ECCN / Dual-Use Classification

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Product attributes -> ECCN (EAR) + EU Annex I + controlling regime + licence logic including 2025 emerging-tech controls (ART-94) -> Merkle integrity (cry-04). EU Annex I updated 15 Nov 2025.
