Audit-by-design
Audit-by-design is the principle that every decision a lending platform makes (human, workflow AI, or agent) produces a tamper-evident record that a regulator or internal auditor can replay.
It is a property of the data model, not a feature added later. Every state change is timestamped, attributed to an actor (user, workflow, agent), linked to the policy version it was evaluated against, and immutable downstream of approval. Audit-by-design is what allows AI to be deployed in regulated lending workflows; the alternative, bolt-on logging and screenshotted approvals, collapses the moment a regulator asks for a methodology trail.
