# Carrier-State Coverage Matrix This matrix is the working inventory for source completeness across carriers and states. Primary data file: - `/Users/petedunn/Library/CloudStorage/Dropbox/Mac/Downloads/Masters telecom/POTS Shutdown Notice app/backend/app/pots_shutdown_tracker/data/source_coverage_matrix.json` How to use it: - `connector_status` tracks whether discovery is wired for the official source family. - `parse_status` tracks whether the source family is parsed cleanly into notice records. - `geography_status` tracks the strongest geography we can derive from that family. - `search_visibility` tracks whether the source family is represented in area coverage and area-risk workflows. Admin report: - `GET /api/pots-shutdown/admin/source-coverage-report` The report combines the planned matrix with live corpus metrics: - live raw document counts - live notices by carrier and state - analog-relevant versus analog-possible notice counts - active notice counts - unique CLLI counts - unique wire-center counts - notice-location row counts - impacted-address row counts - structured-state versus parsed-state-fallback usage This is the baseline artifact for closing source gaps carrier by carrier before Neon and Hugging Face rollout.
