264 TemporaryDirectory() and mkdtemp() calls without dir= wrote to the /tmp tmpfs, and a full tmpfs failed modules no change touched. The test package now points tempfile and TMPDIR at tmp/tests, and sets GIT_CEILING_DIRECTORIES there so git run in a scratch directory does not find the checkout above it. The package test asserts both.

"""No test downloads a release asset unless it says so.

|
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.
