Nice write up, one thing that stood out is the V2 to V3 jump. One of my clients is integrating personal wellness & AI, and we took a slightly different route. The health data and personal data live in separate dbs with an encrypted mapping layer between. This way the model only sees health context attached to a unique pseudo-user level session. Your problem almost seems harder, because the PII is the signal/context. One challenge we are facing is re-identification, e.g rich-health profiles being identifiable in themselves.
Curious if you have thought about that side of things with your V3 implementation?
