# mos-remediation — LIVE BOARD (keep < 8 KB)

**Phase:** EXECUTING — RM-03 at owner-merge; RM-61 **MERGED**; **RM-02 keystone is the front**.
**Updated:** 2026-08-01 — seam crossed; successor seat resumed, attested from the files, and is driving.
⚠ That was a **MANUAL pane respawn** (prior seat ~803k tokens): it validates the checkpoint+rehydration
**design**, NOT a lifecycle **mechanism** — P-LIFECYCLE rotation does not exist yet (**D-41 / RM-62**).

## Head

- 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 48 findings
   (D-1…D-6 in `BOARD-LEDGER.md`, D-7…D-47 + 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.

## Delivery gates — REFERENCE, do not restate

Canonical: `~/.config/mosaic/fleet/roles.local/merge-gate.md` (verdict authority) +
`~/.config/mosaic/fleet/roles/validator.md`. Order and the freeze/zero-information rules: `MISSION.md`
and `KICKSTART.md`. **Read them there** (why: **D-26**, in `BOARD-LEDGER.md`).

## Fleet seats

Roster rolled verbatim to [`BOARD-LEDGER.md`](./BOARD-LEDGER.md); live truth is `mosaic fleet ps`.

## Gate status

- Freeze: LIFTED for this workstream only.
- 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 + 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.

## Decisions log — full record in [`TASKS.md`](./TASKS.md)

All 48 findings (D-1…D-6 in `BOARD-LEDGER.md`, D-7…D-47 + D-38c in `TASKS.md`) and every ruling with
its rationale live there. **Not duplicated here.** The history of _why_ this board must not restate —
six stale copies across two seams — is rolled verbatim into [`BOARD-LEDGER.md`](./BOARD-LEDGER.md).
