'svnadmin recover' in FSFS recreates 'current', and maybe a few other
things, but it most definitely doesn't fix broken svndiff deltas. (How
would it do so? The filesystem may not have the redundant storage from
which to reconstruct them...)

That's the interesting part. It tells you that the representation
(either the full plaintext or a binary delta) which starts at byte 325
of the r2 revision file is corrupt. You can continue by looking at that
offset of that revision and see what bytes you find there. ('xxd -s 325
-l 488 /path/to/revs/0/2' for example.)
A representation header is either "PLAIN\n" or "DELTA\n" or "DELTA $some
$numeric $parameters\n". A representation terminates in the word
"ENDREP\n". The representation's length (excluding header and trailer)
should be 387 bytes. Details in the file subversion/libsvn_fs_fs/structure
in the source tree.
Here's an example:
SVN[9 chars]This is the file 'iota'.
