chore(api): derive role guards from an ownership model - #2009
Conversation
Each role-management guard tested provider namespaces on its own, and the tests disagreed with one another. `reject_managed_provider` and `reject_managed_role` refuse the `system` namespace and any namespace a configured role provider owns. The storage layer allows only `lakekeeper` and `system`. Reading the code left it unclear which rule was the real one. This commit gives the two underlying questions names. `identity_owner` says who owns a role's name, description, provider binding and existence. `membership_owner` says who owns the set of members assigned to it. The two answers differ for the `system` namespace, whose identity is fixed while an instance admin may still edit its membership, so a single rule could never describe both. `reject_managed_provider` and `reject_managed_role` now read `identity_owner`. A new guard, `reject_provider_owned_membership`, takes over the two membership sites. It states the axis it enforces, and an authorizer that manages assignments itself can call the same function. Behaviour is unchanged.
WalkthroughThe role API adds ownership classification for identities and memberships. Existing provider and role guards use the classification. Membership endpoints reject changes to provider-owned roles before backend-specific authorization logic. ChangesRole ownership enforcement
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to This change separates role identity and membership ownership so system-role memberships remain editable under their dedicated rules while provider-owned memberships are rejected. Focused tests for each ownership category are still needed to reduce the chance of authorization regressions. Poem
