The cathedral falls'' true identity, pinned by the emitter/owner dumps
and the owner''s retail-vs-ACE oracle (retail renders them perfectly):
they are EnvCell STAB-LIST statics (interior-cell dat objects, ids
minted by InteriorEntityIdAllocator) whose geometry hangs out over the
lake. Our cell-statics route submitted every interior flood cell''s
static particle owners POST-clear ("walls own depth") - true for
content that stays inside, but a straddler''s outside half meets
seal/cleared depth and splats across the vista.
Retail''s mechanism is the outdoor shadow-cell draw: an object
overlapping outdoor landcells draws during LScape::draw (DrawBlock
pc:430056-430064, once per overlapped shadow cell), so its particles
submit in the landscape scope and drain at the pre-clear boundary
flush over true terrain depth; the cell''s own turn skips them
(drawn-once). This slice ports that rule for particles: after Collect,
the interior flood cells'' static records are classified by the shared
exit-plane straddle test (extracted as SphereStraddlesExitPlane from
the #118 dynamic split); straddlers'' owners submit in the pre-clear
closure and the post-replay cell-owners union subtracts them, so every
owner emits exactly once. Also adds the [walk-emit] probe dump that
falsified the unattached-route theory.
Hermetic 6,762/0.
