+# Orphan Containers — Canonical Configuration
+
+Two containers on this VM run without an on-disk compose file:
+
+| Container | Image | Memory Limit | Restart Policy | Source |
+|---|---|---|---|---|
+| `trading-backend` | `bytelyst-trading-bot-service-trading-backend` | **768 MiB** | always | compose file deleted; image present |
+| `gitea-npm-registry` | `gitea/gitea:1.22` | **512 MiB** | unless-stopped | started via `docker run` |
+
+Both have runtime memory limits applied via `docker update`. Limits persist across
+restarts of the same container but are lost on `docker rm`. If recreated, use the
+recovery procedures below.
+
+---
+
+## trading-backend
+
+Compose file referenced by container labels:
+`/opt/bytelyst/trading/bytelyst-trading-bot-service/docker-compose.yml` — **missing on disk**.
+
+Only the `logs/` directory remains; the bind mount references it.
+
+### Recovery procedure
+If the container is removed, recreate the compose file with:
+
+```yaml
+services:
+  trading-backend:
+    image: bytelyst-trading-bot-service-trading-backend
+    container_name: trading-backend
+    user: node
+    working_dir: /app
+    entrypoint: ["docker-entrypoint.sh"]
+    command: ["node", "dist/index.js"]
+    env_file:
+      - .env                # holds secrets — restore from backup
+    environment:
+      ENABLE_TRADING: "true"
+      PAPER_TRADING: "true"
+      EXECUTION_PROVIDER: alpaca
+      ALPACA_SUBTAG_ENV: paper
+      SYMBOLS: "BTC/USDT,ETH/USDT,SOL/USDT,DOGE/USDT,PEPE/USDT"
+      TOTAL_CAPITAL: "1000"
+      EXECUTION_TIMEFRAME: 15m
+      POLLING_INTERVAL: "60000"
+    volumes:
+      - /opt/bytelyst/trading/bytelyst-trading-bot-service/logs:/app/logs
+    networks:
+      - default
+    restart: always
+    deploy:
+      resources:
+        limits:
+          memory: 768m
+
+networks:
+  default:
+    name: learning_ai_common_plat_default
+    external: true
+```
+
+Full env captured via `docker inspect` is needed for secrets; check `.env` backup
+or recover from hermes drive backup.
+
+---
+
+## gitea-npm-registry
+
+Started via raw `docker run` rather than compose. The internal package registry
+service used by ByteLyst monorepos for `@bytelyst/*` package distribution.
+
+### Recovery procedure
+
+```bash
+docker run -d \
+  --name gitea-npm-registry \
+  --restart unless-stopped \
+  --memory 512m --memory-swap 512m \
+  -p 3300:3000 \
+  -v gitea-data:/data \
+  -e GITEA__server__DOMAIN=gitea.bytelyst.com \
+  -e GITEA__server__SSH_DOMAIN=gitea.bytelyst.com \
+  -e GITEA__server__ROOT_URL=https://gitea.bytelyst.com/ \
+  -e GITEA__server__HTTP_PORT=3000 \
+  -e GITEA__packages__ENABLED=true \
+  -e GITEA__security__INSTALL_LOCK=true \
+  -e INSTALL_LOCK=true \
+  --network bridge \
+  gitea/gitea:1.22
+
+docker network connect learning_ai_common_plat_default gitea-npm-registry
+```
+
+The `gitea-data` named volume contains all repository + package state; never
+delete it without a backup.
