(type, state_key) -> event_id
state_group (int|None): state group id, if the state has been stored
as a state group. This is usually only None if e.g. the event is
an outlier.

False

tuples

outlier.
delta_ids (dict[(str, str), str]): Delta from ``prev_group``.
(type, state_key) -> event_id. ``None`` for an outlier.
prev_state_events (?): XXX: is this ever set to anything other than
the empty list?
