Two independent lenses over a 63-minute handheld stage-mic MP3, for a night with
no stems and no gig-log. They agree where they can both see, and where they
disagree the reason is structural rather than mysterious.

Confirmed by both lenses, independently:
  0:00-5:04   bombe                 z=2.33 margin 0.67 + diams_dj 85% offset consistency (1056/1244)
  31:27-35:46 take5_drops           z=1.91 margin 0.58 + take5 cons 0.38
  8:54-11:28  something_about_drums              + movie_paris cons 0.49

Crossmatch alone, but with margins strong enough to stand:
  11:33-16:58 am_i_doing_it_right   margin 0.87
  18:13-22:32 you_my_sunshine       margin 0.82
  48:25-51:20 punkachien            margin 1.06  <- only findable because Montreuil supplied the render
  38:31-41:41 piment_bresilien      margin 1.19
  51:30-54:10 mafia                 margin 0.69
  57:29-60:29 vague_de_crime        margin 0.82

The two disagreements are the interesting part, because they are predictable.
crossmatch can only name a track it holds a prior render of, and  is
confident about two banks that have none: rose @31:20 at 0.602 consistency
(rose_rouge played neither gig) and love_parade @56:10 at 0.399 (livecode_parade
is NEW — its .tidal was created in the CosmicFest prep commit itself, so no prior
render can exist). Trust locate there. The fix for next time is one render per
new track and the reference set covers it forever.

Recorded as gaps rather than answers: blue_gold wins four short scattered
segments at margins 0.11-0.44, and that scatter is the signature of a fallback,
not a performance — material with no matching reference lands on whatever is
nearest. Segment edges come from a 45s median filter so they are +/- 20s and are
NOT cut points; bounds.html and ears do that job.
