-- Shape B (`/opt/plato-deploy/{webhook.py,deploy.sh}`, port `9799`).
-- The in-LXC checkout's `origin` is `http://192.168.8.121:3000/dtoro/Plato.git` (internal gitea), and git creds are at `/root/.git-credentials` rather than the `/etc/plato-deploy/git-credentials` pattern — the unit doesn't set `ProtectHome` so root's home is reachable.
-- `/data` is a host bind (`/mnt/library/documents/plato`), so `docker compose up -d --build` rebuilds the image + restarts the container without touching the SQLite db. The [fresh-DB bootstrap workaround](../containers/126-plato.md#fresh-db-bootstrap-workaround) only matters if you blow `plato.db` away.

Configured `origin` on the in-LXC checkout is the internal URL.

 ## Changelog
 
+### 2026-06-28 — Plato pipeline decommissioned
+LXC 126 destroyed, webhook id 8 on `dtoro/Plato` removed. `192.168.8.190` removed from gitea `app.ini` `ALLOWED_HOST_LIST`.
+
 ### 2026-06-24 — terminalito pipeline added
 Webhook id 12 on `dtoro/terminalito` → `http://192.168.8.211:9797/deploy` on [trmnl (128)](../containers/128-trmnl.md). Shape B (`server/deploy/webhook.py` receiver, in-repo `server/deploy/deploy.sh`; secret `/etc/terminalito-deploy/secret`). `app.ini` `ALLOWED_HOST_LIST` extended with `192.168.8.211`. Verified end-to-end with a push. Repo-local `credential.helper` in `/opt/terminalito/.git/config` (the unit can't read root's global git config).
