re0-order

1Move the items of a named listing into one order a reader can name, changing nothing but their positions.

3## Goal
4 
5A listing carries meaning when related items sit together along one clear axis; items appended where they happened to be written blur that. `re0-order` realigns the set under one principle a reader can name, moving items and changing nothing else. It acts on a list, table, catalog, set of sections, or enum the human named, or one inside a scope they named or a pipeline they invoked passes on. The result lands in place: in the listing itself and in every copy that mirrors it.

7## Workflow
8 
91. Pin the listing and its items: the ordered set in focus, inside the scope the human gave.
102. Name the one principle that makes the order most meaningful, from workflow or lifecycle sequence, dependency, grouping by kind, severity, frequency, alphabetical. If a latent order already exists, surface it and complete it instead of imposing a new one. When it is unclear whether the current order is deliberate, surface that call to the human and let them decide; move nothing until they do.
113. Put kin next to each other, then sequence those clusters by that one principle.
