# CAIN-A75-011 Formal Artifact Review

**Verdict:** VERIFIED

> Audits a formal-artifact record: artifact/checker/statement binding, checker results, dependency certification, placeholders and axioms, and claim honesty. It does not run the checker or re-prove the theorem.

## What this proves and what it does not
- Proves: the artifact record is bound to one statement and one checker, every result says pass, dependencies are certified, no placeholder remains, and only allowed axioms are used.
- Does not prove: that the checker is sound, that the record is truthful, or that the theorem is the one a buyer cares about. Running the checker is a separate operation.
