Need at least one point

Error message

Need at least one point

What it means

hyperbolicCentroid() was called with an empty points array. A Fréchet mean over zero points is undefined, so the function refuses immediately rather than entering the iterative optimization with no data.

Solutions

1. Pass at least one point to the operation.
2. Guard the call site so empty batches are skipped instead of submitted.
