One of my favorite Mac apps, DiskWarrior, has been waiting for the APFS format documentation (also called the APFS volume specification) for a while, in order to make a new program version which can rebuild APFS disks. Recently, according their page linked above, this documentation was released and Alsoft is using it to update DiskWarrior. I would like to look at this documentation myself, as I find it interesting. However, I can't find the documentation anywhere. Do I need a certain Apple subscription to see this documentation or am I simply failing at googling for it? I've found a few documents like this, but I don't think that's what I'm looking for, since that document is not as comprehensive as what I would expect from a full volume format specification.

Almost all of the Mac developer documentation from Apple exists in several places. That being said, you want the unofficial Mac OS X Automation guide put together by Sal Soghoian. He also has a fabulous book on the iBook store titled AppleScript 1-2-3.
Xcode is the tool that links into these libraries and allows you to search across the various user guides, developer guides, language specifications, code examples and such.
Here is Xcode (with 10.6 and 10.7 documentation sets) and a quick AppleScript search.
Xcode makes it easier to bookmark, search and use the documentation rather than just browsing in Safari since it will download the whole
Of the 232 matches in the System Guides - about 10 cover AppleScript in depth - the rest refer to how programs make themselves available to be scripted by AppleScript.
Here is the OS X Yosemite v10.10 Documentation.
You can always find developer resources on the Apple Developer sites. You can find other OS X documentations there, as well as iOS documentations. Other resources, such as feature descriptions, revision histories, upcoming changes, and user agreements can be found there, also.
The best of luck in your programming endeavours!

I think Alsoft's use of the phrase APFS format documentation is just that - a phrase they've used rather than referencing an official title.
The Apple File System Reference is almost certainly what they're referring to. This reference was publicly released on 17 September 2018, and Alsoft made that statement on 4 October 2018.
Prior to the Apple File System Reference, there was no consolidated documentation from Apple regarding APFS - at least not to this level of detail. In fact, the most comprehensive documentation until this was released was actually the result of private academic work in the computer forensics field.
As for Apple itself, we've had the following documentation:
However, the Apple File System Reference was last updated in February 2019.
