Subject: [PATCH] auto-claude: subtask-1-1 - Confirm root cause by reading
 task-log-service.ts

Verified three root causes by reading actual source files:
1. RC1 CONFIRMED: mergeLogs() oscillation at lines 134-139 - condition falls back to
   main logs when worktree coding phase resets to pending during agent retry
2. RC2 CONFIRMED: Stale cache emitted in startWatching() polling loop (lines 329-413)
   when JSON parse fails mid-write, stale cache is emitted as logs-changed
3. RC3 NOTE: useTaskDetail.ts onTaskLogsChanged already uses additive setExpandedPhases
   pattern (lines 256-260) - fix appears already applied, subtask-2-3 should verify

Investigation complete - findings documented in build-progress.txt.
No code changes in this investigation-only subtask.
