`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.

cli.py 345 -> 222 and _verifier.py 347 -> 228, via _cli_checks.py and
_verifier_support.py.
The cli seam cut straight through code covered by its per-file-ignores.
Rather than copy S607 and PERF203 onto a second entry, both are fixed:
systemctl is resolved with shutil.which, and the readiness poll no
longer carries a try/except in its body now that the probe is its own
function. Both ignores are deleted from meta/pyproject.toml and ruff
passes without them - the repo has two fewer suppressions than before.
The which() fix adds a systemctl-is-None branch, so the pass count goes
216 -> 217: one new test for it, no existing test touched. Coverage is
back at 100% by covering the branch, not excluding it.

_challenge.py 467 -> 236. The two flows and run_coding_challenge go to
_challenge_flows.py; the three static prompt strings to
_challenge_prompts.py, which covered the last eleven lines after the
first cut landed at 261.
The 13 patch strings in test_challenge_part3.py were repointed per test,
by which function is under test - the _run_user_impl tests keep
_challenge. Getting that wrong does not fail here, it HANGS: an
unintercepted _collect_and_rate_tests ran the real interactive flow and
spun the suite for two minutes. Runs are now under an explicit timeout,
and the patch targets are asserted to resolve before pytest starts.
Pass count is 216 before and after.

New python_pkg/code_tutor package that turns an unfamiliar codebase into
an interactive lesson: analyse code into items (_analyzer), order them
dependency-first (_plan_builder), pose reimplement challenges
(_challenge + _challenge_support), verify user implementations with tests
and coverage (_verifier), track progress (_progress/_session), and offer
local-LLM hints (_llm), driven by a Typer/Rich CLI (cli).
- meta/pyproject.toml + .pre-commit-config.yaml + meta/requirements.txt:
add anthropic/rich/typer deps, a cli.py per-file-ignore (Typer B008 etc),
and code_tutor-specific ruff/pylint/mypy tuning.
- _challenge.py and its tests are split across _challenge_support.py and
test_challenge_part2/part3.py to stay under the 500-line file cap.
Verification: pytest 631 passed at 100% line+branch coverage; every file
<=500 lines; pre-commit (ruff ALL, mypy strict, pylint 10/10, bandit,
evidence + multi-file contract) green.
