Files called the servers by their own host names, which are the
operator's and say nothing a reader needs. They now say which domain a
server serves: learn.halkyon.eu's server (the instance and its CI
runner), the halkyon.app server (Forgejo and the F-Droid repository).
Two names are settings rather than words. CI's runner label becomes
`instance` (`runs-on: instance`, `labels: ["instance:host"]`): the
runner reads its installed copy of deploy/runner/config.yml, so jobs
wait in the queue until that copy is updated and the runner restarted.
The SSH aliases the scripts and docs use become `learn-deploy` and
`fdroid-upload`. AGENTS.md says to keep it so.

A person with an identity and a public profile publishes a studyset with
everything inside it as its next release (ADR 0005, rule 3): the server
reads their synced rows and writes them through the git command as a
commit on main and the annotated tag vN, in a bare repository of the
studyset's own, named by a random public id made at the first publish.
A release is a directory per studyset with a file per card, note, path,
step and PDF (its id, position, tag names and payload as synced, keys
sorted and indented) and the files the content names, without what is
only the author's (a card's report, a PDF's deadline). Publishing is
refused without a licence allowing passing it on in every studyset ("no
derivatives" allowed), with revisions to settle, with files not uploaded
yet, when nothing changed, or for a name that won't do; the name is
fixed from the first release, as is the person's handle.
In the app, Share in a studyset's action row opens the Publish sheet;
publishing syncs first, and settles by itself the revisions that merge
cleanly, listing only real conflicts. The server's image gets git, the
repositories a volume of their own, and the hourly backup a git bundle of
each.

learn.halkyon.eu dumps its database every hour (people's files are in it
too) and restic stores the dump encrypted in a Hetzner Storage Box,
keeping 24 hourly, 7 daily, 4 weekly and 3 monthly snapshots. The box's
own snapshots, removable only in Hetzner's Console, protect the backups
from a taken-over server. A systemd timer runs it as deploy; once a day
it also prunes and checks the repository. Failures go to the journal.
Hourly, because a restore costs people who started after the backup
what their device held: the app no longer finds its session and starts
anew. deploy/backups.md describes the setup, the restore and what a
restore loses; both were rehearsed on the local Compose stack.
