The per-building join diagnostic PASSES (001a/0022 portal tables lead
exactly to the traced a9b4016x punch cells; every BSP PortalRef indexes
validly), and the eight-arm gate-decode sweep proves NO plane-sign x
side-flag combination reproduces retail. Together they pin the missing
mechanism: CEnvCell::GetVisible gates punches by the LOADED interior
cell set around the player - retail punched only the two buildings
nearest the player cell; the replay loads every interior so geometry
alone over-punches. Next port piece: the interior load radius (the
landcell stab-list pull). Both diagnostics stay in the suite (the sweep
Skip-parked with the verdict).
