IN (retail-faithful):
- Growth propagation is IN PLACE, never by re-enqueue: retail
AddViewToPortals (Ghidra 0x005a52d0) enqueues only on first discovery
(InsCellTodoList); growth into a popped cell runs AdjustCellView -
re-clip ONLY the new views through that cell's portals immediately.
ProcessCellPortals + the processedViewCounts watermark port exactly
that; the MaxReprocessPerCell=16 drift cap is DELETED (the 1-px merge
is the physical fixpoint floor). Depth-128 tripwire logs loudly if the
convergence invariant ever breaks (failsafe, not control flow). Same
restructure in BuildFromExterior.
- Reciprocal-empty culls strictly (retail OtherPortalClip returning
nothing = the opening is invisible from the neighbour's side); the
eye-in-opening pre-clip restore is gone.
- Look-in seeds: retail ConstructView(CBldPortal) IN_PLANE reject at the
TRUE F_EPSILON (SeedInPlaneEpsilon=0.0002, const @0x007c8c70) + the
full-screen substitute rescue DELETED (the verifier-flagged non-retail
bypass that admitted floods retail strictly rejects).
REFUTED BY THE CONFORMANCE GATE (attempted, reverted, documented inline):
- PortalSideEpsilon 0.0002: retail's tight epsilon assumes the viewer
cell transits the instant the eye crosses a plane; our root can lag
~1 cm at pressed corners (CornerFloodReplay failed at every step -
0x0171/0x0173 chain dead). 0.01 KEPT as the documented root-lag
tolerance; tighten only with eye-exact viewer tracking + cdstW.
- Deleting the clip-empty eye-in-opening rescue: same gate, same total
failure - our ProjectToClip near-eye behavior (EyePlaneW=1e-4) diverges
from retail polyClipFinish's UNPINNED cdstW constant. Rescue KEPT as
the documented cdstW-gap compensation; re-attempt only after pinning
cdstW from the binary.
Gates: App 226/226 green (CornerFloodReplay + MeetingHallFlood + the
collapsed-portal pin all pass); Core baseline unchanged (1398 + 4
pre-existing #99-era). CloneViewPolygons orphan removed.
