While this is true, there is not really any need to go beyond
timestamp+size when determining if a file is modified or not.

So yes, you need to build an inventory of the tree, but you don't need to
read and compare each and every file in both the pristine and the working
tree, just the ones that dos not match the supposed inventory stored in
your metadata.

I notice the workingdirectory metadata (1.1) is missing signature data
such as expected modification time and size, but by just adding a little
signature data to the working directory you can quickly reduce what needs
to be looked at much in the same manner as CVS does which has been working
very well for ages. CVS only keeps modification time in the working
directory metadata for determining if a file is modified or not, but I
would recommend keeping size as well.
