docs: holistic building-render port charter + next-session prompt (the 2026-06-11 mandate)

Browse source 
User mandate: stop bug-by-bug; map acdream-vs-retail for building draw,
interiors, interior collision, dynamics, clipping, culling; plan the port
of retails drawing discipline once and for all. The handoff carries the
branch state (124c6cb, nothing on main), the full evidence inventory from
this session (orphan no-draw polys, door-vanish mystery, draw-side clip
status, straddle gate), the gap map, tooling (Ghidra MCP 8081 correct
PDB, live cdb protocol, dat dump + flood harnesses), the investigation
charter (workflow fan-out per subsystem, adversarial verification), and
the paste-ready new-session prompt. #113 marked REOPENED and folded in.

## #113 — Phantom exterior staircase (Holtburg meeting hall): PView shell clip was never GL-enabled — [FIXED 2026-06-10 · 927fd8f + scope 9ce335e; outdoor half user-verified 2026-06-11]
## #113 — Phantom staircase: REOPENED 2026-06-11, folded into the HOLISTIC BUILDING-RENDER PORT
**Status:** REOPENED — root cause #2 found (drawing-BSP-orphaned no-draw polys:
hall model 0x010014C3 keeps its walkable stair-ramp as dict polys {0,1}, in the
PhysicsBSP, referenced by NO DrawingBSP node — retail never draws them, we
iterate the dictionary). The mechanical filter (`e46d3d9`) removed the phantom
everywhere (user-verified) but made DOORS vanish across Holtburg → un-applied
(`124c6cb`, helper + dat pins kept). Per the user's 2026-06-11 mandate ("solve
this holistic once and for all"), #113/#114/#108/#109/the door mystery/#99 are
now ONE effort: map acdream-vs-retail for building draw / interiors / interior
collision / dynamics / clipping / culling, then port retail's drawing
discipline. **CHARTER + paste-ready next-session prompt:**
[docs/research/2026-06-11-building-render-holistic-port-handoff.md](../research/2026-06-11-building-render-holistic-port-handoff.md).
The shell-clip work below remains in (outdoor-scoped) and correct.
### (history) PView shell clip was never GL-enabled — 927fd8f + scope 9ce335e
**Status:** FIXED (self-gated by screenshot comparison at the original spot —
phantom gone; formal user visual gate pending)
