Review follow-ups of PR #415. The container does have python3 (pulled by
the apt packages of the install step, run 517): awk is kept because mawk
is part of the ubuntu:22.04 base image, which the workflow comment and
the ADR now say. #344 is a PR and the second drift, not the third. The
awk exit-code test is described by what it alone catches (an awk that
fails after printing every fact). The repair procedure gains the two
failures it had no answer for, and the ADR names the canary's limit.
The release commit edits Cargo.lock on main without a PR, so /release
now replays the guard's exact step text right after that edit (step 2),
checked on the stack's lock (exit 0) and on a drifted edge (exit 1).
