Enclosing class:
GraphGenerator
static final class GraphGenerator.ReportThrottleextends Object
Decide whether a repeated report is due, and remember the decision.

Pure enough to unit test and free of router context, so the "first report is never throttled, a changed one is never delayed, an unchanged one repeats on a timer" rule is pinned by tests rather than by reading the caller.

      Synchronized because the stall report is reached from the 90s sync task and the 10s watchdog, which run on different threads.

      Parameters:
      now - current wall-clock ms
      signature - value identifying the state being reported
      minIntervalMs - shortest gap between two identical reports
      Returns:
      true if the caller should log now
