LGTM, +1 on 0001

Some more comments on 0002:

We have not yet scanned the pages, so I suggest plan/scan_pages_eager
and *_lazy as variable names instead, to minimize confusion about the
naming.

I'll await the next iteration of 0002 in which you've completed more
TODOs before I'll dig deeper into that patch.
