monad03_crowd-day-48_20260828-120135

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.

monad03, profile crowd-day-48, to (119 minutes), 24 segments. Claimed by EXP-C1 (primary, matched by session).

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.
