With the debug-frame fix the BigBuf download now returns clean sample frames (verified on
hardware: offsets 0..N, real envelope data, then ACK). But identify downloaded a fixed
15000 bytes while the acquisition captured 12288 samples (98304 bits / 8), so the tail was
BigBuf memory past the samples (heap / the 0xDEADBEEF stack canary) — which flagged as
"garbage" and poisoned the demod.
read_emitted now sizes the download to lf.read()'s reported count (firmware returns the
size in BITS; /8 = samples at 8 bits/sample); read_config downloads the readbl acquisition
span. No trailing memory -> the demod runs on clean samples.
