Brute-force algorithms, bounded collections, and in-process simulation are acceptable pedagogical trade-offs because each module is a standalone learning artifact with no cross-module dependencies — simplifications that would be dangerous in production are safe when confined to self-contained demonstrations.
module isolation is the safety boundary for pedagogical simplifications; cross-module reuse means a simplified module becomes a production dependency
