providers

v4: link previews are read once, in one place, and no longer take an error page, a relative image or a mask icon for the page's — each provider fetched its page and scanned it with regular expressions of its own, the generic one some fifteen times, and Bandcamp and SoundCloud read only OG tags. fetchPage (remote/fetch.ts) now fetches every page, follows redirects to the address it was served from, and refuses an error status, so a 404 or a bot challenge is unreachable rather than a preview titled "Just a moment...", and a refresh no longer overwrites good metadata with it. parsePage (remote/html.ts) reads it in one linear pass with a real attribute reader: unquoted values, a > inside quotes, og: tags under name as well as property, and nothing from comments or scripts. Every URL a page names is resolved against where it was served from, so a relative og:image works; entities are decoded in one pass, é and ’ included, and one that names no character no longer fails the preview (bandcamp-tralbum.ts shares the decoder). The mask icon is no longer the favicon, JSON-LD prefers the page's node over the site's, tracking pixels and lazy placeholders aren't thumbnails, an og:url with a slug keeps the OG tags, and a <title> loses its site suffix. genericPreview is the base of the Bandcamp, SoundCloud and YouTube channel previews; SoundCloud takes www., m. and on.soundcloud.com short links, embedding the page they lead to, and Bandcamp keeps only its own player. The service tidies every preview: text on one line, titles and descriptions capped, only http(s) images and players. RichContent.type is now RichContentType, and the unused videoId is gone.

bandcamp-streams.ts

v4: what the server and the client both state is declared once — several rules were written out in two or more files, some already drifting apart. A link's site name (its host without www.) was computed in five places, now shared/url.ts's siteHost; dumpFileVersion, which the frontend and the server had to keep equal by hand, is one function in shared/dump.ts; the Markdown flattening of the chat's reply previews and the digest's quotes is shared/markdown.ts's markdownToPlainText, so the digest also keeps an image's alt text; an attachment's URL and how to find one in a text are shared/attachment.ts, which the editor, Markdown and attachment-service read, its id pattern the new UUID_RE that the file and thumbnail routes check ids with. On the server, the Bandcamp, YouTube playlist and link preview caches use one TtlCache (api/lib/ttl-cache.ts) instead of three copies of the same expiry and eviction; the link previews' theme-color and the emails' theme tokens read colours with one parser (api/lib/css-color.ts), and a transparent theme-color now gives no tint; the WebSocket route sends through ws-service's send, the welcome included, so it is type-checked; fetch.ts strips an IPv6 literal's brackets with public-address's bareHostname; and a category's slug is checked by the same validateSlug as a dump's, with its own length. The migrations keep their frozen copies, as they document. 272 backend tests and 677 frontend tests pass, and deno check, tsc, eslint and doc:lint are clean.

gerbeur-instance.ts

v4: an instance can be named by the address of its pages — sign-in and the trust list took only an instance's issuer, its API's origin, so where the pages live elsewhere the address people see in their browser named no instance: in development, localhost:3000 answered its /.well-known with index.html, and the sign-in failed as "doesn't answer as a gerbeur". resolveIssuer (remote/gerbeur-instance.ts) now reads the metadata at the address given and, when it names another issuer, takes it only if that issuer's own metadata names those pages back as where its /authorize is, so an impostor can't claim one; sign-in, the trust list and the check against this instance go through it. The Vite dev server passes /.well-known on to its API, as whatever serves the pages must in production (README). A handle still carries the API's host.

html.ts

v4: ESLint and deno fmt pass on the whole tree again — html.ts's attribute pattern escaped a "/" its character class doesn't need escaped (no-useless-escape), and a line of journalLayout.test.ts ran past the width.

image-proxy.ts

v4: a still is scaled from its first frame alone, a second image in its file made the copy flash — an avatar came out as a WebP of two frames looping at 40 ms each, the picture then a blank. A still's file may hold more than one image, a phone's JPEG carrying a gain map or a depth map after the photo, and ffmpeg reads each as a frame: only the JPEG and PNG copies were held to one, the WebP keeping them all as it does a GIF's. scalableImage (lib/upload.ts) now says whether the image is an animation, which a GIF alone is, and scaleImage (lib/ffmpeg.ts) writes one frame of anything else, in every format; the image proxy scales through the same call. The copies already made stay, a copy being current while it has its upload's date: uploads/scaled is to be deleted once on an instance that ran the previous version, everything in it being made again on first request.

public-address.ts

v4: what the server and the client both state is declared once — several rules were written out in two or more files, some already drifting apart. A link's site name (its host without www.) was computed in five places, now shared/url.ts's siteHost; dumpFileVersion, which the frontend and the server had to keep equal by hand, is one function in shared/dump.ts; the Markdown flattening of the chat's reply previews and the digest's quotes is shared/markdown.ts's markdownToPlainText, so the digest also keeps an image's alt text; an attachment's URL and how to find one in a text are shared/attachment.ts, which the editor, Markdown and attachment-service read, its id pattern the new UUID_RE that the file and thumbnail routes check ids with. On the server, the Bandcamp, YouTube playlist and link preview caches use one TtlCache (api/lib/ttl-cache.ts) instead of three copies of the same expiry and eviction; the link previews' theme-color and the emails' theme tokens read colours with one parser (api/lib/css-color.ts), and a transparent theme-color now gives no tint; the WebSocket route sends through ws-service's send, the welcome included, so it is type-checked; fetch.ts strips an IPv6 literal's brackets with public-address's bareHostname; and a category's slug is checked by the same validateSlug as a dump's, with its own length.

twemoji.ts

v3: fix the backend's correctness findings — each by a rule shared across the code rather than one more special case. Link previews: readTextCapped decoded every page as UTF-8, so a Latin-1 page came out garbled unless it went through the curl fallback, which re-encoded it on its own; pages are now decoded in the charset their Content-Type or <meta> declares, and the curl fallback hands the bytes over as they are. The image proxy served and cached for a day an error answer that claimed an image type, and read a body without Content-Length whole before checking its size; it now refuses an error status and reads through the same capped reader. The icons task's Twemoji fetch gives up after 15 s instead of holding the start up, and extractLinkHref, which only its tests used, is gone. Backlinks matched a linked URL against the raw url column, so https://x.com/ missed a dump posted as https://x.com ; they now compare canonical URLs, as reposts do. The four LIKE searches put the query in raw, so % and _ were wildcards and the mention search for "a_b" found "axb"; lib/like.ts escapes them. Every list query now treats a malformed row the same way, a 500 through model/rows.ts's parseRows, where ten of them silently dropped it; the playlist dumps query uses the model's column list rather than a hand-written copy, and the aliased list is derived from the plain one. The vote and like services commit through transaction() instead of their own BEGIN and ROLLBACK, which would have rolled back a caller's transaction.
