what a new run launched now would send

autodoc: empty __all__ attribute is ignored
**Describe the bug**
autodoc: empty `__all__` attribute is ignored

**To Reproduce**
```
# example.py
__all__ = []


def foo():
    "docstring"


def bar():
    "docstring"


def baz():
    "docstring"
```
```
# index.rst
.. automodule:: example
   :members:
```

All foo, bar, and baz are shown.

**Expected behavior**
No entries should be shown because `__all__` is empty.

**Your project**
No

**Screenshots**
No

**Environment info**
- OS: Mac
- Python version: 3.9.1
- Sphinx version: HEAD of 3.x
- Sphinx extensions: sphinx.ext.autodoc
- Extra tools: No

**Additional context**

Work only inside this repository checkout. Make the code change the task
describes, keeping the diff focused — no drive-by refactors.

When you are done, leave your changes committed or in the working tree;
they are collected automatically.

Stay on this snapshot checkout (`task/ycb_sphinx_pr8595`). Never checkout, pull, or rebase onto `main`. That branch is a README-only orphan.
Stay on this HEAD. Do not fetch another default branch. Push only on the Cursor-created `crazy-cursor/…` side branch from this HEAD.

Some past runs of this task were launched with a different prompt (the prompt template changed since, or those runs predate this benchmark's stored prompt). Each run persists the exact prompt it sent at launch — that per-launch record is the audit trail; this page shows only the current one.
