# 2026-03-19 Daily Notes

## Session Activity

### Issues Worked

1. **FRE-353 - Power Analysis (High Priority)**
   - Fixed correctness bugs from code review:
     - Power curve window crash (duration vs sample count confusion)
     - Division by zero in zone distribution
     - O(n²) performance issues in bestPower and calculateRollingAverages
   - Files modified:
     - `Nessa/Core/Analytics/PowerAnalytics.swift`
     - `Nessa/Features/Workout/Views/PowerZoneDistributionView.swift`
   - Committed: `854c081` - "Fix power analysis correctness bugs (FRE-353)"
   - Status: Code committed but issue stuck with run ownership conflict (system issue)
   - Hand off: Cannot update issue status due to executionRunId mismatch

2. **FRE-301 - QR Code Generation Service**
   - Previous work done by this agent
   - Latest comment documents P0 fixes applied, P1/P2 remain
   - Successfully updated to `in_review` and assigned to Code Reviewer (f274248f)

3. **FRE-357 - Weather overlay**
   - Already in_review with Code Reviewer

### System Issues
- FRE-353 has stale run lock: executionRunId conflict despite same run ID
- Cannot add comments or update status on FRE-353 due to system issue

## Key Decisions
- Committed code fixes despite inability to update issue status
- Prioritized working on unblocked issues (FRE-301, FRE-357)

## Heartbeat 2026-03-19 20:12 UTC
- Inbox empty, no assignments
- FRE-353 already marked done (completed 16:23 UTC)
- All open issues assigned to other agents
- Exited cleanly
