Checkpoint of the unified retail-faithful indoor render. The two-week HANG/grey is fixed and the
interior seals (live-verified by the user). Commits the session render-rewrite foundation together
with the fixes that made it functional.
- HANG fix: PortalVisibilityBuilder.Build portal flood did not terminate (the faithful ProjectToClip
near-side clip drifts per round, defeating the CellView dedup; the BFS had no bound after U.2a removed
MaxReprocessPerCell). Fix = drift-tolerant snapped/canonical CellView.Add dedup (PortalView.cs) plus
restored MaxReprocessPerCell=16 bounded re-enqueue (PortalVisibilityBuilder.cs). Re-enqueue is kept
(load-bearing for late-slice propagation, Build_ViewGrowthAfterDoneCell_PropagatesNewSlicesToExit);
only its count is capped. CellViewDedupTests added.
- Seal (DrawCells Task 2): RetailPViewRenderer.DrawEnvCellShells draws EVERY visible cell via
IndoorDrawPlan.ShellPass (was gated on the ClipFrameAssembler slot filter, leaving slot-less cells grey).
- Look-in FPS: GameWindow exterior look-in candidates limited to the player landblock +-1 (was all ~81
loaded LBs iterated every outdoor frame). No behaviour change (far cells were >48m, already culled).
Remaining dominant issue = the FLAP at transitions: viewer-cell metastability (render roots at the
camera-eye cell, which oscillates outdoor-indoor as the 3rd-person boom drifts across the doorway,
confirmed in render-sig). SEPARATE fix, NOT the DrawCells port. Full handoff + flap fix plan + tracked
follow-ups (#78 terrain, look-in-from-inside, look-in FPS, L-spotlight):

Baselines: build 0 err; App.Tests 210/210; Core.Tests 1331 pass / 4 fail (pre-existing) / 1 skip.

GameWindow.OnRender: when clipRoot != null, run only InteriorRenderer.DrawInside
(per-cell shells + per-cell objects + live-dynamics); the global entity pass +
global shell pass are no longer issued indoors. Outdoor scenery drawn clipped to
the doorway (after terrain, before the Z-clear). Outdoor root path unchanged.
pvFrame hoisted so the splice reads OrderedVisibleCells; per-frame 3-bucket
partition built on the indoor root. Retail RenderNormalMode @ 0x453aa0.
InteriorRenderer amended with a DrawableCells membership filter (an IsNothingVisible
cell can be in OrderedVisibleCells but absent from CellIdToSlot — iterate for ORDER,
filter for membership; matches the old envCellShellFilter set exactly).
Build green, 174/174 App tests pass.

Per-cell flood: closest-first over OrderedVisibleCells, per cell draws the closed
shell (EnvCellRenderer.Render(pass,{cellId})) + that cell's objects, then live-
dynamics unclipped, then transparent shells. Reuses the existing dispatcher Draw
per cell (safe to call N x/frame; only diagnostic GPU-timing miscounts). Caller
owns the landscape-through-door + Z-clear. Not yet wired (Task 3).
