Is the AOSP documentation source markup publicly available?

Occasionally, I want to reference topics like https://source.android.com/docs/core/architecture and https://developer.android.com/guide/topics/permissions/overview . However, because their content changes, referring back to them without saving them in their entirety (via archivers like https://web.archive.org/ , or extensions like [SingleFile](https://github.com/gildas-lormeau/SingleFile/releases/tag/v1.2.0) and its myriad competitors) can be difficult. Were I to be able to access its source markup stored on a version control system like git (I can't imagine they use SVN) I would be able to refernece versioned documentation, like I can at https://android.googlesource.com/platform/frameworks/base/+/a48127f0276e1fb4e309776b4216160fd5b67e56/core/java/android/os/Users.md#user . Consequently, is the documentation source rendered at the aforementioned URIs publicly available, like the referenced android.googlesource.com markup is? I ask because Microsoft provides this at https://github.com/MicrosoftDocs , so I would be surprised if Google didn't. However, I've been unable to locate it.
