check / check (push) Failing after 2s
mfer gen now writes index.mf instead of .index.mf, the name fetch requests and the README calls the standard filename. Given a directory, check, freshen, list and export look only for index.mf; .index.mf is no longer recognized. Because index.mf is not hidden, gen and freshen now leave the manifest they write out of its own listing by file identity (os.SameFile), so it is recognized however its path is spelled, through a symlink included, while an ordinary file of the same name elsewhere in the tree is still listed. Model: opus-5-5
