Execution-Grounded Review

A normal review reads the diff and asks "does this look right?" — and an implementation can look complete while a criterion silently fails. This skill refuses to grade an implementation on appearance: it runs the suite first, then traces each acceptance criterion to execution evidence — a test that actually exercised it, or observed behaviour — and marks anything it cannot back with execution as UNVERIFIED rather than passing it on faith.

It is the execution-grounded verifier in the agent-patterns review family: where adversarial-review attacks a design for faults and cold-read-gate measures whether text survives a reader, this skill verifies that running code meets its stated acceptance criteria. It is the reusable independent verifier a judgement-based loop gate delegates to (.claude/rules/loop-integrity.md, Pillar 1).
