OOB memberships are a special case of outlier events: they are membership events

for federated rooms that we aren't full members of. Examples include invites
|
|
received over federation, and rejections for such invites.
|
|
|
|
The concept of an OOB membership is needed because these events need to be
|
|
processed as if they're new regular events (e.g. updating membership state in
|
|
the database, relaying to clients via /sync, etc) despite being outliers.
