Description

MC-4612

Follow-up from MC-4607 council. The session-history rail row dict has no close_reason, so MC-4607 maps ALL non-live runtime states to neutral 'History' (avoids a false-red wall from reaped tmux runtimes, close_reason=tmux_session_missing). Cost: a genuinely crashed runtime no longer shows any failure cue in the rail. Fix: add close_reason (and/or a terminal chat status) to the recent_threads row builder in models.get_home_zones / _home_thread_runtime_summary, then in dashboard_v2.html show 'Failed' only when close_reason indicates a real error (not tmux_session_missing/reaped/stopped). Restores real signal without the wall. Council: Gemini+GLM+Codex flagged the signal loss; Opus called current state an acceptable honest tradeoff.

Controller picked this up from the stuck backlog and dispatched a direct Control Room worker. Gate: Build → focused regression/tests → commit+push → controller review. Runtime: tmux cr-MC-4612, pid 2574309, worktree /home/lucienne/workspace/state/control-room-worktrees/mc-4612-home-rail-close-reason. Expected check-in: 2026-06-03T06:22:39.967339+02:00

Controller recovered completed direct-worker output after tmux/session harvest marked it failed. Evidence: - Worker log /tmp/mc-4612-claude-output.log contains DONE and commit affa229. - Branch cr/mc-4612-home-rail-close-reason was pushed. - Controller test run: `python3 -m pytest tests/test_mc4612_home_rail_close_reason.py tests/test_mc4123_home_v2.py -q` → 39 passed. - Fast-forward merged affa229 onto master and pushed origin/master. - Restarted luci-dashboard.service and smoked local + Tailscale `/` → HTTP 200. This ticket is closed; the failed harvest/recovery gap is now included in MC-4631.
