deny-receipt.hex was pinned to the superseded jcp/1 receipt profile (598 bytes) while the reference gate seals jcp/2, which binds a payload_hash (677 bytes). The gate is deterministic (three runs byte-identical) and the new envelope decodes to every field receipt.json records, so this is a refresh, not a behaviour change. The conformance test now seals the deny exactly as the README reproduces it and requires the published bytes on every run, verifies them under the reference steward against receipt.json, and requires any other key to fail. Falsified: the old receipt back in the pack fails the byte check; a changed deny_reason in receipt.json fails the decode check. Co-Authored-By: Claude Opus 5.5 <[email protected]>

"description": "A sealed JCR-1 gate decision receipt (SPEC §5) for the ungranted 'Bash' action against the granted set [Read, Grep, Edit] — the deny that the gate sealed. The raw COSE_Sign1 envelope is in `deny-receipt.hex` (677 bytes, byte-deterministic under the reference gate's fixed dev keys; payload profile `jcp/2`). Decoding + verifying it under the steward key MUST yield the fields below.",
