smoke_floor_geometry_cache failed in Validate run 36875756451 on one check,
ac2cPreviewWallStandsWhereAFreshCardDrawsIt, with every area check green.
The check read the moving wall only from the live layer (data-kind
"preview"). A host render during a held drag ends that layer: updated()
commits it, and nothing repaints it until the next accepted move. The
settled scene then draws the preview record itself, and its walls equal
those of a fresh card on that record. In the smoke, the "Room updated"
toast from the AC1 rename expires 3.5 s after the save, about when the drag
starts: locally the rename-to-drag gap is 3.47-3.6 s. On a faster runner
the expiry landed after the last move, so the check found no live path. A
light toggled in Home Assistant mid-drag gives the same red.
The drag now starts once the toast is gone, so the live frame normally
judges the live layer. If a host render still lands, the check judges the
settled union the same way; a stale union has none of the moved faces. A
new check takes the settled frame on purpose: a state change during the
held drag, then the union path and the areas must equal the fresh card's.
The live strips never pass through the floor-geometry caches, so the old
check stayed green with a floor key that ignores the preview. The new
check fails on that key, and a failure prints a diagnostic line naming the
judged layer and whether the settled union is the stored one.

The physical bodies, the wall union pool, the inner room contours and the
clean floor carried the global config epoch in their keys. Every edit of
any floor bumps it, so after one edit every other floor was cold again:
in large-house the first visit to an untouched floor rebuilt its wall
union and paid ~0.7 s flat / ~0.65 s 2.5D instead of ~40-55 ms.
A floor's geometry reads only its own config record (spaceModels) and
constants, so the key is now a content fingerprint of that record
(src/floor-geometry-key.ts), remembered per epoch and per record object.
The geometry also reads the current floor's config next to the model it
is given; when those records differ the key covers both. The live resize
preview is its own record, so preview frames get their own key; the
editor runtime seeds the pool and re-keys the bodies through the same
reader. The stairs editor no longer clears the clean floors of every
floor: the stairs are part of the floor's record.
The #735 switch-cycle guard now also sees the union pool and the inner
contours (optional members of the large-house card contract, so an older
comparison bundle reads 0). smoke_floor_geometry_cache proves the warm other floor and the
invalidation against an independent card (multi-floor push with shared
walls, a stair, a resize preview and its cancel); two mutants guard it.
