+## deploy-all.sh dry-run
+
+Validate keeper deploy wiring without broadcasting transactions or mutating `.env`.
+
+```bash
+cd smom-dbis-138
+DRY_RUN=1 bash scripts/reserve/deploy-all.sh
+# or
+bash scripts/reserve/deploy-all.sh --dry-run
+```
+
+Dry-run behavior:
+
+- Prints each deployment step and the `PRICE_FEED_KEEPER_ADDRESS` read from `.env` (must match `0xD3AD6831aacB5386B8A25BB8D8176a6C8a026f04` for Chain 138).
+- Skips `forge script` `--broadcast` / `--verify` and does not append addresses to `.env`.
+- When `DEPLOY_CHAINLINK=true` or `DEPLOY_GELATO=true`, prints the optional Chainlink/Gelato forge commands and follow-up setup scripts that would run.
+
+Live deploy (no `DRY_RUN`): same script without dry-run flags; requires `PRIVATE_KEY` and uses `RPC_URL_138` (default `https://rpc.d-bis.org`).
