/**
* resolve — which reads a PROSE claim names (design § 5.2): by the entity each call was SENT
* for (its `resolved` id, name and aliases — store data never binds another entity's name), or,
* for a search with no population, by its `source.said` words.
*
* Pattern: mentions are token runs of the unit that hold a name by the library's one name rule
* (`lib/normalize.ts` · `sameName`: `Payments` is `payments`, `ARRAY-X9` is not
* `array-x9`); a mention joined to another word by "or",
* "and", "nor" or a comma is a second entity, and an entity no read resolves makes the
* whole claim `entity-unresolved` — "payments or checkout" with one searched cannot pass
* as checked. The reads a claim RESTS ON are this turn's reads (any leg) of a resolved
* entity whose tool's `subject.said` word the unit names; a call on the same entity and
* another subject is never pulled in. A claim naming no entity is unresolved; the
* person's message and the single call of the turn only name a CANDIDATE.
* Role: integrity/ layer (L3), read by `prose.ts`.
