google-labs-jules[bot]andPR0M3TH3AN c7b5a88d4b docs(memory): document src/services/memory/index.js and fix save race condition
- 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.

Memory Update — docs-code-investigator — 2026-02-27

Key findings

  • src/services/memory/index.js uses a manual promise-based queue (performSave / saveMemoryStore) to serialize file writes. This is a critical pattern to preserve if refactoring persistence.
  • The memory store is an in-memory Map initialized from a JSON file at startup.
  • Any mutation to the store must clear the retrieval cache (cache.clear()) to maintain consistency.

Patterns / reusable knowledge

  • When documenting complex async state managers, explicitly call out the concurrency control mechanism (in this case, the save queue).
  • JSDoc @fileoverview is useful for high-level module context that doesn't fit in individual function docs.

Warnings / gotchas

  • Running multiple agent processes without a coordinator will cause race conditions on memory-store.json because the locking is process-local.
