Resolves the plan §3 open questions with the user this session:
- object/entity/particle draw = LITERAL PER-CELL LOOP (retail DrawCells),
not a global MDI batch with per-instance clip. Fidelity > perf > blast-radius.
- sequencing = HOLISTIC: build the per-cell DrawInside directly; no intermediate
global-pass gate-fix. First visual gate = sealed cottage interior, no bleed.
- terrain in the seal = FAITHFUL: drawn only through the exit-portal clip, never
as a floor under the interior. Inventory's 'relax Skip' suggestion REJECTED as a
non-retail workaround; grey-floor = a sealing bug (verify cell mesh in R1).
- WB mesh pipeline KEPT (per-cell draws from the global buffers, batched within a
cell); two-camera invariant preserved (eye projects, player cell roots visibility).
Phases (holistic): R1 unified per-cell DrawInside (the core) -> R2 outside-looking-in
(DrawPortal) -> R3 dungeons -> R4 polish+cleanup. Each ends GREEN + a user visual gate.
Retail anchors cited throughout (RenderNormalMode 0x453aa0, DrawCells 0x5a4840, etc).
