cad_parcels.geom is geometry(Polygon, 4326) — strict schema. NSPD
occasionally returns Point geometry for parcels without detailed
boundary, causing INSERT failure:
psycopg.errors.InvalidParameterValue:
Geometry type (Point) does not match column type (Polygon)
This killed pilot v8 at quarter 66:41:0104002 — worker autoretry
exhausted, job hung at 25/50 (heartbeat stale).
Fix: filter geometry.type at Python level in upsert_parcel + upsert_zouit
(same pattern as upsert_quarter_geom_from_feature). Non-Polygon
geometry → geom=NULL, raw_props preserved.
Tables with permissive GEOMETRY schema (cad_buildings, cad_constructions,
cad_enk, cad_oncs) unaffected — they accept any geometry type.
Tests: 3 new (Point parcel → geom=NULL, Polygon happy path, LineString zouit).
