I claim though that it it should be identical to the .deb file, because
I ran dpkg-scanpackages on it myself, and haven't updated anything
since (besides, if I had updated something, the MD5sum check would fail
wouldn't it?)

Packages entry:

What is different?

I wildly speculate that apt-get is making the assumption that package
version 1.1-11-2 will be exactly the same regardless of where it was
downloaded from, and is comparing the deb file against the Packages
entry from the unused/wrong source (priority==-1).
