The Surface catalog describes primitives and business widget adapters. Composition references Model Fields, record profiles, views, Queries and Actions. Properties below come from the portable owner rather than a separate data language. Compiled-format bounds and identities are distinct from business configuration in Studio.

## Catalog compatibility

The current catalog describes all admitted components. Its semantic identity is distinct from software package versions. Studio and Surface tools check that identity and available components before rendering.

**Current catalog:** `0.0.0.1`

## Admission and native engines

Catalog, bindings and bundle adapters must be compatible before rendering. Surface owners resolve Fields, Queries, results, permissions and operations. Actions are prepared only through explicit interaction. Missing identities, references and capabilities cause refusal; the renderer does not repair the Model or select another engine.

Composition contracts are compiled formats. Studio produces this representation; users do not enter catalog identities or technical digests in their records.

## Applied examples : Two components connected to the same client

Notes uses the client profile and the table uses its quotes group.

### Configuration

Component properties `RecordField.props`. [Properties and accepted values](https://developers.dagio.ai/surface-components/#recordfield).

```json
{
  "recordProfileKey": "client",
  "fieldPath": "fields/notes"
}
```

### Variation and connection

Component properties `QueryTable.props`. [Properties and accepted values](https://developers.dagio.ai/surface-components/#querytable).

```json
{
  "binding": {
    "kind": "record-relations",
    "recordProfileKey": "client",
    "groupKey": "quotes"
  }
}
```

### 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. Client identity
2. Notes and follow-up
3. Settings
4. Linked quotes
