feat(verify): TDX and Opaque attestation verification stubs - #215
Merged
Conversation
Add verify_tdx_measurement() (MRTD field check + DCAP service probe) and verify_opaque_measurement() (POST to configurable endpoint). Both return PARTIALLY_VERIFIED with descriptive unverified_fields when full verification is unavailable. Wire both into verify_trace_claim() dispatch. 12 unit tests, all passing.
