0o0100 (better 0o100, will fix), is a bit mask that, when applying bitwise AND (&) results
in a != 0 state whenever the file can be executed by the owner.
A perm can be seen as a 9-bit sequence mapping to rwxrwxrwx read-write-execute
for owner,group,everybody.
octal 0o100 means binary 001000000.
Probably better to set a constant and also add a comment

It previously was 0x0100 == binary 100000000. this was a bug, filtering in combinations where
the owner has read perms

Gotcha, would you mind adding a comment that explains this?

Do we need to error/log if the file isn't executable?

We don't want to error. This also happens on first install.
We are not going to error on first install, and we prefer to try to
recover if a previous install failed.
Probably we can add log for a failed previous install, while trying to recover.
