Poem

A bunny taps the matrix key,
Adds 3.14 with glee.
NumPy markers hop in line,
Changelog notes now neatly shine.
CI nibbles on a path unquoted—
All tests burrow, greenly noted. 🐇✨

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Out of Scope Changes Check	⚠️ Warning	The change to .github/workflows/cd.yml adjusting the subject-path input for the attest-build-provenance action is unrelated to enabling Python 3.14 testing as described in the linked issue.	Please remove or separate the workflow modification into its own pull request, so this PR focuses solely on enabling Python 3.14 testing.

.github/workflows/cd.yml (1)

40-40: Clarify the connection to Python 3.14 support.

The removal of quotes around dist/* appears unrelated to enabling Python 3.14 testing. While both quoted and unquoted glob patterns are valid, this stylistic change is not mentioned in the PR description or objectives.

Could you clarify whether:

1. This change is intentionally included as a related fix/improvement?
2. There was a specific issue with quoted paths that this resolves?

If this is an unrelated change, consider moving it to a separate PR for clearer change tracking.

CHANGELOG.md (2)

12-14: LGTM!

The changelog entry properly documents the Python 3.14 testing enablement with correct formatting and attribution.

---

50-50: LGTM!

The PR reference link is correctly added to the links section.

noxfile.py (1)

31-31: LGTM!

The addition of Python 3.14 to PYTHON_ALL_VERSIONS correctly enables testing on this version for both the tests and minimums nox sessions.

pyproject.toml (1)

62-62: LGTM!

The Python 3.14 classifier is correctly added to the project metadata, aligning with the testing enablement.

Poem

A whisk of ears, a hop of cheer,
We’ve added 3.14 this year!
Nox now knows the path to tread,
NumPy markers neatly spread.
Artifacts glide through CD’s door—
My paws applaud: “Test some more!” 🐇✨

.github/workflows/cd.yml (1)

40-40: LGTM! Correct glob pattern syntax.

Removing the quotes allows the glob pattern to be correctly interpreted by the attestation action, rather than being treated as a literal string.

12-14: LGTM! Changelog entry follows the project conventions.

The entry is properly formatted and placed in the "Unreleased" section with appropriate references.

---

50-50: LGTM! PR reference link is correctly formatted.

noxfile.py (1)

31-31: LGTM! Python 3.14 added to testing matrix.

This change enables testing on Python 3.14 as stated in the PR objectives.

pyproject.toml (2)

62-62: LGTM! Python 3.14 classifier added.

The classifier correctly declares support for Python 3.14.

---

44-47: No updates needed for numpy version constraints. numpy 2.3.2 exists, supports Python 3.14, and has no relevant security advisories.
