Mutation testing for Ruby and Rails. Uses Prism-based source-span mutations (no unparser), coverage-mapped test selection, and a fork-per-mutant kill pipeline. Scopes to changed methods for a fast dev loop, or to a diff for CI. Includes an incremental coverage baseline and a committed acceptance ledger for equivalent mutants.
