The indoor doorway flap is the portal flood's re-enqueue churn (0171<->0173 mutual re-contribution; drifted near-duplicate regions AddRegion won't dedup -> grew -> re-enqueue, capped at MaxReprocessPerCell=16 -> eye-sensitive flood depth -> grey flash). Confirmed live: launch-churn-confirm.log shows maxPop=16 on 44% of frames during a doorway walk-through. The 2026-06-08 'maxPop=1, churn refuted' verdict was a camera-turn-at-rest capture (wrong reproduction); its DO-NOT is overturned.
Fix (Option A, user-approved): contributions already covered by the neighbour's accumulated view don't grow it (no re-enqueue); only the uncovered remainder propagates -- retail's 'redundant -> empty before copy_view' (copy_view confirmed to just append). Remove MaxReprocessPerCell; keep re-processing of genuinely-new slices. Scope: PortalVisibilityBuilder only. Revives 2026-06-08 spec+plan (banners redirected).

Point both at the Option-A full-retail-port handoff so a fresh session can't follow the dead plan.

The writing-plans decomp pass read FixCellList (433407) -> AdjustCellView (433741)
-> ClipPortals(update_count) + AddViewToPortals, proving retail RE-PROCESSES a
grown-after-drawn cell. So the approved "enqueue-once / no re-process" approach is
wrong (it would break Build_ViewGrowthAfterDoneCell for the right reason — that test
is actually retail-faithful).
Corrected approach (user chose the faithful moderate port over an epsilon-dedup
band-aid): KEEP re-processing on growth, but BOUND it the way retail does — each
view slice processed once (monotonic update_count watermark) and redundant
reciprocal back-contributions clip to EMPTY (OtherPortalClip -> no copy_view -> no
new slice), so the reciprocal/drift loop can't churn. acdream churns because its
reciprocal yields a drifted non-empty sliver, bounded only by the
MaxReprocessPerCell=16 hack. Remove the cap; bound structurally.
Scope unchanged: PortalVisibilityBuilder only; no rooting/camera/clip-math-rewrite/
seal change. One open precision (exact line where acdream's sliver becomes
non-empty — float-drift-dependent on real geometry) deferred to the plan's first
task: instrument PortalVisibilityBuilder (per-pop re-pop count + reciprocal-clip
in/out + grew), capture at the doorway, pin it, THEN fix.
Spec updated in place with a REVISION banner; superseded enqueue-once body retained
for the audit trail.

The 2026-06-08 AM "physics rest micro-jitter" diagnosis is refuted with primary
evidence (door-recheck 216K standstill records: 0 position re-snaps; player
byte-stable during the flap). Two adversarial verification sub-agents confirmed:
- Retail roots the render at the camera viewer_cell (swept from the player via
SmartBox::update_viewer 0x453ce0; DrawInside(viewer_cell) 0x453aa0) and toggles
DrawInside / LScape::draw -- so acdream's eye-cell rooting + inside/outside
toggle are RETAIL-FAITHFUL. The locked-design "root at player cell" is wrong.
- The flap is render membership instability, eye-motion-driven: the visible-cell
set oscillates (8<->3) as the eye sweeps monotonically. Root = the
re-enqueue-on-growth DRIFT (PortalVisibilityBuilder.cs:322, MaxReprocessPerCell
=16) re-clipping each grown cell every round -> sub-cm eye jitter flips membership.
Fix (spec, not yet implemented): verbatim port of retail's enqueue-once flood
(ConstructView + AddViewToPortals): enqueue once on first discovery, clip each
cell's portals once, union late growth in place (AddToCell) + draw-reorder
(FixCellList), never re-enqueue. Kills the drift; rooting/camera/seal untouched.
