# surfaceTriggerDeadline

   
                               
                                                                                 
                                          
                  
           
          
   

This reference describes the full structure of `surfaceTriggerDeadline`. Paths include nested objects, list items and conditional branches. A branch selected by `kind`, `contract` or `mode` only admits its own properties.

## Structure and values

| Field | Options / expected values | Description |
| --- | --- | --- |
| `contract` | `"SurfaceTriggerDeadline@2"` | **Required.** Exact discriminant of this contract variant. Match the literal value shown. |
| `sourceQueryKey` | `string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u` | **Required.** Stable key reference to the corresponding named declaration; the compiler checks existence and compatibility. |
| `maximumScheduledNodes` | `integer; ≥ 1; ≤ 10000` | **Required.** Cardinality or budget bound for the named resource. Exceeding the bound is refused; null denotes no bound only where admitted by the schema. |
| `lateToleranceMs` | `integer; ≥ 0; ≤ 86400000` | **Required.** Defines late Tolerance Ms for this object. Observe the type, variants and bounds in the Options column. |
| `localTime` | `string; /^(?:[01]\d\|2[0-3]):[0-5]\d:[0-5]\d$/u; optional` | Optional. Local time in the required format, interpreted in the declared timezone. |

## Reading the contract

A path ending in `[]` describes each list item; `{key}` describes each dictionary value. The `↻` marker refers to the same recursive expression. Closed objects reject additional properties. Semantic validation denotes an additional check: matching a type does not make a reference, permission or transition valid. References must resolve in the Model and the current user context.

An older variant cannot accept properties belonging to a newer variant. The compiler checks the version and consistency of the complete Model.

## Structural example

This fragment passes the schema for this section. Its business references must be defined in the enclosing Model.

```json
{
  "contract": "SurfaceTriggerDeadline@2",
  "sourceQueryKey": "releases",
  "maximumScheduledNodes": 100,
  "lateToleranceMs": 0,
  "localTime": "09:00:00"
}
```
