thepraandClaude Opus 5.5 a5d493a8c9 Pasture: Friendica joins, in the scenarios and the town
Friendica 2026.05 on the shared MySQL and Redis, with its worker daemon as a sidecar. friendica_settle repairs what
its install leaves: the system user has no name, so the system account that signs its fetches is never made; the web
container cannot see the sidecar's daemon, so a queued job waits for the five-minute cron unless the daemon is
declared running; its log needs a file and debugging on. Accounts are saved through its API with locked=0 (a number:
"true" reads as 0, unlocked), which makes them soapbox pages that take followers without following back, and each
one's outbox is read once: a Follow that reaches an account Friendica has not cached makes it fetch the account from
itself, signed, and checking that signature recursed for five minutes, holding PrivaPub's first follow past its timeout.

scenarios/friendica.sh passes its 25 checks from a clean install: follows and unfollows, posts (a titled one with its
title), comments, likes, Friendica's dislike as a downvote, boosts, edits (through its web editor: its Mastodon API
never federates one) and deletes, both ways.

The town gets a Friendica driver (HTTP Basic, its MySQL read through mysql_json, edits in the web editor, no bookmark
on a reply) and specs/friendica-pair.json, which passes its 275 checks. On the way:
- the checker knows Friendica's thread model: a non-public reply reaches an account only under posts it holds, and a
  Friendica account's non-public reply in a thread another server owns reaches nobody else there;
- the seeder answers a follow request the target still holds whatever the follower's server says: Friendica reports a
  follow of someone already following its account as made at once (and shows that persona's followers-only posts
  while a locked persona still holds the request);
- the selftest skips polls where a platform has none; the shared MySQL helpers move to peers/shared.sh.

"""Replays a plan against the pasture and writes what happened to out/<run>/ledger.jsonl, one fact per line:
accounts made, groups made, follows and their state, objects with their URIs, interactions, mutations, errors.
A reply waits for its parent to arrive on the replier's server (the round before had time to settle); if it never
arrives the parent is fetched and the ledger says `arrived_by: fetch` for that server, so a delivery that failed shows
up as a cell in the report rather than as a broken thread. An error never stops the seeding: it is a ledger line."""
