EXECUTION_GUARANTEE {

    THIS_FLOW guarantees_that:

        1. The business, service and intended page location are explicitly
           represented as canonical entities.

        2. Restoration outcomes are expressed conditionally rather than as
           guarantees.

        3. Inspection and floor condition remain prerequisites for selecting
           an appropriate restoration method.

        4. General customer comments are not falsely converted into proof of
           Darlington wood floor restoration work.

        5. Example finish types are not represented as confirmed products
           without provider verification.

        6. The conflict between the Darlington page identity and repeated
           Darlington body references is preserved and disclosed.

        7. AI-generated answers are recursively checked against facts,
           exclusions, locality integrity and confidence thresholds.

        8. Unsupported prices, accreditations, warranties, project histories
           or guaranteed outcomes cannot be generated from this specification.
