E.4.DPF.DA:10 - Rationale

FPF needed E.2.DA because a local edit can improve one pattern while harming the whole language. DPF packages need the analogous but narrower instrument: a package can have good patterns while failing as a domain framework. Domain source grounding, relation architecture, first-entry adoption, package publication, and refresh are package-level effects.

The coordinate set mirrors the spirit of the FPF Pillars but changes the adequacy question. FPF asks whether the whole framework remains broadly first-principle and cross-domain. A DPF asks whether one bounded domain or local framework is strong enough for its declared use while preserving dependency on FPF Core and a route back to its domain sources. D12 makes that field-scale question explicit; the sequence-versus-simultaneity architecture probe prevents a source diagram or chapter order from supplying the answer by appearance.
