Nothing here ever touches the customer's LinkedIn account * directly. Every LinkedIn action belongs to their agent, which runs on * LinkedGrow's own runner, from its own address, inside the daily caps and the * warm-up ramp. So this endpoint starts and steers agents; it never sends an * invite or a message itself, and it never accepts LinkedIn credentials. That * boundary is what keeps an assistant, and anything that has manipulated one, * from doing something to an account that the safety envelope would refuse. * * The rest of the rules: * 1. Ownership is in the WHERE clause, never a check after the fetch. * 2. Every state change is logged with its provenance, so the dashboard can * say "started by your assistant" instead of showing a change nobody * remembers making. * 3.
