docs: plan progress — Task 2 done; cutover flip de-risked + precisely specified

Shell pass is a safe no-op for the node id (no exclusion needed); indoor->outdoor
terrain already works via OutsideView; the only new piece is feeding the outdoor
ROOT node's full-screen region to OutsideView. Remaining = OutsideView integration
(read ClipFrameAssembler) + clipRoot flip + launch + visual gate.

+  de-risked by reading the draw path:
+  - The shell pass is a **safe no-op** for the synthetic node id — `DrawEnvCellShells` →
+    `_envCells.Render(pass, {id})` renders nothing for an id with no prepared geometry
+    (`RetailPViewRenderer.cs:190-202`). So **no explicit shell-exclusion is needed.**
+  - Indoor→outdoor terrain **already works** via the existing `OutsideView` → terrain-slice
+    path (`DrawInside` → `DrawLandscapeThroughOutsideView`, `RetailPViewRenderer.cs:79,138`).
+    The ONLY new piece is the **outdoor-ROOT** case: when `DrawInside` is rooted at the
+    outdoor node, the node's full-screen view region must become an `OutsideView` slice so
+    terrain draws full-screen. → Read `ClipFrameAssembler` (how `pvFrame.OutsideView` becomes
+    `OutsideViewSlices`; how a full-screen region maps to a no-clip terrain slice), then in
+    `PortalVisibilityBuilder.Build` (or `DrawInside`): when the root is the outdoor node
+    (`SeenOutside` + outdoor id), `AddRegion(frame.OutsideView, <full-screen NDC quad>)`.
+  - Then flip: `viewerRoot = _outdoorNode` when outdoors; `clipRoot = viewerRoot` always
+    (drop the `playerIndoorGate && viewerRoot != null` gate at `GameWindow.cs:~7346`). This
+    routes EVERY frame through `_retailPViewRenderer.DrawInside` (the `else` outdoor block
+    becomes dead — leave it for the post-visual-gate delete).
+  - **Build → launch (`ACDREAM_PROBE_FLAP` only) → USER VISUAL GATE** at the cottage. Then
+    delete `BuildFromExterior` / `DrawPortal` / the dead `else` block / `OutsideView`-only
+    plumbing (Task 7) + cleanup (Phase 4).
+  - **WARNING:** this is coordinated surgery (Build + ClipFrameAssembler + GameWindow) that
+    ends at a launch + visual gate; a first attempt rarely renders right. Do it with adequate
+    context headroom (the dead-zone regression came from rushing a render change before a
+    visual gate). Verify the [outdoor-node] probe shows real portals FIRST.
