How the enclave proves itself
The enclave measures itself at boot — bootloader, kernel, app image — and signs the result. You can fetch that signature, check it against what we say we shipped, and refuse to talk to anything that doesn't match.
- PCR0 — bootloader and firmware hash.
- PCR1 — kernel and init image hash.
- PCR2 — application image hash. This is the one that changes when MESH ships.
- Reference values are tied to the release pipeline. They move when code moves, not before.
