From def96a1b6efc0cdc78999e42249905e96af4a0ad Mon Sep 17 00:00:00 2001 From: Jeremy McSpadden Date: Mon, 16 Mar 2026 17:36:04 -0500 Subject: [PATCH 1/2] fix: write auto.lock at startup and detect remote sessions in dashboard (#723) Three bugs caused /gsd status to show "No unit running" while auto mode was actively executing in another terminal: 1. auto.lock was only written during unit dispatch (after newSession()), not at auto-mode startup or resume. Any cross-process check between startup and first dispatch would find no lock file. 2. The dashboard read only the in-memory `active` flag, which is always false in a different process. It never checked auto.lock for cross-process detection. 3. The triage dispatch path wrote the lock to `basePath` (worktree) instead of `lockBase()` (project root), making it invisible to other terminals checking the project root. Changes: - Write initial auto.lock immediately in startAuto() and on resume - Add cross-process detection in getAutoDashboardData() via auto.lock - Add remoteSession field to AutoDashboardData for cross-process info - Update dashboard overlay to show remote session status and unit info - Fix triage dispatch to use lockBase() instead of basePath - Add 11 tests covering lock creation, cross-process detection, and stale lock handling --- .../extensions/gsd/auto-dashboard.ts | 2 + src/resources/extensions/gsd/auto.ts | 10 +- .../extensions/gsd/dashboard-overlay.ts | 18 +- .../gsd/tests/auto-lock-creation.test.ts | 185 ++++++++++++++++++ 4 files changed, 212 insertions(+), 3 deletions(-) create mode 100644 src/resources/extensions/gsd/tests/auto-lock-creation.test.ts diff --git a/src/resources/extensions/gsd/auto-dashboard.ts b/src/resources/extensions/gsd/auto-dashboard.ts index 616e64229..1fcd98a4d 100644 --- a/src/resources/extensions/gsd/auto-dashboard.ts +++ b/src/resources/extensions/gsd/auto-dashboard.ts @@ -41,6 +41,8 @@ export interface AutoDashboardData { profileDowngraded?: boolean; /** Number of pending captures awaiting triage (0 if none or file missing) */ pendingCaptureCount: number; + /** Cross-process: another auto-mode session detected via auto.lock (PID, startedAt) */ + remoteSession?: { pid: number; startedAt: string; unitType: string; unitId: string }; } // ─── Unit Description Helpers ───────────────────────────────────────────────── diff --git a/src/resources/extensions/gsd/auto.ts b/src/resources/extensions/gsd/auto.ts index 87ef155f4..41d585f32 100644 --- a/src/resources/extensions/gsd/auto.ts +++ b/src/resources/extensions/gsd/auto.ts @@ -786,6 +786,9 @@ export async function startAuto( pausedSessionFile = null; } + // Write lock on resume so cross-process status detection works (#723). + writeLock(lockBase(), "resuming", currentMilestoneId ??
