Completes the GenerateSkeleton dispatch T-1022 wired (which only carried
founding_orientation). build_skeleton_work_item now also threads:
T-1039:
- political_archetype — real value from CityPlacement, replacing the Commission stub.
- morphology_zone — looked up from the covering DistrictProfile via new
scale::heightmap_pixel_to_district (exported HEIGHTMAP_CELLS_PER_DISTRICT;
cascade.rs drops its local CELLS_PER_REGION literal for the shared const).
- arrangement_pattern — RE-DERIVED at L4 (option b) via the single pure fn
attractor_matching::arrangement_pattern(&archetype, &economic_role); both
inputs already at L4. No CityGenerationContext field, no stored derived state
(DB-as-cache). Parity test asserts L4 re-derivation == L3-stored value.
T-1043:
- road_entry_directions — derived from T-1038's BodyWorldState.road_graph:
octant = bearing of each incident road edge, deduped per octant, ordered by
MaintenanceAuthority rank (the AdminFacing prestige-edge consumer). Feeds
derive_access_points -> AccessKind::QuarterEdge; BlockJunction fallback now
fires only for genuinely isolated settlements.
Acceptance covered: Corporate+Fjord -> Ribbon topology (not mesh+Commission);
settlement with a road -> QuarterEdge on the correct octant. 11 new tests.
