📝 Walkthrough

Walkthrough

This PR addresses typos and clarifications across four test files: correcting spelling in comments (referece → reference) across regression metric tests, adding a clarifying comment to a module replacement test, fixing a mistyped test argument in a lookup option test, and correcting a docstring typo. All changes are cosmetic or correctness adjustments with no logic modifications.

Add docstrings to helper functions.

Helper functions lack docstrings describing parameters, return values, and purpose. Per coding guidelines, all definitions should have Google-style docstrings.

In `@tests/utils/test_look_up_option.py`:
- Line 75: The test uses look_up_option("empty", _CaseEnum) which actually
matches and returns _CaseEnum.EMPTY so the test's expect(ValueError...) is
wrong; change the input back to the near-miss "empy" (or alternatively update
the assertion to expect a successful return of _CaseEnum.EMPTY) so that
look_up_option triggers the error path with suggestion; update the test case
referencing look_up_option and _CaseEnum accordingly to either supply "empy" to
assert the ValueError message contains the suggestion or assert that "empty"
returns _CaseEnum.EMPTY.

Test will fail with this change.

When "empty" is passed to look_up_option(_CaseEnum), the function matches it against enum values and returns _CaseEnum.EMPTY successfully—no error is raised. The test expects a ValueError with "did.*empty" pattern. The original "empy" (near-miss) triggers the error path with a suggestion. Revert to "empy" or rewrite the test expectation.
