I agree with the comments about the too wide topics that probably are
better to not be covered in a single book.

I also want to point to C++ Premier (5th edition) by Lippman as a very good
book IMHO. It doesn't assume any background in C++, C or programming, and
it teaches modern C++ (C++11) in a very natural way. Upgrading later to
C++14/17 should be easier task. (C++20 - will see...). This book may help
to cover "learning programming" and "learning C++" targets, and then you
have to fill only the "learning game development" point.

Another point I'd like to comment about:

> start with the CPU and work upwards: registers and the program counter,
objects, functions and function templates, classes and class templates,
modules and libraries

I'm sorry, but from my experience in teaching (which is probably inferior
to yours), this seems to be the wrong approach, especially with beginners.
It may work with more experienced audience, but even there I'd be more
skeptic about such an approach.
Anyway, if you think this is a good idea, maybe you want to give a look at
nand2tetris project to see their approach for giving students a perspective
on how things work from the lowest level building up until reaching a
high-level language.

For sg20 minutes, I'm not sure if there is one place were they are all
found (I'm not sure if they all even presented as papers in mailing). I
guess the only way is to search the archives here for "telecon minutes".

Last but not least, I'd like to mention the relevant sg20 papers:
P1389 - Standing Document for SG20: Guidelines for Teaching C++ to Beginners
P1725 - Modular Topic Design
