Tdx Preflight

Can this exact image boot on this host? The one call a launch/upgrade preflight makes.

A check against both a host profile and the measurement set, so it hangs off neither. The API fingerprints the submitted profile and answers whether a published measurement for the caller's (version, rc) carries that fingerprint -- the whole launch decision in one boolean:

  • launchable: true -> the VM will attest; launch.
  • launchable: false -> register the class (POST /servers/tdx/host_profiles), then retry once Chutes publishes its measurement.

Stores nothing and reveals nothing beyond the answer -- not the full measurement set, not whether a profile row exists. Signed by the miner hotkey, so the signature covers the body.
