This is a great quality feature for physical design triage. Parsing the raw report_drc output robustly is definitely majority of the task here.

I'm actually already mapping out the parsing logic for report_drc as part of the integration testing suite that i have proposed for the summer (to extract violation counts for CI baseline assertions). Structuring that parser so it outputs a standardized JSON schema could serve both the CI testing gates and this new categorizer tool perfectly. It would be a great architectural win to share that parsing layer. i would be happy to align on the data schema for the parsed output whenever this gets picked up!
