But some parts are far from being trivial engineering and are not part of any specs. Just consider the security infrastructure (multiprocess, sandboxing etc.) and how that impacts the overall design of the engine itself.
The e/OS/ CEO said during an interview [1] that GrapheneOS, being a security hardened product, was especially useful for p*ophiles to evade justice. This is totally unacceptable. People defending e/OS/ (and Murena, same people, just branding for devices) are either dishonest or useful idiots.
If you can, try again (don't forget to start with `./mach bootstrap` to install dependencies) and open an issue if the build fails. SpiderMonkey is shipped pre-compiled for most architectures, so it's not a big hurdle in terms of build time.
