Scope

Repair MAT009-AUDIT-001 in the standalone Lean declaration and axiom gate for the frozen MAT-SPEC-009 source (production commit 0758a96360726aafbb07abed34620eda178407ae). No production or historical release files change.

Repair and evidence

• Preserve the original independent FAIL at formal/sonification/mat009/audit/report.json and replay its exact _cstage1 False axiom bypass.
• Check every project declaration's axiom closure, including compiler auxiliaries. Permit only propext, Quot.sound, and Classical.choice for safe declarations. Disclose and tightly check the two recorded unsafe compiler axioms and compiler mechanisms.
• Retain a fresh Lean 4.19.0 receipt: 351 declarations, 22 named intended theorems, 1,303 hashed imports; named theorem types and axiom reports match the prior receipt.
• Add the exact bypass as a permanent negative control. All seven controls pass.
• Fresh independent audit of frozen candidate b07942c77bebb15c99d8a70f52397d4077694ea0: PASS for the repaired scoped mathematical audit gate, including an independent _cstage2 adversarial variation. Report: formal/sonification/mat009/audit/repair-audit-001/report.json.
• Focused receipt tests: 15 passed. Ruff: pass. Frozen source binder and retained source receipts: pass. The earlier full repository result (329 tests, 202 subtests) remains retained, not restated as a post-repair run.
• Record scoped results in the theorem map and install pinned Lean in CI for the receipt tests.

Boundaries

REFINEMENT_PROVED remains OPEN for MAT-009 and the direct MAT-008 parent. The general MAT009.partition target remains OPEN. These model proofs and finite cases do not authenticate physical evidence, independence, or classifier accuracy. MAT-SPEC-010 stays deferred.
