## Usage

All playbooks are designed to be run via `ansible-playbook` with `extra_vars`:

No `versions.yml` required — all variables can be passed via `extra_vars`.

## Interactive Deployment Flow

When deploying a new validator, the agent should guide the user through variable collection
in this order. See `AGENT.md` for the full step-by-step flow and `examples/inventory.yml`
for the generated output format.

### Required Variables (must collect)

| Variable | Prompt | Validation |
|---|---|---|
| `server_ip` | "Target server IP?" | Valid IPv4 |
| `network` | "Mainnet or testnet?" | `mainnet` or `testnet` |
| `region` | "Server region? (amsterdam, frankfurt, tokyo, ny, ...)" | String |
| `validator_type` | "Which validator type?" | `jito`, `jito-bam`, `agave`, `firedancer-agave`, `firedancer-jito` |
| `solana_version` | "Solana version? (default: 3.1.8)" | Semver |
| `jito_version` | "Jito version?" (if jito/jito-bam) | Semver |
| `firedancer_version` | "Firedancer version?" (if firedancer) | String |
| `identity_account` | "Validator identity pubkey? (or generate)" | Base58 pubkey or `generate` |
| `vote_account` | "Vote account pubkey? (or generate)" | Base58 pubkey or `generate` |
| `snapshot_url` | "Snapshot URL? (auto-detected for ERPC nodes)" | URL (cannot be empty for init) |

### Optional Variables (show defaults, confirm)

| Variable | Default | When Required |
|---|---|---|
| `ssh_user` | `solv` (`ubuntu` for fresh servers) | Always |
| `commission_bps` | `0` | Always |
| `dynamic_port_range` | `8000-8025` | Always |
| `limit_ledger_size` | `200000000` | Always |
| `allowed_ssh_ips` | — | Strongly recommended (UFW) |
| `allowed_ips` | — | Optional (UFW) |
| `block_engine_url` | Auto by region | Jito types only |
| `shred_receiver_address` | Auto by region | Jito types only |
| `expected_shred_version` | Epoch-dependent | Testnet only |
| `expected_bank_hash` | Epoch-dependent | Testnet (optional) |
| `wait_for_supermajority` | Epoch-dependent | Testnet (optional) |

### Optional: Reference RPC

| Variable | Description | Default |
|---|---|---|
| `reference_rpc_url` | Reference RPC endpoint for slot sync comparison (e.g., ERPC) | — |

ERPC API keys are free at https://erpc.global — enables full slot sync monitoring during deployment and updates.

### Pre-flight: Fresh Server Setup

If the target is a new server without a `solv` user:

### Deployment Command

All paths relative to skill's `ansible/` directory:

### Dry-Run First

Always offer `--check` mode before actual deployment:
