His verdicts, verbatim: "jungle breaks is a open domain cd, h2o is hydrogen oss
drum machine, kick risers are from the tidalcycles officials or samples-extra
cc0 packs, and vec1/2 come from offered free packs".

Recorded against 10 banks rather than 5, because the same source answers more
than the bank that prompted the question: org_jungle_breaks shares its CD,
h2ogmcp and h2ogmcy are the same Hydrogen GM kit as h2ogmhh, and vec1_acid and
vec1_snare are the same VEC pack as vec1_claps. Each carries the source in its
note, so the reasoning survives the session that produced it.

This is what ranking by leverage was for: five answers moved 60 banks from 19
clear to 29, and the four heaviest gates in the record (14, 9, 9 and 8 tracks)
are now open. 31 remain, and the next one down is `snare` at 4 tracks — likely
the same CC0 family as kick and risers, but that is a guess and a guess is
exactly what this ledger exists to not record.
