- ANCHORS support (slug, end_line) to bound bleeders (mephisteuf/opal-2025/
  38c3-toilet) into clean blocks — no more swallowing neighbour setlists.
- clean_track_line: strip leading set-position labels (Intro:/Finale:/Sunset),
  keep 'Label: Name' / drop 'Name: gloss'; recovers the LIVE-Noctambule pattern.
- leet_fold fallback (B00K→book, T01l3ts→toilets, G00D→good) — resolves only
  after a straight miss so genuine digits (sept1) still match first.
- 9 gap gigs recovered (opal-2024 14/14, algolia-fdlm 26/26, 39c3 13/14…).
- 6 mechanical tests (leet, label, gloss, bpm/transition, ascii/comment skip,
  real-backlog coverage guard). 59 pass.
