I’ll re-check the live board state and fix the current routing problems from the source of truth: first delete dangling traces, then clear floating copper, then reroute remaining airwires and re-review until clean.
I started the live cleanup pass, but execution stopped because credits ran out before I could run the review and fixes. No new routing changes were completed in this last pass.
Current remaining work:
Re-run live DRC for airwires, floating copper, and dangling traces.
Delete all reported dangling trace fragments first.
Remove or reconnect floating copper islands.
Re-run routing for the remaining airwires.
Run final DRC/ERC review until there are no routing-related errors left.
Add credits, then rerun this cleanup request so I can finish the PCB routing validation.
