## Complete Example

A realistic `.tdn` file demonstrating all major features:

          "dat_content": [

            ["resolution", "1920x1080"],

    {
      "name": "renderer",
      "type": "baseCOMP",
      "position": [500, 0],
      "size": [300, 150],
      "custom_pars": {
        "About": {
          "$t": "about",
          "Build": 1,
          "Version": "0.9.0"
        }
      }
    }
  ]
}
```

## Key Observations

### Type Defaults
Both `baseCOMP`s share `resizecomp` and `repocomp` expressions, so those are hoisted into `type_defaults` instead of being repeated on each operator.

### Parameter Templates
The "About" page definition (Build + Version parameters) is shared between `controller` and `renderer`, so the structure is defined once in `par_templates` and each operator references it with `$t` and provides its own values.

### Expression Shorthand
`"=parent().par.Speed / 10"` — expressions are prefixed with `=` instead of wrapped in an object like `{"expr": "..."}`.

### Flags as Arrays
`["viewer"]`, `["display"]`, `["lock"]` — compact array format instead of `{"viewer": true}`.

### Simplified Connections
`["noise1"]` — just the source operator name. Array position equals input index.

### Optional Position
`noise1` at `[0, 0]` omits `position` entirely. Only operators not at the origin include their position.

### Compact Formatting
Short arrays like `[300, 0]`, `[0.2, 0.4, 0.8]`, `["core"]` are inlined on a single line.

## Minimal Example

The simplest possible `.tdn` file — a single operator with no custom settings:

```json
{
  "format": "tdn",
  "version": "1.0",
  "generator": "Embody/5.0.140",
  "td_build": "2025.32280",
  "exported_at": "2026-03-01T12:00:00Z",
  "network_path": "/project1",
  "options": {
    "include_dat_content": false
  },
  "operators": [
    {
      "name": "noise1",
      "type": "noiseTOP"
    }
  ]
}
```

## Annotation Example

A network with annotations grouping related operators:

```json
{
  "format": "tdn",
  "version": "1.0",
  "generator": "Embody/5.0.140",
  "td_build": "2025.32280",
  "exported_at": "2026-03-01T12:00:00Z",
  "network_path": "/project1/main",
  "options": {
    "include_dat_content": true
  },
  "operators": [
    {
      "name": "noise1",
      "type": "noiseTOP"
    },
    {
      "name": "level1",
      "type": "levelTOP",
      "position": [300, 0],
      "inputs": ["noise1"]
    },
    {
      "name": "config",
      "type": "tableDAT",
      "position": [0, -400],
      "dat_content": [
        ["key", "value"],
        ["fps", "60"]
      ],
      "dat_content_format": "table"
    }
  ],
  "annotations": [
    {
      "name": "annot_visuals",
      "mode": "annotate",
      "title": "Visual Processing",
      "text": "Noise generation and level adjustment",
      "position": [-70, -170],
      "size": [670, 440]
    },
    {
      "name": "annot_config",
      "mode": "annotate",
      "title": "Configuration",
      "text": "Project settings",
      "position": [-70, -570],
      "size": [370, 340]
    }
  ]
}
```
