test(pre-push-safety-net): record the M1b production comparison on NodeGoat

Rerunning the three pinned revisions after tasks 10.1-10.6 shows the production
comparison classifying all of them with no lifting, and agreeing exactly with the
recorded view. That agreement is the point: the vetoes M1a recorded were repaired
rather than bypassed.

The vulnerable revision is new with operation_absent_from_comparable_base, and the
three eval witnesses at contributions.js lines 32 to 34 are attributed to the
change that introduced them. The fixed twin is analyzed and quiet with three
base-only findings. The unchanged revision is unchanged. In M1a every one of the
436 questions was demoted on both sides and production reported
witness_identity_unresolved on every finding.

All three artifacts still report finding_status none with zero admitted defects.
Admission rejects on capability_unavailable, the deliberate eligibility gate, and
on dependency_unresolved, which the rerun exposed as coarse plumbing: the runner
passes every coverage reason as every candidate's dependency gaps. That is now
task 10.7, ahead of M4, since it would block admission forever once capabilities
qualify. It is not a comparison failure and not an M1b exit blocker.

Three comparisons on one inspected teaching repository under a development budget.
No capability enabled, no alert emitted, no latency claim. Runtime, independent
qualification and rollout all remain NO-GO.
