Python tests

python tests_py/run_all.py            # everything
python tests_py/run_all.py gguf key   # only files matching those words
python tests_py/test_linter.py        # one file directly

Exits non-zero if anything fails, so it works as a CI entry point.

No third-party dependencies. test_api.py needs a running server (python app.py) and the requests package the LM Studio provider already uses; it prints SKIP and passes when the server is down, so the rest stay useful offline.

File Covers
test_answer_values.py The answer keys themselves, recomputed from scratch
test_answer_key.py The correctness grader, both directions
test_api.py Suites API, read-only guards, run selection
test_code_lint.py Static code rules, and the false positives they must not repeat
test_collision.py Qualified question IDs
test_gguf.py GGUF header parsing and model classification
test_linter.py Report rendering
test_lmstudio.py LM Studio model listing, against stubbed HTTP
test_reporting.py Report naming and the per-suite breakdown

The UI tests live separately, under web/src/**/*.test.tsx — run them with cd web && npm test.

Why these are scripts rather than unittest cases

They exercise a diagnostic tool, so the output is read as much as the exit code. test_code_lint.py is a table of which rules fire on which input, and that is worth more when debugging a false positive than a row of dots. run_all.py aggregates exit codes for the times you only want a verdict.

Each file runs in its own process. Several load plugins directly, which would otherwise collide in sys.modules.

test_answer_values.py is the one to keep honest

The other files test code. This one tests data — it recomputes every numeric answer key with exact arithmetic and brute-force search, then asserts the shipped answers.json agrees.

That matters because a wrong key fails correct work with total confidence, which is the exact failure the answer-key grader exists to remove. It earned its place immediately: the Winograd referent had been recorded backwards, and shipping it would have marked every correct answer wrong.

If you add or edit a key, add the computation here too. A key nobody can re-derive is a liability.
