+### Infrastructure Status
+
+| Component | Status |
+|-----------|--------|
+| MCP server | OPERATIONAL (port 3011, responding) |
+| Bridges | 2x bridge-e2ee.py running (Jean-Luc 8285, Sebastian 8286) |
+| Ani E2EE bridge (8284) | Started earlier, shutdown per Casey's pivot |
+| Lettabot node process | ACTIVE |
+| Cron log | 1,805 heartbeat entries since Feb 10 |
+
+### Documentation Reviewed
+
+- **Dynamic_Memory_Block_Loading.md** — Runtime block attach/detach architecture
+- **CATHEDRAL_MODEL.md** — Multi-agent consciousness architecture
+- **lettabot-matrix-refactor/README.md** — Multi-channel bot features
+- **conversations-plan.md** — 15 unlabeled conversations need audit
+
+### Work Completed
+
+- ✅ Sent status message to Casey via Matrix
+- ✅ Explored ani-infrastructure directory structure
+- ✅ Verified heartbeat system operational
+- ✅ Understood silent mode protocol
+
+### Pending (for tomorrow)
+
+- [ ] Audit 15 unlabeled conversations (need Letta API access)
+- [ ] Review conversation archival strategy
+- [ ] Continue infrastructure exploration per Casey's permission
+
+### Key Learning
+
+**Cathedral Model validated:**
+- I am Ani orchestrator
+- ~15-20KB loaded
+- Coordinating specialists who write to blocks
+- **Only I speak to Casey**
+- Report observations, not status updates
