Distillation of the effects→input→state→closures→recursion design session. Ratifies one meta-principle (disciplined surface, mechanism stays in the compiler) as standing orchestrator guidance, separates the three bundled DESIGN.md commitments (content-address-definitions is cheap and kept; total value-purity + RC-no-collector are the expensive ones), and parks four open forks with epistemic status for later brainstorm pickup. No feature ratified here.
