The moving-fixture divergence was the building degrade ladder:
GfxObjDegradeInfo::get_degrade @0x0051e4b0 (Ghidra-verified - BN's
FPU-flag pseudo-C misread BOTH arm selection and one formula) slides
each level's threshold from ideal toward MAX as the multiplier
approaches 1, and the live client runs the positive arm at ~0.99, so
level 0's portal-bearing BSP survives to ~max_dist (48 for the Holtburg
cottages), not ideal (24). The recon note's "deg_mul = -0.99" was a
sign misread; the negative arm's threshold slides toward MIN and
contradicts the fixtures from both directions. With the two-arm port,
holtburg-walkout, holtburg-transitions, and holtburg-walkabout pass
every pairable frame - the walkout-F2 microscope's prediction
(103,100 | 100x3 | 124 through the cottage exit views) landed exactly.
Also this round, falsified and reverted: a BN-driven swap of the
portal walker's negative/in-plane arms (Ghidra shows side 1 = negative
EMITS, side 2 = in-plane does not - the original port was correct; the
swap broke four fixtures). The walker docs and unit tests now pin the
Ghidra-verified truth table.
Parked with findings: foundry-entry F67 (right flood set, one
plane-side classification at the +/-eps boundary orders 11d before
116/118) and doorway-still (retail shows zero floods at a pose one
meter from walkout-F2's flooding pose; multi-portal clip boundary).
Suites: Walk 124/3 skips; hermetic 6,687/0.

Three final pins complete the still-fixture set: (1) the CELL portal
side decode is the INVERSE of the 0x2 bit (uniform with the building
convention; the doorway-still flood proved it - ov=2 n=3 exact, and
foundry-deep stays green); (2) interior frames key the landscape order
off the OUTSIDE-projected landcell (get_outside_cell_id - derived from
the camera origin); (3) the outdoor pview has draw_landscape=FALSE so
look-in floods discard exit portals - the ov=0 pattern of every traced
look-in. CONFORMANT: foundry-deep (every frame), doorway-still,
street-outdoor, terrace-center, terrace-edge (the #456 acceptance
pose), cathedral-arrival - full frames identical to retail. The moving
four diverge only at punch-edge frames (walkabout F9, foundry-entry
F67) - pose-timing sensitivity parked in the driver Skip note.

Three pinned corrections close the outdoor frame: (1) the camera basis
RE-pinned to +Y-forward - the terrace-edge fixture EXTERNAL ground
truth (the ledge faces the F518 vista, east) overrules the walkabout
motion sweep, whose camera was mouse-turned off the run line; (2)
alwaysDrawObjects (.data default 1 @0x00820ed4) drawn into the
DrawSortCell gate - cell contents draw for every cell of an in-view
block; (3) the building portal side decode data-pinned as the INVERSE
of the cell 0x2 bit (the sweep winning arm). Street result: all 13
buildings in retail exact order (a9b3003c in, aab50002 correctly
absent), punches at exactly 001a and 0022 opening the exact first
cells 16e/164. SOLE remaining delta: look-in flood depth (mine 1 cell,
retail 3-4) - the doorway-still fixture adjudicates the interior flood
in isolation next.

UpdateViewerDistance @0x0050e030 + get_degrade @0x0051e4b0 ported with
live-pinned globals: distance measured to the part SCALED SORT CENTER,
effective = max(0, dist - s_rDegradeDistance [live 100]), level = first
with effective < IdealDist (the live auto_update_deg_mul<=0 arm), else
the last level. WalkBuildingDegradeLevel carries the full authored
bands; the adapter fills sort centers; the replay context measures to
the transformed sort center. Sweep state after the rule: the level-0
building set is now correct; the residual divergence is the per-portal
side/clip gate (my arms punch a near-complement of retail two) - the
sweep driver carries the next instrument in its Skip note.

The offline degrade probe proved the mechanism: every Holtburg building
carries PORT nodes ONLY in its level-0 GfxObj (out to ~24-48 m); every
degraded level has zero. Retail walks the CURRENT degrade level BSP
(part->gfxobj[deg_level]) - that is what limits look-in punches to the
nearest buildings. WalkBuilding gains the degrade ladder +
SelectDrawingBsp (band pick; UpdateViewerDistance hysteresis is a port
TODO), the walk selects per viewer distance, the adapter builds
per-level BSPs, and the stab-list load rule (CLandBlock::init_buildings
@0052fd80: a full-res block loads exactly its buildings portal stab
cells) replaces load-everything in the landscape builder. The sweep now
shows clean rosters with all far-building punches gone; remaining
deltas: the near buildings 001a/0022 (50 m/28 m center distance vs the
48 m band edge - sphere-adjusted distance/hysteresis to port) and the
one ring-1 frustum boundary pair (aab50002/a9b3003c).

RuntimeDatAccessArchitectureTests correctly flagged WalkWorldDatAdapter
taking raw DatCollection in production. The adapter is the conformance
harness world builder, so it moves into the test assembly; the FW3
production adapter will consume the content-owner seam. Hermetic suite
back to 6,687/0; adapter + conformance 10/10.

The replay harness reconstructs the camera from a pose-stamped oracle
frame (Frame quaternion w,x,y,z storage order; +Y forward / +Z up;
landblock-local origin) and drives the ported walk over adapter-built
cells (cell transforms from EnvCell.Position now populated). The
foundry-deep fixture - the pure-interior frame shape - reproduces
retail EXACTLY on every complete frame: DI + DC(ov=0, [cell]) with no
landscape, 39/39. Conventions are now pinned by live retail output; the
remaining nine fixtures need the outdoor world build-out (landscape
blocks, terrain z-slabs, building transforms + active-view clip) and
join the same gate.

WalkWorldDatAdapter builds WalkCell/WalkBuilding from real DATs: cell
portals with the PortalSide flag bit and signed OtherPortalId, portal
polygons + planes via the production formula, stab lists, building
position cells (24 m landcell math), building portals with stab lists,
and the drawing-BSP -> WalkBspNode conversion incl. PORT-node PortalRef
polygons (the previously missing consumers the 2026-08-30 survey named).
Lane=InstalledDat conformance: every BLD id the FW0 oracle traces saw
retail draw (26 buildings over 7 landblocks) resolves in the adapter
roster at its EXACT position cell; the traced look-in cells build with
portals/polygons/stabs; the sanctuary BSP carries portal refs. 9/9.

RetailFrameWalk composes the ported machinery into retail frame shapes:
SmartBox::RenderNormalMode rooting (camera-cell low word < 0x100),
PView::DrawInside + the DrawCells event half (interior pview, the
traces pv=009d4a80), LScape::draw (per-view visibility, blocks
far-to-near, per-block cells far-to-near, buildings at their cell turn)
and RenderDeviceD3D::DrawBuilding (BLD at entry before the degrade
check; two-pass BSP portal walk per active view on the outdoor pview,
the traces pv=009d4b08). WalkLandscape ports the block grid +
draw_check_blocks/landcell_check visibility (192 m/24 m pitch,
viewer-relative, union across views, never downgrade). Six composition
tests: outdoor far-to-near emission, degrade-entry event, interior
ov=0/ov=1 shapes, rooting, complete view unwind.

PView::ConstructView overload @0x005a59a0 (side must EQUAL the authored
portal_side, clip survival, Visible destination, punch on pass 1, flood
recursion on pass 2). Punch surfaces via the pass sink for FW1
conformance; the depth-fan submission itself is FW2. Six tests: BSP
emission order both viewer sides, in-plane suppression, pass-1
punch-no-flood, pass-2 flood + DC event, sidedness rejection, unloaded
destination skip.

WalkScreenClip chain. Resolves and documents the portal-flag convention
(inflag=1 = the portal FACES the viewer and feeds max_indist; inflag=0 +
armed seen = an opening — the same side condition building look-ins
require), which the PDB names obscure. WalkWorld supplies the cell model
and frame-context seam. Six synthetic-world flood tests pass on first
run: traversal, facing rejection with the exact distance key, exit-view
raising, entry-portal no-ping-pong, chain ordering, unloaded skips.

the keep/last/stl/second pruning bookkeeping with all three closing
wrap checks, <3 reject leaving dest untouched, cap 31, pool-base reset
at view_count==0, retail fabs on copy, and edge planes
N=normalize(cross(ray[k+1],ray[k])), d=-dot(N,eye) behind an

The second decomp round (flood bookkeeping/propagation, view-clip
support, landscape visibility) is archived Ghidra-arbitrated - it caught
a load-bearing BN inversion (InsCellTodoList pops NEAREST-first, which
is what makes the draw list far-to-near) and three more traps (the 192m
elided constant, the min/max double positional swap, the copy_view
cross order - the walk doc section 6 is corrected). WalkVisibilityMath
ports get_pt_limit @0x0054b840, get_clip_height @0x0054cff0,
corner/block_plane_check @0x0054b930/@0x0054d060, block_check
@0x0054dc50, and viewconeCheck @0x0054c250 with retail boundary
semantics (strict cull, inclusive partial, touch-out=Outside /
touch-in=EntirelyInside) under 23 focused tests.

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.

LandWalkOrder ports LScape::get_block_order @0x00504c50 (near-to-far ring
list, walked backwards by LScape::draw), CLandBlock::calc_sq_draw_order
@0x0052f4a0 (cell array filled backwards from the closest cell),
LandDefs::get_dir @0x005a9aa0, and the 9-case closest-cell direction
switch. The shared 8-slot ring coefficient tables were byte-decoded from
the PDB-paired binary (block VA 0x0081cc6c.., cell VA 0x0081df88.. -
identical sets); the intra-ring visit order is preserved exactly because
it decides draw order between equidistant blocks and the oracle traces
pin it. Thirty focused tests cover coverage/ordering invariants, the
hand-expanded ring-1 pattern, and the direction/closest-cell contracts.
