Don’t trust completions—verify them. Practical checklist:
- Review every line; reject custom crypto and non-constant-time code.
- Add unit tests, property tests, and fuzzing for edge cases.
- Run static analysis (gosec/clang-tidy/asan/ubsan) and dependency checks.
- Use vetted crypto libraries, pin versions, and require PR checklist items: entropy, side-channel resistance, error handling, secret zeroing.
- Limit Copilot to boilerplate/glue; require a human author for crypto logic.
