The mesh derives the preparation from the module's own resource instead of each module hand-writing a step beside it (novox/hq ADR 0135). A manifest says one word — `prepares` — and the mesh runs that module's own program in its preparation mode, in the module's own context: the same image, the same environment, the same mounts, because it is the same code. A published port and a fixed address are taken away rather than copied, since the version being replaced still holds them. One word for every kind of module: a Go binary receives `prepare` as its argument, a bundle receives it through the runtime whose entry takes the same word. The control plane answers it like anything else — its own schema stops being a special case, and its hand-written step is gone.
