| One DPF result is already known and sufficient. | Use that DPF directly; do not require a Reference detour. |
| Several DPFs may apply or the applicable DPF is unclear. | Use the Reference’s problem-led route when a current trustworthy Reference is available. |
| The Suite exists before the Reference product series is included. | Keep the Suite and the DPF product series that already belong to it identifiable. Make no claim that a Reference route is available; direct use remains allowed. |
| A DPF whose product series belongs to the Suite publishes a later edition. | Test the edition-to-product-series admission, then refresh only affected Reference claims or warnings. Do not create a Suite edition. |
| A product series in the Suite no longer qualifies. | Warn and return to the decision branch. While the same product series and Suite continue, belonging remains until removal; restoration before removal keeps the occurrence, while removal followed by inclusion creates another. |
| A DPF product or the Reference is temporarily unavailable or stale. | Keep the belongs-to occurrence when it still obtains, show the action-changing warning, and do not claim that the unavailable product currently supplies its route or result. |
| The Suite temporarily contains one product series or none under its preservation rule. | Present no current cross-DPF answer; name the restoration, review, or retirement return. |
| A DPF product series has ended or its identity rule identifies another series. | End its current belonging to the Suite when the series ends or the reidentification takes effect; no prior removal is required. Show that the old product series belonged in the past. Include the new product series only through a new inclusion decision and occurrence. |
| The Suite has ended or retired. | When the end or retirement decision takes effect, end every current belongs-to occurrence without separate removals. Keep the historical collection, products, editions, and past belonging identifiable, but require another constitution decision and new inclusions for later active Suite use. |
| A Reference projection cannot return to the authoritative Suite and product-series account. | Label it orientation only; do not claim access to the authoritative belongs-to facts, availability, or currentness. |
| One carrier exposes several products. | Identify each constituent; infer no merged identity, edition, maintenance, or stronger relation. |
| An answer needs a result the ecosystem does not supply. | Name the product gap and return to a direct source, an existing-DPF change, a new-DPF question, or an explicit stop. |
