When querying across two points in time this describes the change in
the finding between the two points: CHANGED, UNCHANGED, ADDED, or
REMOVED. Findings can not be deleted, so REMOVED implies that the
finding at timestamp does not match the filter specified, but it did
at timestamp - compare_duration. If there was no compare_duration
supplied in the request the state change will be: UNUSED
Values:
UNUSED (0):
State change is unused, this is the canonical
default for this enum.
CHANGED (1):
The finding has changed state in some way
between the points in time and existed at both
points.
UNCHANGED (2):
The finding has not changed state between the
points in time and existed at both points.
ADDED (3):
The finding was created between the points in
time.
REMOVED (4):
The finding at timestamp does not match the filter
specified, but it did at timestamp - compare_duration.
