Loose expander -> carefully observe position of expander, then tighten top cap (with the additional spacers installed). Then disassemble everything again to see whether the expander moved.
Steerer tube too long -> if the issue with the headset play doesn't return with the additional spacers installed (and you have ruled out the expander), you know your steerer tube needs shortening.
Bearing play -> unlikely, I suspect you'd be able to feel that just by handling the bearings.
And yes, the clamped stem is what's meant to keep the headset compressed; the top cap is only intended for the initial bearing pre-load.
Regarding your question about the shim, you'll need shims if your bearing cover bottoms out against the frame; you want the cover to float just above the headtube. The shim(s) would sit between the compression ring and the cover.
Thank you, this was very helpful!
I got a spacer at a nearby shop and used the cap which was thankfully also provided by velobuild.
I think it has fixed the problem for the most part for now.
Its not pretty, but not ugly enough for me to redo the bleeding of the breakes - classic case of "whatever, Il leave it like that for now".
I still dont fully get the shim thing but maybe thats a topic to look into some other time.
