 Exactly one task is active at a time ([execution-policy.md](execution-policy.md)). Work is authorized per range of rows of this table ([execution-prompt.md](execution-prompt.md)); within a range, start the first `planned` task whose dependencies are delivered or complete.
 `Depends on` lists only real dependencies; the row order is the serial sequence. A `blocked` task waits on the named register entries, and `next` continues with tasks that do not depend on it.
