Module isolation safely enables pedagogical breadth: multiple algorithm variants and simplified implementations serve learning goals without production risk, because module boundaries contain the impact of any performance or correctness tradeoff.
Breadth (multiple variants) and tolerance (brute-force implementations) are both safe because module isolation bounds blast radius
