-## Per-estate durable agent working memory (#1051)
-
-### Problem and objective
-
-Agent and lane continuity currently accumulates as plain local files with no repository backing. The installer must make a private, per-estate `mosaic-brain` clone at `~/.mosaic` reproducible without authorizing cross-estate access or introducing an independent credential path.
-
-### Normative requirements
-
-1. `MB-REQ-01` (R1): Ensure the target estate's existing `mosaic-brain` can be cloned to `~/.mosaic`; repository creation and live access granting remain broker-mediated.
-2. `MB-REQ-02` (R2/Q1): Derive estate and brain target from the configured target git host through the credential broker's estate registry. A second `brain_repo` authority and host-machine inference are forbidden; an unknown host fails closed with a named diagnosis.
-3. `MB-REQ-03` (R3): Seat access is granted only through `mosaic cred`; callers must never resolve or read a token independently. Live grant verification is gated on MC-CRED-01 implementation.
-4. `MB-REQ-04` (R4): The eventual live postcondition requires `~/.mosaic` to be a `main`-branch git repo with the expected remote and a seat-owned read/write round-trip. This live validation is gated on MC-CRED-01 implementation and cannot be replaced by a clone exit code.
-5. `MB-REQ-05` (R5): The out-of-estate refusal control covers both Git and API resolver axes. Axis disagreement is `indeterminate` failure, never permission; contract tests bind to the broker's four terminal classes and stable reason codes.
-6. `MB-REQ-06` (R6): The brain skeleton excludes `*.token`, `*.key`, `*.pem`, `.env`, and `credentials.json`; credentials remain broker-owned and no error path may print secret material. Arbitrary legacy content is never auto-published from a heuristic denylist: an approved content scanner must bind approval to the exact source snapshot, otherwise the item is retained and reported.
-7. `MB-REQ-07` (R7): Detect existing local lane directories and seat state files, publish approved snapshots into the durable layout without overwrite or deletion, and explicitly report every detected item that cannot be migrated. Automatic source deletion is parked until command-scoped identity propagation and the required clean audit; retained sources are always reported. Lane findings are append-only; `board/` has a named single writer; writes push immediately rather than on a timer.
-8. `MB-REQ-08` (R8): `mosaic doctor` reports missing clone, wrong remote, incomplete write-access evidence, and uncommitted local state. `--fix` repairs the first three only through the approved installer/broker path; it never hand-rolls credential resolution.
-9. `MB-REQ-09`: Retention is ownership-first and archive-only. Every retained artifact requires a named durable owner; absent or non-durable ownership leaves the gate open and blocking. Age and size never authorize deletion.
-10. `MB-REQ-10`: Brain provisioning occupies canonical installer P7 only after the applicable P5 credential postcondition commits; canonical phase numbers are unchanged.
-
-### Current delivery slice
-
-In scope now: estate derivation, secret exclusion, non-destructive migration, doctor reporting/repair orchestration, and red-first tests over all four credential-contract terminal classes. Live grant and live read/write round-trip evidence remain explicitly gated on the working MC-CRED-01 broker and must not be mocked or replaced by independent token lookup.
-
-### Acceptance criteria
-
-1. `AC-MB-01`: Contract tests observe RED before implementation and then distinguish `ok/0`, `refused/10`, `error/20`, and `indeterminate/30`, preserving v1.5 diagnoses including refused `provider-identity-mismatch`/`credential-rejected` and indeterminate `identity-not-measured`/`provider-unavailable`. A scope-forbidden `/user` result with confirmed in-scope repository capability is never represented as a dead credential. `identity-not-found` remains reserved for a future visibility-authorized inventory operation and is not an expected `validate` result.
-2. `AC-MB-02`: Estate resolution uses the configured target git host and one registry; unknown, mismatched, and host-machine-derived inputs fail closed.
-3. `AC-MB-03`: A clean fixture contains the required layout and exact secret exclusions; filename-, content-, binary-, and size-based secret controls remain outside Git without their values appearing in output. Without an approved scanner, even benign legacy content is retained and reported rather than auto-published.
-4. `AC-MB-04`: Migration publishes approved lane-durable and seat-state snapshots into collision-safe archive/ledger paths, retains and reports every source, never overwrites an existing finding, and never deletes by age/size.
-5. `AC-MB-05`: Doctor detects all four R8 defect classes; `--fix` repairs eligible classes through the approved P7/broker seam and leaves unresolved credential-dependent states visible.
-6. `AC-MB-06`: Git-axis and API-axis refusal must both be authoritative `refused` outcomes with matching stable reason codes; any disagreement yields `indeterminate`.
-7. `AC-MB-07`: Independent code review and security review pass at the exact head, and HOMELAB Woodpecker instance `mosaic` is terminal green before integration.
-8. `AC-MB-08`: After reviewed merge to `main`, report only **believed-fixed, pending jarvis validation**; issue #1051 remains open until W-jarvis validates the installed result.
-
-### Constraints and risks
-
-- MC-CRED-01 contract v1.5 is the caller boundary; no independent credential/token lookup is permitted. Identity is established from governed mint-time binding and provider evidence when measurable, never a credential filename. Runtime validation does not widen a least-privilege token merely to make `/user` observable.
-- C1 owns installer phase sequencing. This slice consumes P5/P7 ordering without renumbering or duplicating the phase machine.
-- Lane content is findings, so last-writer-wins is data loss. Append-only names and explicit collision handling are mandatory.
-- A created-but-empty brain beside unbacked local doctrine fails the objective; migration is a primary acceptance gate.

-

-- Intake base was HOMELAB provider `next` = `4df478cdd150fdf8d52ea109f02ade5d85017acd`; `main` = `5916aeefd6ed12bcac086c6834c7f6c4ae38e1bc`. On 2026-08-05 `mos-claude` ruled that L0 trunk-based gate 15 requires all three lanes to retarget to `main`; `next` remains a non-merging integration branch. Never weaken or patch `pr-merge.sh`.
-
-## Scope
-
-### In now
-
-- R2/Q1 target-host estate derivation using one registry.
-- R5 both-axis refusal parity and disagreement failure.
-- R6 exact secret exclusions and no secret-bearing diagnostics.
-- R7 detection plus non-destructive, collision-safe migration/reporting.
-- R8 doctor checks and approved-seam fix orchestration.
-- Red-first tests over all four contract terminal classes and stable reason codes.
-
-### Gated / excluded
-
-- R3 live grant: waits for working MC-CRED-01.
-- R4 live seat-owned read/write round-trip: waits for working MC-CRED-01.
-- No independent token lookup, grant helper, or shared-credential fallback.
-- No phase renumbering; C1 owns the phase machine and provides the P5→P7 seam.
-- No age/size reaping or deletion.
-
-## Owner authority ruling and resolver seam
-
-- Binding addendum: `/home/hermes/agent-work/tl-mosaic/CHARTER-MB-BRAIN-01-ADDENDUM.md`; re-read after compaction.
-- HOMELAB durable lane-archive owner and user-namespace brain owner are the human provider account selected by local estate policy (operator ruling: `jason.woltje`) with a required GLPI queue as the standing remediation process. The brain target is therefore `<policy-owner>/mosaic-brain` on the estate host, not `<installer-source-org>/mosaic-brain`. Framework source remains operator-agnostic: the actual login and queue are local policy, not hardcoded open-source context.
-- Provider lookup is anonymous because the ruled owner is public. It requires exact allowlisted login plus a same-invocation public known-good control, private 404 control, and generated absent 404 control. It sends no Authorization header and never widens token scope.
-- Provider `active` is deliberately ignored: non-admin reads return false for demonstrably active accounts. Resolvability + exact login + public visibility are the gate.
-- Private and absent principals both return anonymous 404. The fail-closed reason is `owner-not-resolvable`, never owner-not-found.
-- Caller `owner` strings and `validated=true` are ignored. Migration consumes only an injected source-of-truth resolver result. Owner grammar is NFKC-stable, ASCII allowlisted, exact-policy matched, and mission-seat class is excluded.
-
-## Plan
-
-1. Pre-register acceptance tests and observe each requirement RED for its own missing behavior.
-2. Commit the red tests before implementation.
-3. Implement a narrow brain provisioning/doctor helper that consumes broker JSON outcomes and the shared estate registry without credential resolution.
-4. Implement safe migration and exact brain skeleton/ignore policy.
-5. Integrate the helper into C1's P7 seam and `mosaic doctor` after C1 lands/rebase.
-6. Run focused, package, installer, lint, typecheck, format, and situational security tests.
-7. Run independent code and security reviews in parallel; remediate and re-review.
-8. Push after HOMELAB queue guard, open the reviewed PR to `main`, and preserve merge order C1 → MC-CRED → MB-BRAIN. Do not modify the merge guard; `next` is non-merging integration only.
-9. Re-take CI measurement at the rebased exact head; do not rework code solely because base evidence moved.
-
-## Acceptance interpretation registered before results
-
-- `ok/0`: complete authoritative evidence only.
-- `refused/10`: complete authoritative denial only.
-- `error/20`: local contract/control failure; never reinterpret as denial.
-- `indeterminate/30`: incomplete/disagreeing evidence; fail closed, never resolve permissively.
-- Both Git and API axes must return authoritative `refused` with the same stable reason code for R5. Any axis disagreement is `indeterminate`. A provider `/user` login mismatch is first-class `provider-identity-mismatch`; credential filenames never establish principal identity.
-- Migration publication requires the durable object to contain the approved snapshot and no overwrite. Automatic path-based source deletion is parked; every source is retained and reported.
-- Secret exclusion is tested through exact ignore rules, nested secret-shaped paths, bounded UTF-8 content controls, and an approved-scanner gate bound to the exact source snapshot. Without an approved scanner, even benign content is retained and reported rather than committed.
-
-## Budget
-
-No explicit token ceiling was supplied. Working cap: 55K tokens for implementation/review and 3 focused remediation attempts per failure class. Reduce optional refactoring and documentation breadth before touching required acceptance scope.
-
-## Risks
-
-- C1 and MC-CRED branches have not merged into `main`; integration edits must wait for their exact interfaces or be confined to stable contract seams.
-- A broker runtime test before MC-CRED lands would either fail for an irrelevant reason or pressure a hand-rolled workaround; contract fixtures are allowed, live capability claims are not.
-- Migration can lose data through overwrite, cross-device move failure, or partial copy. Implementation must stage, verify resulting bytes, and retain/report source on incomplete transfer.
-- `~/.mosaic` is a git repo, while current working state may live under multiple local roots; detection must be explicit and cannot treat age/size as ownership.
-
-## Progress / evidence
-
-- [x] Charter receipt accepted by `tl-mosaic`.
-- [x] Issue #1051 R1–R8 read directly from provider.
-- [x] Contract re-derived through v1.3, moving v1.4, and v1.5 before R5 integration. v1.5 separates in-scope repository capability from `/user` identity measurement: 401 is `credential-rejected`/refused, 403/404 may become `identity-not-measured` only after in-scope capability succeeds, and 200 login mismatch is refused. `identity-not-found` is not reachable from `validate`.
-- [x] C1 P5→P7 seam receipt read; no brain implementation is in C1.
-- [x] RED acceptance set committed at `cf11c6c86abae073d8b02b4014cd5447ba67f12a`; author and committer read back as `be-coder-07` and branch reachability was independently verified by `tl-mosaic`.
-- [x] Moving-contract REDs observed independently for v1.4 mismatch, R8 prerequisite ordering, owner resolver seam/allowlist, tracked skeleton/no-follow behavior, runtime observation/publication, and provider owner resolution.
-- [x] Focused implementation includes secure migration, v1.5 write-differential/subject binding, production Git+API refusal parity, provider-backed durable owner resolution that ignores non-admin `active`, required GLPI standing-process policy, P7 provision orchestration, an internal installer command, and installed `mosaic doctor` wiring. Latest focused result: 97/97 (secure config 4, store 45, runtime 19, owner resolver 16, provision 5, provision command 3, installed doctor 5).
-- [x] MC-CRED added the required canonical reverse registry seam `ParsedCredentialEstateRegistry.resolveByHost()` at dependency head `6ca8758f`; current local copies are temporary until dependency integration and the 32-line permissive shim has been removed.
-- [x] Identity gotcha measured: inline `MOSAIC_GIT_IDENTITY=be-coder-07` controls credential resolution but does not override `user.name`/`user.email` inherited from the linked worktree common-dir config (`coder-mos1`). The first local P7 RED commit was immediately amended before push with command-scoped `GIT_AUTHOR_*` + `GIT_COMMITTER_*`; resulting author and committer both read back as `be-coder-07`. Every subsequent authoring command must carry both identity sets and be verified.
-- [x] R6 migration reports filename- or content-secret-shaped files without copying them; arbitrary legacy content requires an approved scanner bound to the exact source snapshot, and production currently retains/reports when no approved scanner is configured. `.gitignore` is canonical allowlisted content only: an existing noncanonical regular file fails closed and is never merged into publication. Symlinked `.gitignore`, layout directories, and nested migration destinations fail closed; a dirty checkout blocks provisioning before skeleton publication. The brain root is principal-owned mode `0700` before clone and after clone, all memory-bearing layout directories are mode `0700` even under umask `0022`, and doctor reports owner-accessible roots as hard unsafe findings.
-- [x] Provider owner lookup uses manual redirect handling, a five-second abort signal, strict JSON content type/shape, and an incrementally enforced 256 KiB response ceiling.
-- [x] Security-critical owner policy/registry reads have direct controls for principal UID ownership, file/ancestor permissions, and descriptor-safe regular-file reads.
-- [x] Automatic source deletion is parked per the shared-Git-identity governance ruling; remotely reachable snapshots still leave and report every source.
-- [x] Multi-host push-on-write uses an isolated temporary Git index populated from approved in-memory blobs rather than pathname re-reads, verifies each committed blob ID, the exact changed-path allowlist, and both author/committer trailers before push, then reconciles only approved paths into the real checkout index. Real-repository controls prove a clean checkout remains clean, a concurrent non-fast-forward fetch/rebase/push remains clean and preserves both findings, destination-path substitution cannot change committed bytes, and unrelated pre-staged secret-shaped content remains staged but never enters the published commit.
-- [x] Doctor Git observations preserve three states: `clean`, `dirty`, and `unmeasurable`; failed remote, branch, or status measurements emit hard `brain-git-state-indeterminate` findings rather than mismatch or ready. The boolean-literal guard sweep covered all MB-BRAIN production files in the 20-file PR population: its only remaining `=== false` guard is the non-nullable `isAbsolute()` predicate; no nullable boolean measurement guards remain.
-- [x] Author-run Review 10 and focused 88/88 evidence were declared void when blocker fixes changed the head; neither is an independent gate pass.
-- [ ] Installer shell P7 invocation after C1 + MC-CRED integration; production command is registered but the C1 shell has not yet called it.
-- [ ] Implementation green on merged dependency base.
-- [ ] Independent code review.
-- [ ] Independent security review.
-- [ ] HOMELAB CI terminal green at exact head.
-- [ ] Reviewed PR retargeted to `main` after C1 and MC-CRED; `next` remains non-merging integration only.
