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

> Promote moves one Startup’s refinement into a Template, so every Startup that extends the Template inherits it.

Promote moves one [Startup](/business/nouns/startup)’s refinement into a [Template](/business/nouns/template), so every Startup that extends the Template inherits it.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `template` | [Template](/business/nouns/template) | Yes | The Template that receives the refinement. |
| `startup` | [Startup](/business/nouns/startup) | Yes | The Startup that holds the refinement. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `change` | [Change](/business/nouns/change) | Yes | The Change against the Template. |
| `template` | [Template](/business/nouns/template) | Yes | The Template that received the refinement. |

## Effects
- Emits [`Template.promoted`](/business/events/Template.promoted).
- Opens a Change against the Template.
- Reaches each extending Startup as an `upgrade`.

## 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. | [Template.promote](/business/nouns/template/promote) |
| 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. | [Template.promote](/business/nouns/template/promote) |

## 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`. |
