❯ also you need to harden this mac to allow only build commands from this hetzner machine, and reactor incase the hetzner cloud does go down or 
  instance gets deleted, we want to be secure ubt not get locked out like an idiot

● Verified: nothing lost. The Mac is clean, exactly matches origin/main @ 84ea3a8, all files present, my build-offload fix intact, dashboard healthy,
  env flags in place. The stash only dropped copies identical to what's already in git — the source of truth is GitHub, and the Mac matches it.

  Let me finish the "install new versions" proof (the APK is built), then I'll address hardening. Installing the Flutter app on the emulator:

  Ran 1 shell command 

● App installed ("Success") and launched via reactor-build. Let me see it running:

  Read 1 file 

● The Flutter app installed and its icon is now on the emulator (blue Flutter icon in the dock) — so the full loop works: build APK → reactor-build 
  emu install → on the device. The whole mobile toolchain (Flutter/Android/iOS/emulators) is operational and controllable from here.

  Now to your hardening + anti-lockout ask — this is exactly where I should be careful, so let me first map the current security posture before
  changing anything:

  Ran 1 shell command 

● Good news on posture — the Mac is already access-hardened: only one SSH key (this Hetzner box's) is authorized, SSH is key-only (no passwords, no
  root), the only inbound path is the Cloudflare tunnel (no public SSH port; rapportd is a local Apple service), the firewall + stealth mode are on,
  FileVault is on, and PiKVM (console + your aiq password) is an always-available break-glass. So "only this Hetzner machine can reach it" is
  essentially already true.
