runTag static method
The prefix every line of a resource's work carries on the node log stream.
Public because it is a wire format in all but name: a client filtering the
stream for one resource has to build the same string. Deliberately the same
bracketed shape NodeFormulaService.runTag uses, so the dashboard's log
filter works on blueprint applies with nothing changed.
Implementation
static String runTag(ResourceId id) => '[$id]';
