# Sprint Summary: Hookbug-Windows-Reliability

**Sprint Period**: None to 2026-03-14
**Duration**: 1 days
**Total Cards Completed**: 7
**Contributors**: CAMERON

## Executive Summary

Fixed Windows hook reliability: eliminated MediaPlayer/PresentationCore deadlock by delegating audio to detached win-play.ps1 process with CLI player fallback chain, added 8-second safety timeout, and implemented atomic state writes with retry-on-read across both platforms.

## Lessons Learned

### What Went Well 
- Clean sequential execution — Phase 1 (async audio) laid foundation for Phase 2 (atomic state)
- Pester tests caught stale assertion after merge, caught before review
- Two backlog cards captured for non-blocking tech debt

### What Could Be Improved 
- No metrics parser available on Windows — had to log agent metrics manually

## Next Steps

- [ ] Add diagnostic logging for silent audio failures (card z5xm5k)
- [ ] DRY up peon.sh state helpers and optimize first-run read path (card lyq5ta)
