WalkPView transcribes ConstructView @0x005a57b0, InitCell @0x005a4b70,
InsCellTodoList @0x005a4f50 (nearest-first pop), ClipPortals @0x005a5520,
OtherPortalClip @0x005a5400 (inverted ==0 sidedness), AddViewToPortals
@0x005a52d0 (update_count watermark, duplicate-reach arm), AddToCell
@0x005a4d90, SetOtherSeen @0x005a4e30, FixCellList/AdjustCellPlace/
AdjustDrawList/AdjustCellView @0x005a5250/0x005a5010/0x005a4e90/
0x005a5770, plus set_view and PView::GetClip @0x005a4320 over the
WalkScreenClip chain. Resolves and documents the portal-flag convention
(inflag=1 = the portal FACES the viewer and feeds max_indist; inflag=0 +
armed seen = an opening — the same side condition building look-ins
require), which the PDB names obscure. WalkWorld supplies the cell model
and frame-context seam. Six synthetic-world flood tests pass on first
run: traversal, facing rejection with the exact distance key, exit-view
raising, entry-portal no-ping-pong, chain ordering, unloaded skips.
