about

nx_fin_research_fetch.nx -- the Nishi RESEARCHER's sovereign web-fetch for THE NISHI FINANCIAL ECOSYSTEM arc. Mirrors the proven nx_pub_research_fetch / nx_research_fetch pattern: own TLS-1.3 (nx_https_fetch_follow) + Mozilla CA store, saves each cited source to knowledge/fetched/fin_*.raw so research COMPOUNDS to the Library and can be grepped to CITE. 100% sovereign (own TLS, nx_cc->nxasm, no curl/wget/gcc). Idempotent have-skip = re-run fills gaps (also the per-fetch mmap-leak workaround -- run multiple passes; each pass is a fresh process so memory resets, NO wsl --shutdown needed while sibling workstreams are live). COVERAGE: the FIN-R financial-ecosystem topics (crisis + stabilize + engine + markets + asset classes + learning/tax/compliance/macro) PLUS the markets-investing expansion (2026-06-24, operator: "full finance for trading ... interacting with markets ... projections ... understanding the people who run companies, good or bad, like betting people evaluate a team ...
