sylph-decoder e88ac3a002 re: the frame-vs-audio clock run is void -- four instrument faults, control caught it ...

The estimator had to recover the plate's known 2.53 s period and returned 0.599 s,
its own search floor, meaning no peak was found. plate-pulse-measured.md already
records that this fast-rise/slow-decay waveform defeats sinusoid fitting;
autocorrelation fails for the same reason, so the trap was written down and I
walked into it.

I also reimplemented the title gate without its twelve-sample hold, so the window
straddled the build-in -- the signal ranges 0..5433 where the plate never goes
below 159. And no Looped Data lines were captured at all: Apu logging was on, but
those lines appear only on a wrap, and BGM_103's first wrap is ~96 s after the
music starts against a 90 s window.

The audio-clock result from committed data stands and is unaffected.
