• The reference to ethereum.NotFound in BuildPreconfBlock is no longer resolved since the import of github.com/ethereum/go-ethereum was removed. Reintroduce the correct package import or update the error check to use an available error constant.

-	"github.com/ethereum/go-ethereum"

packages/taiko-client/driver/preconf_blocks/api.go:269

• Ensure any OpenAPI/Swagger specification or external documentation is updated to remove the DELETE /preconfBlocks operation so docs remain in sync with code.

-// RemovePreconfBlocksRequestBody represents a request body when resetting the backend

packages/taiko-client/driver/driver_test.go:429

• After removing all references to RemovePreconfBlocksRequestBody, verify and remove any unused imports (e.g., the preconfblocks package) to avoid compilation errors in tests.

-	// Remove one preconfirmation block
