Additive, nothing invokes it yet (the cutover flip is step 2):
- WalkProductionLeafRenderer + RetailPViewPassExecutor.WalkLeaf: the
walk driver's leaf turns over the SAME executor renderers the packed
path uses today - DrawWalkSky (the per-slice sky block looped under
one driver turn), DrawWalkTerrainSlice (the terrain block of
DrawLandscapeSlice), per-cell shells via EnvCellRenderer,
DrawWalkPunchFan (PortalDepthMaskRenderer far-Z, +ShellDrawLiftZ
matching today's DrawPortalDepthWrite until FW3.3 retires it), the
alpha barrier via FlushLandscapeAlphaFartherThan, and caller-supplied
clear/seal actions (the renderer owns the pass scope). The cutover
changes ORDER, never leaf mechanics.
- Punch fans now carry the ACTIVE VIEW INDEX end to end (retail pins
building_view = Render::portal_view_num @0x0059f3bf for the whole
two-pass walk; the fan clips by that view's slice planes):
PortalPassSink.ActiveViewIndex -> IWalkEventSink.OnPunchGeometry ->
IWalkFrameLeafRenderer.DrawPunchFan.
- The FW3.2b-2 rooting design is recorded in the plan (dual-compute
split, LookInObject route filtered to dynamics, consumer
re-pointing, gate list).

The oracle trace order DI|DC|LS is breakpoint-ENTRY order; retail's
actual DRAW order inside PView::DrawCells @0x005a4840 for an interior
root is LScape::draw FIRST (pc:432719, only when exit views survive),
then the depth clear (pc:432731-432732), the exit-portal seals
(pc:432785-432786), THEN the flood's own cells far-to-near. The
driver drew flood cells before the landscape - inverted.
RetailFrameWalk.DrawInside gains the additive
OnInteriorFloodDrawTurn(cells) hook firing after the conditional
landscape turn; the DC EVENT stays at its original point (conformance
untouched - 40/1 InstalledDat green). WalkFrameDriver records the
interior flood at the DC turn and draws it at the new turn:
flush -> ClearInteriorDepth -> flush -> DrawExitSeals -> per-cell
shell-then-contents. Building look-in floods still draw immediately at
their building turn (retail's reentrant DrawCells with no clear/seal).
Two new leaf members map to IWorldPassScope.ClearInteriorDepth and the
seal-fan machinery at FW3.2b-2. Reconciliation note recorded: the
driver clears unconditionally for interior roots while production
stages the clear on OutsideViewSlices>0 - observably equivalent at
ov=0, awaiting a firmer decomp read of the clear's gate.

WalkFrameDriver executes one full static-content frame from the walk's
turns so GPU command-buffer order equals retail's walk order. One rule
does the interleaving: the accumulated OrderedDrawStream flushes
through SubmitOrderedStream immediately before EVERY non-stream draw
(sky, terrain slice, cell shell, punch fan, alpha barrier).
Turn script, all decomp-cited and two of them corrected in review:
- Interior flood: per cell IN FLOOD ORDER, shell first then contents
(PView::DrawCells @0x005a4840: DrawEnvCell @0x005a4abe precedes
DrawObjCellForDummies @0x005a4b0d).
- Landscape: sky once, terrain per active slice, then blocks
far-to-near; per cell the building turn precedes the cell's outdoor
statics (DrawSortCell @0x0059f140).
- Building (DrawBuilding @0x0059f2a0): the BLD probe event stays at
entry, but the ENTIRE body - alpha barrier, portal passes, shell -
sits inside retail's gfxobj[deg_level]!=0 gate @0x0059f2d3, and the
order is FlushAlphaList @0x0059f30b -> the two-pass punch/look-in
walk -> THEN the shell draw @0x0059f345. The driver review caught
both the missing gate and a shell-before-punch inversion; fixed
with the addresses cited.
Walk seam: three additive default-implemented IWalkEventSink hooks
(OnLandscapeCellTurn / OnBuildingTurn / OnBuildingShellTurn /
OnPunchGeometry) - every existing sink and all FW1 conformance
fixtures unchanged. WalkLandBlock gains LandblockId for the cell-id
encoding. Leaf draws go through IWalkFrameLeafRenderer so FW3.2b-2
wires the real renderers and the referee suite runs on fakes +
RecordingGpuDevice.
Flagged for FW3.2b-2/FW4 adjudication (documented in code):
FlushFartherThan(building distance) vs retail flush-all
FlushAlphaList(0f); terrain-before-statics within the landscape turn.
Suites: full Release build 0 warnings; Walk lane 200/1 skip;
InstalledDat Walk conformance 40/1 untouched; hermetic 6,752/0.

WalkEvent mirrors the FW0 oracle-trace vocabulary one-to-one (Landscape,
Building, DrawInside, DrawCells) as the conformance surface RetailFrameWalk
emits; the FW2 ordered draw stream layers on later without changing it.
