Drive development with tests by writing a failing test before implementing code, and reproduce bugs with tests before fixing them.

Enforces running verification commands and confirming output before claiming work is complete, fixed, or passing, to prevent false success claims.

Prove a feature works by delegating verification to an independent sub-agent that drives the real app, then open a pull request with the proof.
