Provenance

Sealed job 8e5eb20b089e7aaeb140fc2cfffee50b. Shards: scholar.openalex, encyclopedia.wikipedia. Dropped 2 off-topic collector hit(s) and 0 off-topic local claim(s). Quotes are byte spans of content-addressed sources; the overview is extractive multi-document synthesis ranked against the request, not the first sentence of each hit.

Each asks for new research: a few cents, shown first.

For agents: the quotes as data, GET /wiki/ndjson with Accept: application/json; free within the daily allowance, else a small price that is a share of the fetching and reading it replaces.
