The SDK wraps the orchestrator REST API and the on-chain proof-registry reads
behind one class.

## new Solva(config) [#new-solvaconfig]

```ts
new Solva({
  network: "testnet" | "mainnet" | "local",
  tenant: string,
  endpoints?: Partial<NetworkConfig>,
  apiKey?: string,
});
```

`network` selects the default endpoints. `endpoints` overrides any of them, for
example to point at a local stack.

## Methods [#methods]

| Method                  | Returns                    | Description                                       |
| ----------------------- | -------------------------- | ------------------------------------------------- |
| `connectSource(config)` | `Promise<string>`          | Register a reserve source, returns the source id. |
| `runProofCycle()`       | `Promise<string>`          | Trigger a cycle, returns the published proof id.  |
| `getLatestProof()`      | `Promise<Proof>`           | Fetch the latest published proof.                 |
| `getProof(id)`          | `Promise<Proof>`           | Fetch a proof by id.                              |
| `verifyInclusion(ref)`  | `Promise<InclusionResult>` | Verify a customer's inclusion on-chain.           |

## Errors [#errors]

Every failure is a typed error: `OrchestratorError` for REST failures (carries
the HTTP `status`), `ChainError` for on-chain read failures, and `ConfigError`
for invalid configuration. All extend `SolvaError`.
