The sweep evaluated all 703 tracks on Sunday night and found 597 that compile
and emit. The picker still carried fourteen hand-written entries, so the page
said the library was fourteen deep — the measurement existed and the surface
that needed it did not have it.

gen_setbuilder_catalog.py turns the sweep into the page's data, joined against
two things the verdict alone does not tell you: how often the driver journal
saw the track loaded (what the hands know), and how many of its sample banks
the preload plan already warms (a cold bank is not a fault, it just hiccups on
the first bar). Sample names come from setlist_samples.py, never a fresh regex.

The sweep results now live in docs/ instead of a scratchpad that dies with the
session — an artifact nobody can compare against is the preload.scd story.

Ids are repo-relative paths, not stems. Sixteen stems collide across folders
(major_nostalgia in chill and techno, all four FFF tracks in two trees) and a
stem key merged each pair into one card, silently. Picks stored under the old
stem keys are migrated on load where the stem is unambiguous.

And the Thu-24 list is a candidate arc, not a locked set. It was exported from
the builder, not decided at the desk; rehearsal decides.
