A backup is a directory <stamp>-<kind> under Backups:Root (/var/lib/privapub/backups, 2770, files 0640), written as
.partial and renamed once whole: a manifest (host, build, newest migration, each collection's count, size, sha256 and
indexes, what was left out and why, the media list), each collection as gzipped canonical Extended JSON read raw, and
hard links to the files of untrashed media rows (copies where a link can't be made). On a replica set every collection
is read in one snapshot session. Never in a backup: the statistics salt, jobs, recovery codes, sessions, the
maintenance lock and the configuration's copy with its SMTP password.
One backup or restore at a time (MaintenanceLock, a heartbeat document), and the janitor purges nothing meanwhile.
BackupScheduler backs up nightly at 03:30 UTC (or at once after missing a night); rotation keeps 7 daily, 4 weekly,
3 pre-deploy and 3 pre-restore backups. CLI: admin backup [--kind] [--db-only], admin backups, admin backup verify;
these run before migrations, so the deploy's own pre-deploy backup, which replaces mongodump, is of the database as the
live build left it. EntityMaps.Warm runs once under a lock, since test hosts now boot side by side.

Deleting a post, editing media out, replacing an avatar or a header, and removing a whole root deleted no file: every
one stayed on disk and publicly served from /media/files with a year-long immutable cache, its row orphaned. Now every
upload is a row, profile pictures too (Kind avatar or header, ProfileOfAvatarId), and each of those acts trashes what
it held, as does an upload never posted for a day and a dropped scheduled post. A trashed row is marked in one
conditional update (an upload attached meanwhile is left alone), its files move into media-trash, beside the media
root and outside what /media/files serves, and the janitor deletes them a day later. Nothing is deleted for looking
unused.
Along the way: a profile picture that isn't an image, or can't be read, answers 422 instead of being silently ignored
with a 200; a removed root's scheduled posts are dropped, so nothing of it publishes later; media rows get indexes
(they had none), and the janitor's first pass comes five minutes after boot instead of an hour.
`PrivaPub admin media audit [--fix]` compares the disk with the database. With --fix (as www-data) it gives the
pictures personas show today a row, and trashes media of deleted posts or personas, rows whose files are missing, and
files nothing holds: the leftovers of every deletion until now. MediaLifecycleTests covers each act, that the trash is
never served, and the audit.

Owner decisions (2026-10-04, recorded in docs/ROADMAP.md): production runs everything that is built, and nothing waits
on a person running a command.
- Geolocation updates itself. GeoUpdater, a hosted service, checks daily whether each DB-IP Lite database was built this
month. If not, it fetches this month's, or last month's early in the month. It installs a file only once it opens as
the right kind of database, then swaps it in atomically, and the locator reloads at once. Lookups now run under the
lock, so a reload can no longer dispose a reader mid-lookup. The systemd timer, its script and their setup.sh lines
are gone: the root step they needed never happened, and none is needed now. /stargazing names the database in use.
- The admin CLI runs after the app is built, with every service and nothing started.
- `create-root <login> [--admin]` takes the password on stdin; it is how the first login is made while sign-up is
closed.
- `smoke <persona>` keeps the root `deploy-smoke` and an undiscoverable persona, and gives the root a new password
on every run.
- The deploy signs in as @thepra. It runs the CLI, gets a token through the real OAuth flow (tools/smoke/oauth.sh,
moved out of the pasture's privapub_token, which now uses it), checks the signed-in API and that @thepra is
undiscoverable, then revokes the token. PRIVAPUB_SMOKE_TOKEN is gone.
- The deploy also fails when:
- NodeInfo and the instance API disagree about registrations;
- /stargazing does not say the crawler is on;
- the geolocation databases are missing or more than 40 days old.
- The crawler is on in production, seeded with ten large servers of different kinds. FEDERATION.md now describes it
and how to opt out.
- One registrations switch (Registrations:Mode, default Invitations; Open in tests and the pasture). It is read by
open sign-up (403 when closed), NodeInfo `openRegistrations`, and v1 and v2 of the instance API, so they can no longer
disagree. Before, NodeInfo said open and the instance API said closed. Group invitations always work, so
invites_enabled is true.
- A persona edit through /clientapi no longer resets what the Mastodon API set (discoverable, locked, quote policy…):
the theme is merged into the settings instead of replacing them.
650 tests pass. The deploy's smoke step was rehearsed against the pasture's PrivaPub.

S14 and the privacy items of P0:
- signing up as "admin" no longer grants admin; `PrivaPub admin promote
<root>` (and `demote`) does, run on the box against the configured
database;
- Swagger is served in Development only;
- every service and controller answers "Something went wrong." where it
used to send ex.Message, and the SMTP warnings no longer log the
recipient's address;
- sign-up and login no longer log the IP, User-Agent and root id together;
- invitation sign-up takes the persona's own AvatarUserName (and optional
AvatarName) instead of naming the avatar after the private login, and
refuses a persona username equal to the login's. Invitation login uses
the named persona, creating it if it is new;
- recovery mail comes from "PrivaPub", not collAnon's support address name.
