/**
* containment — the prose door's notes (design § 5.2, § 5.3): what a typed citation would have
* made exact, said about a prose claim against the reads it rests on. A note never withholds.
*
* Pattern: the reads of one entity are grouped by search (`readings.ts · readingKey`) and each
* search's reads merged. Each search gets its OWN notes: how it read (`call-not-read`,
* `empty-undeclared`, `clarify-open`, the rows rule), its row (`coverage-unverified`,
* `declaration-overclaimed`), its gaps by facet (`coverage-gap`, `cap-reached`, `paged`,
* `partial`, `gap-relevance-unknown`), its period (`period-*` where the unheld time
* overlaps the claim's window), containment (`scope-wider`: a fixed qualifier or a
* filter in effect the claim does not name through the declared words, no window over
* a search with one, a window wider than the one read, an unbounded word), and the
* sequence (`later-read-failed`, `superseded-by-write`).
*
* A search with no note ESTABLISHES the claim; the claim is then noted only by what the
* other searches BEAR — rows that contradict it, reads that disagree, unheld time over
* its window. With no establishing search, every search's notes stand. So an extra
* read clears no other read's objection.
* Role: integrity/ layer (L3), read by `prose.ts`.
*
* Words decide only through declared `said` lists; a hedge never scopes; a host-filled identity
* filter is the caller's own view and is never asked of a prose claim.
