The first thing I do on my base container is use WithEnvVariable to set MAKEFLAGS. I’m expecting that will cause that environment variable to be set in every subsequent call to WithExec.
Is that expectation correct?

Yes, that's right.

Cool! Experimentally, it didn’t look like it was getting set, so I’ll try to debug. Maybe there is some caching in the way.

OK, I added some debugging and I'm calling (*Container) EnvVariable(..., "MAKEFLAGS") before each exec make, and it's never set.

You mean WithEnvVariable? Can you show a simple example?

IIUC EnvVariable fetches an environment variable from the container.
I can't share code, but I'm doing this:
builder := base.WithEnvVariable("MAKEFLAGS", "-j8").
With(func(...) { return buildThingA(...) }.
With(func(...) { return buildThingB(...) }
And in the nested container funcs, I don't see a value for MAKEFLAGS
dim vector
Sorry, need to see more. You don't need to share, just if you can make a small example where I can run and confirm the same result.
Try adding a cache busting var to confirm if it's cache related: https://docs.dagger.io/cookbook#invalidate-cache

no worries; if I have tiime I'll try to make an example

It was a bug in my code. I was had a With() that was capturing the container from the outer function rather than using the parameter.
