Reconciliation first: the two round-13 reviews CONTRADICT on FORK. Opus (flagged mid-review as flipped, per operator): 'frame-resistance unsound as stated' because payloads carry timestamps. GPT: 'the right EUF-CMA form.' Independent re-derivation sides with GPT: a winning head needs a VALID SIGNATURE on its never-queried exact payload bytes — a forgery regardless of timestamp; Opus's no-forgery scenario never produces the valid signature it presupposes, and its own fix paragraph concedes the win condition already means exact-payload freshness. Its real residue (the (n,r)-injectivity parenthetical was a red herring in that proof) is adopted: the parenthetical is gone, injectivity is now its own lemma where it belongs. GPT findings, all verified then fixed: - Theorem 5 formal error (CONFIRMED): the proof applied transport to same-size transitions outside the lemma's n0<n1 hypothesis, and the lemma's last line smuggled that case. Lemma restated for n0<=n1 with the equal case explicit; HIST proof now case-splits (equal: Ext forces equal roots, opening carries over; growth: transport). - Prefix transport (CONFIRMED under-proved; Opus concurs): the frontier narrative is replaced by a FULL induction over the ConsRec recursion, with the verifier recursions displayed, the value-equality invariant (rho = y) threaded exactly as the corpus's extractConsNode analysis identified, explicit P0 assembly per branch, the no-mismatched- stopping-points argument (shapes are integer-determined), and the power-of-two split-stability step credited to the corpus's mechanized kbelow lemma. - FORK cross-log framing flaw (CONFIRMED): evidence predicate now context-scoped — fixed chi = (log id, schema/type, hash-alg, pk) declared once, encoded in every head; one key running two logs can no longer be classified as equivocating. Prose corrected to 'issued-message attribution' (no more 'never equivocated' oracle mismatch). - HEAD-AUTH game added (CONFIRMED gap): outsider forging one ordinary head reduces to EUF-CMA; G1's forgery leg is now discharged by an actual game, closing the network-attacker hole. - Two-level formalization (CONFIRMED): Definition 3 = collision- extractable accountability (unconditional, explicit reductions with stated costs); NEW security corollary = what human-ignorance CR + EUF-CMA + correct key + fixed context then rule out. Extractability no longer masquerades as hardness. - Composition mapping made precise: G1 narrowed to authentic position binding (HEAD + PB opening-uniqueness; full-list membership is a system property of the published mirror, said so); G2 split into syntactic pin rule vs semantic HIST content; monotone-extensions and payload-injectivity as one-line lemmas; HIST game syntax lists C_i and 0<=a<b<=k; Adv defined for the two keyed games; PB cost notes retained intermediates; Rogaway bibitem gains the DOI (211-228 reconfirmed by GPT: Springer/DBLP vs the author's list-page typo). 21 pages, 0 overfull, suite 115 green.
