E.4:10 - Rationale

An ecosystem-architecture record identifies the selected structures across FPF patterns, frameworks, source packs, exact presentation carriers, access routes, quality records, and decisions. Direct assertions state relation meaning and decision rationale. Source-return and currentness patterns qualify carriers and access routes. Architecture work therefore names the selected structures and applies the relevant direct pattern to each neighboring claim.

The old Core, Tooling Reference, and Pedagogical Companion distinction remains valuable, but it is only one family partition. Domain and local principle frameworks need their own framework editions so they can depend on Core without redefining it.
