Performance Readiness Review
Baseline before rollout:
- SchoolContext resolution overhead
- student list response time
- scanner process latency
- payment record/edit latency
- recipient preview generation time
- bulk send queueing time
- report run time
- export generation time
Known risks:
- unscoped queries
- N+1 resources
- large recipient previews
- large exports
- scanner latency during active check-in
- extension table joins in reports
Correctness wins first. Fast wrong answers are still wrong, just with better posture.
