There are some corrections that we have contacted the author about regarding the history of the project. They initially e-mailed us to ask a few questions but seems to have maybe misunderstood something.
For clarity, GrapheneOS is the continuation of CopperheadOS, not a new project that spun off from it.
As an example, it can be seen that our repositories and legacy bugtrackers are ours:
-https://github.com/GrapheneOS/platform_manifest/forks?includ...
-https://github.com/GrapheneOS/platform_bionic/forks?include=...
-https://github.com/GrapheneOS-Archive/legacy_bugtracker/issu...
It's a direct continuation, but was renamed to GrapheneOS post the failed takeover attempt. GrapheneOS has persevered and is all the stronger for it. Over a decade now. :)
