# Verification Scripts

Scripts for ingress, NPMplus, DNS, and source-of-truth verification.

## Dependencies

Required tools (install before running):

| Tool | Purpose | Install |
|------|---------|---------|
| `bash` | Shell (4.0+) | Default on most systems |
| `curl` | API calls, HTTP | `apt install curl` |
| `jq` | JSON parsing | `apt install jq` |
| `dig` | DNS resolution | `apt install dnsutils` |
| `openssl` | SSL certificate inspection | `apt install openssl` |
| `ssh` | Remote execution | `apt install openssh-client` |
| `ss` | Port checking | `apt install iproute2` |
| `systemctl` | Service status | System (systemd) |
| `sqlite3` | Database backup | `apt install sqlite3` |

Optional (recommended for automation): `sshpass`, `rsync`, `screen`, `tmux`, `htop`, `shellcheck`, `parallel`. See [docs/11-references/APT_PACKAGES_CHECKLIST.md](../../docs/11-references/APT_PACKAGES_CHECKLIST.md) § Automation / jump host.  
One-line install (Debian/Ubuntu): `sudo apt install -y sshpass rsync dnsutils iproute2 screen tmux htop shellcheck parallel`

| Tool | Purpose |
|------|---------|
| `wscat` or `websocat` | WebSocket testing (manual verification) |

## Scripts

- `backup-npmplus.sh` - Full NPMplus backup (database, API exports, certificates)
- `check-contracts-on-chain-138.sh` - Check that Chain 138 deployed contracts have bytecode on-chain (`cast code` for 31 addresses; requires `cast` and RPC access). Use `[RPC_URL]` or env `RPC_URL_138`; `--dry-run` lists addresses only (no RPC calls); `SKIP_EXIT=1` to exit 0 when RPC unreachable.
- `reconcile-env-canonical.sh` - Emit recommended .env lines for Chain 138 (canonical source of truth); use to reconcile `smom-dbis-138/.env` with [CONTRACT_ADDRESSES_REFERENCE](../../docs/11-references/CONTRACT_ADDRESSES_REFERENCE.md). Usage: `./scripts/verify/reconcile-env-canonical.sh [--print]`
- `check-deployer-balance-blockscout-vs-rpc.sh` - Compare deployer native balance from Blockscout API vs RPC (to verify index matches current chain); see [EXPLORER_AND_BLOCKSCAN_REFERENCE](../../docs/11-references/EXPLORER_AND_BLOCKSCAN_REFERENCE.md)
- `check-dependencies.sh` - Verify required tools (bash, curl, jq, openssl, ssh)
- `export-cloudflare-dns-records.sh` - Export Cloudflare DNS records
- `export-npmplus-config.sh` - Export NPMplus proxy hosts and certificates via API
- `generate-source-of-truth.sh` - Combine verification outputs into canonical JSON
- `run-full-verification.sh` - Run full verification suite
- `verify-backend-vms.sh` - Verify backend VMs (status, IPs, nginx configs)
- `verify-end-to-end-routing.sh` - E2E routing verification
- `verify-udm-pro-port-forwarding.sh` - UDM Pro port forwarding checks
- `verify-websocket.sh` - WebSocket connectivity test (requires websocat or wscat)

## Task runners (no LAN vs from LAN)

- **From anywhere (no LAN/creds):** `../run-completable-tasks-from-anywhere.sh` — runs config validation, on-chain contract check, run-all-validation --skip-genesis, and reconcile-env-canonical.
- **From LAN (NPM_PASSWORD, optional PRIVATE_KEY):** `../run-operator-tasks-from-lan.sh` — runs W0-1 (NPMplus RPC fix), W0-3 (NPMplus backup), O-1 (Blockscout verification); use `--dry-run` to print commands only. See [ALL_TASKS_DETAILED_STEPS](../../docs/00-meta/ALL_TASKS_DETAILED_STEPS.md).

## Environment

Set variables in `.env` or export before running. See project root `.env.example` and [docs/04-configuration/VERIFICATION_GAPS_AND_TODOS.md](../../docs/04-configuration/VERIFICATION_GAPS_AND_TODOS.md).
