CBPR+ Cutover Validation

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.

Validate message structure, remittance mapping, cross-rail compatibility, and schema compliance before SWIFT CBPR+ go-live.
