Common columns in each cap_*.npz:
rxw(complex64) — raw RX samples (one capture window)meta_json(str) — per-capture metadata: cfo_hz, pilot_rx, snr_post, etc.- (OFDM step10 only)
Yeq_data(complex64, shape(num_syms, 48)) — equalised data subcarrier symbols ready for LDPC post-decode
Filename suffix convention: _ok = packet decoded, _fail/_bg = decode failed / pure background.
