  "legalScope": "Bounded Maryland PSC pipeline-safety rules in COMAR 20.55-20.57.",
  "applicabilityCaveat": "Maryland PSC enforcement under PHMSA certification is limited to intrastate gas and hazardous-liquid pipeline operators and applicable LPG systems. PHMSA retains inspection and enforcement responsibility for interstate gas and hazardous-liquid pipelines. Coverage also depends on operator class, gas-company or master-meter status, facility and commodity definitions, exemptions, waivers, and federal preemption.",
  "incorporationCaveat": "Maryland provisions use both fixed editions of private or federal guidance and prospective phrases such as 'as amended' for federal statutes and 49 CFR. This connector preserves the consolidated Maryland text retrieved on the stated date but does not infer that every later federal amendment is incorporated for every legal purpose. Verify the controlling Maryland incorporation rule, federal edition, and event date.",
  "publicationCaveat": "The Library of Maryland Regulations is the official consolidated access system, but the Maryland Register and filed rulemaking record control adoption history. Administrative-history notes are evidence aids, not substitutes for the promulgation record. The PSC program description is dated September 2011 and is used only to corroborate program scope, not current rule text.",
  "rightsCaveat": "Official Maryland and federal legal-source captures are preserved with attribution and hashes. State presentation, seals, site software, and incorporated private standards may carry separate rights; incorporated standards are referenced but not reproduced by this connector.",
