// Admin → Events → the run console (EVENTS.md §I, Phase 3).
//
// One run: where it is, what each of its steps did, what a human can still do
// about it, and the diagnostic log underneath. Staff-wide to read; the six
// controls are `admin` + `moderator`, and the server re-checks every one of them
// against the run's live status — this screen predicts, it does not decide.
//
// **It polls rather than streaming.** A run changes on the runner's tick, which
// is a fifteen-second clock, and a console watched for the length of an event is
// a tab left open for two hours: an SSE channel for that is a connection held
// per staff member for a screen that could not use the latency. The poll stops
// the moment the run reaches a terminal status, because a completed run has
// nothing further to say.
//
// **The parked step is the thing this screen exists to make impossible to
// miss.** A run waiting on a GM cue is `running` and healthy-looking, and it will
// stay that way for ever unless somebody presses confirm. It is called out above
// the step list rather than being one row in it.
//
// **Phase 5 gave it a second one of those, and the panel is this phase's real
// deliverable** (§ Observability): a phase whose steps have all finished and
// whose advance condition has not been met is also `running` and also
// healthy-looking. *"Why didn't phase 3 start?"* is answered here, above the
// steps, in the condition builder's own words — and the sentence is the
// SERVER'S. `gates[].where` arrives already rendered, because those labels are
// defined in the condition grammar and a second renderer in the browser would
// be a second opinion about what `gte` reads as.
//
// **Phase 8 gave it a third, and it is the one that outlives the event.** The
// resource ledger is what this run changed in the world and what became of it,
// and its unresolved rows are the reason a `completed` run can still need a
// person — EVENTS.md §L: a run reaches `completed` with `cleanup_status =
// 'incomplete'` rather than being held open, because a tidy `completed` row over
// a shard full of orphaned monsters is the failure that would end this feature's
// credibility on its first bad night. The panel is shown on finished runs for
// exactly that reason, and it is the only panel here whose empty state matters.
