+# Explicit setuptools metadata so editable installs work deterministically
+# regardless of setuptools version and previous install state in the venv.
+#
+# Without this, modern setuptools (>=68) auto-discovery sees the top-level
+# `packages/` directory (Dockerfiles, no __init__.py) as a namespace
+# candidate and falls through to "strict" PEP 660 editable mode, which
+# creates a custom finder. If the venv previously had ryzers installed
+# non-editable (`pip install .`) and is then switched to editable
+# (`pip uninstall ryzers && pip install -e .`), the strict finder shadows
+# the source-tree __init__.py and `from . import RYZERS_DEFAULT_RUN_FLAGS`
+# fails with `ImportError: cannot import name 'RYZERS_DEFAULT_RUN_FLAGS'
+# from 'ryzers' (unknown location)`.
+#
+# Pinning `[tool.setuptools] packages = ["ryzers"]` keeps setuptools out of
+# auto-discovery so the editable wheel is built in compat mode and the
+# regular source-tree __init__.py loads in both fresh and reused venvs.
