## Production models

Real models from production business applications, anonymized and published as they are. Their labels are in Spanish because the applications serve Spanish-speaking users. They show what large, long-lived models look like, including older conventions (for example `menu=` attributes instead of `@`); for new models, follow the [specification](../docs/language-spec.md).

- [Expenses.txt](production/Expenses.txt) — Expense reports with approval workflow, master/detail, dynamic values (150 lines)
- [CRM.txt](production/CRM.txt) — Lead management CRM: tabs by state, complex filters, batch actions (379 lines)
- [HR.txt](production/HR.txt) — Human resources: employees, offices, per-user subsets, many listings (549 lines)
- [Tickets.txt](production/Tickets.txt) — Help desk tickets: role-based listings, state machine, notifications (546 lines)
