What changes is that "the name is unique" — until now an unenforced expectation — becomes real, scoped to the owner account, and the owner's username is surfaced so two groups called "photos" on different nodes can be told apart. Hub: - `groups` gains a functional unique index `uq_groups_owner_name` on `(admin_id, lower(name))` (model + migration c3d4e5f6a7b8). The migration pre-flights: if the data already clashes it aborts and lists the offending (admin_id, name) pairs rather than renaming anyone's group. meshbay.org checked clean. - `create_group` trims the name, rejects blank (422) and an owner-scoped case-insensitive clash (409), with an IntegrityError backstop for the race, and returns `owner_username`. - `owner_username` added to `/v1/groups/mine`, `GET /v1/groups` (local rows), `POST /v1/groups/{id}/join`, `GET /v1/admin/groups`. SPA: - new `static/group-name.js` — `<GroupName name owner [inline]>` renders the name with the `@owner` handle on a smaller grey line under it. - used in the sidebar, the group-page header, Explore cards, the Admin groups table, and cross-group Search (via a widened `cacheGroupIndex` carrying the owner). Delete/leave confirmations show `name@owner` inline. - federated Explore rows show `@<source_hub>` instead of an account. Design record and the locked decisions: ~/next/groupnames.md (out of repo). MNP unchanged. Tests: test_group_name_unique.py, test_group_name_migration.py.
