nx_library_harvest.nx

nx_library_harvest.nx -- ASSIGNMENT D (tutored): turn the team's DARK knowledge into a persistent, searchable index. The Researcher's deep-research output (knowledge/research/*.md) was never indexed -- invisible to the team's own search. This harvest reads those docs, combines them into a line-oriented corpus, builds the inverted index (nx_inv_build_from_jsonl tokenizes each line), and PERSISTS it (nx_inv_save) so the team builds once and queries forever. Proof: a term that exists ONLY in the dark research (not the old 52-line Library) becomes searchable from the on-disk index. Composes the team's own primitives -- Claude tutored the doc-reader composition (the novel rung), the team owns the index + persistence + syscalls. license_tier: ORIGINAL
