- Metrics - Tests, coverage, performance
- Technical Decisions - Key choices made
- Lessons Learned - What worked, what didn't
- Next Steps - Follow-up work identified
Sprint 4.22 - Phase 6 Part 1
Duration: November 2025 (Week 1-2) Focus: TUI Framework Foundation
Goals
- Implement ratatui-based TUI framework
- Achieve 60 FPS rendering capability
- Create core widget system
- Establish event handling architecture
Achievements
| Metric | Target | Actual |
|---|---|---|
| FPS | 60 | 60 |
| Event throughput | 5K/sec | 10K+/sec |
| Widget tests | 50 | 71 |
| Memory overhead | <50MB | ~30MB |
Technical Decisions
- ratatui 0.29 - Modern TUI library with good async support
- Event bus architecture - Decoupled widget communication
- Immediate mode rendering - Simplified state management
Lessons Learned
- Event batching critical for performance
- Widget composition simplifies testing
- Async rendering requires careful state management
Sprint 5.X - Rate Limiting V3
Duration: October 2025 (Week 3) Focus: Adaptive Rate Limiting
Goals
- Implement adaptive rate control
- Minimize performance overhead
- Support multiple rate limiting strategies
- Integrate with timing templates
Achievements
| Metric | Target | Actual |
|---|---|---|
| Overhead | <5% | -1.8% |
| Accuracy | ±10% | ±5% |
| Strategies | 3 | 4 |
| Tests | 30 | 45 |
Technical Decisions
- Token bucket algorithm - Smooth rate control
- Adaptive feedback - Responds to network conditions
- Per-target limits - Granular control
Lessons Learned
- Rate limiting can improve performance (reduced retries)
- Adaptive algorithms need careful tuning
- Integration with timing templates essential
