docs: Campaign FW - FW2 status + the FW3 slice plan from the cutover survey

FW2 gate adjudication recorded (RecordingGpuDevice referees are the
automated gate; the pixel A/B rides FW3's cutover toggle). FW3 sliced
from the verified surface survey: FW3.1 production walk world data
(the Building record drops every walk field today - the biggest gap),
FW3.2 walk-driven static routes (stop EMITTING the three static routes;
ClipFrameAssembler/ViewconeCuller survive for the dynamic routes;
walk-path selection publication - picking is an unlisted consumer of
the static draw path), FW3.3 ShellDrawLiftZ retirement (THREE sites -
AP-32 lists only two), FW3.4 perf checkpoint with the baseline
correction (519.7 fps is the Aerlinthe ordinary profile, not dense
Arwic - capture a fresh pre-cutover dense-Arwic pair first).

+**FW3 SLICE PLAN (2026-08-30, from the cutover-surface survey):**
+
+- **FW3.1 — production walk world data.** Materialize the walk's world
+  model at landblock commit time, registry-owned, through the LEGAL
+  `IDatReaderWriter` seam (never raw `DatCollection` —
+  `RuntimeDatAccessArchitectureTests`): (a) `WalkCell` fields onto/beside
+  `LoadedCell` (portal side/exact from the RAW `Flags` already preserved
+  on `CellPortalInfo`; plane from the existing `ClipPlanes` parallel
+  list; the 0xFFFF→0xFFFFFFFF exit-sentinel widening); (b) a production
+  `WalkBuilding` build in `LandblockBuildFactory`/`BuildingLoader` — the
+  BIGGEST gap: today's `Building` drops ModelId/Frame/portal
+  flags/stab lists at load; (c) the walk landscape assembly (retail
+  z-slabs from the height table, the SideCellCount LOD pyramid,
+  `CellBuildings[]`, viewer-centred grid) fed from landblock residency;
+  (d) the production frame context: camera/rays/CyPlane/ObjectToClip
+  derived from the LIVE `WorldCameraFrame` + real viewport (the capture
+  client's 1024×720 constants are fixture pins, not production values).
+  Conformance: the ten oracle fixtures re-run against the PRODUCTION
+  builders (same DATs → identical walk output as the test adapter).
+- **FW3.2 — walk-driven static routes.** `WorldSceneRenderer` drives
+  `RetailFrameWalk` → `OrderedDrawStream`
+  (Terrain/BuildingShell/CellStatic/LookInStatic/PortalPunch stages) →
+  `SubmitOrderedStream` for static content; the old builder STOPS
+  EMITTING `LandscapeOutdoorStatic`/`LandscapeBuildingShell`/`CellStatic`
+  ranges (the `CompletePackedProductionFrame` count assertion forbids
+  emit-but-skip); dynamic routes (`LookInObject`,
+  `LandscapeOutsideDynamic`, `DynamicLast`) stay packed — which requires
+  `ClipFrameAssembler` + `ViewconeCuller` to SURVIVE this stage (their
+  slices key the dynamic routes). Walk-path SELECTION publication
+  (static picking today rides `publishSelection: true` in the packed
+  classifier — an unlisted consumer; the walk submitter must feed
+  `RetailSelectionScene` or statics go un-clickable). Portal-punch
+  emission via `PortalDepthMaskRenderer` at walk turns; building-detail
+  overlay replay; sky/weather move from per-slice to the walk's
+  landscape turn; the `_drawCullModes`/alpha-scope sequencing constraint
+  resolved (own cull scratch or strict sequencing). Route-keyed particle
+  owners re-sourced from the walk.
+- **FW3.3 — ShellDrawLiftZ retirement.** THREE sites (the register row
+  AP-32 lists only two — `LandblockBuildFactory.cs` bakes the lift into
+  the drawn cell transform and is unlisted): delete all three, flip the
+  #130 proof (`UnliftedGate_LeavesTheStripAtTheDrawnTopEdge` is
+  explicitly written to fail-by-gap until the lift is gone), delete
+  AP-32 in the same commit.
+- **FW3.4 — perf checkpoint + gates.** BASELINE CORRECTION: the
+  519.7 fps / 1.869 / 1.096 ms numbers are the Aerlinthe
+  ordinary-production profile, NOT dense Arwic. Before the cutover
+  lands, capture a fresh dense-Arwic pre-cutover baseline with the same
+  harness (`tools/run-connected-r6-soak.ps1 -Uncapped -DenseTown`), and
+  apply the ±20% stop rule to THAT pair. Transition checklist: the
+  lifecycle gate + dense-town soak exist; a Holtburg house-exit stop and
+  a teleport stopwatch metric must be ADDED to the lifecycle route
+  (`drive.ps1` from the spec does not exist — the checklist runs on the
+  existing gate scripts).

 ### FW4 — entities, particles, dynamics into walk turns; delete the apparatus
