+cat <<'EOF'
+Recommended sequence (after clearing any stuck deployer txs on 138 — see CHAIN138_XDC_ZERO_DEPLOYMENT_TROUBLESHOOTING.md):
+
+1. RPC:     bash scripts/verify/xdc-zero-chain138-preflight.sh
+2. Config:  bash scripts/validation/validate-xdc-zero-config.sh
+3. Relayer: bash scripts/xdc-zero/clone-and-build-xdc-relayer.sh
+            # Configure Redis + copy config/xdc-zero/xdc-relayer.dotenv.example to the relayer clone .env
+            # or copy config/xdc-zero/xdc-zero-relayer-138-pair.example.defaults to /etc/default/xdc-zero-relayer-138-pair
+            # Policy: relayer/service SUBNET_URL should use https://rpc-http-pub.d-bis.org, not Core
+4. Deploy parent Endpoint + CSC (XDC-Zero endpoint/, network xdcparentnet) — manual or upstream scripts; use stock CSC for production.
+5. Deploy 138 Endpoint:
+            XDC_ZERO_REPO=~/projects/XDC-Zero bash scripts/xdc-zero/deploy-endpoint-chain138.sh
+            # If Hardhat stalls on Besu, rerun with:
+            # XDC_ZERO_REPO=~/projects/XDC-Zero bash scripts/xdc-zero/deploy-endpoint-chain138.sh --manual
+   Optional spike CSC on 138:
+            bash scripts/xdc-zero/cast-deploy-simplecsc-chain138.sh
+6. Addresses → fragments:
+            export ENDPOINT_ON_138=... CSC_PARENT_ON_138=... ENDPOINT_ON_PARENT=... CSC_138_ON_PARENT=...
+            bash scripts/xdc-zero/set-fragment-addresses.sh
+7. Merge:   XDC_ZERO_CHAIN138_FRAG=.../deployed/endpointconfig.fragment.chain138.json \
+            XDC_ZERO_REG_FRAG=.../deployed/xdcparentnet-register-chain138.fragment.json \
+            bash scripts/xdc-zero/merge-endpointconfig-chain138.sh /path/to/XDC-Zero/endpoint/endpointconfig.json
+8. Register chains:
+            XDC_ZERO_ENDPOINT_DIR=.../XDC-Zero/endpoint bash scripts/xdc-zero/run-registerchain-both.sh
+9. Apps + approve:
+            XDC_ZERO_ENDPOINT_DIR=... bash scripts/xdc-zero/run-registerapplications-both.sh
+10. systemd: install config/systemd/xdc-zero-relayer-138-pair.example.service
+            # Use config/xdc-zero/xdc-zero-relayer-138-pair.example.defaults for /etc/default/xdc-zero-relayer-138-pair
