Pin the resolution reached in the grill: planning status persists as a
per-UPRN write-through cache in the existing `property_details_spatial` table
(not FE-property columns), read back off the Property in Modelling; unknown
UPRN defaults to unrestricted, matching legacy `empty_spatial_df` (superseding
the earlier "conservative stance" note).

Captures the grill-with-docs session for solid-wall insulation: CONTEXT.md
gains EWI/IWI Measure Types + the Wall Insulation Eligibility rule (+ a
flagged-ambiguity that the three planning flags stay distinct, never recollapsed
to legacy restricted_measures). ADR-0019 records the eligibility policy (cavity
-> cavity only; brick/system -> IWI+EWI; timber -> IWI only; cob/stone -> none;
conservation/flat block EWI, listed/heritage block both). ADR-0020 records
conservation/listed/heritage as three distinct Property attributes sourced by
extending the geospatial S3 repo (flags co-located with lat/long).
