Version: 2026-03-04__05 This preprint is a methodological/theory note that clarifies an aggregation principle for long-horizon self-correction under the Minimal Error-Correction Loop (MECL) perspective. The core claim is non-compensatory gating across necessary correction functions; multiplicative aggregation is used only as a baseline representation. Scope: This note focuses on process-level aggregation and diagnostic implications. It does not provide generative dynamic closure, stability proofs, empirical causal testing, or policy prescriptions.
