The CI runner sets XDG_CONFIG_HOME to its own home, and the installer now reads it as RetroArch does. Tests that fake HOME then found the runner's RetroArch folders. The suite clears the three XDG variables it reads, and a test that exercises one sets it itself.

The CI job sets RETROBIOS_OFFLINE, but a local run of the documented command

did not, and e2e fixtures queried the large-files release and wrote its

answers into the shared .cache/large. A test that serves its own assets

clears the variable for itself.

Scratch files go under the repository's tmp/, which git does not track: a

fresh clone has none, and a module run alone raised FileNotFoundError on a

temporary directory instead of naming the missing parent.
