Reconcile every artifact that asserted the (since auto-reverted) mathematics_logic
expert promotion to the live machine state. Determinism proven intact (Week-1a):
the digest divergence is genuine single-source evidence-drift (GSM8K coverage probe
3/47 -> 4/46 via #310/#488), not a non-determinism defect. ADR-0120's fail-closed
property fired as designed; CORE revoked its own expert claim.
History keeps receipts; current-state reconciles to truth:
- Regenerate expert_claims_math_v1_signed.json -> promote_admitted:false,
reviewer_signature_matches:false, digest 02f6d3c8.
- reviewers.yaml math_expert_claims: quarantine note; entry kept (mismatch-refusal
keeps firing); intentionally NOT re-signed.
- ADR-0120-math-expert-ledger-flip: dated valid-at/auto-reverted header note.
- README: "next gate" narrative -> built-attempted-reverted; refresh stale count.
- docs/decisions/README: revert note + ADR-0200 index row.
- 3 fail-closed tests (2 files): "is-expert" -> fail-closed-revert assertions.
Were RED on main; now green (30 passed).
No eval gate, threshold, or safety boundary changed.
