/home is a bind mount of /data/home: mv from /home to /data crosses mount
points, where the kernel refuses a rename, so mv would copy the whole
704 GB library with 147 GB free. Moving it by /data/home's path stays
within one mount.

The Jellyfin sidecar takes its library from a folder on the host where .env
names one (JELLYFIN_MEDIA, read-only), else from deploy/jellyfin/media as
before. On halkyon.li that is /data/media: the library moves out of the
developer's home, which Jellyfin's own user can't enter. The sidecar README
says how the home end's configuration, accounts and libraries move in, with
its network settings corrected for Caddy before it starts.
BREAKING CHANGE: compose.jellyfin-home.yaml, deploy/home-jellyfin/ and
jellyfin.caddy's JELLYFIN_UPSTREAM are gone with ADR 0032, whose server end
retires with learn.halkyon.eu's server; it was never brought up.

Meditate's deploy step (ADR 0038, step 7; ADR 0039, D14), as Todo's: the
server's Dockerfile with the library's check compiled beside it, its
production config on its own database and role, compose.meditate.yaml as a
member of the register, its site sending /library/* to the web server and
the rest to the API server, the operator's library read-only in a compose
file of its own, and redeploy.sh, backup.sh and the image replay taking it
in.
Every server's public address now comes from .env (Serverpod's
SERVERPOD_API_SERVER_PUBLIC_HOST and _WEB_SERVER_, which win over the
config file): Train, Todo and Meditate from their domains, Learn from
LEARN_PUBLIC_HOST, unset learn.halkyon.eu as before. Without it a server on
halkyon.li would name halkyon.eu in its SimpleLogin callback, profile pages
and privacy page.

Todo's locations search through the person's own instance, as Train's
planner does, not a public service: `SearchEndpoint` on `PlaceSearch`, for
those signed in, 60 searches a minute, nothing kept or logged. Its `Place`
carries the address's parts and the object in OpenStreetMap, and a shop's
car park or charger is left out, which came first for `Lindau EDEKA`.
`compose.todo-search.yaml` puts Todo's server on compose.search.yaml's
Photon. A file of its own: without it Todo starts as it did, and offers no
search.

No file has Compose's default name any more, so .env's COMPOSE_FILE is always set,
naming compose.learn.yaml first (.env.example sets it). compose.yaml stays as a link to
compose.learn.yaml for the one deploy that switches learn.halkyon.eu's .env over: the
deploy's merge runs with the COMPOSE_FILE from before. A later commit removes it.
BREAKING CHANGE: an instance's deploy/.env must set COMPOSE_FILE, starting with
compose.learn.yaml, before the link goes.

The folder kept its name from before the monorepo (ADR 0015), though
Train and Todo deploy from it too. redeploy.sh, the backup's units and
the operator's steps name ~deploy/halkyon; the Compose project keeps the
name halkyon-learn, as Docker names its volumes after it.
The server moves after this is deployed: the running redeploy.sh is read
whole before it runs, so the deploy of this commit still works in the
old folder; then the folder is moved, the pinned commands in deploy's
authorized_keys and the backup's units changed, and the containers
recreated on the new paths.

deploy/compose.todo.yaml adds Todo's server at todo.halkyon.eu, a member
of Learn's register, its database halkyon_todo in the instance's
PostgreSQL, its image built as Train's. redeploy.sh and backup.sh go over
every app server .env switches on (train, todo). Each compose file names
its server to the register in a variable of its own
(INSTANCE_MEMBER_TRAIN, INSTANCE_MEMBER_TODO), which halkyon_base adds to
INSTANCE_MEMBERS, each address once, as a second compose file's default
would have replaced Train's.
apps/todo/release.dart configures the release tool for Todo's APK and
snap: a key of its own (pinned once made; until then nothing is
released), the F-Droid listing (Time, NonFreeNet), and the snap from
apps/todo/snap/, which the tool builds in a clone of the repository at the
tag with that folder in place of snap/, as snapcraft builds one recipe a
folder and the root's is Learn's. What's new for 0.1.0 in English and
German, now shown. Android's backup and transfer are off, as Train's
(D53): the reminders scheduled keep their tasks' titles unsealed.

A workout with a track gets the weather over it as its page opens, once
while it has none: the hours from the one it started in to the one it
ended in, kept in its sealed payload (temperature, feels-like, humidity,
precipitation, the WMO code, the wind, its gusts and direction) and shown
under its totals with the link to Open-Meteo its licence asks for.
Train's server asks Open-Meteo in the person's place (the `weather`
endpoint), so Open-Meteo never sees their address: the place rounded to
two decimals (also on the phone), a span of at most 48 hours, the
forecast API for recent spans and the archive for older ones, for people
signed in, at most 30 requests a person a minute, nothing kept or
logged. On by default; `WEATHER=off` switches it off, and
`OPEN_METEO_API_KEY` moves it to the paid hosts for an instance used
commercially.
Health Connect's fingerprint leaves the weather out, so keeping it
writes nothing again. No table and no migration.

Run on the home end, the check that nothing new from the tunnel reaches
the instance's server failed at once with "missing port number" instead
of trying. OpenBSD's nc, as the WireGuard image has it, ends the try with

A tunnel that fails to come up takes Jellyfin's internet with it, as
linuxserver/wireguard's client mode deletes the default route. Named by
learn.halkyon.eu, the endpoint needed DNS to come up, which the home end
starting or waking hasn't always got yet; by its address the tunnel comes
up whatever the network does. Closes ADR 0032's open point.

linuxserver/wireguard's client mode deletes the default route when wg0.conf
fails to come up, so Jellyfin, in its namespace, loses TMDb and scans get
frames for posters. The README's step 4 says so and how to recover; ADR

The instance serves jellyfin.halkyon.eu and its Caddy proxies through a
WireGuard tunnel to a Jellyfin on the operator's own machine, which dials
out, so nothing names the home network's address and its router opens no
port. compose.jellyfin-home.yaml takes the sidecar's place, with its
site's rules unchanged (jellyfin.caddy's upstream is now a setting), and
leaves JELLYFIN_URL unset, so the instance suggests it only while it
answers.
On the instance's server the tunnel reaches Jellyfin from Caddy alone and
nothing of the host (wg-jellyfin-rules.sh, set and removed with the
tunnel); the CI runner's unit denies it, and CI's Sandbox step fails if a
job reaches it. The home end keeps Jellyfin in WireGuard's network
namespace, its port on the loopback alone. The steps are in
deploy/sidecars/README.md, the rules held by test/deploy/jellyfin_home_test.dart.

A failed BRouter segment or listing, a failed tile cut or an unwritable folder waited the whole refresh period, 30 days without routes or a map; they try again after an hour, doubling to a day. Photon's failed download backs off from a day to a week, and a dead Photon is noticed within a minute. The downloads' network is an ordinary bridge the three share, as the comments now say.

Protomaps' basemap cut for Europe and served by pmtiles beside Train's server
(compose.maps.yaml), drawn by Train's own style, light and dark, which the
server serves. Only people signed in get tiles: map.source hands a key that
Caddy has the server check before each tile; nothing logs a tile.
Also fixes .dockerignore, which left apps/train/ out of the build context, so

deploy/compose.train.yaml adds Train's server at train.halkyon.eu, a
member of Learn's register, with its database halkyon_train in the
instance's PostgreSQL, and BRouter beside it alone (v1.7.10, checked by
SHA-256, no log), its segments of the operator's region kept current
monthly. Nothing changes until deploy/.env names the compose file:
redeploy.sh and backup.sh take Train in only then, and the operator's

Step 1 of both sidecars changed into deploy's home before its sudo
commands, but Ubuntu closes a home to other users, so the operator's
own user, the one with sudo, gets "Permission denied" there (found
setting up LanguageTool on learn.halkyon.eu's server, 26 Oct). sudo
reaches the folders by their full paths, which the shell makes of
~deploy without entering it.

no published port, as user 61081 on a read-only filesystem, without a
log. The server alone reaches it (LANGUAGETOOL_URL): grammar.check is
for those signed in, takes 20,000 characters, 60 checks a minute each

and keeps nothing. instance.info() names the languages it checks; the

Caddy's network had IPv4 alone, so Docker's userland proxy forwarded
every IPv6 visitor to Caddy from the network's gateway, and the server
counted all of them as one network (the second reading's M5, reasoned).
The edge network gets a unique local /64 (fd4a:6c6b:7e80::/64), Caddy a
fixed address in it beside its IPv4 one, both trusted as the proxy; the
CI runner's unit denies fd00::/8 and its sandbox check tries Caddy's IPv6
address too. A commit of its own: it needs Docker 27 or later with
ip6tables on the server and the network made anew (compose down, never
-v, then up), checked by hand first (NEXT.md).

The sidecar's steps made Jellyfin's user with its own group, to which
useradd gave a system group ID (987 on learn.halkyon.eu's server), while
compose.jellyfin.yaml runs it as 61096:61096. The group is now made
first with the same ID, and the steps say why useradd's warning about an
ID above the system range is meant.

An instance may now run services beside itself, each a compose file of
its own switched on in deploy/.env (COMPOSE_FILE=compose.yaml:compose.
jellyfin.yaml), so the deploy runs them with the instance. The first is
Jellyfin, which people watch and listen to learn from: the instance then
suggests it (JELLYFIN_URL from JELLYFIN_DOMAIN), and Caddy serves its
site, refusing every change to a user from outside, so a passwordless
demo account stays everyone's; its admin signs in through an SSH tunnel.
The instance's compose gets a second network, `edge`, for Caddy (at a
fixed address, which sidecars trust as their proxy) and the server;
Postgres stays on the internal one. Caddy loses its needless way to
Postgres, and a sidecar never gains one. A sidecar publishes no port,
as the CI runner may reach 127.0.0.1, and runs as a user ID of its own.
Caddy imports the sidecars' sites from sidecars/, mounted by their
compose files (none without), and redeploy.sh recreates it when one
changes. sidecars/README.md has the steps.
