This reference describes the full structure of `managedExactDataValueType`. 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 |
| --- | --- | --- |
| `format` | `closed object; semantic validation` | **Required.** Presentation format compatible with the value type. |
| `format.precision` | `integer; ≥ 1; ≤ 1000` | **Required.** Defines precision for this object. Observe the type, variants and bounds in the Options column. |
| `format.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. |

## 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
{
  "format": {
    "precision": 1,
    "scale": 0
  },
  "unit": {
    "kind": "dimensionless"
  }
}
```
