## Automated review Re-reviewed this PR (diff + full PR-branch source, cross-checked against `main`). No correctness bugs confirmed — the core change (gate `preloadOwner` on `isMetadataObject`, add metalake-scope short-circuits for USER/GROUP/ROLE) is narrowly scoped, mirrors the existing TABLE/SCHEMA/CATALOG short-circuit pattern, and is backed by thorough regression/query-count tests. I initially suspected the `Entity.EntityType.valueOf(type.name())` → `MetadataObjectUtil::toEntityType` refactor (`MetadataAuthzHelper.java`) could throw at class-init time for `MODEL_VERSION`, but confirmed `MetadataObjectUtil.TYPE_TO_TYPE_MAP` covers all `MetadataObject.Type` values on this branch — not an issue. 5 minor findings, none blocking: 1. **[MetadataAuthzHelper.java](https://github.com/apache/gravitino/blob/adf6cc00fa68f233cc1783be9424a1f46e50725f/server-common/src/main/java/org/apache/gravitino/server/authorization/MetadataAuthzHelper.java#L165-L172) — owner short-circuit skips per-object deny for principal lists.** `principalListPaths`'s `parentOwnerPath(METALAKE_ONLY_SCOPE)` carries an empty `denyPrivileges` set, so a metalake owner now sees the *entire* unfiltered user/group/role list without any per-object deny check — previously USER/GROUP/ROLE listing had no short-circuit at all and always ran full per-object authorization. This mirrors the pre-existing TABLE/SCHEMA/CATALOG owner-path pattern and is explicitly asserted by `testPrincipalListMetalakeOwner` (zero `hasDenyPolicy` calls), so it looks intentional — but it's the first time owner-supremacy applies to *principal* listings rather than data objects. Worth an explicit confirmation that hiding an individual user/group/role from a metalake owner via a deny policy is not a supported case. 2. **[TestPrincipalListQueryCount.java#L486](https://github.com/apache/gravitino/blob/adf6cc00fa68f233cc1783be9424a1f46e50725f/server-common/src/test/java/org/apache/gravitino/server/authorization/TestPrincipalListQueryCount.java#L486) — duplicates existing H2 backend test bootstrap.** This test manually re-implements H2/`JDBCBackend` bootstrap (Config setup, `EntityIdService.initialize(new RelationalEntityStoreIdResolver())`, teardown) that `core/src/test/java/org/apache/gravitino/storage/relational/BackendTestExtension.java` already provides. `server-common/build.gradle.kts` only depends on `core`'s main sourceSet, not its test fixtures, so this isn't a trivial reuse today — flagging as a maintenance-cost duplication to consider (test-fixtures dependency, or accept consciously). 3. **[MetadataAuthzHelper.java#L100-L101](https://github.com/apache/gravitino/blob/adf6cc00fa68f233cc1783be9424a1f46e50725f/server-common/src/main/java/org/apache/gravitino/server/authorization/MetadataAuthzHelper.java#L100-L101) — duplicate-valued constant.** `METALAKE_ONLY_SCOPE = "METALAKE"` duplicates the value of the pre-existing `CATALOG_PARENT_SCOPES = "METALAKE"` right below it. Two differently-named constants holding the same literal risk silently desyncing later; consider reusing one. 4. **[TestPrincipalListQueryCount.java#L262](https://github.com/apache/gravitino/blob/adf6cc00fa68f233cc1783be9424a1f46e50725f/server-common/src/test/java/org/apache/gravitino/server/authorization/TestPrincipalListQueryCount.java#L262) — redundant UPDATE in test setup.** `insertPrincipals`'s `UPDATE role_meta SET properties = '{}' WHERE properties IS NULL` has no `metalake_id` filter, so each of the three size iterations (1, 1003, 10000) rescans/rewrites all previously-inserted roles from earlier metalakes in the same run rather than just the newly inserted batch. Harmless at this scale, but wasted work a `WHERE metalake_id = ?` would avoid. 5. **[MetadataAuthzHelper.java#L406](https://github.com/apache/gravitino/blob/adf6cc00fa68f233cc1783be9424a1f46e50725f/server-common/src/main/java/org/apache/gravitino/server/authorization/MetadataAuthzHelper.java#L406) — untested branch of the new gate.** The new `isMetadataObject` gate on `preloadOwner` has no test for entity types that are neither metadata objects nor principals (e.g. `MODEL_VERSION`, `TABLE_STATISTIC`, `AUDIT`). Currently a dead path (no REST call site passes those types here), so low risk — noting only for coverage completeness. --- 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
