+title: Fix storage weight reclaim bug.

+doc:
+  - audience: Runtime Dev
+    description: |
+      A bug in storage weight reclaim signed extension is fixed. The bug was causing an underestimate of the proof size when the post dispatch info was underestimating the proof size and the pre dispatch info was overestimating the proof size at the same time.

+title: PoV-Reclaim - Set `BlockWeight` to node-side PoV size if mismatch is detected
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      After this change, the `StorageWeightReclaim` `SignedExtension` will check the node-side PoV size after every
+      extrinsic. If we detect a case where the returned proof size is higher than the `BlockWeight` value of the
+      runtime, we set `BlockWeight` to the size returned from the node.
