KYC Onboarding & Customer Due Diligence

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.
Reading mode (RUNBOOK): Run these steps in order. A real onboarding case is worked through these checks by a compliance analyst; note that the identity-document checklist lands last here, after the screening and adverse-media steps, which is backwards for an analyst opening a new file. That inversion is an ordering concern, tracked separately from this declaration.
