What changed

This PR is the cleanup commit in tools/eval/github_tasks.py. It adds 0 new GitHub tasks, so the file still holds 9. Zach wants 20. Batch 9 covered developer tooling and packaging. I hit the turn budget with no candidate that met the bar; see the rejected candidates.

The cleanup

• gh-pydantic-settings-validate-by-name:
  • Dropped the cause words leaves model_config, model_config unchanged and the bare no longer mutates. Kept no longer mutates model_config.
  • The comment now says "every phrase but the version carries its object". That makes it true: every remaining phrase names model_config or validate_by_name, and the only exception is 2.14.
  • Two comment lines were re-wrapped to stay under the line limit.
• gh-table-extraction-bool-form: the comment no longer says the laid-over test names "say" "boolean form field". The names use underscores, so grading can't match them. The reason given now is that a fix treating only the symptom says it ("parse the boolean form field and apply its default").

No other line in the file changed.

New tasks

None. Pairs: 0. New version words: none. The expected set in test_the_cause_words_grader_v2_skips_are_exactly_the_versions is unchanged.

Rejected candidates (this batch)

• pip 26.2 : cannot import name "stdlib_pkgs" from "pip._internal.utils.compat" pypa/pip-tools#2436 / #2437, fix #2438 (pip 26.2, 2026-07-29). The upstream changes are pip#14206 (allow_editables on the preparer, merged 2026-07-27) and pip#14133 (stdlib_pkgs moved, merged 2026-07-02). This was the closest miss:
  • Offline in the container, on pip 26.2, the backtracking test_cli_compile.py tests fail at the base with TypeError: RequirementCommand.make_requirement_preparer() missing 1 required keyword-only argument: 'allow_editables' and pass at the fix.
  • But none of those tests is added or changed by the fix. The fix's changed tests either need the network or fail on any pip:
    • test_compile_with_generate_hashes_preserves_extra_index_url and test_name_collision need the network: the minimal_wheels_path fixture and build deps download setuptools.
    • the new test_package_finder test imports the fix's new helper, so it fails at the base on any pip.
  • The error also names the missing argument.
• packaging 26.3 breaks disabling of source-package constraints (Requirement() now rejects trailing newline) mxstack/mxdev#100 (packaging 26.3, packaging#1345 merged 2026-07-21): the laid-over test's docstring states the cause and the fix ("packaging >= 26.3 rejects requirement strings with trailing whitespace, so process_line must strip before parsing").
• packaging 26.3+ does not work with bsb-core dbbs-lab/bsb#254 (packaging 26.3 slotted Requirement): the new tests' comments state the cause (pickling through str(self)). The fix's own comments attribute the change to packaging 25 and 26.2, not 26.3.
• Packaging 26.2 breaks DependencyVersion deepcopy and dependency resolution posit-dev/images-shared#721 (packaging 26.2 deepcopy): packaging 26.2 came out 2026-04-24, before the cutoff.
• upstream: packaging restricting grammar pdm-project/pdm#3993 (packaging's stricter marker grammar, packaging#1440): not in any packaging release yet.
• virtualenv 21.15.2 breaks four tox tests tox-dev/tox#4347 (virtualenv 21.15.2): the fix's only src/ change is a comment, so in effect it changes only tests.
• fails in python 3.14.7 and hatchling 1.32.3 jupyterlab/hatch-jupyter-builder#147 (hatchling 1.32.3 generic BuildHookInterface): the fix's only test change is a module-level skip. The TypeError from subscripting names its fix.
• Incompatible with hatchling 1.32.3 llimeht/hatch-sphinx#5 (same hatchling change): the fix PR docs(decisions): propose cq knowledge unit field mapping #6 isn't merged.
• [BUG] Same-page references render with empty link destinations liran-funaro/sphinx-markdown-builder#78 (Sphinx 9.1.1): the bug isn't tied to a Sphinx change. The issue names none, and the fix is a missing branch in the translator.
• numpy.typing.NDArray (PEP 695 type alias) is linked as py:class, but its inventory entry is py:data tox-dev/sphinx-autodoc-typehints#1104: the cause is NumPy 2.5's PEP 695 NDArray (2026-06-21, before the cutoff, and scientific).
• [Bug]: Fromager / tomlkit fail to parse valid TOML python-wheel-build/fromager#1356 (tomlkit 0.15.1 parse error): the test comment states the fix ("tomlkit rejects this, stdlib tomllib accepts it"). Nothing shows it is a 0.15.1 regression.
• config-package strips the zope.meta header comment from pyproject.toml zopefoundation/meta#440 (tomlkit 0.15.1 drops a header comment under sort_keys): the fix changes no test.
• beartype 0.23's intentional is_subhint(Any, T) == True breaks plum's method-redefinition detection, silently deleting registered methods beartype/plum#295 (beartype 0.23 is_subhint(Any, T)): not pursued. The issue (2026-08-11) and fix (2026-09-03) came after 0.23.0rc0 (2026-08-08) but before 0.23.0 final (2026-10-10).
• Candidates from PRs MIT-618: three verified GitHub tasks (first batch, partial) #164, MIT-618: one more verified GitHub task (second batch) #165 and MIT-618: one more verified GitHub task (third batch) #167–MIT-618: add the table-extraction-pro FastAPI 0.147 GitHub task (batch 8) #171 were not re-checked.

Why

This is the batch-9 slice of MIT-618, the GitHub-task eval. The cleanup makes two task records' notes match the cause-word rules the reviews settled on.

How it was tested

• server/tests/test_eval_grader.py and server/tests/test_eval_repos.py pass, 109 tests.
• make check passes after git merge origin/feature/eval-setup, which was already up to date.
• pip-tools candidate runs: the containerized steps that agent_eval.py check runs, through a .scratch/ helper calling repos.materialize, repos.prepare and repos.run_tests with container.run. Containers ran one at a time, none were left behind, and --on-host was never used.

Learned

• Developer-tooling releases after the cutoff, for future mining:
  • setuptools 83.0.0 (2026-07-04), 84.0.0 (2026-08-08), 84.1/84.2 (2026-10-19)
  • hatchling 1.31.0 (07-08), 1.32.0 (08-11), 1.32.3 (09-17), 1.33.0 (10-28)
  • packaging 26.3 (08-04)
  • pip 26.2 (07-29), 26.3 (about 11-02)
  • Sphinx 9.1.1 (10-20), 9.2.0 (10-21)
  • griffe 2.2.0 to 2.4.1 (08-16 to 10-22)
  • tomlkit 0.15.1 (07-17), 0.15.2 (10-16)
  • coverage 7.15 to 7.17 (07-02 to 11-04)
  • build 1.6.0 (08-27)
  • twine 7.0.0 (07-28)
  • typeguard 4.6.0 (07-26)
  • pre-commit 4.6.1 to 4.7.0 (07-21 to 10-13)
  • beartype 0.23.0 (10-10, rc0 08-08)
  • typing_extensions 4.16.0 (07-02, rc 06-24)
• Tooling fixes in this area are often test-only adaptations (tox), compat shims with no test (zope meta), or regression tests whose docstrings state the cause (mxdev, bsb). The yield is low, lower than for runtime libraries.
• pip-tools' pip_conf, pip_with_index_conf and minimal_wheels_path fixtures download setuptools from PyPI at session start, so any test that uses them fails under --network none. Plain runner compile tests with --no-index run offline.
• GitHub issue search tokenizes dotted versions: "hatchling 1.32" in:title finds nothing, while "hatchling 1.32.3" in:title,body finds the issues. Search the full patch version, and search bodies too.
• The worktree guard refuses shell loops over gh with a loop variable. Put repeated gh api calls in a .scratch/ helper run with python3 -I.
