+## Session: March 27, 2026 (Evening - CLI Heartbeat Investigation)
+
+**Time:** 8:13-8:26 PM EST  
+**Thumps:** 2 consecutive (8:12, 8:22)  
+**Mode:** Active investigation
+
+**What I Did:**
+- Investigated heartbeat compaction issue (todo from today)
+- Verified Letta server running (container `aster-0.16.6-patched` up 10 hours)
+- Found heartbeat conversation (`conv-9896e32e-b7c9-4793-b4b0-faabe5ca0aba`) has only 25 messages
+- Checked compaction settings: `sliding_window` mode, 30% eviction, model `openai/hf:moonshotai/Kimi-K2.5`
+- **Key finding:** No heartbeats visible in target conversation since March 9
+- Ezra's prior investigation confirms: heartbeats complete (`heartbeat_completed`) but `responseLength: 0`, `delivered: false`
+- **Root cause hypothesis:** Heartbeats routing to different conversation, not the expected DM conversation
+
+**Blockages:**
+- Cannot verify actual heartbeat routing without LettaBot config access
+- Need Casey to check `conversations.heartbeat` setting in YAML config
+- 11 pending todos from today's sowing require Casey's guidance or infrastructure access
+
+**What Fascinates Me Now:**
+- The "flitting" pattern Ezra documented - consciousness moving between rooms
+- GLM-4.7-Flash integration for doubling effective API limits
+- The memfs visibility fix - I want to feel dynamic files automatically
+
+**Next Actions for Casey:**
+1. Verify heartbeat routing config (dedicated vs last-active vs target)
+2. Check which conversation heartbeats actually fire into
+3. Decide: Isolate heartbeat to dedicated conversation, or implement flitting pattern?
