I think the phrase "running in the TEE" is the idiomatic way to describe a program running on the main CPU, attested by the TEE processor, and protected/isolated from other processes on the system (modulo exploits, lol). I'm vaguely familiar with AMD's SEV-SNP, mainly from reading security papers rather than any hands-on experience. I make no claims about Apple's Secure Enclave, though.

    I very much disagree with

    In the Confidentiality/Integrity/Availability triangle, a secondary process running in another operating system gives you integrity, but not confidentiality

    You both should just read the docs

    https://docs.darkbloom.dev/security/overview

    They lay out all the protections they have in place to ensure private prompt execution. The TEE is used to validate the integrity of the binary, and they use other protections like E2EE, SEV-SNP on the coordinator, MacOS security protections (hardened runtime, SIP, kernel protections, etc), plus (from what i can tell an optional enrollment from providers) in Apple's MDM which makes Apple verify the integrity of the system.
