* fix(mcp): make key.access_group_ids grants additive over team ceiling A key whose unified access_group_ids grant a private MCP server was having that grant intersected against its team's MCP ceiling, so a key in a team scoped to other servers (or with no own scope) lost the granted server entirely. Resolve access_group_ids once as ungated additive grants and union them on top of the key/team ceiling instead of folding them into the key scope that gets intersected. * test(mcp): align key access-group tests with additive-grant model The previous commit moved key.access_group_ids resolution out of the intersected key ceiling (_get_allowed_mcp_servers_for_key) and into the ungated additive grant path (_get_key_access_group_mcp_server_extras), unioned on top of the team ceiling. Five tests from #28890/#29195 still asserted the old gated / in-key-scope contract and failed: - _get_allowed_mcp_servers_for_key now returns the object_permission ceiling only and never resolves access_group_ids; two tests now assert the group resolver is not called from that path (with and without an object_permission present). - The extras path is ungated, so a group whose assigned_team_ids / assigned_key_ids exclude the caller still contributes its servers. - The end-to-end test asserts the grant surfaces via the extras path rather than the base key path. - Dropped test_key_access_group_ids_empty_returns_no_extras; the empty case is already covered by the extras family's no-groups test. * feat(auth): gate member access-group assignment on keys behind opt-in Non-admin team members could attach access_group_ids to keys they create or update, letting them self-grant resources (MCP servers/models) the team admin never intended. Add an opt-in KEY_ACCESS_GROUP_ASSIGNMENT team-member permission (default-deny) enforced at /key/generate and /key/update; proxy and team admins bypass. Surfaces automatically as a checkbox in the team Member Permissions UI. * fix(auth): gate access-group assignment on /key/regenerate too RegenerateKeyRequest inherits access_group_ids and prepare_key_update_data persists it, so a non-admin key owner could self-grant access groups by regenerating. Apply the same opt-in member gate using the existing key's team. * test(auth): cover member access-group gate and additive MCP grants Add unit tests for enforce_member_can_assign_access_groups (deny without opt-in, allow with opt-in, and proxy-admin / team-admin / non-team-key bypasses) and for _get_key_access_group_mcp_server_extras (no-auth and no-resolved-servers return empty, resolved ids are expanded, errors degrade to no grants).
