 * Answers planning requests against a feed it holds on to.

 * and copying it to the other side of a worker boundary would cost more than building it did, so
 * only the journeys asked for are sent back, and those are a few thousand objects at most.
 *
 * This knows nothing about workers, so it can be driven directly by a test or by a caller that
 * would rather not have one.
