What changed

tools/eval/github_tasks.py gets 1 more verified GitHub task, for 5 in all. That's far short of the 20 Zach wants. I stopped at the turn budget and kept the bar where it was.

Task	Repo (license)	Upstream release (PyPI date)	upstream_change
gh-pip-tools-flag-default	pypa/pip-tools (BSD-3-Clause)	click 8.5.0, 2026-08-26	click-8.5-flag-default-unset

• Pairs: 0. The new key has one task. Neither sibling I found qualified (see the rejected candidates).
• Timing:
  • The upstream change, Streamline option flag management pallets/click#3641, merged 2026-07-16, after the June 2026 cutoff.
  • Issue get_compile_command emits --no-index unconditionally with click 8.5.0 pypa/pip-tools#2472 was opened 2026-09-02. Its fix, #2475, merged 2026-09-18.
• Merge commit: base_commit is the merge's first parent, c58d5d9.
• Setup: env SETUPTOOLS_SCM_PRETEND_VERSION=7.6.1 uv pip install --exclude-newer=... -e .[testing]. The archive has no .git, so setuptools-scm needs a pretend version.
• Test command: -n0, because the project's addopts turn on xdist.
• Install: about 29 MB.
• Fix: it changes code. get_compile_command now compares a value with option.get_default(...). The fix also adds a click compat module for LazyFile.

Base failing output (containerized, -v)

• Test: tests/test_utils.py::test_get_compile_command_no_index_not_added_by_default.
• Click 8.5.0, at the base: fails.

  E           AssertionError: assert 'pip-compile ...quirements.in' == 'pip-compile requirements.in'
  E             - pip-compile requirements.in
  E             + pip-compile --no-index requirements.in
  

  The output also has LazyFile/safecall DeprecationWarnings. They are warnings only.
• Click 8.5.0, at the fix: passes.
• Click 8.4.2, at the base: passes.
• check ran through a helper that calls repos.materialize, prepare and run_tests with container.run, the same steps agent_eval.py check runs. Containers ran one at a time, none were left behind, and --on-host was never used.

Cause-word checks

• Cause words: sentinel, default is unset, default is now unset, default stays unset, `unset and 8.5. They name the mechanism: since click 8.5, Option.default stays the UNSET sentinel.
  • Bare unset is left out (review fix). It is ordinary English, and a fix that only treats the symptom says it ("skip options left unset").
  • `unset has a leading backtick, so it matches UNSET written as code.
• Neither "unset" nor "sentinel" appears in the base piptools/utils.py or piptools/scripts/compile.py (grepped at c58d5d9).
• I checked them with grading v2's mentions (word start, lowercase) against:
  • the whole captured base output;
  • the whole laid-over tests/test_utils.py at the fix sha (828 lines);
  • the symptom words, in both directions;
  • the names get_compile_command and the test's name;
  • the words a symptom-only fix would use.
• No hits.
• All but 8.5 are non-version words. 8.5 is one under is_version_word, so it is added to the expected set in test_the_cause_words_grader_v2_skips_are_exactly_the_versions. Added version words: 8.5.
• Leak review of the laid-over file:
  • The new test's docstring states only the symptom ("--no-index must not show up in the recorded command unless it was actually passed. See GH-2472.").
  • It does point at the issue, which states the cause. The record's comment says so, and notes that eval sessions have no web tools.
  • No other comment, docstring or test name mentions click versions, defaults or sentinels.

Rejected candidates (this batch, both runs)

• [CLI] Fix argument help rendering with click 8.5 huggingface/huggingface_hub#4759 (click 8.5 Argument gained help): the laid-over test's comment states the cause ("Click >= 8.5 renders its own 'Positional arguments' section").
• fix(swarm_session): close HTTP error responses; read a flag's default through Click st0w/sbx-omnigent-launcher#118 (click 8.5 flag default, sibling): the click part changes only a test, and its comment states the cause.
• Show real defaults on the CLI page instead of Sentinel.UNSET mkdocs-ng/mkdocs#140 (Sentinel.UNSET defaults): a click 8.3 change, before the cutoff. The fix is in docs/hooks.py.
• Fix click help rendering for resolver options cthoyt/class-resolver#123 (get_metavar(ctx)): a click 8.2 change, before the cutoff.
• --help shows no description for any positional argument when click 8.5.0 is installed MakazhanAlpamys/Soup#1790 (click 8.5 Argument help via Typer): no fix PR for it changes code and tests together.
• fix: support Click 8.5.0 sqlfluff/sqlfluff#8648 (click 8.5): the fix is only a pin.
• build: support Pillow 13 thumbor/thumbor#1943 (Pillow 13 refuses to write mode I as PNG): the new test's name, test_read_should_clip_32bit_grayscale_to_16bit_png, states the fix.
• Support duckdb 2.0 theislab/ehrdata#333 (duckdb 2.0, an open result owns the connection): the laid-over test's only change is fetchone()[0] → fetchall()[0][0], the fix itself.
• fix: the warehouse reads a scalar's whole result, so DuckDB 2.0 runs the next query PedroLFerraz/ankigen#55 (same duckdb change): the test docstring states the cause; fastembed's ONNX install is large.
• fix(duckdb): refuse a no-result query on DuckDB 2.0 before it runs Veridelta/veridelta#438 (duckdb 2.0 SET result): the test docstrings state the cause.
• fix(duckdb): DuckDB 2.0-compatible result APIs (stage 1) ccgsem/casmsocial#29, tensor-server: support DuckDB 2.0; require duckdb >= 1.5 biopb/biopb#1434 (duckdb 2.0 result APIs, arrow lambdas): the test changes are the fix. Both changes were deprecated before the cutoff.
• fix: require duckdb 2.0 and make the DuckDB accelerator robust MPoppinga/PartitionCache#44: the accelerator fixes aren't caused by duckdb 2.0, and the tests mock duckdb.
• fix: support DuckDB 2.0 in joins, time zone lookup and from_native typing narwhals-dev/narwhals#4099 (duckdb 2.0 multi-part ColumnExpression in joins): the join tests that fail at the base aren't changed by the fix. The changed tests are sql_query() text expectations and typing tests.
• DuckDB 2.0: toArrow calls removed connection methods, and lambda functions emit the deprecated syntax eakmanrq/sqlframe#654 (duckdb 2.0): fetch_arrow_table and the arrow lambda were deprecated before the cutoff, and the errors name their fix.
• fix(deps): import MISSING from pydantic_core to support both pydantic 2.13 and 2.14 Danipulok/pydantic-jsonschema#157 (pydantic 2.14 MISSING moved): the deprecation warning names its fix.
• fix(api): stop the backup export from downloading empty under Starlette 1.9 LiriothTeltanion/IvritSheli#87 (Starlette 1.9 FileResponse and disconnect): the test docstring states the cause.
• fix(auth): device-scope ceiling holds on encoded ?/# paths under Starlette 1.9 (#4367) protoLabsAI/protoAgent#4372 (Starlette 1.9 path encoding): a large AI-agent repo, and the cause is stated in the source comments.
• fix: import on SQLAlchemy 2.1, which removed FallbackAsyncAdaptedQueuePool bedrock-python/sqlalchemy-foundation-kit#79, Fix/sqlalchemy 2.1 gledi-ai/aiotrino#12 (SQLAlchemy 2.1): not pursued, because 2.1's changes were documented in its betas and "What's New in 2.1", likely before the cutoff.
• BUG: support python-dateutil 3.0 tzfile (GH#71459) pandas-dev/pandas#71495 (python-dateutil 3.0 tzfile): pandas needs a compiled build and is a 413 MB repo. Most dateutil 3/4 downstream PRs are pins, because botocore caps it below 3.
• Candidates from PRs MIT-618: three verified GitHub tasks (first batch, partial) #164 and MIT-618: one more verified GitHub task (second batch) #165 were not re-checked.

Why

Ticket: MIT-618 (third batch), the GitHub-task eval. These are real post-cutoff tasks for the arms run.

How it was tested

• Containerized before/after/previous-version runs for the new task, as described above.
• server/tests/test_eval_repos.py and test_eval_grader.py pass after merging origin/feature/eval-setup (grading v2).
• make check passes.

Learned

• uv pip install of a project versioned by setuptools-scm fails from a git archive tree (no .git). Prefix the setup with env SETUPTOOLS_SCM_PRETEND_VERSION=<version>; shlex.split keeps it one command.
• Projects whose addopts turn on xdist (--numprocesses=auto) need -n0 in the test command. -p no:xdist makes pytest reject the addopts.
• duckdb 2.0 (2026-10-21) has many downstream fixes, but most laid-over tests contain the fix (fetchall(), con.sql) or a docstring stating the cause. Its novel changes (an open result owns the connection, a plain string in an expression is a value) are the ones worth mining.
• python-dateutil 3.0 (2026-10-21) and 4.0 (2026-11-01) are new, but few downstream projects have upgraded yet, because botocore caps dateutil below 3.
• GitHub search with several bare words (dateutil fold gap) returns noise. Quoted phrases plus in:title work better, and issue search finds reporter analyses that point at the fix PR.
• Worktree isolation refuses for loops over gh and sleep-then-read. Put loops in a .scratch/ helper and use background runs.
