Validation: the dump validators refuse the nulls their shared types don't allow (a null title or note on creation, a null URL on edit); a playlist title of spaces is refused and titles are stored trimmed; usernames and emails are checked by the same USERNAME_RE and EMAIL_RE in shared/validation.ts on sign-up, on PATCH /api/users/me (which checked other limits) and in the sign-up form. Mentions are read by shared/mention.ts's mentionedUsernames, which skips code and URLs as Markdown shows them: https://mastodon.social/@bob or a `@bob` in code notified bob; the editor's suggestions derive their trigger from the same pattern instead of a copy. Following an unknown user is a 404 rather than a foreign-key 500, and following a private playlist a 404 rather than a 403 that confirmed it exists. `ws` and `emojibase` are reserved category slugs, since the server answers them before the app. GET /api/users/me no longer turns every error into a 500. Dead code goes: adminOnlyMiddleware, verifyEmailTransport, listUsers, deleteUser with disconnectUser and the force_logout message only it sent, PATCH /api/notifications/:id/read (with markOneRead), isSlugAvailable, the unreachable 500 in fetchComment, and the `if (!ctx.state.user)` checks behind authMiddleware. 214 backend and 627 frontend tests pass.
