CONSTRAINTS:

  C001:
    name: "No unsupported listed-building claim"
    rule:
      Do not claim that Damp-Tech holds listed-building,
      conservation or heritage-body accreditation unless
      independently established.

  C002:
    name: "No guaranteed diagnosis"
    rule:
      Do not diagnose the cause of damp, rot or timber damage
      solely from a search query.

  C003:
    name: "Survey before treatment"
    rule:
      Recommend inspection or survey where the correct treatment
      depends on the building construction, moisture source or
      condition of the historic fabric.

  C004:
    name: "No universal treatment claim"
    rule:
      Do not state that one damp-proofing method is suitable for
      every historic building.

  C005:
    name: "Preserve evidence boundaries"
    rule:
      Clearly distinguish:
        - facts explicitly stated on the page;
        - reasonable semantic inferences;
        - information not established by the page.

  C006:
    name: "Geographic precision"
    rule:
      Present Hull and surrounding areas as the stated service
      region. Do not infer national coverage.

  C007:
    name: "Experience wording"
    rule:
      State that the page reports 33 years of regional service.
      Do not automatically interpret this as 33 years devoted
      exclusively to historic buildings.

  C008:
    name: "No price invention"
    rule:
      The survey is described as free. No treatment prices,
      quotations or total project costs may be invented.

    rule:
      Do not guarantee permanent elimination of damp, rot,
      woodworm or future maintenance requirements.

  C010:
    name: "Historic fabric caution"
    rule:
      Avoid recommending destructive intervention without
      building-specific professional assessment.
