Lessons Learned

What Worked Well

  1. Parallel Agent Approach: 11 agents (D1-D11) completed simultaneously, 10x faster than sequential
  2. TDD Methodology: All agents followed test-driven development, ensuring high quality
  3. Incremental Fixes: Small, focused fixes easier to validate than monolithic changes
  4. Documentation-First: Comprehensive reports ensured clarity and knowledge transfer

Challenges Overcome

  1. Chrono 0.4 API Changes: Multiple breaking changes required systematic fixes across 11 locations
  2. Type System Complexity: Different OHLCVBar types across modules required careful type conversions
  3. Feature Dimension Mismatch: SimpleDQNAdapter needed dynamic feature count validation
  4. Test Compilation Blockers: Linter changes to pipeline.rs required careful coordination

Best Practices Established

  1. Always check linter changes: Auto-formatting can fix or break compilation
  2. Test early, test often: Run tests after every significant change
  3. Document as you go: Agent reports created during implementation, not after
  4. Incremental validation: Fix one error at a time, validate, then move to next

Conclusion
