the one envelope

Also: response envelope, shared envelope, API envelope

The one JSON shape every block.space ranking API answers with: as_of (the appendix, books and ranking heights), book, denom, family, sub, population, total, limit, offset, source and rows, with anything particular to one board under extra. It has been the boards' shape since 2026-10-19, so a reader learns one shape for all of them.

It is not the inscription envelope, the data carrier inside a taproot witness.
