Replace the outdoor root's single unified reverse-portal flood (whose root-level portal-side test oscillated as the chase eye grazed a doorway — the measured flood 2<->6) with retail's per-building floods. - OutdoorCellNode.Build(uint): portal-less land root; floods only itself -> full-screen OutsideView -> terrain (PortalVisibilityBuilder IsOutdoorNode seed). - PortalVisibilityBuilder.ConstructViewBuilding: per-building flood seeded at a building's own finite entrance (retail ConstructView(CBldPortal) 0x5a59a0 via DrawPortal 0x5a5ab0 / portal_draw_portals_only 0x53d870). Entrance-bounded -> consistent ~2-cell depth (measured retail cell_draw_num, handoff OPTION-A 3.4). - RetailPViewRenderer.DrawInside: when the root is the outdoor node, group nearby cells by BuildingId and merge each per-building flood into the frame before assembly; existing shells/object-list draw path unchanged. 48 m seed cutoff. - GameWindow: pass flat NearbyBuildingCells only on outdoor-node frames. Tests: +3 PortalVisibilityRobustnessTests (per-building touches ~2 cells, membership stable under the measured 36 um eye jitter). UnifiedFloodTests retired (its subject, the unified flood from the outdoor node, is removed); surviving full-screen-OutsideView coverage moved to OutdoorCellNodeTests. App Rendering 207/207, Core movement 14/14. Conformance-verified sound; the grazing-doorway flap is the visual acceptance test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
