edge lab

a three-node single-board cluster under the desk that runs the whole stack nightly — my cheapest and most honest staging environment.

platform

Mono cluster

why

if the platform only works on cloud instances with infinite memory, it doesn't work. the lab is three small boards, one switch, and nixos configs that rebuild the world from a git push.

notes

  • k3s on nixos, fully declarative — the sd cards are disposable by design
  • every release candidate soaks here overnight before it goes anywhere real
  • has caught two memory leaks and one dns disaster that the cloud environments politely hid

also doubles as a space heater during monsoon season.
