csview: evaluator compatibility issues resolved — unchanged submission reaches official SOLVED (✅ 335 tests)

Update: we have now completed an end-to-end reproduction and isolated the evaluator-side causes affecting `wfxr__csview.8ac4de0`.

Using the same stabilized submission that previously produced an official score of 69, we identified and corrected two independent evaluator compatibility issues:

1. A test-environment dependency interaction caused one branch to fail before producing `results.xml`. The branch `run.sh` upgraded pytest at runtime, which produced an incompatibility with the installed `libtmux` pytest plugin. Preventing that unintended pytest upgrade restored normal branch execution.

2. JUnit testcase names produced under the evaluator's `eval.tests.*` namespace were compared literally against the corresponding `tests.*` names in `tests.json`. This caused valid executed tests to be simultaneously classified as unexpected and injected as `not_run`. We added namespace-aware matching while preserving the existing completeness checks.

We also retained the existing `pytest-timeout` compatibility handling (`thread` → `signal`) already required to prevent xdist worker loss on timed-out tests.

Verification sequence:

* isolated failing branch reproduced;
* minimal evaluator-side correction applied;
* isolated branch: 2/2 passed, no branch errors or warnings;
* evaluator regression suite: 41/41 passed;
* complete ProgramBench official evaluator rerun performed.

Final official result:

`wfxr__csview.8ac4de0 ✅ 335 tests`
`Average 100`

The resulting machine-readable evaluation artifact contains:

* `solution_branch: submission`
* `error_code: None`
* `error_details: None`
* 348 recorded test results
* 347 passed
* 1 skipped
* 0 `not_run`
* no branch errors
* no warnings

Most importantly, the submission archive was unchanged between the earlier score-69 run and the final solved run.

Submission SHA-256:

`a7b055b8dea5dddfadf88d381f634cdf2af3f6ac02b62f024740dd12b3bc512f`

Final official `eval.json` SHA-256:

`930daeeb3c4f080a98414b84338e2a6506f64e6e0ef3ab158d77be252a63d2d2`

ProgramBench repository HEAD used for the final run:

`963063c9271cc40fa179977356782ea4582e0b0c`

We preserved the complete evidence package: original submission, final `eval.json`, precheck reports, reconstruction state, evaluator state, evaluator diff, regression evidence, provenance, manifest, and SHA-256 inventory. The package was independently hash-verified after transfer from the Linux evaluation environment to Windows.

We would be happy to provide the evaluator patch and/or the verification package privately to the ProgramBench maintainers for independent reproduction.

Could you advise the preferred way to submit this result and evaluator finding for official independent verification?

Inizia esaminando il comportamento dell’evaluator descritto in relazione al branch run.sh, alla compatibilità pytest/libtmux, a tests.json e alla corrispondenza dei testcase con eval.tests.*. Esegui la suite di regressione dell’evaluator 41-test indicata e ispeziona l’eval.json finale; il lavoro è completato quando riproduci i risultati relativi alla compatibilità e verifichi in modo indipendente il risultato 335-test riportato, senza modificare la submission.
