description: |-
|
|
Paginates over the space tree in a depth-first manner to locate child rooms of a given space.
|
|
|
|
Where a child room is unknown to the local server, federation is used to fill in the details.
|
|
The servers listed in the `via` array should be contacted to attempt to fill in missing rooms.
|
|
|
|
Only [`m.space.child`](#mspacechild) state events of the room are considered. Invalid child
|
|
rooms and parent events are not covered by this endpoint.
