GeoJSONFeature

A single GeoJSON Feature.

object
geometry
Any of:
GeoJSONGeometryCollection

A GeoJSON GeometryCollection (RFC 7946 §3.1.8).

fix(#430 codex r9): carries geometries instead of coordinates, so it needs its own model — only generic-GEOMETRY datasets accept it on write (enforced in the service), and any stored collection must serialize back out on read.

Deliberately NON-recursive (codex r13, refuted): PostGIS cannot round-trip nested collections through the GeoJSON boundary in either direction — ST_GeomFromGeoJSON rejects them on write and ST_AsGeoJSON raises ‘GeoJson: geometry not supported’ on read — so a recursive model could never receive one and would only convert the write-side 422 into a raw database 500. The write schemas add a raw-payload guard for a clear 422.
