- decision: the Monad-style iteration framework will be abandoned - the job-planning will be recast in terms of the iter-tree-explorer - job-planning and frame dispatch will be disentangled - the Scheduler will deliberately offer a high-level interface - on this high-level, Scheduler will support dependency management - the low-level implementation of the Scheduler will be based on Activity verbs
