What you were describing, an enforced period of helplessness, observation, being bound to a person of complete power... almost like having a baby, wasn't it?

That itself suggested an answer. There were security firms that provided the physical and digital protection for buildings and property, and they were the weak hunchbacked virgins compared to the chad security companies who optimized for executive-level child safety and surveillance. What you were after wasn't really anything more complicated than a baby monitor, and there were people out there who'd already started the strange project of raising an android mind from childhood rather than printing the full version into an adult body. The expertise on offer from these companies was discreet, ruthless, and provided a plausible explanation if anyone went looking. It would generate a secret that would cover for a deeper secret.

You could find that expertise in house, but if you were being honest you'd probably want to go with a Crown&Slate subsidiary. Their entire existence and corporate culture revolved around letter of the law contracts and they'd have to be really pushed into a corner before they considered playing with that.
