Master: 61.0 min, 2 ch, 48 kHz, 24-bit. I = -14.0 LUFS on the nose, peak
-0.9 dBFS under a -1.0 ceiling, LRA 12.7 LU. L-R difference RMS is -22.4 dB, so
it is genuinely stereo and not dual-mono — worth measuring rather than assuming,
given the first attempt collapsed to one channel.

THE BUG THAT WOULD HAVE SHIPPED. take-master trims leading silence before
loudnorm sees it, so the master starts 10.94 s later in the music than the raw
take does. The segments were computed against the RAW take. Splitting with
unshifted offsets puts every boundary eleven seconds late — each track beginning
eleven seconds into the previous one's tail. The output would have played
perfectly and been wrong throughout.

Two guards in take-segments:
  --shift   subtract the measured head trim. Clamped at 0, because the first
            track legitimately goes negative: PLN focuses a .tidal a few seconds
            BEFORE he evaluates it (log says 7.4 s, first sound is at 10.94 s).
  --master  probe the mastered file and clamp to its duration. The master is
            trimmed at the TAIL too (1.45 s), so without this the last segment
            ran past EOF and ffmpeg would have written a short final track in
            silence.
Now: contiguous, starts at 0, sums to 3661.2 s — exactly the master's length.

AND A SHADOWING BUG FOUND WHILE FIXING IT. The per-segment loop bound `start`
and `end`, the same names as the take window, so the summary line printed the
LAST SEGMENT as if it were the whole take: "1970-01-01 01:55 — 5.1 min". The
segments were correct the whole time; only the report lied. That is the kind of
defect that ships, because the payload looks right and nobody re-reads a header.

GENERATIVE METADATA, per PLN's ask, derived not typed:
  title    backlog.md via setlist.py (the SSOT reaches the ID3 tag)
  TBPM     backlog BPM, NOT setcps — reference_tempo_from_audio, setcps is not
           felt tempo. gimme_acid is setcps 80 played as 160 half-time DnB, and
           you_my_sunshine is setcps 144 against a felt 166. Tagging 80 would
           have been a measured number that misleads.
  grouping the set section (Ouverture / SUNSET / NuJazz / NUIT)
  comment  orbit inventory from the .tidal via pvlint's parser, plus the source
           path, so any track can be traced back to the code that made it

Metadata says REHEARSAL, not gig: album "OPAL 2026 — rehearsal, J-6", date
2026-08-02, no venue, no lineup, no poster (feedback_metadata_vs_mastering — gig
metadata is canonical only in Web/www/next/content/lives/).

lime_tacos is track 7 at 1:49. He played it, then cut it from the set an hour
later. The take records what happened, so it stays, tagged "not in the final
set".
