## Workflow

Defines a complete workflow with nodes, edges, inputs, and outputs.

### Fields

## Edge

Connects a source node to destination(s) with conditional routing.

### Fields

| Field     | Type        | Required | Description |
| --------- | ----------- | -------- | ----------- |
| `from`    | string      | Yes      | -           |
| `cases`   | EdgeCase\[] | No       | -           |
| `default` | string\[]   | No       | -           |

## EdgeCase

Defines one conditional routing path from an edge.

### Fields

| Field       | Type      | Required | Description |
| ----------- | --------- | -------- | ----------- |
| `to`        | string\[] | No       | -           |
| `condition` | string    | No       | -           |
| `label`     | string    | No       | -           |

## Syntax Sugar (YAML-only)

These fields are not part of the proto schema — they are YAML convenience features that desugar to standard nodes, edges, and entry at parse time.

### `sequence:`

Top-level workflow field. Replaces `entry:` + `nodes:` + sequential `edges:` for linear chains. Cannot coexist with `entry:`.

### `type: parallel` (node type)

A node with `type: parallel` and `branches:` expands into branch nodes + a join node + fan-out/fan-in edges. The parallel node's `id` becomes the join node's id.

See workflow documentation for full examples and usage patterns.
