This reference describes the full structure of `managedNumericFieldV2`. 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` | `"ManagedNumericField@2"` | **Required.** Exact discriminant of this contract variant. Match the literal value shown. |
| `key` | `string; min length 1; max length 120; /^[a-zA-Z][a-zA-Z0-9]*$/u` | **Required.** Stable semantic identifier used by references; changing it changes identity. |
| `type` | `"decimal"` | **Required.** Defines type for this object. Observe the type, variants and bounds in the Options column. |
| `required` | `true \| false` | **Required.** Whether a value is required by this declaration. |
| `repeatable` | `true \| false` | **Required.** Whether multiple values or instances are admitted. |
| `precision` | `integer; ≥ 1; ≤ 1000` | **Required.** Defines precision for this object. Observe the type, variants and bounds in the Options column. |
| `scale` | `integer; ≥ 0; ≤ 1000` | **Required.** Defines scale for this object. Observe the type, variants and bounds in the Options column. |
| `unit` | `closed object OR closed object OR closed object` | **Required.** Defines unit for this object. Observe the type, variants and bounds in the Options column. |
| `unit.[kind=dimensionless].kind` | `"dimensionless"` | **Required.** Selects the variant and the properties admitted in this branch. |
| `unit.[kind=unit].kind` | `"unit"` | **Required.** Selects the variant and the properties admitted in this branch. |
| `unit.[kind=unit].key` | `string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u` | **Required.** Stable semantic identifier used by references; changing it changes identity. |
| `unit.[kind=currency].kind` | `"currency"` | **Required.** Selects the variant and the properties admitted in this branch. |
| `unit.[kind=currency].key` | `string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u` | **Required.** Stable semantic identifier used by references; changing it changes identity. |
| `default` | `string; max length 1003 OR Array<string; max length 1003>; max length 1000; optional` | Optional. Initial value matching the declared type; does not replace an existing saved value. |
| `minimum` | `string; max length 1003; optional` | Optional. Cardinality or budget bound for the named resource. Exceeding the bound is refused; null denotes no bound only where admitted by the schema. |
| `maximum` | `string; max length 1003; optional` | Optional. Cardinality or budget bound for the named resource. Exceeding the bound is refused; null denotes no bound only where admitted by the schema. |

## 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": "ManagedNumericField@2",
  "key": "estimatedEffortHours",
  "type": "decimal",
  "required": false,
  "repeatable": false,
  "precision": 10,
  "scale": 2,
  "unit": {
    "kind": "unit",
    "key": "hour"
  },
  "minimum": "0.00",
  "maximum": "1000000.00"
}
```
