I did a lot of research into this the other day while bored, based on all the gov contracts, the stack doesn't seem that complex, NEC seem to provide very nice tooling and it seems to work well with Palantir.
Something like: [Android App – Kotlin + CameraX + ML Kit] -> [HTTPS/mTLS] -> [AWS API Gateway -> Palantir Foundry middleware] -> [NEC face match + NeoFace] -> [DHS IDENT/HART (Thales fingerprints)] -> [PostgreSQL + Splunk audit]
Here was my reading/watching:

I would encourage someone who wants to dig deeper to FOIA accordingly using https://www.muckrock.com/ ; think of it as being part investigator, part archeologist, part systems analyst.
