Consumer Protection & FCA Consumer Duty

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.

Vulnerability assessment > fair-value assessment > MiFID costs & charges > PRIIPs KID compliance > Consumer Duty board MI > composite consumer-duty mandate.
