Independent Adversarial Probes

Codex created independent bad inputs beyond the supplied T1 replay. For in-process verifier probes, the actual result is the exact rejection code; the enclosing independent probe process exited 0 only after asserting every expected rejection. Invalid inputs emitted no certificate, PASS, official digest, or seal-like artifact. The packet's independent suite separately reported any PASS emitted: False | any seal/official digest emitted: False.

N6 duplicate and malformed-input table

Probe	Expected failure	Actual failure	Certificate / PASS / digest / seal-like output	Verdict
duplicate declared corpus member	N6_CORPUS_DUPLICATE	N6_CORPUS_DUPLICATE	NO	PASS
duplicate manifest member/path with different hashes	N6_MANIFEST_DUPLICATE	N6_MANIFEST_DUPLICATE	NO	PASS
duplicate exact HASH_MANIFEST line	N6_MANIFEST_DUPLICATE	N6_MANIFEST_DUPLICATE	NO	PASS
malformed one-space separator	N6_MANIFEST_MALFORMED_LINE	same	NO	PASS
uppercase/non-64-lowercase hash	N6_MANIFEST_BAD_HASH	same	NO	PASS
stale/tampered N6 certificate	verify false	false	NO new artifact	PASS

Packet completeness and authority probes

Probe	Expected	Actual	PASS/seal-like output	Verdict
remove authority_seal_encoder.py	reconstruction fails	RERUN.sh exit 1, manifest drift	NO	PASS
remove codex_probes.py	reconstruction fails	RERUN.sh exit 1, manifest drift	NO	PASS
reintroduce stale membership_sha256 (N1) text	conflict detector catches it	mutation detected; live rev4 remains clean	NO	PASS
attempt real N7 with empty authority provenance	SEAL_PROVENANCE_MISSING	SEAL_PROVENANCE_MISSING	NO N7	PASS

Existing suites rerun from fresh governed bytes

• Real-N6 verifier selftest: 19/19 PASS.
• Real-N6 adversarial suite: 31/31 fail-closed.
• Authority firewall: 8/8 rules hold.
• N-number checker: 15/15 PASS.
• Supplemental alignment probes: 10/10 fail-closed.
• T2 second-pass packet gates: G0..G6 PASS.

Authority firewall verdict

• Candidate class remains ENGINEERING_VERIFIED_CANDIDATE.
• Certificate states authority=NOT_A_SEAL and creates_n7_n8_p7=false.
• N6 ratification does not create N7.
• No N7/N8/P7 artifact was authored in this review.
• No hardcoded or disguised-hardcoded success path was observed in the reviewed rejection classes: mutated/duplicate/stale inputs fail before certificate/seal output.
