I’ll locate the floating copper island named “Via-Island-0”, remove or reconnect that orphaned copper, then re-run the Floating Copper review to verify it is cleared.

The floating island belonged to generated GND copper, so I’m restoring the affected GND routing now and then I’ll re-check the DRC.

Processing was stopped.

Here's a summary of what I was working on:
Considering net routing changes

I'm thinking about whether I should remove net routing by net UID. I need to check if the designator uses the net UID prefix. It might be a good idea to rewrite layout nodes to delete net routing for specific net UIDs, like ["3c..."]. I want to make sure I'm making the right adjustments, so I'll carefully consider how those changes will impact the overall design and functionality.
