Overview

The self a finalize block runs on. Deliberately bare — no controller delegation — so a contract cannot grow request-state dependencies; its whole vocabulary is the hash it receives plus violate!.

Instance Method Details

#violate!(param, code) ⇒ Object

Records ONE violation and halts the finalize block immediately (the code after a violate! call never runs, so it can assume the checked invariant). The contract then fails as a normal 422.
