+## Inner Loop Tracking
+
+When Claude Code runs inside a claudeman session, it may run its own Ralph Wiggum loops or use the TodoWrite tool. Claudeman automatically detects and displays this internal state.
+
+### What's Detected
+
+- **Completion Phrases**: `<promise>COMPLETE</promise>`, `<promise>TIME_COMPLETE</promise>`, etc.
+- **Todo Items**: Checkbox format (`- [ ]`/`- [x]`), indicator icons (`☐`/`◐`/`✓`), status parentheses
+- **Loop Status**: Cycle counts, elapsed time, loop start/completion
+
+### UI Display
+
+A collapsible panel appears below session tabs when inner state is detected:
+- **Collapsed**: Shows loop status and task summary (e.g., "🔄 Loop: TIME_COMPLETE (2.3h) | Tasks: 3/5")
+- **Expanded**: Shows full todo list with status indicators
+
+### API
+
+```bash
+# Get inner state for a session
+curl localhost:3000/api/sessions/:id/inner-state
+```
+
+Returns:
+```json
+{
+  "success": true,
+  "data": {
+    "loop": { "active": true, "completionPhrase": "COMPLETE", "cycleCount": 5, "elapsedHours": 2.3 },
