audit-milestone's Nyquist scan classified a phase from `nyquist_compliant`
alone, so a phase seeded by plan-phase but never run through validate-phase
read PARTIAL — identical to a phase that validated and genuinely failed. The
template's `status` field could discriminate the two, but no workflow ever
promoted it off `draft`, so it was dead.
Make `status` live and read it:
- validate-phase.md §6: set `status: validated` in both the create (State B)
and update (State A) VALIDATION.md paths.
- audit-milestone.md §5.5: parse `status`; add a distinct NOT-VALIDATED bucket
keyed on `status: draft`, gate COMPLIANT/PARTIAL on `status: validated`, and
report `not_validated_phases` in the audit YAML.
- VALIDATION.md template: document the draft → validated lifecycle.
Tests & generated artifacts:
- Regression test folded into policy-138 (owning workflow-contract file);
fail-first verified vs origin/next (0 matches pre-fix).
- Regenerate golden-install-parity fixtures cleanly: adds the previously-missed
qwen.json and removes a contaminated `settings.local.json` entry that had
leaked into claude-local.json (the harness excludes hook-config files).
- Correct a stale validate-phase.md workflow-size-baseline entry.
Closes#2117
