# review

URL: /business/nouns/change/review · Id: `verb:Change.review` · Call: `await $.Change.review({ … })` (SDK) or the `do` tool at `https://api.sb/mcp`. Inputs says what to pass, Outputs what returns, When it waits who approves.

> Review runs every Evaluator on a Change’s preview and records each verdict on the Change.

Review runs every [Evaluator](/business/nouns/evaluator) on a [Change](/business/nouns/change)’s preview and records each verdict on the Change.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `change` | [Change](/business/nouns/change) | Yes | The open Change. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `change` | [Change](/business/nouns/change) | Yes | The Change with its verdicts. |

## Effects
- Emits [`Change.reviewed`](/business/events/Change.reviewed).
- Performed by the [Quality Lead](/agents/quality/quality-lead).
- Opens an Approval when the Change’s stakes exceed the Startup’s threshold.
- Moves each Issue the Change resolves to in progress.
- Waits for each Integration-bound Evaluator’s outside run on the head and records its result as a verdict.

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | [Change.review](/business/nouns/change/review) |
| The record is not in a state that allows this Verb, so the call is refused. | [`refused`](/code/api/errors/refused) | Read the record, run the Verb that moves it to an allowed state, then retry. | [Change.review](/business/nouns/change/review) |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Low: two-way, nothing at stake |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | None: it runs once review passes. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
