Successful Response

- AcceptedOut
  - `tenant_id` string, uuid, required
  - `tenant_name` string, required
  - `role` 'owner' | 'member', required: Who somebody is in one workspace. Two, by the owner's decision of 2026-09-18, and the argument is the one he made: four roles that collapse to two predicates are not four roles. OWNER and ADMIN differed in two lines in the whole codebase; EDITOR and VIEWER in one. Worse, four roles plus per-connection grants meant the same fact could be stated twice and disagree — a role saying VIEWER while a grant said writer, with the winner decided across sixteen separate gates. One axis cannot express the contradiction. ``OWNER`` does everything: billing, team, connecting accounts, approving changes, and reading and writing on every connection. ``MEMBER`` does exactly what it was given, per connection, in ``connection_grants.level``. A member with no row anywhere can sign in and see that nothing has been shared with them yet, and that is all. Persisted as a plain string: VARCHAR(32), no CHECK constraint, no native Postgres type, so this is a code change and not a migration.
