+- **Host**: orangevps
+- **Service**: systemd unit `teleuploader` (env via `/etc/teleuploader/env` / BWS secrets)
+- **Build**: Nix flake (`flake.nix`) — `nix build .#teleuploader` → `nix copy` → `systemctl restart teleuploader`
+- **CI**: `.github/workflows/deploy.yml` (Gitea Actions / GitHub Actions)
+- **Port**: `4000` (`PORT` env)
+- **Domain**: `https://upload.asepharyana.my.id`
+- **Reverse proxy**: Caddy (bukan Traefik/Docker)
+- **Database**: `postgresql://asephs:***@100.121.180.82:6432/uploader` (PgBouncer pool di imrnes, **bukan** 5432/localhost)
+- `deploy.sh` & `Dockerfile` & `docker-compose.yml` bersifat **legacy** — jangan dipakai untuk deploy produksi.

-URL backend tetap permanen: `https://tele.asepharyana.my.id/f/{public_id}`
+URL backend tetap permanen: `https://upload.asepharyana.my.id/f/{public_id}`
 Ini berarti URL service Anda fix, bukan jaminan file Telegram abadi.
