MC-4357

ADDITIONAL FALLOUT from the same 6-worker auto-review cascade — branch-state incident: The LIVE mission-control serving repo (~/workspace/mission-control, gunicorn WorkingDirectory) is checked out on branch slot2/mc-MC-4327, NOT master. A worker committed in the MAIN serving repo instead of a pool worktree slot (violates worktree-pool rule 10). - HEAD=bd796c8, 4 commits ahead of origin/master, NOT pushed/merged: bd796c8 MC-4350, b997f5f MC-4352, 1ad044b MC-4351, b47a718 MC-4353 (on 860f326 MC-4327) - ~824 lines uncommitted across test files (test_mc4207/4321/4322, test_workflow_idempotency) — investigate before discarding. - MC-4349/4351/4352/4353 marked DONE but fixes are NOT on master (consistent with the strand symptom: status advanced without the landing being verifiable on master). Deliberate reconciliation needed (do NOT blind-checkout master/restart gunicorn — blast radius on live port 3001): 1. Stash+inspect the uncommitted test changes; attribute to a worker/ticket. 2. Run the 4 fix regression tests. 3. Merge slot2/mc-MC-4327 -> master cleanly, push origin/master. 4. Return main repo to master; restart luci-dashboard in a quiet window. 5. Add a git-layer guard so workers cannot commit/checkout in the main serving repo.

Luci picking up this ticket (background worker).

Ticket picked up by Luci via MC dispatcher. MC-4357: Harvest DB-write race strands completed tickets in needs_input (signal-miss recurrence) Work this ticket in the live tmux runtime. Use DONE:, REVIEW:, or QUESTION: when you need MC to reflect the next state.

Triage (orchestrator): the worker QUESTION on this ticket is corrupted noise ("when you need MC to relect the next state" + mangled turn marker) — that IS the harvest/runtime-collision symptom this ticket tracks, not a real question. Not actioning it as a question. Parking to `waiting` (out of the todo pickup queue) to stop the worker-question nag loop and prevent blind auto-dispatch into the unresolved race (circuit-breaker: do not re-feed work into the broken machine). This is keystone systemic work — it needs deliberate handling in a controlled session with serialized dispatch, not an auto-worker that will hit the same collision. See also the stranded-branch fallout comment above (slot2/mc-MC-4327).

Update to branch-reconciliation state (MC-4338 just closed): - Dirty-tree (was ~824 lines uncommitted) → RESOLVED. Worker committed coherent WIP as acb068e, working tree now CLEAN. Reconciliation step #1 done. - slot2/mc-MC-4327 now pushed to origin and is 6 commits ahead of origin/master: bd796c8 (4350), b997f5f (4352), 1ad044b (4351), b47a718 (4353), c0c631b (4345), acb068e (4338). - Remaining: merge slot2/mc-MC-4327 -> master cleanly, push, return live repo to master, restart luci-dashboard in a quiet window, add git-layer guard against committing in the main serving repo.

RECONCILIATION PROGRESS — 4 verified fixes landed on master: - origin/master fast-forwarded 860f326 -> bd796c8 (non-destructive ref push). MC-4350/4351/4352/4353 now on master, all closed. No working-tree switch, no service restart. Remaining on slot2/mc-MC-4327 (NOT on master, by design): - c0c631b MC-4345 (AionUI Home rebuild) — UI work, needs Tessa UI gate before it can land/go live. - acb068e MC-4338 (campaign_owner API + mobile-gate WIP). Open items for the deliberate session: 1. Tessa-validate MC-4345; if APPROVED, land + decide live cutover. 2. Return the main mission-control checkout from slot2/mc-MC-4327 to master (working tree still on slot branch; gunicorn unaffected since no restart since 23:18). 3. Add git-layer guard so workers cannot commit/checkout in the main serving repo. 4. Fix shadow-review so it can fetch slot-branch diffs (currently marks them uncertain/fail -> bounce loops).

Integrity flag: MC-4345 (AionUI Home rebuild) is now marked DONE — but it did NOT pass a Tessa UI gate and its code (c0c631b) is NOT on master (deliberately excluded from the 4-fix ff-push; lives only on slot2/mc-MC-4327). Do NOT trust this `done`. During reconciliation: either run the Tessa gate + land it properly, or reopen. Same auto-close-without-gate pattern this ticket tracks.

WAITING REASON (board-sweep flagged missing): parked pending the deliberate slot2/mc-MC-4327 -> master branch reconciliation + Tessa gate of MC-4345. Not auto-dispatchable until the harvest-race is understood (circuit-breaker). CRITICAL regression resolved this session (was breaking ticket-pickup every dispatch-error): scheduler's new status='warning' (exit-75) violated the task_runs CHECK constraint IN(running/completed/failed/timeout) on live mc.db -> 'CHECK constraint failed'. Fixed: - migration 019_warning_task_run_status.py rebuilds task_runs to allow 'warning'. APPLIED to live mc.db (integrity ok, 66k rows preserved, indexes intact, warning-insert verified). Idempotent. - pg_schema.py CHECK widened. Both landed on origin/master via cherry-pick 84335c3 (clean, no feature WIP). - scheduler regression test hardened to use the real CHECK (root cause it slipped through: test table had no constraint). Branch-state note for reconciliation: the slot2 checkout has a LOCAL-ONLY commit ba2a287 (same migration, unpushed) that duplicates master's 84335c3 — harmless (identical content, will auto-merge), but can be dropped when reconciling. Pre-existing unrelated data debt also surfaced: 4 orphaned ticket_comments rows (FK to deleted tickets) — not caused here, worth a separate low-pri cleanup.

*** CRITICAL CONSTRAINT added to reconciliation — schema version *** MC-4348 bumped EXPECTED_SCHEMA_VERSION 19->20 and added migration 020 (chat_threads.runtime_session_key honesty gap). I have APPLIED migration 020 to the live mc.db: user_version is now 20 (integrity ok). The live checkout (slot2/mc-MC-4327, models.py EXPECTED=20) matches the db — restart-safe NOW. BUT origin/master is still at EXPECTED_SCHEMA_VERSION=19, and 36b1d4b (the bump + migration 020 + tests) is NOT on master. verify_schema_version raises on ANY mismatch (strict). Therefore: >> DO NOT return the main mission-control checkout to master until 36b1d4b lands on master. Restarting MC on master code (expects 19) against the now-v20 live db will RAISE and MC will not start. << Landing 36b1d4b on master via piecemeal cherry-pick FAILS: it conflicts on tests/test_mc4207_phase3_evidence.py (also modified by the excluded MC-4338/acb068e). Confirms the reconciliation must be HOLISTIC — gate MC-4345 (Tessa), then merge slot2/mc-MC-4327 -> master as a unit (bringing 4345/4338/4348 together), not commit-by-commit. Sequence the merge + return-to-master + (optional) restart as one deliberate operation.

parked_backlog: parked pending the deliberate slot2/mc-MC-4327 -> master reconciliation (gate MC-4345 via Tessa, holistic merge carrying 4345/4338/4348 + schema-v20 bump, return repo to master only after 36b1d4b lands) and the harvest DB-write race fix itself. Not auto-dispatchable — see prior comments for the full plan + constraints.

SLOT2 BATCH MANIFEST (consolidated — all work committed on slot2/mc-MC-4327, awaiting the holistic merge; do NOT gate/close individually, they land together): - bd796c8 MC-4350 harvest lock + flush (verified, 3/3 tests) — done-pending-merge - b997f5f MC-4352 / 1ad044b MC-4351 / b47a718 MC-4353 (verified) — done - c0c631b MC-4345 AionUI Home rebuild — needs Tessa UI gate before live - acb068e MC-4338 campaign_owner API + mobile-gate WIP — done - 36b1d4b MC-4348 schema v20 migration (APPLIED to live db; master must reach v20 before any return-to-master) - 6344edd MC-4326 AionUI Home launcher (scope B) — *** SCOPE FLAG: ticket title is "Make MC mobile visual review gate blocking" but the commit is Home-launcher work. Clarify whether MC-4326 was repurposed to Home-launcher, or the mobile-visual-gate work is still undone, before closing. *** - mc_orchestrator_flags.py MC-4342 review_retry/tessa_gate flags (both DEFAULT OFF = merge-safe) — code done; activation needs (a) master merge, (b) Elmar OK to restart the live scheduler/service. Reconciliation sequence unchanged: Tessa-gate MC-4345 -> merge slot2 -> master holistically (carries all above) -> return main repo to master (only after this, since live db is v20 and master must match) -> Elmar-approved restart to activate MC-4342 flags. MC-4326 scope must be clarified in the merge.

Manifest addendum — AionUI Home CLUSTER: MC-4324/4326/4345/4338 are ONE overlapping feature (chat/launcher-first Home, self-serve campaign creation, mobile cockpit removal, campaign_owner API) spread across slot2 commits 6344edd + acb068e + c0c631b under mixed ticket tags. MC-4324 has NO own commit (work blended into 6344edd/acb068e) — do not expect a per-ticket diff. Verify the COMBINED Home deliverable with ONE Tessa UI gate (desktop+mobile) against all four tickets' requirements, then close the cluster together at the holistic merge. Stop per-ticket gating of this cluster.

Home cluster addendum: + MC-4370 (commit 8f86e41 'AionUI-quality Home polish — quiet model chip, elevated composer' = current slot2 tip, pushed). Full Home cluster now: MC-4322(base/master) + MC-4327(base/master) + slot2: MC-4345/4338/4326/4324/4370. Combined Tessa gate covers all slot2 Home tickets; 8f86e41 is the slot2 HEAD to merge.

Manifest: + MC-4371 fix 2480c00 (shadow-review cross-repo resolve + abstain + never-reopen-gated; 49 tests pass) — slot2-bound, touches models.py/ticket_runtime.py/test_mc4207 so it merges WITH the Home cluster, NOT cherry-pickable alone. PRIORITY-1 in the holistic merge: it is the bounce-storm killer. Slot2 batch is growing into a full feature+fix bundle; the holistic merge is now the single highest-leverage action to land everything + stop the churn.

Manifest: + MC-4378 (implements MC-4375 central role-contract recommendation: subprocess-path architect-brief injection + ROLE_INTROS dedup) — slot2-bound, in_progress. GATE: adopting this architecture change is Elmar's call (MC-4375 advisor recommendation, doc on master fc5164d). At merge time, include MC-4378 only if Elmar adopts the central-contract direction.

*** ROOT CAUSE PINPOINTED (was vague "harvest race", now precise + workspace-independent) *** The corrupted-question / bounce storm is NOT a DB write race. It is harvest SIGNAL MIS-EXTRACTION from the raw tmux pane: - mc_pickup harvest captures the raw tmux pane (capture-pane, ~mc_pickup.py:3220) which contains the Claude TUI rendering: progress spinners + the PROMPT-INSTRUCTION echo. - mc_pickup.py:4186 sends workers the instruction: "Use DONE:, REVIEW:, or QUESTION: when you need MC to reflect the next state." The harvest then RE-READS that instruction text off the pane and extracts it as a worker QUESTION -> "QUESTION: when you need MC to reflect the next state" parks the ticket needs_input. That exact string in every corrupted question = the prompt echo, not a worker. - Mangled spinner chars (e.g. MC-4377 "kiinWng9Wogor•rkkiinngg") confirm raw-TUI-pane capture, not structured output. This is WORKSPACE-SIDE (mc_pickup.py), INDEPENDENT of the slot2/mission-control tangle -> fixable on master NOW, no merge dependency. FIX DIRECTION (needs dev-loop, critical infra — careful + tested): - Parse worker signals from the structured stream-json / a dedicated signal channel (state/mc-signals/*.json already exists via _read_mcp_signal), NOT raw capture-pane scraping. - If pane scraping must stay as fallback, exclude the known prompt-instruction text + anchor signal match to the worker's response region (start-of-line, after the prompt), and strip TUI control/spinner chars. - Regression: feed a pane containing the prompt instruction + spinner noise; assert NO false QUESTION/DONE extracted. This is the keystone that stops MC-4323/4374/4376/4377/etc. churn. Priority raised to CRITICAL. All the corrupted-question tickets are symptoms — stop per-ticket triage; fix this.

Manifest: + MC-4376 (b7e4fca 'surface explicit pending CTA/reason on board cards + ticket detail' — app.py render-time derivation, slot2). UX improvement that complements the waiting-reason/pending hygiene. Slot2-bound, touches app.py (not independently cherry-pickable). In_review, lands with the holistic merge.

Manifest: + MC-4378 mission-control part b92c792 (canonical role intros shared source, slot2). Workspace part b90396fa already LIVE on master + verified safe. + reinforces commit-guard need: a worker committed mc_pickup.py directly to workspace master (rule-10 bypass), like the mission-control slot2 case.

Manifest: + MC-4377 (2fca3c9 controller-owned restart/deploy routing in semantic_router + wiring; 14/14 tests pass; eb4de42 test stub). Slot2-bound. NOTE: full-suite pytest collection broken by tests/test_console_panel.py (ModuleNotFoundError shared_console.blueprint) — a slot2 commit added an unpackaged shared_console ref; fix during the merge QA pass before landing.

Merge-QA list (add before/at the holistic merge): (1) MC-4376 b7e4fca lacks regression tests for the pending-CTA/reason derivation — add them; (2) tests/test_console_panel.py shared_console.blueprint packaging break — fix so full-suite pytest collects. Both flagged by shadow-review/collection during slot2 gating.

Workflow action `review_ready` applied. Work ready for review.

HARVEST FIX STATUS — preserved, NOT yet cleanly committed (worker emitted DONE on UNCOMMITTED work that was then stashed): - The MC-4357 durable-signal-claim fix (ticket_runtime.py: MCP_SIGNAL_CLAIM_TTL_SECONDS, _break_stale_mcp_signal_claim, _release_mcp_signal_claim, harvest_once reads-then-claims + no pane-fallback-when-claimed) is SAFE in `git stash@{0}` on the slot2/mc-MC-4327 mission-control checkout ("MC-3804/4357 signal-harvest WIP"). Verified: compiles, 73-74 ticket_runtime tests pass, no regression. - It is NOT committed. I could not commit it cleanly NOW because a CONCURRENT MC-4383 worker is live-editing the SAME main mission-control checkout (saw tests/test_mc4383_artifact_gate.py appear + mc_shadow_review.py/models.py churn). Resetting/checkout would destroy MC-4383's in-progress work. So I stopped — did NOT touch the working tree. ACTION for the deliberate reconciliation (quiet window, NO active workers): 1. Ensure no worker is editing the main mission-control checkout. 2. git stash apply stash@{0}; isolate ticket_runtime.py; commit MC-4357 cleanly to slot2; drop the stash. 3. Add the missing regression test (durable-claim + lock-retry; pane-instruction-echo NOT misread). 4. CAVEAT: this fix covers the write-race + claim-guard; the pane-scrape FALLBACK (MCP-less / no-signal-file) can still misread the prompt instruction as a QUESTION — that residual corrupted-question root needs separate handling. ROOT PROBLEM reinforced: multiple workers are committing/editing directly in the live mission-control checkout (rule-10 bypass) — MC-4357/4378/4383 all touched it concurrently. The commit-guard (MC-4371) is now urgent: workers MUST use pool slots, never the main serving checkout.

Parked behind MC-4371: the harvest fix is preserved in stash@{0}, but should not be reapplied/committed while the main mission-control checkout is dirty and unguarded. Resume after MC-4371 proves workers use pool slots and the main checkout is safe to reconcile.

Controller release: Elmar flagged MC-4323 as no-substance retry spam and likely board-wide. Live audit confirms no ticket tmux workers are active; several pending items are stale/slot2-bound, and MC-4323 was pure runtime-send/signal-harvest churn. This ticket is now the canonical critical repair: land the harvest signal-extraction/runtime-send fix, include slot2 merge QA noted above, and stop false QUESTION/409 retry storms. Runtime profile set to codex; pickup should start a fresh worker.

Controller repair after pickup 409 row-drift: mc-MC-4357 tmux exists and Codex is actively working; normalized ticket back to in_progress/running and cleared stale auto_requeued failure so pickup will not duplicate-dispatch.

Ticket picked up by Luci via MC dispatcher. MC-4357: Harvest DB-write race strands completed tickets in needs_input (signal-miss recurrence) Work this ticket in the live tmux runtime. Use DONE:, REVIEW:, or QUESTION: when you need MC to reflect the next state.

REOPENING — false DONE. This was marked done, but the harvest fix is NOT landed: ticket_runtime.py on slot2 has ZERO of the durable-claim code (MCP_SIGNAL_CLAIM_TTL_SECONDS count=0); the only copy is git stash@{0} on the slot2 mission-control checkout. The harvest corrupted-question bug is therefore STILL LIVE (this ticket's whole point). Closing it as done is wrong and risks losing the stashed keystone work. Setting back to waiting + critical. Real completion = commit the stash@{0} fix to slot2 cleanly (quiet window, no active workers), add the regression test, address the pane-scrape-fallback residual, then land via the holistic merge. Until then this stays OPEN.

Manifest: + MC-4397 (88f46b1 operator-noise root-cause fixes: STALE_HOURS 2->4, graphify-out known-generated, failure dedup; 8/8 operator tests). Slot2-bound. Directly reduces the repo_dirty/stale-lane false-positive churn — good complement to land in the merge.

RESOLVED — done is now LEGIT (I reopened earlier when the fix was only in stash; a proper fix has since landed on master). The holistic merge happened (origin/master 6e0e2dd). MC-4357 write-race fix is on master as 3d12462 ("harden harvest signal writes"): rename MC-<id>.json -> .claimed for recoverable claims, re-apply on a later pass if the DB write was lost, + 104 lines of new regression tests (test_harvest_once_recovers_claimed_mcp_signal_after_lost_write). This is a cleaner, TESTED implementation that SUPERSEDES my stash@{0} version (which had no test) — stash now redundant (left in place, harmless; may hold unrelated grab-bag bits). Confirmed live-evidence the churn subsided: recent worker reviews (MC-4333/4339/4344/4397/4398) came through CLEAN, not corrupted. Combined with the commit-guard (MC-4371 f72fdd5 — workers now barred from the main serving checkout) the harvest/dispatch storm is resolved. RESIDUAL to watch (not reopening): the pane-scrape FALLBACK for MCP-less / no-signal-file runtimes could still misread the prompt-instruction echo. If corrupted "QUESTION: when you need MC to reflect" recurs, that fallback path needs the same hardening. Currently quiet.

Luci Operator: promoted this assigned `inbox` ticket to `todo` so pickup can run it.

Controller incident evidence from MC-4381: the cross-repo shadow-review/done_sha fix is not optional polish. A worker correctly landed workspace commit 64926ae3, but the active review path inspected mission-control sha eb4de42 and appended a false FAIL after close. Ensure the MC-4371 fix is included/activated in the current live wiring/merge path before claiming the controller gate is healthy.

Controller normalization after full pending audit: Canonical merge/harvest blocker: signal-harvest DB-write race + slot2-to-master reconciliation. Blocks the UI/control bundle and several parked tickets.

Controller release: MC-4371 is now landed/live (f72fdd5) and its unsafe main-checkout dispatch guard is active. I preserved the previous dirty live checkout WIP before clearing it for the landing at /home/lucienne/workspace/ticket-attachments/MC-4371/live-dirty-before-mc4371-land-20260528T164001+0200 and stash `stash@{0}`; if this harvest-race ticket needs those ticket_runtime/model changes, reconcile from that artifact rather than assuming they were lost. Released from blocked_by:MC-4371 to todo for pickup. Human input required: no.

Controller dispatch verification: after MC-4371 landing/restart, pickup claimed MC-4357 and started tmux mc-MC-4357. Ticket row is in_progress; runtime session is running; live tmux pane cwd is /home/lucienne/workspace/mission-control/.claude/worktrees/pool-0, so the worker is not editing the main checkout. Cleared stale prior done_sha while the active worker runs. Human input required: no.

Controller shepherd: verified MC-4357 worker is live in tmux mc-MC-4357 with pane cwd /home/lucienne/workspace/mission-control/.claude/worktrees/pool-0; set next controller check-in to 2026-05-28T17:13:10+02:00. No Elmar input required.

Controller shepherd row-drift repair: live tmux mc-MC-4357 pane PID is 3628138 in /home/lucienne/workspace/mission-control/.claude/worktrees/pool-0; synchronized ticket.worker_pid and runtime_sessions.pid so ticket row, runtime row, and tmux agree. MC health is 200/healthy after the worker's graceful reload probe.

Controller gate rejected the current DONE signal for MC-4357: the fix is live and health is green, but /home/lucienne/workspace/mission-control still has uncommitted source changes (app.py, ticket_runtime.py, tests, docs), so the deliverable is not landed/pushed yet. I quarantined the stale DONE signal and returned the active runtime to finish the dev-loop: verify, commit, push, report DONE with sha. Human input required: no. Quarantined signal: /home/lucienne/workspace/state/mc-signals/MC-4357.json.controller-held-20260528T170305+0200.

Controller gate passed: verified commit 3d12462fe2f40e0aab42760c1bd4c23b90afcc64 is pushed to origin/slot2/mc-MC-4327, MC-4357 narrow regressions pass (3/3), broader legacy runtime suite has unrelated pre-existing asset-version failures, luci-dashboard was restarted, and / /board /ticket/4357 return 200. Closed MC-4357 and released MC-4343.

Controller re-closed stale reopen artifact: MC-4357 had already been gated live and pushed at 3d12462fe2f40e0aab42760c1bd4c23b90afcc64; current verification still shows that SHA is an ancestor of origin/slot2/mc-MC-4327 and MC health is healthy. The row was reopened without a live tmux/runtime by a stale signal/old API comment, so I quarantined the stale signal (/home/lucienne/workspace/state/mc-signals/MC-4357.json.controller-reclosed-2026-05-28T172240p0200) and restored terminal done metadata. Human input required: no.
