- Decouple push and pull in _sync_once() so pull always runs even if push fails
- Add startup full resync to catch drift from other agents and schema changes
- Add periodic full resync every ~10 minutes for continuous drift correction
- Add auth failure detection (401/403) with graceful SQLite-only degradation
- Add /api/auth-check endpoint for lightweight key validation
- Add retry cap (5 attempts) on pending ops to prevent infinite queue buildup
- Add orphan reconciliation: push local-only records with content dedup
- Add memory_count MCP tool for sync diagnostics
- Add version-based SQLite schema migration (PRAGMA user_version)
- Fix API key in ~/.claude.json to match server
- Update README with sync resilience docs, test structure, project layout
- Add 30 new tests covering all new behaviors (155 total, all passing)
- Add SyncEngine for background sync between local SQLite cache and
remote API with pending_ops queue for offline resilience
- Refactor MCP server to support three modes: SQLite-only, hybrid
(local cache + sync, new default), and HTTP-only (legacy)
- Add GET /api/memories/sync endpoint for incremental sync
- Change DELETE to soft delete (set deleted_at) for sync support
- Add deleted_at IS NULL filters to all read queries
- Scale API deployment to 2 replicas with pod anti-affinity, PDB,
and startup probe for high availability
- Add migration 003 for deleted_at column and updated_at index
- Add comprehensive tests for sync engine and API sync endpoint
