docs/planning/social.md US-5 (task 13). Models + Alembic migration only, per the sibling-dependency boundary with the Groups API task. - groups: id, name, description, owner_id (FK users, ON DELETE SET NULL -- a group is a durable multi-member community, so it and its full roster survive the owner deleting their account; the API task handles surfacing an ownerless group for reassignment). - group_members: group_id/user_id (both FK, ON DELETE CASCADE -- pure join-table rows with no meaning without either side), role (owner/admin/member native enum, default member), joined_at, unique constraint on (group_id, user_id). - User gets owned_groups / group_memberships relationships. - tests/conftest.py TEST_TABLES updated for truncation between tests. - New tests/test_group_models.py: role assignment, unique-membership rejection, group-delete cascade, member-delete cascade, and owner-delete SET NULL survival -- all verified against real Postgres. Verified: upgrade/downgrade/upgrade round-trip, \d-inspected schema matches spec (FKs, cascade behavior, unique constraint, indexes), full backend suite 166 passed / 0 regressions.
