- PersonaSeparationTests: two personas of one login follow the same account and post; nothing the API maps for one contains the other's id, username or the root id. - tools/smoke/mastodon-api.sh checks what a client meets first (instance v1/v2, discovery, app registration, client credentials, an app token refused by a user endpoint, the public timeline, revocation) and, given a persona token, verify_credentials, home and notifications. deploy.yml runs it after every deploy. - OAuthPruner removes invalid tokens and authorizations older than two weeks, every six hours. - The consent page no longer sets form-action, which browsers apply to the redirect back to the client after the form is posted.
