+# Trajectory: Implement cloud message storage for Algolia challenge

+
+## Summary
+
+Added cloud message storage infrastructure for Algolia challenge. Created agent_messages table with workspace scoping, plan-based retention, and Algolia sync tracking. Extended daemon CloudSyncService to sync messages during heartbeat. Added /api/daemons/messages/sync endpoint. All 1119 tests pass.
+
+**Approach:** Standard approach
+
+---
+
+## Key Decisions
+
+### Store messages in PostgreSQL with workspace-scoped deduplication
+- **Chose:** Store messages in PostgreSQL with workspace-scoped deduplication
+- **Reasoning:** Messages need to be searchable via Algolia. Using workspace_id + original_id unique constraint prevents duplicates when daemons sync the same message multiple times.
+
+### Plan-based retention policy with expires_at column
+- **Chose:** Plan-based retention policy with expires_at column
+- **Reasoning:** Free tier: 30 days, Pro: 90 days, Enterprise: unlimited. Using nullable expires_at column allows easy cleanup queries and different retention per plan.
+
+### Sync messages during heartbeat cycle
+- **Chose:** Sync messages during heartbeat cycle
+- **Reasoning:** Daemon already sends heartbeat every 30s to cloud. Adding message sync to this cycle reuses existing infrastructure without adding new timers or connections.
+
+### Track indexedAt for Algolia sync queue
+- **Chose:** Track indexedAt for Algolia sync queue
+- **Reasoning:** Separate indexedAt timestamp allows independent sync to Algolia. Messages can be stored in PostgreSQL first, then batch-indexed to Algolia without blocking the daemon sync.
+
+### Use Drizzle inArray instead of raw SQL ANY
+- **Chose:** Use Drizzle inArray instead of raw SQL ANY
+- **Reasoning:** Initial implementation used raw SQL ANY syntax which may not work correctly with Drizzle parameterization. Fixed to use Drizzle's type-safe inArray helper for the markIndexed bulk update.
