| # 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. | |
