The Configuration Options table lists defaultDisk with default “—”, but the implementation falls back to "local" when defaultDisk is not provided (see DiskManager). Please update the Default column and/or description to reflect the actual fallback behavior so the docs don’t imply there is no default.

Suggested change

	| `defaultDisk` | `string` | — | Default disk name used when `disk` is omitted |
	| `defaultDisk` | `string` | `'local'` | Default disk name used when `disk` is omitted |
