-    uint64 sourceChainSelector; // Remote source chain selector that the Merkle Root is scoped to
-    bytes32 merkleRoot; // Merkle root of a single remote source chain
+    Internal.MerkleRoot[] merkleRoots; // Collection of merkle roots per source chain to commit
+    IRMNV2.Signature[] rmnSignatures; // RMN signatures on the merkle roots


If we want to be accurate these aren't signatures on the merkle roots exactly. They're signatures on a particular RMN report that consists of "lane updates" that match the updates in the merkleRoots array above. Maybe reference RMNRemote.verify() for folks who want to see the exact message being signed.

you're right. If I make additional changes, I'll fix the comment :)

+  function verify(Internal.MerkleRoot[] memory merkleRoots, Signature[] memory signatures) external view;


A basic docstring on the expected behavior of this function might be useful (e.g maybe for implementing mocks), i.e "verifies RMN signatures against provided MerkleRoot structs and reverts on invalid signatures"
