Search and filter pending excavation permit cases. Use this to find permits by street, city, applicant, project type, permit verdict, or risk level. Returns a summary of each match, not the full utility line detail — call get_permit for that.

Retrieve the complete review for one permit case: every utility line near the excavation, its owner, distance, ASCE 38-02 data quality grade, provenance, and crossing risk, plus the overall verdict and which lines need field verification before sign-off.

Scan the whole permit portfolio for individual utility lines that are dangerous to dig near: close to the excavation, poorly evidenced, or where the county record and the independent detection disagree. This is the cross-portfolio triage question — 'what is about to hurt someone' — rather than a per-permit lookup. Results are ranked by consequence-weighted risk.

Roll up the whole permit portfolio: how many cases sit at each verdict, where the risk is concentrated by city and project type, overall record corroboration, and how much unverified consequence exposure is outstanding. Use this for 'how are we doing' questions rather than per-permit ones.

Produce a prioritised potholing plan: which specific lines should be physically exposed before excavation, in what order, and why. Ranks by consequence-weighted risk so a limited field budget is spent where a strike would cost the most. Call with a permit_id for one case, or with no arguments for a portfolio-wide plan.
