`requires-python` and the CI pin already said 3.14, but ruff, mypy and pylint were still grading `meta/` against 3.10 -- three tools judging an interpreter nothing runs any more, and ruff withholding the pyupgrade fixes that only become safe at the newer target. `pin_ci_python.py` rewrites these three knobs. What the stale target was hiding: `datetime.timezone.utc` where `datetime.UTC` is now correct (UP017), and ruff's stable formatter applying PEP 758 -- `except (A, B):` becomes `except A, B:`. That makes the source 3.14-only at the syntax level, which is what `requires-python = ">=3.14"` already promised; kuhy chose it deliberately over holding ruff a release back (2026-08-29). Also drops a comment in `wsg_grabber/models.py` that the bump makes false: it explained why the file used ``str, Enum`` instead of ``StrEnum`` under mypy at 3.10, sitting directly above a ``class Verdict(StrEnum)`` that had already stopped obeying it. ruff, ruff-format, mypy --strict and pylint all clean at the new target.
