228 ruff findings to 0 across the notebook, its partial export and twm.py, and
mypy --strict is clean on both .py files.
A notebook is a deliverable that happens to contain code, so the check that
mattered was not "does it still run" -- it needs a GPU, MNIST, CIFAR-10 and a
slice of Quick, Draw! to run at all -- but "is anything except the code still
exactly as submitted". Hashing every key of the .ipynb EXCEPT cell `source`
gives 60242e116d12549d11c93f7f before the first edit and after the last one,
across four passes and a `ruff format`. The file also round-trips byte-for-byte
through json.dumps(indent=1, ensure_ascii=False), which is what made editing
cells programmatically safe rather than a reformat of all 141 of them; the
diff touches 38.
print() became sys.stdout.write() rather than logging. In a notebook the print
IS the output, and a logger with no handler configured would have silently
emptied every cell -- the exact regression scripts/check_refactor_safety.py
was written for. matprint's `print(x, end=" ")` and bare `print()` are
preserved as writes with and without a trailing newline.
Both `show_samples` and `show_samples_rgb` took (indices, preds, images,
labels, count, names), which is six arguments and a mutable default. They now
take a frozen `Samples` holding the last four, which also removed the same
four-value tuple from seven call sites. Reviewing that diff is how I caught
that I had transcribed `real_score = preds[sample][real_id]` as
`samples.labels[sample]` -- a bug I introduced and then fixed before commit.
Other real things, not just rule satisfaction: `np.in1d` is removed in NumPy 2
(NPY201) and is now `np.isin(...).ravel()`; `test_model` computed
correct_indices and incorrect_indices and used neither; two cells grew `img`
inside a loop so it was only bound by the `else` branch; and the Quick, Draw!
downloader now builds a URL whose https scheme is a literal, which is what
S310 was asking for.
The README claimed the .py was "an nbconvert export of that notebook". It is
an export of the CIFAR-10 section only -- 28 of 81 code cells -- and has been
edited since. It says that now, and says the two are separate artifacts rather
than one being regenerable from the other.

kuhy overruled the "do not fix coursework to be better than it was submitted"
rule: git history is the archive, so the working tree can be clean. This lands
the config and the mechanical half of the cleanup -- 9,281 ruff findings under
the fleet config down to 3,686, with no per-file-ignores anywhere.
What is in here:
- pyproject.toml, the first one in this repo. select = ["ALL"], mypy strict,
and the vendored list mirrored into ruff exclude and coverage omit. Five
rules are off and each says why; CPY001 is the only judgement call, because
stamping a copyright header onto 137 university assignments would assert a
licence that was never claimed. No hook is wired up yet -- a gate lands only
once its subject is clean.
- ruff format + the safe fixes, then a second pass over the docstring rules
ruff marks unsafe (they only edit docstring text). 108 files.
- TRAK/sightpy is vendored, not coursework: it is rafael-fuente/Python-Raytracer
(BSD 3-Clause). Verified against a fresh upstream clone with line endings
normalised -- 30 of 32 files byte-identical, ray.py and scene.py carrying a
12- and 13-line local patch that counts rays for the report. 35 files that
should never have been linted, now excluded and restored.
- WDWR, SPD, MOM and ECRYPT are fully clean, by hand and verified by running
them: WDWR's three plot scripts print the same statistics as before, MOM's
PuLP model solves to the same cost. WDWR's graph.py had a 342-character CSV
header embedded as a string literal, which cannot be wrapped -- the data
moved to data/pareto_front.csv. Two 0-byte .py stubs are deleted; an empty
file is not a deliverable and git still has it.
Three harness bugs found by actually running things:
- `run` now forces MPLBACKEND=Agg. TRAK finished its ray trace in 37 seconds
and then sat for 45 minutes: plt.show() had opened an image viewer and was
waiting for someone to close the window.
- TRAK's main.py only pops that viewer with --show now, and its runner writes
to a gitignored build/ via the new --entry-args. The default output path is
outputs/output.png, which is TRACKED -- a plain run overwrote a submitted
deliverable.
- course_lib.sh was 357 lines, over this repo's own cap. Split into
course_probe.sh and course_run.sh.
Verified: ECOTE 26 tests pass, ECRYPT_PROJECT 99 pass, TRAK renders
cornell_box in 37s and exits 0, every module compiles, and every import ruff
removed was checked to be genuinely unused.
