MC-4162

Created as a parked bug ticket from Elmar report. Deliberately status=waiting on create to avoid the MC-4159 auto-pickup race; do not release to todo until ready to run the gated fix loop.

RUNTIME TERMINAL STATE (MC-3482 contract) status: warning summary: Live ticket runtime timed out without a harvestable verdict; parked for automatic runtime recovery. root_cause: harvest timeout — no DONE/REVIEW/QUESTION verdict; write-back preserved substantive transcript tail safe_retry: Runtime was killed and the ticket was returned to todo for a fresh Luci-owned retry; no human input is needed. stop_condition: After the configured retry limit, leave the ticket blocked for operator inspection instead of looping. human_input_required: no next_actions: - Pickup will start a fresh runtime from MC history. - Inspect the pane log artifact only if the retry fails again. artifacts: - ticket:MC-4162 - pane_log:/home/lucienne/workspace/logs/mc-MC-4162.tmux.log

Luci picking up this ticket (background worker).

Ticket picked up by Luci via MC dispatcher. MC-4162: Bug: deferred waiting tickets can still be auto-picked/executed Work this ticket in the live tmux runtime. Use DONE:, REVIEW:, or QUESTION: when you need MC to reflect the next state.

Fixed MC-4162: waiting/blocked tickets now reconcile active runtimes and stale worker completion signals are quarantined. Commits pushed: mission-control bcc98be, luci-workspace 8863a3f3.

Closed (orchestrator). Both commits on master + new tests green: - mission-control bcc98be (+580/-6): models.py +160 (waiting/blocked lifecycle reconcile), ticket_runtime.py +19, app.py +17, runtime-architecture-refresh.md +12, NEW test_mc4162_waiting_lifecycle.py +378. 8/8 tests pass. - workspace 8863a3f3 (+320/-11): mc_pickup.py +185 (stale worker completion signal quarantine), test_mc_pickup_regressions.py +135 (4 new passing tests verified by A/B diff). 8 pre-existing failures in test_mc_pickup_regressions.py are unrelated regression debt (confirmed pre-MC-4162 commit had identical 8 failures). Worker correctly flagged 'known unrelated' for test_workflow_idempotency.py too. ACs covered: deferred waiting/blocked tickets now reconcile active runtimes; stale REVIEW/DONE/QUESTION signals from prior episodes are quarantined; lifecycle docs updated. UA sign-off (runbooks/ua-signoff-gate.md): n/a — backend lifecycle hardening, no user surface. Verdict: PASS

[controller release · 2026-05-26T13:05:32+02:00] This is Luci-owned technical hardening, not a human blocker. Releasing to todo for Codex pickup when capacity is available.

[controller repair · 2026-05-26T13:07:21+02:00] Dispatcher reported HTTP 409 after starting the tmux runtime, leaving the ticket row in todo with failure_reason. Runtime ledger shows the prompt was injected and session is running; normalized ticket to in_progress. Expected check-in: 2026-05-26T13:52+02:00.
