Trust raises ally stats and maxes at 200%. Module upgrades also require a certain amount of trust (level 2 is 50%, level 3 is 100%). The only way to raise trust outside of using an operator in the RIIC (base) is to bring them to missions, with higher sanity cost missions granting more trust. An operator's debut event grants additional trust, so right now Wulfenite, Brigid and Necrass all get a boost when you use them in the event, so most people leave them in their autos when material farming to trust farm at the same time.
