Technical summary

PDM uv backend resolution loses index credentials when building the uv command line.

Thread PDM index credentials, including keyring-provided credentials, into the uv resolver invocation while redacting secrets from logs.

The relevant code path points at uv.py, resolver index_url, credentials, and keyring, so the patch should sit where PDM translates configured sources into uv CLI arguments.

The patched code passes PDM's credential-bearing source URL exactly where PDM translates configured sources into uv CLI arguments, so uv receives the authenticated index URL.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import pdm; print('smoke test OK')"
