Verify and stop

Translate acceptance conditions into smallest sufficient proof set.

Reuse still-current results with matching repository state.
Run focused checks before wider gates.
Distinguish pass, fail, unavailable, and blocked exactly.
Do not edit product code unless verification request includes fixes.
Do not add polish, cleanup, or unrelated tests after criteria pass.

Stop immediately when acceptance proof is complete. Report commands, results, and unresolved risk only.
