Systematically verify documentation claims against codebase reality. Use when auditing docs, before releases, after refactors, or when documentation drift is suspected. Two-pass approach with pattern expansion ensures comprehensive detection of false claims, dead references, and gaps.

Use when about to commit, create a PR, or declare work complete — after verification-before-completion confirms tests pass but before code ships. Catches security vulnerabilities, logic errors, and business rule bugs that slip through despite passing tests.
