about

nx_geo_places.nx -- LIB: GEO-021 PLACES-SEARCH (fuzzy / typo-tolerant place lookup) via sovereign Levenshtein edit distance. GEO-006 geocode does EXACT name match; this adds fuzzy ranking so "Tokio" or "Chcago" still resolve. Rides the SAME gazetteer (here a NUL-separated name list; the GEO-006 store gazetteer can be flattened into one). THE EXCEED ANGLE: deterministic integer edit-distance ranking -- the best match and its score are reproducible to the bit (no float similarity heuristic / nondeterministic tie-break). Sovereign, no search API, no data hostage. The name list is "name1\0name2\0...\0\0" (double-NUL terminated). license_tier: ORIGINAL
