// When a run last moved.
//
// The collection had `created` and nothing else, so "is this run still alive or
// did it die" had no answer: the dashboard read a field that was not there, got
// NaN, and called every live run stalled. `status` alone cannot answer it -- a
// killed process leaves its record saying `running` for ever -- so the honest
// signal is the timestamp of the last update.
