Description

This log:

no parent found for <ome_zarr.reader.Label object at 0x2a2c3d5a0>: None

which appears when reading labels from Zarr should have been disabled by the code in io_zarr.py, but somehow these logs still appear. It is confusing from the users because it seems that there is a problem when it's actually all ok. We should re-disable it.

Research direction

Start in io_zarr.py and trace the label-reading path for Zarr data, focusing on where the 'no parent found' log is emitted or suppressed. Reproduce reading labels from Zarr and confirm that the confusing log no longer appears while otherwise-valid reads continue to work.
