verify-deployment

Verify that a deployed environment actually delivers what the contract promised. Routes per-platform — Playwright against a URL for web; Flutter integration tests; native iOS (xcodebuild) / Android (gradlew) with Firebase Test Lab; API smoke tests for backend — plus telemetry sampling (Firebase/Crashlytics/Sentry). Invoked by /verify-deploy or the verify-deploy.yml workflow. Reports per-AC pass/fail with a canary-readiness verdict.
