 ### Features
 
+- Added `ArrayMetadataV3Partial`, `GroupMetadataV3Partial`,
+  `ArrayMetadataV2Partial`, and `GroupMetadataV2Partial` — sibling
+  TypedDicts to the existing full metadata types, declared with
+  `total=False` so every field is `NotRequired`. Use these when typing
+  dicts that intentionally hold a subset of a complete metadata document

+  equivalence test pins each `Partial` to the keys and value types of
+  its full sibling so the two cannot drift.
