Appends the OPAL Festival 2026 section to the archivist's log: floor reactions
per track, transitions, and the sound/technical notes, each paired with what the
measurement said.

The pairing is the point. Where PLN's ear and the meter agree, that is a
calibration datum:
  "not loud enough, i had to set max volume"  -> -18.2 LUFS, 4.2 dB under target
  "MAFIA bass goes too high for a few secs"   -> +24.5 dB over local median,
                                                60-250 Hz, at 1:02:10 (he filed
                                                it at 1:03:10 — one digit off)
And where they disagree, that is more interesting still: Mafia got a strong
floor reaction while being the NARROWEST (width 0.05) and most bass-dominant
(78% in 60-250 Hz) track of the night. Width is not what makes these land.

Near-miss worth recording: I first wrote this file with Write, having been told
twice by a stale tool cache that it did not exist. It did — 319 lines including
the entire Take89/Montreuil listening pass. 314 lines were destroyed and
recovered from HEAD. The corpus CLAUDE.md calls a documentary source survived
because it was committed.
