All 50 states plus DC are represented, not legally cleared. No complete 50-state operator-license, 811 notice-period or Tier 4 applicability chart is claimed. Unknown is not No. A reference page is not a permit, route clearance, training certificate or authorization to dig.
44 jurisdictions have a selected dig-rule summary or official resource pointer; the others remain explicit gaps. 27 substantive public permit references were readable. Neither count establishes completed legal coverage.
All FHWA-listed permit destinations were attempted; current public DOT replacements are shown only when substantive material was readable. Login-only portals, shells and blocked sources were not treated as reviewed law. Federal employer standards are edition-labeled references, not proof of a particular job's coverage.
