Smithereen joins the pasture (tools/pasture/peers/smithereen.sh): its image on the shared MySQL, with imgproxy and a file server behind Caddy, a JDK trust store with the pasture's CA, accounts from its signup form, and a password grant for a local application. scenarios/smithereen.sh drives its VKontakte-like API: friends as mutual follows, wall posts, comments, likes, reposts (quotes there), polls, edits, deletions, private messages, the unfollow and statistics, 30 checks. A post on someone else's wall never reaches PrivaPub, since Smithereen sends it only to servers whose actors publish a wall: G-0009, waiting for the owner. PrivaPub: a server description that failed (Smithereen serves no NodeInfo until it has a description) frees its week, so the server's next arrival asks again instead of a week later. The shared Postgres takes 400 connections: at 100 the village seed ran it dry (Sharkey's API answered 500, Misskey dropped deliveries). The seeder records a follow that stands from an earlier seed when the step itself fails, so the checker no longer expects that follower to see nothing.
