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.
