Detailed Description

A fake actuator board: binds the actuator command UDP port on loopback and records what was actually sent, and when.

This is the only thing that can answer "did the valve move when we said it would". Every other way of testing the delay feature measures a clock somewhere in the sequencer, which is how a staggered send could be shadowed by an unstaged one for as long as it was: the arithmetic was right and the commands still went out together. Assert on the wire.

Shared by test_actuator_delays (the mechanism) and test_hold_rules (the caller).
