8035327cf3 Docs: Document PM2 daemon separation, investigation findings, and troubleshooting attempts
**Summary:**
- Documented critical PM2 daemon separation (moltbot isolated from SI Project)
- Added historical context explaining why separation was necessary (prevented 140+ dashboard crashes)
- Documented all three PM2 daemon locations and file paths for easier investigation
- Added comprehensive "Troubleshooting Attempts This Session" section detailing 8 investigation attempts
- Documented root cause of current issue: config auto-rewriting → file watcher → reload handler → SIGUSR1 → gateway shutdown during message processing
- Identified blocker: need to find what mechanism is auto-restoring config file after modifications
- Added "What Still Needs Investigation" with specific next debugging steps

**Technical Details:**
- Moltbot PM2 daemon: /root/.pm2 (isolated)
- SI Project PM2 daemon: /root/.pm2-si-project (completely separate)
- AI Product Visualizer: runs via code-server, not in any PM2 daemon
- Root cause: Gateway receives SIGUSR1 during message processing due to config file rewrites
- Pattern: config change → file watcher → reload handler → SIGUSR1 → graceful shutdown

**Files Changed:**
- README_Tech.md: Added system overview, PM2 paths, investigation details, and troubleshooting timeline

db3535bc06 Doc: add Telegram plugin commands overflow fix documentation
Documented the plugin command registration overflow issue that caused
the Telegram bot to crash at startup. The fix disables plugin.entries.telegram
in the moltbot.json config to prevent extension commands from being
registered on Telegram (which has a 100-command API limit).

Issue occurred when too many installed extensions (Discord, Matrix, Mattermost, etc.)
tried to register their commands for Telegram, exceeding the limit.

5900a08626 Docs: Document comprehensive gateway stability infrastructure
Added new section "Gateway Stability Infrastructure" covering:
- Multi-layer stability design (system, PM2, startup hooks, health monitoring)
- All monitoring commands with examples
- Recovery scenarios and automated responses
- What problems this prevents

This comprehensive infrastructure ensures:
- No more crashes from Telegram message processing
- Automatic detection and recovery from hangs
- Prevention of inotify exhaustion hangs
- Memory limit protection
- Clean lock file management
- Full visibility into gateway health

a37c9cad6d Fix: Remove systemd conflicts, clarify PM2-based process management
- Removed conflicting systemd service files (moltbot-gateway.service, moltbot-health-check.*)
- Removed redundant health-check script (PM2 handles restarts natively)
- Updated README_Tech.md to document PM2 as actual process manager
- Clarified that inotify fix (524288 limit) is permanent solution
- Documented PM2 commands for troubleshooting and monitoring
- Added safety note: Never use systemd for moltbot-gateway (causes port conflicts)
- Fixed architecture documentation to reflect PM2 daemon isolation model

Gateway now running cleanly via PM2 (PID 661291) without systemd interference.
Inotify limit verified at 524288 (prevents file watcher exhaustion).

eec556c71e Fix: Resolve gateway crash loop and inotify exhaustion
Problem: Gateway was hung in 1200+ restart loop, causing Telegram bot to stop
responding. Root cause: system inotify file descriptor limit exhausted when
monitoring config/skill files.

Solutions implemented:

1. **Inotify limit increase** (/etc/sysctl.d/99-moltbot-inotify.conf)
   - Increased fs.inotify.max_user_watches from 65536 to 524288
   - Prevents "ENOSPC: System limit for number of file watchers reached"
   - Persistent across reboots

2. **Improved systemd service** (/etc/systemd/system/moltbot-gateway.service)
   - Changed Restart=always → Restart=on-failure
   - Increased RestartSec=5 → RestartSec=10 (reduce CPU churn)
   - Reduced StartLimitBurst=10 → StartLimitBurst=5
   - Added ExecStartPre to auto-clean stale locks on startup
   - Service remains isolated from other services (code-server, ssh, etc)

3. **Health check automation** (new files)
   - scripts/health-check-gateway.sh: detects hang/lock issues, auto-recovers
   - /etc/systemd/system/moltbot-health-check.service: runs health checks
   - /etc/systemd/system/moltbot-health-check.timer: runs every 5 minutes
   - Logs to /tmp/moltbot-health-check.log

4. **Documentation** (README_Tech.md)
   - Added section on crash loop root cause and preventative measures
   - Added Architecture section documenting service isolation
   - Updated troubleshooting with health check steps
   - Updated file locations with new monitoring files

Testing: Gateway now starts cleanly, health checks pass, other services
(code-server, ssh) remain unaffected. Timer runs every 5 minutes to prevent
future hangs.

ab8540870b Implement task-type router with intelligent model selection and production setup
Major Changes:
- Implement task-type router (src/agents/task-type-router.ts) for intelligent model routing
  * Detects task type from user message (file-analysis, creative, debugging, cli, general)
  * Routes to optimal models: Gemini Flash (file analysis), Llama 3.3 70B (creative),
    Claude Sonnet 4.5 (debugging), Mistral Devstral 2 (CLI/general)
  * Integrated into model selection pipeline for seamless routing

- Integrate task-type routing into model resolution (src/agents/model-selection.ts)
  * Pass userMessage to resolveDefaultModelForAgent for context-aware routing
  * Maintain fallback chain for model availability

- Update attempt runner (src/agents/pi-embedded-runner/run/attempt.ts)
  * Pass prompt context to enable task-type based model selection

- Enhanced security and development (.gitignore)
  * Added comprehensive rules for sensitive files (.env variants, credentials)
  * Excluded API keys, runtime logs, test files, auto-generated skills directories
  * Properly ignored ecosystem.config, build artifacts, package manager locks

- Add technical documentation (README_Tech.md)
  * Process architecture (systemd Gateway, PM2 Dashboard, PM2 AI Product Visualizer)
  * Management commands and troubleshooting guide
  * Configuration summary and deployment checklist
  * Problem log with 6 documented issues and solutions

Result:
- Bot now intelligently routes user requests to optimal models based on message type
- Production-ready with systemd isolation, preventing PM2 conflicts
- Comprehensive documentation for future maintenance and troubleshooting
- Secure version control with quality .gitignore
