Context for Review​

Background​

This ADR was created in response to the complete failure of our bash-based export watcher infrastructure. During today's session, we discovered:

  • All 5 different export watcher implementations failed
  • Race conditions and incorrect directory monitoring
  • No proper state management or error handling
  • Critical export files were being missed

Solution Overview​

The ADR proposes integrating CODI2 (our unified CLI) with a new Rust-based monitoring service (codi-monitor) that will:

  • Replace all fragmented bash scripts
  • Provide reliable file monitoring and export watching
  • Integrate with CODITECT Server Hub (ADR-029)
  • Support both local and containerized environments
  • Use Unix domain sockets for IPC with TCP fallback

Critical Integration Points​

  1. CODI2 Commands: All monitoring through unified CLI
  2. IPC Communication: MessagePack over Unix/TCP sockets
  3. Shared Storage: SQLite with WAL mode
  4. Server Hub: Batch log shipping with JWT auth
  5. Graceful Degradation: CODI2 works standalone if monitor is down

Review Criteria​

Please evaluate against the standard QA Review Guide v3.4 criteria:

Specific Review Questions​

  1. Integration Architecture: Is the IPC approach (Unix sockets + TCP) appropriate for our use case?
  2. Performance Targets: Are the latency (<1ms) and throughput (100k/s) targets realistic?
  3. Failure Handling: Is the graceful degradation strategy sufficient?
  4. Testing Coverage: Are we missing any critical test scenarios?
  5. Security: Are the IPC security measures adequate?
  6. Compatibility: Will this integrate smoothly with existing CODI2 commands?

Expected Timeline​

  • Review Requested: 2025-09-28
  • Target Completion: 2025-09-29
  • Implementation Start: Upon approval

Notes for Reviewer​

This ADR is critical for fixing our monitoring infrastructure. The export watcher failures discovered today are unacceptable for an "essential script" that must always work. The proposed solution completely replaces the fragile bash scripts with a robust Rust implementation.

Please pay special attention to:

  • The integration protocol between CODI2 and codi-monitor
  • The dual-write pattern for local resilience
  • The test strategy for failure scenarios
  • The migration path from current broken state

Approval Chain​

  • QA Review
  • Technical Architecture Review
  • Security Review
  • Final Approval
