The user's primary symptom (interior walls + cellar floor render as grey clear-color
with dynamic objects / outdoor slices showing through; flicker at room/cellar
transitions) is the KNOWN R1-completion problem: the PView flood roots at the CAMERA
cell (viewer cell), and when the camera is in a different interior cell than the player
(room 0171 vs cellar 0174), the flood does not seal the player's cell. Decisive
evidence: flap-cam root=0xA9B40171 playerCell=0xA9B40174. This handoff separates the
two problems I conflated, lists the disproven causes, gives the next diagnostic step
(shell/flap/vis probes in the cellar), and a kickoff prompt. HEAD 2b7f5a1.
