The curation base for a per-person gated `memory` collection of FREE-TEXT notes
(kind: note), distinct from ClaimsReviewQueue's subject·predicate·value triples.
Groups proposed (specialist-noted, awaiting confirmation) vs remembered (active),
with confirm/forget callbacks, source attribution, and tags — matching the KB UI
house style. Collection-agnostic (props in, callbacks out): the same base powers
the KB `memory` collection and a consumer's /memory page.
