When two requirements clash, for example "refund every eligible order" vs "orders on fraud hold go to manual review", an AI coding agent has to guess which rule wins. muse-guard makes that decision explicit and checks the code follows it.

How it works:
1. Muse Spark turns plain-English requirements into a rules table. Every rule quotes its exact source sentence, and the developer confirms each one.
2. An exhaustive search over the declared inputs finds every conflicting action before any code is written, with a preview of what changes under each choice.
3. The developer picks which rule wins, creating an approved v2 of the rules.
4. Muse Code implements the decision, and an independent sandboxed checker verifies it with visible and hidden tests the agent never sees.
5. Every run produces a downloadable evidence record.

Results: in a real run, Muse Code updated a small returns service after my decision and passed 4/4 policy cases and 7/7 existing regressions. A pre-registered study of 160 runs found no contradicted "done" claims and no test edits by Muse Code; we report plainly that muse-guard did not make it more honest. Its value is the explicit decision and the checked result.
