> Deploy points a Startup’s live address at a Version, so every Interface serves that build.

Deploy points a [Startup](/business/nouns/startup)’s live address at a [Version](/business/nouns/version), so every [Interface](/business/nouns/interface) serves that build.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `version` | [Version](/business/nouns/version) | Yes | The Version to serve. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `version` | [Version](/business/nouns/version) | Yes | The Version, now live. |

## Effects
- Emits [`Version.deployed`](/business/events/Version.deployed).
- Performed by the [Engineering Lead](/agents/engineering/engineering-lead).
- Keeps the previous Version, so a `revert` restores it.
- At a share of 100, resolves every Issue whose last open Change this Version carries.
- Refuses `live` when a Secret a Function declares is missing in `live`.

## 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. | [Version.deploy](/business/nouns/version/deploy) |
| 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. | [Version.deploy](/business/nouns/version/deploy) |
| `live` when a Secret a Function declares is missing in `live` | [`refused`](/code/api/errors/refused) | Clear what the check names, then call it again. | [Version.deploy](/business/nouns/version/deploy) |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Medium: two-way, visible |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | 1 business hour, in which a watcher can pause, redirect or cancel it; then it runs. |
| 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`. |
