Every template, every case, the checker’s actual verdict.
These are regression examples for CI, including expected catches and documented misses. For editable policy files and a guided setup, use the Policies page. Each row was produced by running the shipped checker at build time. “Matches” means the verdict equals the template’s documented expectation. Challenge templates show where their starter policy misses and the solution catches.
