 "reason": "proof.md revision 2 (after the skeptic review of revision 1). Fixed: both major gaps (PLUS-MERGE-1 now handled by a general merged-state lemma C3, a two-mode climb automaton C5 and both reflection branches C6; far-end 0+ rules FAR-0-PLUS-EVEN/ODD added and J3 relaxed) and all minor gaps (scaled budget f*2^u, SP smaller copy, 15 rules, (o1) wording, C1 statement, Reduction wording, (o5) count). Open, fatal: O1, no inductive invariant. J has five one-step exits and halting members (2 + 1 # 2 halts after 186 steps). New: the far end decides halting by a race whose outcome depends on history-dependent counter parities; 24 of 300 perturbations of line 75's 1e13 configuration leave the rule set between 1e14 and 1e85 steps, 22 of them at the far end (3 reach the halting + 0 +). The four real orbits meet no outside case to 1e100 (check_proof.py section I) and 1e150 (work/rev2/far.py). Cryptid-protocol stop; decision.json filed.",
