 **CI-cloud-first workflow (recommended):** On constrained hardware run **`pnpm run lint && pnpm run i18n:check && pnpm run typecheck`** locally, then push and let CI handle coverage, E2E, Lighthouse, and Stryker. Authoritative numbers come from CI artifacts (Codecov, JUnit). After CI goes green, update the README badges and `AUDIT.md` quality-gate line from the reported metrics. See **[`docs/CI.md`](docs/CI.md) § Cloud CI-first vs local development** for the full post-merge doc-update checklist.
