This reference describes the full structure of `surfaceCompositionQueryBinding`. 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

| `[kind=collection].destinationKey` | `string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u` | **Required.** Stable key reference to the corresponding named declaration; the compiler checks existence and compatibility. |
| `[kind=collection].viewKey` | `string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u` | **Required.** Stable key reference to the corresponding named declaration; the compiler checks existence and compatibility. |
| `[kind=home-section].kind` | `"home-section"` | **Required.** Selects the variant and the properties admitted in this branch. |
| `[kind=home-section].sectionKey` | `string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u` | **Required.** Stable key reference to the corresponding named declaration; the compiler checks existence and compatibility. |
| `[kind=home-section].viewKey` | `string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u` | **Required.** Stable key reference to the corresponding named declaration; the compiler checks existence and compatibility. |
| `[kind=record-section].kind` | `"record-section"` | **Required.** Selects the variant and the properties admitted in this branch. |
| `[kind=record-section].recordProfileKey` | `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. |

## 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
{
  "kind": "home-section",
  "sectionKey": "continue-work",
  "viewKey": "workshop-view"
}
```
