Use when an end-to-end test file or folder (Playwright flows of any project whose GATES.md declares an e2e suite) must be audited for conformance before it is trusted — dispatched by the evaluator or qa-preflight after an e2e-test-writer correction, guard or new test, or run directly by a user. Generic — reads the project's profiles, folders, language, fixtures and data policy from its GATES.md. Read-only — never writes, fixes or runs tests.
