The answer is a member, not the document

Spec 053's `## Verification` block compares the whole of `registry plan --next --json` against one spec object, and spec 074 moved that object under a `next` member so the empty ready set could be a value rather than a missing document, so `spec-spine verify 060` has been red since 093 merged. 093 declared an `amends` edge to 060 for exactly this change and carried the replacement text for 053's rule; what it could not reach was 053's acceptance, because spec 037 forbids editing the amended file and the block lives inside it. The same block leaves 053 3.2's strongest requirement unasserted: that `--next` is a projection of `plan` and does not reimplement selection, which a one-element fixture cannot show. This spec declares 053's acceptance replaced and carries the corrected block, without editing 053's file. It is the third of the four follow-ons spec 084 4 named.
