The SH-probe table is 13 tag bits wide and nothing can widen it — the probe
field is the last of the u32 — so a dense interior can ask for more slots than
exist. His session hit it (`live 8192, peak 8192`), and every prop that missed
out was then tagged as plain exterior: furniture lit by the sky, which in a Dun
Morogh snowstorm reads as the weather coming indoors.
A prop that misses a slot is still *indoors*, and saying so costs no bits.
`PropSeat` names the three states a spawner can be in — `Exterior`, `Probe(slot)`
and `Matte` — and `Matte` is the exterior payload with `MATTE_INDOOR_BIT` and a
saturated lane: the room's day/night law, which is exactly what
`interior::AppliedLaw::Matte` already gives an entity whose classification finds
the table full. A dim room instead of a sunlit one.
The seat also replaces the bare `Option<u16>` the assembler took, so a caller
now says which of the three it means rather than leaving `None` to stand for
both "sky-lit" and "wanted a probe and lost".
Still true: the table can fill, and the props past it lose their room's *baked*
light. Lowering that demand (sharing by a quantized fold, or scoping the
allocation) is the next lever and wants a measurement first.
