The powder coat oven in my shop is the proof. It was designed in MyGarage — every decision recorded with its reason, every rejected alternative kept alongside — and the build plan came out of that design. Its controller firmware lives there too, as code MyGarage can read, version, and compile.
Now I run it through the same system that helped build it. I say: "Look up the spec sheet for this powder and add it to the powder coat oven." That's the whole instruction. It finds the manufacturer's data sheet, files it where I can cite it later, reads the cure schedule off the page, and loads it on the oven. Nothing heats up. I rack the parts, walk over, and press Start on the oven itself. While it runs, MyGarage watches the zones, and my phone buzzes when the cure completes — the oven saying so, not a kitchen timer. The schedule that produced a good finish is saved; the next batch is one tap.
That's the loop. A machine the shop designed, built, and now talks to.
