Containers are created with `--rm`, so Docker removes them asynchronously after they stop.
The pre-start `docker rm` returns immediately while that removal is still in progress
(its error is suppressed), and the following `docker create --name` can fail with
"The container name ... is already in use".
This is easy to hit since systemd_service_manager switched its default restart mode to `all-at-once`:
many containers stop and start at the same time and Docker falls behind on removals.
The playbook then fails at "Restart systemd services needing restart at once",
even though the services recover on their own (`Restart=always`) a little later.
The external roles (MASH, devture) were hardened against this in 2026-03
(see mother-of-all-self-hosting/ansible-role-valkey@0ba79c0), but the roles in `roles/custom` never were.
This ports the same bounded cleanup loop to them: stop, force-remove,
and wait until Docker releases the name, failing explicitly after a timeout.

Part of adopting a uniform naming policy for bridge variables,
where the variable prefix matches the role directory name.

Route the whole mautrix-twitter HTTP port via Traefik under
`<matrix-fqn>/bridges/twitter` and populate the existing
appservice.public_address, reusing the matrix_bridges_exposure_*
mechanism. The provisioning shared secret is already auto-generated in
group_vars, so the provisioning API is enabled.

* feat: support container_network=host across all roles + systemd templates
Mirror the pattern Slavi introduced for matrix-coturn (aafa8f0) across the
fork: every 'Ensure X container network is created' task gets a
'when: <var> not in ["", "host"]' guard so MDAD does not try to
docker_network create a network literally named 'host' (returns 403,
since host is a pre-defined Docker network).
Mirror the same guard in every systemd unit template that does
'ExecStartPre=docker network connect <addnet> <container>' loops over
matrix_<role>_container_additional_networks: skip the connects when the
container is on host networking (where additional --network attaches
are invalid).
Unblocks DiD setups where MDAD-managed containers share their host's
network namespace (matrix-mdad outer compose service joined to central
postgres/openldap networks) to reach external services on the outer
Docker daemon.
* Simplify container network guards (!= 'host') and fix duplicate when
Guarding on the empty string ('') as well was misleading: systemd unit
templates still render an unconditional --network= flag, so an empty
network value produces a broken docker create command. Only 'host' is
actually supported, so only guard on that. This also matches the
existing convention in the Traefik role
(when: traefik_container_network != 'host').
Also fix a duplicate when key in the meshtastic-relay role, where the
network-creation task already had a when condition - the two are now
combined into a list.

* Add matrix_bridges_msc4190_enabled flag for using msc4190 on supported mautrix bridges.
* Apply to_json to msc4190 in mautrix configs
* Add | to_json to mautrix bridge registration io.element.msc4190.
* require matrix_synapse_experimental_features_msc3202_device_masquerading_enabled for matrix_bridges_msc4190_enabled
* Also add msc4190 support for mautrix-telegram
Most of these files were defining a service, usually toward the end.
These lines have been moved upward.
Some components (mautrix-signal, mautrix-gmessages, etc.) were defining
a service conditionally (only if metrics are exposed, etc). This was
causing issues like these in the Traefik logs:
> level=error msg="service \"matrix-mautrix-twitter\" error: port is missing" providerName=docker container=matrix-mautrix-twitter-..
This moves the comments from being just in Jinja,
to actually ending up in the generated `labels` file,
which makes inspection of the final result easier.
Also, some new lines were added here and there to make labels
more legible.
The generated file may still include weird new-lines due to
various `if` statements yielding content or not, but that's not so ugly
anymore - now that we have proper start/end sections that are visible in
the final `labels` file.
This is an attempt at optimizing service startup.
The effect is most pronounced when many services are restarted one by one.
The systemd service manager role sometimes does this - for example when `just install-service synapse` runs.
In such cases, a 5-second delay for each Synapse worker service
(or other bridge/bot service that waits on the homeserver) quickly adds up to a lot.
When services are all stopped fully and then started, the effect is not so pronounced, because
`matrix-synapse.service` starts first and pulls all worker services (defined as `Wants=` for it).
Later on, when the systemd service manager role "starts" these worker services, they're started already.
Even if they had a 5-second wait each, it would have happened in parallel.
