-# Authenticated external lease broker protocol
-
-The compaction-refresh lease broker is a Linux-only, newline-framed JSON protocol over a Unix stream socket. It is runtime-neutral; M1 consumers are limited to Claude and Pi. This is an internal process boundary, not an HTTP API, so it is intentionally absent from OpenAPI.
-
-The broker, never the caller, obtains `(pid, uid, gid)` from kernel `SO_PEERCRED`. It correlates the PID with `/proc/<pid>/stat` field 22 (`starttime`) and mints `session_id` on `register_anchor`. Presence of `session_id` in that request is refused even when its value is `null` or empty. Later requests must originate from the anchor or a descendant. The broker walks parent PIDs to the `(pid,starttime)` anchor and then rereads every walked PID's starttime before accepting the chain.
-
-## Request and response boundary
-
-Each connection carries exactly one UTF-8 JSON object followed by one newline, capped at 64 KiB. The protocol deliberately uses EOF to prove that there is exactly one frame: immediately after writing the newline, the client **MUST half-close its write side** with `shutdown(SHUT_WR)` (or Node `socket.end()`) before awaiting the response. A client that writes a newline but leaves its write side open receives no successful response; the broker's one-second connection deadline fails closed. Malformed, unterminated, multiple (including a delayed second frame), or oversized frames fail closed. Responses are one JSON object and one newline. Success has `{"ok":true,...}`; refusal has `{"ok":false,"code":"TYPED_CODE"}`. Requests are:
-
-- `register_anchor`: `action`, non-negative `runtime_generation`; no `session_id` field.
-- `authenticate`: `action`, broker-minted `session_id`, non-negative `runtime_generation`.
-- `mint_token`: authenticated identity plus `binding` containing exactly `compaction_epoch`, `request_epoch`, `h_source`, `h_payload`, and `schema_version`.
-- `consume_token`: authenticated identity plus `token`.
-- `begin_verification`: authenticated identity, runtime (`claude` or `pi`), cycle `binding`, and a TTL no greater than 300 seconds. The broker revokes existing authority first, enters `PENDING_VERIFICATION`, and returns a single-use promotion token.
-- `promote_lease`: authenticated identity plus the exact pending promotion token. The broker commits token consumption before making `VERIFIED` visible.
-- `revoke_lease`: authenticated observer signal; deletes pending tokens and makes the session `UNVERIFIED` immediately.
-- `authorize_tool`: authenticated identity, runtime, and exact runtime-reported tool name. The broker returns an explicit allow/deny decision from the whole-class policy and current lease.
-
-A higher generation for the same anchor atomically replaces the stored incarnation and deletes all prior tokens and lease authority for that session. A lower generation is stale. Tokens are 256-bit values from the operating-system cryptographic RNG and are single use. At most 256 pending tokens may be persisted; another mint fails with `TOKEN_CAPACITY` before mutation. Successful consumption deletes the token, while a replay still fails with `TOKEN_REPLAY`. Live v1 token records retain the existing `consumed: false` schema.

-VERIFIED leases are volatile and monotonic-time bounded: broker restart, generation change, explicit observer revocation, or expiry returns the session to `UNVERIFIED`. `begin_verification` always revokes before minting a new prerequisite. `promote_lease` is valid only from the matching pending cycle; persistence failure rolls token and lease state back, while post-rename durability uncertainty terminates the broker. The WI-1 token is the atomic promotion prerequisite substrate. A later receipt implementation must satisfy that prerequisite but cannot replace the mechanical mutator gate as safety authority.
-
-State replacement serializes and enforces the 4 MiB maximum before opening a temporary file, then uses a mode-`0600` temporary file, `fsync`, atomic rename, and parent-directory `fsync`. Every broker mutation snapshots the prior v1 state. A commit failure before rename restores that snapshot and leaves durable state unchanged. A failure after rename makes durability uncertain, so the store is poisoned without rolling memory back and the daemon terminates rather than serving with divergent state. Existing state is opened without following symlinks, must be a bounded regular file at mode `0600`, and is fully schema- and invariant-validated before use. Persisted tokens must be unconsumed, match their session's current generation, and remain within the 256-token cap. Session identity is uniquely keyed by `(anchor_pid,anchor_starttime)`; duplicate logical sessions for one anchor refuse startup. State integrity or mode failures refuse startup. The daemon does not log session IDs or tokens.

-# WI-1 lease broker security notes
-
-- Trusted identity comes only from Linux `SO_PEERCRED` plus `/proc` starttime, never request identity fields.
-- Descendant authorization is anchored to `(pid,starttime)` and uses a complete second starttime pass to fail closed on disappearance or PID-reuse races.
-- Runtime generations are monotonic per anchor; a bump revokes prior-incarnation tokens before persistence commits.
-- Session IDs and cycle tokens use the OS cryptographic RNG. `Math.random` and model output are not token sources.
-- Framing and persistence failures fail closed. Sensitive tokens are not logged.
-- Built-in `0700`/`0600` filesystem modes provide same-principal hardening only, not socket authenticity against the same UID. WI-1 provides no distinct-principal isolation. That stronger deployment requires an external protected proxy, ACL, or service boundary, and the boundary must preserve authenticated client identity for the broker's `SO_PEERCRED` and ancestry authorization rather than substituting a shared proxy identity.
-- WI-2 whole-class authorization denies every consequential, unknown, and custom tool while UNVERIFIED; it does not inspect shell strings or trust wrapper selection. First-class Claude/Pi, both Claudex dispatch modes, PRDY, QA remediation, coord, orchestrator, and fleet starts converge on broker register-before-exec; Claudex additionally installs the mandatory all-tools hook inside its preserved isolated config and fails closed on unsafe settings.
-- The permanent `check-runtime-launches.py` suite/CI guard scans production source for direct literal, absolute-path, process-API, command-array, and dynamic Claude/Pi launches. It has no bypass allowlist: an unrecognized launch form fails CI until routed through the common boundary.
-- WI-2 promotion consumes a WI-1 cycle token before VERIFIED becomes visible. Observer revocation, runtime-generation replacement, broker restart, and monotonic TTL expiry remove authority.
-- Receipt observation, payload construction, compaction observers, and constrained recovery implementation remain later surfaces. A receipt can become a promotion prerequisite but is never the safety mechanism.
-
-Coordinator security review must rerun the real socket/peercred and mutator-gate acceptance suites on an unrestricted Linux runner and obtain the mandated independent Opus-SECREV review before integration.

-# Whole mutator-class lease gate
-
-WI-2 adds the framework-native authorization boundary for Claude (including the supported Claudex overlay) and Pi. Every runtime-reported tool name reaches the lease broker before execution. The gate classifies capabilities by the whole tool class; it never parses a Bash command to decide whether that particular string looks read-only.
-
-## Default-deny policy
-
-While a session is not VERIFIED, only these exact classes are allowed:
-
-- Claude: `Read`, `Grep`, `Glob`, `Ls`, `Find`
-- Pi: `read`, `grep`, `find`, `ls`
-- Both runtimes: the fixed `mosaic_context_recover` primitive
-
-Every other built-in, unknown tool, and custom/MCP tool is consequential by default and is denied. This includes Claude `Bash`, `Edit`, `Write`, and `NotebookEdit`, plus Pi `bash`, `edit`, and `write`. A compromised model therefore cannot bypass Mosaic wrappers by selecting raw `git`, `curl`, `kubectl`, provider, deployment, or filesystem commands inside a generic mutator—the generic mutator itself is blocked before its input executes.
-
-## Broker-owned transition order
-
-The authenticated broker is the sole lease writer:
-
-1. `begin_verification` revokes existing authority and pending tokens first, then records `PENDING_VERIFICATION` and mints one WI-1 single-use promotion token bound to the exact cycle.
-2. `promote_lease` accepts only that session/generation/binding/token combination.
-3. Token consumption commits before the volatile lease becomes VERIFIED. Promotion is last and cannot be reached directly from UNVERIFIED.
-4. `revoke_lease`, a runtime-generation increase, broker restart, or monotonic expiry removes mutator authority.
-
-The initial TTL is capped at the ratified 300-second maximum. A caller may request a shorter positive TTL but cannot lengthen the maximum. Dual compaction-hook miss within an unexpired lease remains the ratified bounded T-A residual; once either observer revokes or TTL expires, the next consequential tool is denied.
-
-A receipt is only a future promotion prerequisite. It is not an obedience, residency, or safety proof and never replaces this mechanical gate.
-
-## Runtime adapters
-
-`launch-runtime.py` registers itself with the broker and then `exec`s Claude or Pi so PID/starttime remain the authenticated parent anchor. It exports only the broker-minted session ID and current generation to descendants.
-
-- Claude installs `mutator-gate.py` as an all-tools (`.*`) `PreToolUse` hook.
-- `mosaic claudex` and `mosaic yolo claudex` preserve their isolated `CLAUDE_CONFIG_DIR`, merge the mandatory hook into that isolated `settings.json`, and use the same register-before-exec launcher. Malformed or symlinked isolated settings deny launch.
-- Pi invokes the same executable from its `tool_call` handler.
-
-The executable submits the runtime's actual tool name to `authorize_tool`. Missing identity, malformed input/reply, timeout, broker unavailability, or denial exits with status 2 and blocks fail-closed.
-
-## Runtime-launch choke-point and permanent guard
-
-Every repository-owned Claude/Pi launch entry converges on `launch-runtime.py`, either directly or through `mosaic` → `execLeaseGatedRuntime`. PRDY init/update and QA remediation invoke the wrapper directly so their existing prompts, dangerous-permission behavior, working directory, and environment survive without skipping broker registration. The raw Claude `--dangerously-skip-permissions` primitive is owned only by `launch-runtime.py`; callers request semantic `--dangerous` mode, and the wrapper validates Claude before injecting the primitive. `@mosaicstack/coord` rewrites direct Claude commands to `mosaic claude` and rejects unknown custom Claude launchers.
-
-`check-runtime-launches.py` is the permanent completeness guard. It scans production shell, TypeScript/JavaScript, Python, and data launch definitions under `packages/`, `apps/`, `plugins/`, and `tools/`; direct literal, absolute-path, process-API, dynamic, command-substitution, `eval`, and variable-execution runtime launches fail. Shell comments are stripped with quote awareness, wrapper prefixes are tokenized with `shlex`, and only an invocation in command position with `--runtime` before the command separator is gated. Literal and tracked-variable command tokens use one terminal resolver after any nesting of `exec`, `command`, `nohup`, or `env` plus assignments. A direct command always wins over an inert marker on the same line. Independently, the raw dangerous primitive anywhere outside the choke-point is RED.
-
-The command parser is a best-effort CI defense, not a complete shell interpreter. Alias/function redefinition, sourced commands, generated scripts, and encoded pipelines are intentionally residual rather than an invitation to chase an unbounded shell language. Two runtime controls backstop that residual surface: primitive ownership rejects a dangerous launch even when command identity is alias-indirected, and Claude's global `.*` `PreToolUse` hook invokes the broker gate for non-dangerous launches. Without `MOSAIC_LEASE_SESSION_ID`, representative read, mutator, and custom/MCP tools all fail closed with `GATE_UNAVAILABLE`. Hook absence or replacement remains in the documented T-C boundary.
-
-### Parser stopping criterion
-
-- **A — realistic parser matrix:** comments, inert strings/assignments, heredocs, continuations, chained commands, command substitution, `eval`, bare tracked variables, and quoted/unquoted tracked variables behind `exec`, `command`, `nohup`, or `env` are permanent RED regressions. Prefix-variable forms are covered in both multiline and same-line assignment shapes.
-- **B — residual backstops:** a dangerous alias-indirected launch is RED solely through primitive anchoring; a parser-missed non-dangerous alias launch is paired with an acceptance test proving the global all-tools hook denies every representative tool class as `GATE_UNAVAILABLE` without a lease.
-- **C — independent fresh review:** the parser class is considered complete only when reviewers find no new non-overlapping realistic evasion on the exact head. A and B are repository evidence; C is supplied by the fresh review round.
-
-All three layers are load-bearing and complementary. The guard is mandatory in `@mosaicstack/mosaic`'s test script, so root CI fails on a future realistic bypass. Real-socket tests separately prove PRDY init/update and QA receive broker sessions and deny an unverified mutator.
-
-The live inventory is emitted by:
-
-```bash
-python3 packages/mosaic/framework/tools/lease-broker/check-runtime-launches.py --root . --json
-```
-
-| Production launch family                               | Gated entries |

-
-## Assurance boundary
-
-This closes T-A after an observer fires or lease expiry and T-B for in-runtime tool calls. Hook/extension absence, a runtime executing outside the gated launcher, ptrace/same-UID broker replacement, and other fully rotted behavior remain T-C. Server-side branch protection and required PR review/CI remain the irreducible line for protected repository mutations.

-
-## 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

+# Fleet Configuration Management
+
+This book documents the local roster-v2 desired-state control plane delivered under issue #758. The normative requirements are the [FCM section of the repository PRD](../PRD.md#fleet-declarative-configuration-management-workstream-fcm-758), not the older fleet-suite or observability planning pages.
+
+## Authority boundary
+
+<MOSAIC_HOME>/fleet/roster.yaml is the sole writable desired-state authority for local fleet membership, launch policy, and persisted lifecycle. Generated environment files, systemd enablement, tmux sessions, heartbeat files, and status output are derived or observed. Rebuild projections from the roster; never edit them as desired state.
+
+This control plane is local tmux/systemd only. Remote/SSH entries and connectors are inventory, not reconciliation targets. Arbitrary commands, channels, secret references, gateway catalog convergence, and UI configuration storage are outside this workstream. `mos-comms` is temporary transport glue, not permanent fleet architecture.
+
+## Choose the right workflow
+
+1. **Need to inspect intent?** Read the roster and use mosaic fleet get; see [desired versus observed state](concepts/desired-vs-observed-state.md).
+2. **Need to inspect reality?** Use `status` or `doctor`; use `verify` for a strict non-zero drift/ownership gate. These commands do not repair anything.
+3. **Need to change membership or persisted policy?** Use generation-guarded `plan`, `create`, `update`, or `delete`; see [safe CRUD](how-to/create-update-delete-agent.md).
+4. **Need a one-time runtime action?** Use `start`, `stop`, or `restart`. These do not change persisted desired state.
+5. **Need convergence?** Review apply --dry-run, resolve blockers, then use `apply` with the same current generation; see [reconcile and recover](operations/reconcile-and-recover.md).
+6. **Need v1 migration evidence?** Use preview only. Cutover, canary, and rollback remain held for FCM-M4-002.
+7. **Need the gateway-backed agent catalog?** That is the separate mosaic agent surface, not local fleet desired state.

+# Desired, Derived, and Observed Fleet State
+
+## One writable authority
+
+The canonical local v2 roster at <MOSAIC_HOME>/fleet/roster.yaml is desired state. Membership, stable identity, class, runtime/provider/model selection, launch policy, enablement, and persisted `running`/`stopped` intent are written only through generation-guarded roster mutations.
+
+Derived projections are reproducible consequences of that authority:
+
+- <name>.env.generated;
+- exact roster-named tmux sessions on the configured socket after reconciliation;
+- systemd service targets managed by installation/reconciliation.
+
+Current systemd unit enablement is not yet lifecycle-conformant at boot: installation can enable every
+agent unit, and the launcher projection does not carry `enabled` or `desired_state`. Therefore reboot
+preservation for stopped/disabled agents remains an FCM-M3-002 acceptance hold, not a guaranteed
+projection behavior.
+
+Observed evidence available to current roster-v2 status commands includes systemd active state, tmux
+presence, holder ownership, and unmanaged sessions. Heartbeat files are observational in the wider fleet,
+but roster-v2 `status`, `doctor`, and `verify` do not currently read them. Observation never writes back
+to the roster.
+
+## Generation and ownership
+
+`generation` is a positive integer concurrency fence. A mutating request must provide the current value. Successful changed CRUD increments it exactly once; stale or concurrent writers fail before mutation. Apply/reconcile rereads the canonical roster under a private exclusive lock and uses only that generation and content for effects.
+
+Ownership is exact, never fuzzy. Reconciliation is limited to roster names, the configured socket, the exact holder session, a private installation identity, and private managed paths. An ownership mismatch, unmanaged session, unsafe path, stale generation, or ambiguous lock fails closed.
+
+## Drift decisions
+
+| Observation                              | Interpretation           | Safe response                                                          |
+| ---------------------------------------- | ------------------------ | ---------------------------------------------------------------------- |
+| Generated file differs or is missing     | Derived projection drift | Review apply --dry-run; regenerate from the roster.                    |
+| Desired `running`, exact session missing | `missing-session`        | Diagnose ownership/runtime, then reconcile if safe.                    |

+Tess and Ultron are conventional instance/display names only. They are not products, required machine identities, role aliases, or authority-bearing classes. A configurable interaction instance uses class: interaction; a configurable validation instance uses class: validator. Any stable name and alias satisfying the structural contract may be used.
+
+Class aliases are deliberately narrow: implementer → code, reviewer → review, and operator-interaction → interaction. No runtime, provider, model, persona prose, or instance name changes this mapping. See [role classes](../reference/role-classes.md) and the [validated generic example](../examples/roster-v2.yaml).
+
+Roster v2 is local-only. It contains no host/SSH placement, connector, channel, secret-reference, arbitrary-command, per-agent socket, or gateway mapping fields. Those concerns require separate requirements and threat models.

+A lease is capacity authorization from an orchestrator, not ownership. It must identify a bounded task or period and does not alter the leased agent's roster identity, role contract, credentials, authority, or persisted lifecycle. Expiry/revocation returns capacity; it does not rewrite the roster.
+
+Semantic validation rejects protected class/tool-policy mismatch in either direction. An instance named Ultron with class: validator remains validation-only. An instance named Tess with class: interaction remains request/status-only. Renaming either instance changes no authority.

+# Configure an Interaction Instance
+
+An interaction instance is a configurable local roster member with canonical class: interaction and matching tool_policy: interaction. “Tess” may be used as a display alias, but neither that alias nor the stable name is required or authority-bearing.
+
+Use the [validated generic roster](../examples/roster-v2.yaml) as the safe shape. Choose a unique stable `name`, any descriptive `alias`, a supported declared runtime, explicit provider/model/reasoning, and a safe work directory. Start with:
+
+```yaml
+name: interaction-example
+alias: Interaction Example
+class: interaction
+tool_policy: interaction
+lifecycle:
+  enabled: true
+  desired_state: stopped
+```
+
+Plan the complete agent payload with the current roster generation, then create it without `--persisted-start`. Creation defaults to enabled/stopped and performs no runtime action. Review the resulting roster and projection plan before any later lifecycle decision.
+
+The interaction class is request/status only. It cannot orchestrate, issue leases, mutate the roster/configuration, grant credentials, certify validation, approve landing, or merge. Connector and channel configuration are outside roster v2; do not add connector, channel, secret, command, remote-host, or gateway fields.

 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.

-`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).
+`get` is the read/show operation for one v2 agent. Full roster parsing and semantic validation occur on every v2 mutation/reconcile path; there is no separate mutable “config store.” The executable JSON Schema and validated example provide offline structural evidence. The PRD requires an explicit programmatic mosaic fleet validate operation, but the current CLI does not expose one; do not substitute another command or claim that requirement is delivered. This remains an implementation gap for #758.
 
-`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.
+## JSON and exit behavior
 
-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.
+Roster-v2 CRUD and reconciler precondition failures emit { "error": { "code": "..." } } and exit non-zero. Migration preview has its own result envelope: a non-ready preview emits { "status": "blocked", "blockers": [...] } and exits non-zero rather than using the CRUD/reconciler error object. Use both exit status and command-specific state fields. A partial reconciliation result distinguishes `authoritativeRoster`, `projections`, `lifecycle`, `recovery`, and optional `cleanup`; it never claims automatic rollback. `verify` exits non-zero for drift, ownership failure, or unmanaged sessions. Sensitive legacy values, credentials, and rejected command text are never printed.
 
-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.
+## Compatibility and scope
+
+Roster-v1 initialization, provisioning, profiles/personas, and historical fleet add/remove remain compatibility surfaces, not roster-v2 CRUD aliases. New v2 automation should use the table above. migrate-v1 preview writes nothing and has no cutover, canary, or rollback option.
+
+mosaic agent is a separate catalog/transport surface; it does not own <MOSAIC_HOME>/fleet/roster.yaml desired state. Remote/SSH reconciliation, connector mutation, arbitrary commands/channels, secret references, and gateway convergence are rejected or outside scope.

-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.
+Explicit apply/reconcile never starts a stopped roster agent. Direct lifecycle commands are explicit one-shot actions and do not persist intent. The current update operation preserves `existing.lifecycle`; there is no delivered generation-guarded CRUD operation for changing durable lifecycle after creation. Reboot preservation for stopped/disabled agents is not yet guaranteed because current enabled units and launcher projections do not carry the persisted lifecycle fence; that acceptance evidence remains FCM-M3-002.
 
-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.
+Missing/stale generation, concurrent writer, unsafe path, ownership mismatch, unmanaged session, unsupported runtime, invalid projection, and lifecycle precondition failures return stable redacted JSON and non-zero status. No command targets fuzzy names, arbitrary sockets/commands/channels/secrets, or generated files as authority. Legacy sensitive values are never printed.

-## 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.

-## Recovery — rebuild generated env projections
-
-Each agent's `~/.config/mosaic/fleet/agents/<name>.env.generated` is a

-(`start-agent-session.sh`) sources at start. If an upgrade or a manual mistake

-`mosaic fleet regen` — do NOT restart the affected unit first.

-mosaic fleet regen --json     # same plan, machine-readable
-mosaic fleet regen --write    # rebuild fleet/agents/<name>.env.generated on disk
-```
-
-`regen` is projection-only and **never restarts an agent** — it has no path to
-systemd lifecycle. It is dry-run by default, deterministic/idempotent, uses the
-same roster→env mapping as `mosaic fleet reconcile`, and emits paths and counts
-only (never the projected `KEY=value` body). After `--write`, verify each unit
-resolves the intended values before restarting one unit at a time. The unit sets
-no `EnvironmentFile=` — `start-agent-session.sh` sources `.env.generated` itself —

-# Lease broker operations
-
-Place the socket and state file in a dedicated directory with mode `0700`. Start the packaged daemon with:
-
-```bash
-python3 "$MOSAIC_HOME/tools/lease-broker/daemon.py" \
-  --socket /run/user/1000/mosaic-lease/broker.sock \
-  --state /run/user/1000/mosaic-lease/state.json
-```
-
-The broker refuses an existing parent directory whose mode is not exactly `0700`, an existing state file not at `0600`, corrupt/incompatible state, or an already-existing socket path. After bind it sets the socket to `0600`. It never silently unlinks a pre-existing socket. On normal termination it unlinks only the socket inode it created, so it does not remove a replacement path.
-
-Before launching Claude, Claudex, or Pi, export the socket path; `mosaic` then runs the runtime through the packaged register-and-exec wrapper:
-
-```bash
-export MOSAIC_LEASE_BROKER_SOCKET=/run/user/1000/mosaic-lease/broker.sock
-mosaic claude # or: mosaic claudex, mosaic yolo claudex, mosaic pi
-```
-
-The wrapper obtains a broker-minted session ID and `exec`s the runtime without changing its PID/starttime anchor. The all-tools Claude `PreToolUse` hook and Pi `tool_call` handler inherit that identity. Claudex retains its isolated proxy environment and config directory; Mosaic merges the mandatory all-tools hook into that isolated `settings.json` before invoking the same wrapper. PRDY init/update, QA remediation, coord, orchestrator, and fleet launchers also converge on this boundary. Broker registration failure, unsafe isolated settings, or missing identity denies launch/tool execution fail-closed; broker timeout/unavailability and malformed replies also block tools.
-
-Run the permanent launch inventory locally with:
-
-```bash
-python3 packages/mosaic/framework/tools/lease-broker/check-runtime-launches.py --root .
-```
-
-The same check runs in the Mosaic package test suite and therefore in root CI. Any direct Claude/Pi binary launch must be replaced with `launch-runtime.py`, `execLeaseGatedRuntime`, or the gated `mosaic` runtime command; do not add static allowlist exceptions.
-
-Clients must complete the request boundary before waiting for a reply. After sending the single JSON object and its terminating newline, the client **MUST half-close the socket's write side** (`shutdown(SHUT_WR)` in POSIX clients; `socket.end()` in Node) and only then await the response. Merely calling `write()` and waiting is invalid: the broker waits for EOF to enforce the exact-one-frame contract and fails closed at its one-second deadline. Do not replace `end()` with `write()` in client helpers. A delayed second frame remains malformed and is rejected.
-
-There is no automated recovery workflow yet. `mosaic_context_recover` is reserved as the only unverified mutator class, but its fixed payload/receipt implementation lands in a later WI. After a crash, preserve the protected state file and restart only after verifying that no broker owns the socket. Restart intentionally clears all volatile VERIFIED leases. A leftover socket requires an operator to verify the owning service is stopped and remove that exact socket deliberately. Corrupt, oversized, symlinked, or non-regular state fails closed; do not overwrite it. Preserve it for incident review and establish new state only through an explicit operational decision, which invalidates prior sessions and tokens.
-
-## Security posture
-
-Directory `0700` plus socket/state `0600` is built-in same-principal hardening only: it excludes other UIDs but does **not** stop the same UID from unlinking and counterfeiting the socket. It therefore does not close T-C same-UID replacement. WI-1 does not provide a distinct-principal boundary. A stronger distinct-principal deployment requires an external protected proxy, ACL, or service boundary that clients cannot unlink or rebind and that preserves the authenticated client identity required by the broker's `SO_PEERCRED` and ancestry checks. Server-side branch protection remains the irreducible backstop.

-# 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:**

-   systemctl --user restart mosaic-agent@<name>

-`~/.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
-bridge. Codex has a separate link path managed by the legacy full skill-sync
-script; equivalent lifecycle management remains follow-up scope and is not
-changed here.

+# FCM-M5-001 Fleet Documentation Deferrals and Holds
+
+**Issue:** #758 · **Branch:** `docs/758-fleet-config-operator-docs`
+
+These are accepted existing DAG boundaries, not omissions silently claimed as delivered.
+
+## FCM-M3-002 hold
+
+- Boot/reboot preservation for roster members persisted stopped or disabled.
+- Current installation may enable all agent units, while the launcher projection does not yet carry
+  `lifecycle.enabled` or `desired_state`; documentation therefore does not claim lifecycle-safe reboot.
+- Heartbeat/liveness integration into roster-v2 `status`, `doctor`, and `verify`; current observations
+  cover systemd active state, tmux sessions, holder ownership, and unmanaged sessions only.
+
+## FCM-M4-002 hold
+
+- Executable v1-to-v2 cutover, reversible canary, and rollback.
+- Stale-projection/orphan migration classification and current-host managed/unmanaged fixture coverage.
+- Any live migration, lifecycle, systemd/tmux/session, or rollback action.
+
+M5 docs describe prerequisites and the preview boundary only. A ready preview is not migration or rollback evidence.
+
+## Explicit validate-operation gap
+
+- `FCM-REQ-03` requires a documented programmatic `mosaic fleet validate` operation.
+- The current CLI does not expose that operation. Existing mutation/reconcile validation and the
+  documentation example test are not a replacement for the missing command.
+- FCM-M5-001 documents this implementation gap without inventing syntax, JSON, exit behavior, or an
+  owning implementation card. Parent #758 must remain open until the requirement is implemented and
+  evidenced or the PRD/DAG is explicitly revised through the authoritative process.
+
+## FCM-M5-002 hold
+
+- Deterministic source-versus-installed asset revision detection and safe refresh implementation.
+- Rolling local canary, independent validator certificate, final release evidence, merge-gate approval, and parent #758 closure.
+
+`operations/upgrade-assets.md` is therefore a fail-closed hold, not an invented procedure.
+
+## Compatibility interpretation
+
+The M0 cross-cutting row requiring every retained/migrated artifact to validate through the executable contract is satisfied by each artifact's declared executable disposition, not by forcing versioned v1 fixtures through the v2 parser:
+
+- retained examples are explicit `version: 1` fixtures validated by the production v1 parser;
+- canonical profiles validate through the shared baseline plus `roles.local` resolver;
+- the service preset validates through its production service-policy reader;
+- migration candidates validate through the production v2 compiler and shared semantic resolver.
+
+The executable disposition inventory rejects undeclared additions/removals and prevents silent legacy drift.
+
+## Repository-wide documentation structure

+## Documentation completion checklist
+
+- [x] Root PRD exists and remains the #758 requirements authority.
+- [ ] The accepted project-specific fleet book is indexed, but it is not complete against `FCM-REQ-03`: the required explicit programmatic `mosaic fleet validate` operation is not implemented. The CLI reference and deferral report record this gap without inventing behavior.
+- [x] Sitemap links the fleet entry point and operator-critical pages.
+- [x] No HTTP/API/auth contract changed; OpenAPI/endpoint rows are not applicable.
+- [x] Working evidence remains under `docs/scratchpads/`; closure and deferral evidence remains under `docs/reports/`.
+- [x] Canonical source remains in-repository; no external publishing action is in scope.
+- [ ] Independent exact-head documentation review, PR CI, and FCM-M5-002 release certificate remain post-PR gates and are not claimed here.
+
+## Live-action boundary
+
+No migration, canary, rollback, deployment, systemd/tmux/session operation, generated projection, or product mutation was performed. `roster.yaml` remains the sole writable desired-state authority. `mos-comms` remains temporary. Parent issue #758 remains open.
+
+Validation command results and exact commit/tree evidence are recorded in the task scratchpad and PR body after execution.

-# 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.

-### PR opened + reported (2026-07-16)
-- **PR #802** http://git.mosaicstack.dev/mosaicstack/stack/pulls/802 — base `main`@`9745bc3f`,
-  head `34e55d4a` (commit `feat(mosaic): manifest-owned upgrade guard…`). 15 files, +1160/-142.
-- Reported PR head + red→green evidence to MS-LEAD (web1:mosaic-100); queued (lead busy).
-  Standing by for the independent-review commission at head `34e55d4a`.
-- **TWO items flagged to MS-LEAD for decision (awaiting reply):**
-  1. Deviation `.txt` vs `.json` — confirm accept (parity-tested) or convert to `.json`+jq.
-  2. `pr-create -i 791` appended `Fixes #791` → would auto-close the tracking issue on PR1 merge
-     while PR2/PR3 remain. Recommended edit to `Part of #791`; awaiting go-ahead to patch PR body.
-- DO NOT start PR2/PR3 until PR1 merges (DAG; one PR at a time).

-### 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.

-PR2 branch: `feat/791-pr2-snapshot-restore` off `origin/main` 32a0ffba. Same treatment applies:

-
-### 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
-  + `continue` on failure (keeps healing remaining files).
-- **E · should-fix — snapshot `umask 077` leaked process-global (install.sh).** Later sync copies/dirs
-  inherited 0600/0700. **Fix:** save `old_umask`, restore on EVERY return path (`# UMASK-RESTORE-NORMAL`).
-  **Test:** Part 8 — synced framework file is 0644 while the secret backup stays 0600; control (restore
-  stripped) makes the synced file 0600.

-
-### PR3 scope (ratified §4/§7 of design doc) — `mosaic fleet regen`
-Projection-only recovery command: rebuilds each `fleet/agents/<name>.env.generated` from `roster.yaml`
-(SSOT). Dry-run default; `--write` applies; `--json` machine output. Structural guarantee: NO code path to
-systemd lifecycle — **never restarts an agent**. Single-SSOT: reuses `projectRosterV2AgentGeneratedEnv`
-(extracted, shared with the reconciler apply path) so regen and reconcile cannot drift. Secrev: paths +
-counts only, never the rendered KEY=value body.
-
-New files: `commands/fleet-regen-command.ts` (+ `.spec.ts`), guide `docs/guides/upgrade-safety-and-recovery.md`
-(three-layer model: PR1 manifest ownership → PR2 snapshot/restore → PR3 regen; do-NOT-restart-before-verify
-runbook), regen reference added to `docs/guides/fleet-local-canary.md`. Wired in `commands/fleet.ts`.
-
-### 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.

-
-## 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.

-# 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.
-- [x] Implementation complete.
-- [x] Relevant tests and repository gates green.
-- [ ] Commit pushed and PR opened.
-
-## Tests and evidence
-
-- RED (before source fix): `packages/mosaic/framework/tools/glpi/test-list-http-status.sh` → exit 1; ticket/computer/user 206 assertions failed, all 401 assertions passed.
-- GREEN: `bash -n packages/mosaic/framework/tools/glpi/{ticket-list.sh,computer-list.sh,user-list.sh,test-list-http-status.sh}` → pass.
-- GREEN: `shellcheck packages/mosaic/framework/tools/glpi/test-list-http-status.sh` → pass.
-- GREEN: `packages/mosaic/framework/tools/glpi/test-list-http-status.sh` → 6 assertions pass (206 renders and 401 errors for all three wrappers).
-- 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.

-
-## 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.

-- 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.

-
-## 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.

-## Locked constraints
-
-- Build against the ratified design; do not re-derive it.
-- Product code only in `packages/mosaic`; Gate0 Python probes are reference prototypes and are not shipped.
-- Caller-supplied/asserted `session_id` is refused.
-- Tokens use the operating-system CSPRNG via Python `secrets`; never `Math.random` or model output.
-- Socket parent directory mode `0700`, socket mode `0600` minimum; document distinct-principal deployment as the stronger T-C-closing posture.
-- Red-first TDD for six named cases; new-code coverage >=85%.
-- No merge. PR must say `closes #828`; exact 40-character head handed to Mos for Opus-SECREV and independent review.
-
-## Plan
-
-1. Load security/testing/docs guidance and inspect existing `packages/mosaic` architecture.
-2. Write the six required tests first and capture RED evidence.
-3. Implement minimal broker modules and CLI/runtime integration necessary for product use.
-4. Run focused tests with coverage, package gates, then full repository gates/suite.
-5. Run author-side review/remediation, commit `closes #828`, queue guard, push, and open PR through Mosaic wrappers.
-6. Send PR number + exact head SHA to `web1:mosaic-100`; stop without merging.
-
-## Risks / boundaries
-
-- Same-UID counterfeit socket replacement remains the disclosed T-C residual unless broker runs under a distinct principal; filesystem modes alone are minimum hardening, not a complete authenticity proof.
-- `.mosaic/orchestrator/mission.json` and `.mosaic/orchestrator/session.lock` were already modified at session start and must not be included in this PR.
-- Repository Woodpecker pipelines exist; CI is the canonical build path. No manual image build/deploy is in scope.
-
-## Progress / evidence
-
-- 2026-07-18 session start: mandatory mission files and orchestration guides loaded.
-- STEP 0: all four authority hashes matched; artifacts read in full.
-- Branch/HEAD confirmed; issue #828 open; Gate0 evidence hash confirmed.
-- Initial RED: focused Vitest acceptance suite failed 11/11 because the product daemon did not exist; the expected missing-product failure was observed before implementation.
-- Review-remediation RED: partial/zero-progress state writes, nested corrupt state, symlink state, canonical starttime, and duplicate-anchor generation behavior failed before their fixes. Real socket RED/GREEN runs were executed by the unrestricted parent harness because the delegated worker sandbox denies `AF_UNIX.bind()`.
-- Product implementation added at `packages/mosaic/framework/tools/lease-broker/daemon.py`; Gate0 probe scripts were read as references but not copied or shipped.
-- Independent Codex code review round 1 found 2 blockers + 1 should-fix (connection stall/crash, partial writes, packet-dependent framing); all were remediated with tests.
-- Independent Codex code review round 2 found 2 blockers + 1 relevant should-fix (half-close contract ambiguity, incomplete persisted-state validation, symlink/non-regular state); all were remediated with tests and documentation. Pre-existing `.mosaic/*` session dirt remains excluded from the PR.
-- Unrestricted focused situational suite: `35/35` GREEN.
-- New Python product module coverage: `90%` (`356` statements, `36` missed), above the user-required 85%.
-- Root typecheck: `42/42` Turbo tasks GREEN.
-- Root lint: `23/23` Turbo tasks GREEN.
-- Root format check: GREEN.
-- Package build + suite: `71/71` files and `1,369/1,369` tests GREEN, including framework shell tests.
-- Full root suite: `43/43` Turbo tasks GREEN after the oversized-frame production race fix.
-- Focused acceptance suite: `35/35` GREEN in three consecutive unrestricted runs; exact-head instrumented run also `35/35` GREEN.
-- Exact-head Python product coverage: `90%` (`365` statements, `37` missed), above the required 85%.
-- Review-triggered oversized-frame race was fixed in production by bounded drain-to-EOF; tests were not changed.
-- Commits banked in red/green cadence: `d61c5441` (RED contract), `deb11df7` (GREEN implementation/docs), `57770e34` (oversized-frame production fix).
-- Final-review blocker remediated: added a 256-token pending-state cap, deletion on consume/generation revocation, pre-open serialized-size enforcement, and request-wide in-memory rollback for every broker mutation/commit failure while retaining the v1 live-token schema.
-- Distinct-principal docs now state built-in `0700`/`0600` is same-principal only; WI-1 does not provide the external identity-preserving proxy/ACL/service boundary needed for the stronger deployment.
-- Exact Python unit suite: `8/8` GREEN. Unrestricted focused acceptance: `35/35` GREEN.
-- Exact-head package build/suite: `71/71` files and `1,369/1,369` tests GREEN.
-- Exact-head Python product coverage: `90%` (`376` statements, `36` missed), above required 85%.
-- Root typecheck: `42/42` GREEN. Root lint: `23/23` GREEN. Root format check and `git diff --check`: GREEN.
-- Final exact-head rereview found two persistence blockers: post-rename directory-fsync uncertainty and acceptance of impossible persisted token records. RED was captured as three invariant failures plus one missing fail-stop error; commits `a94b1220` (RED) and `d05465e5` (GREEN) remediate both without weakening tests.
-- Post-remediation evidence: Python unit suite `10/10`, focused real-socket acceptance `35/35`, full root suite `43/43` Turbo tasks, broker coverage `90%` (`395` statements, `38` missed), lint `23/23`, typecheck `42/42`, format check and `git diff --check` GREEN.
-- Independent Codex review of remediation commit `d05465e54736c4966294c4af8fbd6a4ad8fe81aa`: APPROVE, confidence `0.94`, zero findings. Reviewer sandbox could not allocate temp directories; unrestricted parent test evidence above is canonical.
-
-- Remediation session: terra review comment `18072` reproduced a SERIAL-ACCEPT DoS; scope is RED regressions plus bounded concurrent connection handling on PR #836, preserving all existing broker security properties.
-- RED evidence against reviewed daemon: four silent peers delayed registration `3920 ms` beyond the `1500 ms` bound; 16 silent peers were not reaped within `2500 ms`. The first bounded implementation then exposed slot exhaustion by rejecting the valid queued caller with `EPIPE`; admission was corrected to wait for a reclaimed bounded slot. GREEN evidence: queued-peer test `211 ms`; strengthened cap/reap/reclaim test `1118 ms`; complete real-socket acceptance `37/37` and Python persistence suite `10/10`.

-# WI-2 Scratchpad — Whole mutator-class gate
-
-- **Issue:** Gitea #829
-- **Branch:** `feat/829-mutator-gate`
-- **Base HEAD:** `8ec67a1126adb0dcd4c3a2bf5525f3e239c0b201`
-- **Role:** sol author/build lane only; terra code review and Opus security review are coordinator-owned.
-
-## Mission prompt
-
-Implement BUILD-BRIEF Deliverable 2 as a framework-native whole mutator-class gate under `packages/mosaic/`, building against the merged WI-1 lease broker. No consequential mutator may succeed while UNVERIFIED after a compaction observer fires or after TTL. Carry the T-B compromised-tool acceptance criteria. Enforce revoke-first and promote-last structurally. A receipt is only a promotion prerequisite; the mutator-class gate remains the safety mechanism. M1 is Claude + Pi only.
-

-
-## Plan
-
-1. RED real-socket acceptance tests for default-deny whole classes, T-B raw-tool bypass, observer/TTL revocation, and structural revoke-first/promote-last.
-2. Extend the merged WI-1 broker as the sole lease authority; authenticate every transition through existing peercred/ancestry/session logic and consume WI-1 single-use cycle tokens atomically before promotion.
-3. Add one broker-backed runtime gate executable and wire it across all Claude `PreToolUse` tools and Pi `tool_call`; unknown/custom tools deny by default.
-4. Add proportional protocol/security/operations documentation and requirements-to-evidence mapping.
-5. Run focused coverage, package/full suites, lint/typecheck/format, then queue-guard, push, open an unmerged PR with `closes #829`, and hand off the exact head.
-
-## Risks and bounds
-
-- Receipt parsing/builders and compaction observers are later WIs; WI-2 exposes the promotion prerequisite boundary but does not treat a receipt as safety authority.
-- Broker restart intentionally loses volatile VERIFIED leases and therefore restarts UNVERIFIED; persistent WI-1 identity/token state remains unchanged.
-- The gate is whole-class and does not parse shell command strings. T-C extension/hook absence and same-UID broker replacement remain outside the client guarantee and server branch protection remains the backstop.
-- Initial lease TTL is capped at ratified 300 seconds; callers may only shorten it.
-- Working budget assumption: 35K tokens; reduce documentation/refactor breadth before touching locked scope if pressure rises.
-
-## Progress and verification
-
-- RED #1: all 5 initial real-socket contract tests failed on WI-1 with `UNKNOWN_ACTION` or missing adapter behavior.
-- RED #2: register-before-exec runtime test failed because `launch-runtime.py` did not exist.
-- GREEN: broker-owned volatile lease state, 300-second maximum monotonic TTL, WI-1 token-backed promotion, all-tools runtime gate, Claude/Pi wiring, and register-before-exec launcher delivered without changing WI-1 peercred/ancestry authority.
-- Focused broker + gate acceptance: `43/43` GREEN.
-- Instrumented Python coverage: `88%` total — daemon `89%`, register/exec launcher `86%`, runtime gate `86%`.
-- Full repository suite: `43/43` Turbo tasks GREEN; `@mosaicstack/mosaic` `72/72` files and `1,377/1,377` tests GREEN.
-- Root typecheck: `42/42`; lint: `23/23`; format check and `git diff --check`: GREEN.
-- No author self-review was run. Exact-head terra CODE and Opus SECREV remain coordinator-owned gates.
-
-## Acceptance mapping
-
-| Acceptance criterion | Evidence |
-| --- | --- |
-| No consequential mutator succeeds while UNVERIFIED after observer revoke or TTL | `observer revocation and monotonic TTL expiry deny the next mutator` real-socket acceptance test |
-| T-B compromised-tool bypass is covered by the whole gate | `T-B raw and custom mutator tools are default-denied without shell parsing` across Claude/Pi built-ins, raw Bash class, MCP/custom/unknown tools |
-| Revoke-first / promote-last is structural | `revoke-first and promote-last structurally bracket mutator authority`; direct promotion rejected, pending remains denied, token consumption commits before VERIFIED |
-| Consume WI-1 auth/lease substrate | All transitions and decisions traverse merged peercred/ancestry authentication; promotion consumes the exact WI-1 CSPRNG cycle token |
-| M1 Claude + Pi | Claude `.*` PreToolUse and Pi `tool_call` invoke the same broker gate; register-before-exec test proves broker-minted parent identity reaches runtime descendants |
-
-## Locked discipline
-
-- Re-verify and read the four authority artifacts before design or code.
-- RED-first tests must cover unverified mutation refusal, T-B compromised-tool refusal, and revoke-first/promote-last ordering.
-- Consume WI-1 VERIFIED-lease state; do not re-derive kernel identity, ancestry, sessions, or token authentication.
-- Minimum 85% new-code coverage; full suite, lint, typecheck, and format checks green.
-- Build only: no self-review and no merge. Open a PR containing `closes #829`, report its exact 40-character head, then exit.

-## Remediation — terra CODE comment 18091
-
-- Coordinator correction: terra returned REQUEST CHANGES at head `77b137ccc04b5be035cac5ca21bbbf3df8b94f97`; Opus SECREV was GO and CI green, but no evidence transfers to the remediated head.
-- BLOCKER 1 verified: first-class Claude/Pi route through `execLeaseGatedRuntime`, while the supported Claudex path preserves isolation but directly invokes `claude`; it therefore registers no anchor, injects no lease session, and the isolated config has no guaranteed all-tools gate hook.
-- BLOCKER 2 accepted: prior 88% was aggregate evidence. Remediation must produce independently measured branch coverage of at least 85% for each new executable (`launch-runtime.py`, `mutator-gate.py`, and daemon delta evidence), including successful exec-boundary collection and validation/error branches.
-- Remediation discipline: RED tests first; preserve the reviewed-good broker lock/state-transition ordering; update PR #837 on the same branch; no self-review or merge.
-
-### Remediation evidence
-
-- RED commit `046896c6`: both `mosaic claudex` and `mosaic yolo claudex` behavioral probes exited 1 because the direct path supplied neither a broker session nor the isolated all-tools hook; branch-focused Python tests failed on the absent injectable boundaries. Fresh WI-2 daemon-delta instrumentation also failed the ≥85% branch gate at 75%.
-- GREEN: Claudex now exposes only `execLeaseGated`, passes the preserved isolated proxy environment through the shared register-before-exec wrapper, and merges the exact `.*` mutator hook into isolated `settings.json` with mode `0600`. Missing broker/identity, malformed or symlinked settings, and an unverified consequential tool all fail closed. The broker transition/lock implementation was not changed.
-- Behavioral regression: normal and YOLO Claudex both receive a 64-hex broker session, retain their mode-specific arguments, observe the exact all-tools hook, and receive status 2 for unverified `Bash`.
-- Independent branch coverage: `launch-runtime.py` 16/18 = **89%** (statements 98%); `mutator-gate.py` 21/22 = **95%** (statements 99%); `daemon.py` WI-2 delta 35/40 = **88%** (whole-file branch 80%, statements 90%).
-- Fresh focused real-socket coverage run: WI-1 + WI-2 acceptance `46/46`; persistence `10/10`; branch unit suite `10/10`.
-- Fresh full repository suite: `43/43` Turbo tasks; `@mosaicstack/mosaic` `72/72` files and `1,381/1,381` tests.
-- Fresh root gates: typecheck `42/42`; lint `23/23`; format and `git diff --check` GREEN.
-- PR #837 remains open and unmerged. Terra CODE and Opus SECREV must both rerun from zero on the exact remediated head before coordinator-owned merge authorization.
-
-## Remediation round 3 — terra CODE comment 18099 + binding upgrade
-
-- Locked-good surfaces: Claudex gating and B2 per-executable coverage are verified; do not regress them. Broker state-transition/lock ordering remains untouched.
-- Mechanical repository sweep found direct executing Claude entries in PRDY init, PRDY update, QA remediation, and `@mosaicstack/coord` task launch. It also found a direct Claude command rendered into the QA report template and documentation examples. Existing Mosaic CLI Claude/Pi/Claudex, orchestrator session-run, and fleet starts already reach the gated boundary.
-- Elevated hard requirements: ship a permanent suite/CI guard that scans production source and fails on any direct Claude/Pi launch; route every executing entry through one common gated wrapper; add real-broker RED/GREEN tests for PRDY init/update and QA; preserve each environment and denial behavior; independently measure all new executable coverage at ≥85%.
-- Round-3 plan: first commit RED behavioral and scanner-contract tests; then add one framework `launch-runtime.sh` choke-point over `launch-runtime.py`, make Mosaic CLI and shell launchers use it, make coord route through `mosaic`, and wire the permanent guard into package tests. Update all discovered operator-facing direct-launch examples so the scanner inventory remains complete.
-
-### Round-3 outcome
-
-- RED commit `7f3418fa`: PRDY init, PRDY update, and QA remediation all reached the fake Claude binary without a broker session even when the configured socket did not exist; the permanent-guard contract initially failed because its executable was absent, then failed against the five discovered direct entries (four executing plus the QA command template).
-- Choke-point decision: a new shell layer was unnecessary. Every executing repository entry now converges directly or through `mosaic`/`execLeaseGatedRuntime` on the existing single `launch-runtime.py` register-then-exec wrapper. PRDY and QA preserve their working directories, prompts, flags, logging pipe, and environment. Coord rewrites direct Claude commands to `mosaic claude` and rejects unknown custom Claude launchers fail-closed.
-- Permanent guard: `packages/mosaic/framework/tools/lease-broker/check-runtime-launches.py`, invoked by `packages/mosaic/package.json` `test:framework-shell` and therefore root `pnpm test`/CI. It scans production code under `packages/`, `apps/`, `plugins/`, and `tools/` and rejects literal, absolute-path, process-API, command-array, and dynamic Claude/Pi launch forms. Synthetic bypass tests are permanent at `runtime_launch_guard_unittest.py`.
-- Mechanical inventory: **14 gated / 14 total** — coord 2, fleet 1, QA 2, orchestrator 3, PRDY 2, Mosaic Claude/Pi/Claudex adapter/boundary 4. No verification-layer fallback or follow-up issue is needed because the single code-level wrapper was achieved.
-- Real-socket behavioral evidence: PRDY init, PRDY update, and QA remediation each fail before runtime execution when the broker is absent; with the broker present they receive a broker-minted 64-hex session and the unverified `Bash` authorization exits 2. Claudex normal/YOLO and the broker state machine remain GREEN.
-- Fresh branch coverage: `launch-runtime.py` **18/18 = 100%**; `mutator-gate.py` **22/22 = 100%**; permanent guard **36/38 = 95%**; `daemon.py` WI-2 delta **35/40 = 87.5%**. All attributable executable statement coverage is at least 98%.
-- Fresh focused suites: broker + mutator real-socket acceptance `49/49`; persistence `10/10`; launcher/gate branch suite `13/13`; permanent guard suite `7/7`; coord `19/19`.
-- Fresh full repository suite: `43/43` Turbo tasks; `@mosaicstack/mosaic` `72/72` files and `1,384/1,384` tests. Root typecheck `42/42`, lint `23/23`, format, and diff checks GREEN.
-- PR #837 remains open and unmerged. Terra CODE and Opus SECREV must both rerun from zero on the exact round-3 head before coordinator-owned merge authorization.

-## Remediation round 4 — terra CODE comment 18104
-
-- Locked-good surfaces: the 14/14 launch inventory, single `launch-runtime.py` choke-point, real-socket launcher behavior, coverage, Claudex gating, and broker state machine must not change.
-- Reproduced RIDER E exactly at head `1792b7934dda7eff64a207b8b0edb9c460d4164b`: a temporary production file containing `exec claude --dangerously-skip-permissions "terra-r3" # launch-runtime.py` made the guard exit 0 and report `1 gated/1 total`.
-- Root cause: classification searched the unparsed physical line, and the broad gated regex treated any `launch-runtime.py` substring—including comments and inert arguments—as an invocation before the direct-launch finding was evaluated.
-- Round-4 plan: add permanent RED cases for the exact comment evasion plus string-argument, echo, and unrelated-variable marker evasions; tokenize/strip comments by launcher syntax; recognize only command-position wrapper invocations with `--runtime` and the gated command separator; retain 14/14 real inventory; rerun guard coverage and all gates fresh.
-- Mos Rider A/B decision: adopt **both** defenses. Command-position parsing remains necessary because a normal `claude -p` launch is consequential even without the dangerous flag. The primitive-location invariant is more mechanically robust for dangerous mode because it does not need to recognize a wrapper marker at all. Move the sole raw `--dangerously-skip-permissions` literal into `launch-runtime.py`; any occurrence in another production file is independently RED.
-- Rider-A RED matrix adds heredoc body, backslash continuation, non-first `;`/`&&`/pipe commands, command substitution, `eval`, and variable-execution indirection in addition to the six marker/comment evasions. Before the augmented implementation, primitive ownership, command substitution, `eval`, variable execution, and the preserved 14-site inventory all fail.
-- Round-4 GREEN uses both defenses. Quote-aware comment stripping removes shell/Python `#` and JS/TS line/block comments; shell command prefixes are segmented with `shlex`; validated wrappers require `launch-runtime.py` in command position, `--runtime`, and the `--` command separator; multiline TypeScript wrapper calls are validated as complete invocations. Direct command syntax wins over markers, while tracked runtime assignments plus `eval`/variable execution, command substitution, chained commands, heredocs, continuations, and `env`/`command`/`nohup` prefixes are rejected.
-- Primitive ownership is independently load-bearing: `launch-runtime.py` is the sole production owner of the raw Claude dangerous flag. Mosaic, Claudex, and PRDY request semantic `--dangerous`; the wrapper validates Claude and injects the primitive immediately before register/exec. This preserves actual YOLO argv behavior while making any raw primitive elsewhere fail without relying on wrapper-name recognition.
-- Permanent guard suite now has 10 tests and 31 direct-launch forms, including 18 new round-4 marker/comment/indirection/prefix evasions plus harmless-marker and multiline-wrapper controls. Terra's exact add-ungated source is exercised through the CLI effectiveness test. Repository inventory remains exactly **14 gated / 14 total**.
-- Fresh round-4 coverage: guard **97%** branch-aware aggregate (241 statements, 110 branches); `launch-runtime.py` **100%**; `mutator-gate.py` **100%**. The daemon is byte-unchanged from the round-3 head whose WI-2 delta is **87.5%**.
-- Fresh round-4 gates: real-socket acceptance **49/49**; persistence **10/10**; launcher/gate **14/14**; guard **10/10**; coord **19/19**; Mosaic **1384/1384**; root **43/43**; typecheck **42/42**; lint **23/23**; format and diff checks green.
-
-## Remediation round 5 — terra 18116 + Opus 18114
-
-- Both independent gates converged on one guard-only completeness gap at round-4 head `1eb77c17f3147d4fa9944f77f1826243135b9cc0`; all round-4 primitive anchoring, command-position parsing, 14/14 inventory, broker ordering, and coverage remain locked-good.
-- Reproduced exactly: a temporary production source containing `launcher=claude` followed by `exec "$launcher" -p x` exits 0 with `0 gated / 0 total`. The literal command resolver skips prefixes but cannot resolve a tracked variable; the variable resolver handles only bare/eval references and cannot skip prefixes.
-- Round-5 plan: add 10 permanent RED forms (quoted/unquoted `exec`, `command`, `nohup`, and `env` with assignment, each multiline and same-line), then unify shell command-position resolution so literal and tracked-variable terminal tokens traverse the same prefix parser. Retain an independent variable-reference backstop, the 14/14 inventory, and every round-4 regression.
-- Mos stopping-criterion augment: command parsing is explicitly best-effort rather than a complete shell interpreter. Add B1 proving a parser-exotic alias launch with the raw dangerous flag is still RED by primitive anchoring, and B2 proving a parser-missed non-dangerous alias launch reaches the global `.*` hook and fails closed with `GATE_UNAVAILABLE` when no lease session exists. Document A (realistic parser matrix) + B (robust residual backstops); fresh reviewers supply criterion C (no new non-overlapping finding).
-- RED commit `91a4a983`: all 10 prefix×variable cases failed as expected before the fix—quoted/unquoted `exec`, `command`, `nohup`, and `env A=1`, each in multiline and same-line assignment shapes.
-- GREEN structural resolution: `shell_command_tokens()` now owns command-position prefix skipping for both literal and variable callers, including nested `exec`/`command`/`nohup`/`env` ordering. `runtime_variables` is threaded into `is_shell_direct_invocation()` and the same terminal-token resolver backs `executes_runtime_variable()`; exact `$v` and `${v}` references are resolved after `shlex` removes quoting. Same-line runtime assignment delimiters include shell operators.
-- Residual backstops: B1 proves alias-indirected dangerous mode is classified `dangerous-primitive` even though the parser does not resolve the alias. B2 proves a non-dangerous alias residual remains parser-missed, then verifies the shipped global `.*` Claude hook and status-2 `GATE_UNAVAILABLE` denial for representative read, mutator, and custom/MCP tools without a lease session.
-- Stopping-criterion evidence A+B is committed in tests and architecture docs; C remains the fresh exact-head terra/Opus determination. Repository inventory remains exactly **14 gated / 14 total**.
-- Fresh round-5 coverage: permanent guard remains **97%** branch-aware aggregate (251 statements, 112 branches). Locked-good launcher and mutator-gate executables remain unchanged at their round-4 **100% / 100%** evidence.
-- Fresh round-5 gates: real-socket acceptance **50/50**; persistence **10/10**; launcher/gate **14/14**; guard **12/12**; coord **19/19**; Mosaic **1385/1385**; root **43/43**; typecheck **42/42**; lint **23/23**; format and diff checks green.

-# Issue #838 — Broker acceptance socket flake
-
-## Objective
-
-Eliminate high-contention uncaught JSON parse failures in lease-broker and mutator-gate acceptance helpers without laundering malformed/empty replies into passing assertions.
-
-## Constraints
-
-- Branch: `fix/838-broker-acceptance-flake` in `/home/hermes/agent-work/stack-838-flakefix`.
-- Red-first TDD with a forced empty/truncated reply path and deterministic rejection or documented retry.
-- Read newline-framed replies completely; reject malformed broker replies with byte length/content context.
-- Determine RIDER2 branch before finalizing: test-harness-only `(a)` or daemon write truncation `(b)`.
-- If product-side, prove the real Claude/Pi adapter read path fails closed; fix any allow-risk.
-- Coverage >=85% per changed executable through real tests.
-- Full suite and repository gates green; independent exact-head review required.
-- Push and open a PR containing `closes #838`; do not merge.
-
-## Progress
-
-- 2026-07-17: Reclaimed from #824. Confirmed clean worktree on `fix/838-broker-acceptance-flake` at main base `abd2791f59b3f06f46dd08e55298ced72f6aa7c2`.
-- RED evidence: after dependency setup, `broker-test-client.spec.ts` failed to load the intentionally absent shared client module. Its contract forces empty-close retry, repeated truncated-close rejection with byte context, and newline-terminated malformed-reply rejection.
-- RIDER2 verdict: branch **(b)**. `daemon.py` starts one connection deadline before request reading, then may spend that budget waiting for `broker_lock`; after handling, `remaining <= 0` returns without writing. A timed `sendall` failure can likewise close after a partial write. A deterministic socketpair probe held the lock past `CONNECTION_DEADLINE_SECONDS` and observed `deadline_probe_reply_length=0`.
-- Adapter tripwire: real subprocess executions of `mutator-gate.py` for both `--runtime claude` and `--runtime pi` against actual Unix servers returning empty and truncated replies all exited 2 with `GATE_UNAVAILABLE`. Adapter fail-close is proven; there is no ALLOW risk.
-- Residual: production broker reply loss remains an availability-denial path under extreme contention, but cannot grant mutator authority. The acceptance-only client retries early closes and otherwise rejects with response byte length, escaped bytes, and hex; malformed newline-framed replies are never retried or converted to reply objects.
-- Shared client now owns newline framing and parsing for both acceptance suites. Focused suites pass 60 tests, including the real adapter tripwire.
-- Coverage gate: changed helper is 100% statements/lines/functions and 90% branches; existing `skill.ts` remains above 85% per-file thresholds.
-
-## Scope corrections and bounded product repair
-
-- Coordinator correction superseded the initial push/PR and retry language: this lane is BUILD-ONLY, and early-close retries are forbidden because they can mask a committed broker transaction. Nothing may be pushed or opened until explicitly cleared.
-- Revised RED evidence: the no-retry empty/truncated tests failed because the first failed exchange was retried into `{ ok: true }`; the daemon regression failed because a slow completed `broker.handle()` produced `b''` instead of a newline-framed reply.
-- Client repair: both former duplicated helpers use one shared reader. Empty, truncated, malformed, oversized, timed-out, and socket-error replies reject `BrokerTransportError` with a typed `kind`, attempt count fixed at one, response length, escaped bytes, and hex. No retry and no catch-to-reply conversion exists.
-- Product repair: `daemon.py` now has independent bounded read, broker-lock queue, and send budgets. Lock queue exhaustion returns explicit `BROKER_BUSY` before `broker.handle()` can mutate state. Once handling starts it finishes atomically, and its reply always receives a fresh send timeout instead of being skipped because read/lock/fsync consumed a shared deadline.
-- Product GREEN evidence: deterministic socketpair tests prove lock saturation returns framed `BROKER_BUSY` without invoking `handle()`, and a handle that completes after the former one-second shared deadline still returns its complete framed reply.
-- RIDER2b remains **fail-closed**: real Claude and Pi `mutator-gate.py` subprocesses against empty and truncated Unix-socket replies exit 2 with `GATE_UNAVAILABLE`; no malformed/default ALLOW was observed.
-- Residual/tripwire: an unavoidable peer disconnect or send failure can still lose acknowledgement after a valid transaction commits. The affected adapter call fails closed. A valid `promote_lease` may nevertheless remain VERIFIED after its acknowledgement is lost; that is authority-observability divergence requiring WI-3/Opus security review rather than expansion of #838. #838 does not add retries or attempt a protocol redesign.
-- Final package evidence: recursive Mosaic dependency build passed; 73 Vitest files / 1,392 tests passed; deadline unit tests 2/2, real runtime tool tests 15/15, launch guard tests 12/12, inventory 14/14, and shell regressions passed.
-- Final coverage: `broker-test-client.ts` 99.24% statements/lines, 86.11% branches, 100% functions under per-file >=85% thresholds. Repository typecheck 42/42, lint 23/23, and format check passed.
-- Independent Codex exact-head review requested one framing fix: a valid frame followed by trailing bytes in a later socket chunk could resolve before the garbage arrived. Security review also flagged complete token-bearing reply bodies in diagnostic properties/logs.
-- Review RED evidence: delayed cross-chunk garbage resolved `{ ok: true }` instead of rejecting, and a truncated `promotion_token` remained in the typed error. The tests use separate timed writes to prevent kernel/event-loop coalescing.
-- Review remediation: the shared client now accumulates through EOF, requires exactly one terminal newline, then parses inside a rejecting error boundary. Diagnostic bodies are capped at 256 bytes, sensitive broker fields are fully redacted, and a SHA-256 digest preserves correlation without credential disclosure.
-- Post-review coverage: `broker-test-client.ts` 99.35% statements/lines, 86.66% branches, 100% functions. Final full suite is 73 files / 1,394 tests plus all Python/shell gates; recursive build, typecheck, lint, and format are green.
-- Fresh exact-head Codex security review: risk `none`, no findings. Fresh code review found only that the real-adapter subprocess proof lacked a timeout; it now has a five-second bound and fails with runtime/wire context while closing the fake server. The focused Python suite remains 15/15 green.
-- Mandatory Opus SECREV remains coordinator-owned and pending before any push/PR decision; this build is intentionally local-only.

+- Branch: `docs/758-fleet-config-operator-docs`
+- Exact base: `9745bc3f29c26b021a478b7ad03cfb494f6c9de3` (tree `4da210da9a71b035130d4160a4a2e691bdfde2da`)
+
+## Objective
+
+Deliver the accepted fleet documentation information architecture, operator workflows, operations and migration references, comprehensive contract documentation, and deterministic link/example validation without live fleet action or product mutation.
+
+## Scope and constraints
+
+- Documentation, examples, documentation validation, and tracking only.
+- `roster.yaml` remains the sole writable desired-state authority; generated state is derived/observed.
+- No M4-002 implementation or execution; no canary, migration, rollback, deployment, systemd/tmux/session, generated projection, or product mutation.
+- `mos-comms` is temporary and is not permanent architecture.
+- Parent issue `#758` remains open through M5.
+- No credentials, sensitive values, or privileged command content.

+2. Map the M0 checklist and current implementation behavior to documentation pages.
+3. Author operator, operations, migration, schema/reference, recovery, troubleshooting, and security/authority docs.
+4. Add or extend deterministic documentation/link/example validation if required, red-first.
+5. Run repository documentation, link, example, and relevant package checks; review and remediate.
+6. Commit, queue-guard, push one branch, and open one wrapper-created PR; stop for independent review.

+- [x] Loaded repository/global delivery and documentation contracts.
+- [x] Verified `origin/main` is exact required base and created isolated worktree.
+- [x] Tracking updated first.
+- [x] Checklist mapped and docs authored.
+- [x] Validation green.
+- [x] Review/remediation complete.
+- [x] Commit, queue guard, push, PR #789.
+- [x] Rejected exact-head RoR findings repaired on a new descendant commit candidate.
+- [ ] New exact-head review and CI after repair push.
+
+## Tests and verification
+
+- Red-first documentation validator initially failed for the absent fleet entry point and canonical
+  example, then passed after the IA and example were added.
+- `pnpm --filter @mosaicstack/mosaic exec vitest run src/fleet/roster-v2.spec.ts src/fleet/example-profile-dispositions.spec.ts src/fleet/fleet-documentation.spec.ts src/fleet/v1-v2-migration.spec.ts src/fleet/generated-env-boundary.spec.ts src/fleet/fleet-agent-crud.spec.ts src/fleet/fleet-reconciler.spec.ts` — 7 files, 195 tests passed after building workspace dependencies.
+- `pnpm format:check` — passed.
+- `pnpm lint` — 23 tasks passed.
+- `pnpm typecheck` — 42 tasks passed.
+- `pnpm test` — 43 tasks passed; `@mosaicstack/mosaic` contributed 61 files and 1,045 tests.
+- `bash packages/mosaic/framework/tools/quality/scripts/verify-sanitized.sh` — passed.
+- `bash packages/mosaic/framework/tools/quality/scripts/check-resident-budget.sh` — passed.
+- `git diff --check` — passed before final review.
+- Independent staged-snapshot review identified four documentation/validation blockers: reboot safety,
+  heartbeat observation, migration failure envelope, and example-scan coverage. All were remediated;
+  focused rereview approved the staged remediations with no blockers. Exact committed-head review remains
+  a post-PR gate.
+- Post-remediation `@mosaicstack/mosaic` lint/typecheck passed; package test passed 61 files / 1,045
+  tests; sanitization and resident-budget gates passed again.
+
+- Post-PR exact-head RoR on rejected head `0aee2c09819fd06e28f927384ea56fa2ef374edf`
+  identified five blockers: update-lifecycle overclaim, missing explicit `fleet validate` gap,
+  fragment-blind link validation, unsupported checklist-evidence claim, and insufficient example safety
+  validation. Red-first regressions failed before implementation for missing-heading, privileged-command,
+  and credential-format fixtures. Repairs now preserve/document implementation truth, validate heading
+  fragments, narrow checklist claims, and scan fenced/canonical examples for common credential formats
+  and privileged commands without printing fixture values.
+- Repair-focused fleet contracts: 7 files, 192 tests passed after review remediation; documentation
+  validator contributed 11 tests. Full gates passed: format; lint 23/23; typecheck 42/42; test 43/43
+  tasks with `@mosaicstack/mosaic` 61 files / 1,052 tests; sanitization; resident budget; and
+  `git diff --check`. New exact-head review/CI remain pending until the repair commit is pushed.
+
+## Risks/blockers
+
+- Checklist may include behavior intentionally deferred to M4-002/M5-002; such items must be recorded as approved-existing holds rather than claimed delivered.
+- Commands/examples must remain non-live and avoid privileged/sensitive content.
+
+## Final evidence
+
+- Pending.

-# 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 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).

-Skill names are direct children using `[A-Za-z0-9][A-Za-z0-9._-]*`, not paths. Registration rejects traversal/control characters and never replaces foreign files, directories, or symlinks; unregister removes only links that point inside the canonical Mosaic skill root. After registering during a running Claude Code session, use `/reload-skills` or start a new session.
-
-M1 lifecycle management targets Claude Code. Pi can discover the canonical Mosaic root through its launcher configuration. Codex parity remains follow-up scope and continues to use the existing full skill-sync linker.

-# test-upgrade-durable-snapshot.sh — the #791 PR2 regression gate.
-#
-# PR1 gave keep-mode upgrades two protections: the manifest (a keep-sync only
-# ever writes framework-owned paths — operator config is structurally untouched)
-# and an EPHEMERAL /tmp snapshot that rolls the whole target back if the sync
-# CRASHES mid-write. PR2 adds a third, independent layer for the case neither
-# covers: a "successful" upgrade that a manifest/logic bug silently let touch an
-# operator file. That layer is a DURABLE, operator-scoped pre-update snapshot:
-#
-#   Part 1 (scope):      before any mutation, the installer copies exactly the
-#                        operator-owned files that exist into a retained backup
-#                        under $XDG_STATE_HOME/mosaic/backups/pre-update-<ts>/ —
-#                        framework files are NOT captured.
-#   Part 2 (perms):      the backup root, snapshot dir and every nested dir are
-#                        0700; every backed-up file is 0600 (never world-readable,
-#                        even though operator config may hold secrets).
-#   Part 3 (no leak):    a secret seeded into credentials.json is copied into the
-#                        snapshot (proving coverage) but its value never appears
-#                        on stdout/stderr — the snapshot reports counts/paths only.
-#   Part 4 (retention):  only the newest MOSAIC_BACKUP_RETENTION snapshots survive;
-#                        older ones are pruned.
-#   Part 5 (verify net): if the upgrade DID modify an operator file (injected here
-#                        with a cp shim that scribbles on SOUL.md while a framework
-#                        file is copied), the post-sync verify restores that file
-#                        from the durable snapshot and warns loudly. The control —
-#                        the same installer with the verify call stripped — leaves

-# `cp` writing THROUGH a symlinked destination. GNU/BSD cp — what a real operator

-# Alpine CI image) REPLACES a symlinked dest instead of following it, so under the
-# CI harness the leak vector simply does not exist and the negative control could
-# never reproduce it. This shim therefore emulates the real-target GNU cp behavior
-# PORTABLY: when the destination is a symlink it writes the source bytes through the
-# link via redirection (which follows symlinks on every coreutils, busybox included);
-# otherwise it delegates to the host's real cp unchanged. Both the shipped-case and
-# the negative control run through this identical shim, so the ONLY difference
-# between them remains the SYMLINK-LEAF-GUARD — the control stays load-bearing and
-# non-tautological. It does NOT touch install.sh (approved) or the real assertions:
-# with the guard present the symlinked leaf is dropped BEFORE this cp runs, so the
-# dest is a real file and the delegate path is taken exactly as on a GNU host.

-#
-# Proves that a keep-mode framework upgrade (the `mosaic update` path:
-# install.sh with MOSAIC_INSTALL_MODE=keep MOSAIC_SYNC_ONLY=1) touches NO path
-# outside the framework-owned manifest. Every operator-owned sentinel — including
-# a deliberately UNANTICIPATED one the manifest never names — must survive
-# byte-identical with an unchanged mtime (not even rewritten). Framework files
-# must still update, and a retired framework file inside a shipped subtree must
-# still be pruned. No operator secret value may appear in installer output.
-#
-# Keep mode is a SINGLE code path (sync_framework_keep, a manifest-driven cp
-# overlay + scoped prune — no rsync). The matrix still runs twice, once with
-# rsync on PATH and once with it hidden, to prove the keep path is genuinely
-# rsync-independent: it must obey the manifest identically whether or not rsync
-# happens to be installed (rsync --delete is only ever used by overwrite mode,
-# which has no operator state to protect).
-#
-# It also runs a fail-closed matrix (#791 B2/B3): an empty, operator-only,
-# malformed, or missing manifest must ABORT the upgrade loudly and leave every
-# operator path untouched — never silently no-op to "complete".

-# test-upgrade-rollback.sh — the #791 B1 regression gate.
-#
-# A keep-mode upgrade takes a pre-update snapshot and installs an ERR/INT/TERM
-# trap that restores it if the sync aborts midway (install.sh: make_snapshot +
-# `trap restore_snapshot`). That trap is only reached if `set -E` (errtrace) is
-# active — otherwise a failure INSIDE sync_framework_keep() (which runs entirely
-# in a function) never fires the trap, and the upgrade aborts leaving a
-# half-written target with NO rollback. This test proves:
-#
-#   Part A (the gate):   the shipped installer rolls back a mid-sync failure —
-#                        the restore message fires, the corrupted file is put
-#                        back, AND the whole target is byte-identical to its
-#                        pre-upgrade state.
-#   Part B (the control): the SAME installer with `-E` stripped does NOT roll back
-#                        (dead trap) — the mid-sync corruption survives, proving
-#                        errtrace is load-bearing. If anyone removes `set -E`,
-#                        Part A goes red.
-#
-# The mid-sync failure is injected with a PATH-shadowing `cp` shim rather than
-# file permissions. The earlier 0400/EACCES approach was NOT portable: Woodpecker
-# runs steps as root (node:24-alpine has no USER directive), and root overwrites a
-# 0400 file, so the failure never fired and this gate silently passed (#791
-# blocker-3). The shim fails deterministically for one framework-owned
-# destination regardless of uid, and — like a real interrupted cp (disk-full
-# mid-write) — leaves a partially-written target behind, so rollback has real
-# damage to undo and the control has real damage to expose.

-/**
- * P1 — Proxy preflight + lifecycle helpers for `mosaic yolo claudex`.
- *
- * Security-relevant invariants exercised here:
- *  - Liveness probe hits the proxy's dedicated `GET /healthz` and treats only a
- *    2xx as "alive" — a *proxy-specific* health contract, not arbitrary HTTP on
- *    the port (CWE-345: a local port-squatter must not be trusted as the proxy).
- *    This also honors spec gotcha #1 (never `curl -f` the root, which returns
- *    non-2xx): `/healthz` returns 2xx when the proxy is up, so a healthy proxy is
- *    never mistaken for dead and no duplicate proxy is spawned.
- *  - Auth-status parsing NEVER surfaces OAuth token material — only a coarse
- *    state + optional expiry — even if a token-shaped string appears in output.
- *  - The systemd unit's ExecStart never interpolates an unvalidated path
- *    (CWE-74: a CR/LF in the path could inject arbitrary systemd directives).
- *  - The nohup fallback captures spawn's *async* error event instead of crashing.
