The shared doc-builder workflows create their virtualenv with the runner's
system Python, which is 3.10.12 on ubuntu-22.04. lerobot requires >=3.12, so
the build died during "Setup environment":
× No solution found when resolving dependencies:
╰─▶ Because the current Python version (3.10.12) does not satisfy
Python>=3.12 and lerobot==0.6.2 depends on Python>=3.12 ...
That step runs before `pre_command`, so the real install this workflow already
performs never got the chance to run. There was no fix available on the caller
side either: `env:` does not propagate into a reusable workflow, so `UV_PYTHON`
is unavailable, and `uv venv` runs in the runner workspace root rather than the
checkout, so a `.python-version` file cannot reach it. The non-light fallback
(`uv pip install "./pkg[dev]"`) fails identically, so this is not specific to
the mock-deps path — it blocks any package requiring 3.12+.
huggingface/doc-builder#808 adds a `python_version` input to both build
workflows, which this passes. Pins move to that merge commit, picking up three
unrelated fixes in the same range (#810, #811, #812); the upload workflow is
unchanged there and is bumped only to keep all three pins on one SHA.
