feat(pre-push-safety-net): record admission vetoes and meet M1a on NodeGoat

Add group 9 to the approved task plan as the bounded owner amendment release
milestone M1a requires, implement the task-local recorded-veto evaluation flag,
and run the three pinned NodeGoat revisions under it.

The flag re-runs the production comparison and admission over a lifted copy of
the same evidence and records each veto instead of applying it. Recognized
completeness vetoes are lifted and logged; failures never are, because silence
from a failure is not a quiet fixed twin. It is off by default, accepted only on
explicit base/head replay, refused in Git stdin mode, labels every payload it
produces, and admits no defect even when a lifted candidate otherwise would.

M1a outcome, inside its one-week box and with expectations frozen on disk first:
the three entailed <lambda>2 witnesses are present at contributions.js 32-34; the
fixed twin was genuinely analyzed and quiet, answering its target question with
zero rows and no deadline reason while the same findings appear as base-only; the
unchanged revision was analyzed and recorded unchanged. The kill criterion did
not trigger.

Five vetoes fired and were recorded. M1a also corrected the diagnosis: with all
five lifted the detection still stops at operation_correspondence_unresolved,
because a newly introduced operation sits on a changed line and has no base
anchor. The unchanged revision resolves its base location on the same lines and
classifies as unchanged, which isolates correspondence as the mechanism. That
fifth veto was not in the earlier four-veto diagnosis and is now M1b's central
repair.

Diagnosis only. No defect admitted, no capability enabled, no gate changed, no
latency claim; the 900-second development budget cannot measure the hook gate.
Rollout and task 8.3 remain NO-GO.

### Immediate next action
Add a task-local recorded-veto experimental flag and run the pinned NodeGoat
vulnerable, fixed and unchanged revisions under it (M1a). The raw `<lambda>2` witness
already exists; the deliverable is that witness plus the exact list of admission vetoes
that discard it. Then repair only those vetoes and rerun through production rules (M1b).
Normal hook eligibility stays disabled during this experiment.
Repair the five vetoes M1a recorded, then rerun the same three NodeGoat revisions without
the flag through the production rules (M1b). Start with operation correspondence for an
operation on a changed line: M1a measured that this one survives every other repair, and it
was not in the earlier four-veto diagnosis. The others are per-family change context,
question-owned vendor relevance, file-wide correspondence ambiguity scope and
query-to-operation provenance. Vetoes that did not fire stay unchanged and their families
stay experimental. Normal hook eligibility stays disabled.
Do not start another broad speed campaign before this outcome exists. See the
[M1a evidence](../specs/pre-push-safety-net/m1a-recorded-vetoes.md) and the
[owner diagnosis](../specs/contributor-scan/release-remediation-research.md).

[the milestone spec](../specs/pre-push-safety-net/release-milestones.md). M1a is met
(2026-09-16: witness shown, fixed twin analyzed and quiet, five vetoes recorded); we are at
M1b, repairing only what fired. M1a added a fifth veto the earlier diagnosis missed:
operation correspondence for an operation on a changed line.
Task counts and an experimental alpha tag do not establish release readiness. PMPro
remains a core regression/development case; any PMPro core retune still requires frozen
Node transfer evidence. This sequence supersedes older runtime-first next-step wording.
