The risk is rarely one bad file.
AI-generated code tends to create local correctness: a route works, a component renders, a mock test passes, or a demo flow looks complete. Production risk usually appears where those local pieces cross product boundaries: auth, tenants, data exports, payments, deployments, webhooks, and agent-accessible actions.
The fastest useful review is not a generic vulnerability scan. It is a boundary-first inspection that identifies which mistakes could expose customer data, mutate business-critical state, break billing, fail an enterprise review, or block a launch.
