ShareAlike requires that adaptations be licensed under the same or a compatible licence. An OpenRoots instrument is neither, so BY-SA material cannot be adapted into an OpenRoots work.
Outbound
noOpenRoots material entering a CC-BY-SA-4.0 project
The royalty obligation is a restriction BY-SA does not permit on an adaptation.
Mechanism
Where the pairing holds and where it breaks.
A matrix cell tells you the answer. These are the clauses that produce it.
Derivative works
One combined, distributable artifact.Not permissible under current terms.
Composite distribution
Both shipped side by side, not merged.Collection use is permitted by BY-SA: a BY-SA work included unmodified in a collection does not force the collection under BY-SA. That is the only safe pattern.
Patent position
Express grants and termination triggers.No patent grant on the CC side. OpenRoots patent terms govern only the OpenRoots portion.
The royalty
Where the Canopy obligation bites.Incompatible with ShareAlike for adaptations.
Current permanent terms
What holds for as long as the release exists.No automatic conversion occurs, and the incompatibility for adaptations remains.
