Performance and Resilience
Procedure
- Lighthouse plus web-vitals on key routes, mobile profile. Targets at p75: LCP ≤ 2.5s, INP ≤ 200ms, CLS ≤ 0.1 (thresholds).
- Throttle to Fast 3G and go offline mid-action. The UI shows state and recovers without data loss.
- API p50 and p95 per endpoint from HAR. Flag slow calls on the critical path.
- Long sessions: memory growth over 30 minutes, large data sets, and big transcripts (Nimbalyst heap issues).
- Failure injection (staging): kill a dependency, return 500 or timeouts, restart services. Watch customer-visible behavior.
- Load (approved only): ramp with k6 within the manifest's limits, and watch error rate and queue depth.
- Gateway limits: large headers and cookies on signed-in pages (pattern E4).
Exit criteria
A metrics table per route and endpoint, plus resilience scenarios with observed behavior.
