This isn't and issue. It probably should belong in discussions which we do not have enabled. I have reposted from the CC-Tweaked's discussions as I many get more of a response from here.

I can do this in a Forge Architectury mod to include CC Tweaked

repositories {
    maven {
        url 'https://squiddev.cc/maven/'
        content {
            includeGroup 'org.squiddev'
        }
    }
}

dependencies {
    ...
    modImplementation "org.squiddev:cc-tweaked-${rootProject.minecraft_version}:${rootProject.cct_version}"
}

How what I would change to use CC-Restitched in my Fabric Architectury mod.
Also Architectury makes me need to use modImplementation instead of implementation fg.deobf(fabric gradle definition)

Also Architectury allows me to make my mod work on forge and fabric, by allowing to have a common code base between forge and fabric. But both forge and fabric needs to use specific libraries for the particular version.

https://github.com/Toad-Dev/cc-peripheral-test

This is the example mod made by ToadDev! all this shows is how to register a block as peripheral, defining lua functions for said peripheral, and how to register it to a turtle! (turtle example uses the block item it self to render on the turtle so keep that in mind)

Thank You
