# Data Model: Inline Confirmation Buttons

## Entities

### ConfirmButton State

The `ConfirmButton` manages a single piece of ephemeral UI state:

| Field | Type | Description |
|-------|------|-------------|
| isConfirming | boolean | Whether the button is in the "confirm" (armed) state |

**State transitions**:

```
idle ──[first click/Enter/Space]──▶ confirming
confirming ──[second click/Enter/Space]──▶ action executed → idle (or unmount)
confirming ──[5s timeout]──▶ idle
confirming ──[Escape]──▶ idle
confirming ──[click outside]──▶ idle
confirming ──[focus loss]──▶ idle
```

### ConfirmButton Props (Component Interface)

| Prop | Type | Required | Description |
|------|------|----------|-------------|
| onConfirm | () => void | yes | Callback executed on confirmed second activation |
| icon | ReactElement | yes | The default icon to display (e.g., X, Trash2) |
| label | string | yes | Accessible label for the button (used in aria-label and title) |
| className | string | no | Additional CSS classes passed through to the underlying button |
| disabled | boolean | no | When true, the button cannot enter confirm state |

**Notes**:
- No domain entities are created or modified by this feature.
- The confirm state is purely ephemeral — never persisted, never serialized.
- The component does not introduce any new domain types or application-layer changes.
