both landed cleanly, (c) everything else is byte-stable vs
-`48484938`, and (d) the absent sweep is 0. **However**, homelab's NEW-5 (check-then-exec launcher TOCTOU / not
-pinned-executed-bytes) and NEW-6 (GATED_WI_ROOT off-by-one/non-portable resolution) are **present in these bytes**;
-the addendum requires both **closed** for PASS. Not softened. Returns to author (ms-rev-826) — not to a builder
-re-review, no PASS-launder.
-
-**Findings:** NEW-6 (`p3_d4_focused_run.py:32`); NEW-5 (`p3_d4_focused_run.py:280/:287` vs `:514-515`).
-
-## Scope reminder (not a finding)
-
-Producing this evidence **executes** the Gate0 mechanism (§3/§5). This review clears **bytes** only; FIRE remains
-separately gated on Mos's explicit post-clear GO — and is moot until this FAIL is remediated.

-**Anchors.** Harness sha256 matches (27366 B). review-v6 (`23c0caca`) parent == harness commit
-`2d54a9dd`; review touches only the review `.md` (+82 lines, 1 file). Broker
-(`p3_generation_broker.py`) delta vs `48484938…` = **exactly** the 16-line `action=="source-invalid"`
-handler purge, byte-stable otherwise.
-
-**NEW-6 (GATED_WI_ROOT off-by-one) — CLOSED.** `resolve_gated_wi_root()` selects the worktree by
-`git worktree list --porcelain` enumeration, requires a UNIQUE match on `HEAD==GATED_WI_HEAD`
-(`f400830738998db105107a2a4c69c7f2a2a6fd5d`) AND `branch==refs/heads/feat/830-compaction-revoke`,
-then fail-closed re-validates (`is-inside-work-tree==true`, `rev-parse HEAD==GATED_WI_HEAD`);
-`RuntimeError` on ambiguity/mismatch. The `HERE.parents[3].parent / "stack-cr-wi3-revoke"` off-by-one
-and the hardcoded `/home/hermes/...` literal are **gone** — portable, zero hardcoded path.
-
-**NEW-5 (TOCTOU / pinned-executed-bytes) — CLOSED via approach (i), as mandated.** The `git`-object
-sha256 pin (`GATED_LAUNCHER_SHA256 = e950e422…`) is the trust anchor. Ordering/marker `.find()`
-heuristics are downgraded to explicitly diagnostic-only ("never a substitute for the pin"). In
-`launch_verified_pi()` the executed working-tree file is re-hashed against the pin **in the statement
-immediately before `Popen`** (no interleaved yield/IO), and the launcher is executed **in place at the
-pinned worktree path** — the higher-risk approach (ii) copy-to-fixture (previously at `7ff63cd5` /
-`6164dc07`) is **reverted** (the only remaining `shutil.copy2` is the legitimate credential copy, not a
-launcher copy). Residual sub-statement TOCTOU window on a local file inside a non-adversarial operator
-fixture is within this probe's threat model; the gross precondition→much-later-exec gap homelab flagged
-is closed.
-
-**Hygiene — CLOSED.** `scrub_fixture_credentials(root)` removes the entire `.pi/agent` subtree in a
-`finally` block (nested try/finally, after `pi.close()` + broker shutdown, before `return root`) and
-`RuntimeError`s if the scrub fails — credentials are removed from retained evidence; logs retained.
-
-**Invariants byte-stable (all INTACT):** assertion `lease_anchor_registered`; file-backed fidelity
-checks (`generation_source=="state-file"`, `state_file_in_fixture_root`, `MUTATOR_UNVERIFIED`,
-`STALE_GENERATION`); `-O`-safe (0 bare `assert`); allow-list env (0 `os.environ.copy`); single broker;
-`--runs choices=(3,)`; ABSENT-sweep (`yolo`/`execRuntime`/`p3_bank`/`promote_p2`/`retry`) = 0.
-
-**R1 mechanism-fidelity boundary — HELD.** D4 exercises #830's real file-backed revocation
-(`generation-{sid}.state` / `MOSAIC_LEASE_GENERATION_FILE`, from `66b1e0a0`); `.state` stays inside the
-fixture temp root; fixture-socket / child-write-escape / gettempdir isolation preconditions preserved;
-launcher exec is in place at the pinned worktree (same surface as R1, not a new production/live
-surface). **No path escapes the fixture root.** BEYOND-R1 tripwire NOT tripped.

-## Independence
-
-- **Substantive principal-independence** of review-v6 is satisfied by an orchestrator-dispatched,
-  builder-distinct Opus SECREV (`ms-secrev-828`, byte-only, non-builder) — that IS the substance of
-  Gate-16.
-- The shared `ms-lead-reviewer` git signer on harness+review commits is **evidentiary, not
-  substantive**. It is resolved by (1) this Mos co-attestation committed under a **distinct** identity
-  (`mos-orchestrator`), and (2) a homelab third-principal verify under its own distinct identity —
-  i.e. three distinct-identity principals of record.
-- The shared signer is a tracked **fleet-infra tooling-gap** (durable fix = per-lane distinct signers),
-  **not a blocker**.
-
-## Scope of this record — byte-clear, NOT fire-authorization
-
-Producing probe evidence **executes** the Gate0 mechanism; a byte-clear is not a fire-authorization.
-This co-attestation clears the **bytes/scope/hygiene**. FIRE remains gated on: **homelab
-third-principal verify** + **Mos transparency-to-Jason** (real-Pi consumes operator model creds inside
-the isolated fixture, scrubbed post-run, never emitted) + **Mos explicit FIRE GO**. Until then: nothing
-banked, WI-3 #830 held at `f4008307` (unmoved), C-hatch armed (if 3× isolation still no-fire /
-wrong-value / isolation-FAIL → possible Case-C → STOP + escalate to Jason).
-
-**Mos verdict: byte-scope + mechanism + hygiene PASS. Co-attestation of record — committed.**
-
----
-
-## ⚠️ SUPERSEDED — homelab third-principal FAIL raised a stricter bar (evidence-integrity note)
-
-This co-attestation was **byte-clear on the v6 bar ONLY** and self-limited above to *"byte-clear
-ONLY, NOT fire-authorization; FIRE remains gated on homelab third-principal verify."* Homelab (the
-required third principal) subsequently returned **FAIL @2d54a9dd**, and Mos **UPHELD** it — so the v6
-byte-clear this document records is **SUPERSEDED** and does **NOT** authorize FIRE.
-
-Homelab's substantively-correct deepening (accepted as gate-**strengthening**, not softening):
-1. `launch_verified_pi` hashes the launcher then `Popen`/execve **reopens the path** → statement
-   adjacency shrinks but does not eliminate TOCTOU; hashed-snapshot ≠ executed-bytes.
-2. `lease_generation.py` helper is unpinned, loaded from the mutable worktree → HEAD + launcher-pin
-   do not bind the helper bytes.
-3. `p3_generation_broker.py` executes from the mutable worktree unhashed → reviewed broker bytes need
-   not be the evidence-producing bytes.
-
-For a fail-closed DO-178C evidence gate, **hashed==executed must hold on the FULL executed closure**
-(launcher + helper + broker), which v6 (approach (i) adjacency) does not meet. Mos therefore
-**authorized approach (ii) full-closure materialization** (SHA-pin + materialize the full closure into
-a fixture-private 0700/0600 dir or held verified fds, exec from there, launcher+broker consume the same
-pinned helper; re-hash==f4008307 pins immediately before exec, fail-closed). This rides the existing R1
-authorization + Mos adjudication authority (it deepens isolation of already-authorized touch and stays
-inside the fixture temp root → R1 owner tripwire not tripped; no fresh owner window).
-
-**Live target = v7** (materialized-closure harness, forthcoming). `2d54a9dd` / `23c0caca` / this
-co-attestation (`12914d8`) are **SUPERSEDED**. A fresh Mos co-attestation will be committed on v7
-byte-verify PASS. WI-3 #830 remains HELD at `f4008307`; nothing banked; C-hatch armed.

-
-**B9 — no-site startup closure (homelab 4th-round finding CLOSED).** Both child command lists now
-carry `-S`, which disables the `site` module entirely (no `.pth` executable lines, no
-`sitecustomize`/`usercustomize`) so no unpinned startup code runs before the exact launcher/broker or

-- broker `launch_verified_broker` (`:554`): `-I` + **`-S`** + `-B`.

-Homelab's finding was **independently reproduced by Mos** and the fix **empirically verified** on host

-untouched by `-S` → no B6c regression); `[-I -S -B]`→`no_site=1`. The launcher deliberately omits `-I`
-(B6c: on 3.11+ `-I` implies `-P`, dropping the script dir from `sys.path[0]` → sibling import breaks);

-> Note: `f4008307` (the held WI-3 #830 gated head) is **not on origin** — it exists only as a local

-> (`stack-cr-wi3-revoke`, HEAD == `f4008307`) rather than passing over a clone-completeness gap. The
-> broker pin was recomputed from origin `23c0caca`.
-
-## Findings — VERDICT: byte-scope + mechanism + hygiene **PASS** (v7 full-closure bar)
-
-Homelab's stricter bar — **hashed==executed on the FULL executed closure (launcher + helper + broker)**
-— is met. Verified at the source, not accepted on the review's assertion:
-
-**B5 conjunction (the load-bearing repair) — HELD, all three legs:**
-- **(a) materialized from pinned git-object bytes, NOT the mutable worktree.** `materialize_closure`
-  fetches each member via `git_object_bytes` (`git show {commit}:{path}`), then
-  `sha256(data) == pin` **fail-closed** (`RuntimeError` on mismatch) before use.
-- **(b) no writable window hash→consume.** `pinned/` is `mkdir(mode=0o700)`; each file is written with
-  `os.open(O_WRONLY|O_CREAT|O_EXCL|O_CLOEXEC, 0o600)` — `O_EXCL` refuses a pre-planted file. No `chmod`,
-  no `os.rename/replace`, no `symlink`, and nothing re-opens a pinned file for write (grep = 0). The
-  pinned bytes are immutable within the fixture threat model between hash and exec.
-- **(c) re-hash == pin IMMEDIATELY before each exec, no interleaved yield.** Launcher: re-hash then
-  `return PiRpc(command,…)` whose `__init__` **first statement** is `subprocess.Popen(command,…)` —
-  zero IO/yield/reopen between. Broker + helper: both re-hashed then `subprocess.Popen` on the next
-  line. Adjacency-alone-without-materialization (the v6 defect) is **absent** — all three exec from
-  `pinned/`.
-
-**B6 — helper pinned AND bound to the SAME single copy.** The broker receives
-`--generation-module {closure.generation}` (the pinned helper); the launcher runs from `pinned/` so its
-`import lease_generation` resolves to the sibling pinned copy via `sys.path[0]`. `closure_import_guard`
-AST-parses every member and raises on any non-stdlib import other than the allowed `lease_generation`
-— proving the dependency closure is complete and no unpinned module can enter at runtime.
-
-**Closure = exactly 3 files, materialized inside the fixture root** (`root / "pinned"`). No path escapes
-the fixture temp root; no live/default broker; `.state` remains fixture-bound. **R1 owner tripwire NOT
-tripped** — this deepened isolation of an already-authorized touch, it did not widen the touched surface.
-
-**Invariants (all INTACT):** BAR1 `GATED_WI_HEAD == f4008307` and `merge-base --is-ancestor 66b1e0a0
-f4008307` = YES (file-backed `.state` revocation fidelity present); BAR2 `.state` =

-the only `shutil.copy2` is the legitimate `.pi/agent` credential copy (settings/auth/fd), **not** a
-launcher/helper/broker copy — the v6 copy-to-fixture concern is gone.

----
-
-## ⚠️ SUPERSEDED — homelab v7 third-principal FAIL @f609a449 raised a stricter bar (evidence-integrity note)
-
-This co-attestation was **byte-clear on the v7 full-closure bar ONLY** and self-limited above to
-*"byte-clear NOT fire-authorization; FIRE remains gated on homelab third-principal re-verify."*
-Homelab (the required third principal) subsequently returned **FAIL @f609a449** (static verify, no
-code run), and Mos **UPHELD** it after independently confirming both findings in source — so the v7
-byte-clear this document records is **SUPERSEDED** and does **NOT** authorize FIRE.
-
-Two residual isolation/binding holes WITHIN the materialized closure (both independently reproduced
-by Mos in the harness source; accepted as gate-**strengthening**, not softening):
-1. **Broker child env not isolated.** `launch_verified_broker` (`:551`) calls `Popen` with **no
-   `env=`** (only `PiRpc.__init__` `:50` passes an allow-listed `env`) → the broker child inherits
-   ambient `os.environ` (PYTHONPATH/PYTHONHOME/PYTHONPYCACHEPREFIX). `closure_import_guard` is a
-   static AST check and cannot bind the child's runtime stdlib resolution.
-2. **Executed bytecode-cache outside the pin.** No `PYTHONDONTWRITEBYTECODE`/`-I`/`-B`/`__pycache__`
-   handling anywhere. `exec_module` on the pinned helper writes derived `.pyc` the pin never covers;
-   only the `.py` is re-hashed → executed bytecode ≠ pinned-source-hash.
-
-Both break "hashed==executed on the FULL executed closure" on **fidelity** grounds even in a
-non-adversarial fixture. Mos **authorized the bounded repair** (broker `Popen` with strict
-allow-listed `env=` + `-I` + `PYTHON*` stripped; bytecode-cache suppressed via
-`PYTHONDONTWRITEBYTECODE=1`/`-B` + reject stray `__pycache__`/`.pyc` fail-closed before each
-consumer; launcher sibling-import binding to the pinned helper preserved). This **rides the existing
-(ii)-full-closure authorization + R1 + Mos adjudication** — it deepens isolation/binding of an
-already-authorized touch, stays inside the fixture temp root, no fresh Jason owner-window. It is
-**NOT a Case-C escalation** (no probe fired, no evidence produced — a static pre-fire catch, exactly
-what the review gate is for). Added review bars **B7** (broker child env-isolated) and **B8**
-(executed bytecode pinned-or-suppressed) on top of B5+B6+all priors.
-
-**Live target = v8** (env-isolated + bytecode-pinned harness, forthcoming). `f609a449` /
-`2bba933f` / this co-attestation (`e08ad03`) are **SUPERSEDED**. A fresh Mos co-attestation will be
-committed on v8 byte-verify PASS. WI-3 #830 remains HELD at `f4008307`; nothing banked; C-hatch

-This SUPERSEDES the v7 co-attestation `e08ad03` (and its SUPERSEDED note `2ae379e`), which was
-byte-clear on the v7 bar and was overtaken by homelab's third-principal FAIL @f609a449 (broker
-env-isolation + executed-bytecode-cache) and the resulting B7/B8 bar.

-
-## Findings — VERDICT: byte-scope + mechanism + hygiene **PASS** (v9 = v7 full-closure + B7 + B8)
-
-The v7→v9 delta is **exactly 22 insertions / 2 deletions**, confined to the intended B7+B8+B6c
-surface; every prior invariant is byte-stable (outside the delta) from the v7 verify.
-
-**B7 — broker child env-ISOLATED (homelab finding 1 CLOSED).** `launch_verified_broker` (`:568`) now
-passes `env=environment` (the strict allow-list, `:570`) — the ambient-`os.environ`-inheritance hole
-is gone — AND runs the broker with `-I` (`:552`, isolated: ignores `PYTHON*`/user-site) + `-B`
-(`:553`). Both children are env-controlled: the launcher was already `env=env` at `PiRpc` (`:53`).
-
-**B8 — executed bytecode PINNED/SUPPRESSED (homelab finding 2 CLOSED).** `reject_pinned_bytecode`
-(`:498`) raises `RuntimeError` fail-closed if a `__pycache__` dir or any `*.pyc` exists in the pinned
-dir, and is called before **each** consumer (launcher `:535`, broker `:562`). Bytecode writes are
-disabled via `PYTHONDONTWRITEBYTECODE=1` (`:729`) in the allow-list env **and** `-B` on both command
-lines. No unpinned `.pyc` can be executed; only the pinned `.py` re-hash governs.
-
-**B6c — launcher sibling-import PRESERVED (v8 regression FIXED).** v8 over-applied `-I` to the
-launcher; on Py3.11+ `-I` implies `-P`, dropping the script dir from `sys.path[0]`, so the pinned
-launcher's bare `from lease_generation import` (launch-runtime.py:15) would `ModuleNotFoundError`. v9
-uses `-s` (`:514`) + `-B` (`:515`) on the launcher (NO `-I`) — neither touches `sys.path[0]`, so the
-sibling import still resolves to `pinned/lease_generation.py`. **Mos empirically re-verified on host
-Py3.11.2** (throwaway, not the harness): `-I` launcher → `ModuleNotFoundError`; `-s`+`PYTHONNOUSERSITE`
-→ import OK. The launcher's env isolation comes from the `PiRpc` `env=` allow-list, NOT `-I`, so
-dropping `-I` does **not** reopen B7. My earlier constraint-(c) assumption ("`-I` does not strip the
-script dir") was FALSIFIED for 3.11+; the author≠reviewer gate (ms-secrev-828) caught it — recorded.
-
-**B5 conjunction (load-bearing repair) — HELD, all three legs (byte-stable from v7):**
-(a) materialized from pinned git-object bytes via `materialize_closure`/`git_object_bytes`, `sha256==pin`
-fail-closed; (b) `pinned/` `mkdir(0o700)` + `O_EXCL|O_CLOEXEC` `0o600`, no writable window — now also
-`reject_pinned_bytecode` closes the `.pyc` side-channel; (c) re-hash == pin IMMEDIATELY before each
-exec, no interleaved yield: launcher re-hash (`:538`) → `return PiRpc(command,…)` whose `__init__`
-first statement is `Popen` (`:50`); broker re-hash (`:563`) + helper re-hash (`:566`) → `Popen`
-(`:568`) on the next line.
-
-**B6 — single pinned helper, complete closure.** Broker gets `--generation-module {closure.generation}`;
-launcher resolves `import lease_generation` to the sibling pinned copy via `sys.path[0]`.
-`closure_import_guard` (`:351`, called `:433`) AST-rejects any non-stdlib import other than
-`lease_generation`. Single broker: `launch_verified_broker` 1 def (`:543`) + 1 call (`:766`).
-
-**Invariants (all INTACT):** BAR1 `GATED_WI_HEAD == f4008307` (`:36`) and `merge-base --is-ancestor
-66b1e0a0 f4008307` = YES (file-backed `.state` revocation fidelity present); fidelity
-`generation_source=='state-file'` (`:639`), `state_file_in_fixture_root` (`:641`),
-`MUTATOR_UNVERIFIED` (`:650`), `STALE_GENERATION` (`:651`); `lease_anchor_registered` (`:593`);
-`-O`-safe (0 bare `assert`); `--runs choices=(3,)` (`:838`); allow-list env (0 `os.environ.copy`);
-ABSENT-sweep (`yolo`/`execRuntime`/`p3_bank`/`promote_p2`/`retry`) = 0; the only `shutil.copy2`
-(`:708`) is the `.pi/agent` credential copy, not a closure copy.
-
-**Closure = exactly 3 files, materialized inside the fixture root.** No path escapes the fixture temp
-root; no live/default broker; `.state` fixture-bound. **R1 owner tripwire NOT tripped** — B7/B8
-deepen isolation/binding of an already-authorized touch, they do not widen the touched surface.
-
-## Independence
-
-Substantive principal-independence of review-v9 is satisfied by an orchestrator-dispatched,
-builder-distinct Opus SECREV (`ms-secrev-828`, byte-only, non-builder, non-Mos). The shared
-`ms-lead-reviewer` git signer on harness+review commits is evidentiary, not substantive — resolved by
-(1) this Mos co-attestation under a **distinct** identity (`mos-orchestrator`) and (2) a homelab
-third-principal verify under its own distinct identity = three distinct-identity principals of record.
-Shared signer = tracked fleet-infra tooling-gap (durable fix = per-lane distinct signers), not a blocker.
-
-## Scope of this record — byte-clear, NOT fire-authorization
-
-Producing probe evidence **executes** the Gate0 mechanism; a byte-clear is not a fire-authorization.
-This clears **bytes / scope / mechanism / hygiene on the v9 (full-closure + B7 + B8) bar**. FIRE
-remains gated on: **homelab third-principal re-verify** (4th round, own distinct identity) + **Mos
-transparency-to-Jason** + **Mos explicit FIRE GO**. Until then: nothing banked, WI-3 #830 held at
-`f4008307` (unmoved), C-hatch armed (materialized-closure rig still no-fire / wrong-value /
-assertion-FAIL / isolation-FAIL → possible Case-C → STOP + escalate to Jason).
-
-**Mos verdict: v9 full-closure + B7 + B8 byte-scope + mechanism + hygiene PASS. Co-attestation of
-record — committed.**
-
----
-
-## ⚠️ SUPERSEDED — homelab v9 4th-round FAIL @1c34e3cb raised a stricter *startup-closure* bar
-
-This co-attestation was **byte-clear on the v9 (env-iso + bytecode-pin) bar ONLY** and self-limited
-above to *"byte-clear NOT fire-authorization; FIRE remains gated on homelab 4th-round re-verify."*
-Homelab (the required third principal) returned **FAIL @1c34e3cb** (static, nothing executed), and Mos
-**UPHELD** it after independently confirming the finding in-source AND empirically on host Py3.11.2 —
-so the v9 byte-clear this document records is **SUPERSEDED** and does **NOT** authorize FIRE.
-
-**Residual startup-closure hole (empirically reproduced by Mos; accepted as gate-STRENGTHENING):**
-neither child carries `-S`, so CPython imports the `site` module **before** the script runs. `-s`
-(launcher) suppresses only *user*-site; `-I` (broker) implies `-s -E -P` but **NOT** `-S`. Proven:
-
-    [-s  -B ]  no_site=0  site_imported=True    ← v9 launcher: site runs
-    [-I  -B ]  no_site=0  site_imported=True    ← v9 broker: -I does NOT imply -S
-    [-s -S -B] no_site=1  site_imported=False   ← v10 launcher fix (sibling import STILL resolves)
-    [-I -S -B] no_site=1  site_imported=False   ← v10 broker fix (additive)
-
-System-site executable `.pth` lines + sitecustomize/usercustomize can therefore run **unpinned startup
-code** before the exact launcher/broker and **outside** `closure_import_guard`, while every hash +
-`reject_pinned_bytecode` + import-guard still pass — defeating hashed==executed on the full *startup*
-closure (strictly wider than the module-import closure v9 cleared). A genuine fidelity hole for a
-fail-closed DO-178C evidence gate.
-
-Mos **authorized the bounded v10 repair**: add `-S` to the **launcher** (keep `-s -B`, NOT `-I`) and
-to the **broker** (keep `-I -B`) — a minimal 2-line delta; no B6c regression (launcher `-s -S -B`
-sibling import empirically intact; `-S` does not touch `sys.path[0]`). Added review bar **B9**
-(no-site startup closure). This **rides the existing (ii)-full-closure authorization + R1 + Mos
-adjudication** (deepens startup-closure isolation of an already-authorized touch, inside the fixture
-temp root, no fresh Jason owner-window) and is **NOT a Case-C escalation** (static pre-fire catch, no
-probe fired). A separate **FIRE-time** constraint is captured: the 3× isolation dispatch must launch
-the runner under externally-enforced `python -I -S -B` (a self-reexec is too late).
-
-**Live target = v10** (no-site harness, forthcoming). `1c34e3cb` / `e1c9a468` / this co-attestation
-(`f320d075`) are **SUPERSEDED**; the prior 2-of-3 (ms-secrev-828 v9 §3 PASS + `f320d075`) does NOT
-carry — all three distinct-identity principals re-verify the new v10 SHA. A fresh Mos co-attestation
-will be committed on v10 byte-verify PASS. WI-3 #830 remains HELD at `f4008307`; nothing banked;
-C-hatch armed (fired-rig only); NO FIRE.

-## Principal-independence attestation (Mos independence ruling — process of record)
-
-This review is produced by a **distinct Opus SECREV session, orchestrator-dispatched** — the **`ms-secrev-828`
-reviewer lane, dispatched by `mosaic-100`** — **byte review only, ran nothing**, and **did NOT build** this harness
-(builder = ms-rev-826). Author ≠ reviewer (Gate-16). This is one of three principals: **Mos commits his own
-distinct-identity byte-scope-verify co-attestation at v-final**, and **homelab's independent verify is the third
-principal**. (The `ms-lead-reviewer` **Git signer identity** shared across published review commits is a git-signer
-question routed to Mos; it does not bear on this lane's process/dispatch independence, attested here.)
-
-## NEW-5 CLOSED — approach (i): exact-byte pin, adjacent re-hash, exec in place
-
-- **Exact-byte sha256 is the trust anchor, NOT substring heuristics.** Launcher bytes are read from the immutable
-  git object (`git show f4008307:<path>`) and gated on `sha256(launcher_bytes) == GATED_LAUNCHER_SHA256`
-  (`e950e422…`) (:354). The `behavior_markers` `in`-checks (:364-372) are explicitly commented "the exact launcher
-  digest above is the trust anchor. These marker checks are diagnostic belt-and-suspenders only, never a substitute
-  for the pin" (:362-363). The old ordered `.find()` heuristic (`register < initialize < execute`, min<0) is **gone**.
-- **Final re-hash immediately adjacent to `Popen`, no interleaved yield.** `launch_verified_pi` assembles `command`,
-  then — as the statement **immediately before** `return PiRpc(command, …)` (which performs the `Popen`) — re-hashes
-  the launcher: `if hashlib.sha256(launcher.read_bytes()).hexdigest() != GATED_LAUNCHER_SHA256: raise` (:411-412),
-  `return PiRpc(...)` (:413). **No harness-controlled step (no `wait_path`, no broker spawn) sits between the re-hash
-  and the exec** — the broker `Popen` + `wait_path` occur *before* `launch_verified_pi` is called (:611-621). Window
-  narrowed to the fork/exec itself.
-- **Exec stays IN PLACE at the pinned f4008307-worktree path.** The precondition returns the worktree paths
-  `gated_root / launcher_relative`, `gated_root / generation_relative` (:378); Pi execs `str(launcher)` = that
-  worktree launch-runtime.py (:390,:621), and the broker `--generation-module` = the worktree lease_generation.py
-  (:614). The reverted (ii) machinery is **gone**: `grep pinned-lease-broker / PYTHONPATH / fixture_launcher /
-  fixture_generation / write_bytes == 0`. Launcher import resolution and the file-backed fidelity surface are
-  therefore **unperturbed** (this is the lower-risk approach Mos mandated over copy-to-fixture).
-
-## NEW-6 CLOSED — portable, validated, off-by-one gone
-
-`GATED_WI_ROOT` is no longer the off-by-one `HERE.parents[3].parent / "stack-cr-wi3-revoke"`. It is resolved by
-`resolve_gated_wi_root()` (:257-307): an explicit `GATED_WI_ROOT` env override, else **repo-relative** `git worktree
-list --porcelain` (from `repository_root()`, first parent containing `.git`) selecting the **unique** worktree whose
-`HEAD == f4008307` **and** `branch == refs/heads/feat/830-compaction-revoke` (raise if ambiguous/absent). It then
-**fail-closes** unless `gated_root.is_dir()`, `git rev-parse --is-inside-work-tree == "true"` (:304-305), and
-`HEAD == GATED_WI_HEAD` (:306-307). Independently recomputed on this host (git query, harness not run): it resolves
-to the real worktree **`/home/hermes/agent-work/stack-cr-wi3-revoke`**. Portable + validated; the off-by-one is gone.
-
-## Full v4/v5 carry-over re-sweep (byte-stable vs `7f975b95` except the NEW-5/6 delta)
-
-`diff 7f975b95 → 2d54a9dd` confines changes to launcher resolution (NEW-6) + adjacent-rehash-exec-in-place (NEW-5);
-nothing else moved. Re-swept intact: **creds-scrub** (`scrub_fixture_credentials` + outermost `finally`); **`source-invalid`
-ABSENT** (grep=0 both files); **fidelity file-backed** unperturbed (broker `read_runtime_generation`/`bump_runtime_generation`
-on the fixture `.state`; `assert_d4` `generation_source=="state-file"` + `state_file_drives_lifecycle` +
-`state_file_in_fixture_root` + `new→MUTATOR_UNVERIFIED`/`prior→STALE_GENERATION`); **`lease_anchor_registered`** INTACT
-(event + `hex-256`); **live-path** gated launcher; **fail-closed precondition**; **fixture-socket isolation**; **`-O`-safe**
-(0 bare `assert`, PASS derived); **allow-list env** (0 `os.environ.copy`); **`--runs choices=(3,)`**; **single p3 broker**
-(broker byte-identical to v5). **ABSENT sweep = 0** (P5/P6/P2-bank/retry-launder/mosaic-yolo/execRuntime/pi_gate0/run_open/
-atomic; extension actions only bump/lifecycle/authorize/promote; no exec-at-import). **Beyond-R1 tripwire: not tripped** —
-exec is in place, imports and the file-backed observation surface untouched; no isolation crossing.
-
-## Verdict
-
-**PASS @ `2d54a9dd`.** NEW-5 (approach (i): exact-byte sha256 pin as trust anchor; adjacent re-hash immediately
-before `Popen` with no interleaved yield; exec in place at the pinned f4008307-worktree path; (ii) copy-to-fixture/
-PYTHONPATH machinery reverted) and NEW-6 (portable, validated, off-by-one-gone root resolution) are both **closed**;
-the full v4/v5 carry-over holds byte-stable except the two intended surfaces; ABSENT sweep is 0; the R1 file-backed
-fidelity surface is unperturbed. Zero out-of-scope surface.

-## Independence (GUARD 2 — principal-independence attestation)
-
-Distinct Opus SECREV session, orchestrator-dispatched — the **`ms-secrev-828` reviewer lane, dispatched by
-`mosaic-100`** — **byte review only, ran nothing** (harness/broker not executed); did **not** build this harness
-(builder = ms-rev-826); is not Mos; distinct principal from both. This re-verifies from scratch on the v10 SHA after
-homelab's 4th-round FAIL @`1c34e3cb` (no `-S` → `site` startup-closure hole) superseded my v9 PASS + Mos's co-attest.
-The `-S`/`-s`/`-I` behavior checks below use a *throwaway* script to observe interpreter startup — not the harness.
-
-## ★ B9 — No-site startup closure (the homelab 4th-round FAIL)
-
-The delta vs `1c34e3cb` is **exactly two `-S` insertions**, byte-confirmed by `diff` (nothing else; +28 B fully
-accounted by the two `        "-S",\n` lines):
-
-- **(i) Launcher command** (`launch_verified_pi`, :512-516): `sys.executable, "-s", "-S", "-B", str(launcher), …` —
-  carries `-s` + **`-S`** + `-B`, and **no `-I`**.
-- **(ii) Broker command** (`launch_verified_broker`, :551-554): `sys.executable, "-I", "-S", "-B", str(broker_path), …`
-  — carries `-I` + **`-S`** + `-B`.
-- **(iii) `site` not imported at child startup** — empirically confirmed (Python 3.11.2, throwaway script):
-  `python3 -s -S -B main.py` → `sys.flags.no_site == 1`, `'site' in sys.modules == False`; `python3 -I -S -B main.py`
-  → `no_site == 1`. So system-site `.pth` executable lines and `sitecustomize`/`usercustomize` **cannot run unpinned
-  startup code** before the pinned launcher/broker. (Contrast without `-S`: `python3 -s -B` → `no_site == 0`, `site`
-  imported — the exact v9 hole this closes.)
-- **(iv)** No harness reliance on any site-injected path/hook (env is the constructed allow-list; children execute
-  pinned bytes).
-- **(v) `-S` does not touch `sys.path[0]`** (unlike `-I`/`-P`) — empirically confirmed: `python3 -s -S -B main.py`
-  keeps `sys.path[0]` = the script's directory, so the launcher's bare `from lease_generation import
-  initialize_runtime_generation` (`f4008307:launch-runtime.py:15`) **still binds `pinned/lease_generation.py`** with
-  `-S` present. The broker's explicit `--generation-module` import (via `importlib`) binds the pinned helper
-  regardless of `sys.path`/site, so `-I -S` is correct there.
-- **(vi) Delta = exact 2-line `-S` only** vs `1c34e3cb` (git-diff/byte-compared, not accepted on assertion).
-
-## All prior bars — byte-stable (delta was only the two `-S` lines)
-
-- **B6(c):** launcher still carries no `-I`; sibling import binds `pinned/` (confirmed above with `-S` present). ✅
-- **B7:** broker `Popen` `env=environment` (allow-list, **not** `os.environ`; no `PYTHONPATH`/`PYTHONHOME`/
-  `PYTHONPYCACHEPREFIX`) + `-I`. ✅
-- **B8:** `reject_pinned_bytecode` fail-closed before each consumer; `PYTHONDONTWRITEBYTECODE=1` + `PYTHONNOUSERSITE=1`
-  in env; `-B` on both children. ✅
-- **B5:** 3-leg conjunction — materialize each of launcher/helper/broker from git-object bytes with `sha256==pin`
-  fail-closed; `pinned/` `0o700` in fixture root, files `O_EXCL 0o600` (no writable window); re-hash `==pin`
-  immediately before each `Popen`; launcher + broker consume the same single pinned helper. ✅
-- **B6:** `closure_import_guard` AST present; single pinned helper; broker `--generation-module = closure.generation`. ✅
-- **Fidelity:** extension bumps `generation-{sid}.state` via `MOSAIC_LEASE_GENERATION_FILE` (not in-mem); broker
-  `read_runtime_generation`; `assert_d4` `generation_source=="state-file"` / `state_file_in_fixture_root` /
-  `new→MUTATOR_UNVERIFIED` / `prior→STALE_GENERATION`; `.state` fixture-root-bound. ✅
-- **Traceability:** `GATED_WI_HEAD == f4008307` + `merge-base --is-ancestor 66b1e0a0 f4008307`. ✅
-- `lease_anchor_registered` + `hex-256` INTACT; LIVE-PATH (pinned gated launcher); single p3 broker;

-## Independence (GUARD 2 — principal-independence attestation)
-
-This review is produced by a **distinct Opus SECREV session, orchestrator-dispatched — the `ms-secrev-828`
-reviewer lane, dispatched by `mosaic-100`** — **byte review only, ran nothing**, that **did NOT build** this harness
-(builder = ms-rev-826) and **is not Mos**. Three distinct principals: this reviewer, the builder, and Mos (whose
-own distinct-identity byte-scope-verify follows); homelab's independent verify is a further principal — it is
-homelab's third-principal FAIL @`2d54a9dd` (upheld by Mos) that correctly retired the approach-(i) adjacency
-re-hash and authorized this full-closure. v6/`2d54a9dd`/`23c0caca`/`12914d8` are superseded.
-
-## Why v7 (the reopen-after-hash hole)
-
-Approach (i) re-hashed the launcher then let `Popen` **reopen the worktree path** — hashed-snapshot ≠ executed-bytes
-(the worktree file is a shared, same-UID-mutable path). Statement adjacency alone did not bind. v7 closes it for the
-**full project-code closure** (launcher + `lease_generation.py` helper + `p3_generation_broker.py`).
-
-## B5 — HASHED == EXECUTED on the full closure (binding conjunction, stated verbatim)
-
-The reopen-after-hash shape is unavoidable for imported/exec'd files, so closure rests on the **conjunction of all
-three legs**, each byte-verified here:
-
-> **(a)** bytes are materialized **from the pinned git-object @ `f4008307`** (helper/launcher) and **@ `23c0caca`**
-> (broker) — `git show <commit>:<path>`, the trusted immutable object, **never the mutable worktree file**; **AND**
-> **(b)** into a **fixture-private `0o700` dir with `0o600` files created via `O_CREAT|O_EXCL`** — no writer exists in
-> the threat model between hash and exec; **AND** **(c)** each member is **re-hashed == its pin IMMEDIATELY before
-> exec/import, fail-closed (`RuntimeError`)**.
-
-Byte evidence:
-- **(a)** `git_object_bytes(git_root, commit, relative)` = `git show <commit>:<path>` (:322-327); `materialize_closure`
-  reads all three members from git objects and asserts `sha256(data) == digest` else `RuntimeError` (:415-433). Worktree
-  working-tree files are never read.
-- **(b)** `pinned = root / "pinned"; pinned.mkdir(mode=0o700)` (:435-436); `write_pinned_file` uses
-  `os.open(path, O_WRONLY|O_CREAT|O_EXCL|O_CLOEXEC, 0o600)` (:379-382). **No `os.chmod`/`os.rename`/`shutil.move`
-  anywhere** (grep=0); `O_EXCL` refuses a pre-planted file/symlink, so no symlink-follow or hijack gap; the dir is a
-  fresh per-run `mkdtemp` child, owner-only. **No code re-opens the pinned files for write between materialize and
-  consume** — there is no writable window.
-- **(c)** launcher re-hash `sha256(launcher.read_bytes()) == GATED_LAUNCHER_SHA256` is the statement immediately before
-  `return PiRpc(command,…)` (:528-530); broker **and** helper re-hashes (`== GATED_BROKER_SHA256`,
-  `== GATED_GENERATION_SHA256`) are the two statements immediately before `return subprocess.Popen(command,…)`
-  (:546-551). No interleaved harness yield.
-
-Adjacency-only exec-from-worktree is **absent** for every member (all three exec/import from `pinned/`; grep worktree-exec=0).
-
-## B6 — helper + broker pinned and bound to execution (one shared helper)
-
-`materialize_closure` writes exactly **one** `pinned/lease_generation.py` (:442). The broker executes the **pinned**
-broker with `--generation-module = closure.generation` = that pinned helper (`launch_verified_broker`, :533-551, called
-:746-747). The launcher executes the **pinned** launcher (`python3 pinned/launch-runtime.py`), whose
-`import lease_generation` resolves via `sys.path[0]` = the script's own `pinned/` dir to the **same** sibling
-`pinned/lease_generation.py`. Launcher-import and broker-`--generation-module` therefore resolve the **same single
-pinned helper copy**, not two copies and not the worktree. Worktree helper/broker are not re-read at runtime.
-
-**Closure-import guard:** `closure_import_guard` AST-parses each member and refuses any non-stdlib import outside the
-allow-set `{"lease_generation"}` (and any relative import) → `RuntimeError` (:341-364). The 3-member closure is
-therefore provably complete — no unpinned project-code dependency can slip in.
-
-## BAR1 — Traceability
-
-`GATED_WI_HEAD == f4008307`; the precondition asserts `git merge-base --is-ancestor 66b1e0a0 f4008307` (:315-330),
-independently confirmed **YES** — the pinned launcher forward-contains the `66b1e0a0` file-backed generation mechanism.
-
-## BAR2 — Fidelity file-backed, `.state` in fixture root, UNTOUCHED
-
-`pinned/` holds **code bytes only** (launcher/helper/broker). The `.state` generation file is written by the launcher
-to `socket_path.parent` (the fixture root), **not** `pinned/`. The broker (pinned, byte-identical `4db4fef1`) still
-enforces `generation_environment` raising if `state_path.parent != socket_path.parent` (grep=2), and `assert_d4`
-still checks `state_file_source == "state-file"` / `state_file_drives_lifecycle` / `state_file_in_fixture_root` +
-`new→MUTATOR_UNVERIFIED` / `prior→STALE_GENERATION` (grep=4, unchanged). The v7 change did not move `.state` into
-`pinned/` or perturb these asserts.
-
-## BAR3 — Carry-over
-
-(a) **live-path:** Pi launched via `python3 pinned/launch-runtime.py --runtime pi -- pi …` (gated register-before-exec);
-`mosaic yolo`/`execRuntime` = 0. (b) **fail-closed precondition:** `gated_launcher_precondition` (resolve+materialize+
-verify) runs before any launch, fail-closed. (c) **fixture-socket isolation:** `MOSAIC_LEASE_BROKER_SOCKET` = per-run
-fixture socket; single pinned p3 broker serves `register_anchor`; no live/default broker reachable; non-destructive.
-(d) **`lease_anchor_registered` INTACT:** event + `session_id_shape=="hex-256"` unchanged (broker byte-identical);
-`assert_d4` folds it into the single-identity set — not deleted/softened/optional/repointed.
-
-## Re-confirm + ABSENT sweep
-
-Spawns ONLY the single pinned p3 broker; promotion=fixture-only; full D4 asserts; `--runs choices=(3,)`; allow-list
-env (0 `os.environ.copy`); **`-O`-safe** (all new checks `RuntimeError`, **0 bare `assert`**); creds-scrub intact;
-non-destructive (fixture tempdir only); deterministic (git objects + fixed pins); closure-import guard present.
-**ABSENT = 0:** P5/P6/P2-bank/retry-launder/mosaic-yolo/execRuntime/pi_gate0; `source-invalid` grep=0; no live/real-broker
-path; no `.state`/gen path outside the fixture root; no extra broker/socket; no exec-at-import (`__main__`-guarded); no
-adjacency-only exec-from-worktree for any member; the only mechanism change is materialization; no scope-widen.
-
-## Verdict
-
-**PASS @ `f609a449`.** B5 (full-closure hashed==executed via the (a)+(b)+(c) conjunction with no writable window),
-B6 (one shared pinned helper bound to both launcher-import and broker-`--generation-module`; complete closure), BAR1,
-BAR2 (fidelity `.state`-in-fixture-root untouched), and BAR3 all hold, with zero out-of-scope surface. **Findings: none.**

-## Independence (GUARD 2 — principal-independence attestation)
-
-Distinct Opus SECREV session, orchestrator-dispatched — the **`ms-secrev-828` reviewer lane, dispatched by
-`mosaic-100`** — **byte review only, ran nothing** (the harness/broker were not executed); did **not** build this
-harness (builder = ms-rev-826); is not Mos. This verdict is my own. (The `-I` semantics check below runs a *throwaway*
-two-line script to observe the interpreter's `sys.path` behavior — it does not run the harness, broker, or any part of
-the reviewed closure.)
-
-## 🔴 BLOCKING FINDING — B6(c) broken: `-I` on the launcher strips the pinned-helper import path
-
-**File:line — `p3_d4_focused_run.py:512`** (the `"-I"` added to `launch_verified_pi`'s launcher command).
-
-The pinned launcher `launch-runtime.py` @`f4008307` imports its helper with a **bare top-level import**:
-`from lease_generation import initialize_runtime_generation` (launcher line 15) — no `sys.path` manipulation. Under
-v7 this bound because `python3 pinned/launch-runtime.py` put the script's directory (`pinned/`) at `sys.path[0]`, so
-the sibling `lease_generation` resolved to `pinned/lease_generation.py`.
-
-v8 now runs the launcher as `python3 -I -B pinned/launch-runtime.py …` (:512-513). **`-I` implies `-P` (Python 3.11+),
-which does NOT prepend the script's directory to `sys.path`.** Empirically confirmed on this host (Python 3.11.2),
-using a throwaway script (not the harness):
-
-```
-python3 -I -B main.py  → sys.path[0] = '/usr/lib/python311.zip'
-                          import sibling → ModuleNotFoundError: No module named '…'
-python3    -B main.py  → sys.path[0] = '<script dir>'  → sibling import: OK
-```
-
-Therefore, at FIRE on Python 3.11+, the launcher's line-15 `from lease_generation import …` raises
-`ModuleNotFoundError` at module load — the pinned helper does **not** resolve (neither pinned nor worktree; the import
-simply fails). **B6(c) — "launcher sibling-import to `pinned/` via `sys.path[0]` STILL BINDS" — does not hold.** The
-build report's assertion "`-I` keeps script dir" is false on 3.11+, and could not have been observed under the
-correct "never run" boundary.
-
-Note: the env allow-list carries no `PYTHONPATH` (correct for B7), and `-I` ignores `PYTHON*` env regardless, so there
-is no alternate resolution path — the launcher import is unrecoverable under `-I`.
-
-**Fix:** remove `-I` from the **launcher** command only (keep `-B` + the `env=` allow-list — the launcher's
-env-isolation is already provided by the constructed allow-list, which contains no `PYTHONPATH`/`PYTHONHOME`/
-`PYTHONPYCACHEPREFIX`, and it needs `pinned/` at `sys.path[0]` for the sibling import). Keep `-I` on the **broker**
-command (it loads the helper by explicit `--generation-module` path via `importlib`, so it never needs the script
-dir on `sys.path`). Alternatively, inject the pinned dir explicitly (e.g. `PYTHONPATH=pinned/` — but that reintroduces
-a `PYTHON*` passthrough B7 forbids, so dropping `-I` on the launcher is the clean fix).
-
-## What DID land correctly (for the author's fast turnaround)
-
-- **B7 — broker child env-isolated: correct.** `launch_verified_broker` now takes `environment` and passes
-  `env=environment` (the constructed allow-list, **not** `os.environ`) to `Popen` (:566-568); the broker command
-  includes `-I` (:551); the allow-list contains no `PYTHONPATH`/`PYTHONHOME`/`PYTHONPYCACHEPREFIX` passthrough. The
-  broker child cannot inherit ambient env or resolve stdlib imports to ambient code. ✅
-- **B8 — bytecode pinned-or-suppressed: correct.** `PYTHONDONTWRITEBYTECODE=1` is in the allow-list env (:728) and
-  `-B` is on **both** child commands (:512-513 launcher, :551-552 broker); `reject_pinned_bytecode` fails closed
-  (`RuntimeError`) on any pre-existing `pinned/__pycache__` or `*.pyc` (:498-501) and is called **before each
-  consumer** (:534 launcher, :561 broker). No unpinned `.pyc` can be executed. ✅
-- **B5 conjunction / B6 single-helper / closure-import-guard / BAR1 / BAR2 (`.state` fidelity untouched) / BAR3
-  (live-path, fail-closed precondition, fixture-socket isolation, `lease_anchor_registered` + hex-256) / single p3
-  broker / `-O`-safe / allow-list env / `--runs==(3,)` / ABSENT sweep:** all intact/unperturbed (the delta touches only
-  the env/`-I`/`-B`/bytecode-reject surfaces). These are **not** the failing item.
-
-## Verdict
-
-**FAIL @ `a92ad090`.** B7 (broker env isolation) and B8 (bytecode pinned-or-suppressed) are correctly implemented,
-but the `-I` added to the **launcher** command breaks B6(c): the launcher's bare `from lease_generation import` at
-`f4008307:launch-runtime.py:15` cannot resolve the pinned helper because `-I`/`-P` strips `sys.path[0]` on Python
-3.11+ (empirically confirmed, 3.11.2 → `ModuleNotFoundError`). PASS requires **all** of B7+B8+B5+B6+BAR1/2/3; B6(c)
-does not hold. Not softened → returns to author (ms-rev-826). The fix is narrow: drop `-I` from the launcher command
-(retain `-B` + allow-list env), keep `-I` on the broker.
-
-**Findings:** B6(c) — `p3_d4_focused_run.py:512` (`-I` on the launcher command; breaks the pinned-helper sibling

-## Independence (GUARD 2 — principal-independence attestation)
-
-Distinct Opus SECREV session, orchestrator-dispatched — the **`ms-secrev-828` reviewer lane, dispatched by
-`mosaic-100`** — **byte review only, ran nothing** (harness/broker not executed); did **not** build this harness
-(builder = ms-rev-826); is not Mos. This is the re-review after **my own** v8 FAIL @`a92ad090` (B6(c): `-I` on the
-launcher broke the sibling import); the author applied the narrow fix and I verify it here. The `-s`/`-I` `sys.path`
-checks below use a *throwaway* two-line script to observe interpreter behavior — not the harness/broker/closure.
-
-## ★ B6(c) — THE FIX (was the v8 FAIL): launcher `-I` dropped; sibling import binds to `pinned/`
-
-The launcher command no longer carries `-I`; it now uses **`-s`** (`:514`, commented "`-s` preserves `sys.path[0]=pinned/`
-for the launcher's sibling helper") + `-B` (`:515`), and `PYTHONNOUSERSITE=1` is added to the allow-list env (`:730`).
-
-`-s` and `PYTHONNOUSERSITE` disable **user site-packages only** — they do **not** strip the script's directory from
-`sys.path` (unlike `-I`/`-P`). Empirically confirmed on this host (Python 3.11.2), throwaway script:
-
-```
-python3 -s -B main.py                       → sys.path[0] = '<script dir>'  → sibling import: OK
-PYTHONNOUSERSITE=1 python3 -s -B main.py     → sys.path[0] = '<script dir>'  → sibling import: OK
-python3 -I -B main.py   (the v8 FAIL form)   → sys.path[0] = stdlib zip     → ModuleNotFoundError
-```
-
-Therefore `python3 -s -B pinned/launch-runtime.py …` puts `pinned/` at `sys.path[0]`, so the pinned launcher's bare
-top-level `from lease_generation import initialize_runtime_generation` (`f4008307:launch-runtime.py:15`, no `sys.path`
-manipulation) resolves to the **pinned** `pinned/lease_generation.py` — not the worktree, not a miss. **B6(c) holds.**
-
-## B7 — Broker env-isolation (still holds)
-
-`launch_verified_broker` passes `env=environment` (the constructed allow-list, **not** `os.environ`; contains no
-`PYTHONPATH`/`PYTHONHOME`/`PYTHONPYCACHEPREFIX`) to `Popen` (`:570`), and the broker command includes `-I` (`:552`).
-The broker imports the helper by explicit `--generation-module` path via `importlib`, so it never needs `sys.path[0]`
-— `-I` is correct there and does not affect it. (The env's `PYTHONNOUSERSITE`/`PYTHONDONTWRITEBYTECODE` are hardening
-flags, not path/home passthrough, and `-I` ignores all `PYTHON*` env anyway.)
-
-## B8 — Bytecode pinned-or-suppressed (still holds)
-
-`PYTHONDONTWRITEBYTECODE=1` (`:729`) and `PYTHONNOUSERSITE=1` (`:730`) in the allow-list env; `-B` on **both** child
-commands (`:515` launcher, `:553` broker); `reject_pinned_bytecode` fails closed (`RuntimeError`) on any pre-existing
-`pinned/__pycache__` or `*.pyc` (`:498-501`) and is called **before each consumer** (`:535` launcher, `:562` broker).
-No unpinned `.pyc` can be executed.
-
-## B5 — 3-leg conjunction (still holds)
-
-`materialize_closure` reads launcher+helper+broker from **git-object bytes** (`git show <commit>:<path>`) and asserts
-`sha256 == pin` for each, fail-closed; `pinned/` is a fixture-private `0o700` dir inside the per-run fixture temp root;

-## 1. Current updater behavior + exact wipe mechanism (evidence)
-
-### 1.1 What runs on `mosaic update`
-
-`mosaic update` re-seeds the framework by invoking the **bash installer** in sync-only, keep mode:
-
-- `packages/mosaic/src/runtime/update-checker.ts:509` `buildReseedCommand()` returns
-  `bash <frameworkRoot>/install.sh` with env `MOSAIC_SYNC_ONLY=1`, `MOSAIC_INSTALL_MODE=keep`,
-  `MOSAIC_HOME=<mosaicHome>`.
-- The same `install.sh` is the direct/`tools/install.sh` upgrade path and the framework-vN migration path.
-
-So the destructive surface is **`packages/mosaic/framework/install.sh`**.
-
-### 1.2 The wipe
-
-`sync_framework()` (`install.sh:177`) performs, in `keep` mode:
-
-```
-rsync -a --delete --exclude .git --exclude .framework-version --exclude '*.pre-constitution.bak' \
-      [--exclude "/$path" for each PRESERVE_PATHS entry] SOURCE_DIR/ TARGET_DIR/
-```
-
-- `install.sh:199` — `rsync -a --delete`. **`--delete` prunes every path in `~/.config/mosaic`
-  that is NOT present in the shipped framework source**, unless excluded.
-- `install.sh:47` — `PRESERVE_PATHS` is the **only** thing standing between `--delete` and operator
-  data. It is a _denylist of exclusions_:
-  ```
-  PRESERVE_PATHS=("CONSTITUTION.md" "AGENTS.md" "SOUL.md" "USER.md" "TOOLS.md" "STANDARDS.md"
-    "memory" "sources" "credentials" "fleet/roster.yaml" "fleet/roster.json" "fleet/agents"
-    "fleet/run" "fleet/backlog" "fleet/roles.local")
-  ```
-- The cp-fallback (no rsync) is equally destructive: `install.sh:223`
-  `find "$TARGET_DIR" -mindepth 1 -maxdepth 1 ... -exec rm -rf {} +` then re-copies source, restoring
-  only PRESERVE_PATHS globs.
-
-**Root-cause model:** _"Everything under `~/.config/mosaic` is framework-owned and pruneable UNLESS
-explicitly preserved."_ Any operator path the list forgets is destroyed on the next upgrade.
-
-### 1.3 The exact operator paths wiped
-
-Cross-referencing the issue's operator-owned list against `PRESERVE_PATHS`:
-
-| Operator path (issue #791)                                        | In PRESERVE_PATHS?                      | Fate on `mosaic update` |
-| ----------------------------------------------------------------- | --------------------------------------- | ----------------------- |
-| `agents/*.conf` (per-agent runtime)                               | **NO**                                  | **WIPED**               |
-| `policy/*.md` (operator overlays)                                 | **NO**                                  | **WIPED**               |
-| `*.local.md` (SOUL/USER/STANDARDS)                                | **NO**                                  | **WIPED**               |
-| harvester / SOP artifacts + timers                                | **NO**                                  | **WIPED**               |
-| `tools/_lib/credentials.json`                                     | **NO** (`credentials/` dir ≠ this path) | **WIPED**               |
-| `fleet/agents/*.env`                                              | yes (`fleet/agents`, added by #631)     | survives                |
-| `memory/`, `fleet/roster.*`, `fleet/backlog`, `fleet/roles.local` | yes                                     | survives                |
-
-The `fleet/agents`, `memory`, `fleet/backlog` entries were **retro-added after prior incidents**
-(#631). This whack-a-mole is the structural signature of a denylist.
-
-**Stale-comment evidence:** `update-checker.ts:492` claims the reseed preserves
-"`SOUL/USER/*.local/credentials`" — but `PRESERVE_PATHS` contains **no `*.local` entry**. The code
-documents protection it does not deliver.
-
-### 1.4 Second code path (TS) — already non-destructive, but drifted
-
-`FileConfigAdapter.syncFramework()` (`packages/mosaic/src/config/file-adapter.ts:157`) →
-`syncDirectory()` (`packages/mosaic/src/platform/file-ops.ts:66`) is a **copy-overlay**: it copies
-source over target and skips preserved paths, but **never deletes** target paths absent from source
-(`file-ops.ts:77-109`). It is used by the wizard/init flow, not `mosaic update`.
-
-Two problems remain:
-
-1. Its `preservePaths` (`file-adapter.ts:164-185`) has **already diverged** from `install.sh` — it is
-   **missing `fleet/backlog` and `fleet/roles.local`**. Two hand-maintained denylists, drifted. This
-   is direct evidence for a single shared SSOT manifest.
-2. Even non-destructive, it will happily _overwrite_ an operator file that collides with a
-   framework-shipped path unless that path is on its (incomplete) preserve list.
-
-### 1.5 Existing snapshot is inadequate for rollback
-
-`make_snapshot()`/`restore_snapshot()` (`install.sh:76-87`) copy `TARGET_DIR` to `mktemp -d` under
-`/tmp`, restore **only on `ERR/INT/TERM` trap**, and are **deleted on success** (`cleanup_snapshot`,
-`install.sh:345`). Consequences: ephemeral `/tmp`, no retention, no post-success rollback, and **no
-`mosaic restore`**. It is crash-safety only, not the transactional safety net #791 requires.
-
----
-
-## 2. Fix (b) — Strict ownership separation [PRIMARY / root cause]
-
-### 2.1 Ownership model (invert to allow-list)
-
-Replace _"framework-owned unless preserved"_ with _"operator-owned unless framework-owned"_, resolved
-**per target path** with operator carve-outs winning inside shared framework subtrees.
-
-Two declared lists, one SSOT data file shipped in the framework
-(`framework/framework-manifest.json`), consumed by **both** bash and TS:
-
-- **`framework` globs** — paths the updater is entitled to create / overwrite / prune. Authored to
-  match exactly what the framework ships in `packages/mosaic/framework/` (e.g. `CONSTITUTION.md`,
-  `AGENTS.md`, `STANDARDS.md`, `TOOLS.md`, `guides/**`, `constitution/**`, `templates/**`, `tools/**`,
-  `skills/**`, `mcp/**`, `defaults/**`, `fleet/examples/**`, `fleet/roles/**`, `fleet/profiles/**`,
-  `fleet/roster.schema.json`).
-- **`operatorReserved` globs** — NEVER written or pruned, even nested inside a `framework` subtree;
-  these **win** over `framework` (deny-wins / most-specific-wins). At minimum:
-  `agents/**`, `policy/**`, `memory/**`, `sources/**`, `credentials/**`, `*.local.md`,
-  `tools/_lib/credentials.json`, `fleet/roster.yaml`, `fleet/roster.json`, `fleet/agents/**`,
-  `fleet/run/**`, `fleet/backlog/**`, `fleet/roles.local/**`, plus operator harvester/SOP artifacts.
-
-### 2.2 Ownership resolution for a target path `P`
-
-1. `P` matches `operatorReserved` → **operator-owned**: updater MUST NOT write, MUST NOT delete.
-2. else `P` matches `framework` → **framework-owned**: may overwrite; may prune **only if absent from
-   the current SOURCE** (a genuinely retired framework file).
-3. else (matches neither) → **UNKNOWN ⇒ operator-owned by default (fail-safe)**: never delete.
-
-Rule 3 is the actual root-cause fix: an operator path the manifest authors forget is still protected,
-because _unknown defaults to operator_. A denylist can never provide this guarantee.
-
-### 2.3 Sync mechanism change (the mechanically-critical part)
-
-`--delete` cannot express "prune only framework-owned" without re-enumerating every operator path
-(the denylist trap). So:
-
-1. **Drop `--delete` from the bulk sync.** Copy `SOURCE → TARGET` non-destructively (writes/overwrites
-   all framework files; deletes nothing). rsync without `--delete`, or the existing overlay copy.
-2. **Explicit manifest-scoped prune pass.** Iterate the **`framework` manifest** (not the whole tree);
-   for each framework path present in `TARGET` but **absent in `SOURCE`**, delete it — after
-   re-checking it does not match `operatorReserved`. Because the prune iterates only declared
-   framework globs, operator/unknown paths are **structurally unreachable** by deletion.
-
-This is implemented in both bash `sync_framework()` and TS `syncFramework()` from the shared manifest.
-A pure **prune-planner** function (TS) computes the delete-set from
-`(manifest, sourceListing, targetListing)` so the invariant is unit-testable in isolation.
-`PRESERVE_PATHS` becomes redundant (kept as a defense-in-depth alias mapping to `operatorReserved`, or
-removed) — either way the two lists stop drifting because they read one file.
-
-### 2.4 HARD GATE test — "upgrade touches no path outside the manifest"
-
-Filesystem-observation test in the existing `test-install-migration.sh` harness pattern (mktemp
-`MOSAIC_HOME`, `MOSAIC_SYNC_ONLY=1`), plus TS specs:
-
-1. Seed a throwaway `TARGET` with a realistic operator mix — one sentinel per operator class:
-   `agents/x.conf`, `policy/p.md`, `SOUL.local.md`, `memory/m.md`,
-   `tools/_lib/credentials.json` (with a secret value), `fleet/agents/a.env`, `fleet/roster.yaml`,
-   `harvester/sop.md`, **and a deliberately-unanticipated `unknown-operator-dir/x`**.
-2. Record hash+mtime of every sentinel.
-3. Run the upgrade from a `SOURCE` containing none of those operator paths.
-4. **Assert:** every sentinel exists, byte-identical, **mtime unchanged** (not even rewritten). The
-   `unknown-operator-dir` surviving proves the fail-safe default — a denylist could not pass this case.
-5. **Positive controls:** framework files WERE updated; a retired framework file WAS pruned.
-6. **Property test** (TS prune-planner): for fuzzed operator paths, `deleteSet ⊆ {matches framework ∧
-in target ∧ not in source}` and `deleteSet ∩ operatorReserved = ∅`.
-
----
-
-## 3. Fix (a) — Transactional pre-update snapshot [safety net]
-
-- **Destination:** `${XDG_STATE_HOME:-~/.local/state}/mosaic/backups/pre-update-<UTC-ts>/`.
-  **Outside `~/.config/mosaic`** (so no future sync can sweep it) and outside any repo.
-- **Perms:** dir `0700`, files `0600` — enforced with `umask 077` around the copy **and** explicit
-  `chmod`. Never world-readable.
-- **Scope:** the operator-owned surface (`operatorReserved` paths that exist) — bounded; does not copy
-  the framework tree.
-- **Timing:** taken before ANY mutation in the upgrade flow.
-- **Post-sync verify + selective restore:** after sync, diff the operator surface against the snapshot;
-  since (b) should never touch operator paths, any diff means a manifest bug — restore the affected
-  paths from the snapshot and warn loudly. This is precisely (a) catching a miss in (b).
-- **Retention:** keep N most-recent (default 5; `MOSAIC_BACKUP_RETENTION` override); prune older.
-- **`mosaic restore`:** `--list` (default, dry-run) enumerates snapshots by timestamp;
-  `--from <ts>` restores that snapshot over the operator surface, confirmation-gated. Reports
-  counts/paths only.
-- **Secret-safety:** snapshot copy and restore never emit file **contents**; only paths/counts.
-  Tests assert `0700/0600` and that no secret value appears in stdout/stderr.
-
----
-
-## 4. Fix (d) — Regeneration-from-SSOT [recovery]
-
-The incident's live blast radius: `fleet/agents/*.env` (systemd `EnvironmentFile` sources) gone →
-`mosaic-agent@<name>` boots **unit defaults** on restart (because `EnvironmentFile=-...` is
-absent-tolerant) → **silent identity/runtime/workdir downgrade**.
-
-The SSOT for those `.env` files is the roster. The reconciler **already** separates a
-`regenerate-projections-from-roster` projection phase from lifecycle
-(`packages/mosaic/src/fleet/fleet-reconciler.ts:93,234`; env rendering in
-`generated-env-boundary.ts:149-264`).
-
-**`mosaic fleet regen`** is therefore a **thin recovery-framed wrapper over the existing projection
-phase** — it does NOT reimplement fleet logic and does NOT preempt in-flight FCM cards (M4/M5):
-
-- Regenerates derivable config (per-agent `*.env.generated`, unit files) from roster SSOT.
-- **Preview-first:** dry-run default; `--write` to apply. Idempotent.
-- **Never restarts agents** (the recovery order forbids restart-before-verify).
-- Prints the runbook's next step (verify `EnvironmentFile` resolves, THEN restart).
-
-Alternatively documentable as `install.sh --relink` per the issue; `mosaic fleet regen` is preferred
-because it reuses the merged reconciler plumbing.
-
----
-
-## 5. Secret-safety approach (secrev surface)
-
-- Snapshots/backups: `0700`/`0600`, outside any repo, never world-readable. (§3)
-- No secret **value** ever emitted to logs/stdout/stderr by snapshot, restore, sync, or regen —
-  paths/counts only. Adversarial test: a secret value placed in `tools/_lib/credentials.json` must
-  never appear in installer or command output.
-- `tools/_lib/credentials.json` is an explicit `operatorReserved` carve-out inside the framework-owned
-  `tools/**` subtree — it is never overwritten or pruned.
-- The HARD GATE test doubles as a secret-safety test (asserts the credentials sentinel is untouched).
-
----
-
-## 6. Test plan (TDD, tests-first, ≥85% on new code, co-located `*.spec.ts`)
-
-1. **Manifest SSOT parity** — bash and TS resolve identical framework/operator sets from the one file;
-   a test fails if either path hard-codes a divergent list.
-2. **Manifest completeness** — every path shipped in `framework/` is covered by a `framework` glob (so
-   a new shipped file cannot silently fall outside the manifest and become un-prunable/undeclared).
-3. **HARD GATE** — upgrade touches nothing outside the manifest, incl. the unanticipated-path case
-   (§2.4).
-4. **Prune-planner** unit + property tests (§2.4.6).
-5. **Snapshot** — perms `0700/0600`, correct destination, retention prune, secret value absent from
-   output.
-6. **Restore** — `--list` / `--from` round-trip restores operator surface byte-exact; confirmation
-   gate; no secret leakage.
-7. **Regen** — roster→env projection deterministic + idempotent; dry-run makes no writes; `--write`
-   restores `*.env`; **never** issues a lifecycle/restart call.
-8. **Cross-path regression** — TS `syncFramework` and bash `install.sh` agree on a shared fixture
-   (closes the current #631-style drift).
-
-Gates before every push: `pnpm typecheck && pnpm lint && pnpm format:check` + mosaic package tests
-green. Never `--no-verify`.
-
----
-
-## 7. web1 recovery runbook (operator-agnostic; web1 specifics live in the issue as evidence only)
-
-For a currently-wiped fleet EnvironmentFile state — **do NOT service-restart while
-`fleet/agents/*.env` is absent** (a restart boots unit defaults and silently downgrades identity):
-
-1. **Regenerate:** `mosaic fleet regen --write` — rebuild `~/.config/mosaic/fleet/agents/*.env` from
-   roster SSOT.
-2. **Verify each unit resolves to the intended runtime/workdir** _before_ any restart:
-   `systemctl --user show mosaic-agent@<name> -p EnvironmentFile` and confirm the generated env exists
-   and carries the intended `MOSAIC_AGENT_*` runtime/workdir values.
-3. **Only then** `systemctl --user restart mosaic-agent@<name>`, one unit at a time.
-
-If config (not just fleet env) was lost, `mosaic restore --list` → `mosaic restore --from <ts>` before
-step 1.

+## What is the federated tier?
 
-## Held future procedure
+The federated tier is designed for multi-user and multi-host deployments. It consists of PostgreSQL 17 with pgvector extension (for embeddings and RAG), Valkey for distributed task queueing and caching, and a shared configuration across multiple Mosaic gateway instances. Use this tier when running Mosaic in production or when scaling beyond a single-host deployment.
 
-This section is non-operative and grants no current command authority until KBN-101-00, KBN-101-03, and KBN-101-05 land.
+## Prerequisites
 
-The deployment control plane—not an operator shell or deployment lifecycle hook—performs this
-exact held future sequence after activation authorization: external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `mosaic-db-migrator --verify` → Gateway/Compose readiness.
+- Docker and Docker Compose installed
+- Ports 5433 (PostgreSQL) and 6380 (Valkey) available on your host (or adjust environment variables)
+- At least 2 GB free disk space for data volumes
 
-1. External bootstrap provisions the approved database/extension prerequisites.
-2. TLS/roles are installed through the generation-pinned renderer.
-3. The dedicated one-shot runner executes `mosaic-db-migrator --run`.
-4. The same runner executes `mosaic-db-migrator --verify`, including readiness and the
-   importer-target attestation where that route is enabled.
-5. Only after successful verification may Gateway reach its independent verified-TLS Gateway
-   readiness gate.

-No step may be reordered, skipped, replaced by a raw SQL command, or delegated to an initialization
-hook.
-A missing extension, schema, migration, role, secret generation, or readiness proof is a failed
-control-plane precondition; it is not an instruction to start Compose, retry startup, or create
-anything directly.
+Run the federated overlay:
 
-## N-1 status and required disposition
+```bash
+docker compose -f docker-compose.federated.yml --profile federated up -d
+```
 
-The current branch retains historical federation artifacts, but they are not a deployable
-procedure. `docs/federation/TASKS.md` records their shipped status only. KBN-101-02 retires
-runtime/init DDL; KBN-101-05 owns the renderer/deployment handoff; KBN-101-06 verifies the
-finite scanner and command matrix; and KBN-101-07 owns this operator route. A path named in an
-inventory, a historical-status label, or a normative requirement cannot suppress the semantic
-checks above.
+This starts PostgreSQL 17 with pgvector and Valkey 8. The pgvector extension is created automatically on first boot.
 
-Until the activation certificate names an exact release, use no database startup or recovery
-command from this document. For the produced importer interface, see
-[the federated tier migration contract](../guides/migrate-tier.md); it is likewise non-operative
-until activation.
+Verify the services are running:
 
-## Federation and Step-CA reference
+```bash
+docker compose -f docker-compose.federated.yml ps
+```
 
-Federation uses PostgreSQL 17 with pgvector, Valkey, and a shared configuration across multiple
-Gateway instances. Step-CA issues federation peer X.509 certificates whose custom OIDs carry a
-grant and subject identity. The following facts are reference material only; provisioning and
-secret delivery remain deployment-control-plane work under the activation sequence.
+Expected output shows `postgres-federated` and `valkey-federated` both healthy.
 
-| OID                 | Name                     | Description           |
-| ------------------- | ------------------------ | --------------------- |
-| 1.3.6.1.4.1.99999.1 | `mosaic_grant_id`        | Federation grant UUID |
-| 1.3.6.1.4.1.99999.2 | `mosaic_subject_user_id` | Subject user UUID     |
+## Configure mosaic for federated tier
 
-The internal arc `1.3.6.1.4.1.99999` is development-only. Before an externally reachable
-production deployment, register an IANA Private Enterprise Number and version the assignments.
-Each value is DER-encoded as an ASN.1 UTF8String containing the UUID.
+Create or update your `mosaic.config.json`:
 
-The future activated Gateway requires `STEP_CA_URL`, `STEP_CA_PROVISIONER_PASSWORD`,
-`STEP_CA_PROVISIONER_KEY_JSON`, `STEP_CA_ROOT_CERT_PATH`, and `BETTER_AUTH_SECRET` through the
-reviewed secret mechanism. These names do not authorize shell exports, copied credential files,
-or an ad hoc service start.
+```json

+  "queue": "redis://localhost:6380"
+}

-## Failure disposition
+If you're using environment variables instead:
 
-- A TLS, CA, SAN, role, runner, or readiness failure is a control-plane incident. Preserve only
-  sanitized evidence and follow the approved rollback/repair record.
-- A pgvector/extension failure is a failed external-bootstrap or runner precondition. Do not use
-  direct extension SQL, init artifacts, or a startup retry as remediation.
-- A port, container, or Valkey problem does not permit bypassing the activation sequence.
-- Federation peer-key rotation remains deferred until its separately approved migration plan;
-  do not rotate `BETTER_AUTH_SECRET` without that plan.
+```bash
+export DATABASE_URL="postgresql://mosaic:mosaic@localhost:5433/mosaic"
+export REDIS_URL="redis://localhost:6380"
+```
+
+## Verify health
+
+Run the health check:
+
+```bash
+mosaic gateway doctor
+```
+
+Expected output (green):
+
+```
+Tier: federated  Config: mosaic.config.json
+  ✓ postgres         localhost:5433       (42ms)
+  ✓ valkey           localhost:6380       (8ms)
+  ✓ pgvector         (embedded)           (15ms)
+```
+
+For JSON output (useful in CI/automation):
+
+```bash
+mosaic gateway doctor --json
+```
+
+## Step 2: Step-CA Bootstrap
+
+Step-CA is a certificate authority that issues X.509 certificates for federation peers. In Mosaic federation, it signs peer certificates with custom OIDs that embed grant and user identities, enforcing authorization at the certificate level.
+
+### Prerequisites for Step-CA
+
+Before starting the CA, you must set up the dev password:
+
+```bash
+cp infra/step-ca/dev-password.example infra/step-ca/dev-password
+# Edit dev-password and set your CA password (minimum 16 characters)
+```
+
+The password is required for the CA to boot and derive the provisioner key used by the gateway.
+
+### Start the Step-CA service
+
+Add the step-ca service to your federated stack:
+
+```bash
+docker compose -f docker-compose.federated.yml --profile federated up -d step-ca
+```
+
+On first boot, the init script (`infra/step-ca/init.sh`) runs automatically. It:
+
+- Generates the CA root key and certificate in the Docker volume
+- Creates the `mosaic-fed` JWK provisioner
+- Applies the X.509 template from `infra/step-ca/templates/federation.tpl`
+
+The volume is persistent, so subsequent boots reuse the existing CA keys.
+
+Verify the CA is healthy:
+
+```bash
+curl https://localhost:9000/health --cacert /tmp/step-ca-root.crt
+```
+
+(If the root cert file doesn't exist yet, see the extraction steps below.)
+
+### Extract credentials for the gateway
+
+The gateway requires two credentials from the running CA:
+
+**1. Provisioner key (for `STEP_CA_PROVISIONER_KEY_JSON`)**
+
+```bash
+docker exec $(docker ps -qf name=step-ca) cat /home/step/secrets/mosaic-fed.json > /tmp/step-ca-provisioner.json
+```
+
+This JSON file contains the JWK public and private keys for the `mosaic-fed` provisioner. Store it securely and pass its contents to the gateway via the `STEP_CA_PROVISIONER_KEY_JSON` environment variable.
+
+**2. Root certificate (for `STEP_CA_ROOT_CERT_PATH`)**
+
+```bash
+docker cp $(docker ps -qf name=step-ca):/home/step/certs/root_ca.crt /tmp/step-ca-root.crt
+```
+
+This PEM file is the CA's root certificate, used to verify peer certificates issued by step-ca. Pass its path to the gateway via `STEP_CA_ROOT_CERT_PATH`.
+
+### Custom OID Registry
+
+Federation certificates include custom OIDs in the certificate extension. These encode authorization metadata:
+
+| OID                 | Name                   | Description           |
+| ------------------- | ---------------------- | --------------------- |
+| 1.3.6.1.4.1.99999.1 | mosaic_grant_id        | Federation grant UUID |
+| 1.3.6.1.4.1.99999.2 | mosaic_subject_user_id | Subject user UUID     |
+
+These OIDs are verified by the gateway after the CSR is signed, ensuring the certificate was issued with the correct grant and user context.
+
+### Environment Variables
+
+Configure the gateway with the following environment variables before startup:
+
+| Variable                       | Required | Description                                                                                               |
+| ------------------------------ | -------- | --------------------------------------------------------------------------------------------------------- |
+| `STEP_CA_URL`                  | Yes      | Base URL of the step-ca instance, e.g. `https://step-ca:9000` (use `https://localhost:9000` in local dev) |
+| `STEP_CA_PROVISIONER_KEY_JSON` | Yes      | JSON-encoded JWK from `/home/step/secrets/mosaic-fed.json`                                                |
+| `STEP_CA_ROOT_CERT_PATH`       | Yes      | Absolute path to the root CA certificate (e.g. `/tmp/step-ca-root.crt`)                                   |
+| `BETTER_AUTH_SECRET`           | Yes      | Secret used to seal peer private keys at rest; already required for M1                                    |
+
+Example environment setup:
+
+```bash
+export STEP_CA_URL="https://localhost:9000"
+export STEP_CA_PROVISIONER_KEY_JSON="$(cat /tmp/step-ca-provisioner.json)"
+export STEP_CA_ROOT_CERT_PATH="/tmp/step-ca-root.crt"
+export BETTER_AUTH_SECRET="<your-secret>"
+```
+
+## Troubleshooting
+
+### Port conflicts
+
+**Symptom:** `bind: address already in use`
+
+**Fix:** Stop the base dev stack first:
+
+```bash
+docker compose down
+docker compose -f docker-compose.federated.yml --profile federated up -d
+```
+
+Or change the host port with an environment variable:
+
+```bash
+PG_FEDERATED_HOST_PORT=5434 VALKEY_FEDERATED_HOST_PORT=6381 \
+  docker compose -f docker-compose.federated.yml --profile federated up -d
+```
+
+### pgvector extension error
+
+**Symptom:** `ERROR: could not open extension control file`
+
+**Fix:** pgvector is created at first boot. Check logs:
+
+```bash
+docker compose -f docker-compose.federated.yml logs postgres-federated | grep -i vector
+```
+
+If missing, exec into the container and create it manually:
+
+```bash
+docker exec <postgres-federated-id> psql -U mosaic -d mosaic -c "CREATE EXTENSION vector;"
+```
+
+### Valkey connection refused
+
+**Symptom:** `Error: connect ECONNREFUSED 127.0.0.1:6380`
+
+**Fix:** Check service health:
+
+```bash
+docker compose -f docker-compose.federated.yml logs valkey-federated
+```
+
+If Valkey is running, verify your firewall allows 6380. On macOS, Docker Desktop may require binding to `host.docker.internal` instead of `localhost`.
+
+## Key rotation (deferred)
+
+Federation peer private keys (`federation_peers.client_key_pem`) are sealed at rest using AES-256-GCM with a key derived from `BETTER_AUTH_SECRET` via SHA-256. If `BETTER_AUTH_SECRET` is rotated, all sealed `client_key_pem` values in the database become unreadable and must be re-sealed with the new key before rotation completes.
+
+The full key rotation procedure (decrypt all rows with old key, re-encrypt with new key, atomically swap the secret) is out of scope for M2. Operators must not rotate `BETTER_AUTH_SECRET` without a migration plan for all sealed federation peer keys.
+
+## OID Assignments — Mosaic Internal OID Arc
+
+Mosaic uses the private enterprise arc `1.3.6.1.4.1.99999` for custom X.509
+certificate extensions in federation grant certificates.
+
+**IMPORTANT:** This is a development/internal OID arc. Before deploying to a
+production environment accessible by external parties, register a proper IANA
+Private Enterprise Number (PEN) at <https://pen.iana.org/pen/PenApplication.page>
+and update these assignments accordingly.
+
+### Assigned OIDs
+
+| OID                   | Symbolic name                     | Description                                               |
+| --------------------- | --------------------------------- | --------------------------------------------------------- |
+| `1.3.6.1.4.1.99999.1` | `mosaic.federation.grantId`       | UUID of the `federation_grants` row authorising this cert |
+| `1.3.6.1.4.1.99999.2` | `mosaic.federation.subjectUserId` | UUID of the local user on whose behalf the cert is issued |
+
+### Encoding
+
+Each extension value is DER-encoded as an ASN.1 **UTF8String**:
+
+```
+Tag    0x0C        (UTF8String)
+Length 0x24        (36 decimal — fixed length of a UUID string)
+Value  <36 ASCII bytes of the UUID>
+```
+
+The step-ca X.509 template at `infra/step-ca/templates/federation.tpl`
+produces this encoding via the Go template expression:
+
+```
+{{ printf "\x0c\x24%s" .Token.mosaic_grant_id | b64enc }}
+```
+
+The resulting base64 value is passed as the `value` field of the extension
+object in the template JSON.
+
+### CA Environment Variables
+
+The `CaService` (`apps/gateway/src/federation/ca.service.ts`) requires the
+following environment variables at gateway startup:
+
+| Variable                       | Required | Description                                                          |
+| ------------------------------ | -------- | -------------------------------------------------------------------- |
+| `STEP_CA_URL`                  | Yes      | Base URL of the step-ca instance, e.g. `https://step-ca:9000`        |
+| `STEP_CA_PROVISIONER_PASSWORD` | Yes      | JWK provisioner password for the `mosaic-fed` provisioner            |
+| `STEP_CA_PROVISIONER_KEY_JSON` | Yes      | JSON-encoded JWK (public + private) for the `mosaic-fed` provisioner |
+| `STEP_CA_ROOT_CERT_PATH`       | Yes      | Absolute path to the step-ca root CA certificate PEM file            |
+
+Set these variables in your environment or secret manager before starting
+the gateway. In the federated Docker Compose stack they are expected to be
+injected via Docker secrets and environment variable overrides.
+
+### Fail-loud contract
+
+The CA service (and the X.509 template) are designed to fail loudly if the
+custom OIDs cannot be embedded:
+
+- The template produces a malformed extension value (zero-length UTF8String
+  body) when the JWT claims `mosaic_grant_id` or `mosaic_subject_user_id` are
+  absent. step-ca rejects the CSR rather than issuing a cert without the OIDs.
+- `CaService.issueCert()` throws a `CaServiceError` on every error path with
+  a human-readable `remediation` string. It never silently returns a cert that
+  may be missing the required extensions.

 # Fleet Launch Runbook
 
-The local fleet roster is the sole writable desired-state authority for membership and launch policy.
-Generated environment files are rebuildable projections, not an operator-editable command surface.
+How every Mosaic fleet agent — workers **and** the orchestrator — is launched, and how to
+configure each one. The guiding principle: **one roster-driven launcher**. There is no bespoke
+per-agent launch script; the roster plus per-agent `.env` files are the single source of launch
+config.
 
-## Launch chain
+## The launch chain
 
-| Layer               | Responsibility                                                                                                                  |
-| ------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
-| Roster              | `fleet/roster.yaml` supplies the agent name, class, supported runtime, model, reasoning, tool policy, workdir, and tmux socket. |
-| Projection writer   | Renders deterministic `fleet/agents/<name>.env.generated` from the roster.                                                      |
-| Optional local data | Reads a strict, data-only `fleet/agents/<name>.env.local`; it cannot shadow generated keys.                                     |
-| systemd             | Starts the launcher with `env -i` and fixed bootstrap data. It does not preload either environment file.                        |
-| session launcher    | Validates generated and local data before it queries, creates, or stops an exact tmux session.                                  |
-| runtime launch      | Derives the fixed `mosaic yolo <runtime>` argument array from validated roster data, then seeds the runtime contract.           |
+| Layer            | File                                              | Responsibility                                                                                                                                              |
+| ---------------- | ------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| systemd unit     | `mosaic-agent@<role>.service`                     | One templated unit per role; `ExecStart` runs the session launcher with the instance name `%i`. Defaults `MOSAIC_AGENT_RUNTIME=pi`, `MOSAIC_AGENT_NAME=%i`. |
+| session launcher | `tools/fleet/start-agent-session.sh <role>`       | Builds the launch command, opens the tmux pane, wires the heartbeat.                                                                                        |
+| launch command   | `mosaic yolo <runtime>` (or a per-agent override) | Replaces the pane's foreground process with the runtime, fully seeded.                                                                                      |
+| seeding          | `mosaic`'s `composeContract()`                    | Injects the Constitution/USER/TOOLS/runtime contract, `*.local` overlays, **and** the Fleet-Comms cheat-sheet — all via `--append-system-prompt`.           |
 
-The launcher never `source`s or `eval`s an environment file and never accepts an environment-supplied
-command. `MOSAIC_AGENT_COMMAND`, command/channel overrides, unknown keys, generated-key shadowing,
-secret-like key names, duplicate keys, comments, quoted/export syntax, and unsafe values are rejected.
+Per-agent overrides live in `fleet/agents/<role>.env`, generated from `roster.yaml` by
+`generateAgentEnv` (`packages/mosaic/src/commands/fleet.ts`) and consumed by the launcher.
 
-## Generated and local files
+## Worker launch path (default)
 
-`<name>.env.generated` is complete, deterministic, and written only by Mosaic. Its ordered keys are:
+1. `roster.yaml` carries each agent's `runtime` and optional `model_hint`.
+2. `generateAgentEnv` emits `fleet/agents/<role>.env` with `MOSAIC_AGENT_NAME`,
+   `MOSAIC_AGENT_RUNTIME`, and `MOSAIC_AGENT_MODEL`.
+3. `start-agent-session.sh` has no `MOSAIC_AGENT_COMMAND` set, so it falls through to the default
+   (line ~44):
+   ```sh
+   MOSAIC_AGENT_COMMAND="mosaic yolo $MOSAIC_AGENT_RUNTIME${MOSAIC_AGENT_MODEL:+ --model $MOSAIC_AGENT_MODEL}"
+   ```
+4. The launcher bakes `MOSAIC_AGENT_NAME` into the pane command (line ~118), so `composeContract`
+   can inject the Fleet-Comms cheat-sheet for that role.
 
-```dotenv
-MOSAIC_AGENT_NAME=<roster name>
-MOSAIC_AGENT_CLASS=<roster class>
-MOSAIC_AGENT_RUNTIME=<roster runtime>
-MOSAIC_AGENT_MODEL=<roster model hint>
-MOSAIC_AGENT_REASONING=<roster reasoning>
-MOSAIC_AGENT_TOOL_POLICY=<roster tool policy>
-MOSAIC_AGENT_WORKDIR=<absolute roster work directory>
-MOSAIC_TMUX_SOCKET=<roster socket or empty>
+That is the whole worker path: roster → `.env` → `mosaic yolo <runtime>` → seeded pane.
+
+## Orchestrator fold (PATH A — ships today)
+
+The orchestrator is **just another roster agent** launched through the canonical path — not a
+snowflake script.
+
+| Piece              | Value                               |
+| ------------------ | ----------------------------------- |
+| host-side launcher | `orchestrator-launch.sh`            |
+| systemd unit       | `mosaic-fleet-orchestrator.service` |
+| tmux session       | `orchestrator` (role-named)         |
+
+Set its launch command via `fleet/agents/orchestrator.env`:
+
+```sh
+MOSAIC_AGENT_COMMAND='mosaic yolo claude --channels plugin:discord@<channel>'
 ```
 
-The generated launch contract supports `claude`, `codex`, `opencode`, and `pi`. `mosaic fleet add`
-rejects another runtime before it writes the roster or modifies generated, local, or quarantine state.
-The legacy dogfood stub remains an observability-only canary on its separate `mosaic-factory` socket;
-it has no generated-launch adapter and cannot be added through this path.
+When `MOSAIC_AGENT_COMMAND` is set, `start-agent-session.sh`'s `if [ -z "$MOSAIC_AGENT_COMMAND" ]`
+guard (line ~41) is false, so the line-44 default — **including its hardcoded `yolo`** — is skipped
+entirely. The override fully controls the runtime and flags. Routing through `mosaic yolo claude`
+(rather than a raw `claude` invocation) is what gives the orchestrator the same full
+`composeContract` seeding + Fleet-Comms cheat-sheet as every worker, with `--channels` and any
+other flags passed straight through to the `claude` binary.
 
-`<name>.env.local` is optional and may contain only non-secret machine data:
+## Launch gotchas
 
-- `MOSAIC_RUNTIME_BIN`
-- `MOSAIC_HEARTBEAT_RUN_DIR`
-- `MOSAIC_HEARTBEAT_INTERVAL`
-- `MOSAIC_CLAUDE_JSON`
-- `CLAUDE_CONFIG_DIR`
+1. **Flag conflict.** `mosaic yolo claude` already injects `--dangerously-skip-permissions`. Do
+   **not** also pass `--permission-mode bypassPermissions` — the `claude` binary would receive both.
+   Use `mosaic yolo claude …` alone (yolo covers the unattended posture), **or** non-yolo
+   `mosaic claude --permission-mode bypassPermissions …`. Never mix the two.
+2. **`MOSAIC_AGENT_NAME` must reach the pane.** The launcher bakes it from the instance name, and
+   `composeContract` gates the Fleet-Comms block on it (`launch.ts`, in `composeContract`) — **and**
+   the role must be a member of `roster.yaml`, or the block resolves empty.
+3. **`launchRuntime` guards.** `mosaic yolo claude` runs `checkSoul` / `checkRuntime` /
+   `checkSequentialThinking`. The host needs `SOUL.md` and the sequential-thinking MCP, or the
+   launch aborts (a raw `claude` invocation skipped these checks). Dry-run the composed command in a
+   throwaway tmux session before swapping a live launcher.
 
-Paths must be safe absolute paths and the heartbeat interval must be a positive integer. Projection,
-local, and quarantine files must be private regular files; the managed directories must be real,
-private, non-symlink paths. Violations fail closed before tmux interaction.
+## Why per-agent `.env` survives upgrades (#632)
 
-## Legacy input and diagnostics
+`install.sh` `PRESERVE_PATHS` includes `fleet/*.yaml`, `fleet/agents`, and `fleet/run`, so
+`mosaic update`'s framework re-seed **preserves** your roster and per-agent `.env` overrides
+(glob-aware `cp` fallback; matching TS parity in `file-adapter.ts`). Before #632, an auto re-seed
+could wipe them — which is exactly why PATH A's `.env` override is safe to rely on now.
 
-A legacy `<name>.env` is input only during projection generation. Roster-owned keys are regenerated;
-valid allowed local data can move to `.env.local`; invalid legacy input is privately retained at
-`<name>.env.quarantine`. Neither legacy nor quarantine files are launch authority.
+## Inspecting the comms wiring
 
-Diagnostics expose only rule code, key name, and a SHA-256 content hash. They do not reveal command
-text, credentials, or other values.
+- `mosaic fleet comms-block <role>` prints the Fleet-Comms cheat-sheet a given role receives at
+  launch — its `[host:session]` identity, the exact `agent-send.sh` command for each peer, and the
+  FLIP / `--verify` conventions. `--host <h>` previews a cross-host view. An unknown role or missing
+  roster **fails loud** (stderr + non-zero exit), so a typo is never a silent no-op.
+- Versus `mosaic compose-contract <runtime>`: that emits the **whole** system prompt and reads the
+  role from `MOSAIC_AGENT_NAME` (a full-prompt smoke test). `comms-block` is the targeted,
+  explicit-arg, comms-only view — e.g. `mosaic fleet comms-block coder0-0` to preview a peer.
 
-## Launch and stop behavior
+## North Star / future direction
 
-The launcher obtains the agent's socket only from the validated generated projection. It creates or
-checks the exact `=<agent-name>` tmux target; it never uses an ambient socket or fuzzy session match.
-The same strict parser runs before exact-stop behavior. A fresh native Pi heartbeat remains authoritative;
-the shell sidecar only provides fallback state when the native marker is stale or absent.
+**Vision:** a webUI lets the user edit each agent's launch config — switch **harness**
+(claude / pi / codex / opencode), toggle **yolo**, pick a **model**, set a **command/channels**
+override — with no terminal.
 
-`mosaic agent comms-block <exact-member>` can inspect that exact roster member's resolved Fleet-Comms
-block. It is a read-only inspection tool and fails loudly for an unknown exact member or missing roster.
-On Linux, the installed roster, TOOLS contract, and executable helper are opened through a held
-descriptor chain rooted at `/`; every managed path component uses no-follow traversal, and content plus
-execute validation stay bound to the same opened file. Systems without Linux `/proc/self/fd` support
-fail closed rather than falling back to pathname revalidation.
+**Continuity — this is not a new launch path.** It is a data-model + UI-binding layer over the
+existing roster-driven launcher. Field-by-field status today:

-# Create, Inspect, Update, and Delete a Local Fleet Agent
-
-Use the local roster-v2 control plane only. These commands change desired state and derived environment projections; they never start, stop, reconcile, inspect, or otherwise act on systemd, tmux, sessions, or runtimes.
-
-## Read and plan first
-
-```sh
-mosaic fleet get <name>
-mosaic fleet plan create --expected-generation <n> --agent '<json>'
-mosaic fleet plan update <name> --expected-generation <n> --agent '<json>'
-mosaic fleet plan delete <name> --expected-generation <n>
-```
-
-`plan create` takes the name from `--agent`. `plan update` and `plan delete` require the target name immediately after the operation. A plan is deterministic and side-effect free: it validates the complete proposed roster and projection targets without changing files. Use `--dry-run` on `create`, `update`, or `delete` for the same no-write result.
-
-Every successful command prints JSON. `get` returns `{ "generation", "agent" }`; mutation results contain `plan`, `applied`, `authoritativeRoster`, and `projections`.
-
-## Create safely
-
-```sh
-mosaic fleet create --expected-generation 7 --agent '{
-  "name":"coder0",
-  "alias":"Coder 0",
-  "className":"code",
-  "runtime":"pi",
-  "provider":"openai",
-  "model":"gpt-5.6-sol",
-  "reasoning":"high",
-  "toolPolicy":"code",
-  "workingDirectory":"/srv/mosaic",
-  "persistentPersona":false,
-  "resetBetweenTasks":true,
-  "launch":{"yolo":true}
-}'
-```
-
-Create defaults to `enabled: true` and `desired_state: stopped`. It does not start a process. Add `--persisted-start` only to persist `desired_state: running`; that still does not start a runtime in this M2 command. The JSON payload is an allowlist of the roster-v2 fields shown above plus `launch.yolo`; command, channel, secret-reference, and other unknown keys are rejected rather than ignored. The JSON error exposes only a stable code, never the rejected value.
-
-## Update and delete safely
-
-```sh
-mosaic fleet update coder0 --expected-generation 8 --agent '<complete JSON agent payload>'
-mosaic fleet delete coder0 --expected-generation 9
-```
-
-Updates require a complete agent JSON payload and preserve the stable name. Delete removes only the exact roster-owned `coder0.env.generated` projection. It retains `coder0.env.local`, legacy `coder0.env`, `coder0.env.quarantine`, and every unrelated projection. A delete dry-run leaves all of those files byte-identical.
-
-## Handle generation conflicts
-
-Every mutation requires the current authoritative `--expected-generation`. A stale value returns JSON `error.code: "stale-generation"` with a non-zero exit. Reload with `mosaic fleet get <name>` or reread the roster, plan again using the returned generation, then retry. A concurrent mutation returns `concurrent-mutation`; do not force or bypass the lock.
-
-## Interpret partial failures
-
-The roster is authoritative and is written before derived projections. A late projection I/O failure returns non-zero with redacted, actionable JSON:
-
-```json
-{
-  "applied": false,
-  "authoritativeRoster": "committed",
-  "projections": "incomplete",
-  "recovery": {
-    "code": "projection-apply-failed",
-    "action": "regenerate-projections-from-roster"
-  }
-}
-```
-
-This is not a rollback and not a no-op: reload the roster because its generation and membership were committed, regenerate projections from that roster, then plan a new mutation. Recovery output never contains environment values, credentials, or command text.
-
-## Exit and boundary behavior
-
-Handled validation errors and partial projection failures exit non-zero. `plan`/`--dry-run` and normal mutation JSON make the state explicit; scripts should use both the exit code and `authoritativeRoster`/`projections`, not `applied` alone.
-
-The commands operate only on `<mosaic-home>/fleet/roster.yaml`, the local roster desired-state authority. They do not accept arbitrary commands, channels, secrets, remote/connector actions, migration/canary actions, or runtime lifecycle operations.

-Start with `--dry-run`.

-
-`start`, `stop`, and `restart` are explicit one-shot exact-service actions. They do not persist a lifecycle change. Roster CRUD is the only way to change persisted desired state.

-Every command prints JSON. Observation commands report drift without mutation; `verify` exits non-zero on ownership mismatch, unmanaged sessions, or drift. A failed apply that wrote some derived projections reports `projections: "incomplete"` with bounded recovery to regenerate from the roster.

-- **Canonical profile:** the artifact is loaded through `loadProfiles`, which uses the shared
-  baseline-plus-`roles.local` persona resolver and rejects unreadable or unresolved classes.
-- **Canonical service policy:** the artifact is loaded through the operator-interaction service
-  policy reader and provisioned with a generic supplied identity. It validates its runtime, model,
-  reasoning, and legacy tool-policy compatibility without hardcoding a product identity.

-FCM-M4-001 layers an executable migration posture over the same 13-entry M1 inventory without
-changing the retained artifact classification:
-
-- every `v1-fixture` is previewed only with explicit class and lifecycle evidence;
-- every `canonical-profile` remains validated by the shared baseline-plus-`roles.local` resolver;
-- the canonical service policy remains generic and uses only the approved tool-policy alias.
-
-`validateShippedFleetMigrationDispositions` first runs the existing executable M1 guard, then requires
-explicit decisions and lifecycle observations and executes `previewV1ToV2Migration` for every shipped
-v1 fixture. `collectShippedFleetMigrationDispositions` derives the 13-entry posture directly from
-`SHIPPED_FLEET_ARTIFACT_DISPOSITIONS`, so additions or removals continue to fail the M1 guard rather
-than creating a second artifact list. None of these dispositions claims a cutover, canary, or

-pnpm --filter @mosaicstack/mosaic test -- v1-v2-migration.spec.ts \
-  -t "validates all 13 shipped artifacts and executes ready previews for every v1 fixture"

-The guard is intentionally limited to shipped assets and validation. It does not generate
-environment files, mutate a roster, reconcile a fleet, migrate an installed roster, or launch an

-preserved; if both supported root aliases are absent, the production v1 default is the literal empty socket.
-A matching `socketName` decision is accepted and an incompatible decision blocks, but a decision never
-supplies or repairs a missing source socket. If v1 omitted `tool_policy`, decisions must supply an
-explicit replacement; it is never derived from `class`. `model_hint` is never split or treated as

-inventory remains position-addressed evidence of the exact input. Recovery is marked non-executable and
-assigns the executable gate to FCM-M4-002.
-
-Before any later cutover, preserve these artifacts:
-
-1. authoritative v1 roster backup;
-2. agent environment backup, including `.env.local` and private quarantine inputs;
-3. reviewed lifecycle observations;
-4. canonical candidate v2 roster and its SHA-256.
-
-See [backup and restore](../operations/backup-restore.md). Preview output is migration-readiness
-evidence, not proof that migration, canary, or rollback occurred.

-# Fleet Configuration Backup and Restore Boundary
-
-**Issue:** #758 · **Card:** FCM-M4-001
-
-This page defines evidence that must exist before a roster v1-to-v2 cutover. FCM-M4-001 lists these
-prerequisites in non-executable recovery evidence but does not validate that backups exist and performs
-no backup, migration, canary, or restore. FCM-M4-002 owns the executable reversible canary and rollback
-gates.
-
-## Preserve before cutover
-
-- The authoritative v1 roster, byte-for-byte, with a SHA-256 identity.
-- Existing per-agent legacy `.env`, strict `.env.local`, and quarantine files under private
-  permissions.
-- Reviewed per-local-agent systemd and exact-socket tmux observations.
-- The canonical v2 candidate and its SHA-256 identity.
-- Inventory-only remote agents and connector configuration as evidence, not local control-plane input.
-
-`.env.generated` is a rebuildable projection and is not restored as authority. It must be regenerated
-from the selected authoritative roster. `.env.local` is operator-owned strict data and must not be
-overwritten or absorbed into generated output. Quarantined source remains private evidence; public
-diagnostics expose only rule code, key name, and SHA-256.
-
-## Restore requirements
-
-A later rollback implementation must restore the authoritative roster and operator-owned environment
-files, regenerate managed projections, and preserve each reviewed pre-cutover stopped/running state.
-It must never start an agent observed stopped and must never reconcile an inventory-only remote or
-connector entry.
-
-The preview evidence deliberately records:
-
-- `executable: false`;
-- required backup artifacts;
-- source and candidate identities;
-- lifecycle observations and resulting desired states;
-- environment relocation/quarantine dispositions;
-- FCM-M4-002 as the executable rollback gate owner.

-Do not interpret a ready preview as a completed backup, migration, canary, or rollback.

-# Reconcile and Recover a Local Fleet
-
-## Safe sequence
-
-1. Read `mosaic fleet doctor` and `mosaic fleet status`.
-2. Run `mosaic fleet apply --expected-generation <n> --dry-run`.
-3. Resolve stale generation, ownership mismatch, unsafe path, projection validation, or unmanaged-session findings before applying.
-4. Run `mosaic fleet apply --expected-generation <n>` only after the plan is understood.
-
-The reconciler uses the exact roster tmux socket, exact holder session, private installation holder identity, and the complete expected global environment. For mutations it acquires its exclusive lock before rereading the canonical roster and fencing its generation; only that under-lock roster drives validation, planning, projections, and lifecycle effects. Before effects, its exclusive lock proves real private `MOSAIC_HOME` and `fleet` ancestors, uses a private `0600` lock leaf, and binds cleanup to the created file identity and ownership token. A fake holder, contaminated global environment, missing identity, unsafe lock path, or unmanaged session fails closed. It does not adopt, kill, or rename any unproven session. A crash can leave a stale lock for explicit operator inspection; reconciliation deliberately does not guess ownership or remove it.
-
-## Partial results
-
-The roster is never changed by reconciliation. If derived projection application partially fails, JSON reports:
-
-```json
-{
-  "applied": false,
-  "authoritativeRoster": "unchanged",
-  "projections": "incomplete",
-  "lifecycle": "not-applied",
-  "recovery": { "code": "projection-apply-failed", "action": "regenerate-projections-from-roster" }
-}
-```
-
-If projections completed but lifecycle work failed, JSON reports `projections: "complete"`, `lifecycle: "incomplete"`, and the bounded action `rerun-after-inspecting-owned-resources`. If lock cleanup cannot be proven after an effect result, it adds `cleanup: { "code": "lock-cleanup-failed", "action": "inspect-lock-before-retry" }` without changing the known projection, lifecycle, or primary recovery truth. Inspect the retained lock before retrying; no rollback, release, or stale-lock removal is implied. Results do not include environment values, secrets, or privileged command content.

-# Local Fleet Agent Mutations
-
-FCM-M2-002 provides local roster-v2 create, get, update, delete, and plan operations. They only change desired state and derived environment projections. They never start, stop, inspect, reconcile, or otherwise act on runtimes, systemd units, tmux sessions, or heartbeats.
-
-## CLI contract
-
-The commands operate only on the canonical `<mosaic-home>/fleet/roster.yaml` v2 authority and print one JSON object to stdout. `--agent` is a JSON object with the roster agent fields expressed as `className`, `toolPolicy`, `workingDirectory`, `persistentPersona`, `resetBetweenTasks`, and `launch: { "yolo": boolean }`.
-
-```sh
-mosaic fleet get <name>
-mosaic fleet plan <create|update|delete> [name] --expected-generation <n> [--agent '<json>'] [--persisted-start]
-mosaic fleet create --expected-generation <n> --agent '<json>' [--dry-run] [--persisted-start]
-mosaic fleet update <name> --expected-generation <n> --agent '<json>' [--dry-run]
-mosaic fleet delete <name> --expected-generation <n> [--dry-run]
-```
-
-`get` returns the authoritative generation and the selected agent. `plan create` derives its name from `--agent`; `plan update <name>` and `plan delete <name>` require the target name. `--agent` accepts only the documented roster-v2 request fields and `launch.yolo`; unknown keys such as commands, channels, or secret references are rejected. Rejection diagnostics return only the stable `invalid-request` code and never echo a rejected value. `plan` and `--dry-run` validate the complete proposed roster and projections but write neither the roster nor projections. `--persisted-start` is available only for a create request: it records `desired_state: running`, but does not start a process. Without it, create records `enabled: true` and `desired_state: stopped`. Handled failures return JSON with `error.code` and exit non-zero; unclassified validation/projection failures use the redacted `mutation-failed` code.
-
-## Generation, validation, and idempotency
-
-Each create, update, or delete request includes `expectedGeneration`. A request whose expected value differs from the authoritative roster generation fails with `stale-generation`; reload and retry with a newly computed plan. A private mutation lock rejects concurrent writers with `concurrent-mutation`.
-
-`planFleetAgentMutation` is deterministic and side-effect free. `executeFleetAgentMutation` validates the complete proposed roster through the existing structural and shared persona resolver, prepares generated/local/quarantine projections, and writes the roster authority atomically before applying derived projections. Equivalent create retries and delete requests for an already-absent agent are idempotent no-ops.
-
-Delete removes only the exact `<name>.env.generated` projection for the removed roster entry. Operator-owned `<name>.env.local`, legacy `<name>.env`, quarantine records, and unrelated projections remain untouched. An already-absent generated projection is treated as stale derived state, not as a failed mutation.
-
-## Result and recovery
-
-Mutation results are JSON-safe objects with `applied`, `authoritativeRoster`, `projections`, `plan`, and—only if a derived projection write fails after the authoritative roster write—a recovery object. `applied` is true only when every roster and derived-projection write completed. The explicit state fields prevent a partial result from being mistaken for a rollback or a no-op:
-
-```json
-{
-  "applied": false,
-  "authoritativeRoster": "committed",
-  "projections": "incomplete",
-  "recovery": {
-    "code": "projection-apply-failed",
-    "action": "regenerate-projections-from-roster"
-  }
-}
-```
-
-Dry-runs and idempotent no-ops report `authoritativeRoster: "unchanged"` and `projections: "not-applied"`; a complete mutation reports `"committed"` and `"complete"`. Recovery output identifies the authoritative roster path and regeneration action only. It never contains generated/local/quarantine values, credentials, or command text. A recovery result exits non-zero because the authoritative roster was persisted but derived projections require regeneration. Regenerate projections from the roster before attempting another mutation.

-mosaic fleet migrate-v1 preview --source <path> --decisions <path> --observations <path>
-```
-
-`migrate-v1 preview` is non-mutating: it emits value-free v1 inventory, a canonical semantically
-validated v2 candidate when ready, sanitized environment dispositions, and non-executable recovery
-evidence. It has no write, apply, canary, or rollback option. Missing preview inputs also return one stable
-blocked JSON object and a non-zero exit, rather than Commander text. See
-[the migration preview contract](../migration/v1-to-v2.md).
-
-`apply` and `reconcile` use roster desired state. `start`, `stop`, and `restart` are exact local one-shot lifecycle effects and never persist a desired-state edit. `status`, `verify`, and `doctor` are observational.
-
-Commands emit one JSON object. Handled precondition errors emit `{ "error": { "code": "..." } }` and exit non-zero. Partial derived/lifecycle effects use explicit `authoritativeRoster`, `projections`, `lifecycle`, and bounded `recovery` fields; they never claim rollback. Any additive `cleanup` diagnostic also exits non-zero, even where known effects are complete: it is not a clean completion and the lock requires inspection before retry.
-
-This control plane is separate from the gateway-backed `mosaic agent` catalog. It is local-only and rejects remote/connector lifecycle mutation, arbitrary command/channel/secret input, and unproven tmux ownership.

-
-The systemd templates do not load either environment file. They invoke Bash with a fixed, cleared
-bootstrap environment; the launcher reads and validates `.env.generated` and `.env.local` itself before
-it queries, creates, or stops an exact tmux session. It does not `source`, `eval`, or execute an
-environment-supplied command. Exact stop derives its socket from the same validated generated projection,
-not from systemd or ambient environment data.
-
-All projection, local, and quarantine files must be regular files with no group or world permissions.
-The agent environment directory must also be a real, non-symlink private directory; it is validated
-before either environment file is read or tmux is queried. Unsafe paths, symlinks, or permissions fail
-closed. Diagnostics identify only a rule code, key name, and SHA-256 content hash; they never print
-values, credential material, or command text.
-
-## Allowed data
-
-`.env.generated` is complete and ordered exactly as follows:
-
-```dotenv
-MOSAIC_AGENT_NAME=<roster name>
-MOSAIC_AGENT_CLASS=<roster class>
-MOSAIC_AGENT_RUNTIME=<roster runtime>
-MOSAIC_AGENT_MODEL=<roster model hint>
-MOSAIC_AGENT_REASONING=<roster reasoning>
-MOSAIC_AGENT_TOOL_POLICY=<roster tool policy>
-MOSAIC_AGENT_WORKDIR=<absolute roster work directory>
-MOSAIC_TMUX_SOCKET=<roster socket or empty>
-```
-
-The generated launch contract supports only `claude`, `codex`, `opencode`, and `pi`. `fleet add`
-uses that same runtime authority and rejects any other runtime before it writes the roster or changes
-projection, local, or quarantine files. The legacy dogfood stub on its separate `mosaic-factory`
-socket remains an observability canary; it has no generated-launch adapter and cannot be added through
-this projection path.
-
-`.env.local` may contain only these non-secret data keys:
-
-- `MOSAIC_RUNTIME_BIN`
-- `MOSAIC_HEARTBEAT_RUN_DIR`
-- `MOSAIC_HEARTBEAT_INTERVAL`
-- `MOSAIC_CLAUDE_JSON`
-- `CLAUDE_CONFIG_DIR`
-
-Local paths must be safe absolute paths and the interval must be a positive integer. Comments,
-quoted/export syntax, duplicate keys, unknown keys, generated-key shadowing, sensitive key names,
-and `MOSAIC_AGENT_COMMAND` are rejected. The launcher derives the only executable command from the
-validated runtime, model, and reasoning data; no arbitrary command compatibility path exists. When a
-Pi runtime writes a fresh `<name>.hb.native` marker, its native heartbeat remains authoritative; the
-shell sidecar resumes its `status=ok` fallback only after that marker is stale or absent.
-
-## Legacy disposition
-
-During projection generation, legacy roster-derived keys are regenerated from the roster. A valid
-allowed local value is relocated to `.env.local`; forbidden, malformed, duplicate, sensitive, and
-unknown legacy entries cause the legacy file to be moved to `.env.quarantine` and are represented by
-sanitized diagnostics. This is deterministic and idempotent after the legacy file has been consumed.
-
-## USC interface packet

-This card does not add a USC site file, write a USC roster, or run a site canary. The following is the
-consolidated downstream interface packet. Status is deliberately separated from checkout presence: no
-product release version has been evidenced for this interface set.

-The canonical source remains `<MOSAIC_HOME>/fleet/roster.yaml` for the current local fleet path.
-Generated environment data is a rebuildable projection, not an operator-editable source of membership,
-runtime policy, or lifecycle state.

-**Corrected downstream gates:** M2 supplies only parse/validation/projection evidence and does not
-permit a USC site canary, reconciliation, or lifecycle mutation. M3 must first define and validate the
-canonical local reconcile/lifecycle path. M4 then supplies preview/migration and its separate

-This card authorizes none of those actions.

-A stopped roster agent is never started by `apply` or `reconcile`. Direct lifecycle commands are explicit one-shot actions and do not change persisted desired state. Use roster CRUD with the explicit persisted-start option to change that desired state.
-
-All mutations require `--expected-generation <n>` and acquire one private roster-adjacent reconciliation lock before projection or lifecycle effects. Missing or stale generations and concurrent writers fail before effects; the lock is released after success, partial failure, or thrown lifecycle failure. Stale, ownership, unmanaged-session, unsupported-runtime, path, projection, and lifecycle-precondition failures return stable redacted JSON errors and a non-zero exit. No command targets a fuzzy tmux name, arbitrary socket, arbitrary command, channel, secret, or generated file as authority.

-# Local Fleet Status and Drift
-
-`mosaic fleet status [name]`, `verify`, and `doctor` are observational roster-v2 commands. They emit one JSON result and do not write projections, change desired state, start services, stop services, restart services, or mutate tmux.
-
-The report distinguishes:
-
-- `missing-session`: an enabled agent desired `running` has no exact roster-named tmux session.
-- `unexpected-session`: a desired-`stopped` agent still has its exact session.
-- `disabled-running`: a disabled roster agent has its exact session.
-- `unmanagedSessions`: sessions on the configured named socket that are neither the exact holder nor an exact roster agent.
-- `holder`: `owned`, `missing`, or `ownership-mismatch` after exact holder, private install identity, and complete global tmux environment validation.
-
-`doctor` and `status` classify rather than adopt, destroy, or repair unmanaged state. `verify` is observational too, but exits non-zero if ownership cannot be proven, unmanaged sessions exist, or drift is present. Reconciliation fails closed under those conditions and never kills or adopts an unmanaged session.

 # Deployment Guide
 
-> **Status: non-operative for PostgreSQL, federated, and bare-metal production.** The checked-in
-> Compose PostgreSQL service mounts legacy initialization SQL and the KBN-101 bootstrap, runner,
-> secret-renderer, and process-exec interfaces do not exist yet. This page does not authorize a
-> production deployment, database initialization, manual DDL, secret provisioning, or service
-> activation.
+This guide covers deploying Mosaic in two modes: **Docker Compose** (recommended for quick setup) and **bare-metal** (production, full control).
 
-## Current safe local route
+---
 
-Use PGlite only for current in-process data-layer work; it requires no PostgreSQL. A Gateway/Web
-local process is held because its unguarded dotenv loader can inherit a daemon PostgreSQL DSN and
-reach runtime DDL. If a local queue service is useful, start only Valkey:
+## Prerequisites

+
+---
+
+## Docker Compose Deployment (Quick Start)
+
+The `docker-compose.yml` at the repository root starts PostgreSQL 17 (with pgvector), Valkey 8, an OpenTelemetry Collector, and Jaeger.
+
+### 1. Clone and configure
 
 ```bash
-docker compose up -d valkey
+git clone <repo-url> mosaic
+cd mosaic
+cp .env.example .env
 ```
 
-This command intentionally does not start PostgreSQL. Do not run a broad Compose start, use its
-PostgreSQL initialization mount, infer that current Compose is a production/federated route, or
-start Gateway/Web until KBN-101-02 supplies fail-closed local-tier/DSN isolation.
+Edit `.env`. The minimum required change is:
 
-## Held future procedure
+```dotenv
+BETTER_AUTH_SECRET=<output of: openssl rand -base64 32>
+```
 
-PostgreSQL local, federated, Compose, and bare-metal production activation are held until these
-artifacts land and pass their independent gates:
+### 2. Start infrastructure services
 
-1. **KBN-101-00** external privileged bootstrap artifact;
-2. **KBN-101-03** sole `mosaic-db-migrator` runner and verified-readiness artifact; and

-it must not place credentials in a production environment file, a monorepo auto-load path, a shell
-export, command arguments, logs, or a manual secret-activation lifecycle instruction. Rotation and
-process replacement semantics must be delivered by the reviewed renderer/interface with generation,

+### 4. Initialize the database
 
-## Readiness and troubleshooting status
+```bash
+pnpm --filter @mosaicstack/db db:migrate
+```
 
-Until the future procedure is implemented, do not diagnose PostgreSQL with ad hoc SQL, connection
-strings, or initialization scripts. The future sanitized runner-verification readiness artifact is
-the required PostgreSQL readiness authority after its bootstrap/TLS prerequisites pass.
-For local PGlite development, diagnose application behavior without introducing a PostgreSQL
-connection.
+### 5. Build all packages
 
-Non-database local services may be inspected with their ordinary local health/log tools. Those
-checks do not certify PostgreSQL, federated deployment, or production readiness.
+```bash
+pnpm build
+```
+
+### 6. Start the gateway
+
+```bash
+pnpm --filter @mosaicstack/gateway dev
+```
+
+Or for production (after build):
+
+```bash
+node apps/gateway/dist/main.js
+```
+
+### 7. Start the web app
+
+```bash
+# Development
+pnpm --filter @mosaicstack/web dev
+
+# Production (after build)
+pnpm --filter @mosaicstack/web start
+```
+
+The web app runs on port `3000` by default.
+
+---
+
+## Bare-Metal Deployment
+
+Use this path when you want to manage PostgreSQL and Valkey yourself (e.g., existing infrastructure, managed cloud databases).
+
+### Step 1 — Install system dependencies
+
+```bash
+# Node.js 22 via nvm
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
+nvm install 22
+nvm use 22
+
+# pnpm
+npm install -g pnpm
+
+# PostgreSQL 17 with pgvector (Debian/Ubuntu example)
+sudo apt-get install -y postgresql-17 postgresql-17-pgvector
+
+# Valkey
+# Follow https://valkey.io/download/ for your distribution
+```
+
+### Step 2 — Create the database
+
+```sql
+-- Run as the postgres superuser
+CREATE USER mosaic WITH PASSWORD 'change-me';
+CREATE DATABASE mosaic OWNER mosaic;
+\c mosaic
+CREATE EXTENSION IF NOT EXISTS vector;
+```
+
+### Step 3 — Clone and configure
+
+```bash
+git clone <repo-url> /opt/mosaic
+cd /opt/mosaic
+cp .env.example .env
+```
+
+Edit `/opt/mosaic/.env`. Required fields:
+
+```dotenv
+DATABASE_URL=postgresql://mosaic:<password>@localhost:5432/mosaic
+VALKEY_URL=redis://localhost:6379
+BETTER_AUTH_SECRET=<openssl rand -base64 32>
+BETTER_AUTH_URL=https://your-domain.example.com
+GATEWAY_CORS_ORIGIN=https://your-domain.example.com
+NEXT_PUBLIC_GATEWAY_URL=https://your-domain.example.com
+```
+
+### Step 4 — Install dependencies and build
+
+```bash
+pnpm install
+pnpm build
+```
+
+### Step 5 — Run database migrations
+
+```bash
+pnpm --filter @mosaicstack/db db:migrate
+```
+
+### Step 6 — Start the gateway
+
+```bash
+node apps/gateway/dist/main.js
+```
+
+The gateway reads `.env` from the monorepo root automatically (via `dotenv` in `main.ts`).
+
+### Step 7 — Start the web app
+
+```bash
+# Next.js standalone output
+node apps/web/.next/standalone/server.js
+```
+
+The standalone build is self-contained; it does not require `node_modules` to be present at runtime.
+
+### Step 8 — Configure a reverse proxy
+
+#### Nginx example
+
+```nginx
+# /etc/nginx/sites-available/mosaic
+
+# Gateway API
+server {
+    listen 443 ssl;
+    server_name your-domain.example.com;
+
+    ssl_certificate     /etc/ssl/certs/your-domain.crt;
+    ssl_certificate_key /etc/ssl/private/your-domain.key;
+
+    # WebSocket support (for chat.gateway.ts / Socket.IO)
+    location /socket.io/ {
+        proxy_pass http://127.0.0.1:14242;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+
+    # REST + auth
+    location / {
+        proxy_pass http://127.0.0.1:14242;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+
+# Web app (optional — serve on a subdomain or a separate server block)
+server {
+    listen 443 ssl;
+    server_name app.your-domain.example.com;
+
+    ssl_certificate     /etc/ssl/certs/your-domain.crt;
+    ssl_certificate_key /etc/ssl/private/your-domain.key;
+
+    location / {
+        proxy_pass http://127.0.0.1:3000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
+
+#### Caddy example
+
+```caddyfile
+# /etc/caddy/Caddyfile
+
+your-domain.example.com {
+    reverse_proxy /socket.io/* localhost:14242 {
+        header_up Upgrade {http.upgrade}
+        header_up Connection {http.connection}
+    }
+    reverse_proxy localhost:14242
+}
+
+app.your-domain.example.com {
+    reverse_proxy localhost:3000
+}
+```
+
+---
+
+## Production Considerations
+
+### systemd Services
+
+Create a service unit for each process.
+
+**Gateway** — `/etc/systemd/system/mosaic-gateway.service`:
+
+```ini
+[Unit]
+Description=Mosaic Gateway
+After=network.target postgresql.service
+
+[Service]
+Type=simple
+User=mosaic
+WorkingDirectory=/opt/mosaic
+EnvironmentFile=/opt/mosaic/.env
+ExecStart=/usr/bin/node apps/gateway/dist/main.js
+Restart=on-failure
+RestartSec=5
+StandardOutput=journal
+StandardError=journal
+
+[Install]
+WantedBy=multi-user.target
+```
+
+**Web app** — `/etc/systemd/system/mosaic-web.service`:
+
+```ini
+[Unit]
+Description=Mosaic Web App
+After=network.target mosaic-gateway.service
+
+[Service]
+Type=simple
+User=mosaic
+WorkingDirectory=/opt/mosaic/apps/web
+EnvironmentFile=/opt/mosaic/.env
+ExecStart=/usr/bin/node .next/standalone/server.js
+Environment=PORT=3000
+Environment=HOSTNAME=127.0.0.1
+Restart=on-failure
+RestartSec=5
+StandardOutput=journal
+StandardError=journal
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable and start:
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable --now mosaic-gateway mosaic-web
+```
+
+### Log Management
+
+Gateway and web app logs go to systemd journal by default. View with:
+
+```bash
+journalctl -u mosaic-gateway -f
+journalctl -u mosaic-web -f
+```
+
+Rotate logs by configuring `journald` in `/etc/systemd/journald.conf`:
+
+```ini
+SystemMaxUse=500M
+MaxRetentionSec=30day
+```
+
+### Security Checklist
+
+- Set `BETTER_AUTH_SECRET` to a cryptographically random value (`openssl rand -base64 32`).
+- Restrict `GATEWAY_CORS_ORIGIN` to your exact frontend origin — do not use `*`.
+- Run services as a dedicated non-root system user (e.g., `mosaic`).
+- Firewall: only expose ports 80/443 externally; keep 14242 and 3000 bound to `127.0.0.1`.
+- Set `AGENT_FILE_SANDBOX_DIR` to a directory outside the application root to prevent agent tools from accessing source code.
+- If using `AGENT_USER_TOOLS`, enumerate only the tools non-admin users need.
+
+---
+
+## Troubleshooting
+
+### Gateway fails to start — "BETTER_AUTH_SECRET is required"
+
+`BETTER_AUTH_SECRET` is missing or empty. Set it in `.env` and restart.
+
+### `DATABASE_URL` connection refused
+
+Verify PostgreSQL is running and the port matches. The Docker Compose default is `5433`; bare-metal typically uses `5432`.
+
+```bash
+psql "$DATABASE_URL" -c '\conninfo'
+```
+
+### pgvector extension missing
+
+```sql
+\c mosaic
+CREATE EXTENSION IF NOT EXISTS vector;
+```
+
+### Valkey / Redis connection refused
+
+Check the URL in `VALKEY_URL`. The Docker Compose default is port `6380`.
+
+```bash
+redis-cli -u "$VALKEY_URL" ping
+```
+
+### WebSocket connections fail in production
+
+Ensure your reverse proxy forwards the `Upgrade` and `Connection` headers. See the Nginx/Caddy examples above.
+
+### Ollama models not appearing
+
+Set `OLLAMA_BASE_URL` to the URL where Ollama is running (e.g., `http://localhost:11434`) and set `OLLAMA_MODELS` to a comma-separated list of model IDs you have pulled.
+
+```bash
+ollama pull llama3.2
+```
+
+### OTEL traces not appearing in Jaeger
+
+Verify the collector is reachable at `OTEL_EXPORTER_OTLP_ENDPOINT`. With Docker Compose the default is `http://localhost:4318`. Check `docker compose ps` and `docker compose logs otel-collector`.
+
+### Summarization / embedding features not working
+
+These features require `OPENAI_API_KEY` to be set, or you must point `SUMMARIZATION_API_URL` / `EMBEDDING_API_URL` to an OpenAI-compatible endpoint (e.g., a local Ollama instance with an embeddings model).

-## Claude Code Skill Bridge
-
-The framework's canonical skill root is `~/.config/mosaic/skills/`; Claude Code
-requires registrations under `~/.claude/skills/`. The implementation in
-`packages/mosaic/src/commands/skill.ts` owns only direct-child symlinks whose
-resolved target remains inside the canonical root.
-
-Security invariants:
-
-1. Validate the user-supplied name before filesystem access against
-   `[A-Za-z0-9][A-Za-z0-9._-]*`. Separators, control characters, whitespace,
-   `..`, absolute paths, and leading `-` are invalid; filesystem-derived invalid
-   names are escaped before terminal output.
-2. Never replace a real file, directory, foreign symlink, or live misdirected
-   symlink in the Claude skill directory.
-3. Repair a dangling link only when its lexical target is inside the canonical
-   Mosaic skills root.
-4. Unregister only a symlink pointing inside that root.
-5. Enumerate canonical directories at runtime; never hardcode framework skill
-   names.
-
-`finalizeStage` reconciles after wizard/framework synchronization, and
-`runFrameworkReseed` reconciles after the sync-only `mosaic update` path. A
-foreign conflict is reported but does not prevent unrelated canonical skills
-from registering. Filesystem tests use injected temporary roots in
-`skill.spec.ts`, `finalize-skills.spec.ts`, and `update-checker.reseed.spec.ts`.
-
-M1 intentionally manages Claude Code only. Pi's Mosaic launcher can discover the
-canonical root directly. Codex still relies on the existing full skill-sync
-linker and needs separate parity analysis before this lifecycle API is extended.

 # Migrating to the Federated Tier
 
-> **KBN-101-07 ownership:** This active documentation is a **non-operative KBN-101
-> contract** with no current command authority until KBN-101-00, KBN-101-02, KBN-101-03, KBN-101-05, and KBN-101-06 land and
-> KBN-101-08 activates an exact reviewed release. The commands below describe the produced interface only. Do not run them on the
-> current branch or replace them with direct PostgreSQL, raw SQL, legacy storage migration, or
-> credential-on-argv procedures.
+Step-by-step guide to migrate from `local` (PGlite) or `standalone` (PostgreSQL without pgvector) to `federated` (PostgreSQL 17 + pgvector + Valkey).
 
-## Held future procedure
+## When to migrate
 
-This section is non-operative and grants no current command authority until KBN-101-00, KBN-101-03, and KBN-101-05 land.
+Migrate to federated tier when:
 
-The deployment control plane executes the complete held future procedure, in order: external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `mosaic-db-migrator --verify` → Gateway/Compose readiness. The
-runner is the only attestation producer after its verified TLS, identity, manifest, and schema
-checks. A data importer is never a schema bootstrap, extension installer, repair command, or DDL
-consumer.
+- Scaling from single-user to multi-user deployments
+- Adding vector embeddings or RAG features
+- Running Mosaic across multiple hosts
+- Requires distributed task queueing and caching
+- Moving to production with high availability
 
-## Target material contract
+## Prerequisites
 
-KBN-101-05 obtains the target URL from Vault KV-v2
-`secret-{env}/mosaic-stack/database/importer`, key `url`, and reads its authenticated version from
-the same successful response `data.metadata.version`. A hash or DSN byte sequence is not a
-provider version. The renderer treats URL bytes and provider version as one generation, writes a
-temporary generation directory with fsync plus atomic rename, and creates separate immutable
-consumer mounts. Swarm uses distinct versioned secret/config references. A deployment cannot mix
-generations.
+- Federated stack running and healthy (see [Federated Tier Setup](../federation/SETUP.md))
+- Source database accessible and empty target database at the federated URL
+- Backup of source database (recommended before any migration)

+## Dry-run first
 
-The migrator and importer safe-open URL, provider-version, attestation, and public-key files only
-with `O_RDONLY|O_CLOEXEC|O_NOFOLLOW`; they validate from the opened fd that the file is regular,
-has its expected owner/mode and link count one. The migrator digests only that URL fd for binding,
-then zeroizes/closes it. The importer reads URL bytes once into protected memory, validates the
-signed binding and exact CA before connecting from those same bytes, then zeroizes/closes every
-fd. It neither logs nor exposes a URL/version/attestation/key oracle.
-
-## Produced command interface
-
-After activation and only after approved target preparation, the future interface is:
+Always run a dry-run to validate the migration:
 
 ```bash
-# Deployment control plane has already completed the held runner procedure above.
 mosaic storage migrate-tier --to federated \
-  --target-url-file /run/secrets/mosaic-migrate-target-url \
-  --target-attestation-file /run/mosaic-attestations/migrate-target.v1.json \
+  --target-url postgresql://mosaic:mosaic@localhost:5433/mosaic \
   --dry-run
 ```
 
-The provider-version file is fixed deployment material, not argv. This connecting dry-run consumes its nonce; before an actual copy, the deployment control plane must provide fresh runner verification and a new sealed handoff. The runner uses its migration
-identity; the importer connects only as non-DDL `mosaic_data_importer` and only after all
-pre-connect validation. After verified TLS and before DML it compares PostgreSQL system ID,
-database OID, `current_user`, CA/SPKI, and manifest/schema fingerprints to the artifact.
+Expected output (partial example):
 
-## Required refusals and evidence
+```
+[migrate-tier] Analyzing source tier: pglite
+[migrate-tier] Analyzing target tier: federated
+[migrate-tier] Precondition: target is empty ✓
+  users: 5 rows
+  teams: 2 rows

+[migrate-tier] NOTE: Source tier has no pgvector support. insights.embedding will be NULL on all migrated rows.
+[migrate-tier] DRY-RUN COMPLETE (no data written). 206 total rows would be migrated.
+```
 
-KBN-101-02/-03/-05/-06 must prove, with stable sanitized errors, that no target connection occurs
-for missing/unsafe URL/version/attestation/public-key files; symlink, hardlink, owner, mode, or
-TOCTOU violations; mixed URL/version generations; missing/wrong CA mount; stale/replayed/tampered
-or revoked-key artifacts; provider rotation/revocation; wrong TLS/server/database/role/manifest
-binding; raw `--target-url`; `DATABASE_URL` fallback; runtime/owner identity; consumer leakage;
-or any DDL attempt. Post-connect identity mismatch closes with zero DML/DDL. Tests also prove no
-forwarding, child environment, logging, or error oracle leaks URL/version/key/artifact contents.
+Review the output. If it shows an error (e.g., target not empty), address it before proceeding.
 
-The attestation is credential-free JCS with detached Ed25519 signature and binds issued/expiry,
-nonce, authenticated provider version, exact URL-fd SHA-256, TLS host/port/database, CA/SPKI,
-PostgreSQL system ID/database OID, importer role, manifest/schema, and producer identity. Provider
-version rotation invalidates an old artifact and requires a fresh rendered generation plus runner
-verification.
+## Run the migration
 
-## Actual copy after dry-run
-
-After reviewed dry-run, obtain the required fresh verification/attestation generation, then use:
+When ready, run without `--dry-run`:
 
 ```bash
-# Deployment control plane has supplied fresh runner verification and attestation.
 mosaic storage migrate-tier --to federated \
-  --target-url-file /run/secrets/mosaic-migrate-target-url \
-  --target-attestation-file /run/mosaic-attestations/migrate-target.v1.json \
+  --target-url postgresql://mosaic:mosaic@localhost:5433/mosaic \
   --yes
 ```
 
-The dry-run artifact is terminally replayed and must be rejected; `--yes` bypasses no file,
-generation, signature, TLS, identity, or DDL control.
+The `--yes` flag skips the confirmation prompt (required in non-TTY environments like CI).
 
-## Data boundary and recovery
+The command will:
 
-The importer has only an allowlisted mutable-table DML registry. It has no grant for immutable KBN
-relations, schemas, roles, memberships, extensions, catalogs, or the Drizzle ledger. Source PGlite
-uses its explicit local directory and does not make a PostgreSQL URL fallback valid.
+1. Acquire an advisory lock (blocks concurrent invocations)
+2. Copy data from source to target in dependency order
+3. Report rows migrated per table
+4. Display any warnings (e.g., null vector embeddings)
 
-A failed or ambiguous migration is a control-plane incident: preserve sanitized evidence, retain
-the approved backup/rollback state, and retry only after independent review. Never inspect,
-unlock, repair, or initialize the target with ad hoc SQL or copied credentials.
+## What gets migrated
+
+All persistent, user-bound data is migrated in dependency order:
+
+- **users, teams, team_members** — user and team ownership
+- **accounts** — OAuth provider tokens (durable credentials)
+- **projects, agents, missions, tasks** — all project and agent definitions
+- **conversations, messages** — all chat history
+- **preferences, insights, agent_logs** — preferences and observability
+- **provider_credentials** — stored API keys and secrets
+- **tickets, events, skills, routing_rules, appreciations** — auxiliary records
+
+Full order is defined in code (`MIGRATION_ORDER` in `packages/storage/src/migrate-tier.ts`).
+
+## What gets skipped and why
+
+Three tables are intentionally not migrated:
+
+| Table             | Reason                                                                                          |
+| ----------------- | ----------------------------------------------------------------------------------------------- |
+| **sessions**      | TTL'd auth sessions from the old environment; they will fail JWT verification on the new target |
+| **verifications** | One-time tokens (email verify, password reset) that have either expired or been consumed        |
+| **admin_tokens**  | Hashed tokens bound to the old environment's secret keys; must be re-issued                     |
+
+**Note on accounts and provider_credentials:** These durable credentials ARE migrated because they are user-bound and required for resuming agent work on the target environment. After migration to a multi-tenant federated deployment, operators may want to audit or wipe these if users are untrusted or credentials should not be shared.
+
+## Idempotency and concurrency
+
+The migration is **idempotent**:
+
+- Re-running is safe (uses `ON CONFLICT DO UPDATE` internally)
+- Ideal for retries on transient failures
+- Concurrent invocations are blocked by a Postgres advisory lock; the second caller will wait
+
+If a previous run is stuck, check for advisory locks:
+
+```sql
+SELECT * FROM pg_locks WHERE locktype='advisory';
+```
+
+If you need to force-unlock (dangerous):
+
+```sql
+SELECT pg_advisory_unlock(<lock_id>);
+```
+
+## Verify the migration
+
+After migration completes, spot-check the target:
+
+```bash
+# Count rows on a few critical tables
+psql postgresql://mosaic:mosaic@localhost:5433/mosaic -c \
+  "SELECT 'users' as table, COUNT(*) FROM users UNION ALL
+   SELECT 'conversations' as table, COUNT(*) FROM conversations UNION ALL
+   SELECT 'messages' as table, COUNT(*) FROM messages;"
+```
+
+Verify a known user or project exists by ID:
+
+```bash
+psql postgresql://mosaic:mosaic@localhost:5433/mosaic -c \
+  "SELECT id, email FROM users WHERE email='<your-email>';"
+```
+
+Ensure vector embeddings are NULL (if source was PGlite) or populated (if source was postgres + pgvector):
+
+```bash
+psql postgresql://mosaic:mosaic@localhost:5433/mosaic -c \
+  "SELECT embedding IS NOT NULL as has_vector FROM insights LIMIT 5;"
+```
+
+## Rollback
+
+There is no in-place rollback. If the migration fails:
+
+1. Restore the target database from a pre-migration backup
+2. Investigate the failure logs
+3. Rerun the migration
+
+Always test migrations in a staging environment first.

-# Upgrade Safety & Recovery
-
-How Mosaic protects operator-owned configuration under `~/.config/mosaic` across
-framework upgrades, and how to recover if a projection is ever lost.
-
-A framework upgrade runs `install.sh` in keep-mode (`MOSAIC_INSTALL_MODE=keep`,
-`MOSAIC_SYNC_ONLY=1`) to refresh framework-owned files in place. The incident
-this hardening addresses: an upgrade that silently overwrites or deletes a file
-the operator owns — credentials, personas, a roster, or a generated agent env —
-with no snapshot to fall back to.
-
-Protection is layered. Each layer is independent; a later layer catches what an
-earlier one misses.
-
-## Layer 1 — Manifest-owned sync (prevention)
-
-The single source of truth for ownership is
-[`framework-manifest.txt`](../../packages/mosaic/framework/framework-manifest.txt).
-Both the bash installer and the TypeScript sync path resolve every path against
-this one file (parity is enforced by test), so they can never drift.
-
-- Ownership is **allow-list, deny-wins**: a path is framework-owned only if a
-  `[framework]` glob matches and no `[operator]` carve-out overrides it.
-- **Unknown paths default to operator** (fail-safe): a file the manifest never
-  anticipated is treated as operator-owned and is never pruned.
-- Keep-mode does a non-deleting copy plus an explicit, manifest-scoped prune that
-  only ever iterates framework globs — operator and unknown paths are
-  structurally unreachable by the prune.
-
-Result: a correct upgrade cannot touch operator config at all.
-
-## Layer 2 — Durable pre-update snapshot + verify net (safety + rollback)
-
-Before **any** mutation, the installer snapshots the operator-owned surface that
-exists into:
-
-```
-${XDG_STATE_HOME:-~/.local/state}/mosaic/backups/pre-update-<UTC-timestamp>/
-```
-
-- `0700` directories / `0600` files (`umask 077`, scoped and restored),
-  outside `~/.config/mosaic` and outside any repo.
-- **Fail-open**: a snapshot failure warns but never aborts the upgrade it
-  protects.
-- Retention is `MOSAIC_BACKUP_RETENTION` snapshots (default 5).
-
-After the sync, a **verify net** compares each snapshot file against its target
-and restores (with a loud warning) any operator file the upgrade diverged or
-removed — a divergence means a manifest bug slipped through Layer 1.
-
-Inspect and restore snapshots with the CLI:
-
-```bash
-mosaic restore --list                 # dry-run: enumerate snapshots by timestamp
-mosaic restore --from <UTC-timestamp> # restore the operator surface from one snapshot
-mosaic restore --from <ts> --dry-run  # preview a specific restore without writing
-```
-
-`mosaic restore` reports **counts and relative paths only** — it never emits file
-contents, so a secret in `tools/_lib/credentials.json` is never echoed. Restores
-are confirmation-gated (`--yes` or `MOSAIC_ASSUME_YES`) and write each leaf
-atomically with `O_NOFOLLOW` (a symlink swapped in after the snapshot fails
-closed rather than following out of the managed tree).
-
-## Layer 3 — Regeneration from roster SSOT (recovery)
-
-Some operator files are **derived** and do not need a byte-for-byte snapshot to
-recover — they can be rebuilt from their source of truth. The fleet's per-agent
-generated env projections are the prime case:
-
-- `~/.config/mosaic/fleet/agents/<name>.env.generated` is a deterministic
-  projection of `~/.config/mosaic/fleet/roster.yaml`.
-- The launcher (`start-agent-session.sh`, invoked by
-  `mosaic-agent@<name>.service`) sources that generated projection to establish
-  each agent's identity, runtime, model, and working directory. If it is missing
-  or wrong, the agent cannot launch with its intended identity.
-
-`mosaic fleet regen` rebuilds those projections from the roster SSOT:
-
-```bash
-mosaic fleet regen            # dry-run (default): show what would be rebuilt
-mosaic fleet regen --json     # same, machine-readable
-mosaic fleet regen --write    # rebuild the projections on disk
-```
-
-- **Dry-run by default.** Nothing is written until you pass `--write`.
-- **Deterministic and idempotent** — the projection is a pure function of the
-  roster, so repeated `--write` runs produce byte-identical files.
-- **Projection-only. It never restarts an agent.** Recovery order forbids
-  restart-before-verify; `regen` has no path to systemd lifecycle at all.
-- **It rebuilds only `<name>.env.generated`** — it never writes, relocates, or
-  deletes the operator-owned `.env` / `.env.local` surface.
-- It **validates the roster the same way `reconcile` does** (persona resolution
-  and protected-class tool-policy match), so a hand-edited or corrupt roster is
-  rejected rather than projected, and a `--write` takes the shared reconcile
-  lock so it cannot race a concurrent reconcile.
-- Output is **paths and counts only** — the rendered `KEY=value` body is never
-  echoed.
-
-`regen` uses the exact same roster→env mapping as `mosaic fleet reconcile`, so a
-recovered projection matches what a normal reconcile would have written.
-
-## Recovery runbook — wiped `fleet/agents/*.env.generated`
-
-If an upgrade (or a manual mistake) has left an agent without its generated
-projection, **do not restart the unit first** — a launch against a missing
-projection fails closed, and any stale state must be corrected before restart,
-not after.
-
-1. **Prefer a snapshot restore if one exists** (byte-exact operator state):
-
-   ```bash
-   mosaic restore --list
-   mosaic restore --from <UTC-timestamp>
-   ```
-
-2. **Otherwise regenerate the derived projections from the roster SSOT:**
-
-   ```bash
-   mosaic fleet regen            # confirm the plan (create vs rebuild per agent)
-   mosaic fleet regen --write    # rebuild fleet/agents/<name>.env.generated
-   ```
-
-3. **Verify each unit will resolve the intended runtime/workdir _before_ any
-   restart.** The unit sets **no** `EnvironmentFile=` — it launches from a minimal
-   environment and `start-agent-session.sh` sources `.env.generated` itself, so
-   verify the generated file directly and confirm the launcher path:
-
-   ```bash
-   # Confirm fleet/agents/<name>.env.generated exists and carries the intended
-   # MOSAIC_AGENT_* values (name, runtime, model, workdir, socket).
-   test -f ~/.config/mosaic/fleet/agents/<name>.env.generated
-   # Confirm the unit launches the session script that reads it.
-   systemctl --user cat mosaic-agent@<name> | grep ExecStart
-   ```
-
-4. **Only then restart, one unit at a time:**
-
-   ```bash
-   systemctl --user restart mosaic-agent@<name>
-   ```

-### Claude Code Skill Registration
-
-Mosaic stores canonical skills under `~/.config/mosaic/skills/`. Claude Code scans
-`~/.claude/skills/`, so Mosaic maintains one symlink per skill between those
-directories.
-
-```bash
-mosaic skill list
-mosaic skill register <name>
-mosaic skill unregister <name>

-
-- `register` is idempotent and repairs a dangling Mosaic-owned link. Names use
-  the safe grammar `[A-Za-z0-9][A-Za-z0-9._-]*`; files, directories, foreign
-  symlinks, path traversal, absolute paths, and names beginning with `-` are
-  refused.
-- `unregister` is idempotent when no entry exists. It removes only symlinks that
-  point inside `~/.config/mosaic/skills/`; foreign entries are never removed.
-- `list` reports `registered`, `unregistered`, `dangling`, `foreign`,
-  `foreign-dangling`, or `misdirected` for each canonical or Claude entry.
-
-Install, wizard finalization, and `mosaic update` framework re-seeding reconcile
-every canonical skill automatically. A skill directory added after initial
-setup therefore receives its Claude bridge without a per-skill code change or
-manual `ln -s`. If Claude Code is already running, use `/reload-skills` or start
-a new session after registration so its in-process skill registry rescans.
-
-This command group is Claude-only in M1. Pi can consume Mosaic's canonical skill
-root through its Mosaic launcher configuration and does not need this Claude

 ## Amendment record
 
-### 1.0.0-rc.16 — Current generic storage-wrapper authority closure
-
-- **Current-source truth:** `packages/storage/src/cli.ts` currently shells `storage migrate --run` directly to `pnpm --filter @mosaicstack/db db:migrate` through `execSync`; no `mosaic-db-migrator` executable exists. README and user-guide command guidance therefore remove that command and any runner-delegation claim. The current wrapper is legacy N-1, uncertified, non-operative, and MUST NOT be invoked pending KBN-101-02/-03/-06/-08 activation.
-- **Future-only boundary:** future schema migration remains non-operative and follows external bootstrap → TLS/roles → runner `--run` → runner `--verify` → readiness; tier copy uses only the separately held secure migrate-tier route.
-- **Unmaskable semantic/source-consistency evidence:** before inventory, ownership, or status masking, -06 fails the exact former README commented code-fence generic-wrapper form and exact user-guide executable generic-wrapper form. Its source-consistency test proves the direct-Drizzle `execSync` target and absent runner bin, so any documentation describing current wrapper delegation to the runner fails.
-- **Non-effect:** prior runner, legacy-CI, Compose, production-secret, attestation, pgvector, manifest, lock, TLS, activation, and serial-gate closures remain unchanged.
-
-### 1.0.0-rc.15 — Held runner and legacy-CI authority closure
-
-- **Held runner only:** Current operator documents cannot advertise `mosaic-db-migrator --run|--verify` as executable. The sole passing future form is one `Held future procedure` Markdown section, bounded through its next equal-or-higher heading, that explicitly says non-operative/no-current-command-authority, names KBN-101-00/-03/-05, and preserves external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `mosaic-db-migrator --verify` → Gateway/Compose readiness. Any runner hit outside that section fails before inventory/ownership/status masking.
-- **PGlite/current-CI boundary:** Fleet backlog current behavior is PGlite-only; PostgreSQL CLI/runner authority remains held until activation. README classifies the checked-in direct `db:migrate` CI job as active legacy N-1, uncertified, non-authorizing as an operator route, and pending KBN-101-06 removal; it is a known direct-DDL exception against an isolated disposable CI database, not approved ordinary behavior. The -06 fixture asserts every required status term and rejects ordinary-authority presentation.
-- **Non-effect:** prior Compose, production-secret, attestation, pgvector, manifest, lock, TLS, activation, and serial-gate closures remain unchanged.
-
-### 1.0.0-rc.14 — Current Compose and production-secret route closure
-
-- **Current developer boundary:** `README.md` and `docs/guides/dev-guide.md` permit only in-process PGlite data-layer work and explicitly selected non-PostgreSQL Compose services. Gateway/Web local start is held because the current unguarded loader can inherit a daemon/project PostgreSQL DSN and reach runtime DDL; KBN-101-02 must reject it before connection. The current PostgreSQL Compose mount is legacy/unqualified; PostgreSQL and federated activation are held until KBN-101-00/-03/-05 and then follow external bootstrap → TLS/roles → runner `--run` → `--verify` → Gateway/Compose readiness.
-- **Production boundary:** `docs/guides/deployment.md` is non-operative until the KBN-101-05 renderer-backed process-exec or `LoadCredential` interface exists. It contains no active production environment-file, monorepo auto-load, credential export/argv, or secret-activation lifecycle route; future units must preserve generation-pinned Vault consumer isolation.
-- **Unmaskable semantic negatives:** -06 fails the exact former README/dev/deployment Compose-first sequences and every production `.env`, `EnvironmentFile=`, credential export/argv, or restart-as-secret-activation fixture before owned/status/normative classification. The held PGlite/non-PostgreSQL route and future ordered activation are the only passing fixtures.
-
-### 1.0.0-rc.13 — Federation-MILESTONES indirect-startup closure
-
-- **Complete operator inventory:** `docs/federation/MILESTONES.md` is exclusively KBN-101-07 and an exact KBN-101-06 `operator-document` `status-only` record. Its former `pgvector extension installed + verified on startup` wording is superseded and forbidden; it authorizes no current DDL, Compose/init, or runtime/startup path.
-- **Unmaskable semantic negative:** before inventory disposition, the scanner fixture proves that exact former wording fails. The only passing status-only sequence is external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `mosaic-db-migrator --verify` → Gateway readiness.
-
-### 1.0.0-rc.12 — Deployable importer generation and indirect-DDL-route closure
-
-- **Authenticated generation:** KBN-101-05 owns one canonical Vault KV-v2 importer record, `secret-{env}/mosaic-stack/database/importer` key `url`, with its version taken only from the same successful `data.metadata.version` response. Value plus provider version are one generation, never inferred from DSN bytes. The renderer creates separate immutable `0400` URL/version copies for migrator `10003:10003` binding-only access and importer `10002:10002` access; it uses fsync/atomic generation replacement for Compose and distinct versioned secret/config references for Swarm, so deployment cannot mix generations.
-- **Bounded consumers:** importer alone receives its URL/version, CA at `DATABASE_TLS_CA_CERT_PATH`, pinned public key, and read-only attestation; migrator receives its own migration URL/CA, the URL/version only for no-connect/no-export binding, attestation output, and the root-wrapper-only private key. Safe fd open/fstat/digest/zeroize/close semantics, a privileged producer-only-to-importer-only attestation handoff controller (verify, exact-byte copy, fsync/atomic rename, `10002:10002` `0400` seal, then importer start), no shared writable file, no logging/oracle, provider rotation/revocation, CA/mount, consumer-isolation, and symlink/hardlink/owner/mode/TOCTOU negatives are mandatory.
-- **Indirect-DDL closure:** `docs/federation/SETUP.md` is non-operative until KBN-101 activation and documents only external bootstrap → TLS/roles → runner `--run` → `--verify` → Gateway readiness. The -06 scanner performs unsuppressible semantic checks for automatic first-boot/startup extension/schema/migration language, Compose-up-before-runner, and init-script authority; the former SETUP wording fails and the remediated sequence passes.
-
-### 1.0.0-rc.11 — Target-bound importer attestation and exhaustive operator-route closure
-
-- **Target-bound proof:** trusted `mosaic-db-migrator --verify` now produces the atomic, credential-free `migrate-target.v1.json` JCS/Ed25519 artifact from a runner-only root-owned signing-key reference; the importer receives only pinned public verification keys and the artifact. Its signed v1 fields bind issued/expiry/nonce, exact secret version and SHA-256 of high-entropy target-file bytes, canonical TLS host/port/database, CA/SPKI, PostgreSQL system identifier/database OID, expected importer role, manifest/schema fingerprints, and producer invocation/build/image/correlation. No DSN, username, password, credential bytes, or signing key enters the artifact, importer, runtime, logs, or output.
-- **Fail-closed importer:** `mosaic storage migrate-tier` requires both `--target-url-file /run/secrets/mosaic-migrate-target-url` and `--target-attestation-file /run/mosaic-attestations/migrate-target.v1.json`. Before target connection it validates files, signature/key/expiry/replay, secret version/digest, TLS/CA/role/manifest bindings and opens/digests/connects from the same in-memory URL bytes. After verified TLS but before transaction/DML it matches server ID, database OID, `current_user`, CA/SPKI, and manifest/schema; failure distinguishes zero connection from connection/zero-DML and DDL remains impossible. Rotation overlap/revocation, atomic rename, replay cache, secret rotation invalidation, and wrong/substituted/stale/tampered/file-change tests are mandatory.
-- **Closed documentation surface:** KBN-101-06 inventories every current non-normative scanner hit, including `docs/guides/user-guide.md` and status-only `docs/federation/TASKS.md`; the latter is historical and cannot authorize DDL. The legacy `storage migrate` tier-copy syntax is unavailable. `storage migrate` is schema-wrapper delegation only; secure tier data copy is `migrate-tier`. Exact KBN PRD/contract/shared/task paths may be `normative-contract` scan class but are still scanned and cannot mask executable instructions. The normative detail remains [`KBN-101-DB-ROLE-SPLIT.md`](./KBN-101-DB-ROLE-SPLIT.md).
-- **Non-effect:** pgvector closure, manifest, lock, role graph, TLS, activation, and KBN-100/KBN-105 serial gates are unchanged.
-
-### 1.0.0-rc.10 — PostgreSQL-valid untrusted pgvector owner and active migrate-tier closure
-
-- **Valid extension authority:** PostgreSQL 17 + pgvector 0.8.2 `vector` is untrusted (`trusted` absent; `relocatable=true`), so `mosaic_extension_owner` is exactly `NOLOGIN SUPERUSER`, not `NOSUPERUSER`. It is dedicated solely to `mosaic_extensions`, `vector`, and owner-bearing extension members; `rolcanlogin=false`, `rolsuper=true`, zero members, no runtime credential/Vault secret, and no app-container delivery are catalog and deployment proof. An externally controlled audited bootstrap-superuser session alone `SET ROLE`s for extension CREATE/UPDATE/SET SCHEMA, then `RESET ROLE`; fresh and shadow paths do so, while in-place existing work requires exact pre-existing `extowner`.
-- **Explicit superuser exception:** `GRANT`/`REVOKE` cannot privilege-limit a superuser. The containment is dedicated identity, no login, no membership, external control plane, audit, independent review, backup/rollback, and maintenance window—not a false least-privilege claim. Runtime, migrator, schema owner, importer, and every service role cannot assume the role or alter/update/drop/change extension membership. Managed targets without this exact role are ineligible unless a versioned provider-owned extension-owner profile is independently approved.
-- **Active secure data-migration route:** `docs/guides/migrate-tier.md` is exclusively KBN-101-07, is active rather than historical, and specifies runner-prepared/verified PostgreSQL destination plus a dedicated non-DDL importer. KBN-101-02 freezes `--target-url-file /run/secrets/mosaic-migrate-target-url`, never credential argv; raw `--target-url`, `DATABASE_URL` fallback, runtime owner, missing/unsafe file, wrong mode, and DDL all fail before target connection/DDL. KBN-101-06 inventory/matrix records the route and exact secure fields, then tests its finite operator-document closure.
-- **Non-effect:** manifest, lock, `mosaic` application schema, TLS, activation, and KBN-100/KBN-105 serial gates remain unchanged. The normative detail remains [`KBN-101-DB-ROLE-SPLIT.md`](./KBN-101-DB-ROLE-SPLIT.md).
-
-### 1.0.0-rc.9 — KBN-101 extension-schema boundary, disjoint manifests, and scanner mechanics
-
-- **Extension schema owner:** `mosaic_extension_owner`, not `mosaic_schema_owner`, creates and owns `mosaic_extensions`, `vector`, and extension-member objects. The external bootstrap actor `SET ROLE`s for fresh creation or approved-owner relocation, then `RESET ROLE`s; rc.10 replaces the earlier membership wording with the PostgreSQL-valid zero-member superuser exception. Schema owner has only `USAGE` for legacy type resolution—never ownership, `CREATE`, `ALTER`, `DROP`, member change, or default-privilege authority. Runtime, migrator, and schema owner must fail catalog and direct DDL denials; shadow/resume/rollback repeat the owner/default-privilege proof.
-- **Exclusive delivery DAG:** KBN-101-00…09 now has a complete, nonoverlapping exact file/glob manifest with named tests/evidence. The runner mapping is exactly `"mosaic-db-migrator": "./dist/cli.js"` and image `ENTRYPOINT ["mosaic-db-migrator"]`; `packages/storage/src/{cli,migrate-tier}.ts` belongs only to -02, and -07 is documentation only. -08/-09 own evidence paths only. -00…07 are prepared artifacts; the immutable N-1 image remains live until -08 atomic activation, so no independently deployed intermediate can bypass runtime controls.
-- **Mechanical classifier:** -06 owns the exact scanner, inventory fixture, command-matrix harness, and CI wiring. Inventory records pin path/class/owner/disposition/allowed tokens/rationale/expiry/review revision; unknown, duplicate-owner, ownerless, missing-path, invalid allowlist, and historical-category masking fail. The architecture plan's operative direct `db:migrate` is replaced by sole-runner guidance rather than hidden under a historical category.
-- **Non-effect:** manifest v1, lock, `mosaic` application-schema ownership, TLS, activation, KBN-100/KBN-105 serial gates, and all earlier canon decisions remain unchanged. The normative detail remains [`KBN-101-DB-ROLE-SPLIT.md`](./KBN-101-DB-ROLE-SPLIT.md).
-
-### 1.0.0-rc.8 — KBN-101 finite authority, executable runner, and pgvector-owner remediation
-
-- **Finite authority closure:** KBN-101-06 classifies every current executable source/script/package bin, operator document, and deploy manifest by exact path; unclassified current hits fail. Byte-immutable historical SQL, PGlite-only routines, negative-test literals, vendored/generated artifacts, and clearly labeled historical reports are exact-path/category reviewed allowlists only. `packages/db/src/index.ts` loses its public `runMigrations` export with a direct-import/compile negative; `docs/fleet/backlog-conventions.md` and `docs/PERFORMANCE.md` lose first-use/direct-Drizzle/Gateway-startup migration instructions and carry runner/readiness route negatives. A token scan is only input to the classifier, never proof of authority.
-- **Executable exclusive cards:** KBN-101-03 alone publishes `mosaic-db-migrator` from `packages/db/package.json`/`src/cli.ts`, owns `docker/db-migrator.Dockerfile`, and keeps `{runner,config.dto,manifest,identity,tls}` private, with exact `--run|--verify|--help`, env-only input, stable exits, and command tests. KBN-101-00 alone owns `infra/pg-bootstrap/roles.sql`, `infra/pg-bootstrap/extensions.sql`, `infra/pg-bootstrap/README.md`, plus bootstrap tests. KBN-101-05 alone owns `tools/db/render-postgres-secrets.ts`, renderer tests, and Compose/Portainer/Swarm/two-gateway declarations, consuming the versioned bootstrap interface. No card overlaps renderer/bootstrap/deployment ownership.
-- **Extension-owner transition:** `mosaic_extension_owner` is a dedicated NOLOGIN role whose membership/credentials never reach services; the external bootstrap actor alone may `SET ROLE` during bootstrap. Fresh vector and member objects retain that owner. PostgreSQL has no supported extension-owner alteration: approved-owner existing extension relocation validates `pg_extension.extowner`, members/schema/version and uses tested `ALTER EXTENSION ... SET SCHEMA`; legacy runtime-owned extension fails closed to a controlled shadow database migration with backup, evidence, quiesce/final delta, atomic switch, and read-only rollback window. No catalog mutation, ownership adoption, or `DROP CASCADE` is permitted. Runtime/migrator/schema-owner extension ALTER/DROP/member-update denial is mandatory.
-- **Non-effect:** manifest v1, lock namespace, role/search-path, relocation/TLS/activation, KBN-100/KBN-105 serial gates, and all retained canon decisions are strengthened, not weakened. The normative detail remains [`KBN-101-DB-ROLE-SPLIT.md`](./KBN-101-DB-ROLE-SPLIT.md).
-
-### 1.0.0-rc.7 — KBN-101 complete current-path, relocation, and two-gateway remediation
-
-- **Finite current-path closure:** static inventory and the `DATABASE_URL`-only-before-connect/DDL denial matrix now explicitly include Gateway's former temporary-table pgvector test (runner-prepared persistent read/query-only fixture), `docker/init-db.sql` retirement, `migrate-tier.ts` runner/bootstrap-only guidance, and the active two-gateway harness. The harness is migrated, not retired: `postgres-a/b → mosaic-db-migrator-a/b → gateway-a/b`, each with isolated URL/CA material, verified readiness, SANs, and positive/negative TLS evidence.
-- **Executable relocation:** KBN-101-03 exclusively owns `schema.ts`, Drizzle snapshots/journal/generated relocation and exact tests. All future application declarations use exported `pgSchema('mosaic')`; immutable historical SQL runs only in trusted legacy `public`. `vector` is fixed in non-writable `mosaic_extensions`, with exact catalog relocatability/version eligibility, explicit type/operator qualification, catalog-class ordering, unknown-object fail-closed behavior, clean/current-public/partial/reverse rollback tests, and an N-1 release order.
-- **Bound deployment ownership:** `mosaicstack/stack` KBN-101-00/05 owns current Compose, Portainer, two-gateway, bootstrap renderer/templates, UID/GID declarations, and rendered validation. Gateway is fixed to `10001:10001`; PostgreSQL UID/GID is image-inspected and frozen only after digest pinning. Exact secret paths, atomic renderer behavior, Compose/Swarm targets/modes, Gateway/PostgreSQL leaf separation, and two-pair TLS failure evidence are required. Mosaic deployment control plane/Jason is the named activation authority; environment IaC/Vault supplies versioned input only.
-- **Correct traceability:** REQ-03 maps to role/schema/search-path, REQ-04 to TLS, REQ-05 to post-KBN-100 immutability, REQ-06 to rollout/rollback, and REQ-07 to the KBN-101 → KBN-100 → KBN-101 → KBN-105 sequence. No prior manifest/lock/role/DAG/activation decision is weakened.
-
-### 1.0.0-rc.6 — KBN-101 closed DDL/TLS/ledger activation remediation
-
-- **Choice:** `mosaic-db-migrator` is the sole application/CI/test PostgreSQL DDL control plane. Every legacy entrypoint is routed or denied, rejects `DATABASE_URL`-only before connection/DDL, and `db:push` is unavailable outside an allowlisted disposable developer target. The runner holds one `max:1` session with fixed `pg_try_advisory_lock(1297044289,1262636593)` across preflight through release.
-- **Exact ledger:** manifest v1 canonically serializes journal logical index/tag and SHA-256 of exact shipped migration bytes. It maps each observed ledger hash to one tuple; physical insertion order is non-normative, while missing/unknown/duplicate/ambiguous/corrupt/stale states fail closed. Shipped `0009` bytes remain unchanged; a missing/effects-absent `0009` runs normally, an applied-late hash maps normally, and partial/full effects with missing hash require backup restoration or separately reviewed repair—not manual adoption.
-- **TLS/search path:** operator/IaC owns CA and server leaf lifecycle, exact compose/Swarm secret mounts, server TLS activation, service-DNS SANs, verified-TLS readiness, transition, CA overlap rotation, and rollback. Runtime/migrator use `verify-full`; PGlite is not PostgreSQL TLS evidence. Application sessions use only `pg_catalog,mosaic`; no URL/config-derived identifier reaches SQL.
-- **Safe release:** cards 00–07 land prepared but inactive; owner-runtime deployments remain N-1. Mosaic control plane/Jason alone authorizes one atomic TLS/roles → runner → readiness → runtime activation or rollback. No runtime-operator compatibility switch, bypass, plaintext interval, or force-on-red exists; all temporary support is removed before KBN-101-08.
-- **Non-effect:** role graph, immutable certification after KBN-100, KBN-105 gate, rc.5’s preserved rc.4 SI-001 invariants, and all KCR-001–016 decisions remain unchanged. Exact detail is normative in [`KBN-101-DB-ROLE-SPLIT.md`](./KBN-101-DB-ROLE-SPLIT.md).
-
-### 1.0.0-rc.5 — KBN-101 role/connection split
-
-- **Choice:** PostgreSQL `standalone` and `federated` runtime uses `DATABASE_URL` only as a non-owner `mosaic_runtime` login; an explicit migration phase uses `DATABASE_MIGRATION_URL` only as `mosaic_migrator`, which `SET ROLE`s to non-login `mosaic_schema_owner` for DDL. Local PGlite remains an explicit embedded exception.
-- **No fallback / no startup DDL:** missing migration URL fails the migration phase; it never falls back to runtime URL/default/config. Gateway replicas do not run migrations. An advisory-locked migration phase verifies the exact ordered Drizzle ledger fingerprint before replicas may become ready.
-- **Privilege model:** non-login `mosaic_platform_database_owner` is outside application paths; `mosaic_schema_owner` owns only application/ledger schemas. `mosaic_runtime` has only `mosaic_runtime_capability`, owns no object/schema, cannot assume owner/migrator, has no TEMPORARY privilege, has only read access to the Drizzle ledger, and must fail startup if effective identity, unsafe attributes, authenticated TLS, search path, schema version, grants, or immutable relation privileges differ from the frozen contract. `task_events`, `artifacts`, `task_checkpoints`, `task_checkpoint_artifacts`, and `approval_decision_artifacts` grant runtime only INSERT/SELECT; KBN-100 retains RESTRICT/no-cascade semantics.
-- **Non-effect:** rc.4 SI-001 candidate-key/FK order and all KCR-001–016 tenancy, SOT, proposal-audit, approval, fence, recovery, no-cascade, endpoint, and wire invariants are unchanged. This amendment neither creates roles/secrets nor changes production deployment.
-- **Gate:** KBN-101’s role/schema-boundary foundation certificate, Vault/redaction/rotation, N-1/rollback, and independent security GO are mandatory before KBN-100. After KBN-100 creates the immutable relations, KBN-101 real deployed-role immutable-operation certification plus Ultron GO is mandatory before KBN-105; synthetic test-role success alone is insufficient. Exact implementation detail is normative in [`KBN-101-DB-ROLE-SPLIT.md`](./KBN-101-DB-ROLE-SPLIT.md).

 - **Rationale:** mission `id` remains globally unique, while the composite candidate key makes the frozen tenant-safe generic mission relations valid. `artifacts` and `approval_decisions` are polymorphic exactly-one-target records and do not consistently carry `project_id`; widening both children would unnecessarily broaden v1 and its target semantics.

-- **Changed docs:** `docs/PRD.md`, `docs/SITEMAP.md`, `docs/native-kanban-sot/{INDEX.md,KBN-101-DB-ROLE-SPLIT.md,SHARED-CONTRACT.md,TASKS.md}`, and `docs/scratchpads/771-kbn101-db-role-split.md` (300 additions / 25 deletions).
-- **Reviewed inputs:** issue #771; current DB/Gateway/storage/config/wizard/installer/compose/Portainer/CI sources; all current migration/DDL references; KBN-010, rc.4/rc.5 shared contract, requirements/canon, KBN-100 #769 branch context, and the final scratchpad.
-- **Repository/provider state:** not modified. The pre-existing `.mosaic/orchestrator/*` dirt was not touched.
-
-The role graph itself is sound in principle: a NOLOGIN platform database owner, separate NOLOGIN schema owner, NOINHERIT migrator which explicitly `SET ROLE`s, and runtime membership only in a capability role with `SET FALSE` does not create circular privilege or application-created login roles. The split of foundation certification before KBN-100 and immutable-operation certification after KBN-100 is also correctly ordered.
-
-## Findings
-
-### HIGH — DDL/migration control plane is not closed at every current entrypoint
-
-The contract requires an explicit, locked migration phase and forbids Gateway/runtime DDL (`KBN-101-DB-ROLE-SPLIT.md:34-39`), but its KBN-101-02 result merely says migration-capable commands use the migration DTO (`:109`). It does not prohibit or route every existing bypass through that one command.
-
-Current bypasses include:
-
-- `runMigrations()` falls back from an argument to `DATABASE_URL` and a hard-coded URL (`packages/db/src/migrate.ts:24-35`), while `drizzle.config.ts` likewise uses `DATABASE_URL` plus a default (`packages/db/drizzle.config.ts:3-9`).
-- Package scripts expose direct `drizzle-kit migrate` **and** `drizzle-kit push` (`packages/db/package.json:23-26`); `db:push` bypasses the planned journal/fingerprint/lock entirely.
-- `mosaic storage migrate --run` shells out to the direct `db:migrate` script (`packages/storage/src/cli.ts:413-452`).
-- The federated integration test can create types, tables, and indexes directly against `DATABASE_URL` and intentionally operates without a Drizzle ledger (`packages/db/src/federation.integration.test.ts:28-30,46-134`).
-
-**Failure mode:** a runtime or CI environment with only `DATABASE_URL`, or an operator invoking an existing command, can apply unverified DDL outside the lock, `SET ROLE` preflight, exact-ledger gate, and deployment sequencing. This breaks the requested fail-closed split even if Gateway startup is repaired.
-
-**Required remediation:** amend KBN-101-02/03/06 to enumerate these entrypoints and make the dedicated migrator runner the only PostgreSQL DDL path. Production-like `db:push` must be removed/blocked; `db:migrate`, `storage migrate --run`, and migration tests must invoke the same migration runner with `DATABASE_MIGRATION_URL`, lock, identity preflight, and ledger verification. Tests needing schema must consume a pre-migrated disposable database, or be explicitly run only by that migration phase. Add negative tests showing each command refuses `DATABASE_URL`-only execution and cannot reach DDL.
-
-### HIGH — TLS requirement has no deployable server/bootstrap contract
-
-The contract correctly requires a mounted CA and hostname-verified TLS (`KBN-101-DB-ROLE-SPLIT.md:25,28,93-95`). However KBN-101-05 promises only a “migration phase and secret binding boundary” (`:112`), not PostgreSQL server TLS, certificate issuance/SANs, CA distribution, startup ordering, or the fresh/existing-database bootstrap trust path.
-
-Current standalone and federated compose expose plain PostgreSQL with no server TLS configuration or CA mount (`docker-compose.yml:2-14`; `docker-compose.federated.yml:27-44`). The Portainer test stack passes a single plaintext in-network URL and uses the same database login for Gateway and database bootstrap (`deploy/portainer/federated-test.stack.yml:51-60,110-117`).
-
-**Failure mode:** enforcing the mandatory CA makes current local standalone/federated topologies unable to start; relaxing it to make bootstrap work silently violates K101-REQ-03. A first database cannot be safely migrated until the server certificate, its SAN for the actual service/DNS name, and trusted CA are provisioned, but this lifecycle is not owned or tested.
-
-**Required remediation:** add a concrete KBN-101-00/05 TLS bootstrap sub-contract: issuer/CA owner; server key/cert and SAN inputs; secure storage/mount permissions; `postgresql.conf`/container TLS enablement; migration and runtime CA mounts; hostname used by each compose/Swarm service; readiness only after TLS authentication; CA overlap rotation; and an existing-database transition. Require a disposable standalone and federated/Swarm test to prove verified TLS succeeds and missing CA, wrong CA, wrong SAN, and `sslmode` downgrade fail before readiness. Do not merge KBN-101-05 with an implicit plaintext exception.
-
-### HIGH — exact ledger fingerprint and historical 0009 repair are underspecified for existing databases
-
-The contract requires an “ordered complete set” and rejection of out-of-order rows (`KBN-101-DB-ROLE-SPLIT.md:36-38`), but does not define the canonical serialized tuple, ledger ordering source, or safe upgrade rule for a historical ledger. The current ledger stores only `id`, `hash`, and `created_at` (`packages/db/src/migrate.ts:70-82,105-107`). Its journal is demonstrably non-monotonic: `0008` has `when=1776822435828`, followed by `0009` at `1745280000000` (`packages/db/drizzle/meta/_journal.json:62-79`); the existing PostgreSQL runner documents that this causes skipping (`packages/db/src/migrate.ts:29-35`).
-
-**Failure mode:** an implementation can either reject a legitimate historical database after correcting 0009, or accept a reordered/duplicated ledger because no precise comparison rule exists. A count/hash-set implementation would fail to detect the condition that this contract explicitly calls unsafe; physical `id` order is not an adequate substitute after historical repair.
-
-**Required remediation:** freeze a versioned manifest algorithm before implementation: canonical record fields (at least journal index/tag, corrected logical order, migration content hash, and an explicit migration-manifest version), canonical byte serialization, SHA-256 input, and exact observed-ledger mapping. State whether physical ledger insertion order is normative; if not, compare hash-to-manifest tuples rather than timestamps. Add an idempotent migrator-only 0009 existing-database remediation/reconciliation procedure with backup/rollback evidence. Require clean, pre-0009, 0009-skipped, 0009-applied-late, duplicate, unknown, missing, corrupt-pair, and stale-replica cases. No manual ledger insertion is an acceptable production recovery path.
-
-### MEDIUM — advisory-lock namespace is collision-prone and lacks a fixed identifier contract
-
-The specified lock is `pg_try_advisory_lock(hashtext('mosaic-schema-migration-v1'))` (`KBN-101-DB-ROLE-SPLIT.md:34`). `hashtext` produces a 32-bit key. Session ownership/crash behavior is otherwise correctly stated (one session, same-session release, connection-close release), but an unrelated database user can accidentally collide or deliberately hold the key and force `DATABASE_MIGRATION_LOCKED`.
-
-**Failure mode:** avoidable migration denial of service in a shared PostgreSQL database. The current repository already uses separate `hashtext` advisory-lock names for migrate-tier, demonstrating the need for a documented namespace rather than a collision-prone implicit one.
-
-**Required remediation:** freeze a two-int advisory-lock namespace (fixed documented class/object values) or a documented 64-bit `hashtextextended` key with fixed seed; keep acquisition, migration, verification, and release on the single `max:1` migrator session. Add tests for concurrent migration, connection loss/crash release, readiness while the lock holder is active, and an unrelated lock-key non-interference case.
-
-### MEDIUM — identifier safety and `search_path` verification need executable constraints
-
-The contract rightly requires `pg_catalog, <mosaic_application_schema>` and rejects writable paths (`KBN-101-DB-ROLE-SPLIT.md:54,70-77`), but uses dynamic placeholders for database/schema and does not state how migration/bootstrap SQL will avoid identifier interpolation. Existing code has raw-SQL facilities (`packages/storage/src/migrate-tier.ts` uses `.unsafe`), so this is not merely theoretical.
-
-**Failure mode:** a future operator-configured database/schema value that reaches bootstrap or `SET search_path` through raw string construction can inject DDL, or a pooled connection can retain a mutable search path.
-
-**Required remediation:** require fixed allowlisted identifiers or server-side identifier quoting (`format('%I', ...)`) only; never interpolate URL/config values into SQL. Set and verify the trusted path per connection/session before any query (`SET LOCAL` inside transactions where applicable), forbid `public`/`$user` additions, and add injection-shaped identifier and pooled-connection reset negatives. Include this in KBN-101-00/01 tests.

-## Acceptance and threat traceability
-
-| Requirement / threat | Review result | Evidence or blocking finding |
-| --- | --- | --- |
-| K101-REQ-01 / AC-K101-01 split runtime/migration URLs | Partial | Role/DTO boundary is coherent; HIGH DDL-path finding requires all current commands to be closed. |
-| K101-REQ-02 / AC-K101-02 explicit migration/readiness | Blocked | HIGH ledger definition and HIGH DDL-bypass findings. |
-| K101-REQ-03 / AC-K101-03 least privilege, TLS, grants | Partial | Role model, default privileges, ledger read-only, TEMP/function checks are well specified (`KBN-101...:47-56,70-79`); HIGH TLS bootstrap and MEDIUM identifier constraints remain. |
-| K101-REQ-04 / AC-K101-04 immutable relations | Correctly deferred | KBN-101-09 after KBN-100 is the correct serial gate (`KBN-101...:58-66,115-118`); no synthetic-only certification claim found. |
-| K101-REQ-05 / AC-K101-05 N-1, secrets, rollback | Partial | No owner-runtime exception and rollback keeps migration URL out of Gateway (`:83-95`); deployable TLS and full command inventory are missing. |
-| K101-REQ-06 / AC-K101-07 KBN gates and DAG | Structurally sound | DAG is acyclic: 00→01/{03}; 02→06; 00/01/03→05; 00/04/05/06→07→08→KBN-100→09→KBN-105. KBN-100’s current branch contains docs-only baseline tracking, not schema implementation. |
-| T: runtime DDL / migration fallback | Blocked | HIGH finding 1. Current Gateway/storage, CLI, direct Drizzle scripts, and integration DDL require explicit closure. |
-| T: race/crash/readiness | Partial | Same-session nonblocking lock and replica-unready rules are present (`:34-38`); lock namespace remediation required. |
-| T: immutable evidence rewrite | Correctly staged | Explicit INSERT/SELECT-only matrix and RESTRICT retention are retained; proof is properly after table creation. |
-| T: secret leakage / TLS downgrade | Partial | Redaction and distinct Vault paths are specified (`:93-97`), but no server TLS/bootstrap implementation contract exists. |
-
-## Unresolved assumptions
-
-1. `standalone` and `federated` are the complete PostgreSQL production-like set (K101-A1).
-2. Each eligible deployment can execute a dedicated migration Job/one-shot phase (K101-A2).
-3. Vault path names are targets, not verified existing paths; deployment ownership remains to be established.
-4. PostgreSQL 17 is available for the selected membership and advisory-lock implementation.
-5. The required server-side TLS issuer/certificate lifecycle and Swarm/compose secret transport have not been decided; this is blocking, not a permissible implicit plaintext bootstrap.
-6. Historical databases containing the 0009 journal/ledger anomaly have no frozen reconciliation procedure.
-
-## Independent test and consistency evidence
-
-Read-only checks run in this review:
-
-| Check | Result |
-| --- | --- |
-| `git diff --check origin/main...da742ca2...` | PASS |
-| `pnpm exec prettier --check` on all seven changed docs | PASS |
-| `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json` | PASS |
-| `docker compose -f docker-compose.yml config --quiet` (isolated test ports) | PASS |
-| `docker compose -f docker-compose.federated.yml --profile federated config --quiet` (isolated test ports) | PASS |
-| Static journal inspection | FAILS the required monotonic ordering premise: 0008 → 0009 `when` decreases; current runner documents skipping behavior. |
-| Static DDL-entrypoint inventory | Found direct Drizzle scripts, storage CLI shell-out, runtime extension/migration calls, fleet backlog migration, tier probe extension creation, and a direct-DLL federated integration test. |
-
-No live database, Vault, CI, deployment, issue, PR, or repository mutation was performed. The pass results validate documentation syntax/contract compilation and compose syntax only; they do **not** certify the proposed security behavior.
-
-## Conclusion
-
-Do not merge this frozen contract as implementation-ready until the HIGH findings are corrected and independently re-reviewed. The central role ownership/default-privilege design, immutable-table staging, and KBN-100/KBN-105 serial gating should be retained; they are not the reason for this REQUEST CHANGES verdict.

-2. Implement only a roster-v2 CRUD service and file adapter; no legacy `fleet add/remove` behavior expansion.
-3. Add operator/reference docs for JSON outcomes, generation retries, recovery, and no-runtime-action boundary.
-
-## Progress
-
-- Preflight: clean exact base and no duplicate PR confirmed.
-- Intake read: FCM PRD/AC-FCM-03, task row, launch and generated-env boundaries, roster v2/resolver contracts, legacy fleet command behavior, delivery/QA/TypeScript/security/documentation guidance.
-- TDD: RED observed for the missing CRUD module. GREEN: focused suite passes 7 tests covering stopped-default create, stale generation, idempotency, dry-run non-mutation, concurrent lock denial, exact stale/absent generated-projection delete cleanup, and redacted late-projection recovery.
-- REVIEW-1 remediation: RED observed for absent CLI create/get/update/delete/plan wiring. Added roster-v2-only JSON commands, including safe `get`, read-only planning/dry-run, explicit persisted-start recording (never runtime start), stable handled error codes, and focused CLI coverage.
-- REVIEW-2 remediation: RED observed for missing direct fleet-control-plane registration and ambiguous partial late-I/O result. The public surface is now direct `mosaic fleet {create,get,update,delete,plan}` (not root gateway `mosaic agent`); a late filesystem projection failure returns non-zero redacted JSON with `authoritativeRoster: committed` and `projections: incomplete`, proving no rollback/no-op claim.
-- REVIEW-3 remediation: RED observed for unnamed update/delete plans and deleted-agent quarantine conflict. `plan <operation> [name]` now requires target names only for update/delete; delete validates/removes only exact generated state while retaining local/legacy/quarantine/unrelated files. Actual CLI/filesystem tests cover create/update/delete plans, plan validation/non-mutation, retained artifacts/dry-run bytes, unsafe permission/symlink rejection, and post-roster delete recovery. Added the required operator how-to.
-- REVIEW-4 remediation: RED observed that actual Commander create accepted and silently dropped disallowed `command`, `channel`, and `secretRef` keys. The `--agent` object and nested `launch` now use strict own-property allowlists; non-plain/prototype-sensitive shapes and unknown keys fail `invalid-request` before resolver, roster, or projection mutation. Actual Commander plan/create/update tests cover top-level command/channel/secretRef/constructor/prototype/`__proto__` shapes and nested launch unknown fields, byte-identical retained artifacts, non-zero exit, and diagnostics that never echo rejected values. Docs state the same boundary.
-
-## Risks / assumptions
-
-- **ASSUMPTION:** M2 mutations operate exclusively on the existing v2 roster contract because generation/lifecycle fields are v2-only; legacy v1 add/remove commands remain unchanged compatibility paths.
-- A multi-file roster/projection write cannot be one filesystem rename. The roster is authoritative; a post-roster projection failure returns a redacted recovery plan naming only safe paths/actions, never environment values.

-
-## Objective
-
-Provide local roster-v2 `apply`/`reconcile` and lifecycle/status contracts. The roster remains desired-state authority; projections and runtime observations are derived state.
-
-## Red-first evidence
-
-The initial focused reconciler test failed because `fleet-reconciler.ts` did not exist. The initial new-worktree test invocation also exposed absent dependencies; `pnpm install --frozen-lockfile --store-dir /home/jarvis/.local/share/pnpm/store` restored local workspace dependencies without changing source.
-
-## Design
-
-- A new `fleet-reconciler.ts` accepts only typed roster-v2 input plus injected command and projection adapters.
-- It targets only exact `mosaic-agent@<roster-name>.service` units and the exact configured tmux socket/session.
-- It classifies unowned/unmanaged state and fails mutation closed rather than adopting or killing it.
-- It validates the private install-derived holder identity and complete expected tmux global environment before mutating lifecycle state.
-- REVIEW-1 remediation: RED review evidence found service-level apply could omit generation and had no mutation lock. Every non-observational command now requires an expected generation; a private exclusive roster-adjacent lock is acquired before effects and released on success or partial failure. Tests cover missing/stale values, concurrent denial, no effects, release, and lock-free observation.
-- REVIEW-2 remediation: lock acquisition now validates private real `MOSAIC_HOME`/`fleet` ancestors, rejects symlink or unsafe leaves, distinguishes `EEXIST` concurrency from other I/O, and binds release to the created inode plus random ownership token. A replacement lock is retained and reported, not unlinked. A crash may leave a stale lock for inspection; no stale-lock break is claimed.
-- REVIEW-3 remediation: a lock cleanup failure now adds bounded `cleanup` diagnostics to a known successful or partial effect result without replacing its projection/lifecycle/recovery truth. Cleanup is not claimed as complete, and the retained lock requires inspection before retry.
-- REVIEW-4 remediation: command JSON with an additive cleanup diagnostic now exits non-zero even where known effects completed; clean effect and observational JSON remain zero-exit.
-- REVIEW-5 remediation: mutating operations acquire the private lock before rereading canonical `roster.yaml`; the fenced reread, not a caller snapshot, supplies generation validation, plan, projection, and lifecycle authority.
-- `apply` starts only enabled agents whose persisted desired state is `running`; stopped/default agents are never started by reconciliation.
-- Observational commands produce JSON classification only. Partial projection or lifecycle effects report explicit recovery without values.
-
-## Boundaries
-
-Excluded: live host actions, remote/SSH/connector lifecycle mutation, migrations, canaries, deployment, gateway changes, arbitrary command/channel/secret inputs, `docs/TASKS.md`, and orchestration ledgers.

-## Verification
-
-- Focused reconciler/Commander/CRUD/fleet tests: 4 files / 229 tests passed.
-- Full `@mosaicstack/mosaic` suite: 56 files / 820 tests passed after REVIEW-5 canonical roster fencing remediation.

-## Objective
-
-Add broad, behavior-oriented acceptance evidence around the shipped local reconciler contracts. Exercise only injected fake systemd/tmux adapters and temporary filesystem fixtures. Prove exact ownership/targeting, persisted stopped-state safety, truthful partial-failure recovery, rollback behavior, and stable command JSON/exit outcomes without touching live services or sessions.
-
-## Acceptance mapping and evidence
-
-| FCM-M3-002 acceptance concern | Delivered isolated evidence |
-| --- | --- |
-| Systemd/tmux lifecycle | `fleet-reconciler.acceptance.spec.ts` drives apply, reconcile, stop, restart, status, and recovery reconcile through one stateful injected fake host. The fake models exact systemd effects and tmux session observations; no host commands run. |
-| Drift | Canonical roster-v2 YAML drives the Commander `fleet status` boundary and classifies `missing-session`, `unexpected-session`, and `disabled-running`, including combined drift, while asserting observation emits no lifecycle mutation. |
-| Exact default/named socket targeting | Canonical v2 requires an explicit non-empty named socket; the parser rejects missing/empty values and the Commander acceptance path asserts exact `-L mosaic-fleet` targeting. A separate canonical legacy-v1 roster loader plus runtime-transport path proves a socket-less compatibility roster targets the literal tmux default server with no `-L`. No unreachable empty-socket v2 fixture is used. |
-| Unmanaged-session classification | Stateful fixtures report sorted `coder0-shadow`/`unmanaged` sessions, then prove an exact roster stop leaves both sessions and the near-collision service intact. |
-| Crash/partial failure | Injected restart failure is applied after the fake effect to model crash/partial truth: result is `lifecycle: incomplete`, the roster is unchanged, and observed runtime may be active. |
-| Rollback/recovery semantics | M3 has no rollback command and explicitly does not claim automatic rollback. The acceptance workflow proves the bounded recovery contract: inspect, then exact reconcile restores the persisted stopped target without a start or fuzzy effect. M4 migration/canary rollback remains outside this card. |
-| Stopped-state preservation | Stateful apply and reconcile both stop an initially running observed agent whose persisted target is stopped; failed explicit restart leaves desired state stopped; recovery reconcile restores stopped state. No start call is emitted. |
-| Zero fuzzy destructive targeting | Near-collision `coder0-shadow` service/session plus `unmanaged` session remain untouched. The recorded destructive calls contain only exact `mosaic-agent@coder0.service`; no tmux kill action is emitted. |
-| Stable JSON/exit behavior | Temporary canonical roster fixture invokes the CLI boundary and asserts exactly one JSON line, exact partial-result shape, and exit code 1. Existing focused command specs continue to cover clean zero-exit and stable error JSON. |
-| Redacted truthful recovery | Fake stderr includes `PASSWORD=acceptance-secret`; exact CLI JSON contains only bounded recovery metadata and excludes the key, value, and raw diagnostic. |
-
-## Plan
-
-1. Inventory existing reconciler and command specs against the table above; avoid duplicating narrow assertions already present.
-2. Add one acceptance-level spec using only fake/injected adapters and temporary files.
-3. If a real defect is exposed, preserve the failing reproducer and make only the smallest FCM-M3-002-required fix; otherwise leave production unchanged.
-4. Reconcile `docs/TASKS.md` only for delivered M1/M2/M3-001 truth and mark FCM-M3-002 in progress.
-5. Run focused tests, full `@mosaicstack/mosaic` tests, package/root typecheck and lint, Prettier/format and diff checks, plus adversarial fake-runner cases.
-6. Record exact evidence and leave the tree uncommitted for independent synthetic-tree review.
-
-## TDD decision
-
-This card adds acceptance coverage to already-delivered behavior. Test-first applies to any product defect discovered: retain a failing reproducer before an in-scope fix. If the shipped behavior already satisfies the acceptance contract, no production code will be changed and the acceptance suite itself is the deliverable.
-
-## Progress
-
-- Intake and immutable baseline verification complete.
-- Existing coverage inventory confirmed strong unit coverage but no stateful cross-command lifecycle acceptance harness.
-- Added `packages/mosaic/src/fleet/fleet-reconciler.acceptance.spec.ts`: one injected stateful fake systemd/tmux host, temporary canonical v2 and legacy-v1 roster fixtures, and seven acceptance tests.
-- Production source is unchanged; no product defect requiring an FCM-M3-002 fix was found.
-- `docs/TASKS.md` reconciles only merged M1/M2/M3-001 truth and marks FCM-M3-002 in progress.
-
-## Verification evidence
-
-All commands ran from `/home/jarvis/src/mosaic-stack-local-reconciler` and passed unless explicitly noted.
-
-- `pnpm --filter @mosaicstack/mosaic exec vitest run src/fleet/fleet-reconciler.acceptance.spec.ts` — final remediation run: 1 file, 7 tests passed; canonical v2 named-socket parsing/Commander status, missing/empty v2 rejection, and canonical legacy-v1 default-server runtime targeting are distinct reachable cases.
-- Focused reconciler/roster/transport command covering acceptance, reconciler, command, CRUD, v2 parser, and runtime transport specs — 8 files, 304 tests passed.
-- `pnpm --filter @mosaicstack/mosaic test` — final remediation run: 57 files, 827 tests passed.
-- `pnpm --filter @mosaicstack/mosaic typecheck` — passed.
-- `pnpm --filter @mosaicstack/mosaic lint` — passed.
-- `pnpm typecheck` — 42/42 Turbo tasks successful.
-- `pnpm lint` — 23/23 Turbo tasks successful.
-- `pnpm exec prettier --check docs/TASKS.md docs/scratchpads/758-fcm-m3-002-reconciler-lifecycle-gates.md packages/mosaic/src/fleet/fleet-reconciler.acceptance.spec.ts` — passed.
-- `pnpm format:check` — all matched files use Prettier style.
-- `git diff --check` — passed with no output.
-- Initial scoped Prettier check found style drift in the new spec and tracking table; `pnpm exec prettier --write ...` remediated it before all final gates above.
-- No live fleet, systemctl, tmux, process, site, migration, canary, deploy, runtime, connector, or remote command was invoked.
-
-## Review boundary
-
-This is an author handoff. No self-review is represented as reviewer-of-record. The uncommitted synthetic tree is intended for independent review.
-
-## Risks / blockers
-
-- M3 truthfully reports incomplete lifecycle effects and bounded recovery; it does not implement or claim an automatic rollback command. This suite proves stopped-state restoration by the documented exact recovery reconcile. M4 retains migration/canary rollback ownership.
-- The fake host models only the public systemd/tmux runner contract and temporary roster filesystem boundary. This is intentional under the no-live-effects hold.
-- Parent issue closure, commit, push, PR, merge, deployment, and branch cleanup remain explicit holds.
-- No residual implementation blocker.

-# FCM-M4-001 — v1-to-v2 inventory, preview, and migrator
-
-- **Task / issue:** FCM-M4-001 / mosaicstack/stack#758
-- **Branch / base:** `feat/758-v1-v2-migrator` from `origin/main` `c1aecfabe97a5dc81a72f44910cd4e626f41863f`
-- **Base tree:** `46cdfbcdc1d1ff9c7b8b2b9cf3841086590bf774`
-- **Scope:** field-complete inventory, non-mutating preview, canonical v2 migration output, and migration/recovery disposition evidence. All effects use injected fakes or temporary fixtures.
-- **Budget:** 35K task estimate is the hard working cap. Keep one card/one PR and prefer focused reuse of the v2 compiler, shared role resolver, generated-env boundary, M1 executable disposition inventory, and reconciler observations.
-
-## Objective
-
-Implement preview-first v1 migration that never infers unresolved classes or lifecycle, preserves observed running/stopped state, quarantines forbidden legacy environment inputs with key-name/SHA-256-only diagnostics, inventories remote/connector/schema-only entries without reconciling them, covers every M1-classified shipped artifact, and emits deterministic recovery disposition evidence for the later M4-002 canary/rollback gate.
-
-## Acceptance mapping
-
-1. Field-by-field v1 inventory and no-mutation preview.
-2. Canonical output compiled by `roster-v2.ts` and semantically validated by the existing baseline-plus-`roles.local` resolver.
-3. Only approved deterministic aliases; every other noncanonical class requires an explicit disposition.
-4. Observed stopped/running maps explicitly to persisted lifecycle; stopped observations never produce running targets.
-5. Generated env is regenerated; strict local data is relocated; forbidden keys are quarantine inputs reported only by key name and SHA-256.
-6. Remote/connector/schema-only entries are inventory-only and excluded from local reconciliation output.
-7. Every shipped M1 example/profile/service preset has executable migration disposition evidence.
-8. Deterministic migration/recovery evidence records source, output, exclusions, quarantine, and restore prerequisites without executing a canary or rollback.
-
-## Boundaries
-
-Out of scope: FCM-M4-002 executable canary/rollback and host fixture, #766 communications, #636 commands/channels, live fleet/systemd/tmux/session/migration/deploy/connector/remote/gateway effects, `docs/TASKS.md`, parent issue mutation, commit, push, and PR operations.
-
-## TDD plan
-
-Migration rules and redaction are critical data-mutation/security logic, so tests are written red-first for inventory completeness, explicit class disposition, observed-state preservation, quarantine redaction, inventory-only remote/schema entries, compiler/resolver reuse, artifact coverage, and recovery evidence. Production code follows only after the focused tests fail for the missing behavior.
-
-## Plan
-
-1. Map existing v1 loader, v2 compiler/resolver, env quarantine, reconciler observation, and M1 disposition guard.
-2. Add behavior-oriented failing migration tests with temporary fixtures and injected observation/filesystem adapters only.
-3. Implement the narrow migration module and CLI boundary without a second resolver or live command runner.
-4. Add scoped M4 migration/recovery documentation and executable shipped-artifact evidence.
-5. Run focused tests, full package tests, package/root typecheck and lint, formatting, diff checks, and adversarial redaction/no-effect verification.
-6. Run independent code/security review, remediate findings, reconstruct the synthetic tree using a temporary index, and stop uncommitted.
-
-## Progress
-
-- Collision checks passed: no local/remote branch, worktree, target path, or open PR owned `feat/758-v1-v2-migrator`.
-- Dedicated worktree created at the exact green `origin/main` base.
-- Required global/repository guides and FCM requirements/evidence loaded.
-- No matching migration skill exists under the configured skill directories; no unrelated skill loaded.
-- Added a preview-only CLI and migration module that compile with the existing v2 parser/renderer and validate through the shared persona resolver.
-- Added value-free raw-v1 inventory, strict unknown-field/synonym/duplicate detection, inventory-only remote and connector handling, and explicit class/tool-policy decisions.
-- Added separate reviewed lifecycle observations with only unambiguous running/stopped mappings.
-- Added sanitized, non-mutating environment preflight and recovery evidence explicitly marked non-executable.
-- Added executable disposition evidence derived from the exact 13-entry M1 inventory and operator documentation.
-- Tightened untrusted decisions/observations to reject unknown keys, invalid types/enums, extra local records, and competing automatic-alias dispositions.
-- Remediated independent review findings: v1 runtime/reset defaults are preserved, `~` workdirs expand only at env preflight, malformed/required agent fields fail closed before remote exclusion, and all seven shipped v1 fixtures now execute real previews with explicit evidence.
-- Remediated socket and locality authority blockers: socket-only agents stay local; `host == fleetHost` stays local; only `host != fleetHost` is inventory-only; ssh-only, missing reviewed fleet-host identity, and contradictory host/ssh targets block explicitly without lifecycle omission.
-- Remediated final exact-tree blockers: a declared v1 root socket cannot be overridden; matching/conflicting socket decisions retain reviewed running evidence; canonical ordering uses a shared locale-independent Unicode code-point comparator; migration evidence preserves all four legacy environment dispositions; backup documentation no longer claims validation that M4-001 does not perform.
-- Remediated immutable-review socket-presence blocker: both `socket_name` and `socketName` are field-presence-aware, so explicit empty/default-server declarations remain authoritative and incompatible named decisions block rather than replacing them.
-- Remediated the replacement-tree blockers: the shared v2 compiler and reconciler accept an explicit empty socket as literal default-server identity; present-empty holder session, default/agent work directory, runtime reset command, and alias values block rather than defaulting; missing preview inputs emit one stable blocked JSON object with non-zero status. Snake/camel aliases and whitespace-only input have adversarial coverage.
-- Remediated the subsequent authority blockers: each present-empty CLI path emits exactly one stable blocked JSON object with exit 1 before file reads, and reconciler `start`/`restart` or desired-state `apply`/`reconcile` fail closed before fixed `mosaic-fleet` systemd services can act on a default-server roster.
-- Remediated committed-head review blockers: explicitly declared empty runtime objects use the production v1 `/clear` reset fallback while omitted `pi` retains `/new`; lifecycle observations are sorted by canonical agent name; and bare CLI path flags reach preview validation, emit one stable blocked JSON object with exit 1, and perform zero reads. Built production-CLI subprocess tests cover all three bare flags.
-- Remediated late-audit blockers: the documented M4 guard invokes the 13-artifact validator and all seven v1 previews; canonical `~`/`~/...` workdirs remain unchanged in migration evidence and traversal-free forms expand at the shared production projection boundary while ordinary relative and home-relative traversal paths remain rejected; remote inventory and exclusion evidence sort canonically; and every default-server lifecycle-mutating reconciler path fails before observation, projection preparation/application, or fixed-unit effects. Explicit regressions preserve `plan`, `status`, `doctor`, and `verify` as observational default-server commands.
-- Remediated exact-tree traversal review: `~/../escape` and `~/src/../../escape` remain unexpanded and fail the unchanged shared `unsafe-path` validation. Both the shared generated-environment boundary and the production v1 environment caller have red-first regressions, preventing earlier caller normalization from bypassing the boundary.
-
-## Verification evidence
-
-- Focused migration/compiler/environment/reconciler/CLI: 8 files, 372 tests passed.
-- Documented 13-artifact guard: 1 matching test passed and executed all seven v1 previews.
-- Full `@mosaicstack/mosaic`: 59 files, 902 tests passed.
-- Workspace build: 23 tasks passed.
-- Root typecheck: 42 tasks passed.
-- Root lint: 23 tasks passed.
-- Root format check and `git diff --check`: passed.
-- Built production CLI: canonical `~/src` remains in ready roster/YAML evidence; generated projection preflight succeeds with no blockers; a bare path flag emits one blocked JSON object, exit 1, and no stderr.
-- Independent high-effort late-audit review: no blocker remained in the four assigned repair surfaces; separate exact-tree security audits found no qualifying newly introduced vulnerability.
-- Exact temporary-index synthetic tree includes every tracked changed path; immutable SHA and duplicate reconstruction are recorded in the final handoff.
-
-## Risks / blockers
-
-- M4-001 emits rollback prerequisites/evidence only; executable rollback/canary and the managed/unmanaged host fixture remain owned by M4-002.
-- Remote/connector entries remain inventory-only; later federation or connector reconciliation requires separately reviewed work.
-- Existing environment data is only preflighted. Cutover backup, quarantine write, legacy removal, and generated projection application remain later reviewed effects.

-# Scratchpad — KBN-101 DB runtime/migration role split (#771)
-
-- **Branch:** `docs/771-kbn101-db-role-split`
-- **Base:** `main` `e9c4aa3`
-- **Scope:** planning/documentation only; authorized files are PRD, Native Kanban task/shared/index docs, sitemap, this scratchpad, and the new KBN-101 contract.
-- **Explicit exclusions:** source/runtime/config/deployment/secret/migration/compose/CI/lock/package/KBN-100 branch edits; no production mutation.
-
-## Objective
-
-Freeze an implementation-ready PostgreSQL role/connection split so the Gateway uses a non-owner runtime identity and only a dedicated migration phase uses an owner/migrator identity. Make real deployed-role certification—not synthetic role tests—a serial prerequisite of KBN-100 and KBN-105.
-
-## Intake and current-state evidence
-
-- Mission MVP is active; W3 Native Kanban/SOT is planning-complete. The task state shows KBN-010 as the predecessor and KBN-100 as the current schema slice.
-- Current branch started at `e9c4aa3`; `.mosaic/orchestrator/{mission.json,session.lock}` were already runtime-modified and remain untouched.
-- `packages/db/src/client.ts`, `migrate.ts`, and `drizzle.config.ts` resolve one `DATABASE_URL` (with default fallback). `packages/storage/src/adapters/postgres.ts` calls `runMigrations(this.url)`.
-- `apps/gateway/src/database/database.module.ts` calls `storageAdapter.migrate()` at startup for PostgreSQL; this is the owner-runtime defect to remove in KBN-101 implementation.
-- `packages/config/src/mosaic-config.ts`, installer wizard, local/federated compose, Portainer test stack, and `.woodpecker/ci.yml` currently expose one URL. PGlite has an existing explicit local migration path.
-- Current KBN contract requires immutable events/checkpoints/artifacts/evidence, `RESTRICT`, and KBN-100 generated Drizzle consistency. It did not establish a deployable runtime identity split.
-
-## Frozen decisions
-
-1. `DATABASE_URL` is the non-owner runtime URL; `DATABASE_MIGRATION_URL` is migration-only. Both are required in their respective PostgreSQL phases; PGlite is the explicit local exception; migration never falls back to runtime/default/config URL.
-2. PostgreSQL Gateway runtime never auto-runs migration/DDL. Dedicated migrator uses `pg_try_advisory_lock(hashtext('mosaic-schema-migration-v1'))`; replicas only check exact ordered Drizzle-ledger readiness and fail closed.
-3. Roles are non-login `mosaic_platform_database_owner`, non-login `mosaic_schema_owner`, login/noinherit `mosaic_migrator`, non-login `mosaic_runtime_capability`, and login/inherit `mosaic_runtime`. Runtime inherits only its capability role with SET/ADMIN denied, has no owner/migrator membership, no unsafe attributes/ownership/DDL authority, and an explicit trusted search path.
-4. Runtime gets mutable DML only as needed, but INSERT/SELECT only on `task_events`, `artifacts`, `task_checkpoints`, `task_checkpoint_artifacts`, and `approval_decision_artifacts`. KBN-100 still enforces RESTRICT/no-cascade.
-5. Startup verifies effective role/ownership/attributes/inherited capability/TEMP/function-execute/ledger grants/search path/immutable denials/schema fingerprint without DSN exposure. It also requires authenticated CA/hostname-verified TLS. Stable sanitized errors and redaction rules are required.
-6. N-1 retains single runtime URL only as a non-certified compatibility release; staged role provisioning/migration/runtime deployment then enforces the split. Rollback never injects migration URL into Gateway.
-7. Vault target paths, rotation, deployment injection, CI, installer, compose, Portainer, and observability are separate one-card/one-PR handoffs. The migration-only file manifest includes `packages/db/drizzle.config.ts`; KBN-101 repairs the known PostgreSQL runner/journal ordering defect and proves a clean database applies every hash once before its foundation certificate. No application migration creates roles/passwords or hardcodes credentials.
-8. KBN-101 foundation merges/certifies first. KBN-100 then rebases, restores Drizzle declaration/snapshot/journal consistency, and bounds procedural immutable-table grant/trigger/backfill work to its own slice. Because those immutable relations do not exist until KBN-100, KBN-101’s real deployed-role immutable-operation certificate follows KBN-100 and is the serial gate before KBN-105.
-
-## Assumptions
-
-- `standalone` and `federated` are all current PostgreSQL production-like modes; a future PostgreSQL tier inherits this contract unless versioned otherwise.
-- Deployment will support a dedicated migration Job/one-shot command. A target that cannot run it cannot receive production/federated KBN certification.
-- Canonical Vault target paths require deployment-owner verification before provisioning; the planning document does not claim they already exist.
-
-## Documentation produced
-
-- `docs/PRD.md`: bounded KBN-101 requirements and acceptance criteria.
-- `docs/native-kanban-sot/KBN-101-DB-ROLE-SPLIT.md`: normative rc.5 implementation, threat, migration/rollback, evidence, and exact file DAG contract.
-- `docs/native-kanban-sot/SHARED-CONTRACT.md`: rc.5 amendment preserving rc.4.
-- `docs/native-kanban-sot/TASKS.md`: KBN-101 inserted before and blocks KBN-100; KBN-105 held.
-- Native Kanban index and root sitemap links.
-
-## Validation plan
-
-1. Prettier only for changed Markdown.
-2. Markdown link target/check checks scoped to modified docs.
-3. Strict contract check with `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json` (the frozen TypeScript contracts remain unchanged).
-4. Diff allowlist proves only authorized documentation files changed, apart from pre-existing Mosaic runtime state.
-5. Independent documentation/security self-review: role escalation, fallback, startup DDL, schema readiness, grants/default privileges, immutable tables, secret leakage, deployment and KBN-100 boundaries.
-
-## Review corrections
-
-Independent Codex review found two blockers and security review found two medium defects; all were remediated in the frozen contract:
-
-1. Split the KBN-101 certificate into a foundation role/schema-boundary certificate (before KBN-100) and real immutable-operation certificate (after KBN-100, before KBN-105). This preserves the requested KBN-100 block without requiring evidence for tables not yet created.
-2. Removed the legacy owner-runtime exception. N-1 compatibility preserves variable/config shape only; the KBN-101 runtime refuses owner/migrator identity and current single-URL installs remain on their previous release until role cutover.
-3. Introduced `mosaic_platform_database_owner` as a separate non-login platform role. `mosaic_schema_owner` owns application/ledger schemas only, not the database and has no database CREATE/ALTER/extension authority.
-4. Replaced blocking `pg_advisory_lock` with `pg_try_advisory_lock` and the deterministic `DATABASE_MIGRATION_LOCKED` failure.
-5. Review also flagged active `.mosaic/orchestrator` state. It was pre-existing launcher state and remains unstaged/uncommitted.
-6. Second review added `packages/db/drizzle.config.ts` to the migration-only slice, mandates `DATABASE_MIGRATION_URL` with a missing-variable negative, grants runtime only `USAGE` plus `SELECT` on `drizzle.__drizzle_migrations`, and verifies/revokes its ledger writes.
-7. Security review added `DATABASE_TLS_CA_CERT_PATH` / `DatabaseTlsConfigDto` with authenticated TLS and hostname/CA verification in production-like modes, explicit database `TEMPORARY` revocation/catalog denial testing, and default-PUBLIC function EXECUTE revocation with SECURITY DEFINER prohibited by default.
-8. Final review corrected the runtime login to inherit only its capability role with SET/ADMIN denied, and moved the known hash-complete migration-runner/journal repair into KBN-101-03 before the foundation certificate.
-9. Final manifest review added all live runtime DDL paths (`packages/storage/src/tier-detection.ts`, Gateway startup, and `fleet-backlog`) to KBN-101-02, requiring read-only extension probes and no PostgreSQL runtime auto-migration. It also requires KBN-101-04 to stop persisting either DSN into generated `.env`/`mosaic.config.json`, using only Vault/deployment references and injected variables.
-10. Provisioning review separated the external privileged platform bootstrap actor from the NOCREATEDB database-owner role and added KBN-101-00. That IaC/bootstrap card owns fresh/existing database role/ownership/grant/Vault transition evidence and is a foundation-certificate dependency.

-## Results
-
-- `pnpm exec prettier --check` on every authorized Markdown file: PASS.
-- Markdown link and whitespace checker on all seven authorized Markdown files: PASS.
-- `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json`: PASS (frozen strict contracts unchanged).
-- Codex code review iterated through role inheritability, hash-complete migration ordering, all reachable runtime DDL entrypoints, installer DSN persistence, and platform-bootstrap ownership; each finding was incorporated into the final frozen contract/DAG. The last security review found no new KBN-101 vulnerability; its sole low finding is the pre-existing unstaged Mosaic session-lock metadata, which is excluded from this commit.
-- Commit: `82ce3252df38a687c50485f8d048b53ca8db5989` (`docs(#771): freeze database runtime role split`).
-- Pre-push queue guard: `ci-queue-wait.sh --purpose push -B main` returned `state=unknown` without failure. The push hook ran repository `pnpm typecheck`, `pnpm lint`, and `pnpm format:check`: PASS.
-- Pushed branch `docs/771-kbn101-db-role-split` at the exact commit above; no PR was opened, merged, or closed. `web1:mosaic-100` received the handoff with head, decisions, DAG, and validation.
-- Awaiting independent security/Ultron review.
-
-## 2026-07-15 — rc.6 exact-head remediation session
-
-- **Objective / correction:** Replace the prior planning-author handoff and close every finding in the [independent exact-head report](../reports/native-kanban-sot/kbn-101-contract-security-review-82ce325.md) against `da742ca2da4a2ff466916c818fe275c4f7ffd384`. The report is a verbatim durable copy of the task-supplied review artifact; scope remains documentation-only, `.mosaic` is excluded, and source/config/compose/CI/deployment/secrets/migrations remain untouched.
-- **Finding 1 — closed DDL control plane:** rc.6 names `mosaic-db-migrator` as the sole application/CI/test PostgreSQL DDL runner, requires `DATABASE_MIGRATION_URL` before connection/DDL, inventories `runMigrations`, Drizzle config/scripts, `db:push`, storage CLI, adapter/Gateway startup, fleet-backlog, extension probes/bootstrap, direct federated integration DDL, CI, and future scripts, and specifies route/deny/test disposition for each. Tests use runner-prepared disposable PostgreSQL or invoke that runner; `db:push` is local-disposable-only and rejects production-like URLs.
-- **Finding 2 — deployable TLS:** rc.6 freezes distinct runtime/migrator URL and CA/server leaf Vault/compose/Swarm secret identifiers, `0400` key and `0600` URL/cert/CA mount requirements, actual compose/Swarm service-DNS SANs, PostgreSQL TLS settings, legacy-client drain/termination plus `hostssl` enforcement, verified-TLS readiness ordering, fresh/existing transition, CA-overlap rotation/TLS-only rollback, and standalone plus federated/Swarm positive and missing/wrong CA/SAN/downgrade negatives. PGlite is explicitly non-PostgreSQL evidence.
-- **Finding 3 — manifest/0009:** rc.6 defines manifest v1 canonical UTF-8 serialization and raw SQL-byte SHA-256, logical journal order, manifest ownership/grants, exact one-to-one observed hash tuple mapping, non-normative physical insertion order, safe original-0009 conditions, ambiguous-effect fail-closed recovery, and the full required reconciliation/backup test matrix. It preserves shipped 0009 bytes and forbids manual ledger adoption/insertion.
-- **Finding 4 — advisory lock:** replaced `hashtext` with fixed signed-int4-safe `(1297044289,1262636593)` (`MOSA`,`KBN1`), one `max:1` runner session, close-on-crash semantics, and contention/crash/readiness/unrelated-key evidence.
-- **Finding 5 — identifiers/search path:** selects `mosaic`, exact `pg_catalog,mosaic` per pooled connection and `SET LOCAL` transactions, plans audited public-object/extension/Drizzle relocation, forbids config-derived identifiers, limits bootstrap quoting to server-side `%I` on fixed allowlist, and requires injection/pool-reset negatives.
-- **Finding 6 — safe DAG:** cards 00–07 are inactive prepared capability while owner-runtime remains N-1; KBN-101-08 is the one atomic activation release after platform roles/TLS and compatible code. Mosaic control plane/Jason alone can activate/rollback; no force-on-red, runtime bypass, or temporary compatibility survives the gate. The approved role graph, post-KBN-100 immutable certification, and KBN-105 gate remain unchanged.
-- **Review remediation:** Codex review found the legacy plaintext cutover gap, missing URL-secret bindings, historical `public` migration incompatibility, non-reproducible checkout-byte hashing, CONNECT allowlisting regression, and undocumented direct-DDL operator instructions. rc.6 now requires drain/scale-to-zero, residual non-TLS session termination, `hostssl` with no `host` rule, zero plaintext-session proof, TLS-only post-enforcement rollback, distinct named runtime/migrator secret consumers, canonical Git-blob/LF manifest bytes, a runner-only owner-controlled legacy-public bootstrap followed by `mosaic` relocation, explicit CONNECT/TEMP revocation, and KBN-101-07 replacement of direct-DDL documentation. It also required the durable exact-head report link above. Pre-existing `.mosaic` runtime state remains excluded.
-- **Validation:** Prettier on all changed Markdown, repository Markdown link/whitespace check, and strict native-kanban contract TypeScript passed before final staging; the final staged diff excludes `.mosaic`. No source-code TDD applies because this is contract-only remediation.
-
-## 2026-07-15 — rc.7 residual remediation session
-
-- **Objective / correction:** Close every residual in the independent exact-head rc.6 re-review at `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview-45ba3d6.md` for `45ba3d6ad4d5383f457a303c05bc816144cfa48a`, without changing source, compose, CI, deployment, migration, or secret artifacts. Only the existing authorized planning/documentation paths are eligible; pre-existing `.mosaic` state remains excluded.
-- **Source-backed scope confirmed:** the active `federated-pgvector.integration.test.ts` executes `CREATE TEMP TABLE`; tracked `docker/init-db.sql` and `infra/pg-init/01-extensions.sql` both create `vector`; `migrate-tier.ts` advertises raw `CREATE EXTENSION`; and `tools/federation-harness/docker-compose.two-gateways.yml` is current plaintext two-PostgreSQL/two-Gateway topology. Current `schema.ts` has 36 default-schema `pgTable` declarations, 6 default `pgEnum` declarations, and an unqualified `vector` custom type; historical migrations contain `public` references.
-- **Plan:** (1) make the finite DDL/static-bypass inventory and `DATABASE_URL`-only denial matrix exact, including the runner-prepared persistent pgvector fixture and migrated two-gateway harness; (2) freeze executable `public`-to-`mosaic` and `mosaic_extensions` transition, Drizzle ownership, object-catalog classes/order, eligibility and rollback tests; (3) bind repository/control-plane ownership, UID/GID validation, exact artifact/mount rules, and both gateway TLS topology; (4) correct PRD acceptance mapping and cross-document rc.7 status; then run formatting, link/contract, source-path, diff, review, commit, queue guard, and push.
-- **Independent review closure:** initial Codex review found Gateway-key consumer wording, `CLAUDE.md` omission, final schema-owner set, and placeholder SANs; all are now explicit. Re-review found the legacy `0001` vector-type resolution problem and `docs/federation/SETUP.md` raw-DDL instruction; the legacy runner now uses only its fixed non-writable `pg_catalog,public,mosaic_extensions` history path, while runtime remains `pg_catalog,mosaic`, and the federation setup path is assigned to KBN-101-07/static inventory. Security review final verdict: no confident vulnerability. The review also repeated the pre-existing tracked `.mosaic` session-state concern; it remains deliberately unstaged/excluded by this task.
-- **Completion evidence:** changed Markdown is Prettier-formatted; local links and strict native-kanban TypeScript passed; source-path inventory confirmed all current referenced paths (the new `apps/gateway/Dockerfile` is explicitly a planned KBN-101-05 artifact); diff check and authorized-doc allowlist passed. No source-code TDD applies to this documentation-only remediation.
-
-## 2026-07-15 — rc.8 exact residual remediation session
-
-- **Objective / correction:** Close all three HIGH findings in the independent rc.7 exact-head re-review at `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview2-0778eba.md` for `0778eba2db3c2dfbaca3af352b12ba0389d3552b`. Scope remains documentation-only: no source, config, Compose, CI, deployment, secret, or migration artifact changed; pre-existing `.mosaic/orchestrator` state remains excluded.
-- **Finite authority closure:** KBN-101-06 now classifies exact current source/scripts/package bins, operator docs, and deploy manifests. `packages/db/src/index.ts` has explicit removal/compile-import negative ownership; `docs/fleet/backlog-conventions.md` and `docs/PERFORMANCE.md` now remove first-use/direct-Drizzle/Gateway-startup migration instructions and point to sole runner/readiness. Byte-immutable historical SQL, PGlite-only routines, negative-test literals, vendored/generated artifacts, and labeled historical reports are exact-path/category reviewed allowlists; unknown hits fail. The contract explicitly rejects relying on a naive token scan alone.
-- **Executable and exclusive handoff closure:** KBN-101-03 exclusively owns the published `mosaic-db-migrator` bin, `packages/db/src/cli.ts`, private migrator modules, `docker/db-migrator.Dockerfile`, exact `--run|--verify|--help`, environment/argv limits, sanitized exits, and command/order tests. KBN-101-00 exclusively owns `infra/pg-bootstrap/roles.sql`, `infra/pg-bootstrap/extensions.sql`, `infra/pg-bootstrap/README.md`, and bootstrap tests. KBN-101-05 exclusively owns `tools/db/render-postgres-secrets.ts`, its tests, and deployment declarations, consuming the versioned bootstrap interface without overlap.
-- **pgvector owner closure:** `mosaic_extension_owner` is dedicated NOLOGIN, available only to the external bootstrap actor during bootstrap; fresh vector/member ownership remains there. The contract records PostgreSQL's unsupported extension-owner transfer and forbids catalog mutation, ownership adoption, and `DROP CASCADE`. Approved-owner existing extensions use verified `ALTER EXTENSION ... SET SCHEMA`; legacy runtime-owned extensions fail closed to a controlled backup/shadow/runner/copy-evidence/quiesce/final-delta/atomic-switch/read-only-rollback migration. It requires `pg_extension.extowner`, member/schema/version, and runtime/migrator/schema-owner ALTER/DROP/member-update denial tests across clean, approved-owner, legacy shadow, partial/resume/rollback, and N-1.
-- **Cross-document state:** PRD, KBN contract, shared contract, task decomposition, index, sitemap, current operator docs, and this scratchpad are rc.8-consistent. The only intended next action is a fresh independent exact-head re-review after validation/push.
-- **Validation / review:** Prettier passed for all nine changed Markdown documents; local links passed (9 documents); `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json` passed; source-path inventory passed (20 paths: 8 current, 12 explicitly planned); finite-authority requirement checklist and `git diff --check` passed. Manual documentation/security review checked the three requested paths, private-only runner boundary/exit contract, non-overlapping 00/03/05 ownership, extension-owner denial and shadow path, and `.mosaic` exclusion. No source-code TDD applies because this is contract-only remediation.
-- **Delivery evidence:** committed `1423c2ad02b5471eab006fb4c878808e5b29c387` as `docs(#771): close role split rc.8 residuals`. Push queue guard returned `state=unknown` without error; push hook ran repository `pnpm typecheck`, `pnpm lint`, and `pnpm format:check`, all PASS; branch push succeeded. This final evidence append is committed next, then the exact remote head is verified. The only intended next action is a fresh independent exact-head re-review.

-## 2026-07-15 — rc.9 final residual remediation session
-
-- **Objective / correction:** Close the three findings in `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview3-9cf5d2f.md` against exact head `9cf5d2f6641b14082dc3294e2a84d1fb4ccc019d`: move `mosaic_extensions` schema ownership to `mosaic_extension_owner`; replace all broad/conflicting KBN-101 card ownership with a complete disjoint exact-path/test manifest; and classify the current architecture-plan `db:migrate` instruction with pinned scanner mechanics. Scope remains documentation-only; no source/config/Compose/CI/deployment/secret/migration artifact and no `.mosaic` path may be modified.
-- **Plan:** inspect current tracked source topology to name only existing paths; update the normative contract first and synchronize PRD/shared/task/index/sitemap/version language; run Prettier, changed-doc links, strict contract TypeScript, source/path and manifest-overlap checks, diff allowlist, independent documentation/security review; then stage docs only, commit, queue-guard, push, and verify exact remote SHA. No source-code TDD applies because this is contract-only remediation.
-- **Closure implemented:** rc.9 makes `mosaic_extension_owner` create and own `mosaic_extensions`, `vector`, and members; the external bootstrap actor alone temporarily `SET ROLE`s for fresh/approved-owner work, while schema owner has only `USAGE` for legacy type resolution and never temporary `CREATE`. Catalog/default-ACL plus direct DDL/member denials now cover runtime, migrator, and schema owner through fresh, relocation, shadow/resume, and rollback evidence.
-- **Delivery decomposition:** Replaced broad ownership with complete disjoint 00–09 manifests, exact tests/evidence, producer-before-consumer edges, and an explicit no-intermediate-deploy N-1 activation statement. `packages/storage/src/{cli,migrate-tier}.ts` belongs only to -02; the current tracked init artifacts are retired by -02 as direct-DLL closure; -03 owns all runner/index/migrate/config/schema assets and exact compiled-bin/image mapping; -07 owns docs only; -08/-09 own evidence only.
-- **Classifier closure:** -06 has exact scanner/inventory/matrix paths, canonical inventory fields, classes/dispositions, fixed token/rule set, exact allowlist categories/restrictions, and self-test requirements for unknown, duplicate-owner, ownerless, missing-path, and historical masking cases. The architecture plan now marks direct `db:migrate` superseded and uses `mosaic-db-migrator --run`.
-- **Validation:** Prettier check, strict native-kanban contract TypeScript, changed-document local-link resolution, `git diff --check`, and an automated manifest-overlap/owner/current-source-path check passed. Targeted documentation/security review verified role ownership/default privileges/search path/preflight/legacy/shadow/rollback consistency, disjoint manifests/DAG/activation, scanner mechanics, exact bin/entrypoint, and no `.mosaic` staging intent. No source-code TDD applies because this is documentation-only remediation.
-- **Next:** stage documentation only, commit, queue-guard, push, verify exact remote SHA, then wait for fresh exact-head review.
-- **Delivery evidence:** committed `8cbad2bcd9bc7507052f74f35670ef7c8e39e44e` as `docs(#771): close role split rc.9 residuals`; `ci-queue-wait.sh --purpose push -B main` returned `state=unknown` without error; push-hook `pnpm typecheck`, `pnpm lint`, and `pnpm format:check` all passed; push succeeded and `origin/docs/771-kbn101-db-role-split` resolved to that exact SHA. Pre-existing `.mosaic/orchestrator/{mission.json,session.lock}` remains modified but intentionally unstaged/excluded. The only next action is a fresh independent exact-head re-review.

-## 2026-07-15 — rc.10 Ultron NO-GO remediation intake
-
-- **Objective / scope:** Close only HIGH-1 and HIGH-2 in `/home/hermes/agent-work/reviews/771-kbn101-ultron-11f09a1.md` against exact head `11f09a15e43e72afda6a0374668996b4bda9e536`. Documentation only: preserve approved content; no source/config/Compose/CI/deploy/secret/migration edits and no `.mosaic` staging.
-- **Plan:** (1) replace the impossible `NOLOGIN NOSUPERUSER` extension owner with the exact non-login, zero-member `NOLOGIN SUPERUSER` external-control exception and document the non-delegable superuser residual; (2) require the audited external superuser session to `SET ROLE`/`RESET ROLE` for fresh, approved-owner, and shadow extension work, then prove catalog ownership and all service-role denial; (3) assign the active migrate-tier guide exclusively to KBN-101-07, add its active secure route to the -06 inventory/matrix/scanner schema, and freeze `--target-url-file /run/secrets/mosaic_migrate_target_url` plus pre-migrated target/dedicated non-DDL importer requirements; (4) synchronize PRD/shared/tasks/index/sitemap/guide and rc.10 status; (5) validate formatting, links, contracts, source paths, finite operator inventory, diff, review, commit, queue guard, push, and exact remote SHA.
-- **Target-image evidence before edits:** local `pgvector/pgvector:pg17` control file reports `default_version = '0.8.2'`, `relocatable = true`, and no `trusted`/`superuser` override (untrusted PostgreSQL extension). An isolated PostgreSQL 17 container proved a `NOLOGIN SUPERUSER` `mosaic_extension_owner` can create `mosaic_extensions` and `vector` under external-superuser `SET ROLE`, returns to the external session after `RESET ROLE`, has `rolcanlogin=false`, `rolsuper=true`, zero role members, exact extension/schema and owner-bearing-member ownership, and denies `SET ROLE`, `ALTER EXTENSION`, `DROP EXTENSION`, and schema ownership changes to runtime, migrator, schema owner, and data importer. Ownerless PostgreSQL catalog member classes (`pg_am`, `pg_cast`) were intentionally not misrepresented as ownable members.
-- **TDD decision:** skipped as not applicable: this is a documentation-only contract remediation. Future KBN-101-00/-02/-06 tests are specified as the situational evidence; no source/test artifact is permitted in this task.
-- **Final scope correction:** Per control-plane direction, remediation remains bounded to the two Ultron findings. The active guide is explicitly a non-operative KBN-101 contract until its owned implementation/activation lands; no additional design, source, CI, deployment, secret, or test artifact was added.
-- **Validation evidence:** target-image/container role proof PASS (pgvector `0.8.2`, `relocatable=true`, trusted absent/untrusted; external-superuser `SET ROLE`/`RESET ROLE`; exact extension/schema/owner-bearing-member ownership; zero membership and service-role denials). Changed-doc Prettier, strict native-kanban contract TypeScript, local-link resolver (8 docs), finite operator-doc inventory (one active KBN-101-07 route with no credential argv in executable blocks), source-path check (6 current paths), and `git diff --check` PASS. Pre-existing `.mosaic/orchestrator/{mission.json,session.lock}` remains intentionally excluded.
-
-## 2026-07-15 — rc.11 exact-head re-review remediation intake
-
-- **Objective / scope:** Close only HIGH-1 and HIGH-2 in `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview5-f60144e.md` against `f60144eb3eab6234ab01bda592052081c777897e`: target-bind the non-DDL tier importer with a runner-produced signed attestation, and disposition every current non-normative documentation scanner hit, including the active user-guide route and federation historical status. Documentation only; no source/config/Compose/CI/deployment/secret/migration edits and no `.mosaic` staging.
-- **Frozen decision:** `mosaic-db-migrator --verify` is trusted only after TLS/identity/manifest/schema verification and signs a credential-free JCS/Ed25519 v1 artifact from a runner-only fixed root-owned private-key file. The artifact binds secret version/exact URL-file digest, canonical TLS/CA/SPKI/server/database/importer/manifest/schema identity, issued/expiry/nonce, and producer build/correlation; importer gets pinned public key plus artifact only. It validates both files and all bindings before target connection, opens/digests/connects from one in-memory URL read, validates server identity before DML, and distinguishes zero connection from zero DML. Key overlap/revocation, secret-rotation invalidation, replay cache, atomic rename, and sanitized errors are mandatory.
-- **Ownership:** -03 owns producer/signing DTO/tests; -02 importer interface/verification tests; -05 key/artifact mounts/render tests; -06 inventory/matrix and non-masking scanner tests; -07 operator guide. The exact manifests remain disjoint.
-- **Operator correction:** `storage migrate` is schema-wrapper delegation only; legacy `--from hot --to cold` tier-copy guidance is unavailable. Secure tier copy is `migrate-tier` with `--target-url-file` plus `--target-attestation-file`. Federation M1 task language is status-only and adjacent KBN-101 text says it authorizes no current DDL.
-- **TDD decision:** skipped as not applicable: this bounded task changes documentation only. Future -02/-03/-05/-06 tests are specified as the required implementation evidence.
-- **Validation / review:** Prettier PASS on all 18 changed Markdown/root-doc files; `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json` PASS; changed-doc local-link resolver PASS (71 links); full current docs scanner/disposition PASS (10 non-normative paths, 4 normative-contract paths; no unknown active command); legacy `storage migrate --from` and raw target-URL bypass scan PASS; attestation field/interface assertion PASS; exact source ownership/manifest-overlap assertion PASS; `git diff --check`, docs-only scope, and secret-leak scan PASS. Manual documentation/security review verified key isolation, JCS/detached signature, secret-file hash as non-secret evidence, verification ordering/TOCTOU/replay/rotation, no connection vs zero DML, non-masking scanner class, status-only federation history, and no regression to pgvector closure. No source-code TDD applies.
-- **Delivery evidence:** committed `6227f076c819bd124383851633b16d4ef9c88a98` as `docs(#771): bind tier importer to verified target`; staged scope was 18 documentation files only and excluded `.mosaic`. Pre-push queue guard returned `state=unknown` without failure. Push hook ran repository `pnpm typecheck`, `pnpm lint`, and `pnpm format:check`: PASS. Branch push succeeded. Verify the exact remote SHA after this final delivery-evidence append, then idle for independent exact-head re-review and Ultron reverify. `.mosaic/orchestrator/{mission.json,session.lock}` remains pre-existing and excluded.
-
-## 2026-07-15 — rc.12 bounded deployable-importer/SETUP remediation plan
-
-- **Objective / scope:** Close the two HIGH findings in `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview6-65663d4.md` against exact head `65663d4f72f2ace5148bce9aeba04b5a8d5beee9`. Documentation/tracking only; preserve every earlier closure; do not modify source, deployment, Compose, CI, migration, Vault, or `.mosaic` artifacts.
-- **Plan:** (1) make KBN-101-05 own canonical KV-v2 importer URL/version provenance, separate immutable generation-pinned renderer consumers, importer CA/public-key/attestation mounts, fixed importer/migrator identities, safe-fd lifecycle, isolation/rotation/TOCTOU/error evidence, and -02/-03/-06 handoffs; (2) convert `docs/federation/SETUP.md` to a non-operative N-1 reference with only the required external-bootstrap → TLS/roles → runner `--run` → `--verify` → Gateway-readiness sequence; (3) broaden scanner grammar plus path-specific semantic negatives so indirect first-boot/startup/init/Compose authority cannot be masked by a named, normative, or status record; (4) synchronize PRD/shared/tasks/index/sitemap/federation task state and this scratchpad; (5) run formatting, links, strict contracts, complete-doc scanner/semantic assertions, diff/operator inventory, material/manifest overlap, review, docs-only stage, commit, queue guard, push, and exact remote-SHA verification.
-- **TDD decision:** skipped because this bounded change is documentation-only; the affected -02/-03/-05/-06 implementation tests and scanner semantic fixtures are specified as mandatory future evidence.
-- **Review correction:** independent Codex review found the initial `10003` producer → immutable `10002` importer artifact handoff impossible. rc.12 now specifies the required privileged deployment handoff controller: after runner success it safe-opens/verifies producer artifact plus generation, exact-byte copies/fsyncs/atomically renames to a distinct `10002:10002` `0400` importer mount, seals it read-only, and starts no importer on partial/wrong-generation/owner/mode failure. It receives only a root-owned non-secret expected-version/URL-digest/generation descriptor plus public verifier key, never URL bytes/private key; producer/importer share no writable file or mount. Dry-run nonce consumption now requires fresh `--verify` and artifact before `--yes`; the active-route schema requires `targetCredentialVersionFile`. Pre-existing `.mosaic` state is confirmed excluded from staging.
-- **Validation result:** changed-doc Prettier and `git diff --check` PASS; strict `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json` PASS; contract/SETUP material and non-operative semantic assertions PASS. Pending final docs-only stage, commit, queue guard, push, and remote-head verification.

-## 2026-07-15 — rc.13 MILESTONES semantic-scan remediation intake
-
-- **Objective / scope:** Close only HIGH-1 from `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview7-7365dcf.md` against `7365dcf15c09262a46132b9c011769ad98243641`. Documentation/tracking only: assign `docs/federation/MILESTONES.md` exclusively to KBN-101-07 and its exact former startup-extension wording to the KBN-101-06 semantic fixture/inventory; replace the wording with a non-operative historical/status disposition. No source, deployment, Compose, CI, Vault, migration, provider, or `.mosaic` artifact is authorized.
-- **Frozen remediation:** runtime/startup extension provisioning is superseded and forbidden. The sole eligible sequence is external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `mosaic-db-migrator --verify` → Gateway readiness. The MILESTONES record authorizes no current DDL, Compose/init, or startup path. The scanner must prove the exact former wording fails before any inventory/status-only mask and rerun its full current-doc operator/deploy-manifest scan outside reports/scratchpads.
-- **Plan:** update only MILESTONES plus the exact KBN-101 contract/inventory/manifests and necessary PRD/shared/task/index/sitemap/version/status references; run full lexical+semantic scan, Prettier, links, strict contract TypeScript, diff and manifest-overlap checks; stage docs only (excluding pre-existing `.mosaic`), commit, queue-guard, push, and verify the exact remote SHA. No source-code TDD applies because this bounded task changes documentation only.
-- **Remediation result (pre-commit):** `MILESTONES.md` now makes runtime/startup extension provisioning superseded and forbidden, with only external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `--verify` → Gateway readiness; it authorizes no current DDL/Compose/init/startup path. The KBN-101-07 manifest/inventory is exclusive and KBN-101-06 documents the exact former wording as a semantic negative that fails before inventory masking. Full current-doc scan outside reports/scratchpads: 103 Markdown files, 10 lexical-hit paths classified, 2 owned Compose-before-runner references, and zero ownerless indirect/literal routes. Prettier, strict native-kanban TypeScript, local links (64/0), diff check, and 95-path manifest-overlap reconstruction (0 overlaps; MILESTONES only -07) passed. Pre-existing `.mosaic/orchestrator/{mission.json,session.lock}` remains excluded.
-- **Delivery checkpoint:** committed remediation as `237bac81c93dc4305470cea23a67e4ced730bd61` (`docs(#771): close MILESTONES startup authority`). Push queue guard returned `state=unknown` without failure; the push hook ran repository `pnpm typecheck`, `pnpm lint`, and `pnpm format:check`, all PASS; the remote branch resolved to that exact SHA. This final evidence append is committed next, then the exact remote head is verified and the branch waits for independent exact-head rereview/Ultron reverify. `.mosaic` remains unstaged.
-
-## 2026-07-15 — rc.13 current-document safety remediation intake
-
-- **Objective / scope:** Close only HIGH-1 and HIGH-2 in `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview8-aeacc70.md` against exact head `aeacc702353740aad0f2f086974cc0670e360d1d`. This is documentation/tracking only. Preserve all prior gates; do not edit source, Compose, deployment artifacts, CI, migrations, Vault data, reports, or `.mosaic`.
-- **Source-backed decision:** Current `docker-compose.yml` mounts `infra/pg-init` into PostgreSQL init and that SQL creates `vector`; it cannot be used as a current PostgreSQL start route before KBN-101 bootstrap/runner artifacts exist. The checked-in configuration declares a supported `local` PGlite tier (`DEFAULT_LOCAL_CONFIG` and `tier-detection` both establish in-process PGlite with no external service probe), so docs may retain a local/PGlite route and start only non-PostgreSQL Compose services such as `valkey`.
-- **Plan:** (1) replace the README and dev-guide Compose-first PostgreSQL instructions with a PGlite/no-PostgreSQL developer path and an explicit held PostgreSQL/federated future activation sequence; (2) replace the deployment quick-start and bare-metal production procedure with non-operative status, no production `.env`/automatic dotenv/`EnvironmentFile`/credential export-or-argv/restart guidance, and only a non-executable future renderer/Vault generation-pinned process-exec or `LoadCredential` schematic; (3) expand KBN-101-06/-07 semantic fixture/disposition language to fail the exact former README/dev/deployment Compose-first sequences and production credential routes before ownership/status masking; (4) synchronize PRD/shared/tasks/index/sitemap/status/version and this scratchpad; (5) run formatting, links, strict contract TypeScript, full current-doc lexical+semantic scan outside reports/scratchpads, manifest-overlap, review, docs-only stage, commit, queue guard, push, and exact remote-SHA verification.
-- **TDD decision:** no source or fixture implementation may be changed in this documentation-only remediation. The -06 future fixture requirements are frozen as acceptance evidence; validation here is static semantic inventory plus documentation quality gates.
-- **Correction from independent review:** The initial local-Gateway PGlite wording was unsafe. `apps/gateway/src/main.ts` loads daemon/root/app-local environment files before tier selection; an inherited daemon `DATABASE_URL` can select PostgreSQL, whose current startup reaches extension creation and migrations. No source is authorized in this docs-only task. The remediation therefore holds Gateway/Web local startup, preserves only PGlite data-layer plus selected non-PostgreSQL Compose work, and assigns KBN-101-02 the fail-closed daemon/inherited/root/app-local DSN and non-local-tier rejection before connection/DDL, with a regression proof. The future renderer boundary remains KBN-101-05.
-- **Remediation evidence:** Removed active PostgreSQL Compose-first and production credential guidance from README, CLAUDE, dev/deployment, and the residual historical TUI/MCP routes; local documentation now permits only PGlite data-layer/non-PostgreSQL Valkey work while Gateway/Web startup is explicitly held. KBN-101-06/-07 now freeze exact former README/dev/deployment Compose sequences plus production credential patterns as pre-classification semantic negatives. Independent review surfaced the current daemon/root/app dotenv loader as an unsafe source boundary; no source is authorized here, so the docs hold that startup and assign fail-closed removal/regression proof to KBN-101-02.
-- **Validation:** Prettier PASS (12 changed docs); local-link resolver PASS (71 links); `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json` PASS; full README/CLAUDE/docs inventory PASS (104 documents, 0 active non-normative Compose/init/production-credential violations); manifest reconstruction PASS (10 cards, 95 declared path tokens, 0 overlaps); `git diff --check` PASS. Pre-existing `.mosaic/orchestrator/{mission.json,session.lock}` remains intentionally unstaged.
-- **Final route correction:** Held the residual MCP environment/restart and historical TUI smoke-test routes after review showed they could bypass the Gateway local-start hold; no bearer-token-over-HTTP or Gateway restart route remains in this remediation scope.
-- **Delivery:** committed `7cc156b777189ee89448e4d569a8b3f69560a240` (`docs(#771): hold unsafe database startup routes`) and `d8f935c20ade835aa3ec03fe5d6961885d8b5f0b` (`docs(#771): record final route correction`). Push queue guard returned `state=unknown` without failure; both pushes completed and the remote matched `d8f935c` before this final delivery-evidence append. `.mosaic/orchestrator/{mission.json,session.lock}` remains pre-existing and unstaged. Await a fresh independent exact-head re-review/Ultron verification.

-## 2026-07-15 — rc.15 exact one-finding runner/legacy-CI remediation intake
-
-- **Objective / scope:** Close only HIGH-1 in `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview9-be0ebfd.md` against `be0ebfdc6a2b32a0ab6989117ebbb12f43854d71`. Documentation/tracking only: no source, Compose, CI, deployment, migration, Vault, reports, or `.mosaic` edit.
-- **Plan:** Replace imperative current runner routes in the architecture plan and PERFORMANCE with one explicit non-operative future procedure; make fleet backlog current behavior PGlite-only and PostgreSQL held; classify README's checked-in direct CI `db:migrate` as legacy N-1/uncertified/non-authorizing pending KBN-101-06 removal; then extend the future KBN-101-06 lexical/semantic inventory contract so unqualified runner/current-CI authority fails before masking while only the complete named held procedure passes. Synchronize required contract/PRD/shared/task/index/sitemap state, run full docs scan and document gates, stage docs only, commit, queue-guard, push, and verify remote SHA.
-- **TDD decision:** not applicable: the user authorizes documentation only and the named -06 fixture/inventory files do not yet exist; the contract records their required future implementation evidence.
-- **Remediation / review closure:** Architecture, PERFORMANCE, federation SETUP/MILESTONES, deployment/dev/migrate-tier, and README now use one Markdown-bounded `Held future procedure` form where needed: non-operative/no-current-command-authority; KBN-101-00/-03/-05; external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `mosaic-db-migrator --verify` → Gateway/Compose readiness. Any runner hit outside that section is a -06 semantic failure. Fleet backlog current behavior is PGlite-only. README accurately records the checked-in direct CI migration as an active, isolated-disposable-database, uncertified legacy N-1 DDL exception that is non-authorizing as an operator route and pending -06 removal; it no longer falsely claims the current CI role lacks DDL capability. Independent Codex review found and this pass closed the readiness-endpoint, standalone-verify, CI-factuality, and scanner-boundary findings. Its only residual finding concerns pre-existing tracked `.mosaic/orchestrator` runtime state, which is explicitly excluded and unstaged by task scope; security review found no vulnerability.
-- **Validation:** changed-doc Prettier PASS; `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json` PASS; changed-doc local links 72/0; `git diff --check` PASS; full README/CLAUDE/docs lexical+semantic scan outside reports/scratchpads PASS (106 Markdown documents; 7 operator documents with runner tokens; zero unqualified future-runner/current-CI authority routes); KBN-101 manifest check PASS (10 dependency-ordered cards; -07 docs/-06 fixtures disjoint); docs-only allowlist PASS (16 docs, pre-existing `.mosaic` excluded).
-- **Delivery evidence:** committed `d857463a8a4658e34a77177737860cf82cc26ac6` (`docs(#771): hold unimplemented runner routes`). Pre-push queue guard returned `state=unknown` without failure; the push hook ran repository `pnpm typecheck`, `pnpm lint`, and `pnpm format:check`, all PASS. Push succeeded and `origin/docs/771-kbn101-db-role-split` matched `d857463a8a4658e34a77177737860cf82cc26ac6`. This evidence append is committed and pushed next; `.mosaic/orchestrator/{mission.json,session.lock}` stays pre-existing, unstaged, and excluded. Await exact-head independent re-review/Ultron reverify.

-## 2026-07-15 — rc.16 exact one-finding generic-wrapper remediation intake
-
-- **Objective / scope:** Close only HIGH-1 in `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview10-18e253c.md` against exact head `18e253c8790bdbb5bc30a06c116472213b83b22f`. Documentation/tracking only: no source, Compose, CI, deployment, migration, Vault, report, or `.mosaic` change.
-- **Source-backed correction:** `packages/storage/src/cli.ts` currently labels `storage migrate` a thin wrapper for `pnpm --filter @mosaicstack/db db:migrate` and executes that direct Drizzle command with `execSync`; no `mosaic-db-migrator` executable exists. Therefore the README commented form and user-guide executable form must not describe runner delegation or provide current command authority.
-- **Plan:** Remove the current wrapper command from README/user-guide command guidance; record it as legacy N-1, uncertified, non-operative, and forbidden pending KBN-101-02/-03/-06/-08 activation. Retain only the held future ordered bootstrap → TLS/roles → runner `--run` → `--verify` → readiness sequence and the separately held secure migrate-tier route. Extend KBN-101-06's future semantic fixture/matrix with both exact former forms (including the README commented code-fence form), requiring their failure before inventory/status masking and a source-consistency assertion that direct Drizzle wrapper source cannot be described as runner delegation. Synchronize status/version references only where required, then run document gates, stage docs only, commit, queue-guard, push, and verify the remote SHA.
-- **TDD decision:** not applicable: this bounded task changes documentation only; the required future -06 semantic/source-consistency fixtures are specified as implementation acceptance evidence.
-- **Remediation / validation:** README and user-guide remove the generic wrapper from command guidance and state the direct-Drizzle current-source truth, legacy-N-1/uncertified/non-operative MUST-NOT-INVOKE boundary, named -02/-03/-06/-08 activation cards, future external-bootstrap → TLS/roles → runner `--run` → `--verify` → readiness sequence, and separately held secure migrate-tier route. The KBN-101 rc.16 contract records both exact former forms (README commented code fence and user-guide executable code fence), requires failure before inventory/ownership/status masking, and requires the direct-Drizzle/no-runner-bin source-consistency proof. Prettier passed on all nine changed Markdown documents; changed-doc local links passed (72/0); strict native-kanban contract TypeScript and `git diff --check` passed; full README/CLAUDE/docs scan outside reports/scratchpads passed (106 documents, zero non-normative executable generic-wrapper or false runner-delegation route); and manifest validation passed (10 cards, 90 exact tokens, zero overlaps). Pre-existing `.mosaic/orchestrator/{mission.json,session.lock}` remains excluded.

-# Scratchpad — #791 Upgrade config protection (ms-791 worker lane)
-
-**Lane:** web1:ms-791 → reports to MS-LEAD (web1:mosaic-100). Do NOT contact Jason/Mos directly.
-**Worktree:** `/home/hermes/agent-work/stack-agents-dir-791`, branch `feat/791-upgrade-config-protection`
-off `origin/main` `9745bc3f` (verified exact head).
-
-## Mission prompt (verbatim intent)
-Protect operator-owned config under `~/.config/mosaic` from framework-upgrade wipes. Ratified
-combination (Mos-approved, do NOT re-litigate): (b) strict ownership separation [PRIMARY] + (a)
-transactional pre-update snapshot [safety net] + (d) regeneration-from-SSOT [recovery]. (c) periodic
-timer DEFERRED. HARD GATE: unit test that an upgrade run touches NO path outside the manifest.
-Design-first: write design doc, send to MS-LEAD, WAIT for confirmation before impl.
-
-## Session 1 (2026-07-16) — Phase 1 design
-
-### Evidence gathered (wipe mechanism, file/line)
-- `mosaic update` → `update-checker.ts:509` `buildReseedCommand` → `bash install.sh`
-  (`MOSAIC_SYNC_ONLY=1`, `MOSAIC_INSTALL_MODE=keep`).
-- Wipe = `packages/mosaic/framework/install.sh:199` `rsync -a --delete` + `PRESERVE_PATHS` denylist
-  (`install.sh:47`). cp-fallback `install.sh:223` `find ... -exec rm -rf`.
-- Denylist gaps → WIPED: `agents/*.conf`, `policy/*.md`, `*.local.md`, harvester/SOP,
-  `tools/_lib/credentials.json`.
-- Stale comment `update-checker.ts:492` claims `*.local` preserved — PRESERVE_PATHS has no such entry.
-- TS path `file-adapter.ts:157` → `file-ops.ts:66` `syncDirectory` = non-destructive copy-overlay, BUT
-  its preserve list (`file-adapter.ts:164`) already DRIFTED from install.sh (missing `fleet/backlog`,
-  `fleet/roles.local`). Evidence for single shared manifest SSOT.
-- Existing snapshot (`install.sh:76`) = /tmp, crash-trap only, deleted on success → inadequate; no
-  `mosaic restore`.
-- `fleet-reconciler.ts:93,234` already has `regenerate-projections-from-roster` phase separate from
-  lifecycle → `mosaic fleet regen` = thin projection-only wrapper (no restart), no FCM-M4/M5 preemption.
-
-### Design decisions
-- **(b)** Invert to allow-list: shared `framework/framework-manifest.json` (framework globs +
-  operatorReserved carve-outs); resolve per-path, deny-wins; **UNKNOWN ⇒ operator (fail-safe)**.
-  Mechanism: drop `--delete`; non-deleting bulk copy + explicit manifest-scoped prune pass (iterate
-  framework globs only → operator/unknown structurally unreachable). Pure prune-planner fn for tests.
-- **(a)** Snapshot to `~/.local/state/mosaic/backups/pre-update-<ts>/` 0700/0600, retention N=5,
-  post-sync verify+restore, `mosaic restore --list/--from`. No secret values in output.
-- **(d)** `mosaic fleet regen` projection-only, preview-first, never restart.
-- HARD GATE test includes a deliberately-unanticipated operator path to prove fail-safe default.
-- **PR split:** PR1 manifest+guard (root fix, ships alone) → PR2 snapshot/restore (secrev) → PR3
-  regen+docs. PR2/PR3 depend on PR1.
-
-### Status
-Design doc written: `docs/design/791-upgrade-config-protection.md`. Sent to MS-LEAD.
-
-## Session 1 (cont.) — MS-LEAD CONFIRMED → Phase 2 GO
-All 4 asks approved. Binding conditions:
-- TDD tests-first, red-first proof per PR; ≥85% new-code; co-located `*.spec.ts`; never `--no-verify`.
-- HARD GATE test (§2.4, unanticipated sentinel survives byte-identical + mtime unchanged) = MERGE-BLOCKING for PR1.
-- Manifest-completeness test (§6.2) required.
-- Bash+TS read ONE shared `framework-manifest.json`; parity test (§6.1) required (closes #631 drift class).
-- UNKNOWN⇒operator (rule 3) non-negotiable. Keep prune-planner PURE.
-- `fleet regen`: NEVER restart; dry-run default, `--write` to apply; "never issues restart" test mandatory.
-- Independent review every PR; PR2 dedicated secrev.
-- One PR at a time through DAG. Report PR1 exact head + red→green evidence for review commission.

-### Now: implementing PR1 (manifest + resolver + non-deleting sync + scoped prune + guard tests).
-
-## Session 2 (2026-07-16) — PR1 built, tests-first, red→green proven
-
-Deviation noted to MS-LEAD in PR: manifest is `framework-manifest.txt` (line-oriented), NOT `.json`.
-Rationale: keep the bash installer free of a python3/jq dependency. The "ONE shared file, parity-
-tested" requirement is honored — `manifest-parity.spec.ts` drives the bash resolver as a subprocess
-and asserts byte-identical ownership vs the TS resolver over 34 probe paths spanning every class.
-
-### PR1 artifacts
-- SSOT: `packages/mosaic/framework/framework-manifest.txt` ([framework]/[operator], deny-wins, fail-safe).
-- TS resolver: `src/framework/manifest.ts` (pure: parse/matchGlob/resolveOwnership/frameworkSubtreeRoots/
-  planPrune) + `manifest.spec.ts` (18 tests incl. planPrune property test + §6.2 completeness).
-- Bash resolver: `framework/tools/_lib/manifest.sh` (compiled globs → fork-free `manifest_is_framework`;
-  CLI `resolve|subtree-roots|classify`). Sourced by install.sh.
-- HARD GATE (§2.4): `framework/tools/quality/scripts/test-upgrade-manifest-guard.sh` — keep-mode reseed,
-  10 operator sentinels (incl. unanticipated `unknown-operator-dir/x`, `harvester/sop.md`,
-  `fleet/my-fleet.yaml`) survive byte-identical + mtime-unchanged; retired framework file pruned;
-  secret value absent from output. RED=31 fail (orig install.sh) → GREEN=48 pass (fixed).
-- install.sh: keep mode now manifest-driven (`sync_framework_keep`, no `--delete`); overwrite unchanged.
-  PRESERVE_PATHS denylist deleted.
-- TS sync: `file-ops.syncDirectory` gains `isOperatorOwned` guard; `file-adapter.syncFramework` derives
-  it from `loadManifest` — hardcoded (drifted) preservePaths deleted. Fixture uses the REAL manifest.
-- Parity: `manifest-parity.spec.ts` (§6.1) — bash↔TS agree on 34 paths + subtree roots.
-- Migration matrix `test-install-migration.sh`: F6 flipped — `my-fleet.yaml` now MUST survive (fail-safe).
-- CI: new merge-blocking `upgrade-guard` step (`.woodpecker/ci.yml`) runs both bash suites (adds rsync).
-- update-checker.ts reseed comment corrected to the manifest model.

-### MS-LEAD ruling → #797 ledger-survival sentinel folded into PR1 (2026-07-16)
-MS-LEAD ruled both my decisions: (1) `.txt` format ACCEPTED (parity must be strict/merge-blocking incl.
-format edge cases + negative probe); (2) trailer `Fixes #791`→`Part of #791` APPROVED (patched PR #802
-body via Gitea API — tracking issue no longer auto-closes on PR1 merge). Plus Mos-ELEVATED merge-blocker
-(spec `~/agent-work/planning/epic-796/791-ledger-survival-sentinel-SPEC.md`): #797 Runtime Session Ledger
-must survive upgrade. Two coupled deliverables landed in PR1:
-- (i) Carve-out: `fleet/run/**` was ALREADY an explicit `[operator]` entry — glob matches the spec's
-  pinned `fleet/run/**` EXACTLY, so NO divergence to route back to planner-opus. Strengthened its comment
-  to name the ledger (`fleet/run/sessions/` events.ndjson + ledger.json) so it is unmistakably load-bearing.
-- (ii) HARD-GATE sentinel: seeded populated ledger (events.ndjson 3 events + ledger.json node+edge+gen,
-  0600 under 0700) into test-upgrade-manifest-guard.sh sentinels; asserts byte-identical + mtime-unchanged
-  + dir-perms unchanged. Negative control (retired framework file IS pruned) relabeled explicitly.
-  HARD GATE now 58/58 (was 48).
-- Decision-1 parity hardening: format-edge fixtures (comments/blanks/whitespace, duplicate+overlapping
-  globs deny-wins, section/glob-ordering independence) + explicit UNKNOWN→operator negative probe, driven
-  through BOTH resolvers via MANIFEST_FILE override. Parity 7/7 (was 3).
-- RED-FIRST honesty note: the bash ledger sentinel stays GREEN even against the pre-fix installer (the
-  ledger was incidentally safe from the rsync --delete bug; overall pre-fix run 30/58 as expected). The
-  carve-out's TRUE load-bearing value (deny-wins if framework ownership ever broadens to `fleet/**`) is
-  isolated by a dedicated resolver-seam red→green in manifest.spec.ts: WITHOUT `fleet/run/**` operator
-  entry + hypothetical `fleet/**` framework → ledger resolves framework and planPrune DELETES it (RED);
-  WITH the carve-out → deny-wins → operator, unprunable (GREEN). manifest.spec.ts 21/21 (was 18).
-- Gates all green: typecheck ✓ lint ✓ format:check ✓ · full mosaic vitest 1069 passed · HARD GATE 58/58
-  · migration 21/21. Committing FORWARD on the branch (NOT rebasing 34e55d4a out from under review).

-### MS-LEAD REQUEST CHANGES @ 0a5e703a → B1/B2/B3 fixed red-first (2026-07-16)
-MS-LEAD returned REQUEST CHANGES (routed merge-blockers satisfied; 2 CRITICAL reliability defects from
-the commissioned independent review). Fixed forward on the branch, red-first:
-- **B1 (CRITICAL) — dead ERR trap.** install.sh had `set -euo pipefail` (no `-E`), so the
-  `trap restore_snapshot ERR` never fired for a failure inside sync_framework_keep() (function body) —
-  a mid-sync abort left a half-written target with NO rollback. Fix: `set -Eeuo pipefail` (errtrace) +
-  disarm the trap at the top of restore_snapshot() to prevent re-entrancy. New gate
-  `test-upgrade-rollback.sh`: injects a mid-sync `cp` EACCES (read-only divergent framework file);
-  Part A asserts the shipped installer rolls back (restore message fires AND target byte-identical to
-  pre-upgrade); Part B control strips `-E` and asserts the rollback message does NOT fire (dead trap) —
-  self-verifying red→green. 7/7.
-- **B2/B3 (CRITICAL) — empty/unreadable/malformed manifest divergence.** Pre-fix: TS `parseManifest('')`
-  returned `{framework:[],operator:[]}` (NO throw) → silent no-op "Installation complete"; bash aborted
-  fragilely (the `_manifest_compile` `"${MANIFEST_OPERATOR[@]:-}"` artifact returned 1 with no message)
-  AND the CLI dispatch swallowed manifest_load's rc (no `|| exit`) so `resolve` exited 0 resolving
-  everything operator. Fix (fail-loud + identical both langs):
-  * TS `parseManifest`: throw on zero framework entries; `loadManifest`: wrap read error →
-    "Cannot read framework manifest …".
-  * bash `manifest_load`: explicit unreadable guard (`[[ ! -r ]]`) + zero-`[framework]` guard, both loud
-    stderr + return 1; `_manifest_compile` gets explicit `return 0` (kills the empty-array artifact);
-    CLI dispatch `manifest_load … || exit 1`.
-  * `finalize.ts`: wrap syncFramework → `spin.stop('Framework sync aborted …')` + rethrow (never falls
-    through to "Installation complete").
-  Tests: manifest.spec.ts +5 fail-closed (empty/comment-only/operator-only/empty-section/missing);
-  manifest-parity.spec.ts +7 failure-mode parity (both reject empty/comment-only/operator-only/
-  empty-section/entry-before-header/unknown-header/missing — TS throws, bash CLI exits non-zero+stderr);
-  HARD GATE +4 end-to-end fail-closed matrices (empty/operator-only/malformed/missing → abort non-zero,
-  manifest error surfaced, every operator sentinel byte-identical). RED proven by reverting
-  manifest.ts+manifest.sh to HEAD → 12 new tests fail; restore → 40/40 green.
-- **Non-blocking addressed.** MEDIUM install.sh:222 find-empty now warns on a real failure instead of
-  blanket `|| true`. LOW: corrected the "both destructive paths rsync vs cp" overstatement in the HARD
-  GATE header + cp-fallback comment + ci.yml (keep mode is a single cp-based path; the rsync-present vs
-  -absent runs prove rsync-independence). `.pre-constitution.bak` triage: single-shot backup is
-  intentional (reconcile_framework_files backs up once), no change.
-- Gates: typecheck ✓ lint ✓ format:check ✓ · full mosaic vitest 1081 passed (was 1069, +12) · HARD GATE
-  118/118 (was 58) · rollback 7/7 (new) · migration 21/21. No --no-verify. Rollback test wired into
-  ci.yml upgrade-guard. Committing FORWARD (no rebase of 34e55d4a/0a5e703a).
-
-### Codex round 2 (pre-push self-review) → blockers A/B + should-fix C fixed red-first (2026-07-16)
-Before committing round 1 I re-ran codex on the change set; it surfaced two fresh reliability defects
-and one messaging defect on the SAME rollback/manifest path. Fixed forward, red-first:
-- **Blocker-A (CRITICAL) — signal trap resumed instead of terminating.** A bash INT/TERM handler that
-  merely `restore_snapshot` (returns) does NOT terminate the script — execution RESUMES past the
-  interrupt, cleans the snapshot and reports success, leaving a partial post-interrupt update. Fix:
-  `trap 'restore_snapshot; exit 1' ERR INT TERM` so both the errtrace (ERR) and signal (INT/TERM) paths
-  exit non-zero. Rollback test Part C: a `cp` shim that `kill -TERM $PPID` mid-sync then succeeds (so
-  set -e never fires and only the signal path governs) → asserts abort non-zero + restore fires + does
-  NOT print "file phase complete"; control strips `exit 1` and asserts the buggy resume-to-success.
-- **Blocker-B (CRITICAL) — degenerate `[framework]` section resolved everything operator.** A manifest
-  whose framework entries are all empty / bare-dot (`/`, `./`, `.`, `..`) passed the non-empty guard yet
-  yielded zero usable globs → nothing is framework → a keep-mode sync silently no-ops (bash resolved
-  `operator`, exit 0). Fix (both langs, parity): reject when no entry has a char other than `/`/`.` —
-  TS `isUsableFrameworkGlob` = `/[^/.]/.test(normalizeRel(glob))`, throws `ManifestError`; bash mirror
-  loops `[[ "$(_manifest_norm "$_g")" =~ [^/.] ]]`, loud stderr + return 1. Tests: manifest.spec.ts
-  `it.each(['/','./','.','..','/\n./'])` throw; parity +3 `expectBothReject` (root-slash/dot-slash/
-  bare-dot). RED: reverting the guard makes `[framework]\n/` resolve `operator` exit 0.
-- **Should-fix-C — misleading abort message.** finalize.ts printed one generic "may be partially
-  applied" for every sync failure. A `ManifestError` is a PRE-sync validation abort (manifest is
-  validated before any copy) → nothing was written; conflating it with a mid-copy failure misdirects
-  recovery. Fix: introduce `ManifestError` (exported from manifest.ts, thrown by every fail-closed
-  parse/load path), and classify in finalize.ts — ManifestError → "no files were changed"; any other →
-  "may be partially applied". New co-located `finalize-sync-abort.spec.ts` (3 tests) asserts both
-  branches re-throw the original error + the correct message, and that config writes are never reached.
-  RED proven by collapsing the classification → the ManifestError test fails.
-- Gates: typecheck ✓ lint ✓ format:check ✓ · full mosaic vitest 1094 (was 1081, +3 finalize-abort;
-  manifest specs already counted) · HARD GATE 193/193 · rollback 14/14 · migration 21/21.
-
-### Codex round 3 (pre-push self-review) → blockers D1/D2 fixed red-first (2026-07-16)
-Re-ran codex again; it found two more rollback-path gaps `set -E` cannot catch. Fixed forward, red-first:
-- **Blocker-D1 (CRITICAL) — `find` scan failures swallowed by process substitution.** Both the overlay
-  copy and the scoped prune consumed `< <(find … -print0)`. Bash does NOT propagate the producer's exit
-  status to the `while`, so an EACCES/I/O failure mid-scan truncates the file list yet leaves the loop
-  exiting 0 → a partial upgrade commits and reports success; the ERR/restore trap never fires. Fix:
-  `_scan_or_die` runs `find … -print0 > "$tmp"` to completion, checks its status, and returns non-zero
-  (→ ERR trap → restore) on failure; both loops now read from the checked temp file. Rollback test
-  Part D: a `find` shim that fails every `-print0` scan → shipped installer aborts non-zero + restores +
-  emits "Could not enumerate framework files" + target byte-identical; control neuters the `# D1-GUARD`
-  `return 1` → find failure swallowed, upgrade wrongly reports "file phase complete", no rollback.
-- **Blocker-D2 (CRITICAL) — silent `set -e` exit on a failed target reset.** restore_snapshot did a bare
-  `rm -rf "$TARGET_DIR"; mkdir -p "$TARGET_DIR"` (trap disarmed, under set -e). If `rm`/`mkdir` fails —
-  possibly after `rm` deleted part of the target — the script exits immediately, skipping the cp AND the
-  recovery pointer, leaving a half-removed target and an orphaned snapshot the operator can't locate.
-  Fix: `if ! rm -rf … || ! mkdir -p …; then fail "Snapshot restore could not reset … preserved at:
-  $SNAPSHOT_DIR — copy it back …"; return 1; fi` (tested like the cp -a check; snapshot NOT deleted).
-  Rollback test Part E: cp-poison triggers restore + an `rm` shim fails `rm -rf <TARGET>` → shipped
-  emits the recovery pointer, the named snapshot dir survives, secret value never leaked; control deletes
-  the recovery line → operator gets no pointer. RED: reverting D1+D2 → 7 shipped/control assertions fail.
-- Gates: typecheck ✓ lint ✓ format:check ✓ · full mosaic vitest 1094 · HARD GATE 193/193 ·
-  rollback 28/28 (was 14, +14 for D1/D2 with controls) · migration 21/21. shellcheck clean on new lines.
-  No --no-verify. Committing FORWARD (no rebase of 34e55d4a/0a5e703a).

-## Session 3 (2026-07-16) — PR1 MERGED, starting PR2 (durable snapshot + restore + secrev)
-PR1 (#802) squash-merged → main `32a0ffba`; issue #791 stays open (3-PR DAG umbrella). Independent Opus
-adversarial/security review APPROVED at head `af627e75` (Gitea RoR cmt 17892); lead ran rollback 28/28 +
-HARD GATE 193/193 green; CI #1877 green. PR2 UNBLOCKED.
-
-PR2 branch: `feat/791-pr2-snapshot-restore` off `origin/main` 32a0ffba. Same treatment applies:
-tests-first red-first, independent review + durable Gitea Reviewer-of-Record comment BEFORE MS-LEAD runs
-the queue guard/merge. Report PR2 number + exact head when ready. PR body: `Part of #791` (NOT Fixes).
-
-### PR2 scope (ratified §3/§5 of design doc, Mos-approved — do NOT re-litigate)
-- **(a) Durable pre-update snapshot** to `${XDG_STATE_HOME:-~/.local/state}/mosaic/backups/pre-update-<UTC-ts>/`
-  — OUTSIDE ~/.config/mosaic and any repo. Perms dir 0700 / files 0600 (umask 077 + explicit chmod).
-  Scope = operator-owned surface that EXISTS (operatorReserved paths), not the framework tree. Taken
-  BEFORE any mutation. Retention N=5 (`MOSAIC_BACKUP_RETENTION`), prune older.
-- **Post-sync verify + selective restore**: diff operator surface vs snapshot; (b) should never touch
-  operator paths, so ANY diff = manifest bug → restore affected paths + warn loudly. (a) catches a (b) miss.
-- **`mosaic restore`** (TS CLI): `--list` (default, dry-run) enumerates snapshots by ts; `--from <ts>`
-  restores over operator surface, confirmation-gated. Counts/paths only.
-- **Secret-safety (secrev)**: snapshot/restore NEVER emit file contents; only paths/counts. Tests assert
-  0700/0600 AND that a secret value seeded in tools/_lib/credentials.json never appears in any output.
-
-### PR2 implementation status (2026-07-16, ready-for-review)
-All three tasks implemented, red-first proven, unit-green:
-- **Task #10 — durable snapshot (install.sh)**: `backup_root()`/`enumerate_operator_files()`/
-  `prune_durable_snapshots()`/`make_durable_snapshot()` wired into keep-mode main() after `manifest_load`,
-  before any mutation. umask 077 + explicit chmod 700/600. UTC ts, collision suffix. FAIL-OPEN (a backup
-  failure never aborts the upgrade it protects). Retention `MOSAIC_BACKUP_RETENTION` (default 5), in-place
-  `sort -r -o` prune (no `mv` — stays inside the rsync-absent coreutils whitelist).
-- **Task #11 — post-sync verify net (install.sh)**: `verify_operator_surface()` runs after sync (trap
-  disarmed), `cmp -s` each snapshot file vs target; restores any diverged/missing operator file + warns
-  loudly (a divergence = manifest bug). VERIFY-NET wired before `cleanup_snapshot`.
-- **Task #12 — `mosaic restore` (TS)**: `src/commands/restore.ts` + co-located spec (19 tests).
-  `--list` default (dry-run enumerate), `--from <ts>` confirmation-gated restore, `--dry-run`, `--yes`/
-  `MOSAIC_ASSUME_YES`. Injectable `confirm` for testability (proceed/decline/env-bypass covered). Restored
-  files forced 0600. Registered in `cli.ts`. Path convention mirrors install.sh `backup_root()`.
-- **CI**: `.woodpecker/ci.yml` upgrade-guard runs the new `test-upgrade-durable-snapshot.sh` gate.
-- **Gates green**: typecheck ✓ lint ✓ format:check ✓ · full mosaic vitest 1241 (+5) ·
-  durable-snapshot 26/26 · manifest-guard 193/193 · rollback 28/28 · migration 21/21.
-  Est. new-code coverage ≈93% (only the interactive readline default + process.exit-on-error uncovered).
-- Regression fixed: PR2's `date`/`sort`/`mv` broke the rsync-absent manifest-guard PATH whitelist →
-  made date/sort fail-open, replaced `mv` with in-place `sort -o`, added `date sort` to the test whitelist
-  + isolated `XDG_STATE_HOME`. All 193 manifest-guard assertions green under restricted PATH.
-- Codex code-review + security-review (secrev) run on the uncommitted diff before commit.
-
-### PR2 review round 1 — findings + remediations (2026-07-16, pre-PR)
-Codex code-review returned **request-changes** (1 blocker + 3 should-fix); Codex security-review returned
-**high** (1 high + 1 medium). Deduped to 5 distinct defects, ALL legitimate, ALL fixed FORWARD, each with
-a red-first regression test whose control neuters exactly the guard under test:
-
-- **A · BLOCKER — verify net undid the legacy bin/ migration (install.sh).** On a pre-v2 install `bin/**`
-  is operator-classified, so the durable snapshot captured it; `run_migrations()` deletes bin/ on purpose,
-  but `verify_operator_surface()` then saw it "missing" and healed it back — the migration would be silently
-  undone forever once the version stamps. **Fix:** `MIGRATION_REMOVED_PATHS[]` recorded by run_migrations
-  (`bin`,`rails`) + `is_migration_removed()` skip in the verify loop (`# MIGRATION-SKIP-GUARD`).
-  **Test:** Part 6 — v1 fixture with bin/; shipped keeps it removed + stamps v3; control (guard stripped)
-  wrongly restores bin/tool.sh.
-- **B · HIGH (CWE-59) — restore/verify wrote secrets THROUGH a symlink (install.sh + restore.ts).** An
-  attacker swapping an operator path (e.g. tools/_lib/credentials.json) for a symlink after the snapshot
-  would make `cp`/`copyFileSync` write the snapshot's secret out through the link. **Fix (bash):** refuse a
-  symlinked ancestor (`has_symlinked_parent`), drop a symlinked leaf before restore
-  (`# SYMLINK-LEAF-GUARD`). **Fix (TS):** reuse audited `secure-file.ts` — `assertCanonicalContainment`
-  + `ensureManagedDirectory` on every dst, open the leaf `O_NOFOLLOW|O_CREAT|O_TRUNC` 0600 (ELOOP =
-  fail-closed). **Tests:** Part 7 (shipped leaves external exfil target untouched, restores a real 0600
-  file; control leaks the secret through the link) + restore.spec symlinked-leaf/ancestor cases (red-first).
-- **C · MEDIUM/should-fix (CWE-22) — `--from` traversal escaped the backup root (restore.ts).**
-  `join(root, from)` accepted `../poison`. **Fix:** validate the selector against
-  `^\d{8}T\d{6}Z(?:-\d+)?$`, build exactly `join(root,'pre-update-'+ts)`, `lstat` (reject symlinked snap
-  dir). **Test:** restore.spec `it.each` of 6 malformed selectors + `--from ../poison` fail-closed (red-first).
-- **D · should-fix — verify `mkdir -p` unguarded under set -e (install.sh).** A parent replaced by a
-  regular file aborted the installer before the recovery pointer printed. **Fix:** guard `mkdir -p`, warn

-
-### Independent review (3 reviewers: subagent code-reviewer + codex code-review + codex security) → 4 fixes, red-first
-- **A · BLOCKER (codex) — regen mutated/deleted legacy operator env.** `applyPreparedAgentEnvironmentProjection`
-  also writes `.env.local`/`.env.quarantine` and unlinks legacy `.env`. Violated projection-only contract.
-  **Fix:** NEW generated-only boundary primitives `prepareGeneratedAgentEnvironmentProjection` +
-  `applyPreparedGeneratedAgentEnvironmentProjection` (write ONLY `<name>.env.generated`). regen now has no
-  code path that touches `.env`/`.env.local`/`.env.quarantine`. **Test:** projection-only leaves legacy `.env`
-  verbatim, no local/quarantine fabricated.
-- **B · should-fix (codex + subagent + security) — partial write on mid-loop failure.** Interleaved
-  prepare/apply left earlier agents written when a later agent failed prepare. **Fix:** PREPARE ALL agents
-  before writing ANY (mirrors reconciler `defaultPrepareProjections`). **Test:** 2nd agent's projection
-  pre-seeded 0644 → prepare rejects → coder0 NOT written, exit 1.
-- **C · subagent — semantic-validation bypass.** Default readRoster skipped `validateRosterV2Semantics`, so
-  a tampered protected-class `tool_policy` would be silently projected. **Fix:** default readRoster now runs
-  `validateRosterV2Semantics` (persona resolution + protected-class match), rolesDir/overrideDir defaults
-  mirroring the reconciler. **Test:** merge-gate agent w/ tool_policy=code → fails closed, no write.
-- **D · MEDIUM (codex security, CWE-362) — concurrent-reconcile race.** regen `--write` wrote without the
-  reconcile lock. **Fix:** `--write` acquires `acquirePrivateReconcileLock(mosaicHome)` for the whole
-  read-prepare-apply sequence, released in `finally`; dry-run stays lock-free. **Test:** pre-held lock →
-  regen fails closed, no write.
-
-**Gate suite after fixes (all green):** typecheck ✓ · lint ✓ · format:check ✓ · full mosaic vitest **1265**

-
-## Session 5 — PR3 review round 2 (finding L + M1/M2/M3), red-first fixes
-
-Second review pass on the lock-cleanup plumbing surfaced one round-1 residual (L) and three round-2
-findings (M1 blocker, M2/M3 should-fix). All fixed red-first (RED proven per-finding, then GREEN).
-
-- **L · should-fix (codex r1) — mutation-lock release swallowed unlink failures.** regen's
-  `acquirePrivateRosterMutationLock` release copied CRUD's `unlink().catch(()=>{})`, hiding a stale
-  `roster.yaml.mutation.lock`. **Fix:** its release PROPAGATES the unlink fault (finding-J stale-lock
-  warning then fires for this lock too). **Test:** acquire real lock, `rm` it, assert `release()` rejects.
-- **M1 · BLOCKER (codex r2) — replacement-lock race.** The propagating release from L did an
-  UNCONDITIONAL `unlink(lockPath)` without proving ownership. If the lock is cleared + re-created by
-  another writer mid-op, regen deletes the STRANGER's live lock → a third writer enters → mutual
-  exclusion defeated. **Fix (reuse, not reimplement):** generalized the reconciler's ownership-proving
-  lock body into shared `acquirePrivateManagedRosterLock(mosaicHome, lockLeaf, busyMessage, openLock)`;
-  `acquirePrivateReconcileLock` delegates to it (behavior-identical: same leaf/codes/messages), and a NEW
-  hardened `acquirePrivateRosterMutationLock` (now in fleet-reconciler.ts, leaf `roster.yaml.mutation.lock`)
-  records dev/ino + ownership token and RE-PROVES ownership (`assertLockOwnership`) before unlinking —
-  fails closed as `lock-cleanup-failed` if replaced. Removed the crud-based export; reverted
-  `acquireMutationLock` (fleet-agent-crud.ts) to its original inline empty-file/swallowing-release form
-  (CRUD behavior intentionally unchanged). Compatibility: CRUD empty-file `wx` and regen tokened `wx`
-  contend on the same path but never co-own (wx winner owns; loser → concurrent-mutation), so the token
-  is only ever read back by the same regen invocation. **Test:** acquire, `rm`+recreate lock (new inode),
-  assert `release()` rejects AND the replacement survives (not unlinked).
-- **M2 · should-fix (codex r2) — acquire-unwind fault dropped.** The acquire-failure catch discarded
-  `releaseFleetLocks`' return (a possible fault on the already-held first lock). **Fix:** capture and
-  augment — `const releaseFault = await releaseFleetLocks(releases); throw augmentWithLockCleanupFault(error, releaseFault);`
-  (symmetric to finding J). **Test:** mutation lock acquires w/ faulting release + reconcile acquire
-  throws → thrown error mentions stale/lock, nothing written.
-- **M3 · should-fix (codex r2 + subagent REQUEST-CHANGES) — cleanup warning named only reconcile lock.**
-  Finding L made the mutation-lock release fault reachable, so the `cleanup` marker can originate from
-  EITHER lock. **Fix:** `formatFleetRegenReport`'s WARNING now names BOTH `roster.yaml.mutation.lock` and
-  `roster.yaml.reconcile.lock`, matching `augmentWithLockCleanupFault`. **Test:** fault the mutation-lock
-  release specifically → report names both lock files.
-
-**Refactor note (no cycle):** neither fleet-reconciler nor fleet-agent-crud imports the other; regen
-imports lock acquirers from fleet-reconciler and the projection mapping from fleet-reconciler. The two
-reconcile-lock reviewers reconciled: independent reviewer validated acquire-time empty-file compatibility
-(preserved), codex flagged RELEASE-time replacement race (closed by ownership proof) — non-contradictory.
-
-**Gate suite after fixes (all green):** typecheck ✓ · lint ✓ · format:check ✓ · full mosaic vitest **1275**
-(regen spec 23, incl. 7 red-first lock regressions E/F/G/K/L/M1/M2/M3). RED proven per-finding by
-temporary revert before re-applying each fix. Independent (author≠reviewer) review of M1/M2/M3 + codex
-code/security re-run in flight. STOP at PR-open for MS-LEAD's exact-head review + durable Gitea RoR; do
-NOT self-merge; #791 umbrella stays OPEN; PR body `Part of #791`.
-
-### Round 3 review (after M1/M2/M3) — independent review PASS + codex residual-TOCTOU disposition
-Three reviewers on the post-M1/M2/M3 head:
-- **Independent (subagent, author≠reviewer) — PASS.** Verified M1/M2/M3 all correctly fixed; "never
-  restarts" is STRUCTURAL (runner never referenced in executable code); no secrets; no deadlock (only
-  regen holds both locks); tests meaningful (assert inode preservation + exact lock-file names). Raised:
-  - **should-fix #1 (fixed, red-first):** generalizing the lock helper left `assertSafeLockLeafIfPresent`/
-    `assertLockOwnership` hardcoding "reconciliation lock" in thrown messages → a MUTATION-lock fault
-    misreported as the reconcile lock, undercutting M3's accurate-diagnosis goal. **Fix:** thread
-    `lockLabel = fleet/<leaf>` through both helpers + the generic lock-io messages, so every fault names
-    the actual lock file. Red-first: strengthened the M1 test to assert `/roster\.yaml\.mutation\.lock/`
-    (RED: got "reconciliation lock"; GREEN after). Also resolves nit #3 (generic-message drift).
-  - **nit #2 (fixed):** `FleetRegenResult.cleanup` JSDoc still said "the shared reconcile lock"; now names
-    both locks (regen holds both).
-  - **nit #4 (fixed):** removed the redundant duplicate `assertLockOwnership` call before unlink
-    (pre-existing in merged main; harmless but dead — dropped since the fn was already being touched).
-- **Codex security — clean (risk: none).** Validates roster semantics, constrains env values, no shell
-  eval, no secret output, generated-only writes, serialized against both locks.
-- **Codex code — request-changes, 1 "blocker": residual check-then-unlink TOCTOU.** Between the final
-  `assertLockOwnership` and the path-based `unlink`, an external actor could vacate our inode and a new
-  writer grab the path, so the unlink deletes the stranger's lock. **Disposition: documented known
-  limitation, NOT fixed in PR3.** Rationale: (1) byte-identical to the MERGED, shipped reconcile-lock
-  release on origin/main (fleet-reconciler.ts L654-659) — not introduced here; (2) UNREACHABLE within the
-  `wx` writer protocol — no Mosaic writer removes a lock it doesn't own (wx fails EEXIST while our inode
-  exists), so only external interference can vacate our inode in the sub-instruction window; (3) the
-  ownership guard DOES close the reachable case (stale-lock reaper/operator cleared our lock + another
-  writer took it BEFORE release began → fail closed, don't delete stranger's lock); (4) the true atomic
-  fix — fd-held advisory lock (flock/lockf) adopted by ALL fleet writers (CRUD + reconcile + regen) — is
-  a cross-cutting mechanism change touching merged CRUD + reconciler, out of scope for a projection-only
-  recovery PR. Documented honestly in the acquirer doc + M1 test comment. **The binding independent
-  review did NOT treat this as a blocker.** Recommendation to MS-LEAD: proceed to PR-open + spin a
-  SEPARATE follow-up issue for the fd-advisory-lock migration; MS-LEAD adjudicates scope at exact-head
-  review (merge authority).
-
-**Gates after round-3 fixes (all green):** typecheck ✓ · lint ✓ · format:check ✓ · full mosaic vitest
-**1275** (regen spec 23). Fresh codex code re-run in flight to confirm no NEW issues from the label fix.
-

-
-## Session 6 — Round 4/5 convergence (stranded-lock robustness)
-
-**Two independent reviewers converged on the SAME should-fix** on the init-failure cleanup path,
-strengthening confidence it was real:
-
-- **Codex code-review-5 — 0 blockers, 1 should-fix.** "Stat failure after lock creation strands the new
-  lock." When `handle.stat()` ITSELF fails right after the `wx` create (transient EIO/EBADF), `created`
-  is `undefined`, so `removeOwnedLockLeafBestEffort` had `if (!created) return;` → no cleanup → the
-  just-created `roster.yaml.mutation.lock`/`reconcile.lock` is stranded, permanently blocking future
-  regen + CRUD. (Notably NO blocker, and the TOCTOU is no longer flagged in code-review as of r5.)
-- **Independent delta reviewer (author≠reviewer, pr-review-toolkit) — no blockers, same should-fix.**
-  Independently flagged the identical `!created` gap; validated FIX 1 (label threading — no call site
-  missed, codes unchanged, no test depended on old text) and FIX 2 (dev/ino-guarded cleanup, best-effort,
-  happy-path release reuses captured dev/ino) as correct. Suggested an unconditional best-effort unlink
-  in the `!created` branch; I took the **safer** variant below.
-- **Codex security-review-5 — 0 crit / 0 high / 1 medium.** The single medium is the SAME residual
-  check-then-unlink TOCTOU already dispositioned in round 3 (its own remediation = "migrate every writer
-  to an fd-held advisory lock" = the follow-up issue). No new security finding. No secrets.
-
-**Fix (red-first, safer than an unconditional unlink):** thread the persisted random `token` into
-`removeOwnedLockLeafBestEffort`. Two independent ownership proofs now: primary dev/ino (unchanged), and a
-**fallback** when the post-create stat failed — read the leaf and unlink ONLY if its content equals our
-`randomUUID()` token. Only OUR lock carries that token, so a CRUD (empty) or differently-tokened
-replacement is never deleted. `tokenPersisted` guards passing the token (only after `writeFile` lands).
-Doubly-degenerate case (stat fails AND token write never landed) leaves the lock in place rather than
-risk deleting a stranger's file — requires two independent fs faults on a just-created fd; documented.
-
-- **Red-first proof:** new test `does not strand the lock file when the post-create stat itself fails`
-  injects a real `wx` create + a Proxy handle whose `stat()` rejects (writeFile/close succeed), asserts
-  `exists(lockPath) === false`. RED before fix (`expected true to be false` — lock stranded); GREEN after.
-- **Also fixed (delta nit #3):** `fleet-regen-command.ts` `acquireRosterMutationLock` JSDoc said "CRUD's
-  private lock"; the default is the reconciler's hardened ownership-proving acquirer for the same
-  `fleet/roster.yaml.mutation.lock` path. Corrected.
-- **PR-description note (delta nit #2):** FIX 1 also collapsed a pre-existing duplicate back-to-back
-  `assertLockOwnership` call in the release closure (identical args, no intervening logic) into one — a
-  no-op simplification of merged code, not a behavior change. Called out so a future reader doesn't
-  wonder if the duplicate had a purpose.
-
-**Gates after round-4 fixes (all green):** typecheck ✓ · lint ✓ · format:check ✓ · full mosaic vitest
-**1277** (regen spec now 25: +1 stat-failure stranded-lock regression). Residual TOCTOU still deferred to
-the fd-advisory-lock follow-up issue; MS-LEAD adjudicates scope at exact-head review (merge authority).
-
----
-
-## Session 6 — Round 6 (persona-root wiring)
-
-**Codex code-review-6 — 0 blockers, 1 should-fix (NEW, distinct from the lock work).** "Forward
-configured persona directories to regen." `registerFleetRegenCommand` was registered at
-`fleet.ts:2069` with only `{ runner, mosaicHome }`, discarding `deps.reconcileDeps.rolesDir` /
-`overrideDir`. The regen command ALREADY has those seams (validates roster semantics via
-`validateRosterV2Semantics({ rolesDir, overrideDir })`, defaulting to `<mosaicHome>/fleet/roles{,.local}`),
-but the top-level wiring never forwarded the configured roots. **Impact:** in a deployment with custom
-persona roots, `fleet reconcile` (which honors the overrides) would ACCEPT a roster while `fleet regen`
-REJECTS the same roster (persona resolution against the wrong default dir) — blocking the recovery
-command and violating the documented "resolves personas the SAME way reconcile does" contract.
-
-**Fix (red-first):** forward `rolesDir`/`overrideDir` from `deps.reconcileDeps` into
-`registerFleetRegenCommand` at `fleet.ts:2069`. Red-first test `forwards configured persona roots
-(rolesDir/overrideDir) from reconcileDeps into regen`: seeds personas ONLY under a custom root, leaves
-the default `<home>/fleet/roles` empty, registers with `reconcileDeps: { rolesDir, overrideDir }`, and
-requires `fleet regen` to SUCCEED. RED before fix (`expected 1 not to be 1` — regen validated against the
-empty default and exited 1); GREEN after.
-
-**Codex security-review-6 — 0 crit / 0 high / 1 medium.** Same residual check-then-unlink TOCTOU, now
-noted at BOTH the release closure and the init-cleanup path; remediation = fd-held advisory lock across
-all writers = the SAME deferred follow-up item. No new security finding, no secrets.
-
-**Independent confirmation review of the token-fallback fix (Session 6/round 4) — PASS, no findings.**
-All 7 verification points confirmed; reviewer mechanically reverted `removeOwnedLockLeafBestEffort` to
-the pre-fix `if (!created) return;` and re-ran the new test → RED (`expected true to be false`),
-confirming the test genuinely pins the fix; restored after. No lint/type issues; doc-comment accurate.
-
-**Gates after round-6 fix (all green):** typecheck ✓ · lint ✓ · format:check ✓ · full mosaic vitest
-**1278** (regen spec now 26: +1 persona-root wiring regression).
-
----
-
-## Session 6 — Round 7 convergence (review CLOSED for PR-open)
-
-- **Codex code-review-7 — 0 blockers, 1 should-fix = the residual TOCTOU** (previously a "blocker" in r3,
-  dropped in r4/r5, now re-surfaced as a should-fix). **Codex security-review-7 — 0 crit / 0 high /
-  1 medium = the SAME residual TOCTOU.** Codex has CONVERGED: the only remaining finding across both
-  streams is that one race, whose own remediation is "fd-held advisory lock shared by all fleet writers"
-  = the deferred follow-up. No new distinct finding; the wiring fix introduced nothing.
-- **Independent confirmation review of the persona-root wiring fix — PASS, no findings.** Reviewer
-  mechanically reverted the two forwarded lines → RED (`Roster v2 agent "coder0" class "code" does not
-  resolve to a readable persona` → exit 1), restored → GREEN (26 regen + 204 fleet tests). Confirmed the
-  optional-chaining fallback preserves default-deployment behavior and no type/lint issue.
-
-**Review disposition for PR-open:** ALL actionable findings fixed red-first across rounds 3–6 (label
-threading, stranded-lock on init failure, stat-failure strand, persona-root wiring). The residual
-check-then-unlink TOCTOU is the ONLY open item and is DEFERRED to a follow-up issue (fd-advisory-lock
-migration across CRUD + reconcile + regen) — byte-identical to merged origin/main's reconcile-lock
-release, unreachable within the `wx` writer protocol (no Mosaic writer removes a lock it doesn't own;
-only external `rm`/a stale-lock reaper can vacate the inode mid-release), and its true fix is a
-cross-cutting mechanism change out of scope for a projection-only recovery PR. Two independent human-agent
-reviews (author≠reviewer) treated it as non-blocking. MS-LEAD adjudicates scope at exact-head review
-(merge authority); recommendation = proceed to PR-open + spin the follow-up issue.
-
-**Final gates (all green):** typecheck ✓ · lint ✓ · format:check ✓ · full mosaic vitest **1278**
-(regen spec 26). No secret values in any snapshot/projection/report output (counts + paths only). Regen

-# Issue #804 — fail closed on unknown installer arguments
-
-## Objective
-
-Implement Part 1 of Gitea issue #804 only: `tools/install.sh` must reject every unrecognized flag or argument with an actionable STDERR error and nonzero exit before installation starts.
-
-## Scope and constraints
-
-- Preserve all currently recognized options and behavior, including `-y` and `--ref <branch>`.
-- No positional arguments are currently accepted by the parser.
-- Do not add `--next`, `MOSAIC_NEXT`, prerelease routing, or any Part 2 behavior.
-- TDD is mandatory: add and observe a failing process-level regression test before changing `tools/install.sh`.
-- Worker lifecycle ends after branch push, PR creation, and coordinator notification; do not merge or close #804.
-- Existing launcher-owned changes in `.mosaic/orchestrator/mission.json` and `.mosaic/orchestrator/session.lock` are out of scope and must not be committed.
-
-## Requirements and acceptance criteria
-
-- Unknown input names the offending argument on STDERR.
-- STDERR includes a short installer usage hint.
-- Exit status is nonzero.
-- The installer does not invoke npm or otherwise proceed into installation.
-- Existing recognized flags remain unchanged.
-
-## Plan
-
-1. Add a process-level Vitest regression using the installer test location under `packages/mosaic/src/commands/`.
-2. Run the focused test and record the expected RED failure.
-3. Commit the RED test as `test(#804): ...`.
-4. Replace the parser catch-all with a fail-closed STDERR error and usage hint.
-5. Update concise installer-facing documentation without introducing prerelease behavior.
-6. Run focused tests, shell syntax validation, package tests, lint, typecheck, and format checks.
-7. Run independent review tooling and remediate findings.
-8. Commit as `fix(#804): ...`, queue-guard, push, open a PR containing `Closes #804.`, notify the coordinator, and exit.
-
-## Budget
-
-- No explicit token cap supplied.
-- Working estimate: 8K tokens; narrow two-file behavior/test change plus concise docs and delivery gates.
-
-## Progress
-
-- 2026-07-17: Loaded mission state, issue #804, delivery/QA/documentation rails, and relevant TDD/Vitest/pnpm/Gitea skills.
-- 2026-07-17: Confirmed the parser has no legitimate positional arguments and currently drops all unmatched input via `*) shift ;;`.
-- 2026-07-17: Installed locked workspace dependencies with a worktree-local pnpm store; no lockfile changes.
-- 2026-07-17: Added the process-level unknown-argument regression with an isolated `$HOME` and npm shim.
-- 2026-07-17: Replaced the silent catch-all with STDERR error + usage output and exit 2 before preflight or installation.
-- 2026-07-17: Initial Codex code review found an unknown option could still be consumed as the `--ref` value. Added a second RED reproducer, then rejected option-shaped/missing `--ref` values without changing valid `--ref <branch>` behavior. The review's launcher-state note is handled by excluding both `.mosaic/orchestrator/` files from commits.
-- 2026-07-17: Updated README, user guide, and packaged framework README with the fail-closed argument contract. No API, auth, admin, sitemap/navigation, or publishing surface changed.
-
-## Verification
-
-- RED: `pnpm --filter @mosaicstack/mosaic exec vitest run src/commands/install-arguments.spec.ts` — expected failure: installer exited `0` instead of nonzero at the exit-status assertion; confirms the test reproduces the silent-drop defect before production changes.
-- Remediation RED: the added `--cli --ref --bogus` case exited `0`, proving `--ref` could swallow an unknown option before the guard was added.
-- GREEN: `pnpm --filter @mosaicstack/mosaic exec vitest run src/commands/install-arguments.spec.ts src/commands/install-heading.spec.ts` — 2 files, 3 tests passed.
-- Situational process check: unknown positional input exited 2, named the input on STDERR, printed usage, and did not call the npm shim.
-- `bash -n tools/install.sh` — passed.
-- Bare `--ref` process check — exited 2 with `Missing value for --ref` and usage.
-- `pnpm --filter @mosaicstack/mosaic test` — 69 files, 1,287 tests passed; framework shell checks passed. The first attempt lacked generated `dist/cli.js`; `pnpm --filter @mosaicstack/mosaic build` restored the required test precondition and the full rerun passed.
-- `pnpm lint` — 23/23 tasks passed.
-- `pnpm typecheck` — 42/42 tasks passed.
-- `pnpm format:check` — passed.
-- Codex code re-review against `origin/main` — `approve`, 0 blockers/should-fix/suggestions.
-- Codex security re-review against `origin/main` — risk `none`, 0 findings.
-
-## Acceptance evidence
-
-| Criterion | Evidence |
-| --- | --- |
-| Unknown input is named on STDERR | Process-level Vitest assertions for `--bogus`, including after `--ref` |
-| Short usage hint is printed on STDERR | Vitest usage regex + manual process output |
-| Exit is nonzero | Vitest status assertions and manual exit 2 |
-| Installation does not proceed | Isolated npm shim marker remains absent |
-| Recognized behavior is preserved | Parser cases are unchanged except validation of malformed `--ref`; full Mosaic package suite passed |
-| Part 2 is excluded | No `--next`, `MOSAIC_NEXT`, dist-tag, or prerelease routing changes |
-
-## Documentation checklist
-
-- Current canonical `docs/PRD.md` remains unchanged; issue #804 and the coordinator brief supply this bounded defect's acceptance contract.
-- Updated installer behavior in root README, user guide, and packaged framework README in the same logical change set.
-- API/OpenAPI, auth/permissions, admin operations, developer architecture, sitemap/navigation, and external publishing are not affected.
-- Scratchpad remains under `docs/scratchpads/`; no root-hygiene changes.
-
-## Risks and blockers
-
-- Part 2 remains owner-gated under #805 and is intentionally excluded.
-- No implementation blocker remains. Independent coordinator RoR, CI, merge, and issue closure remain pending after worker handoff.

-# Issue #807 — GLPI list wrappers accept HTTP 206
-
-- **Branch:** `fix/807-glpi-206`
-- **Task:** Gitea issue #807
-- **Role:** Author-only worker reporting to `mosaic-100`; no self-review or merge
-- **Started:** 2026-07-16
-
-## Objective
-
-Fix the shipped GLPI ticket, computer, and user list wrappers so ranged responses with HTTP 206 Partial Content render successfully while genuine HTTP failures remain non-zero errors.
-
-## Scope
-
-- Modify only the three affected list wrappers and a focused shell regression test.
-- Do not touch `session-init.sh`, `ticket-create.sh`, or `docs/TASKS.md`.
-- Add task-local delivery evidence here as required by the mission protocol.
-
-## Plan
-
-1. Add a deterministic shell harness that copies each wrapper beside stubbed `session-init.sh`, credentials, and `curl` boundaries.
-2. Prove RED against the current 200-only gates: 206 must fail before the implementation change.
-3. Update all three status gates to accept exactly 200 or 206.
-4. Prove GREEN for 206 rendering and genuine 401/500 failures, then run repository quality gates.
-5. Commit with co-author attribution, run the push queue guard, push, and open a PR for independent review and merge by the team lead.

-## Budget
-
-- No explicit token cap supplied.
-- Soft estimate: 8K tokens; narrow single-worker execution with no exploratory scope.
-
-## Progress
-
-- [x] Mission, task, PRD, QA, documentation, and code-review guidance loaded.
-- [x] RED regression evidence captured: `test-list-http-status.sh` exited 1; all three wrappers rejected 206 while retaining 401 failures.

-- GREEN: `pnpm typecheck` → 42/42 tasks pass.
-- GREEN: `pnpm lint` → 23/23 tasks pass.
-- GREEN: `pnpm format:check` → all matched files pass.
-- Setup note: initial gate attempts could not start because the fresh worktree lacked dependencies; `pnpm install --frozen-lockfile --store-dir /home/hermes/.local/share/pnpm/store` restored the locked workspace dependencies without lockfile changes.

-## Acceptance criteria mapping
-
-| Criterion | Evidence |
-| --- | --- |
-| HTTP 206 succeeds and renders each ranged list | Focused test's three 206 render assertions pass |
-| Genuine HTTP failures remain non-zero with existing diagnostics | Focused test's three HTTP 401 assertions pass |
-| Only affected list wrappers change | Diff contains the three status predicates plus focused test/evidence; session and create wrappers untouched |
-
-## Documentation decision
-
-No operator/API documentation change is needed: this restores documented list behavior for a healthy GLPI response without changing command syntax, output, configuration, or public contracts. This task scratchpad records delivery evidence.

-# Issue #808 — agent-send sender identity
-
-## Objective
-
-Fix cross-socket `agent-send.sh` preambles so replies route to the real sender rather than a destination-socket holder session.
-
-## Scope and acceptance criteria
-
-- Prefer exported `MOSAIC_AGENT_NAME` as the authoritative sender session name.
-- If it is unset, query the sender's local/default tmux socket for `#S` without destination `-L` arguments.
-- Preserve `?` when sender identity cannot be determined.
-- Do not alter destination socket dispatch.
-- Add red-first regressions for all three identity paths.
-
-## Plan
-
-1. Extend `agent-send.test.sh` with deterministic fake-tmux coverage.
-2. Run the test against the unpatched implementation and record RED evidence.
-3. Apply the minimal sender lookup fix only.
-4. Run the focused suite and repository quality gates.
-5. Commit, queue-guard, push, and open an author-only PR for independent review.
-
-## Constraints and risks
-
-- Worker lane is author-only: no self-review or merge.
-- `docs/TASKS.md` and mission state are orchestrator-owned and will not be modified.
-- Pre-existing runtime changes under `.mosaic/orchestrator/` are excluded from this work.
-- Budget: no explicit token cap; keep changes limited to the shell tool, sibling regression test, and this scratchpad.
-
-## Evidence
-
-- RED: `bash packages/mosaic/framework/tools/tmux/agent-send.test.sh` failed on the unpatched implementation with `PASS=12 FAIL=3`; it selected `destination-holder` instead of both `MOSAIC_AGENT_NAME=authoritative-agent` and local session `local-agent`. The genuinely unavailable sender case already exercised and preserved `?`.
-- GREEN: `bash packages/mosaic/framework/tools/tmux/agent-send.test.sh` passed with `PASS=15 FAIL=0`; coverage includes env authority, local/default tmux fallback across a destination `-L`, explicit rejection of the destination holder, and `?` fallback.
-- Syntax: `bash -n packages/mosaic/framework/tools/tmux/agent-send.sh packages/mosaic/framework/tools/tmux/agent-send.test.sh` passed.
-- Quality gates: `pnpm typecheck` (42/42 tasks), `pnpm lint` (23/23 tasks), and `pnpm format:check` all passed after installing the frozen lockfile dependencies. The first install attempt failed because pnpm's configured store pointed at `/root`; retrying with the existing user-owned store (`--store-dir /home/hermes/.local/share/pnpm/store`) succeeded without changing tracked dependency files.
-- Documentation: no public API or operator workflow changed; the source comment, regression-test contract, and this implementation record cover the internal bug fix.
-- Independent review: intentionally pending for the reviewer assigned by `mosaic-100`; this author-only lane will not self-review or merge.

-# Issue #824 — Mosaic skill CLI and Claude bridge auto-sync
-
-## Objective
-
-Deliver `mosaic skill register|unregister|list` plus install/upgrade reconciliation of every canonical `~/.config/mosaic/skills/*` entry into `~/.claude/skills/`, without clobbering runtime-owned files or directories.
-
-## Scope and constraints
-
-- Issue: mosaicstack/stack#824
-- Branch: `feat/824-mosaic-skill-cli`
-- M1 runtime: Claude Code only.
-- Pi/Codex parity is documentation-only; no non-Claude bridge implementation.
-- Do not author the downstream `mosaic-context-refresh` skill.
-- Workers do not modify `docs/TASKS.md`, merge, close #824, or touch `main`.
-- TDD is mandatory and red-first; filesystem tests use temporary directories only.
-- Budget: no explicit token cap supplied; use a focused single-worker implementation with no new dependencies.
-
-## Requirements mapping
-
-1. Register creates the canonical Claude symlink and is idempotent.
-2. Names are untrusted: reject empty/escaping/absolute/separator/`..`/leading-dash names before filesystem mutation, with clear CLI stderr and nonzero status.
-3. Register repairs only Mosaic-owned dangling symlinks and refuses foreign files, directories, and symlinks.
-4. Unregister removes only symlinks pointing inside the canonical Mosaic skills root and is idempotent when absent.
-5. List reports registered, dangling, foreign, and canonical-but-unregistered skills.
-6. Install and upgrade generically reconcile all canonical skills after framework sync/re-seed, continuing past foreign conflicts without clobbering them.
-7. User/developer documentation describes commands, status meanings, security boundaries, and Claude-only M1 scope.
-
-## Plan
-
-1. Add co-located failing Vitest coverage for all filesystem behaviors and auto-sync.
-2. Run the focused spec and record the expected RED failure.
-3. Commit the red contract as `test(#824): ...`.
-4. Implement the skill bridge and Commander command registration.
-5. Wire reconciliation into wizard finalize and `mosaic update` re-seed, preserving non-clobber behavior.
-6. Update canonical docs and sitemap if navigation changes.
-7. Run focused tests, package tests, typecheck, lint, and formatting.
-8. Commit implementation/docs as `feat(#824): ...`, queue-guard, push, open PR with `Closes #824.`, fire completion event, and notify the coordinator.
-
-## Progress
-
-- 2026-07-17: Loaded mission/delivery/TDD/documentation rails, issue #824, active mission state, and relevant installer/update paths.
-- 2026-07-17: Confirmed `mosaic update` invokes `framework/install.sh` with `MOSAIC_SYNC_ONLY=1`; that path exits before existing post-install skill linking, leaving newly present canonical skills unregistered.
-- 2026-07-17: Coordinator addendum classified the user-supplied skill name and runtime symlink target as a path-traversal/symlink-injection surface. Expanded the initial red contract to reject traversal before mutation, preserve every foreign entry, and unregister Mosaic-owned links only.
-- 2026-07-17: Implemented the Commander command group and secure generic bridge; wired wizard finalize and successful framework re-seed reconciliation; updated user/developer/installed/root docs and sitemap.
-- 2026-07-17: Focused, package-wide, repository baseline, temp-home situational, and independent review gates completed. Ready for scoped feature commit, queue guard, push, and PR handoff.
-
-## Tests and evidence
-
-### TDD evidence
-
-- RED environment attempt: `pnpm --filter @mosaicstack/mosaic exec vitest run src/commands/skill.spec.ts` initially could not locate Vitest because this fresh worktree had no dependencies.
-- Dependency setup: `pnpm install --frozen-lockfile --store-dir /home/hermes/.local/share/pnpm/store` succeeded. The explicit store was required because machine pnpm config incorrectly resolves the default store under `/root`.
-- RED behavior: focused Vitest failed with `Failed to load url ./skill.js ... Does the file exist?`, proving the bridge API was absent.
-- RED integration: finalize/update specs failed because no Claude links or `skillSync` result existed.
-- RED symlink injection: symlinked Claude/canonical root tests failed because the initial implementation followed ancestor links.
-- GREEN after review remediation: `skill.spec.ts` 36/36, `finalize-skills.spec.ts` 6/6, and `update-checker.reseed.spec.ts` 30/30.
-
-### Baseline gates
-
-- `pnpm --filter '@mosaicstack/mosaic...' run build` — pass (fresh-worktree dependency outputs built).
-- `pnpm --filter @mosaicstack/mosaic run typecheck` — pass.
-- `pnpm --filter @mosaicstack/mosaic run lint` — pass.
-- `pnpm --filter @mosaicstack/mosaic test` — pass: 69 files, 1,325 Vitest tests plus framework shell suite.
-- `pnpm typecheck` — pass: 42/42 Turbo tasks.
-- `pnpm lint` — pass: 23/23 Turbo tasks.
-- `pnpm format:check` — pass.
-
-### Situational evidence
-
-A built-CLI temp-home smoke test (no real `~/.claude` or Mosaic config touched) proved:
-
-- register creates the exact link and a second run reports `already registered`;
-- list reports registered and unregistered canonical skills;
-- `../../etc` exits 1 with `Invalid skill name` and creates no escaped path;
-- unregister removes the managed link and a second run reports `already unregistered`;
-- a fake successful framework re-seed generically registered both `added-after-setup` and `second-skill` from runtime directory enumeration.
-
-### Review evidence
-
-- Initial uncommitted Codex code/security review described name validation/clobber protection as strong; its only finding was the harness-owned, unrelated `.mosaic/orchestrator/session.lock`, which is excluded from all commits and the PR.
-- Exact branch review then identified two remediations: preserve successful framework re-seed status when bridge-wide reconciliation fails, and reject/escape control-character names to prevent terminal/log injection.
-- Both findings were reproduced red-first and remediated. A subsequent exact review identified one finalize failure-isolation blocker; a root-wide bridge error now warns and allows wizard doctor/summary/next-steps completion, with a red-first regression.
-- All remediations passed the full package and repository gates. Final exact-head review is rerun after amending the feature commit.
-
-### Acceptance mapping
-
-| Acceptance criterion | Evidence |
-| --- | --- |
-| register/unregister/list, idempotent | `skill.spec.ts` and built-CLI temp-home smoke |
-| traversal/symlink-injection protection | invalid-name matrix, foreign file/dir/link tests, symlinked-root tests |
-| list flags dangling and foreign entries | deterministic list status test |
-| install and upgrade auto-sync every canonical directory | finalize + framework re-seed integration specs; two-skill built-module smoke |
-| newly added skill becomes discoverable without manual link | `added-after-setup` auto-sync creates exact Claude link; Claude can rescan with `/reload-skills` or a new session |
-| Pi/Codex parity captured as scope note | user guide, developer guide, installed framework README |
-| documentation gate | root README, user guide, developer guide, framework README, sitemap |
-
-## Risks
-
-- Symlink replacement uses `lstat` semantics so dangling links are detectable without following them.
-- Link ownership is determined lexically against the canonical skills root, and existing symlink ancestors in either managed root are rejected before mutation.
-- Auto-sync continues across per-skill conflicts while never deleting real files/directories or foreign symlinks.
-- Claude Code discovers filesystem skills at session launch/reload boundaries; bridge creation makes a later `/reload-skills` or new session able to discover the skill, but cannot mutate an already-cached in-process registry by itself.
-- Pi does not need this Claude bridge because its Mosaic launcher can consume the canonical root. Codex lifecycle parity remains explicitly deferred.
-- No deployment surface is affected.
-
-## PR #826 review remediation
-
-- 2026-07-17: Exact-head RoR requested changes for two ownership bugs: installer pruning deleted foreign-name links under `MOSAIC_HOME` outside canonical skills, and unregister deleted a same-root link targeting a different skill. It also requested trailing-dot rejection and executable coverage support.
-- RED evidence: focused regression run failed 4 tests: register/unregister accepted `safe.`, misdirected unregister did not throw, and the install linker deleted the foreign-name link.
-- GREEN evidence: `skill.spec.ts` passes 43/43, including live and dangling foreign-name links in a temp HOME/MOSAIC_HOME and the misdirected unregister invariant.
-- Coverage: `vitest run src/commands/skill.spec.ts --coverage` passes configured 85% thresholds for `skill.ts`: 91.05% statements/lines, 86.27% branches, 95.23% functions.
-- Full gates: package build passed; package tests passed 69 files / 1,332 tests plus framework shell suite; repository typecheck 42/42, lint 23/23, and format check passed.

-
-- **Issue/card:** #758 / FCM-M2-001
-- **Branch/base:** `feat/758-generated-env-boundary` from `origin/main` `e9c4aa3e8b3780719cd5a43c0ef3f37fc70de666`
-- **Budget assumption:** 30K-card budget; implement only the deterministic generated/local environment boundary and its launch-chain/docs/tests.
-
-## Objective
-
-Replace the generic fleet agent `.env` authority/merge path with a deterministic roster-derived `<agent>.env.generated` projection and strict, data-only `<agent>.env.local`. The roster remains the desired-state authority. Reject bad input before the launcher creates a tmux session; never print sensitive or privileged-command values.
-
-## Scope and non-goals
-
-- In scope: deterministic render/write, strict generated/local parse rules, legacy `.env` disposition/quarantine, systemd/launcher boundary, permission/path checks, focused fail-closed tests, operator/reference documentation, USC interface evidence.
-- Excluded: roster CRUD/mutation, v2 roster schema changes, lifecycle/reconcile/apply behavior, migration/canary rollout, connectors, remote surfaces, live-fleet actions, and M2-002.
-
-## Plan
-
-1. Add red tests for generated-key shadowing, malformed/duplicate/unknown/command/sensitive input, no-value diagnostics, deterministic/idempotent projection, secure file modes, and legacy disposition.
-2. Implement a pure strict environment contract plus atomic projection/quarantine helper.
-3. Replace the generic `.env` writer/merge path and systemd reference with `.env.generated` + `.env.local` ownership.
-4. Make the shell launcher parse the files without `source`/`eval`, reject unsafe input before tmux creation, and construct only the roster-derived runtime command.
-5. Add operator/reference documentation with the requested USC M1 interface evidence and M2–M4 gate statement.
-6. Run focused/package/root gates and audit the USC interface packet. Per continuation scope, stop before review, commit, push, PR, or live mutation.
-
-## Initial evidence
-
-- No existing owner: target worktree path absent; no target local/remote branch; `pr-list.sh -s open` returned no open PRs.
-- M1 compiler/API/docs and executable disposition evidence are present at the assigned base.
-- Existing launch chain writes `fleet/agents/<agent>.env`, preserves arbitrary legacy lines via `mergeAgentEnv`, sources `MOSAIC_AGENT_COMMAND`, and executes it through `bash -c`; all are M2 remediation targets.
-- `~/.config/mosaic/guides/SECURITY.md` is absent. Read the available security-review role contract and the vault/secrets guide instead.
-
-## Verification log
-
-### Continuation (2026-07-14)
-
-- Preserved the inherited 14-file delta; no reset, stash, rebase, roster mutation, lifecycle action,
-  live-fleet action, commit, push, or PR action was performed.
-- Focused gates passed:
-  - `pnpm --dir packages/mosaic test -- src/fleet/generated-env-boundary.spec.ts` — 1 file, 10 tests passed.
-  - `bash packages/mosaic/framework/tools/fleet/test-start-agent-session.sh` — passed.

-  - `pnpm --dir packages/mosaic lint` — passed.
-  - `pnpm --dir packages/mosaic test` — 52 files, 752 tests passed.
-- `pnpm format:check` initially failed only for the new boundary reference and generated-boundary
-  TypeScript files; targeted Prettier normalization was applied. A final `pnpm format:check` passed.
-- USC packet audit: the M1 structural compiler is `parseRosterV2` with roster `version: 2`; the
-  semantic resolver is `validateRosterV2Semantics`; disposition artifacts retain `version: 1` fixture
-  evidence. `docs/TASKS.md` records M1-001 done, M1-002 in-progress, and M1-003 not-started; no
-  product release version is claimed. The packet now distinguishes these statuses from checkout
-  artifact presence and states the M2 → M3 → M4 downstream gates.
-
-## Review remediation (2026-07-14)
-
-- **Blocker 1 red-first:** Added a launcher reproducer with a `0777` `fleet/agents` parent and a private generated file. Before implementation, `bash packages/mosaic/framework/tools/fleet/test-start-agent-session.sh` failed: `FAIL: generated file under a world-writable parent was accepted`. The failure occurred after the launch path reached fake tmux, proving the parent was not validated.
-- **Blocker 2 red-first:** Added a `symlink()` projection-directory reproducer that preloads generated/local/quarantine/legacy target files and asserts no target mutation. Before implementation, `pnpm --dir packages/mosaic test -- src/fleet/generated-env-boundary.spec.ts` failed the new test because the existing writer followed the `agentEnvDir` symlink and parsed its target legacy input (`expected /unsafe-directory/i`, received `code=malformed-line`). The initial test-only missing `mkdir` import was corrected before recording this behavior failure.
-- **Blocker 3 red-first:** Added fresh/stale/absent native-heartbeat regression coverage. Before implementation, an isolated fake-tmux launcher reproducer with a fresh `<agent>.hb.native` marker failed `FAIL: fresh native heartbeat was overwritten`; the existing sidecar immediately replaced native `status=busy`/`model` content.
-- **Remediation result:** The launcher now rejects a group/world-accessible or symlinked `fleet/agents` parent before an environment read or tmux call. The projection writer uses `lstat` before chmod/write processing and rejects a symlinked directory without creating generated/local/quarantine files or deleting legacy input. The heartbeat sidecar defers to a fresh non-symlink native marker and falls back when stale/absent. Focused green evidence before independent review: `bash packages/mosaic/framework/tools/fleet/test-start-agent-session.sh` and `pnpm --dir packages/mosaic test -- src/fleet/generated-env-boundary.spec.ts` (11 tests) passed.
-- **Independent-review follow-up red-first:** Codex code review returned one blocker and security review one medium CWE-732 finding: the writer repaired an already `0777` directory with `chmod` before trusting its contents. Added a reproducer with a safe local file beneath an existing `0777` directory. Before the follow-up fix, `pnpm --dir packages/mosaic test -- src/fleet/generated-env-boundary.spec.ts` failed because the promise resolved and wrote `coder0.env.generated` instead of rejecting.
-- **Independent-review remediation:** Existing directories now pass non-following private-directory validation before any read or chmod; only a directory created in this call is normalized to `0700`. The fleet-add test fixture now creates its simulated trusted `fleet/agents` boundary at `0700`; this corrects fixture setup to match the new required contract rather than weakening the rejection assertion. Focused reruns passed: generated-boundary 12 tests, launcher boundary suite, and fleet suite 192 tests.
-- **Final verification before re-review:** Launcher + systemd suites passed; package suite passed (52 files, 754 tests); package lint/typecheck, root typecheck (42 tasks), format check, and diff check passed. The rerun code review still reports a tmux command-arity blocker, and the security rerun reports systemd `EnvironmentFile` pre-validation injection findings for both agent units. These were discovered after the specified three-remediation scope; no additional source changes were made. Independent review therefore remains `REQUEST CHANGES` despite the requested three fixes passing their behavioral suites.
-
-## Systemd pre-validation remediation (2026-07-14)
-
-- **Red-first:** Updated the fleet unit contract to reject any `EnvironmentFile=` projection preload, require a cleared bootstrap environment, and require a validated exact-stop path. Before implementation, `bash packages/mosaic/framework/systemd/user/test-fleet-units.sh` failed: `FAIL: agent units must not preload projections before strict parsing`.
-- **Red-first parser/stop coverage:** Added interaction-wrapper and exact-stop cases to the launcher boundary suite. Before implementation, `bash packages/mosaic/framework/tools/fleet/test-start-agent-session.sh` failed: `FAIL: interaction did not use shared strict parser first`, because the interaction wrapper consumed inherited environment before projection validation.
-- **Focused green:** Both unit templates now use `env -i` with fixed `HOME`, agent instance, and PATH; neither has `Environment=`/`EnvironmentFile=`. The interaction wrapper delegates to `start-agent-session.sh --interaction`, so strict generated/local parsing precedes pinned Pi profile checks. `--stop` reuses the strict generated parser before exact `=<agent>` socket/session termination. Passed: systemd unit suite, launcher boundary suite (including malformed interaction, pinned profile, and ambient-socket stop cases), and 210 focused TypeScript tests.
-- **Final verification:** `pnpm --dir packages/mosaic test` passed (52 files, 754 tests); package lint/typecheck, root typecheck (42 tasks), format/diff, and shell syntax checks passed. Security review passed with no findings. Code review repeated the previously refuted tmux argv concern and a pre-existing Claude trust-lock suggestion; per the assigned narrow follow-up, no tmux or unrelated trust-path change was made.
-
-## Risks and next review
-
-- This card is uncommitted and unreleased. The canonical tracker still records its dependencies as
-  M1-002 in progress and M1-003 not started; this continuation does not reinterpret those task states.
-- Final post-documentation checks passed: `pnpm --dir packages/mosaic typecheck`,
-  `pnpm --dir packages/mosaic lint`, `pnpm --dir packages/mosaic test` (52 files, 752 tests),
-  `pnpm typecheck` (42 Turbo tasks), and `pnpm format:check`.
-- Obtain independent code and security review of the complete delta next. Do not run commit, push,
-  PR, or live-fleet commands in this continuation.
-
-## Fresh-install directory remediation (2026-07-14)
-
-- **Objective:** Remediate only the fresh-install path where `installFleet` created `fleet/agents`
-  with host-umask permissions before the boundary writer correctly rejected it.
-- **Plan:** Add a real `fleet install --no-enable` integration reproducer; prove red; let the
-  existing boundary writer own directory creation; run focused and full gates. No commit, push,
-  PR, review disposition, or live-fleet action.
-- **Red evidence:** Before the one-line remediation,
-  `pnpm --dir packages/mosaic test -- src/commands/fleet.spec.ts` failed the new test with
-  `AgentEnvBoundaryError: code=unsafe-permissions` at `ensurePrivateProjectionDirectory`, after
-  `installFleet` pre-created the directory.
-- **Change:** Removed only the recursive `mkdir(activePaths.agentEnvDir)` in `installFleet`.
-  `writeAgentEnvironmentProjection` remains the sole creator and retains its existing `lstat`,
-  private-directory, symlink, and existing-unsafe-directory fail-closed checks.
-- **Focused green:** `pnpm --dir packages/mosaic test -- src/commands/fleet.spec.ts` — 193 tests
-  passed. The new integration executes a fresh `fleet install --no-enable`, asserts a real
-  non-symlink `0700` directory and a `0600` generated projection. Existing unsafe-directory
-  coverage remains in `generated-env-boundary.spec.ts` and asserts no chmod repair/no generated
-  file write.
-- **Full gates green:** generated-boundary 12 tests; launcher and systemd suites; package
-  typecheck/lint and 52 files / 755 tests; root typecheck (42 tasks), lint, format, diff check,
-  and root test (42 tasks) all passed.
-- **Independent review:** The complete inherited uncommitted delta still has Codex `REQUEST CHANGES`
-  findings outside this narrow fix (tmux command arity and Claude trust-lock regression), plus a
-  security-review medium finding on unvalidated writable ancestor directories. No out-of-scope
-  source changes were made.
-- **Risk:** The writer's existing create-then-validate sequence is relied on for the creation
-  boundary; a concurrent substitution causes fail-closed validation rather than repair. The
-  review findings above remain residual risks for the complete card delta.

-
-- **Issue:** #766
-- **Branch:** `fix/766-exact-fleet-comms`
-- **Worktree:** `/home/jarvis/src/stack-issue-766`
-- **Delivery boundary:** source/tests/docs only; no live tmux, session, or fleet actions; leave uncommitted for independent review.
-
-## Objective
-
-Replace inference-prone fleet onboarding guidance with one roster-resolved contract that gives Claude Code, Codex, OpenCode, and Pi the same authoritative local identity and exact executable command for every known peer.
-
-## Plan
-
-1. Add issue-specific normative requirements to `docs/PRD.md` before source changes; do not modify orchestrator-owned `docs/TASKS.md`.
-2. Extract the existing v1 roster parsing/normalization into one lightweight shared resolver used by both fleet commands and runtime comms composition.
-3. Write failing contract tests for explicit SSH-only cross-host targeting, global/default socket authority, authoritative identity, unknown-peer failure, no operational metavariables, and four-harness parity.
-4. Make source `TOOLS.md` non-operational and marker-versioned; prove fresh installation preserves that exact contract and composition detects a stale installed copy without rewriting it.
-5. Render a deterministic comms generation and document comparison/relaunch handling; never rewrite an active session.
-6. Run focused Vitest and shell exact-target tests, then package/repository typecheck, lint, format, test, and build gates as relevant.
-7. Reconstruct the exact uncommitted tree, including untracked files, for independent review and remediate findings without committing.
-
-## Contract decisions
-
-- `tmux.socket_name` is the one supported socket authority for every local fleet session. A per-agent `socket`, when present for compatibility, must equal that global value; independent per-agent sockets fail closed because the runtime does not provision them. A named socket renders `-L`, while the empty literal default renders no `-L`.
-- A peer is same-host only when its resolved host equals the current roster member's resolved host. Every host-omitted member resolves against the stable local fleet-host baseline, never against the viewer's explicit host. Same-host rows never render `-H`.
-- A cross-host row requires that peer's explicit roster `ssh`; absence is a contract error. Never substitute `host` as an SSH target.
-- The current member's explicit roster `host` wins; otherwise the local machine's short hostname is the baseline for host-omitted local members.
-- Unknown members/peers return a deterministic error listing exact known names and an exact self-scoped discovery command. No fuzzy session lookup.
-- Exact command fields are structurally constrained to safe targeting grammars and shell-rendered as individual arguments. Unsafe host/SSH/socket values fail roster normalization rather than entering executable guidance.
-- Existing installed `TOOLS.md` remains user-owned during ordinary keep-mode updates. Currency requires the expected source and installed marker/version plus bounded SHA-256 byte identity. Explicit `mosaic update --repair-tools` is the supported current-version recovery path: it makes a digest-qualified no-clobber backup, restores the contract and regular executable helper, and does not rewrite active context.
-- The v1 resolver preserves and validates `tmux`, `discord`, and `matrix` connector blocks in YAML and JSON; conflicting snake/camel aliases fail closed unless their values are identical.
-- JSON roster fallback occurs only when `roster.yaml` is absent. Keep-mode reseed preserves both formats, and relaunch discovery uses the same canonical resolver.
-- The helper is inspected without following symlinks and must be a regular executable file. Missing, directory, symlink, and non-executable installations fail closed with deterministic repair guidance.
-- Active contexts carry a deterministic comms generation. Operators compare it to `mosaic agent comms-block <exact-agent>` output; mismatch means stale and requires an explicit exact-agent relaunch.
-
-## Risks
-
-- Import cycles if runtime composition imports the command-heavy `fleet.ts`; mitigate with a lightweight shared roster module and re-export compatibility.
-- Existing schema prose allowed independent per-agent sockets even though runtime provisioning used one global socket; constrain compatibility declarations to the global value and preserve empty-global default behavior.
-- Remote inventory may be incomplete. Fail composition closed for an unreachable cross-host row rather than generating a guessed command.
-- `TOOLS.md` is user-seeded and intentionally preserved. Detect/report drift instead of overwriting custom content.
-
-## Planned evidence
-
-- `comms-onboarding.spec.ts`: resolver/renderer/failure/generation contracts.
-- `compose-contract.spec.ts`: identical authoritative comms section for all four harnesses and stale installed-contract reporting without mutation.
-- `file-adapter.test.ts`: source-to-fresh-install byte equality and preservation of customized installed `TOOLS.md`.

-- Repository quality gates and independent uncommitted-tree review.
-
-## Evidence log
-
-- Preflight collision scan: no issue-766 local/remote branch, worktree, or open PR collision before branch creation.
-- Isolated branch created from fetched `origin/main` at `4990905`; original checkout not edited.
-- One strict v1 resolver now serves fleet commands and communications composition; roster writes preserve `host`, `ssh`, and `socket`.
-- Exact renderer covers authoritative self identity, global/default socket authority, rejected independent sockets, stable hostless-peer resolution, same-host omission of `-H`, explicit-SSH-only cross-host rows, shell-safe argv rendering, deterministic generations, and fail-closed unknown/missing targets.
-- Real framework `defaults/TOOLS.md` is tested byte-equal through a fresh `FileConfigAdapter` install, the installed helper is executable, and the final Pi contract contains the same source contract plus exact generated command; separate parity coverage proves byte-equivalent comms sections for Claude Code, Codex, OpenCode, and Pi.
-- Second review remediation adds strict connector/alias coverage, full-semantic generation coverage, ENOENT-only fallback, no-follow helper validation, unconditional current-version repair, digest-qualified no-clobber backups, and marker/version-gated currency.
-- The helper, roster, installed TOOLS, and framework source files are read with canonical containment, every existing ancestor and target rejected if symlinked, `O_NOFOLLOW` descriptor reads, inode stability checks, and effective-identity execute access. Read-only TOOLS status treats source/installed symlinks as unavailable without following or rewriting them.
-- Explicit repair validates both bundled inputs before destination creation, stages backup/TOOLS/helper plus exact-mode rollback files before any persistent file commit, revalidates destination identity at each commit boundary, installs the digest backup without clobber, and removes or exactly rolls back every committed output on injected failure. `changed: false` is returned only after full cleanup; cleanup/rollback failure is reported as `changed: true`.
-- Connector schema and runtime normalization require kind-matching settings and reject inactive connector blocks. Keep-mode installers preserve only exact `roster.yaml`, `roster.json`, `agents/`, and `run/` paths while refreshing framework `roster.schema.json`; shell evidence covers byte preservation and schema refresh.
-- Solo contracts render normalized role/class plus explicit no-peer/no-remote authority boundaries; composed-contract evidence keeps role Mandate/Boundaries before Fleet Comms.
-- Operational documentation and CLI metavariable now use `mosaic agent comms-block <exact-member>`; historical issue-633 scratchpad text remains historical.
-- The latest independent review rejected synthetic tree `556ae4ea04f2715a4e9d381f3cafaf4c8b991b2e` on three mandatory findings: installed `TOOLS.md` could be read through target/ancestor symlinks before unsafe status was reported; ambient class/tool-policy state could split identity authority from the canonical roster member; and the connector schema admitted empty or whitespace-only Discord/Matrix strings rejected by runtime parsing.
-- Red-first reproduction proved all three findings with 20 failures and 79 passes. Remediation routes installed `TOOLS.md` through the bounded secure regular-file reader before composition, resolves one exact canonical fleet identity for persona/tool policy/normalized class/Fleet Comms, rejects canonicalized ambient class mismatches, canonicalizes compatibility classes during roster parsing, and aligns parser/schema non-whitespace requirements.
-- Four-runtime coverage proves unsafe target and ancestor symlink content is omitted without mutation, while Claude Code, Codex, OpenCode, and Pi all project the same canonical member authority. Connector parser/schema coverage includes empty and whitespace-only Discord `channel_id` and Matrix `homeserver_url`, `user_id`, and `room_id` values.
-- Remediated focused gates passed: 99/99 across the two finding-focused suites plus connector schema regression PASS; the six changed-suite matrix passed 341/341; secure-file/transaction coverage remains green, including 28/28 transactional repair tests; installer migration passed 21/21.
-- Mosaic package suite passed 906/906. Shell/runtime regressions passed: `agent-send.test.sh` `PASS=11 FAIL=0`; named-socket isolation; matrix/tmux transport 12/12 (Matrix 5/5, tmux 7/7).
-- Final repository gates passed: format check; typecheck 42/42 tasks; lint 23/23; tests 42/42 tasks (Mosaic 906/906, gateway 628 passed/12 skipped); build 23/23.
-- A subsequent immutable review of tree `aa6414123643a504145fce6ac1d66f0b535feb5e` found one roster-authority blocker: a canonical member with omitted `tool_policy` inherited ambient `MOSAIC_AGENT_TOOL_POLICY`. Red-first four-runtime coverage failed 4/39 specifically on the leaked operator-interaction policy. Composition now branches on canonical membership: fleet launches use only `canonicalMember.toolPolicy` (including canonical absence), while genuinely non-fleet launches retain ambient fallback.
-- Final remediated gates passed: four-runtime regression 39/39; six changed-suite matrix 345/345; connector schema regression PASS; Mosaic package 910/910; installer migration 21/21; `agent-send.test.sh` 11/11; named-socket isolation PASS; Matrix/tmux transport 12/12; repository format PASS; typecheck 42/42 tasks; lint 23/23 tasks; tests 42/42 tasks; build 23/23 tasks.
-- No live tmux/session/fleet mutation, commit, push, PR mutation, issue mutation, context mutation, or reviewer launch performed.
-- Exact synthetic-tree reconstruction and frozen evidence are included in the coordinator handoff.
-- Sole-remediation preflight reverified the clean committed checkout at head `0dc47cac92c93a3ffd39ba9dd6685ac4165f6361`, tree `538de6ccce1f8c44ba288a7493286e63a3413e75`, branch `fix/766-exact-fleet-comms`; issue and PR state were read only through Mosaic wrappers.
-- Deterministic red-first ancestor substitution swapped validated `root/tools` for an external symlink immediately after `lstat`; current head returned `external marker` (`1 failed, 4 passed`) before implementation.
-- Secure reads now hold `/` and every root/descendant directory descriptor, traverse appended components through Linux `/proc/self/fd` with `O_DIRECTORY|O_NOFOLLOW`, and read plus effective-identity execute-check the same final descriptor. Non-Linux or unavailable proc-fd capability fails closed; stable errors redact managed paths while retaining Node `code` compatibility for missing/non-executable repair behavior.
-- Added deterministic root-selection, descendant-ancestor, and final-target substitution coverage. All return trusted descriptor-bound bytes after rename/symlink replacement; the race suite passed 50/50 repeated runs.
-- Isolated CLI verification drove `mosaic agent --mosaic-home <fixture> comms-block self` while repeatedly swapping `fleet/` with an external symlink: `trusted=2 fail_closed=10 external_marker=0`; a persistent symlink ancestor exited 1 with a redacted unsafe-ancestor error. No live fleet state was used or mutated.
-- Remediation gates: focused secure-file/comms/launch/tmux/Matrix `110/110`; full `@mosaicstack/mosaic` `914/914`; package and repository typecheck pass (`42/42` repository tasks); package and repository lint pass (`23/23` repository tasks); repository format check and `git diff --check` pass.
-- Independent review found one production hardening blocker (nonblocking final open), one redacted-error blocker, and a deterministic ancestor-test gap. Remediation added `O_NONBLOCK`, normalized execute errors while preserving errno, proved the ancestor hook fires, and added final-target substitution coverage; post-remediation review evidence is clean on the production invariant.

-# ms-792 — Fleet roster error handling and installer heading
-
-## Objective
-
-Make expected missing or malformed fleet roster configuration fail with an actionable message and nonzero exit instead of a raw Node stack trace. Ensure the installer preserves the `@mosaicstack/mosaic` heading.
-
-## Plan
-
-1. Add failing coverage for missing and malformed roster input.
-2. Centralize roster-file read and parse error translation; add the CLI async error boundary.
-3. Sweep fleet command read paths that bypass the roster loader.
-4. Replace the installer heading output with format-safe rendering and test it.
-5. Run focused and repository quality checks; request independent review.
-
-## Progress
-
-- 2026-07-16: Confirmed issue #792 and branch base `9745bc3f`.
-- 2026-07-16: Installed locked workspace dependencies using a worktree-local pnpm store; no `.mosaic/` files were changed intentionally.
-- 2026-07-16: Added a shared roster read/parse guard and routed v1 fleet commands plus v1/v2 selection through Commander’s actionable nonzero error path. V2 command modules already return structured nonzero JSON errors for their guarded reads.
-- 2026-07-16: Replaced installer heading `echo` with format-safe `printf`; added a regression check for the scoped package heading.
-- 2026-07-16: Rebuilt CLI and manually verified `fleet ps` with no roster prints the initialization hint, exits 1, and has no stack trace.
-- 2026-07-17: Rebased #818 onto `origin/main` at `9ddc6fbd` (#791 PR3). The added `fleet regen` command had a canonical roster read in its sibling module; it now uses the same missing-roster guard and Commander exit path. Internal NORTH_STAR, preset, and post-write invariant reads remain intentionally unguarded.
-- 2026-07-17: RoR found that semantically invalid v1 documents still escaped as plain `Error` values. `normalizeFleetRosterV1` now preserves each validation message while converting it to `FleetRosterConfigurationError`, so its command callers use the actionable nonzero Commander path.
-
-## Verification
-
-- `pnpm --filter @mosaicstack/mosaic test` — PASS (61 files, 1,046 tests; executed outside sandbox because CLI smoke tests spawn Node)
-- `pnpm typecheck` — PASS
-- `pnpm lint` — PASS
-- `pnpm format:check` — PASS
-- `pnpm --filter @mosaicstack/mosaic exec vitest run src/commands/fleet.spec.ts src/commands/install-heading.spec.ts` — PASS (209 tests)
-- `pnpm --filter @mosaicstack/mosaic exec vitest run src/commands/fleet-regen-command.spec.ts` — PASS (27 tests, including missing canonical roster)
-- `pnpm --filter @mosaicstack/mosaic exec vitest run src/commands/fleet.spec.ts -t "semantically invalid v1 roster"` — RED then PASS; verifies duplicate agent names are reported as `fleet.roster` exit 1 without a stack trace.
-- Instrumented Vitest coverage is unavailable because `@vitest/coverage-v8` is not declared in this repository. Each branch added in the roster guard has direct unit coverage.

-## Risks / blockers
-
-- Dependency installation is required before executing Vitest, TypeScript, lint, and formatting gates.

-mosaic claude            # Launch Claude Code with Mosaic injection
-mosaic yolo claude       # …with --dangerously-skip-permissions
-mosaic codex | opencode | pi
-```
-
-### `mosaic claudex` (EXPERIMENTAL)
-
-Runs GPT models **inside the Claude Code harness** by pointing Claude Code at a
-local [`claude-code-proxy`](https://github.com/raine/claude-code-proxy) that
-translates the Anthropic Messages API to a ChatGPT-subscription (Codex OAuth)
-backend. This is **not Anthropic Claude** — model behavior, tool use, and output
-quality may differ. Intended for evaluation, not production delivery.
-
-```bash
-mosaic claudex           # launch (prompts through the proxy readiness gate)
-mosaic yolo claudex      # …with --dangerously-skip-permissions
-mosaic claudex --print "hello"   # trailing args are forwarded to Claude Code
-```
-
-**Prerequisite:** the `claude-code-proxy` binary must be installed and
-authenticated (`claude-code-proxy codex auth …`). `mosaic claudex` runs a
-preflight that verifies the binary, the OAuth state (triggering a device re-auth
-if needed), and a trusted local listener before launching; it **fails closed**
-if the proxy cannot be brought up with a verified identity.
-
-**Isolation (never touches your real Claude state).** claudex always launches
-against an isolated `CLAUDE_CONFIG_DIR` (default `~/.config/mosaic/claudex/home`).
-The ambient `CLAUDE_CONFIG_DIR` is deliberately ignored, and a guard proves the
-resolved dir can never be — or live under — the real `~/.claude`. A claudex
-session therefore cannot mutate your normal Claude Code config.
-
-**No token leakage.** claudex never reads the proxy's credential file. Claude
-Code is handed only `ANTHROPIC_AUTH_TOKEN=unused` pointed at the loopback proxy;
-the entire credential-bearing env family (`ANTHROPIC_*`, `AWS_*`, `GOOGLE_CLOUD_*`,
-`GOOGLE_APPLICATION_CREDENTIALS`, `*_TOKEN`, `*_KEY`, `*_SECRET`, …) is stripped
-from the composed environment. The Bedrock/Vertex routing switches
-(`CLAUDE_CODE_USE_BEDROCK`, `CLAUDE_CODE_USE_VERTEX`, and the `_SKIP_*_AUTH`
-pair) are force-removed regardless of value — otherwise their mere presence
-would route Claude Code to the real Anthropic API via AWS/GCP and bypass the
-proxy. The proxy holds the real OAuth credential.
-
-**Model tiers (override via env).**
-
-| Tier                  | Env var                      | Default        |
-| --------------------- | ---------------------------- | -------------- |
-| primary (opus/sonnet) | `ANTHROPIC_MODEL`            | `gpt-5.6-sol`  |
-| small/fast (haiku)    | `ANTHROPIC_SMALL_FAST_MODEL` | `gpt-5.6-luna` |
-
-Operator-provided values win over the defaults. Additional overrides:
-`MOSAIC_CLAUDEX_CONFIG_DIR` (isolated config dir), `ANTHROPIC_BASE_URL` (proxy
-endpoint).

 ## Universal Skills
