Cache storage scales linearly with epochs. Process peak includes Python, imported libraries and generated input/output matrices; it is not the cache size. Structured paths construct no whole-record covariance, factor or projection matrix.
These are supplied-covariance software checks. Covariance estimation, bounded parameter uncertainty, predictive adequacy and native streaming integration remain separate.
