Write script to read from `agent_messages` table\n   - Write each session to `episodic/sessions/{id}.md`\n   - Create `{id}.summary.json` for each session\n   - Update session indexes\n\n2. **Export Workflows** (if any in PostgreSQL)\n   - Read from any workflow tables\n   - Append to `procedural/workflows.md`\n\n3. **Apply Minimal Schema**\n   - Run migration 002_minimal_schema.sql\n   - Verify tables dropped correctly\n   - Verify new tables created\n\n4. **Update Application**\n   - Deploy new code (Phase 1-4)\n   - Test file-based memory operations\n   - Verify PostgreSQL only stores metadata\n\n5. **Verification**\n   - Test conversation creation and flow\n   - Test session loading from files\n   - Test search across sessions\n   - Verify PostgreSQL metadata updates\n   - Monitor for errors in logs\n\n### Rollback Plan\n\nIf issues arise during migration:\n\n1. **Immediate Actions**\n   - Stop application\n   -
