monad02_coex-03_20260909-231527

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

monad02, profile coex-03, 2026-09-09 23:15 to 23:24 (9 minutes), 1 segment. Claimed by EXP-009 (primary, matched by session).

Counts and yields

Records	43,262
Frames the radio saw	44,686
Empty records	2,677
useful_yield	0.9082
capture_yield	0.9681
Empty share	0.0619
Mean rate	93.6 Hz
Bytes	30,285,096
Band / channel / width	2.4 GHz / 3 / 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

What the channel carried, by tone count and modulation. A bandwidth is printed only when every frame of the class named the same one.
