Description
The consolidate command is currently missing. Consolidation leaves a collection logically unchanged, but it accumulates updates with the same data and time, to ensure that there is at most one such for each pair, and that there are none should they accumulate to zero.
Adding a Command::Consolidate variant seems pretty easy, and would be a good way to see which parts of the system play a role in building and installing a dataflow.

Research direction
Start by locating the interactive command definitions and the Command::Consolidate variant mentioned in the issue, then trace how commands are built and installed in the dataflow. The work is done when consolidation preserves the collection logically, combines updates with the same data and time, and removes entries whose accumulated update reaches zero.
