Partitioned at the section banners each file already used, into ten new
modules named for what they cover. python_pkg/code_tutor is now entirely
under the cap, from thirteen violations.
The splitter copies the whole original header into each new file and
lets ruff's F401 pass prune it - 59 imports removed correctly, versus a
hand-written import block failing on every earlier test split today.
That does not cover module-level helpers: _make_verifier sat between two
banners and was left behind by its callers, so it moved to conftest.py,
taking test_verifier.py's shadowing copy of _make_live_mock with it.
No patch string changed. Pass count is 217 before and after.

_llm.py 295 -> 217, clearing the last code_tutor source violation; only
its seven test modules remain over the cap.
The seam falls between the two backends because each pins a different
plain import: test_llm.py patches requests.post on _llm for
OllamaBackend and anthropic.Anthropic for ClaudeBackend. _llm keeps its
own anthropic import - complete_with_fallback still catches APIError -
so the four anthropic patch strings were split per test rather than
moved wholesale.
Pass count is 217 before and after.

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.

_analyzer.py 388 -> 226. The file walk, dotted-name map, import
resolution and fingerprint go to _deps.py; the skip frozensets and the
function regex to _scan_tables.py, which covered the last nine lines
after the first cut landed at 259.
_is_binary is the only name any test patches on _analyzer and it stays
put, so no patch string needed editing. Only test_analyzer.py's import
block had to be split.
Pass count is 216 before and after.

_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.

_challenge_support.py 402 -> 237. _pytest_clean and _patch_and_test go
to _pytest_runner.py with the subprocess/os/sys imports they solely used;
_stream_verdict and _parse_verdict go to _verdict.py with rich's Live.
code_tutor patches by absolute string rather than a MOD constant, so the
seam cost 15 per-name rewrites instead of one sed. Two intermediate
failures caught by running it: the test modules import the moved names
directly, and five patch strings still named the old module.
Pass count is 216 before and after.

test_codebase_fingerprint_stat_oserror_raises passed on 3.14 but failed
on CI's 3.11: there Path.is_file() itself calls stat() and re-raises an
OSError without a recognized errno, so the injected error escaped before
the loop reached the guarded path.stat() call. Force is_file() True for
the target (without calling stat) so the explicit fingerprint-time stat()
deterministically raises and hits the except OSError branch on every
Python version. Verified passing on 3.11.11 and 3.14.

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.
