Build the test grid that makes AI-written code safe — traceability from spec UC ids to tests, density floors per changed symbol, and a hard ban on skipping or weakening tests to get green. Use when deciding how many tests a change needs, wiring acceptance criteria to test names, generating tests for agent-written code, or when a suite is green but trust in it is low.
