Train · phaddad90 bundle Run a batch of work as a merge train - N streams building concurrently in isolated worktrees, each self-verifying to green, integrated once and shipped once. Use for ANY multi-item batch of work in ANY repo, in place of building serially in the shared tree. Modes - "init" to onboard or retrain a repo (measures its substrate first), "retro" to fold a finished train's lessons back into the method. Triggers - "run a train", "train init", "train retro", "parallel streams", "batch this work".
