Profiling #694 found three costs on every View pass, paid even with the
summary panel hidden.
The summary panel read the safe-area probe's computed style in layout(),
which the card reaches up to five times per render (renderControls,
menuItems, renderPanel twice, the clock check), and its updated()
measured the stage, probe and kiosk buttons after every DOM commit. The
insets now live in the measured state: measureLayout is the only method
that reads style or layout, and updated() calls it only when an input of
the measurement changed (probe, kiosk buttons or stage element, title,
language, mode, kiosk, kiosk scale, narrow, HA theme), after connect()
or an identity change, on visibility, once after document.fonts.ready,
and from resized() as before. A floor switch or an HA tick no longer
measures.
The _model getter rebuilt the config fingerprint (a walk over every
space and room with JSON.stringify of room settings) on each of its
dozens of reads per render. ConfigFingerprintPass remembers the whole
cache key (epoch and fingerprint) from the start of willUpdate() to the
end of render() while the epoch, the config object and its spaces array
are unchanged. Remembering only the fingerprint and concatenating the key
on every read was tried first: in 2.5D on the large house the switch cycle
measured slower than without any memo, and CPU profiles showed several
times more garbage collection on load and on the first visit of a floor;
one remembered key per pass has neither. Outside the pass (handlers, updated(),
timers) every read still builds the key, so an in-place edit without an
epoch bump stays visible (HP-1454-04). No write to the fingerprinted
fields is reachable from willUpdate() or render().
_isoScene read the stage box during render only to feed an aspect into
the overlay fit, whose frame has not depended on the aspect since #713.
It now uses the frame's own aspect and passes stageSize: null.
render-layout-read.mjs now also judges _isoScene and the whole summary
runtime except measureLayout, forbids layout property reads
(clientWidth, offsetTop, ...) besides the two calls, and reports every
violation. Two registered mutants restore the old reads.
No visible change: panel caps, side, offsets and kiosk clearance are
computed from the same values; the 2.5D frame is the same.

T1: demo/serve.mjs exports check/checkAll/finish — all 48 smokes now
assert named facts and exit non-zero on a mismatch or an uncaught
in-card exception (verified by breaking the kiosk guard on purpose).
Informational values were frozen from a v1.43.1 run and cross-read
against the source; timings assert budgets, not exact numbers.
T2: new CI job 'smoke' gated on 'frontend', builds a FRESH bundle
before running (the committed demo/srv/assets copy is a snapshot) and
uploads per-file logs on failure.
T3: [auto] now means 'a named failing check exists' and each line names
it (43 lines); 72 aspirational markers honestly downgraded to [manual].
Fixed the 'ZERO edit buttons' contradiction (wrong since v1.30.1) and
the opening-click line (true again since v1.43.1).
Three smokes carried pre-v1.39.0/v1.25 expectations and were testing
old behaviour: tap defaults for lights, card-wide tap action, label drag
requiring plan mode.
DEVELOPMENT.md documents the harness contract.
L1: memoized space model + open pairs (structural fingerprint key, epoch
bumped synchronously at mutation time, not inside the debounce); hoisted
per-room geometry out of the render loop; smoke asserts zero recomputation
across state pushes.
L4: openings get the 3 px drag threshold used by every other pipeline and
only write when the geometry actually changed — taps open the dialog again.
G2: interiorPoint() replaces the vertex mean, so island rooms inside
concave (U/L) parents are accepted and their evenodd holes render; traced
duplicates still are not containment.
G3: segKey rounds before ordering — one shared wall, one key.
B2: _check_write fails closed when the entry is unavailable.
B3: layout/set honours expected_rev and returns the new rev.
B4: config/set without expected_rev over a non-empty store logs a warning.
B5: coordinates reject NaN/Infinity; spaces/rooms/markers/decor/layout capped.
