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

Phase: EXECUTING — RM-02 (keystone) at review; RM-03 design-first; 27 findings banked. 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.

Delivery gates — DOCTRINE CHANGE 2026-08-01

The gate definition was incomplete from mission setup: the merge-gate verdict step was missing. Root cause (D-26): the gates were restated from memory into MISSION.md/KICKSTART.md instead of referenced, and the omission propagated into every worker brief issued since. It then recurred inside the correction — which dropped five details including a security precondition and cited a file that does not exist.

Fix is render-not-restate, mechanically. MISSION.md and KICKSTART.md now reference ~/.config/mosaic/fleet/roles.local/merge-gate.md and ~/.config/mosaic/fleet/roles/validator.md and state only the gate order:

independent review (author ≠ reviewer) → remediation → CI terminal-green at the exact head, full step scan → merge-gate verdict GO/NO-GO/HOLD (commit-bound; VOID on head move; posted durably with enumerated evidence under its own minted identity) → coordinator head-pinned merge

• After a GO, pushes freeze — a doc tweak voids the verdict. Gate-ready is a freeze point.
• The coordinator assigns the gate seat; the orchestrator owns getting a PR gate-ready.
• Queue guard is ZERO-INFORMATION until RM-03 lands (D-23) — record it as queue-guard: ZERO-INFORMATION (inert, D-23, owner RM-03). A mandated field must not become a manufactured one.
• Gate seat identity: gitea-mosaicstack-merge-gate minted least-privilege, verified push=False — it structurally cannot merge.

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.

Dogfood evidence — live failure classes, not hypotheticals

Newest first. Oldest entries roll to BOARD-LEDGER.md via board-roll.sh when this file exceeds its 8 KB cap. Keystone detail is duplicated in TASKS.md §1a, so rolling loses nothing.

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.

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).
