The mutation replaced 'return value * 2' with \"raise TypeError('control broke runtime')\", a runtime-breaking control rather than a behavioral mutant; the recorded output_tail is a TypeError traceback out of src/engine.py line 2, which any test that merely calls double() would produce. That demonstrates test reachability, not that the test discriminates the doubling behavior, so the claimed behavioral kill is not established by the executed results. The implementation itself is not refuted: restored and baseline runs are both green (exit_status 0, tests_run 1, OK) and restored_source_sha256 equals source_sha256 e77335c804a116a2e8a7445a96ea133bd60d7bbe5361606d933bcb5509392962, so src/engine.py and tests/test_engine.py need no correction.

Per the delivered rule that missing required proof returns its obligation to repair regardless of verdict or severity, repair precedes review; acceptance-context reviews is empty, so no independent judgment is retained or applicable (retained_review_ids empty), and the three review blockers cannot be addressed against a proof that is invalid on its face.

(1) Finding identity: adversarial review 916d2c2f (receipt arb-step-review-43c919bc7a6b423fb46c5134852fd03d) opened F-required-oracle against REQ-0.1.0-01-01 with verdict 'refuted'. That is a historical refutation, not a live blocker. (2) Repair is real in the tree, not asserted: tests/test_engine.py:10 asserts self.assertEqual(double(2), 4) -- a literal expectation for the obligation's stated 'Double two to four.', independent of the production oracle in src/engine.py ('return value * 2'), which is exactly what F-required-oracle demanded. (3) Independent closure is current: spec d0088755, quality 24ae32fd, and adversarial c844b505 each record closures[0] = {finding_id: F-required-oracle, obligation_id: REQ-0.1.0-01-01, proof_id: proof-87cbe809f8054237b0eeca894db1b626}; the latest adversarial review c844b505 returns verdict 'accepted' and explicitly lists proof-87cbe809f8054237b0eeca894db1b626 in accepted_proof_ids. Reviewer_id 'independent-session' is distinct from contract author_id 'synthetic-seed-implementer'; tier 1 with empty fallback_reason, so no degraded-tier caveat applies. (4) Proof output read in full and discriminated from error: the mutation witness 'triples instead of doubles' (find 'return value * 2' -> replace 'return value * 3') yields outcome 'killed' with failure_class 'assertion' and output_tail 'AssertionError: 6 != 4' at tests/test_engine.py line 10, with compiles=true, imports=true, target_present=true, source_changed=true. The mutant was caught by a behavioral assertion, not by an import/collection failure, so the proof is not hollow. Restored run is exit_status 0 / green=true, restored_source_sha256 e77335c8 equals pre-mutation source_sha256 e77335c8, and input_before equals input_after equals 07585433, so no mutation leaked into the recorded input snapshot. (5) The most recent ledger event, proof-de9fd41fc1e9458d983ec006f0710126, is a repeated successful execution carrying claim_digest v1:217b29cb73a26021a62673123e60ac260f252f0a0562fce581658d93e64d99fd, input_digest 07585433, contract_digest 349c9df8 and conditions_digest 44136fa3 -- all identical to proof-87cbe809; the recorded evidence differs only in the ephemeral pycache_prefix temp path. It reproduces the already-reviewed claim rather than superseding it, and it does not invalidate proof-87cbe809, which remains present, valid=true, and bound to the current input_digest. The closure link therefore still points at a current proof. (6) No newly established required gap exists, so no review.json was manufactured; the existing F-required-oracle identity is preserved and already closed. Runtime derivation agrees: ready=true, blockers=[], open_findings=[].

The adversarial stage supplies approval as well as closure: accepted_proof_ids = [proof-87cbe809f8054237b0eeca894db1b626]. (2) The repair is observable in the subject, not asserted by wording: tests/test_engine.py:10 is self.assertEqual(double(2), 4) - a literal expectation matching the obligation statement, not derived from the production oracle - against src/engine.py:2 'return value * 2'. (3) The proof output is an assertion outcome, not a harness error: the mutation witness 'triples instead of doubles' (return value * 2 -> return value * 3) reports compiles=true, imports=true, target_present=true, source_changed=true, failure_class='assertion', exit_status=1, outcome='killed', with output_tail 'AssertionError: 6 != 4'; restored.green=true, restored.exit_status=0, tests_run=1, and restored_source_sha256 == source_sha256 == e77335c804a116a2e8a7445a96ea133bd60d7bbe5361606d933bcb5509392962. The selector tests.test_engine.EngineTests.test_double appears in executed_tests for baseline, witness, and restored runs, so the test genuinely discriminates. (4) The retained reviews remain applicable to current state: their input_digest 07585433c131c1920d0d7b913f02b6e651eec25bf9f28a43848181d6bfd70f69 equals the current acceptance input_digest, the proof they close against is still present with valid=true, and each carries recorded_current_ids = [proof-87cbe809f8054237b0eeca894db1b626]. (5) The newest event, proof-de9fd41fc1e9458d983ec006f0710126, is an equivalent successful re-execution, not a changed claim: it shares claim_digest v1:217b29cb73a26021a62673123e60ac260f252f0a0562fce581658d93e64d99fd, contract_digest 349c9df8..., input_digest 07585433..., conditions_digest 44136fa3..., selectors, source sha, and mutation set with the reviewed proof; only the record UUID and the pycache temp prefix differ. Per the delivered rule that an equivalent successful execution does not by itself invalidate review and that the acceptance consumer decides applicability, this introduces no unmet obligation and no counterexample - the consumer view reports ready=true, blockers=[], open_findings=[]. Redispatching review solely because a duplicate green run carries a distinct UUID would be manufacturing a round after independent closure is established. No unresolved in-scope finding, no missing required proof, and no scope-boundary disclosure remains outstanding; the correct next action is to present Step 4a evidence together with the retained independent review set and solicit operator attestation.

This caveat names a naming preference. The commentary is retained as a disclosed style observation, not silently promoted to an acceptance prerequisite, and it is not dismissed for being auxiliary -- it is dismissed on relevance.

The dispatch obligation is satisfied; what is unmet is repair. Required next: give REQ-0.1.0-01-01 an expectation independent of the production oracle (assert the literal 4 rather than expected(2)) so the tripling witness is killed, re-execute proof for the repaired obligation, and import explicit independent closure linking F-required-oracle to the new proof id.
