-- Room roles as their own table, mirroring 0013's move of tags into `room_tag`. One row
|
|
-- per (room, account). Generated from packages/domain/src/rooms-db.ts (ROOM_SCHEMA_DDL) —
|
|
-- keep in sync.
|
|
--
|
|
-- The row is the client's `Roles` entry shape:
|
|
-- { "AccountId": …, "Role": …, "LastChangedByAccountId": …, "InvitedRole": … }
|
|
-- `role` is the member's CURRENT role tier (10 Host, 20 Moderator, 30 CoOwner,
|
|
-- 255 Creator); `invited_role` is the tier they have been OFFERED but not yet accepted —
|
|
-- usually higher than `role`, and 0 when no invitation is pending. `last_changed_by` is
|
|
-- who last touched the row; NULL for creator entries, matching the blob's
|
|
-- `LastChangedByAccountId: null`.
|
|
--
|
|
-- The table is AUTHORITATIVE and the blob's `Roles` key is removed below, the same
|
|
-- arrangement 0013 gave tags: `serializeRoom` drops `Roles` on write and the reads
|
|
-- re-attach it (attachRoles), so the room DTO the client sees is unchanged and the two
|
|
-- copies can't drift. `getContributedRooms` now matches on this table instead of running
|
|
-- `json_each` over every blob.
