monad04_exp-c1-ambient-44_20260901-021457

In plain words A library keeps three lists: what was delivered, what was catalogued, and who checked it out. A measurement corpus needs the same three, and a gap between them is a fact about the pipeline, not about the room. This is the ledger, per day and receiver, with every session as a row you can open.

The rate ladder

monad04, profile exp-c1-ambient-44, 2026-09-01 02:14 to 02:17 (3 minutes), 1 segment. Claimed by EXP-F1 (primary, matched by session).

Counts and yields

Records	26,945
Frames the radio saw	27,717
Empty records	1,488
useful_yield	0.9185
capture_yield	0.9721
Empty share	0.0552
Mean rate	150.7 Hz
Bytes	18,861,500
Band / channel / width	5 GHz / 44 / HT20

Quote useful_yield: (records − empty records) ÷ frames the radio saw. capture_yield counts an all-zero record as delivered. A low capture_yield on 2.4 GHz is DSSS/CCK traffic that yields no channel estimate, not a quiet channel. Both are derived ratios from two independent counters and exceed 1.0 on some sessions; the counts are exact, the ratios are not.
