{ "generated": "2026-09-16", "note": "Documents every ZIP-feature property key observed across all 1,233 features of data/atlas_data.json (D.zips), every county-keyed table named in W1-05's task spec, and every field on a D.systems[i] record (including the researched facts sub-object). Field order is positional unless a key's type is \"object\", in which case fields is a map of the object's own keys. Distances (\"mi\") are straight-line miles from the ZIP's population-weighted center unless stated otherwise; most nearest-facility keys follow the repeating shape [mi, name, city, countWithinRadius1, countWithinRadius2, countInsideZip, listInsideZip] with the exact radii varying by layer (see each key's fields). Two keys are reused with different meanings at the ZIP level vs the system level: zip 'pf' is the nearest post office, system 'pf' is PFAS occurrence; zip 'pl' is nearest gas pipeline, system 'pl' is Ohio EPA PFAS plant-sampling status. check_schema.py enforces that every key below is present and, for array props, that the documented field count matches the observed length(s). A table's \"confidence\": \"low\" means the whole table is never rendered (D-58); a \"field_confidence\" map marks single slots the same way (D-72), keyed as the readers name them: \"3\" for a positional slot, \"all[1]\" for an element inside an object-typed row, \"n[3]\" for that element of every row in a list-of-rows key. countytables.py refuses those slots and api.py omits them, from this one source.", "zip_props": { "z": { "topic": null, "name": "ZIP code", "type": "string", "source": "USPS ZCTA", "note": "the 5-digit ZIP/ZCTA code, same as the feature's own z property key used as the join key everywhere else." }, "n": { "topic": null, "name": "Place name(s)", "type": "string", "source": "USPS + local government join", "note": "up to 3 place names for the ZIP, comma-joined (USPS preferred city plus overlapping local-government names)." }, "k": { "topic": null, "name": "County (by residents)", "type": "string", "source": "Census block population join (scripts/join_zip_county.py)", "note": "the county most of the ZIP's residents live in, population-weighted (falls back to the county containing the ZIP's representative point when no populated-block data exists);
