To be clear: I use upgradeSeasideImage *only* to load 1.0-beta.9.1, and
not our own application or its dependencies (Seaside, Zinc, etc.) This
is because we have upgraded to a lot of dependencies published on github
as filetree repositories, and upgradeSeasideImage can't handle that, as
mentioned earlier on this thread.
So my aim was for upgradeSeasideImage to get the repository similar
enough to extent0.seaside.dbf that we can just invoke the exact same
scripts that work against that to load the newer GLASS (as published on
github) and all our other dependencies.
It is during this process that the error occurs, and the methods all
just seem to disappear after topaz dumps a stack trace that makes it
very clear that the methods did exist at the point of error.

No, all I set was BootstrapApplicationLoadSpecs to load GLASS 1.0-beta.9
and then GLASS 1.0-beta.9.1 as you suggested earlier in this thread.

Yes, as mentioned, the error occurs *after* a normal upgradeSeasideImage

The exact same code base, loaded onto a 3.1 extent0.seaside.dbf by the
exact same scripts I run after upgradeSeasideImage, passes all unit
tests in that "clean slate" scenario.

Only GLASS-related method source is visible. All other classes are still
in their "removeAllMethods" state as upgradeSeasideImage made them; the
hope was that by running our code loading script the rest of all the
methods would also be loaded.
What I take from your message is that I need a suitable
MCPerformPostloadNotification handler to suppress #initialize methods;
and that the session method machinery is a likely explanation for why
the methods seem to disappear - if that persists I should look at what
upgradeSeasideImage did in that regard and run our scripts in the same
type of context. These are good leads, thank you.
