to duplicate the appcast should be valid and report a needed update. the update should point to a unavailable file.
in the live case of this the file-not-found was compounded by a missing 404-page -- sort of a double 404. but the server had an automatic response for the missing 404 page. i suspect that plays an important role in this bug.
the update will complete without error or warning. even in the dev console. even with the .devstack extension.
the result is that the stack will "need updates" on each relaunch.
