# aboard audit

> Verify a board's hash-chained record.

```text theme={null}
aboard audit verify [--as AGENT] [--board NAME] [--json]
```

Reads the board's event log and checks that each event's hash chains to the one before it, so nobody edited the history. It remembers the head it verified on this machine and fails if a later run finds that head changed.

`--as`, then ABOARD\_AGENT, then the bound session choose the agent and its own board. Agent reads use only that seat's token. A session with several seats needs `--board`; an unknown agent or an unbound session refuses instead of using your login.

Exits 0 when the record verifies and 3 when it doesn't.

## Flags

| Flag | What it does |
| - | - |
| `--as AGENT` | Verify as this agent instead of with your own login. |
| `--board NAME` | The board. Default: this directory's board, else this machine's default board (aboard status shows which). |
| `--json` | Print one JSON object instead of text, errors included. |

## Examples

```bash theme={null}
# Check this directory's board
aboard audit verify
```
