Long session that shipped A6.P4 infrastructure (Tasks 1-6 of the
per-part BSP plan) but discovered the specific shapes we register
from door setup 0x020019FF don't catch the player. Per-part BSP at
0x010044B5 produced ZERO collision attributions in 188K+ resolve
lines despite player walking at doors. Cylinder still blocks
center-only.
Task 7 (refactor RegisterLiveEntityCollision) was implemented and
visually tested, but reverted because the new per-part BSP shape
didn't actually fix the door bug. The infrastructure stays — it's
correctly modeling retail's CPhysicsObj-with-parts model — but the
shapes we feed it need to be re-investigated apparatus-first.
Three hypotheses ranked: (A) part BSPs are visual-only, no collision
polys; (B) building BSP has a wide doorway gap our tiny cylinder
doesn't fill; (C) retail uses Setup.Radius/Height directly. Next-
session move: dump GfxObj 0x010044B5's PhysicsBSP first, then cdb
retail at a doorway.
Recommends: stop speculation, build apparatus, decide fix from
evidence.
#99 stays OPEN. Slice 1's "Closes #99" claim was premature; the real
close requires the per-part BSP work + correct shape identification.
