Books and records rules require preservation of communications relating to advice and recommendations, and to the movement of funds, in an accessible place, for a defined period with the earliest portion held locally. The practical consequence for automation is direct: any new channel a system introduces becomes a retention obligation from the first message, not from the first audit. Marketing rules treat testimonials and endorsements as permitted subject to disclosure and oversight, which makes automated content generation or review solicitation an advertisement subject to review and archiving. Privacy rules now require an incident response programme with individual notification inside a defined window and documented oversight of service providers, so adding a vendor that touches customer information is a diligence exercise rather than an infrastructure choice. Above all of it sits a fiduciary duty, which is why a recommendation reaches a client through an adviser rather than directly from a system.
