Build meta-schemas with base cases that terminate recursion

Why This Is a Principle

This derives from Working Memory Capacity Limit (working memory limits) and Externalization Exposes Hidden Structure (externalization exposes gaps). The principle prescribes a specific design constraint for recursive meta-cognition: every recursive examination must have a stopping condition that leads to action rather than further analysis. This follows from Demonstrative Knowledge Requires Indemonstrable Foundations (all demonstrative knowledge rests on indemonstrable first principles) - at some level you must stop proving and start acting. The principle is actionable and prevents the failure mode of infinite regress.
