The Reference and its editions

The Reference is separately constituted as a publication series belonging to this Suite. Its readers need a useful answer about selection, combination, shared architecture or an unavailable contribution. It returns to this membership account and to the publications that supply the answer. It is published as one Markdown file alongside the member DPFs.

A later Reference edition is admitted when its answers agree with the editions it presents, its available and planned contributions are distinguishable, and its readers can return to those sources. A different audience or use that defeats these conditions requires a decision about a different Reference series. A superseded or retired edition remains historical; its date alone cannot establish that its advice still applies.
