D-229 makes BuildingPropertyTag the typed step-3 output that replaces the era/
society_profile/zone_palette String stubs on the skeleton. The tag + its derivation
(zone_type_id, flavor_ref, era/ConstructionEra, FloorExtent) all landed under T-957/
T-1006; this removes the now-dead stub fields they superseded:
- BlockSkeleton.era_modifications: Vec<EraModification> (era is per-footprint on
BuildingPropertyTag.era now; era_cause retained as the block-level cause)
- QuarterSkeleton.society_profile: SocietyProfileRef (culture → tag.flavor_ref)
- QuarterSkeleton.zone_palette: Vec<ZoneDefinition> (zoning → tag.zone_type_id;
distinct from FloorZone.zone_palette: ZonePalette, the real D-101 palette, kept)
- the now-orphaned `EraModification` and `SocietyProfileRef` String aliases
Kept: chunk_layout (real ChunkLayout / D-234 street network), z_band_zones (still
uses the ZoneDefinition alias), boundaries (separate stub, not D-229 scope).
cargo check + clippy -D warnings --all-targets clean; full server lib suite
