Debug Session Management

Diagnose issues with Samara's message batching, session continuity, and task routing.

Session Architecture Overview

Messages arrive
      │
      ▼
SessionManager buffers (11 sec)
      │
      ▼
TaskRouter classifies tasks
      │
      ├─► Conversation ──► invokeBatch (with session)
      ├─► Webcam ────────► invokeIsolated (no session)
      ├─► WebFetch ──────► invokeIsolated (no session)
      └─► Skill ─────────► invokeIsolated (no session)

MessageBus sends response (with source tag)

Quick Diagnostics

1. Check Active Sessions

# View session state
cat ~/.claude-mind/state/sessions.json 2>/dev/null | head -30

# Check for stale locks
cat ~/.claude-mind/claude.lock 2>/dev/null
ls -la ~/.claude-mind/claude.lock

2. Check Message Batching

# Look for batch processing in logs
grep -E "(Buffering|batch|BatchReady)" ~/.claude-mind/system/logs/samara.log | tail -20

# Check batch sizes
grep "Processing batch of" ~/.claude-mind/system/logs/samara.log | tail -10

3. Check Task Classification

# Look for isolated vs session-based invocations
grep -E "(Isolated invocation|Resuming session|Starting new session)" ~/.claude-mind/system/logs/samara.log | tail -20

4. Check Group Chat Handling

# Group chat routing decisions
grep -E "(group chat|chatIdentifier|isGroupChat)" ~/.claude-mind/system/logs/samara.log | tail -20

# Look for routing warnings
grep -E "(WARNING.*group|looks like group)" ~/.claude-mind/system/logs/samara.log | tail -10

Common Issues

Scrambled Responses

Symptom: Responses seem to mix answers to different questions Cause: Multiple task types in same batch not properly isolated Check:

# Look for multiple task types in same batch
grep -B5 -A5 "Processing batch" ~/.claude-mind/system/logs/samara.log | tail -30

Fix: TaskRouter should classify and isolate parallel tasks

Session Not Resuming

Symptom: Context lost between messages Cause: Session ID not being passed correctly Check:

# Check session recording
grep "Recorded session" ~/.claude-mind/system/logs/samara.log | tail -10

# Check session retrieval
grep "Retrieved session" ~/.claude-mind/system/logs/samara.log | tail -10

Group Chat Messages Going to Wrong Chat

Symptom: Response sent to 1:1 instead of group Cause: isGroupChat flag not set correctly Check:

# Check routing decisions
grep "Routing decision" ~/.claude-mind/system/logs/samara.log | tail -10

Queue Not Processing

Symptom: Messages acknowledged but never answered Cause: TaskLock stuck or QueueProcessor not running Check:

# Check lock status
cat ~/.claude-mind/claude.lock

# Check queue processor
grep "QueueProcessor" ~/.claude-mind/system/logs/samara.log | tail -10

# Force release stale lock if needed
# rm ~/.claude-mind/claude.lock

Diagnostic Report

When debugging session issues, gather:

1. Recent batch processing logs
2. Session state file contents
3. Lock file status
4. Task routing decisions
5. Group chat routing decisions
