Included review availability: This review used your included allowance. Your plan provides up to 10 included reviews per hour; 3 remain after this review.
Apply and revert validate every entry first, but a later write can still throw after earlier entries were written. The exception reached the generic handler, which returned "Internal error" without saying what had changed and skipped MarkSceneDirty. Catch the failure per entry, mark the scene dirty when anything changed, log the exception, and return an error that says how many overrides completed, which one failed, and that nothing was rolled back.

Description
Makes it possible to identify the cause when editing a Prefab asset does not change what the scene shows because scene-side overrides remain. Adds override listing and targeted apply and revert operations to
manage_prefabs.Type of Change
Changes Made
list_overridesreturnspropertyPath,instanceValue, andprefabValuefor each object and component, and lists added and removed components and GameObjects.apply_overrides/revert_overridesare limited to the target object. Children, components, properties, and structural overrides can be selected explicitly. Selecting a child by a name shared by several siblings is rejected as ambiguous, and selection by instance ID is limited to that object alone.Compatibility / Package Source

Additional Notes
Applying overrides changes the Prefab asset and therefore also affects other instances. Retrieve selection indices again after writing. Unreadable serialized values are indicated by availability flags. Operations use
AutomatedActionand do not guarantee that entries are added to the Undo history. Windows, Linux, and the other CI-specified Unity versions are not verified.The scope of array application and handling of cyclic references were checked against Unity's official ApplyPropertyOverride and SerializedProperty.Next documentation.
Fork CI verification
Checked the GitHub Actions results for the same commit
9ee1c16f2f90ef1f2e05fce60430ad6a2badd1f2. The Python tests succeeded, as did the harness tests that run without Unity.C# compilation also succeeded with Unity 6000.0.75f1. Runtime and Editor were compiled for each of the Windows, macOS, and Linux configurations.
The docs build succeeded. The generated-docs drift check also succeeded.
The E2E tests and the Unity Editor tests that require a license were skipped.
The upstream GitHub Actions are waiting for a maintainer to approve the run for the current commit. The CI successes above are results from runs on the fork that verified the same commit.
Review follow-up
Commit
78b8f0ed7cd5d152294b8587fdb264c306d683a7addresses the automated review finding that a failure part-way through applying or reverting overrides left partial changes behind a generic "Internal error". Each entry is now applied inside a guard: the scene is marked dirty when anything changed, the exception is logged, and the response says how many overrides completed, which one failed (type, child path, index) and that nothing was rolled back. The success path and the validation phase are unchanged. A unit test covers the error response for apply and revert; a real mid-loop failure cannot be provoked deterministically, so that path is covered by review only.Verification for the latest commit:
