nx_estate_search_lib.nx

nx_estate_search_lib.nx -- THE ESTATE QUERY, as a library so a gate drives it in-process on a fixture shard (search rungs E1/E1b/E4, 2026-09-14). es_query ranks with dss_search (the SAME scorer the public search runs: one ruler, two corpora) and renders one line per hit into a caller buffer: rank TAB score TAB url (the url row, else doc:<cid>) TAB snippet (the first ES_SNIPPET bytes of the document with control bytes folded to spaces). It returns the hit count, or ES_UNREADABLE when the shard cannot be opened -- an absent shard and an empty one are different facts and only one of them is a defect. E1b DEFINITION PRECEDENCE: an underscored term is also asked as its definition token (ss_def_token, the token the tree ingest writes once per function head), and the hits are re-ordered by a TIER before the score -- a document carrying a typed term's definition token ranks above one that only mentions the term, whatever the BM25 magnitude (es_def_precedence, the shape of dss_exact_precedence: a lexicographic key needs no coefficient, and a discount constant here would be a magic number nobody could justify). A one-word function name has no definition tier -- a NAMED residual, the same condition ss_ident_collapse already draws. license_tier: ORIGINAL
