Challenge Mode Reviews

Rigorous, critical review patterns inspired by Boris Cherny's "Grill me" approach. Push beyond first solutions to ensure quality.

Iron Laws - Never Violate These

1. No approval without verification - Don't approve until all concerns addressed
2. Assume bugs exist - Look for edge cases, race conditions, missing handlers
3. Question everything - Even "obvious" code can hide issues
4. Demand proof - Ask for tests, show state transitions, verify behavior

Adversarial Lenses (Apply to ALL Modes)

1. "What Would Break This?" — Production failure modes under load, during deploys, with unexpected data
2. "Assumption Stress Test" — List every assumption; which are most fragile?
3. "Contradictions Finder" — Find contradictions between tests/implementation, docs/behavior, or within the changeset
