A fixture is a real project the suite installs and measures. There are seven. Each page below says what the project is, what installing it exercises, and which variations apply to it.
Every fixture directory carries its own vlt.json, which points installs at
the benchmark registry mirror and makes the fixture its own vlt project root, so
an install never resolves the surrounding repository instead.
Six fixtures take the install variations. run takes only the run variation —
run-run is the only *-run.json pair anywhere in the archive. next is the
only fixture currently scheduled for build and build-cache, but 10 dates
between 2026-05-09 and 2026-08-03 ran those for all six install fixtures, so the
archive holds astro-build.json and friends. Which pairs
actually exist for a given day is discoverable from the data — see
../METHODOLOGY.md.
