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

**Phase:** EXECUTING — P0 open. RM-01 MERGED; RM-02 (keystone gate registry) is next.
**Updated:** 2026-07-31 (mos-remediation orchestrator; seat active on `mosaic-fleet`).

## 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.

## Fleet seats

- mos-remediation — project orchestrator (Claude, /src/mosaic-stack, socket `mosaic-fleet`) — ACTIVE
- planner-opus — adversarial planner (robustness), Opus 5, socket `default` — DELIVERED, idle
- planner-sol — adversarial planner (pragmatic), gpt-5.6-sol, socket `default` — DELIVERED, idle
- rev-974 — mosaicstack reviewer identity (id 16, write:repository) — idle, on call
- Mos (mos-claude) — lead coordinator, socket `default` — relay path to Jason

## Gate status

- Delivery gates active: author≠reviewer, diff-blind pre-registered checks, CI-green, merged-PR completion.
- Freeze: LIFTED for this workstream only.
- Git identity: `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`.
- 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.

## Sequencing (from MISSION.md)

1. Spine + choke-point service (MACP wiring @ mosaic_orchestrator.py::run_single_task) + PG/Redis
   ⚠ **CONTESTED — see DECISION-1.** Both planners independently reject this wire-in point: that
   controller is `"enabled": false` and references a dispatcher that does not exist here. Charter text
   left UNCHANGED pending Mos/Jason ruling; do not treat it as settled.
2. Rotation daemon (finish Mission Control Plane, reuse packages/coord)
3. Comms service (envelope→service→PG/Redis→adapters)
4. Hygiene + conformance harness
   Cross-cutting retirements: flat-file tracking, 3 MACP islands, silent MOSAIC BYPASS.

### **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.

## Decisions log

- 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).
