`requires-python` and the CI pin already said 3.14, but ruff, mypy and pylint were still grading against 3.10/3.11 -- 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), `socket.timeout` where `TimeoutError` is (UP041), 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). ruff, ruff-format, mypy --strict and pylint all clean at the new target.
