Scripts reported as not found in imported package

A bit of a puzzler in here.
Created a package, exported it, imported it.
The package has a prefab and instantiating the prefab all scripts appear to be there, but reported as missing:

(the texture_put script is the last one in the folder, and a preview shows the contents being there too)
Happens across several Unity versions. Meta files and the rest are there, what am I missing?

thanks!

edit: checked the meta ID of the meta of one of the "missing" scripts againt the one referred to by the prefab file, they match, who gives? View attachment 439610

 

It was an error on my side where Unity has a relatively obscure way to complain.
So, following the recomended layout: https://docs.unity3d.com/Manual/cus-layout.html
there's a mention of assembly definitions, you do need those, or this error happens.

@unitydevs: how come we need that for packages and not for local code? you'd hope that local code that contains the right stuff to deal with platforms -locally- and so on will be enough

 

Yeah, it makes sense (might have been name collisions among packages or something), probably also makes sense to auto-namespace the incoming code, but 'tis all good, thanks for the answer!
