Testing

Use the repository gates rather than an old sprint checklist. Read the linked sections in CLAUDE.md for the invariant behind each command.

• make gate — formatting, lint, backend/frontend tests, and production build. See Before every commit — required checklist.
• make mutation-gate — mutates documented backend invariants and requires the named tests to fail. See The mutation gate — documented invariants, proven executable.
• make coverage-floor — runs coverage and rejects any unexecuted backend API handler. See The coverage floor — no handler may be entirely untested.
• npx playwright test — local end-to-end browser tests against the Pages runtime. See E2E tests.
• .github/workflows/edge-e2e.yml — edge authentication tests against a real Pages preview and scratch D1. See Edge E2E against a preview.

Run make install first when dependencies are not installed. Do not weaken a test, lint rule, or configuration to make a gate pass.
