monad02_rate-ladder-48_20260902-070341

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

Counts and yields

Records	2,217,799
Frames the radio saw	2,245,937
Empty records	56,668
useful_yield	0.9622
capture_yield	0.9875
Empty share	0.0256
Mean rate	654.3 Hz
Bytes	1,552,460,708
Band / channel / width	5 GHz / 48 / 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.

Record classes

No record class: the lake has not decoded this session's frames, so nothing is known about what the channel carried.
