Mathematical reduction (closed-form formulas, modular arithmetic) constitutes a third axis of the elimination principle alongside construction-based validation elimination and isolation-based coupling elimination: where construction eliminates runtime checks and isolation eliminates inter-module dependencies, mathematical reduction eliminates computational phases entirely.
Mathematical insight replaces computation (depth-2) and the repo's coherence comes from elimination not enforcement (depth-6); math reduction is the missing third arm — it eliminates computational phases just as construction eliminates validation and isolation eliminates coupling
