Change Index.arch to the type (Arch of string | GuessedArch of string). In a future commit, the index parser will allow arch not to be set for some cases. Thus arch value will be guessed by inspecting the image. However we need to distinguish between a set value and a guessed one. Using this new type will help it:...
