-- 1. Enumerations first (no dependencies)
create enumeration CRM.OrderStatus (
  Pending 'Pending',
  Approved 'Approved',
  Rejected 'Rejected',
  Completed 'Completed'
);

-- 2. Entities (may reference enumerations)
create persistent entity CRM.Customer (...);
create persistent entity CRM.Order (...);

-- 3. Associations (reference entities)
create association CRM.Order_Customer from CRM.Order to CRM.Customer type reference;

-- Core CRUD microflows
create microflow CRM.ACT_Customer_Save ($Customer: CRM.Customer)
begin
  -- Validation (from SmartForms rules)
  if $Customer/Email = empty then
    validation feedback $Customer/Email message 'Email is required';
    return false;
  end if;

  commit $Customer;
  return true;
end;

-- Workflow logic
create microflow CRM.ACT_Order_Submit ($Order: CRM.Order)
begin
  -- Workflow start logic
  ...
end;

-- Overview pages
create page CRM.Customer_Overview (...);

-- Edit pages (can reference microflows from Phase 2)
create page CRM.Customer_Edit (...);

mdl 1;
-- Module roles matching K2 roles
create module role CRM.Manager description 'Can approve orders and manage customers';
create module role CRM.User description 'Can create and edit own records';

-- Access rules
grant create, delete, read *, write * on entity CRM.Order to CRM.Manager;
grant create, read *, write * on entity CRM.Order to CRM.User where [System.owner = '[%CurrentUser%]'];

event-based UI logic → nanoflows
validation → validation microflows + validation feedback
data manipulation → microflows
Complex calculations → microflow expressions
