# Phase 01 Plan 03: Bot Command Integration Summary

**Integrated SessionManager and ClaudeSubprocess into Telegram bot with /new, /session, /archive commands and session-aware message routing**

## Performance

- Duration: 15 min
- Tasks: 2 (1 auto, 1 human-verify)
- Files modified: 1
- Commands added: 3
- Commits: 1 task + 7 orchestrator fixes

## Accomplishments

### Primary Features
- Added `/new` command to create and activate new sessions
- Added `/session` command to list and switch between sessions
- Added `/archive` command to compress and cleanup sessions
- Session-aware message routing:
  - No active session → prompts user to create or select
  - Active session → routes message to Claude subprocess
- Callback-based response delivery from subprocess to Telegram
- All existing bot commands preserved and working

### Quality & Debugging
- Non-blocking message handler (block=False) prevents bot freezes
- [TIMING] profiler instrumentation added for response latency debugging
- Async callback factory pattern decouples subprocess from session manager
- Proper SIGTERM signal handling (subprocess completion, not crashes)

## Task Completion

| Task | Name | Status | Commit |
|------|------|--------|--------|
| 1 | Add /new and /session commands | Complete | 3a62e01 |
| 2 | Human verify session flow | Complete | approved |

## Orchestrator Fixes Applied

| Commit | Type | Description |
|--------|------|-------------|
| d08f352 | fix | Import collision: telegram/ shadowed pip telegram package |
| 3cc97ad | fix | SIGTERM not treated as crash + async callbacks in crash handler |
| a27ac01 | feat | Add /archive command for session cleanup |
| faab47a | refactor | Restructure personas (default, homelab, brainstorm, planner, research) |
| 3fec4ed | fix | Update persona models to use aliases not versions |
| 2302b75 | fix | Fix persona settings nested under "settings" object |
| (pending) | perf | [TIMING] profiler instrumentation for response latency |

## Decisions Made

1. **Import Strategy:** Sibling imports (`from session_manager import`) instead of package imports to avoid shadowing the pip `telegram` package
2. **Process Lifecycle:** Fresh `claude -p` process per message turn for Phase 1 simplicity (not persistent)
3. **Session Activation:** Creating a session does not activate it; must use /session command (prevents accidental switches)
4. **Archive Format:** tar+pigz compression for session archives stored in `sessions_archive/`

## Known Gaps & Deviations

### Gap: Non-persistent Subprocess Model
The implementation spawns a fresh `claude -p` process per message turn. This contradicts the design decision:
- **Original goal:** "Switching sessions suspends (doesn't kill) current process — stays alive"
- **Current behavior:** Fresh process each turn
- **Impact:**
  - ~1s CLI startup overhead per message
  - No session continuity without --continue flag
  - Every message is a cold-start
  - No streaming responses or typing indicators

**Status:** Known Phase 1 simplification. Should be addressed in Phase 2 with persistent process model.

### Auto-fixed Issues (Not in Original Plan)

1. **Import Collision** (d08f352)
   - telegram/ directory __init__.py shadowed pip telegram package
   - Fixed: Restructured imports to use sibling module pattern

2. **SIGTERM Handling** (3cc97ad)
   - SIGTERM interpreted as crash during service restarts
   - Fixed: Properly distinguished between SIGTERM (clean exit) and actual crashes

3. **Persona Settings Bug** (2302b75)
   - Persona settings nested under "settings" object, not being read
   - Fixed: Flattened settings structure in persona models

4. **Hardcoded Model Versions** (3fec4ed)
   - Model versions from training data instead of using aliases
   - Fixed: Updated to use model aliases (default: claude-opus-4-5-20251101)

## Deviations Summary

**Auto-fixed (Rule 2 - Critical):** 4 issues fixed automatically (import collision, signal handling, persona settings, hardcoded versions)

**Planned Gaps:** 1 known gap documented (non-persistent processes → Phase 2)

## Issues Encountered

- Subprocess model flag not being passed to Claude (persona settings nesting)
- Response latency ~10s (API wait + no streaming feedback)
- Fresh process overhead ~1s per message turn

## Next Phase Readiness

**Status:** Phase 1 Complete, Phase 2 Ready (with known gaps documented)

**Readiness assessment:**
- Session management: ✓ Complete
- Subprocess integration: ✓ Complete
- Bot commands: ✓ Complete
- Message routing: ✓ Complete

**Blockers for Phase 2:**
- Persistent process model (replace one-shot `claude -p`)
- Streaming responses needed for UX (typing indicators)
- Message batching strategy for long responses
- Response latency profiling and optimization
