The Pi now runs registry.mc02.dev/schulcloud-mcp. Its compose file `!reset`s
the build section docker-compose.yml declares, so no `docker compose` command
there can fall back to building (Compose 2.24 or later). SCHULCLOUD_MCP_TAG
pins a commit's image; unset, the Pi follows `latest`.
`npm run publish-image` publishes from a development machine. It builds only a
clean working tree, so a commit tag names exactly that commit's code, for amd64
and arm64, tagged `latest` and with the short commit id. On an x86 machine
arm64 builds under QEMU, which the script checks for and explains rather than
registering unasked.
PI.md logs in to the registry, pulls and starts instead of building, and
updates by publishing and pulling. Rehearsed in a scratch compose project: the
image came from the registry, `up -d --build` built nothing, and the server
came up healthy with its database and no published ports.

docs/PI.md goes from a Pi with Docker to a working claude.ai connector:
configuration, the first token, Caddy, DNS, the VPS forwarding raw TCP,
checks from outside, connecting the clients, the monthly token, updates,
backups and troubleshooting.
docker-compose.override.yml is tracked, so Compose would have merged it on
the Pi as well — publishing ports and switching the crawl timer off. The
Pi's .env sets COMPOSE_FILE to add deploy/docker-compose.pi.yml instead,
which joins the existing Caddy network by name and builds DATABASE_URL, so
nothing tracked needs editing there. Postgres moves to a private network
shared only with the server.
