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.
This commit lands VERIFIED GROUNDWORK + design only:
- spec: docs/superpowers/specs/2026-06-08-portal-flood-enqueue-once-port-design.md
- findings: docs/research/2026-06-08-flap-physics-diagnosis-REFUTED-its-render-membership.md
- [pv-input] probe gains rawPlayer + yaw (disambiguates the varying input)
- 4 GREEN physics rest-stability tests (prove rest is bit-stable -> flap not physics)
- apparatus: launch-flap-capture.ps1, analyze_flap_live.py, find_burst.py
- captured fixtures: tests/.../Fixtures/flap-doorway/0xA9B4017{0..5}.json
