build_prediction_target assembles an EPC-less Property's PredictionTarget from its identity (postcode), resolved coordinates, and Landlord-Override attributes (property_type / built_form / wall_construction). The eligibility GATE: a Property whose property_type is unknown returns None — never sized from a mixed-type cohort (ADR-0031). property_type is the hard cohort filter. The override attributes are read through a PredictionTargetAttributesReader port (stub seam) — the real adapter (a read over property_overrides) is being built separately by the team; ingestion wiring depends on the abstraction and tests substitute a fake. 2 tests (assembly + gate); pyright strict clean.
