# PRE-04 primitive-domain reproduction

This deterministic JavaScript fixture demonstrates the distinction between
changing a string's shape and constructing a canonical domain value.

It:

- shows that uppercase-only handling accepts unknown, three-letter, and name
  inputs;
- accepts mixed-case and canonical two-letter codes through a synthetic
  catalogue;
- rejects unsupported representations; and
- proves equality through canonical identity.

Run:

```sh
node experiment.mjs
```

The five-code catalogue is synthetic. The fixture is not private application
code, a complete country standard, an incident replay, or evidence that every
primitive needs a wrapper.
