#118: outdoor dynamics draw in the outside stage under interior roots - the house-exit clip+vanish was the SEAL z-killing the player

Root cause (pinned by the new deterministic exit-walk harness, NOT guessed):
under an interior render root, the exit-portal SEAL stamps the door fan at
TRUE depth after the gated full depth clear, and T1's "ALL dynamics last"
pass then drew the outdoor-classified player depth-tested - every fragment
beyond the door plane z-failed against the seal across the whole aperture.
Harness measured the full window: from the moment the sphere center crosses
the plane until the eye follows (~2.6 m of camera lag, ~2.2 s at walk speed)
the player is invisible; while straddling, the beyond-plane body half clips
at the plane. The handoff's three cone-level candidates are all EXONERATED:
the cone walk passes every step; (eye, ViewerCellId) come from the same
SweepEye call with camera-update-before-visibility-read in the same frame;
the side-test window is sub-epsilon under healthy resolution.

Retail oracle (grep-named-first): PView::DrawCells 0x005a4840 runs
LScape::draw FIRST (pc:432719), then the gated depth clear (pc:432731-32)
and the exit-portal seals (pc:432785-86); outdoor cell objects draw inside
the landscape stage (DrawBlock 0x005a17c0 -> DrawSortCell pc:430124), and
an object draws once per overlapped shadow cell (pc:430056-64) - the
straddling body composes from both stages, neither half clips.

Fix: RetailPViewRenderer assigns dynamics to the OUTSIDE stage under an
interior root when outdoor-classified OR sphere-straddling an exit-portal
plane of their flood-visible cell (DynamicDrawsInOutsideStage - pure, the
harness drives it as the ordering contract); they ride the landscape slice
draw (pre-clear, seal-protected) with the same per-slice cone test as
outdoor statics. Indoor dynamics keep the last pass (retail loop C);
straddlers draw in both (retail shadow dual-draw). Outdoor roots keep
all-dynamics-last - the BR-2 punch-after-dynamics lesson (88be519) stands.

Apparatus: HouseExitWalkReplayTests - dat-backed corner-building exit walk
driving the production stack headlessly (RetailChaseCamera damping ->
healthy-sweep viewer resolution -> PortalVisibilityBuilder.Build ->
ClipFrameAssembler -> ViewconeCuller -> the DrawDynamicsLast predicate +
a CPU seal-depth model). 5 tests: cone pin, seal-depth pin, straddle
dual-draw pin, per-step table, stale-root window quantifier (#118 cand 2).

Suites: App 232 (227+5), Core 1416+2skip, UI 420, Net 294.

 ## #118 — Character clipped + disappears for a moment when exiting houses
 
-**Status:** OPEN
+**Status:** FIXED 2026-06-11 — pending visual re-gate
+
+**Root cause (pinned by the exit-walk harness, `HouseExitWalkReplayTests`):**
+NOT the cone stack — candidates 1–3 all exonerated (cone-level walk passes
+every step; the camera publishes (eye, ViewerCellId) from the SAME SweepEye
+call and updates before the visibility read, so the pair is coherent; the
+side-test window is ≤ PortalSideEpsilon and never occurs under healthy
+resolution). The mechanism is DEPTH ORDERING: under an interior root, the
+exit-portal SEAL stamps the door fan at TRUE depth after the full depth
+clear, and T1's "ALL dynamics last" then draws the outdoor-classified player
+depth-tested — every fragment beyond the door plane z-fails against the seal
+across the whole aperture. Full vanish once the center exits (harness: the
+entire s=0.04→2.64 m window until the eye crosses, ~2.2 s at walk speed);
+the body's beyond-plane half clips at the plane while straddling.
+
+**Retail oracle:** PView::DrawCells (0x005a4840) runs LScape::draw FIRST
+(pc:432719), THEN the gated depth clear (pc:432731) + seals (pc:432786);
+outdoor cell objects draw inside the landscape stage via DrawBlock →
+DrawSortCell (0x005a17c0, pc:430124), and an object draws once per
+overlapped shadow cell (pc:430056-430064) — so a threshold-straddling body
+draws in both stages and neither half clips.
+
+**Fix (`RetailPViewRenderer`):** under an interior root, outdoor-classified
+dynamics draw in the OUTSIDE (landscape) stage — before the clear+seal, so
+the seal protects their pixels — and indoor dynamics whose sphere straddles
+an exit-portal plane draw in BOTH stages (`DynamicDrawsInOutsideStage`).
+Outdoor roots keep all-dynamics-last (the BR-2 punch lesson). Pins:
+`ExitWalk_PlayerStaysConeVisible_EveryStep`,
+`ExitWalk_PlayerSurvivesSealDepth_WhenConeVisible`,
+`ExitWalk_StraddlingPlayerDrawsInOutsideStage`.
