The categorizations are blunt by design: acceptable, needs review, unacceptable. The detail that matters most is the provenance one: the builder maintains citations to source documents for each rule, so every automated call can be traced back to the firm's own guidelines.",

That is the anti-black-box pitch: the AI does not substitute the firm's judgment, it operationalizes it.
