PLN said snare was 'also a default tidalcycles CC0/public domain pack'.
Upstream disagrees: tidalcycles/Dirt-Samples tracks 52 files under sn/ and
zero under snare/. The 90-file snare bank is local and was unidentified.

His second memory was the one that paid — 'the very early tidalcycles docs
pointed me to that sample pack'. The banks come from slab.org/tmp/samples-extra.zip,
the Tidal Club course pack from Week 1 lesson 2. Proven by reading the zip's
central directory over a range request, so 113 MB stayed on the server:
SNARE0, SNARE119, KICK142, CLAP163 are all in it, and the local folder is
named samples-extra.

Three candidates died on dates and names, which is worth recording so nobody
re-runs them: Blood Sport prefixes its banks bs- and holds no SNARE*.wav; the
90s-sample-cds torrent was downloaded 2024-12-20, after these files' 2019-11-07
mtime; MF_Drums_Samples names its files BD_MF_Valve11.wav. And there is no
content-based route at all — AcoustID needs song-length audio, not 0.4s hits.

The uncomfortable part: this makes the ledger worse, not better. The pack ships
no licence for these banks — the only licence file in it is Blood Sport's own.
And snare's files carry ISFT 'Sonic Foundry Sound Forge 6.0', IENG 'TJ', ICRD
2003-08-30, i.e. 24-bit one-shots rendered on a 2002 commercial DAW. An official
course pack establishes provenance, not licence.

So kick, cleared on 2026-08-16 on the note 'TidalCycles official / samples-extra
CC0 pack', rests on the same unverified premise. Same pack, same absent licence,
but cleared is releasable and unknown blocks. One question to yaxu settles six
banks at once.
