Contractor-to-permit specialty match

match_contractor_to_permit

Read-onlyIdempotent

Cross-reference a WA contractor's L&I license specialty against a permit's required specialties. Returns whether the contractor is qualified to pull/work the permit, with explicit gap callouts (e.g. "missing electrical specialty 02"). Combines real-time L&I data with Kolmo's authoritative permit catalog.
