OpenRoots and Proprietary license
Possible only with clean rights and clear separation. The proprietary licence cannot overwrite OpenRoots terms.
Inbound
conditionalProprietary material entering an OpenRoots work
Proprietary material can enter an OpenRoots work only if the proprietary owner grants rights broad enough to redistribute it under the OpenRoots instrument. Without that express permission, inbound use is no.
Outbound
conditionalOpenRoots material entering a Proprietary project
An OpenRoots work can be distributed inside a proprietary product only if the OpenRoots terms remain intact for the OpenRoots portion. The proprietary licence cannot erase the royalty, AI training, notice, attribution, no-fallback, or competing-offering terms.
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.Merging proprietary and OpenRoots code requires a rights audit. If the proprietary owner controls both sides, dual licensing may solve it; otherwise the default answer is no.
Composite distribution
Both shipped side by side, not merged.Composite distribution is often possible when the OpenRoots component is separable, notices are preserved, and the proprietary EULA does not purport to supersede OpenRoots permissions.
Patent position
Express grants and termination triggers.A proprietary licence may contain patent terms, field limits, or no patent grant at all. Compare those terms with the OpenRoots patent peace clause before shipping a combined artifact.
The royalty
Where the Canopy obligation bites.The OpenRoots royalty continues to attach to the OpenRoots portion for Canopy Licensees. A proprietary licence fee does not satisfy that obligation unless the licensor says so in a public waiver or approved payment mechanism.
Current permanent terms
What holds for as long as the release exists.No automatic conversion occurs. Proprietary restrictions govern only the proprietary portion, and OpenRoots terms govern the OpenRoots portion.
