    A.6.8:4.8 — Change‑class lexicon (service‑specific narrations)

    Preface node heading:a-6-8-4-8-change-class-lexicon-service-specific-narrations:17080

    What this page is

    This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

    Methodology

    Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

    Content

    When the draft describes “service changes”, narrate changes using stable change classes (A.6.P), specialized to the serviceSituation lens:

    • declareRelation(serviceSituation(…)) (introduce the bundle)
    • withdrawRelation(serviceSituation@ed=k) (retire the bundle)
    • retargetParticipant(accessPointRef := …) (move the access point / endpoint host)
    • retargetParticipant(deliverySystemRef := …) (change the realizing delivery system; e.g., re‑platforming)
    • retargetParticipant(providerAssignmentRef := …) (change provider role‑enactor; outsourcing / org change)
    • reviseByValue(accessSpecRef := …) (edit interface description content)
    • reviseByValue(deliveryMethodRef := …) (edit runbook, workflow, or procedure)
    • reviseByValue(promiseContentRef := …) (edit promise content; typically new edition)
    • changeRelationKind is not applicable here unless splitting the family (rare)
    • rescope, retime(Γ_time), refreshWitnesses(witnesses := …) as required
