about

nx_canon_bin_gate.nx -- prove the binary-safe canonical primitive (the gap in the substrate). Asserts: BINARY-SAFE : a value containing 0x00 bytes round-trips at FULL length (string-only canon_encode truncates it). CANONICAL : the same fields in DIFFERENT insertion order encode to BYTE-IDENTICAL output (=> identical CID). CID : cid_of (the REUSED substrate sha256 CID) is well-formed + deterministic. DECODE : canon_decode_bin recovers every field; the binary value (via offset+len, IN-buffer) matches. GREEN = the substrate now has a binary-safe canonical record (additive sibling; media can be a first-class value). expect_exit: 0 license_tier: ORIGINAL
