Changes Summary

This PR makes targeted improvements to error handling in the check_access_list function while cleaning up unused error variants:

1. Error Cleanup (crates/supervisor/core/src/error.rs): Removed unused InteropNotEnabled and InteropValidationError variants
2. Enhanced Error Mapping (crates/supervisor/core/src/supervisor.rs): Added proper error conversion for critical operations

Positive Aspects

• Clean Error Handling: The new .map_err() calls properly convert errors to spec-compliant SuperchainDAError::ConflictingData
• Better Debugging: Added structured logging with error context for failed operations
• Code Cleanup: Removing unused error variants reduces code complexity
• Consistent Error Mapping: Both operations now follow the same error handling pattern

Code Quality Assessment

🟢 Good Practices:

• Proper error logging with contextual information (%err, %initiating_chain_id)
• Consistent use of map_err() for error transformation
• Following Rust idioms for error handling
• Maintaining backward compatibility in RPC responses

🟡 Minor Considerations:

1. Error Context: Lines 312 and 334 in supervisor.rs:312,334 - Consider if ConflictingData is the most appropriate error type for all validation failures
2. Import Cleanup: The removed use kona_interop::InteropValidationError; import should be verified across the codebase

Potential Issues

🟢 No Critical Issues Found

The changes appear safe and well-targeted:

• No breaking API changes
• Maintains existing error handling semantics
• Proper error logging added

Security Assessment

🟢 Security: Good

• Error messages don't leak sensitive information
• Validation logic remains intact
• No new attack vectors introduced

Performance Impact

🟢 Performance: Neutral/Positive

• Minimal overhead from additional error mapping
• Reduced enum size from removing unused variants
• Improved debugging efficiency through better logging

Test Coverage Recommendations

While I cannot see specific test files for check_access_list, consider:

1. Testing error scenarios for validate_interop_timestamps()
2. Testing error scenarios for verify_checksum()
3. Verifying that errors are properly mapped to ConflictingData

Suggestions for Future

1. Consider adding more specific error types for different validation failures
2. Document the error mapping decisions in the code comments
3. Ensure all files importing removed error variants are updated

---

Overall Assessment: ✅ APPROVED

This is a solid improvement that enhances error handling robustness while cleaning up unused code. The changes are focused, well-implemented, and maintain backward compatibility.

Does it require to be error log as this is user/caller error

[dhyaniarun1993]

Thank you for pointing that out.
Nope. It should be debug/warn. I will fix it in a separate PR
