Pandas recommendations for Xarray #7183

This is not a setup error. The PD rules come from pandas-vet and are largely syntax/name based; Ruff does not infer that the receiver is an Xarray object before flagging methods/properties that look like the pandas patterns.

If the project uses Xarray heavily, the practical fix is to disable the offending PDxxx rule globally or with a per-file ignore, for example:

[tool.ruff.lint.per-file-ignores]
"src/xarray_code/**/*.py" = ["PD011"]

For isolated cases, use # noqa: PD011 on the line. Prefer the specific code rather than ignoring all PD rules, since some pandas-vet checks may still be useful elsewhere. Without type-aware analysis, Ruff cannot reliably distinguish DataArray.values from DataFrame.values at that call site.
