crd2pulumi v1.6.1 _utilities import bug repro

Minimal repro for a platform-dependent bug in pulumi/crd2pulumi v1.6.1: generated intermediate sub-package __init__.py files use from . import _utilities, but _utilities.py is only emitted at the top-level SDK package. Importing any leaf module fails with:

ImportError: cannot import name '_utilities' from 'pulumi_widgets.example'

Run

go install github.com/pulumi/crd2pulumi@v1.6.1
export PATH="$HOME/go/bin:$PATH"
git clone https://github.com/wlami/crd2pulumi-utilities-repro
cd crd2pulumi-utilities-repro
bash repro.sh

Same crd2pulumi v1.6.1 source, identical mod hash, identical pulumi codegen deps (pulumi/pkg/v3 v3.216.0, pulumi-kubernetes/provider/v4 v4.0.0-20260115033456-f47bc2d6f199). Generated relative-import depth differs by one level between platforms. Output is deterministic per platform across multiple runs.

What the bug looks like

Generated layout (Linux):

out/pulumi_widgets/
|- __init__.py            from . import _utilities    OK (top-level)
|- _utilities.py          <- only copy in the tree
|- example/
|  |- __init__.py         from . import _utilities    BROKEN
|  \- v1/
|     \- __init__.py      from .. import _utilities   OK
\- meta/
   |- __init__.py         from . import _utilities    BROKEN
   \- v1/
      \- __init__.py      from .. import _utilities   OK

On macOS the same generation produces from .. import _utilities at the depth-1 sub-packages and from ... import _utilities at depth-2, which works at runtime.

Workaround (Linux)

Rewrite the depth-1 sub-package imports after generation:

find <sdk-root> -mindepth 3 -name __init__.py \
  -exec sed -i 's|^from \. import _utilities$|from .. import _utilities|' {} +

-mindepth 3 from <sdk-root> skips the top-level package __init__.py (which must keep from . import _utilities) and targets only the intermediate sub-package files.
