Function verifyExport

verifyExport(
    lines: Iterable<string>,
    publicKeysHex: readonly string[],
    digest?: Digest,
): Promise<VerifyReport>
Runs the full offline verification: re-prove every account's chain from the file's links, then check the embedded checkpoint's root and signature against the supplied public keys. The checkpoint verifies against the exported tip, so a checkpoint sealed before the last postings reports as unverified until the ledger is exported right after a seal.
Parameters
- lines: Iterable<string>
- publicKeysHex: readonly string[]
- digest: Digest = ...
Returns Promise<VerifyReport>
Example
```
import { readFileSync } from 'node:fs';
const lines = readFileSync('ledger-export.jsonl', 'utf8').split('\n');
const report = await verifyExport(lines, [publishedSigningKeyHex]);
if (!report.chainIntact) throw new Error('export chain broken');
```
