# CHG-10 durable-identity reproduction
This deterministic fixture demonstrates the mechanism in “Deprecation Is a
Migration, Not a Warning.”
It verifies that:
- PHP deserializes an object with an unavailable class identity as
`__PHP_Incomplete_Class`; and
- versioned JSON intent can be handled through a current registry without
loading that legacy class.
Run:
```sh
php -d zend.assertions=1 -d assert.exception=1 experiment.php
```
The fixture does not execute a queue framework or reproduce a private payload,
deployment, failure, or migration. All identities and values are synthetic.
