The residual 150–200 ms tasks are one space's wallBodiesGeometry — a
single polyclip union that cannot be split — not the aggregate the issue
is about. The threshold now names them and leaves room for a slower CI
runner; the mutant that computes everything in one task still produces
~1.5 s and fails.
Issue: #509
User-Visible: no
On the CI runner the smoke went red without any mutant: the observer was
started before the 60-room plan had finished drawing, and that render —
a long task of its own, unrelated to this issue — landed in the window.
The smoke now waits for a quiet main thread before it starts watching,
prints what it measured, and allows up to 450 ms per task: the residual
150–200 ms slices are one space's masonry union, which polyclip cannot
split, while the mutant that puts the whole aggregate back into one task
still produces ~1.5 s.

Moving the aggregate out of render fixed the first frame, but the work
itself was still one uninterrupted ~1.5 s task on the large-house
fixture — the interface stayed frozen, just a moment later, which is the
same symptom the issue reports. cleanFloorAreaSteps yields after every
room; the runtime advances it with an 8 ms budget per frame and
reschedules until it finishes, so no slice outlives a frame and the
skeletons stay until the number is ready.
The smoke now watches longtask entries for the whole show, not only the
first frame: a single long task while the values are computed fails it.

Two halves of the same first paint. The panel showed «Source unavailable»
in every row until the lazy metrics chunk arrived, because value() could
not tell "not loaded yet" from "source is dead"; and metrics() ran inside
render, walking the HA registry and unioning the clean floor of every
space synchronously — 11 s on the large-house fixture.
- totalCleanFloorAreaM2 computes the space's masonry and junction
topology once per SPACE and hands them to innerContourForRoom, which
otherwise unions the whole space again for every room: 11 045 → 1 488 ms
on that fixture, same 306.3 m². The card has always done this through
its own _innerContour cache; the panel now does the same.
- Aggregates leave the render path: the first frame paints skeletons and
the work starts right after the frame is shown (timeout → rAF →
timeout, never requestIdleCallback, which under load would leave the
skeleton up for seconds). Stale memo keeps the previous number on
screen instead of flashing back to a skeleton.
- valueState() separates pending from unavailable; a pending row keeps
the same plate, grid and height and carries a pulsing rectangle the
height of the line, replaced by the value with a short fade. Reduced
motion keeps the rectangle and drops the pulse.
- Panel enter/exit animation (#505, 190 ms) is now actually visible —
the main thread is free — and the smoke witnesses it.
