# SurfaceTriggerDeadline · types

   
                                       
                                                                                 
                                                
                  
           
          
   

The following types define named objects and their relationships. Tables include inherited properties. Schema-derived types refer to their validated structures; a TypeScript declaration does not replace the compiler’s semantic checks.

## SurfaceTriggerDeadline

Technical scheduling policy never grants access or executes the proposed Action.

```typescript
export type SurfaceTriggerDeadline = z.infer<typeof surfaceTriggerDeadlineSchema>;
```

## Applied examples : Propose a review at the right time

A change to the amount proposes a review; a deadline bounds the watched objects.

### Configuration

Fragment placed in `triggers[]`. [Properties and accepted values](https://developers.dagio.ai/reference/workspace-model-foundation/).

```json
{
  "key": "quote-review",
  "enabledByDefault": false,
  "event": {
    "kind": "revision",
    "definitionPaths": [
      "workspace/quotes/surface/quote"
    ],
    "fieldKeys": [
      "amount"
    ]
  },
  "ruleKeys": [
    "positive-amount"
  ],
  "actionKey": "review-quote",
  "mode": "propose",
  "executionCapability": null,
  "maximumCascadeDepth": 1,
  "historicalEvents": "explicit-backfill-only"
}
```

### Variation and connection

Fragment placed in `triggers[].deadline`. [Properties and accepted values](https://developers.dagio.ai/reference/surface-trigger-deadline/).

```json
{
  "contract": "SurfaceTriggerDeadline@2",
  "sourceQueryKey": "pending-quotes",
  "maximumScheduledNodes": 50,
  "lateToleranceMs": 300000
}
```

### UI layout example

The illustrative layout below places this configuration in the Clients/Quotes app. Insert each fragment at the stated location, with Field, Query and Action references matching the Model declarations.

1. Qualify need
2. Prepare proposal
3. Wait for decision
4. Retain result
