 **Daemon Behavior:**
 1. Runs at configurable interval (default: 5 minutes)
-2. Checks if active agents < MAX_CONCURRENT_AGENTS

-3. Picks 1-N pending items (configurable batch size)

-4. Forks PM session for each picked item
+   - Acquires lock to prevent duplicate processing
-5. PM decides whether to use `start` or `continue`
+   - Sources kugetsu-session.sh and calls `cmd_continue`
+   - `cmd_continue` handles worktree/session creation and forks dev agent from base session
+   - Updates queue item state to "notified"
+4. Uses per-issue locking to prevent race conditions
+5. Implements timeout for tasks that don't complete (marks as "error" after TASK_TIMEOUT_HOURS)

+## Version History
+
+### v0.2.3
+- **Queue daemon context drift fix** (issue #156): Daemon now sources kugetsu-session.sh and calls `cmd_continue` directly instead of forking PM session. This fixes context drift where daemon would lose track of task state.
+- **Daemon locking**: Added per-issue locking to prevent race conditions when multiple daemon instances run.
+- **Timeout handling**: Tasks that don't complete within TASK_TIMEOUT_HOURS are marked as "error".
