- Added JSDoc and inline comments to `src/services/memory/index.js` to clarify module flow and internal invariants.
- Fixed a race condition in `performSave` where `currentSavePromise` was cleared before the pending save was chained, potentially allowing concurrent writes.
- Created `docs/memory-service-index-overview.md` with high-level architecture.
- Verified changes with `npm test src/services/memory/index.js` and `npm run lint`.
- Updated `TEST_LOG` and `task-logs` to reflect the fix.
