Remove it.only to avoid running a single test only.

This will cripple the test suite.

-it.only("should return true if claim was missed in previous epoch", async () => {
+it("should return true if claim was missed in previous epoch", async () => {

Run this to detect any lingering “only” in tests:

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Handle empty Graph response and align comment with logic.

• If fetchLastSavedMessage returns null/undefined, destructuring throws. Provide safe defaults (lastSavedCount = 0, lastSavedSnapshot = ZeroHash).
• The comment says “adding 1 to the message index,” but code doesn’t add 1. Either remove the note or implement the +1 if correct.

Apply this diff:

   } catch {
     const veaInboxAddress = await veaInbox.getAddress();
-    const { id: lastSavedMessageId, stateRoot: lastSavedStateRoot } = await fetchLastSavedMessage(
-      veaInboxAddress,
-      chainId
-    );
-    const messageIndex = extractMessageIndex(lastSavedMessageId);
-    lastSavedSnapshot = lastSavedStateRoot;
-    // adding 1 to the message index to get the last saved count
-    lastSavedCount = messageIndex;
+    const lastSaved = await fetchLastSavedMessage(veaInboxAddress, chainId);
+    if (!lastSaved) {
+      lastSavedSnapshot = ZeroHash;
+      lastSavedCount = 0;
+    } else {
+      const messageIndex = extractMessageIndex(lastSaved.id);
+      lastSavedSnapshot = lastSaved.stateRoot;
+      // If the index is zero-based, keep as-is; otherwise, add +1.
+      lastSavedCount = messageIndex; // update comment accordingly if needed
+    }
   }

Confirm whether the graph’s message index is zero- or one-based so we can fix the comment or add +1 appropriately.

I need to verify the concerns raised in the review comment. Let me explore the codebase to understand the context.
