# Phase 03 Plan 01: Idle Timer Foundation Summary
**Asyncio-based per-session idle timer with configurable timeout metadata and subprocess PID tracking**
## Performance
- **Duration:** 2 min
- **Started:** 2026-02-04T23:27:29Z
- **Completed:** 2026-02-04T23:29:00Z
- **Tasks:** 2
- **Files modified:** 3
## Accomplishments
- Created SessionIdleTimer class with asyncio timer management
- Extended session metadata to include idle_timeout field (default 600s)
- Added PID property to ClaudeSubprocess for process tracking
- Foundation ready for suspend/resume lifecycle implementation
## Task Commits
Each task was committed atomically:
1. **Task 1: Create SessionIdleTimer module** - `488d94e` (feat)
2. **Task 2: Extend session metadata and subprocess PID tracking** - `74f12a1` (feat)
## Files Created/Modified
- `telegram/idle_timer.py` - SessionIdleTimer class with reset(), cancel(), and activity tracking properties
- `telegram/session_manager.py` - Added idle_timeout to metadata, get_session_timeout() helper method
- `telegram/claude_subprocess.py` - Added pid property returning live process ID
## Decisions Made
- Default idle timeout: 600 seconds (10 minutes) - balances responsiveness with resource conservation
- Timer reset pattern: Cancel existing asyncio task and create new one (clean slate approach)
- PID property returns None for terminated processes - prevents stale PID references
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
Ready for next plan (03-02: Suspend/Resume Implementation):
- Idle timer module complete and tested
- Session metadata supports timeout configuration
- Subprocess exposes PID for lifecycle tracking
- All imports verified, no blockers
