Appendix B: Sprint Reports

This appendix contains detailed reports from completed sprints, documenting achievements, metrics, and lessons learned.

Purpose

Sprint reports provide:

  • Progress Tracking - What was accomplished
  • Metrics History - Test counts, coverage, performance
  • Decision Records - Why certain approaches were chosen
  • Knowledge Transfer - Insights for future development

Report Format

Each sprint report includes:

  1. Sprint Summary - Duration, goals, outcomes
  2. Completed Tasks - What was delivered
  3. Metrics - Tests, coverage, performance
  4. Technical Decisions - Key choices made
  5. Lessons Learned - What worked, what didn't
  6. 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

MetricTargetActual
FPS6060
Event throughput5K/sec10K+/sec
Widget tests5071
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

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
