#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:14622

#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/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
