Retail draws cell geometry at the dat EnvCell origin verbatim; the
0.02 m lift was our z-fight stand-in (register row AP-32, deleted in
this commit). With the walk owning retail draw ORDER under
WorldDepthContract Less (first-drawn-wins: DrawBlock terrain-then-
objects per cell, DrawCells shells-then-contents), the coplanar
tie-breaks the lift compensated for are now resolved the way retail
resolves them.
Deleted at every site: the PortalVisibilityBuilder const + the
drawLiftZ Build parameter and its lifted exit-portal projection branch
(gate and drawn geometry now share ONE space); the seal/punch fan
lifts (DrawPortalDepthWrite + the walk's DrawWalkPunchFan); the
LandblockBuildFactory drawn-cell-transform lift (render and physics
share the one verbatim transform).
The #130 proof flipped exactly as its own doc predicted:
UnliftedGate_LeavesTheStripAtTheDrawnTopEdge is deleted (its premise -
gate space != drawn space - no longer exists), and the renamed
ExitDoorTopEdge_GateCoversTheDrawnApertureWithinPixelTolerance sweep
(147 eye/gaze combos at the Holtburg corner door) passes with both in
the same unlifted space (worst plane gap <= 1.2 px, scissor <= 0.15 px
- unchanged tolerances). Ten more replay-test call sites swept to the
new Build signature.
Suites: full Release build 0 warnings; hermetic 6,750/0; the 21
affected InstalledDat replay tests green; Walk conformance 40/1
untouched.

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).
Suites: full Release build 0 warnings; Walk lane green; hermetic green.
