Notes and record state

Record note
The June 2018 hack is already represented in canonical history and is not duplicated. A separate reopening event records the July 15, 2018 service return. HEI retains inactive rather than dead status because current trackers show zero active markets but no definitive shutdown announcement or terminal operating date has been established.
Revision state
Records may be incomplete, approximate, contested, or revised as better evidence becomes available.
