survos/shape-contracts
======================

[](#survosshape-contracts)

Shared PHP value objects for physical shape and dimensions.

This package is deliberately framework-free. It defines the stable payload that importers, DTO contracts, folio browsing, Symfony bundles, Doctrine storage, parsers, and UI renderers can agree on.

Scope
-----

[](#scope)

`shape-contracts` owns:

- unit identifiers and conversion to millimeters
- immutable single-axis lengths
- immutable physical shape values with nullable axes
- normalized array round-tripping for JSON/DTO payloads

It does not own Symfony services, Doctrine mapping, Twig filters, form types, icons, or free-text parsing. Those belong in `survos/shape-bundle` or `survos/dimensions-bundle`.

Example
-------

[](#example)

```
use Survos\ShapeContracts\Length;
use Survos\ShapeContracts\Shape;
use Survos\ShapeContracts\Unit;

$shape = new Shape(
    width: Length::from(18, Unit::CM),
    height: Length::from(22, Unit::CM),
    source: '18 x 22 cm',
);

$shape->toNormalizedArray();
// [
//   'widthMm' => 180,
//   'heightMm' => 220,
//   'depthMm' => null,
//   'lengthMm' => null,
//   'thicknessMm' => null,
//   'diameterMm' => null,
//   'label' => null,
//   'source' => '18 x 22 cm',
// ]
```

Normalized JSON shape
---------------------

[](#normalized-json-shape)

Use camel-case millimeter keys so JSON can be copied directly into DTO data:

```
{
  "widthMm": 180,
  "heightMm": 220,
  "depthMm": null,
  "lengthMm": null,
  "thicknessMm": null,
  "diameterMm": null,
  "label": null,
  "source": "18 x 22 cm"
}
```

The original source/display string should remain in the museum `dimensions` field when available. The structured shape is a companion field for consistent storage, querying, and rendering.
