The live retail cdb trace decided it: retail roots at the connector 0118 at the
grey pose (NOT the PICK fork) AND still draws the player room 0116 from that root,
because retail's InitCell side test reads the dat PortalSide bit where acdream's
render path reconstructed the interior side from the cell AABB centroid (mis-sides
a thin connector). ISSUES #186 -> CLOSED; handoff gets a RESOLVED banner.

Retail SEAMLESS at the same spot (user-confirmed) => real acdream bug: the eye seats
in a sparse 5-poly connector cell 0xF6820118 looking back at the player's room 0116,
and acdream drops 0116 (back-portal side-culled) so the doorway aperture shows the fog
clear color = grey; retail keeps 0116 drawn. RULED OUT: null-root/AD-20/AD-21 (root
valid, eyeInRoot=Y); the color-clear gating (retail's gated DrawCells Clear is
depth/stencil, post-LScape::draw). Next step = retail cdb trace (viewer_cell +
cell_draw_list at the grey pose) to pin viewer-cell PICK vs portal FLOOD, then a careful
frozen-render fix. Full handoff + apparatus + DO-NOT-RETRY + code/decomp sites in the doc.
Keeps the offline cell-geometry inspection test.
