Ran 1 shell command 

● Applied and verified — the key still authenticates, now with SSH forwarding disabled (can't be used as a network pivot if the key ever leaks).
  Backup saved.

  Here's the honest picture and the two decisions that are genuinely yours to make (this is where I don't want to guess and risk locking you out):

  What's already true (good): access = one key (this Hetzner box), over the tunnel only, key-only, no root, firewall + stealth on. So "only this
  Hetzner machine reaches it" is done.

  One reachability note: FileVault is on, so after a reboot/power-loss the Mac won't come back online until someone enters the password at the console
  (PiKVM). That's a security-vs-availability tradeoff you should know about.

● User answered Claude's questions:
  ⎿  · Access is already limited to this Hetzner key over the tunnel only. How much further should I restrict what that key can DO on the Mac (in case
     Hetzner/the key is ever compromised)? → Full build-only whitelist
     · If this Hetzner box is deleted, the ONLY remaining way in is PiKVM (physical console). Want a second, independent remote recovery path? → Add 
     my laptop's SSH key

· Clauding… (20m 55s · ↓ 77.9k tokens · almost done thinking with max effort)

  ❯ i want both options 1 and 2 and the ssh key has to be stored in gcloud and encrypted and i will have a recovery program in lockdown that i can  
    execute securely
