dsfb-chemical-engineering-edge

DSFB deterministic, read-only residual-semiotics layer for chemical-engineering and chemometric process monitoring (CPU / edge). Ingests residuals from established chemometrics detectors (PCA, PLS, EWMA, CUSUM, Hotelling T2, distribution distances, spectral and process-structure detectors), applies Drift-Slew Fusion Bootstrap (drift, slew, admissibility envelopes, detector consensus, chemical heuristics bank), and emits auditable structural episodes with deterministic replay. No GPU required. Unsafe code is forbidden.
