PLN-flagged chain of labeling errors, traced to the SSOT classifier:
- 'jazz' was matched to BREAK, but jazz is a multisample KIT (jazz:0=kick,
  :1=snare/hat…). A folder name is not a reliable family signal: it may be one
  family, a heterogeneous kit, or a demucs grab named after a SOURCE song
  (wap, take5, the_revolution, xplosive, rample*). classify_sample_family now
  fires ONLY on names that lexically encode an instrument; everything else is
  None (= needs per-sample analysis). No 'kit registry' (that's name-guessing too).
- removed over-reaching genre/source tokens: jazz, dnb, jungle, loop from break;
  drum from perc. This also FIXES jungle_pads (→pad, was break) and
  jungle_vocals (→vox). amen kept (amencutup genuinely is the Amen break).
- tempo: strip Tidal '--' line comments before parsing cps (ton_numero's
  commented-out morpher no longer counts); a track with a live 'cps (range …)'
  is now flagged morph even when it also declares a fixed setcps. morphing=1
  (Septembre 1er, 60→180), was 0.
- report: + stage_tempo_by_year, sources/roadmap, recurrence gig_slugs,
  classified/unclassified coverage (21% of palette uses need analysis, honest).
- tests: classifier refuses kit/source names; jungle_pads→pad guard. 60 green.
