CALL NUMBER: software_design_patterns.clean_architecture DEFINITION: Layered architecture with independent frameworks and clear dependency rules pointing inward.

Invoke this skill to understand clean_architecture down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.

THE RELATIVE ROOT (the import cone, by lib)

from software_design_patterns

• hexagonal_architecture_pattern (d1): Ports_and_adapters architecture that separates core business logic from external concerns, with ports defining interfaces and adapters implementing them.

CONSUMERS (what needs this)

clean_architecture_pattern

---

Projected from the software design patterns KB (211 concepts / 36 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.

(leaf — this is an actual skill.)
