+# Race Condition Agent - Weekly Run
+
+**Date:** 2026-02-22
+**Agent:** race-condition-agent
+**Status:** Completed
+
+## Summary
+Executed weekly race condition audit.
+
+### Findings
+- **Critical:** Identified and fixed an initialization race condition in `js/app.js` where `accessControl` lists were being loaded asynchronously without the application waiting for them.
+
+### Actions Taken
+- Refactored `_initAccessControl` in `js/app.js` to return a Promise.
+- Updated `initializeDataAndSession` to `await` the access control initialization.
+- Verified changes with unit tests (`npm run test:unit`) and linting.
+- Produced report: `artifacts/race-condition/weekly-race-condition-report-2026-02-22.md`.
+
+## Next Run Focus
+- PlaybackService state management.
