format_measure_value() does not exist; the shared SI-prefix formatter is
format_measure(double, const std::string&) at src/ui.cpp:1004.

The spec described the new condition fields as appended session keys. LayoutState
carries no trigger field at all -- the trigger is built from --holdoff and the
panel's defaults on every launch -- so there was nothing to append to. Persisting it
is a separate feature nobody asked for, and a session that silently restored an armed
pulse-width condition would surprise rather than help. The statistics toggle stays as
the one session key this design adds.

The spec claimed a window condition with equal levels degrades to an edge trigger on
that level. It does not: the band test is a change of side, so equal levels make the
signal "inside" only on exact float equality and the condition silently never fires.
Special-casing the detector into an edge trigger would conflate two state machines
that answer different questions -- the divergence the shared evaluator exists to
prevent. The panel refuses the degenerate band instead.

Qualified trigger conditions (pulse width with glitch as a comparison, window,
dropout), per-measurement statistics with a reset, and a search over the retained
ring. The first and third are the same question asked of live and of recorded data,
so they share one allocation-free EventDetector extracted out of TriggerEngine --
and the probe that proves the two paths agree on t0 is part of the scope.
Reference waveforms, PNG export, FFT and a byte-bounded event history are out, each
for a stated reason.
