E.11.DSG:4.5 - Return to the Suite collection and exact sources when products change

The Reference identifies the Suite collection; it does not decide or copy which product series belong. Its public return names:

  • the Suite collection and a working route to its identity, inclusion, and removal decisions;
  • each product series that belongs to the Suite, and each edition, result, state, or direct source that changes the answer;
  • when reproducibility needs one, the exact optional configuration description, its as-of scope, and its source return.

A Reference projection states which belongs-to claims it captures, omits, or coarsens and the time or scope for which that account applies. It does not become the authoritative collection account. A combined carrier identifies each constituent and keeps identities, editions, access, currentness, and any separately established maintenance claims distinct. A copied product table or locator without a working source return is orientation only.

When a DPF publishes a new edition, test separately whether that edition belongs to its product series. Then refresh only the Reference advice, availability, compatibility, warning, or source return that changed. A superseded or unavailable edition still belonged to its product series while that series continued. If a product series in the Suite no longer qualifies under the inclusion rule, show the warning and return to E.4:4.2 and E.4.PFAD for repair, removal, Suite change, or retirement. Until that decision, do not present the product as qualifying, current for the defeated common use, or recommended on that basis. Belonging continues until an effective removal only while the same product series and Suite continue; restoration before removal preserves the occurrence, while removal followed by inclusion creates another. If the product series ends or its identity rule identifies another series, belonging to the old Suite ends without a prior removal. The new product series needs a new inclusion.

An absent, unavailable, stale, or unneeded Reference does not erase the Suite, end current belongs-to occurrences, or prohibit direct use of a known DPF result. It does prohibit a claim that the Reference currently supplies the cross-DPF route. If the Reference loses source return, becomes unavailable, or no longer supports its claimed use, present its historical editions, warn readers, and use a direct DPF where the result is already known. Edition identity, publication, availability, and currentness continue to follow their own facts when a maintenance commitment is absent or ends; only the maintained claim then lacks support. If the Suite temporarily contains one product series or none under an explicit preservation decision, present no current cross-DPF answer; return to restoration, review, or retirement. When a Suite end or retirement decision takes effect, every current belongs-to occurrence ends without separate removals. Keep the past fact that each product belonged to that Suite, but require another constitution decision and new inclusions for any later active ecosystem.
