A runner cannot limit which repositories it builds #66

runner next claims the oldest pending build in the whole queue, so every runner executes every repository's steps. The Admin wiki states the consequence plainly: "treat the runner machine as executing whatever your users push."

That is fine for a runner on the server itself. It rules out running one anywhere else — a home machine, a workstation, a box with credentials for one deployment — because it will sooner or later claim a build for a repository that has nothing to do with it. With open registration, that includes repositories belonging to people you have never met.

A runner should be able to name the repositories it will take work for.
