docs(remediation): precondition (3) rewritten — the field must be LIVE in the executing wrapper; merging #1066 is not sufficient (D-51's class inside the remedy)

Round-4 verdict id 73 (NO-GO @ fbb61912) landed 2026-08-01T18:12Z; remediation was pushed the same evening; the round-5 re-review dispatch was lost at the rotation seam and 'awaiting rev-974 verdict' was carried as fact for four days. Provider re-measured, round 5 dispatched (durable PR comment + verified tmux), board corrected. General form owned by Mos: a waiting-on-X state line decays like any other measurement and must be re-measured at rotation.

-## 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.

If the gate trusts a locally-writable ref, the anchor moved from the manifest into git config. |
+| **A2** | **Absent/stale target:** if `refs/remotes/origin/main` is missing, stale, or the fetch is shallow, does it fail CLOSED (line 57 suggests it does) or silently derive a narrower range?                                                                                                                                                                                    |

+## Framing — attack the FIX, not the original bug
+
+Every round on this mission, **the remediation introduced the next hole**: the commit-binding fix
+shipped a type confusion; the type-strict fix was clean but the registry around it had four defeats.
+So the highest-value checks here are **not** "was each blocker fixed" — the orchestrator already
+reproduced three of the four attacks as dead — but **"is the NEW mechanism itself defeatable?"**
+
+Blocker 1's fix replaced an author-settable field with a **derivation**. A derivation has inputs. **The
+question is who controls them.**

+# RM-02 / PR #1030 — PRE-REGISTERED RE-REVIEW: honest narrowing + (d)-strict
+
+**Subject head (exact):** `e910a45ab3578a9c77ad3eeaa52b31b72611f6c6`
+**Supersedes:** the third NO-GO at `fbb61912` (D-45/D-46/D-47) and the D-52 stop. Those are VOID.
+**Registered by:** `mos-remediation` before any reviewer read the diff. **Reviewer:** `rev-974`.
+
+## Already reproduced by the orchestrator (do not re-spend here)
+
+- The required narrowing sentence is **verbatim** in `gates/required-gates.baseline.json` and in
+  `scripts/gate-inventory-claim-control.mjs`: _"Detects accidental and incompetent inventory drift
+  within a checkout; does NOT survive an adversary who rewrites baseline, manifest, and verifier
+  consistently — that guarantee requires RM-60's external boundary."_
+- **The overclaim control FIRES**: clean ⇒ exit 0; injecting "protected, independently anchored" into
+  the baseline purpose ⇒ **exit 84**, `INVENTORY_CLAIM_OVERSTATED`.
+- CI #2201 at the exact head, 10/10 incl. `clone`; machine check bound, `exempted_steps 0`, no anomalies.
+
+## N — the narrowing (D-52's ruling is the wording)
+
+| id     | check                                                                                                                                                                                                                                                                                |
+| ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| **N1** | ★ Is the narrowed claim **honest EVERYWHERE**, or only where the control looks? Find any place — docs, comments, observations, manifest prose, CLI output — that still implies the baseline is protected or independently anchored. **The control only checks the files it checks.** |
+| **N2** | ★ Can the **overclaim control itself** be defeated? It is PR-controlled like everything else. Weaken/skip/reword it so an overstatement passes. If it can be trivially neutered, D-52 is re-armed one level down — the exact recursion this PR keeps producing.                      |
+| **N3** | Does the control detect **semantic** overclaim or only the literal strings it greps? An artifact could assert protection in different words and pass.                                                                                                                                |
+| **N4** | Is the narrowed claim **TRUE**? Verify the baseline genuinely catches accidental/inconsistent drift — not just that it says so. A narrowed claim that is still overstated is D-48 again.                                                                                             |

+| **H1** | Is the verifier **structurally incapable** of reporting history-provenance-verified, or merely not currently doing so? The manifest says "structurally incapable" — test the claim.                  |
+| **H2** | ★ **TRAP 1 re-check:** nothing emits the unverifiable state as an OBSERVATION (which exits 0). Confirm no path yields exit 0 while implying provenance was considered.                               |
+| **H3** | ★ **TRAP 2 re-check:** the exclusion is **enforced**, not merely declared in `coverageBoundary.excluded`. Re-enable history provenance without a trustworthy anchor — does a registered case go RED? |
+| **H4** | The residual is stated **correctly** — no local git state is trustworthy because PR code executes before the gate — **NOT** the D-48 wording ("compromised main").                                   |

+
+**Subject head (exact):** `83d2ecb2243f1b0987ef2bc14de47f444285a684`
+**Rebased onto:** `main` @ `f4fd5967fc5d4cbc72d680b199d88224aa855131` (post-RM-61)
+**Registered by:** `mos-remediation` **BEFORE the reviewer read the diff.** **Reviewer:** `rev-974`
+(author ≠ reviewer; branch commits are `f10-coder`'s and `coder-mos1`'s).
+**Prior reviews 63 / 65 are SUPERSEDED; this head carries NO live review of any kind.**
+
+RM-02 is the **keystone**: it is the anti-inert-gate registry every downstream gate is measured against.
+A defect that survives here propagates into every gate this mission ships.
+
+## ★ CRUX — the one non-mechanical change, made by the author, that turned a red green
+
+The rebase was clean. One further commit was **not** purely mechanical and the author disclosed it
+unprompted (`83d2ecb2` — advance registry activation seam):
+
+    gates/gates.manifest.json
+    -  "activationCommit": "f65e9ea656ec466e12640bf6ab5d46fe07ff160c"
+    +  "activationCommit": "f4fd5967fc5d4cbc72d680b199d88224aa855131"
+
+Stated rationale: after the rebase, `pnpm gate:verify` correctly failed because the newly-merged
+pre-registry RM-61 commit was treated as _prospective_ and required a manifest that could not exist.
+
+`activationCommit` sets the lower bound of `activationCommit..HEAD` — **the set of commits required to
+carry own-tree registry provenance** (`gate-history.mjs:314` → `listProspectiveCommits`). Advancing it
+**shrinks that set**.

If impossible, is advancing the seam the _correct_ remedy, or does a correct remedy exist that does not move an author-controlled field?                                                                                                                                                                                                                                |
+| **A2** | **Is the advance MINIMAL?** Was it advanced exactly to the new parent baseline, or beyond it? Does any commit that _should_ remain covered fall outside the new range?                                                                                                                                                                                                                                                                                                                                                                                |
+| **A3** | **Are all 7 branch commits still PROSPECTIVE under the new seam?** Enumerate them and show each is still required to carry provenance. The author claims "own-tree provenance over every registry-era branch commit" — verify the claim, do not accept it.                                                                                                                                                                                                                                                                                            |
+| **A4** | ★★ **IS THE SEAM ITSELF CONSTRAINED?** The only validation found is `merge-base --is-ancestor activationCommit head` (`gate-history.mjs:288`). **A commit is its own ancestor.** Determine what `activationCommit = HEAD` does: is the prospective range empty, does the per-commit loop iterate zero times, and does the history check therefore PASS VACUOUSLY? If so, the anti-inert-gate registry contains an author-settable field that can inert its own history check. **Run it. Report the observed exit and whether any failure is raised.** |
+| **A5** | **If A4 shows vacuity is reachable, is there a registered MUST-FAIL negative control for it?** RM-02's own founding rule is that a gate with no proven failure path manufactures evidence. Does the registry hold a case that goes RED when the seam is over-advanced? If not, that is a hole in the registry's coverage of itself.                                                                                                                                                                                                                   |
+| **A6** | **Self-verification shape (charter / D-19 / D-39b):** the field was advanced by the change's own author to make the author's gate pass. Independent of whether the value is correct, determine whether the _mechanism_ permits an audited party to relax its own audit, and whether that needs a constraint, an owner, or an escalation.                                                                                                                                                                                                              |

+| **B1** | **D-38 clause present and enforced:** the registry asks of every gate _"does this gate BIND its evidence to the subject under review?"_ Ruled in-scope for THIS PR by Mos. Verify it exists as a checked clause, not prose.                                             |
+| **B2** | **D-40 clause present and enforced:** _"discriminator and comparison inputs must be TYPE-STRICT."_ Also ruled in-scope for THIS PR. `== 0` matching `False`/`0.0` is the banked instance; the clause is the general form.                                               |
+| **B3** | **D-42's clause is CORRECTLY ABSENT** — provider-side negative control tracks separately (Mos: landing it now would give the registry a clause with nothing to satisfy it, going red on its own clause). Confirm its absence is deliberate and recorded, not forgotten. |
+| **B4** | **The four founding clauses still hold** (`MISSION.md`): every check proven **right** (red for its own stated reason), the set **covers**, no two criteria **conflict**, and criterion evolution **retains original text + restatement + reason**.                      |
+| **B5** | **Nothing was weakened, skipped, or deleted by the rebase.** Diff `f9746b23` → `83d2ecb2` and confirm no registered case, test, or assertion was removed or relaxed to make the rebase land.                                                                            |
+| **B6** | **`coverageBoundary.excluded[]` is honest in BOTH directions** (charter principle 4): what it does NOT cover is stated beside what it DOES, and the gap is tracked (`trackedBy: RM-54`) rather than implied-fixed.                                                      |
+| **B7** | **The RM-02 execution boundary** (`gate-history.mjs`, DOES / DOES NOT, owner RM-60, xref RM-59) states its limits in both directions and names a tracked owner — not a documented gap with no owner.                                                                    |

+# RM-03 / PR #1032 — PRE-REGISTERED RE-REVIEW (post-freshening)
+
+**Subject head (exact):** `868b9b871a5118762aa5b8aafecd2f0592f7ab5c`
+**Rebased onto:** `main` @ `f4fd5967` **Registered by:** `mos-remediation` before the reviewer read the
+diff. **Reviewer:** `rev-974`.
+
+**Why this exists:** review 66 APPROVED and the merge-gate GO were bound to `78ec47cd`; `main` drifted
+under a long hold and the PR went `mergeable=false` (**D-50 — a GO has a shelf life**). Both verdicts
+are VOID at the new head. Jason's merge approval is **standing** and executes once this re-gates.
+
+## What the orchestrator already verified (do not re-spend here)
+
+- `git range-diff 78ec47cd...868b9b87`: commits **2–5 are `=` (patch-equivalent)**; only commit 1 differs.
+- That single difference is the `test:framework-shell` chain, resolved as a **UNION** — main's
+  `test-terminal-green-contract.sh` **and** RM-03's `tristate`, `github-checks`, `merge-queue-branch`,
+  `merge-head-pin`, plus the pre-existing `branch-absent`. **Nothing dropped from either side.**
+- CI #2199 at the exact head: 9 children, 9 success incl. `clone`; machine check exit 0, bound, no anomalies.
+- `mergeable` is now **true**.

+| **R1** | ★ **THE GUARD CAN FAIL.** RM-03 exists because the queue guard is ZERO-INFORMATION (D-23) — it returns pass for every possible input. Prove the rebased head's guard **actually fails** on asserted non-readiness, not merely that its tests pass. This is the whole deliverable. |
+| **R2** | ★ **NO QUEUE-GUARD SEMANTIC MOVED IN THE REBASE.** Confirm the range-diff equivalence independently. A queue-guard semantic resolved quietly re-breaks the thing this PR fixes.                                                                                                   |
+| **R3** | **Union is complete in BOTH directions:** no RM-03 suite lost to main's version, no main suite (esp. `test-terminal-green-contract.sh`) lost to RM-03's. Enumeration count reconciles.                                                                                            |
+| **R4** | **Tri-state is real** (`verified` / `written-unverified` / `failed`) — P-WRAPPER-001. Verify an indeterminate result cannot present as a pass; that is the exact defect (`state=unknown exit 0`).                                                                                 |
+| **R5** | The guard's **exit-asserting non-null-case** tests are genuine — each fails for its own stated reason against pre-fix code, not merely present (D-8).                                                                                                                             |
+| **R6** | `test:framework-shell` is **runnable to completion in CI** (canonical env). Known: it exits 97 on some hosts via a Bash 5.2.15 `BASH_LINENO` assertion — if you hit that, report it as an environment limitation, do not treat it as a finding and do not let it mask one.        |
+| **R7** | Exact-head CI terminal-green, full `-f json`, counts stated incl. `clone`; machine-checked with `--expect-commit 868b9b871a5118762aa5b8aafecd2f0592f7ab5c`.                                                                                                                       |

+# RM-61 / PR #1033 — PRE-REGISTERED RE-REVIEW ACCEPTANCE CHECKS
+
+**Subject head (exact):** `033b2ffb46674b2c0bcc5197273c109b461f62d9`
+**Supersedes:** review 67 / comment 20403 @ `e7b29219` (NO GO). That verdict is VOID — the head moved.
+**Registered by:** `mos-remediation` (orchestrator). **Reviewer:** `rev-974` (author ≠ reviewer).
+**Registered BEFORE the reviewer read the diff.** Any head move after this file is committed voids the
+re-review and requires re-registration.
+
+## Scope discipline
+
+The prior review passed AC1–AC8 and still found a blocker, because the registered set tested whether the
+signature DISCRIMINATES and never tested whether the evidence was BOUND TO ITS SUBJECT (Finding 3 /
+coverage-failure-mode-2, D-17 class). This set therefore carries the binding property as a first-class
+check, and **RR7 explicitly invites the reviewer to attack outside the set** — a registered set is
+protection against retrofitting only, never a ceiling on scrutiny.

+# RM-61 / PR #1033 — PRE-REGISTERED ACCEPTANCE CHECKS: `exit_code` TYPE-STRICTNESS (D-40)
+
+**Registered by:** `mos-remediation` (orchestrator) — **BEFORE the fix was pushed and before any
+reviewer read a diff.** At registration time the fix existed only as an unpushed local commit
+(`6e7a336d`) on coder-mos1's machine which **I have not read**. There is therefore no diff for these
+checks to have been retrofitted to.
+
+**Subject head:** TBD — binds to the NEW head once coder-mos1 pushes. The prior head
+`033b2ffb46674b2c0bcc5197273c109b461f62d9` and its review 69 / pipeline #2193 go VOID on that push;
+that cost was accepted deliberately by Mos's BLOCKING ruling on D-40.
+
+**Ruling being enforced (Mos, 2026-08-01):** `exit_code` must be accepted ONLY as a real integer.
+`false`, `0.0`, `"0"`, and `null` must all fail to satisfy the exemption. Wrong-ACCEPT is the
+disqualifying direction; this hole sits inside the load-bearing discriminator.
+
+## ⚠ Read this before writing the tests — RED-FIRST HERE IS NOT UNIFORM
+
+Two of the four near-miss values **already block** at `033b2ffb`. Demanding "all four observed RED
+first" would be demanding an impossible red for two of them, and the predictable response to an
+impossible demand is a fudge — weakening something real to manufacture the red. So state it precisely:
+
+| value   | behaviour at `033b2ffb` (pre-fix) | what the new case is      |
+| ------- | --------------------------------- | ------------------------- |
+| `false` | **WRONGLY EXEMPTS** (exit 0)      | **genuine RED-FIRST**     |
+| `0.0`   | **WRONGLY EXEMPTS** (exit 0)      | **genuine RED-FIRST**     |
+| `"0"`   | correctly blocks (exit 1)         | **regression guard** only |
+| `null`  | correctly blocks (exit 1)         | **regression guard** only |
+
+Claiming red-first for `"0"` or `null` would be a false claim about your own evidence. Say which is
+which. **Do not weaken anything to make a green case go red** (D-8).

Hard requirement on RM-02: the registry must self-verify that every registered case runs AND can fail — presence is not evidence.

+**Phase:** EXECUTING — **RM-02 keystone is the front**.
+**Updated:** 2026-08-05 — successor seat live. D-56 state correction applied (lost round-5 dispatch,

 ## Head
 
-- Mission charter + 15 decisions + 4-build plan: PERSISTED (`docs/remediation/MISSION.md`).
-- HOLD lifted for this workstream (Jason 2026-07-31). Nothing implemented yet — planning first.
-- Orchestrator seat `mos-remediation` is LIVE and owns the mission. Residency attestation: PASS.
-- **TASK-0 DONE** — checkout repaired, all three gates green HONESTLY (no `--no-verify`), branch pushed.
-- **TASK-1 DONE** — both planners delivered independently on clean context; reconciled into `TASKS.md`
-  (58 tasks across P0–P5, 7 convergences, 7 adjudicated disagreements, 3 escalated decisions).
-- **NEXT ACTION IS NOT MINE:** DECISION-1/2/3 (`TASKS.md` §5) must be ruled before P0 dispatch.
-  RM-01 is dispatchable immediately regardless — it depends on nothing and blocks everything.
+- Charter + 15 decisions + 4-build plan: `MISSION.md`. Backlog + all findings: `TASKS.md`.
+- Planning DONE (58 tasks, P0–P5). **DECISION-1/2/3 all RULED by Mos 2026-07-31** (`TASKS.md` §5) —
+  nothing is waiting on a decision. D-2's availability _target_ is Jason-pending and non-blocking.
+- **Executing, not planning.** RM-01 is MERGED; three lanes are live (see In-flight).
+- Orchestrator seat `mos-remediation` LIVE, owns the mission, resumed across the rotation seam
+  2026-08-01 and re-attested to Mos from the files. Residency attestation: PASS.

+### For the incoming orchestrator — read this before acting
+
+1. **Lane state lives in the In-flight table above — this item does NOT restate it.** It went stale
+   three times in one session by duplicating that table (D-26's class). Read the table. ⚠ **And
+   re-derive any board claim from the provider before load-bearing use (D-43)** — the board is
+   sole-written and has no independent verifier.
+2. **`docs/remediation/TASKS.md` is authoritative**, not the newest voice in a chat. It holds 58 findings
+   (D-1…D-6 in `BOARD-LEDGER.md`, D-7…D-55c + D-38c in TASKS.md), every ruling with its rationale, and the
+   requirements each finding placed on RM-02/RM-34/RM-50/RM-55.
+3. **`MISSION.md` carries the first-class principles** — read them there, they are not listed here.
+   Two added 2026-08-01: **the anchor must live outside the audited party's authority** (D-19/D-25/D-45,
+   third arrival) and **no universally-quantified check may pass over an empty set** (D-44/D-46).
+4. **Seat identity:** `export MOSAIC_GIT_IDENTITY=<seat>` is stripped by a context reset (**D-34**) —
+   every dispatch/rehydration brief must re-export it, or the seat cannot use its credentials.
+5. **Scan CI from `-f json`, never default text** — text mode omits `clone` (**D-33**). State counts.
+6. **The queue guard is zero-information until RM-03 merges** (**D-23**) — never cite its green.
+7. **The bounded CI re-roll used on RM-02 was a one-time stopgap, NOT policy.** A per-PR free re-roll is
+   D-21 normalisation. Do not repeat it; RM-61 is the fix.

 ## Gate status

+- Git identity: orchestrator runs `MOSAIC_GIT_IDENTITY=mos-dt-0` INTERIM. Mos ruled gate-16 HOLDS (author≠reviewer is what
   gate-16 protects; rev-974 reviews, mos-dt-0 never self-reviews). Dedicated identity TRACKED, Mos provisions.
-- Capability check (D-11b): before dispatching seat X to provider Y, verify
-  `~/.config/mosaic/secrets/gitea-tokens/gitea-<Y>-<X>.token` exists. Token-file set = authoritative
-  capability registry. Mos owns provisioning; escalate missing pairs to him.
-- Seat identity (D-11a): token identity AND `git config user.name`/`user.email` must BOTH be set and
-  agree. Exporting `MOSAIC_GIT_IDENTITY` alone does NOT fix commit authorship.
-- Standing worker-brief doctrine (accreted, mandatory in every brief): don't weaken a RED test to make
-  it pass; if a check is unrunnable as written SAY SO, never silently substitute; `agent-send -f` never
-  `-m`; heavy artifacts off shared `/tmp`.
+- Capability + seat identity (**D-11b / D-11a**, incl. the false-NEGATIVE twin): authoritative in
+  `TASKS.md`. Short form — **assert the DIFFERENTIAL as that seat** (authenticated `push:true` vs
+  unauthenticated `push:false`); a single endpoint can be true for anyone or 403 for an unrelated
+  scope. Full text rolled to [`BOARD-LEDGER.md`](./BOARD-LEDGER.md).
+- ⚠ **LIVE HAZARD (D-37) — one shared `.git/config` re-identifies EVERY worktree at once.** Every seat,
+  including `rev-974`'s review worktree, currently authors as **`coder-mos1`**; `MOSAIC_GIT_IDENTITY`
+  does **not** override it. **STANDING ORDER: commit with explicit
+  `git -c user.name=<seat> -c user.email=<seat>@…`, and NOBODY rewrites the shared config mid-flight.**
+  Real fix authorised, Mos owns it, sequenced at a quiet seam. **#1024 implicated.** Detail: D-37.
+- Standing worker-brief doctrine (mandatory in EVERY brief): re-export `MOSAIC_GIT_IDENTITY` (**D-34**);
+  commit early/WIP (**D-31**); don't weaken a RED test to pass; if a check is unrunnable SAY SO, never
+  substitute; `agent-send -f` never `-m`; artifacts off shared `/tmp`; scan CI from `-f json` (**D-33**);
+  **relay observations into an open review, NEVER your own conclusion on an open check (D-39)**; the
+  **author never adjudicates their own PR's blocker status** — surface evidence, prepare the fix, hold.
 - Remote control: native `/remote-control` NOT wired in this runtime. Path is **Mos-relay**
   (Jason ↔ mos-claude via Discord ↔ mos-remediation via agent-send). Not a blocker.

-### **D-8 / P-CONFORMANCE-001 — a PRE-REGISTERED acceptance check that was not runnable as written.**
-
-PR #1025 AC2's fixture `mkdir -p apps/*/venv/lib` creates a literal `apps/*/venv/lib` dir when the glob is unmatched — it did not test what it claimed. rev-974 ran it exactly as written, caught it, re-ran the intended assertion at an explicit path, and **disclosed** rather than silently substituting a working fixture and reporting PASS. **Pre-registration protects a check from being retrofitted to the implementation; it does not make the check correct.** An unverified gate appeared inside the mechanism built to catch unverified gates. Hard requirement on RM-02: the registry must self-verify that every registered case runs AND can fail — presence is not evidence.
-
-### **D-7 / P-FLEET-001 — stale-GC-on-disk: shared 30G /tmp hit 100% ENOSPC, degrading two seats.**
-
-~5.2G was session scratch dead 8-9 days (this session's own footprint: 88K). Same missing capability as orphaned-tmux-session GC, applied to disk — not a quota or discipline problem. Resolved manually by Mos (lead coordinator) after independent verification; `/tmp` now 79%. **The gap IS the finding:** the authority to reap exists, the deterministic reaper does not. Folded into RM-50 with explicit requirements (mechanical liveness, age threshold, dry-run, audit event per reap — never a heuristic sweep). Refusing to unilaterally delete another session's scratch was correct doctrine; the fix is a reaper, not braver agents.
-
-### **D-6 / P-QUEUE-001 — the mandated queue guard returned PASS on an UNKNOWN state, live, today.**
-
-Running the required `ci-queue-wait.sh --purpose push` before pushing produced `state=unknown ... exit 0` — the exact defect at `ci-queue-wait.sh:282-288` that PR #1023 is parked on. It also evaluated `branch=main` rather than the branch being pushed. The mission's own required pre-push gate passed me on an indeterminate result. Third independent live instance of the class.

-- 2026-07-31 — Mission set up by Mos post-postmortem (15/15 decided). Dogfood posture active.
-- 2026-07-31 — Mos: stale `.mosaic/orchestrator/mission.json` is RESIDUE of the disabled Python
-  orchestrator rail that this plan RETIRES. Do NOT invest in it; do NOT build on that rail. The 0/0
-  milestone banner is cosmetic. (Supersedes any plan to repair it.)
-- 2026-07-31 — Mos: planners must be dispatched with GUARANTEED clean context, not requested-clean.
-  Prior default-socket planner sessions predate this mission; dirty context is the indicted hygiene.
-- 2026-07-31 — mos-remediation: worker briefs forbid all git ops and restrict each worker to a single
-  named output file, so two planners can share one checkout without a branch race (M2-era incident doctrine).

+> `gates`, `proseClaims`, `compatibilityScenarios` all `[]` — emptied the **registry population**
+> (D-46), each yielding **exit 0**. The first was fixed **as an instance**; the principle was never
+> extracted, **so it returned one level up.**
+>
+> **Delete every gate and every criterion TOGETHER and no remaining reference complains — because every
+> reference went with them.** A check that quantifies over a population must actually **range** over it,
+> and that population must be **provably complete and non-empty**.
+>
+> **Corollary (same disease):** a clause written for the instance that produced it is not a clause.
+> **Do not relabel the originating instances as the general clauses** — quantify over the population.
+
+### First-class principle — redundant observation on evidence-bearing steps
+
+> **Two observers of the same evidence, disagreeing, catch what neither catches alone.** Apply redundancy
+> not only to judgement calls but to **evidence gathering itself** — the step everyone assumes is
+> mechanical and therefore skips.
+>
+> Promoted by Mos (2026-08-01) from **D-33**. A seat scanned a pipeline with `-f json` and reported 9
+> steps; the orchestrator scanned the same pipeline in the wrapper's default text mode and reported 8.
+> **The default output omits `clone`.** Every "full step scan" that night had been 8-of-9 and was stated
+> as complete in good faith. No verdict changed — but the _method_ was wrong, invisibly, and **only the
+> disagreement between two counts surfaced it.**
+>
+> The reason it survived: **a summary that resembles an enumeration is more dangerous than one that
+> obviously summarises.** A labelled list of named steps with states _looks_ like the artifact, so nobody
+> checks it against the record. Compare D-24 — `mergeable` was a _true answer to a different question_;
+> this was a _true answer to a smaller one_. Neither is a lie; both pass every sniff test.
+>
+> **Operationally:** where a step _produces evidence a decision rests on_, have it produced twice by
+> different means, and treat **any divergence as a finding rather than as noise to reconcile**. Prefer the
+> machine-readable record over the human-readable rendering — _read the artifact, not the summary_ — and
+> state the counts observed so a divergence is detectable at all.

+the layer that needed it — and both times the only resolution was an authority _outside_ the audited
+party's control, which is precisely what Builds 1–2 provide.

+
+And to one consequence: **the anchor must live outside the audited party's authority.** A local check
+cannot defend against an actor who can rewrite the check; a repo cannot grant a capability to
+PR-controlled config and simultaneously prevent that config from using it.
+
+**An architecture forced by two independent impossibility proofs is stronger evidence than one argued
+for.** Neither proof was sought — both arrived while trying to ship something else, from different
+directions (a symlink manifest; a CI sandbox), at different layers. RM-59 and RM-60 are the two tracked
+dependencies this creates, and they are the same dependency in different clothes.

-# RM-61 — CI contract exemption for #1000 teardown artifact
-
-**Tracking:** RM-61 / issue #1000
-
-**Branch:** `fix/rm-61-ci-contract-exemption`
-**Owner:** `coder-mos1`
-
-## Objective
-
-Determine, by red-first provider controls, whether the `ci-postgres` pod-not-found teardown signature discriminates from a real PostgreSQL failure. Only if it discriminates may a named, bounded CI-contract exemption be implemented. The exemption must retire when #1000 is fixed; fixing #1000 is the closure path.
-
-## Pre-registered kill criterion
-
-If an injected real `ci-postgres` failure also yields `pods "wp-svc-<ULID>-ci-postgres" not found` as the service's provider-visible failure, the signature does not discriminate. Option B is unsafe; stop exemption implementation and fall to Option A (#1000).
-
-## Plan
-
-1. Capture full `-f json` records for the 11 supplied observations and state counts.
-2. Run one startup-failure control using the real pgvector/PostgreSQL image with an invalid `initdb` argument.
-3. Run one post-readiness crash control using real PostgreSQL, `pg_isready`, and a deliberate postmaster kill while a DB-dependent probe is active.
-4. Compare the raw `ci-postgres` service record independently of failures in dependent steps.
-5. Investigate runner/time/head clustering only as a hypothesis; never encode incidental correlates or retries into policy.
-6. If and only if the controls discriminate, implement and test the exact exemption, document its two-way boundary, and track retirement at #1000.
-
-## Budget
-
-No explicit token cap supplied. Working estimate: 20K–30K tokens. Limit provider controls to the two pre-registered runs; no retries or re-roll policy.
-
-## Initial evidence
-
-Historical JSON saved locally under `.evidence/rm-61/` (not for commit). Supplied pipelines: 11 total. Child-step counts: five pipelines with 9 children and six with 10 children. Seven contain the `ci-postgres` pod-not-found failure (#2170, #2175, #2180, #2181, #2182, #2187, #2188); four do not (#2158, #2167, #2184, #2186). Every observed workflow reports `agent_id=44`, so the available JSON does not separate clean and artifact runs by runner. This refutes runner identity as a discriminator in the sampled record.
-
-## Progress
-
-- [x] Requirements and kill criterion recorded before control implementation.
-- [x] Historical full-JSON records captured.
-- [x] Startup-failure control observed terminal.
-- [x] Post-readiness crash control observed terminal.
-- [x] Discrimination verdict recorded: Option B may proceed.
-- [x] Conditional exemption implementation.
-
-## Tests / evidence
-
-### Control 1 — real startup failure
-
-- Commit: `3931b0e29eb834914f7b17e4db7e221481d436fa`
-- Pipeline: #2189, exact commit match.
-- Full JSON child scan: 9 total — 7 success, 2 failure, 0 skipped/pending/running.
-- `ci-postgres`: `state=failure`, `exit_code=1`, `error=null`, with a five-second execution window.
-- `test`: `state=failure`, `exit_code=1` after the readiness budget expired.
-- Pipeline/workflow: terminal `failure`.
-
-This control is red and its service record differs from #1000 (`exit_code=0` plus pod-not-found). It proves the startup-failure direction only. It does not settle the dangerous post-readiness crash/garbage-collection path.
-
-### Control 2 — real post-readiness crash
-
-- Commit: `25ac59715a94dd1b52ef42577472eb44ecc4b446`
-- Pipeline: #2191, exact commit match.
-- Full JSON child scan: 9 total — 7 success, 2 failure, 0 skipped/pending/running.
-- Service log proves PostgreSQL reached `database system is ready to accept connections`, the test created the arm table, and the service then killed postmaster PID 7.
-- Test log proves a successful `SELECT 1` followed by `Connection refused`; it exited the pre-registered control code 61.
-- `ci-postgres`: `state=failure`, `exit_code=137`, `error=null`, with a 203-second execution window.
-- `test`: `state=failure`, `exit_code=61`.
-- Pipeline/workflow: terminal `failure`.
-
-This is the dangerous post-readiness crash path. Its service record is not pod-not-found and therefore differs from #1000 independently of the dependent test failure.
-
-### Discrimination verdict
-
-Both real failures are provider-visible as process exits (`exit_code=1` startup; `exit_code=137` crash) with no pod-not-found error. The seven observed #1000 artifacts are provider reconciliation misses (`exit_code=0` plus the exact pod-not-found error). The declared kill criterion did not fire, so Option B may proceed with a matcher requiring the full conjunction. This evidence does **not** prove every future Kubernetes failure is distinguishable; it proves these two concrete real-failure classes remain blocking and bounds the exemption to the observed reconciliation shape.
-
-### Unit red-first checkpoint
-
-The nine-case contract harness was written before the verifier. First execution exited 1 because `verify-terminal-green.py` did not exist; no exemption implementation was live. Cases pre-register ordinary green, the exact artifact, both provider controls, near-miss signatures, an independent failure, and a skipped step.
-
-### Control 2 setup attempt — invalid, excluded from evidence
-
-- Commit: `9455cd6a2650b2b7e70f746c07933d96e5cb3d20`
-- Pipeline: #2190, exact commit match.
-- Full JSON child scan: 9 total — 7 success, 2 failure, 0 skipped/pending/running.
-- Service log: `/bin/sh: 0: -c requires an argument`.
-- Root cause: Woodpecker service `commands` did not become the third `sh -c` argument. PostgreSQL never started, so this run is **not** the post-readiness crash control and provides no discrimination evidence.
-- Focused remediation: place the script directly in the third `entrypoint` element and supply `PGPASSWORD` for the marker query. This is a control-fixture correction, not a retry of #1000 and not evidence for either verdict.
-
-## Implementation evidence
-
-- `verify-terminal-green.py` consumes only the full JSON/API record; it performs no fetch, retry, or trigger.
-- Exact #2188 record: exit 0, 10 children, 9 success + 1 named exemption.
-- Historical set: #2158/#2167/#2184/#2186 pass with no exemption; #2170/#2175/#2182/#2187/#2188 pass with one named exemption; #2180/#2181 remain red because independent failures exist.
-- Provider controls: #2189 and #2191 both exit 1 under the verifier; neither is exempted.
-- Unit harness: initial 9/9 cases passed after the red-first checkpoint; review remediation expands this to 12 cases with expected-head match/missing/mismatch coverage.
-- Test-membership guard: PASS, population 45; 26 enumerated, 19 signed exclusions; all 39 surface paths present.
-- Python compile: PASS.
-- `pnpm typecheck`: PASS, 45/45 tasks.
-- `pnpm lint`: PASS, 25/25 tasks.
-- `pnpm format:check`: PASS after moving local evidence outside the repository tree.
-- `test:framework-shell`: RM-61 and all preceding suites passed, then the pre-existing wake assertion aborted with exit 97 because this host's Bash 5.2.15 reports `BASH_LINENO [3 5]` where that suite requires `[3 4]`. RM-61 does not modify the wake suite; the command is not fully runnable on this host as written and no substitute result is claimed.
-
-## Independent review
-
-- Review 67 / comment 20403 at exact head `e7b29219e11efd0a19395156ac0b154bec0c3a73`: **REQUEST CHANGES**.
-- Blocker: the verifier echoed the pipeline commit but did not bind it to the current PR head; mutating only #2188's commit still returned terminal-green.
-- Remediation: require `--expect-commit <full-40>`, add a pipeline anomaly on missing/mismatched record commits, emit expected and observed values, wire both CI documentation and the merge-gate baseline to pass provider PR head, and add match/missing/mismatch tests.
-- This binding is not prohibited head-based clustering policy: it proves the evidence belongs to the commit under verdict. Runner/node/time/head correlation remains excluded from the teardown signature itself.
-- Review 69 later approved the commit-binding remediation at exact head `033b2ffb46674b2c0bcc5197273c109b461f62d9`; pipeline #2193 was 9/9 success. Before merge-gate, an independent adjudicator found that Python treats JSON `false == 0`, allowing a non-integer exit value to match. The prior gate-ready state was withdrawn. The type-strict set distinguishes genuine red-first controls (`false`, `0.0`, which wrongly exempted) from regression guards (`true`, `"0"`, `null`, which already blocked). Remediation requires the decoded type to be exactly `int` and excludes `bool` explicitly.
-
-## Documentation checklist
-
-- [x] CI contract documented in the canonical framework CI/CD guide.
-- [x] Operator command documented in the Woodpecker tool README.
-- [x] Merge-gate baseline points to the deterministic verifier and named retirement.
-- [x] Tracking and retirement cite issue #1000.
-- [x] Both positive and negative guarantee boundaries are stated.
-- [x] No API/auth/schema/user-facing navigation change; OpenAPI, user guide, and sitemap are not applicable.
-
-## Risks
-
-The controls establish discrimination for deterministic startup failure and an armed post-readiness postmaster crash on the current Woodpecker Kubernetes provider. They cannot prove that every future Kubernetes failure mode will preserve a non-zero exit before reconciliation. The exact matcher minimizes that residual risk, and issue #1000 remains the mandatory provider-seam closure and retirement trigger.

-# #1019 — Zero-timeout queue-guard harness race
-
-- **Issue:** #1019 (parent status remains `believed-fixed, pending jarvis validation`; do not close)
-- **Branch:** `fix/1019-ci-queue-timeout-harness`
-- **Owner:** `be-coder-08`
-- **Base:** `origin/main` at `5916aeefd6ed12bcac086c6834c7f6c4ae38e1bc`
-- **Charter:** `/home/hermes/agent-work/tl-mosaic/CHARTER-1019-HARNESS-FIX.md`
-
-## Objective
-
-Make `test-ci-queue-wait-tristate.sh` deterministic without changing any asserted outcome. Remove the indiscriminate zero-timeout race, require every status-classification case to prove the provider was observed, and prove the harness-controlled virtual clock is active.
-
-## Scope
-
-- In scope: `packages/mosaic/framework/tools/git/test-ci-queue-wait-tristate.sh` only, plus this evidence scratchpad.
-- Out of scope: guard parsers, D2/D3 behavior, installer/reseed staleness, PR #1060, and issue closure.
-
-## Acceptance criteria
-
-1. RED deterministically reproduces deadline pre-emption before the provider call.
-2. Every case that intends status classification positively proves provider observation.
-3. Pending observes `pending` before deterministic virtual-time expiration.
-4. The virtual clock has a positive interception control; a broken-clock mutant makes the suite red.
-5. The exact CI-base image passes the final harness repeatedly with zero failures.
-6. Baseline gates, independent code/security review, exact-head CI, and coordinator-authorized squash merge pass.
-
-## Plan
-
-1. Add deterministic RED instrumentation for the known merge/provider-unreachable pre-emption.
-2. Replace global `-t 0` with a nonzero timeout interpreted under an event-driven virtual clock; stub sleep without wall waiting.
-3. Add provider-observation and virtual-clock positive controls without changing outcome assertions.
-4. Run focused shell checks, repeat in exact CI-base image, baseline gates, and independent reviews.
-5. Commit with both identity layers, queue-guard plus direct Woodpecker terminal-state verification, push, self-post PR, verify poster/head/CI, obtain coordinator merge authorization, then squash merge without closing #1019.
-
-## Budget
-
-- No explicit token cap supplied. Keep scope to one harness file and one scratchpad; stop/report at the charter's 60% context gate.
-
-## Evidence
-
-- RED, deterministic pre-provider expiry: `evidence/1019-harness-fix/red-pre-provider-expiry.log` — rc 1; merge/provider-unreachable got rc 124 instead of 75, omitted CANNOT_ASSERT, did not observe the status provider, and wrote no additional audit record (four named failures).
-- GREEN host focused harness: `evidence/1019-harness-fix/green-host.log` — rc 0, all outcome classes passed.
-- Load-bearing clock negative control: a temporary same-directory mutant replaced the virtual `date` body with `/bin/date`; `evidence/1019-harness-fix/red-clock-not-intercepted.log` — rc 1 with named `virtual clock interception did not run` failures. The mutant file was removed after the run.
-- Exact CI-base repeat: `git.mosaicstack.dev/mosaicstack/stack/ci-base:latest`, repository mounted read-only, harness work under container `/tmp`; `evidence/1019-harness-fix/ci-image-repeat/summary.log` — **100 pass / 0 fail / 100 total**.
-- Synchronization design: provider-status observation creates the event marker; virtual time is 1000 before the event and 1002 afterward. Pending alone reaches the stubbed no-op sleep and a post-observation deadline check. `-t 1` is uniquely load-bearing because removing it restores the 900-second default deadline at virtual time 1900, which 1002 does not cross. The numeric timeout is subject semantics under virtual time, not a wall-clock synchronization duration.
-
-## Review remediation — semantic timeout vs. liveness bound
-
-Security review found that virtual time remained at 1000 forever before provider observation and stubbed sleep never waited. A regression looping before the status endpoint—or blocking in the first provider call—therefore could prevent `run_guard` from returning, so the post-return provider assertion could never fire.

-**General rule:** A timeout usually serves two purposes: semantics and liveness. Removing wall time from semantic synchronization can silently remove the only independent hang bound. Preserve deterministic virtual time for subject semantics, but provide a separately implemented real-clock liveness watchdog and prove that watchdog fires.
-
-Remediation:
-
-- Every guard subject invocation is launched by absolute `/usr/bin/python3` in a new session. Python's internal monotonic `wait(timeout=...)` provides real-clock liveness independently of PATH; expiry kills the entire isolated process group, so neither PATH-front shims nor a blocked provider descendant can retain the capture pipe.
-- Watchdog expiry returns distinct harness rc 90 plus `FAIL HANG watchdog`, separate from subject timeout rc 124.
-- A first attempt using absolute `/usr/bin/timeout -s KILL` passed on GNU coreutils but failed in the exact Alpine CI-base image: BusyBox killed the immediate wrapper while the guard/provider descendants survived and retained the command-substitution pipe. The process-group kill is therefore required behavior, not portability polish.
-- A committed positive control hangs the branch-provider stub before the status endpoint. It must terminate through the watchdog, emit the hang-specific diagnostic, return rc 90, and prove the status provider was never reached.
-- RED before remediation: a temporary ordinary-success mutant hung before provider observation; only an external control could kill the suite (rc 137), and there was no internal hang-specific diagnostic (`red-watchdog-absent.log`).
-- The watchdog mutant/control is load-bearing: removing the internal watchdog leaves the control unable to produce its required rc 90 and diagnostic.
-
-Post-review evidence:
-
-- Host focused harness with process-group watchdog: rc 0 (`green-watchdog-process-group-host.log`).
-- Exact Alpine CI-base focused harness with process-group watchdog: rc 0 (`green-watchdog-ci-image.log`).
-- Hanging ordinary-success mutant: suite rc 1; success returned rc 90, emitted `FAIL HANG watchdog`, and loudly reported that provider/clock observation did not occur (`red-watchdog-fires.log`).
-- Removed-`-t 1` mutant: suite rc 1; pending was terminated by the watchdog instead of producing `ASSERTED_NOT_READY`, proving the explicit timeout is load-bearing (`red-timeout-argument-removed.log`).

Remaining: inspect final diff, shell/static/baseline gates, independent code/security review, remediation if any, identity-bound commit/trailer verification, mandatory queue guard plus direct terminal Woodpecker `mosaic` enumeration, push, self-posted PR/provider poster read-back, exact-head terminal-green CI, coordinator merge authorization, squash merge, main CI verification, and leave #1019 unclosed as `believed-fixed, pending jarvis validation`.

-# #1051 — per-estate mosaic-brain installer
-
-Last updated: 2026-08-05
-
-## Objective
-
-Codify estate-derived, repository-backed `~/.mosaic` support with secret exclusions, non-destructive migration, doctor diagnostics/fixes, and credential-contract terminal-class handling. Live broker grants and live read/write round-trips remain gated on MC-CRED-01.

-
-## 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()`; the 32-line permissive shim was removed. After exact-head CI proved the cross-PR source dependency was absent, the provider-fetched canonical registry implementation, DTO dependencies, and registry tests were tracked byte-for-byte on this branch so a fresh checkout validates the real seam rather than a stub. A later rebase onto merged MC-CRED should recognize those identical files as upstream.
-- [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.

-## Exact-head CI dependency remediation
-
-- Pipeline `#2222` at `a50b5a6b` ran the sole pull-request-eligible workflow (`ci`, 1/3 defined workflows) and failed `typecheck` with two `TS2307` errors before lint, format, or tests could execute.
-- History establishes that the imports are intentional: commit `2451c2f` introduced both consumers, while the contemporaneous registry-seam report explicitly called the local 32-line implementation a disposable scaffold and required MC-CRED's canonical parser. This was a deliberate cross-PR dependency, not a wrong import or forgotten shim add.
-- RED-first root typecheck reproduced the two missing-module errors. The fix tracks the provider-fetched MC-CRED registry, its two DTO dependencies, its unit test, and the result DTO dependency. Three DTO files remain byte-identical to `fbff4ffa`; author review found that the canonical parser accepted a trailing-slash origin which MB-BRAIN consumers concatenate into double-slash URLs, so the parser and test are intentionally hardened here pending propagation to MC-CRED.
-- R7 removed the tracked registry module and root typecheck returned RED with three missing-module errors (the two production consumers plus the registry unit test); restoring the same SHA-256 returned typecheck to 45/45 tasks.
-- With the suppressing typecheck failure removed, lint ran 25/25 tasks and formatting passed. Full tests actually ran: 1,607/1,614 passed; the seven failures are the four pre-registered P7 integration tests intentionally held for C1/MC-CRED integration plus the three previously disclosed ambient update-banner CLI smoke failures. No test was weakened. Build ran 25/25 tasks.
-- Author review's trailing-slash finding was reproduced RED (`https://git.example.invalid/` accepted), then fixed by requiring the configured source to equal `URL.origin`; the control reran GREEN. Security review reported risk `none` with zero findings; final code re-review remains required after remediation.
-- This is a second instance of the `#1068` suppression class: an early integrity failure prevented every downstream stage carrying behavioral evidence from running while the workflow's aggregate failure looked like a completed check. Workflow reordering remains `#1068` scope and is not changed here.

-# RM-01 — Reproducible checkout
-
-- Task/ref: RM-01 (`docs/remediation/TASKS.md`, internal mission tracking)
-- Objective: make checkout/install/typecheck hooks fail on code rather than environmental residue, for root CI and non-root seats.
-- Scope: pnpm store configuration, transactional Husky installation, dependency/generated-state preflight, checkout regression tests, developer documentation.
-- Constraints: isolated worktree; no skip-switch fixes; no writes under `/root` or `/tmp`; workers do not edit `docs/remediation/TASKS.md`; author does not review or merge.
-- Acceptance: AC1–AC8 from the orchestrator dispatch/addendum.
-- Plan:
-  1. Add RED-first tests for missing dependencies, stale/foreign `.next`, and interrupted hook installation.
-  2. Implement environment-overridable HOME-based pnpm store defaults, deterministic preflight, and transactional hook installation.
-  3. Run focused tests, install/build/baseline gates, and explicit AC negative controls.
-  4. Obtain independent review, push after queue guard, open PR, and send evidence to `mos-remediation`.
-- Budget: orchestrator estimate 6K/60K; no explicit hard token cap. Keep scope to RM-01 and avoid unrelated cleanup.
-- Risks: 97%-full shared `/tmp`; native dependency install size; root-owned fixtures may require Docker for realistic verification.
-
-## Progress / evidence
-
-- Worktree created at `/home/hermes/agent-work/rm-01` from `origin/main` `06e0d403`.
-- `/tmp` baseline: 28G used, 889M available (97%); worktree and planned store are on `/home`.
-- Root causes confirmed from source: committed `.npmrc` pins `/root`; `prepare` invokes Husky directly; web typecheck includes generated `.next` types without validating ownership/freshness.
-
-## Checkpoint evidence (c45e5e19)
-
-- AC1 IN PROGRESS: non-root `pnpm install --frozen-lockfile --store-dir "$HOME/.local/share/pnpm/store"` exited 0; `pnpm exec turbo run typecheck --force` exited 0 (45/45 uncached). Clean CI-container run not performed.
-- AC2 DONE: with `node_modules` absent, `pnpm preflight` exited 42 with `MOSAIC_PREFLIGHT_MISSING_DEPS` and `run pnpm install`; after install it exited 0.
-- AC3 DONE: appending `export const x: number = "s"` to `packages/types/src/index.ts` made `pnpm -w typecheck` exit 2 with TS2322; reverting made it exit 0.
-- AC4 IN PROGRESS: local `pnpm -w build` exited 0 and `git status --porcelain` showed no generated residue beyond the intended RM-01 source changes. Fresh-clone proof not performed.
-- AC5 DONE: non-root install exited 0; `pnpm store path` resolved `/home/hermes/.local/share/pnpm/store/v10`; no `/root` write was attempted.
-- AC6 IN PROGRESS: focused failure/rollback tests passed, but final review found a concurrent-install race. Two installers can both observe `.husky/_` absent; after one installs successfully, the losing install's catch path can quarantine the winner's active hooks and restore stale Git config (`scripts/install-hooks.mjs`, activation/catch transaction). A RED regression is committed after the checkpoint.
-- AC7 DONE: install/store/worktree were on `/home`; full `pnpm -w build` exited 0; `/tmp` usage changed by 4096 bytes during the build (23,805,173,760 → 23,805,177,856 bytes), not materially.
-- AC8 DONE for the implemented path: store resolves under `$HOME`; test/quarantine/build state resolves under the worktree; no implemented component requires a writable path outside `$HOME` or the worktree.
-
-## Continuation evidence
-
-- AC6 DONE: the committed race reproducer was observed RED (`node --test --test-name-pattern='a competing successful installer is not removed by the losing process' scripts/install-hooks.test.mjs`, exit 1/ENOENT), then passed after cleanup became ownership-safe. The losing installer never removes an active hook set or restores Git configuration it did not activate. `pnpm test:checkout` passes 21/21, exit 0, including the original race and a post-rename peer-replacement regression.
-- Generated-state remediation: replaced mtime inference with a source/build-input fingerprint, written only after a serialized successful Next build with unchanged inputs. Failed/interrupted/overlapping builds leave no trusted marker. The fingerprint uses Next's own environment loader, covers resolved `NEXT_PUBLIC_*` values, inherited TypeScript configuration, lock/workspace inputs, and rejects symlink inputs.
-- Baseline: `pnpm typecheck`, `pnpm lint`, and `pnpm format:check` each exit 0. Local `pnpm test` still exits 97 only at the pre-existing Bash `BASH_LINENO` convention guard (#973/#1003), after checkout tests and package tests pass; this is not reported as a green full-suite result.
-- Automated review remediation: resolved findings for peer-hook ownership, stale/failed build markers, build-input changes, expanded environment inputs, inherited TypeScript config, symlink inputs, and overlapping build serialization. Independent PR review remains assigned to rev-974.
-- AC1 DONE at `0f706119`: a clean clone created inside `git.mosaicstack.dev/mosaicstack/stack/ci-base:latest` ran the exact acceptance sequence `pnpm install --frozen-lockfile && pnpm -w typecheck`; exit 0 with 45/45 uncached typecheck tasks successful. An earlier bind-mounted clone attempt exited 1 because root in the container rejected the host-owned Git directory; that failed attempt is not counted as evidence.
-- AC4 DONE at `0f706119`: in that same fresh clone and CI image, `pnpm -w build` completed 25/25 tasks and the immediately following `git status --porcelain` was empty; combined assertion exit 0.
-- Push BLOCKED after the required queue guard: `git push origin fix/rm-01-reproducible-checkout` was rejected by Gitea with `User permission denied for writing` / `pre-receive hook declined`, despite `MOSAIC_GIT_IDENTITY=f10-coder` resolving username `f10-coder` from the provisioned `gitea-mosaicstack-f10-coder.token`.
-
-## Review remediation — restated AC2
-
-- Independent review correctly found that an added symlink under a successfully built `.next` tree passed preflight. The exact reviewer control, `ln -s /etc/hosts apps/web/.next/reviewer-symlink && pnpm preflight`, was observed passing before remediation.
-- The original blanket symlink wording conflicts with AC4 because canonical Next `output: 'standalone'` emits legitimate pnpm dependency symlinks. The coordinator independently verified 42 such links and approved the operative restatement: `.next` itself must not be a symlink; descendant symlinks must exactly match the successful build's certified manifest.
-- RED-first controls were observed failing together against the prior implementation (exit 1): `.next` root, added, removed, retargeted, tampered-manifest, and canonical-style certified-link cases. The build now publishes the manifest atomically before the existing source certification commit marker; that marker binds the manifest SHA-256. Missing/partial/modified manifests remain untrusted.
-- GREEN evidence: the six-case symlink control passes; the exact reviewer-added link exits 43; removing it restores preflight exit 0. The added RED-first build-publication control also proves a symlinked `.next` cannot redirect certification writes outside the checkout. `pnpm test:checkout` passes 23 top-level tests / 29 including subtests. Canonical `pnpm --filter @mosaicstack/web build` and the following `pnpm preflight` both exit 0.
-- Threat-model ruling: the manifest detects accidental, independent, stale, and foreign-residue mutation—the class exposed by the five-month-stale `.next` that produced 19 phantom TS2307 errors. It does not defend against a same-UID actor able to rewrite both manifest and marker consistently (CWE-345); no local worktree construction can without an external trust anchor. RM-59 tracks the residual: executor/spine-side attestation outside worktree authority, dependent on RM-12, RM-21, and RM-25.
-- AC8 concrete proof at `df7530ae`: a clean clone ran in `ci-base:latest` with Docker `--read-only`; its only writable mounts were `/workspace` (the worktree) and `/home/ci` (`HOME`, with `NPM_CONFIG_STORE_DIR=/home/ci/store`). `pnpm install --frozen-lockfile && pnpm -w typecheck` exited 0 with 45/45 uncached tasks. This proves the implemented checkout path requires no writable location outside `$HOME` and the worktree. An initial fixture attempt failed only because Git required `/workspace` safe-directory setup; it is not counted as evidence.
-
-## Handoff
-
-1. Keep the newly committed RED tests red until implementing: (a) source-fingerprint marker support for valid incremental `.next` output, and (b) ownership-safe concurrent hook activation.
-2. The latest automated review rejected oldest-generated-file mtime as a false positive for valid incremental Next output. Use a source-content fingerprint marker written only after successful `next build`; do not continue tuning mtimes.
-3. For Husky, generation in an isolated temporary Git repo avoids mutating real `core.hooksPath` during staging. Preserve that design. Fix the losing concurrent process so it never removes a peer's completed hook set or restores stale config.
-4. Codex review runs in a read-only sandbox, so its attempts to run the fixture-writing Node tests report opaque test-file failures. The same tests run normally in the worktree.
-5. Full `pnpm test` is not green on this host: it exits 97 at the pre-existing Bash `BASH_LINENO` convention guard (#1003), after the changed checkout tests and package tests pass. Do not weaken that gate.

-# RM-03 — CI Queue Guard Repair
-
-- **Task:** RM-03
-- **Issue:** #1019
-- **Branch:** `fix/rm-03-queue-guard`
-- **Owner:** coder-mos1
-- **Reviewer:** rev-974 (independent; author != reviewer)
-- **Started:** 2026-08-01
-
-## Objective
-
-Repair the mandatory CI queue guard so it reads provider payloads, blocks asserted non-green CI, distinguishes provider unavailability from a real non-green result, and inspects the branch actually being pushed or merged.
-
-## Constraints
-
-- Worktree only: `/home/hermes/agent-work/rm-03`; never mutate `/src/mosaic-stack`.
-- JSON payload travels through stdin; never argv. Large payload must remain below no ARG_MAX dependency.
-- TDD is mandatory. Every behavior case must be observed red before implementation.
-- No bypass flags or hook suppression.
-- Do not cite the existing guard's green as evidence; D-23 establishes it is zero-information.
-- Gate-ready is a frozen exact head. Any push after a merge-gate verdict voids that verdict.
-- No merge: coordinator holds the merge hand pending Jason.
-
-## Design
-
-1. Feed JSON to `python3 -c` on stdin, including pending-context rendering.
-2. Classify valid green as `READY`; pending/failure/no-status/malformed/mixed as `ASSERTED_NOT_READY`; provider/credential/transport inability as `CANNOT_ASSERT`.
-3. `ASSERTED_NOT_READY` exits nonzero. `CANNOT_ASSERT` emits a loud diagnostic and appends a local JSONL audit record. Push degrades to exit 0; merge holds with distinct retryable exit 75 until provider recovery, then self-clears without manual reset. Inability to write the audit exits nonzero.
-4. Derive the current branch when `-B` is omitted. The merge wrapper passes the exact PR head branch, repository, and full commit SHA—not its `main` base—so fork PRs cannot resolve against an adjacent base-repository branch.

-- `bash packages/mosaic/framework/tools/git/test-ci-queue-wait-tristate.sh` → rc 1 with 15 failed assertions.
-- Success payload was reported `state=unknown`.
-- Pending, failure, no-status, and malformed payloads each exited 0 and omitted `ASSERTED_NOT_READY`.
-- The 160 KiB payload produced rc 141 because Python never consumed the pipe; it did not classify success.
-- Provider-unreachable exited 7 with no `CANNOT_ASSERT` audit record.
-- Implicit push queried `/branches/main`, not `/branches/fix/rm-03-fixture`.
-- Audit-unavailable emitted no audit diagnostic.
-- A credential-resolution hard-block mutant was then run before trusting that added case: `credential-unresolvable` returned rc 1 and omitted `CANNOT_ASSERT`; the matrix returned rc 1 with two named assertion failures.
-- Review-blocker controls were observed red: structurally invalid `statuses` string and null-entry payloads each exited 0 as `terminal-success`; unsupported-platform discovery exited 1 without diagnostic or audit (seven named assertion failures total).
-- After the push/merge asymmetry ruling, merge-side provider unavailability was observed red at rc 0; its registered case required distinct retryable rc 75.
-- Aggregate `state=success` with zero contexts was observed red: it exited 0 as `terminal-success`; the registered case requires `no-status`/nonzero.
-- Fork/exact-head controls were observed red: `pr-merge.sh` omitted the fork repository and full SHA, and an ignored-arguments mutant re-resolved through `/branches/` instead of the exact fork commit (two named failures).
-- GitHub check-run-only success/pending/failure were each misclassified as `no-status`; the RED run had five named failures and proved the Checks API was never queried.
-- The first merge-pin control was unrunnable because one `local` declaration referenced a variable before assignment under `set -u`; this was disclosed and corrected rather than counted. The runnable RED then showed Gitea payload `{"Do":"squash"}` lacked `head_commit_id`; a separate GitHub run showed `gh pr merge 123 --squash` lacked `--match-head-commit`.
-- A stale-verdict mutant removed the `--expect-head` comparison and was observed red because a moved head reached the provider merge call.
-- `bash packages/mosaic/framework/tools/git/test-pr-merge-queue-branch.sh` initially returned rc 1; captured call was `--purpose merge -B main -t 900 -i 15`.

-## Progress
-
-- [x] Mission, remediation charter, task evidence, board, issue #1019, and superseded PR #1023 read.
-- [x] Isolated worktree created and identity configured coherently.
-- [x] Mutant tests authored and observed red.
-- [x] Implementation green.
-- [x] Baseline and focused situational gates green; full package suite has an unrelated framework-shell environment abort recorded below.
-- [ ] Independent review clean (rev-974 requested changes at `44ffa99a`; bypass remediation committed and awaiting re-review).
-- [ ] PR CI terminal-green at exact head by full step scan.
-- [ ] Merge-gate verdict issued against frozen head.
-
-## Scope disposition
-
-- The five framework guides are consequential documentation: they define the purpose-aware tri-state contract, including audited push degradation and merge HOLD.
-- The agent templates are consequential because they ship the same queue-guard instructions into newly seeded agent contracts; leaving them binary/stale would contradict the repaired tool.
-- `pr-merge.sh` is consequential: it must inspect the PR's exact head branch/repository/SHA and enforce the exact-head merge pin.
-- `pr-metadata.sh` is consequential only as the normalized source of that head branch/repository/SHA. Its diff is limited to exposing those fields on GitHub and Gitea.
-- `test-pr-merge-gitea-empty-uid.sh` changes because exact-head Gitea merges now always use the API path (the only path that can send `head_commit_id`), superseding the prior tea-empty-identity fallback behavior.
-
-## Review remediation
-
-- rev-974 independently proved that the documented `--skip-queue-guard` merge option bypassed an exit-99 guard stub, reached the provider merge payload, printed success, and exited 0 at head `44ffa99a`.
-- RED-first reproduction was added to `test-pr-merge-head-pin.sh` before the production fix: `FAIL merge-bypass: --skip-queue-guard reached the provider merge path`, suite rc 1. The test-only commit is `241113e6`.
-- Production remediation `37aae650` removes the option from parsing, usage, help, and examples. Every merge-capable path now invokes the queue guard; `--dry-run` alone omits it and has a regression proving that it exits before provider dispatch and creates no merge payload.
-- Existing Gitea merge tests now exercise a successful guard response rather than bypassing the guard.
-
-## Risks / boundaries
-
-- The local JSONL audit is durable operational evidence but not tamper-resistant against the same UID. RM-03 does not claim otherwise.
-- Push-side audited exit 0 is an explicit owner ruling (Option B), accepted to avoid bricking recovery work; merge-side CANNOT_ASSERT remains retryable exit 75/HOLD. The automated security reviewer continues to flag the deliberate push availability tradeoff.
-- Source/deployed-copy equality is owned by RM-02/D-22; this branch changes repository source and its tests only.
-
-## Test evidence
-
-Fresh after rescue checkpoint `b7175012`:
-
-- Focused situational matrix: tri-state, GitHub checks pagination, branch-absent, merge head branch/repository/SHA, exact-head pin, and Gitea exact-head API regressions all passed.
-- `bash -n` on the three production shell scripts passed.
-- `shellcheck -x -P packages/mosaic/framework/tools/git ...` on all changed shell scripts passed.
-- `pnpm typecheck` passed (45/45 Turbo tasks).
-- `pnpm lint` passed (25/25 Turbo tasks).
-- `pnpm format:check` passed.
-- `pnpm --filter @mosaicstack/mosaic test`: Vitest passed 1508/1508 on the confirmation run; framework-shell then aborted at the pre-existing wake coordinate assertion with exit 97: `BASH_LINENO ... probe reported [3 5], expected [3 4] ... (#973)`. This is outside the RM-03 diff and is disclosed rather than substituted or called green.
-- The prior package-suite attempt had one transient, out-of-diff `install-ordering-guard.spec.ts` failure (1/1508); its isolated rerun passed 19/19 and the confirmation full Vitest run passed 1508/1508.
-- After bypass remediation: all six focused RM-03 queue/merge regressions passed, including bypass refusal and dry-run non-dispatch; shell syntax and source-aware ShellCheck passed; `pnpm typecheck`, `pnpm lint`, and `pnpm format:check` passed.
-- Fresh `test:framework-shell` reached and passed every RM-03 test, then again aborted at the unrelated wake coordinate assertion with exit 97; it remains explicitly non-green rather than substituted.
-- An ad hoc raw Prettier invocation over `.template` and `.sh` files was unrunnable because no parser is registered for those extensions; it was not used as a substitute for canonical `pnpm format:check`.

-The verifier reports the expected and observed commits, total step count, state counts, anomalies, and any applied exemption.

-
-- pipeline and workflow state are `success`;
-- exactly one non-success child exists;
-- its name is `ci-postgres` and type is `service`;
-- its state is `failure`, exit code is the JSON integer `0` (not boolean, float, string, or null); and
-- its error exactly matches `pods "wp-svc-<ULID>-ci-postgres" not found`.

-Every near miss remains blocking, including non-zero service exits, startup failures, post-readiness crashes, connection errors, image-pull errors, skipped steps, another failed child, malformed pod names, duplicate matches, or a non-success pipeline/workflow.
-
-**Boundary in both directions:** this exemption recognizes the observed Woodpecker Kubernetes reconciliation miss after an otherwise-successful run. It does not prove that every future PostgreSQL or Kubernetes failure is distinguishable. It does prove, through provider controls, that a deterministic startup failure (`exit_code=1`) and an armed post-readiness postmaster crash (`exit_code=137`, dependent probe `Connection refused`) do not match and remain red.

-**Tracking and retirement:** [mosaicstack/stack#1000](https://git.mosaicstack.dev/mosaicstack/stack/issues/1000) owns the provider-seam fix. This exemption MUST be removed when #1000 is fixed. It is not authority to retry or re-trigger a pipeline, and no per-PR re-roll is part of the contract.
