Am interested in the ability to pin some packages in Tanglu.
In debian, testing & unstable are added to the sources.list. Can this be done in Tanglu? Are there static names for Tanglu "testing" & "unstable"?


Afaik it is a bit simplified. Packages from testing and a few from unstable and experimental used for the actual development version (Dasyatis). So there already almost actual packages in the development release. This is one option.
If you are brave enough you could use the staging repo for pinning. There you will find always the most recent version of packages independent which is the actual devel version. But be aware this could cause trouble.
