GitHub Actions step uses a mutable tag or branch reference. Tags and branch names can be silently repointed by the action owner, enabling supply-chain attacks — as seen in the trivy-action and kics-github-action compromises. Pin the reference to a full 40-character commit SHA instead, e.g. uses: actions/checkout@8ade135a41bc03ea155e62e844d188df1ea18608.

## Individual Comments
### Comment 1
<location path=".github/workflows/tests.yml" line_range="217" />
<code_context>
- channels: conda-forge
- channel-priority: strict
- python-version: "3.12"
+ environments: "test-py313-pyside6"
- - uses: tlambert03/setup-qt-libs@v1
</code_context>
<issue_to_address>
**issue (bug_risk):** The workflow prepares the `test-py313-pyside6` environment but invokes the nonexistent `py313-pyside6-conda` environment, so `pixi run` fails before the test task starts.
**Suggested fix:** Invoke `pixi run -e test-py313-pyside6 test` or rename the configured environment to match the command.
```suggestion
run: pixi run -e test-py313-pyside6 test
```
</issue_to_address>
### Comment 2
<location path="pixi.toml" line_range="62" />
<code_context>
+[environments]
+default = { features = ["py312", "pyside6", "test"] }
+
+# Standard python x backend (pyqt5 across all Pythons for the comprehensive base)
+test-py311-pyqt6 = ["py311", "pyqt6", "test"]
+test-py312-pyqt6 = ["py312", "pyqt6", "test"]
</code_context>
<issue_to_address>
**nitpick:** The comment says these are PyQt5 environments, but every environment in the block uses the `pyqt6` feature; the comment therefore gives maintainers incorrect guidance about which backend is being tested.
**Suggested fix:** Update the comment to say PyQt6.
```suggestion
# Standard python x backend (pyqt6 across all Pythons for the comprehensive base)
```

Track pixi.lock for reproducible CI.
.gitignore excludes pixi.lock, so checkout does not provide it. The pinned setup-pixi action defaults locked to false when no lockfile is present. Commit pixi.lock, remove the ignore rule, and set locked: true.
