Doc-and-reality sync before the session handoff: the plan's phase
sections read future-tense while T1-T4 landed them. The render digest
carries the authoritative ledger; this stamp points there and names the
4 pre-existing #99-era Core failures as BR-7's built-in acceptance
signal.
'I don't care if it is non-playable... I want everything ported, then we
test.' Per-phase playability + per-phase visual gates DROPPED. BR-2..BR-6
execute as ONE continuous port with build+tests green per commit and a
single comprehensive visual pass at the end (T5). Replaces the
playability rule with: every installment must be a COMPLETE retail
behavior, never half of one (the BR-2 punch-without-ordering lesson,
88be519).
The plan's BR-1 ('implement the skipNoTexture draw-time surface gate')
died on its pre-check: acdream ALREADY suppresses every portal fill.
ReplicateProductionEmission_OnPortalFills replicates the exact emission
conditions of the production extractors on the hall/cottage fills:
pos=False neg=False for every one (Stippling.NoPos skips the positive
side at ObjectMeshManager.PrepareGfxObjMeshData:1046,
PrepareCellStructMeshData:1394, CellMesh.Build:44, GfxObjMesh.Build:71;
the fills have no negative surface). There is nothing to gate.
What ships instead: StipplingSurfaceEquivalenceTests - 2,607 polys across
13 building models + 13 environments, ZERO violations both directions:
NoPos <=> untextured-surface. Our build-time skip is proven equivalent to
retail's draw-time skipNoTexture rule (Ghidra 0x0059d4a4, default on
@0x00820e30) on this content. The pin fails loudly if future content
breaks the invariant - the cue to implement the draw-time gate then.
Corrections folded into the plan + comparison docs:
- The #113 phantom residual CANNOT be GfxObj fills (they never reach a
vertex buffer). Plausible true sites are cell-side: flood-admitted
cells drawn with the pass-all NoClipSlice when slot-less
(RetailPViewRenderer.cs:71), and/or cell statics drawn unclipped +
un-viewcone'd (object-lists-skip-portal-view-gate, confirmed).
BR-2 opens with the probe that pins which.
- The e46d3d9 user-gate observations (filter removed phantom/doors) were
confounded - the filter was a provable mesh no-op on shells AND doors.
- Ledger rows solid-surface-skip-missing + the acdream half of
portal-polys-baked-unconditional re-marked REFUTED-for-fills; the
retail mechanism descriptions and the un-consumed PortalIndex->
CBldPortal pairing (BR-4) stand.
Suites: Core 1398 green (1392 baseline + 6 new facts) + the 4 pre-existing
#99-era failures + 1 skip. No production code.

Names the boundary of what BR-1..BR-8 delivers, so the gaps are written
down rather than silently assumed (the very thing that breeds whack-a-mole):
FU-1 transparency/sorting (BR-9 candidate, area unmapped), FU-2 dungeon
visibility scaling #95 (plausibly helped by BR-4/BR-6 but NOT guaranteed -
re-measure after), FU-3 LOD/degrades, FU-4 picking, FU-5 the ~30 open
questions (in the comparison doc $6), FU-6 verification top-up before
BR-8b lighting. None blocks BR-1..BR-8; each becomes its own item.
The #95 dungeon-scaling follow-up was previously raised only verbally -
now tracked in the plan. Sections 4/5 renumbered to 5/6.

Deliverable 1: docs/research/2026-06-11-building-render-acdream-vs-retail-
comparison.md - the acdream-vs-retail architecture comparison synthesized
from two ultracode mapping fan-outs (11/12 areas, ~90 agents, every retail
claim Ghidra/pc-cited, every acdream claim file:line, 40/76 divergences
adversarially verified so far; raw per-area evidence committed under
docs/research/2026-06-11-holistic-map/).
Headline findings: (1) retail flattens GfxObjs/cells at load exactly like
us (ConstructMesh + RemoveNonPortalNodes) - the MDI pipeline survives;
(2) the phantom/door mechanism is the skipNoTexture draw-time surface gate
(dat-confirmed); (3) retail never geometrically clips world geometry -
aperture exactness is a DEPTH discipline (punch maxZ1 / seal maxZ2 / gated
clear + far-to-near whole-mesh draws) - reframes #114; (4) flood admission
is already faithful, the trigger/depth/multi-view/cone-culling layers are
missing; (5) #115 root cause verified (boom damping severed from the
published collided viewer); collision A6.P4 design verified with
corrections (signed other_portal_id >= 0 gate).
Deliverable 2: docs/plans/2026-06-11-building-render-port-plan.md - the
phased port plan (BR-1 surface gate, BR-2 depth punch/seal, BR-3 delete
the shell chop, BR-4 draw-driven floods, BR-5 viewconeCheck, BR-6 one
gate, BR-7 collision A6.P4, BR-8 camera/lighting/LOD) with per-phase
acceptance criteria, bug closures, keep-list, and a playable-after-every-
phase migration order. AWAITING USER APPROVAL - no implementation.
