Controller normalization: the previous blocked state was a technical operator runtime-dispatch race, not a human blocker. Parked behind the current control-plane chain (MC-4383 -> MC-4371 -> MC-4357); resume this live smoke after the harvest/landing chain is clear. No Elmar input required.

Controller recovery handoff after MC-4357 closed live. MC-4343: Prove Controller Reviewer Tessa loop with live smoke Scope: After import and flag fixes, prove fail-to-retry, pass-to-Tessa, Tessa-issues-to-retry, and Tessa-approved-to-close using a throwaway smoke/harness. Do not use a production ticket. Context: MC_ORCH_REVIEW_RETRY=1 and MC_ORCH_TESSA_GATE=1 are live in luci-dashboard and luci-scheduler. MC-4357 is now verified done/live (commit 3d12462) and dashboard was restarted. The previous blocked state was a technical runtime dispatch 409 race, not human input. Work this ticket in the live tmux runtime. Use DONE:, REVIEW:, or QUESTION: when you need MC to reflect the next state.

Live smoke proved all 4 Controller→Reviewer→Tessa transitions (fail→retry, pass→Tessa, Tessa-issues→retry, Tessa-approved→close); throwaway isolated-DB harness committed dcf99f1, no production ticket touched.

Workflow action `complete` applied. Work completed.

Shadow reviewer verdict: UNCERTAIN. Needs human decision. Reasons: The diff introduces a comprehensive throwaway smoke test script (`smoke_tessa_loop.py`) that explicitly covers the four required transitions (fail-to-retry, pass-to-Tessa, Tessa-issues-to-retry, Tessa-approved-to-close) using dependency-injected LLM calls and an isolated DB. However, the diff is truncated at line 289, cutting off the implementation of transition 4 (Tessa-approved-to-close) and the main execution block. Additionally, the worker's comments indicate repeated runtime failures (HTTP 409 race conditions, tmux session closures) and manual interventions, raising questions about whether the test actually runs successfully to completion in the live environment. Without seeing the full diff or actual test execution results, it's unclear if the smoke test genuinely proves all four transitions work end-to-end. Gaps: - Diff is truncated — transition 4 (Tessa-approved-to-close) implementation and main execution block are missing from view - No evidence of successful test execution (no test output, no CI run, no exit code 0 confirmation) - Worker comments describe runtime failures (409 race, tmux closures) that suggest the smoke may not have actually completed successfully - Cannot verify if the dependency-injected LLM approach truly exercises the real controller modules as claimed

[follow-up] 0 min past expected check-in (2026-05-28 15:29:59 UTC).

Controller repair: downstream slice explicitly parked behind active slice MC-4342; not Elmar/Lucienne input.

Controller normalization after full pending audit: Tessa-loop smoke cannot start until MC-4342 flags are actually live after restart.

Released from MC-4342 blocker: gate flags are now live in luci-dashboard and luci-scheduler. Ready for throwaway live smoke.

Controller note: MC-4342 flags are live, but the smoke dispatch hit a ticket-runtime send race (409 while runtime status=running), then the recovery loop closed the tmux session after retry limit. This is an operator/runtime recovery issue, not an Elmar blocker.

Controller release: MC-4357 is verified done/live, and MC-4341/MC-4342 are already done. Returning this live-smoke blocker to todo for pickup. Expected check-in: ~15 minutes.

Controller row-drift repair: pickup returned HTTP 409 after spawning tmux mc-MC-4343, but the pane and runtime row are live. Normalized ticket back to in_progress and cleared the transient tmux_spawn_failed field.

Controller recovery: the automatic pickup path repeatedly hit the runtime-send 409 race after spawning and then blocked the ticket. Clearing the technical blocked state and manually starting the live runtime from the controller; no human input required.

Controller gate passed and closed: the shadow-review uncertainty was a truncated-diff artifact, not a human blocker. Verified commit dcf99f1 on origin/slot2/mc-MC-4343, inspected the full 289-line scripts/smoke_tessa_loop.py including transition 4 and main(), and ran `python3 scripts/smoke_tessa_loop.py` in the ticket worktree: all four Controller→Reviewer→Tessa transitions passed (fail→retry, pass→Tessa, Tessa-issues→retry, Tessa-approved→terminal/no re-bounce). Human input required: no.

Luci Operator corrected this ticket: worker completion evidence shows `DONE` with shipped/commit proof, so this is no longer blocked or awaiting review.
