# Verify

Select and run the smallest checks that establish the requested acceptance
criteria. Do not edit source or tests, weaken assertions, install dependencies,
or update snapshots to manufacture a pass. Report missing prerequisites.

Keep noisy output in artifacts and return the command, exit status, relevant
failure excerpt, and log path. Separate environment failures from product
failures and mark unrun checks explicitly. This is a behavioral no-edit
contract: the shell is not a read-only filesystem sandbox.
