Every rooms-client mutation (roles, invite, accessibility/publish, room
fields, sub-room ops, permissions, playlists) goes through
NLDBPDCNNCF.BDBHCEGKGDC<TResult>, the same helper and instantiation as
"clone room", which reads {success, value, error}. A bare room-details body
has no success, so the client rejected it with the message-less
"Exception of type 'CEMNLBKJABA' was thrown" (seen on co-owner invite)
although the server had applied the change.
RecNetEnvelopeAttribute wraps those handlers: 2xx becomes
{success:true, value, error:""}, refusals become 200
{success:false, value:null, error:<message>}.
- Room roles: list the creator as Creator (255), not CoOwner (30). The
client takes the local role from the Roles list and only lets a player
edit roles below their own (Creator excepted), so the creator could not
edit Co-Owner and Creator permissions. Enforce the role ladder on the
server (RoomRoleRules), let invitees accept (PUT roles/{me} role=30) and
reject (PUT roles/{me}/invite role=0), send message Types 62/60/61, and
push RoomUpdate after every role change.
- Permissions: persist PUT subrooms/{sub}/permissions cells in a new
RoomRolePermissions table, serve them from photon_access_token (plus a
roomserver/ twin) and push PhotonAccessToken to the sub-room.
- Publish: player-owned rooms are never IsRRO on the wire; the client
hides Publish and every room setting for an RRO.
- Sub-rooms: wire SubRoomId = OrderIndex + 1 (the client will not load a
sub-room with id 0), new rooms always get a named Home sub-room, and a
startup pass repairs rooms without one.
- Instance browser: per-room Redis presence index, live players only,
private instances for the people allowed in, real IsFull.
- Room/sub-room settings: creator or accepted co-owner everywhere.
