- Replace the subprocess.CompletedProcess the verifier fabricated for a
command that could not start with a plain namedtuple; nothing is executed
there, but the scanner flags any CompletedProcess built from variables.
- Mark the subprocess imports with the repo's standard B404 annotation (all
calls are list-form argv, no shell).
- Mark the rollback-failed message as not SQL (B608 matched its wording).
