- Move cloudpickle from required to optional-dependencies[orchestration] - Add lint check in lint.yml to enforce no required dependencies - Update build-wheels.yml comment explaining --no-index as lint - Bump Node SDK version to 0.2.7 The BoxRuntime orchestration feature requires cloudpickle for serializing Python closures into VMs. Most users don't need this, so it's now opt-in via: pip install boxlite[orchestration] Fixes wheel build failure where --no-index couldn't resolve cloudpickle.

Summary
[orchestration]extra--no-indexcomment in build-wheels.yml to document its lint purposeProblem
The wheel test job was failing with:
The
--no-indexflag prevents PyPI access, but cloudpickle wasn't in the wheelhouse.Solution
cloudpickle is only used by
BoxRuntime(multi-box orchestration), which is already wrapped intry/except ImportError. Making it optional aligns the dependency declaration with the existing code pattern.Before:
pip install boxlite # Requires cloudpickleAfter:
Test plan
python -c "import boxlite"works without cloudpickle installedpip install boxlite[orchestration]+from boxlite import BoxRuntimeworks
