Summary of Changes

Hello @luohewuyang, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refining the clarity and precision of existing code comments across two files. It addresses minor grammatical and wording inconsistencies to ensure that the inline documentation accurately conveys the intended meaning, thereby enhancing code readability and maintainability for future developers.

Highlights

• Comment Clarity in submitter.go: Corrected a minor grammatical error in a comment within block/internal/submitting/submitter.go to improve its clarity regarding execution client errors.
• Comment Wording in signed_header.go: Improved the wording and grammar in a comment in types/signed_header.go, changing 'basic validator' to 'basic validation' and 'granted data' to 'given data' for better readability.

Code Review

This pull request aims to improve code comments. The change in types/signed_header.go is a good step towards better clarity. I've provided a suggestion to further refine the comment for conciseness and consistency. I also noticed significant code duplication between ValidateBasic and ValidateBasicWithData and recommend refactoring to improve maintainability. The change in block/internal/submitting/submitter.go appears to be a formatting-only change with no functional impact, so I have no feedback there.

[gemini-code-assist]

While this change improves the grammar, the comment could be more concise and align better with the comment for ValidateBasic. ValidateBasic is documented as being for an aggregator node. This function appears to be for a sync node. A more direct comment would be clearer.

Suggested change

	// ValidateBasicWithData performs basic validation of a signed header, given data for syncing node.
	// ValidateBasicWithData performs basic validation of a signed header for a sync node.

[gemini-code-assist]

This function ValidateBasicWithData shares a significant amount of code with ValidateBasic (lines 110-186). This duplication makes the code harder to maintain, as bug fixes or logic changes need to be applied in both places.

To improve maintainability, consider refactoring the common validation logic into a private helper function. The differences, like the signature provider (aggregatorSignatureProvider vs. syncNodeSignatureBytesProvider), could be handled by passing a function as an argument to the new helper.
