# POS Loyalty Member Customization

This custom Odoo module enhances the POS Loyalty interface and partner creation wizard, optimizing workflow efficiency and resolving critical multi-company operational constraints.

## Features

1. **Strict Customer Selection Filter:**
   - Limits customer loading and search lists in the POS UI strictly to real individuals who hold an active membership or loyalty card (`is_loyalty_member = True`).
   - Automatically excludes cashier accounts, user accounts, and company partners from being selected as customers.

2. **Simplified Customer Creation Wizard:**
   - Overrides the POS Customer Edit/Creation screen to show only essential details:
     * Name
     * Phone
     * Email
     * Address (Street, Zip, City, State, Country)
     * Birthday

3. **Automatic Lowest Level Membership Assignment:**
   - Automatically provisions new partners with a loyalty card for the lowest membership tier (`Membership Silver`) immediately upon registration.

4. **Robust Multi-Company Loyalty Processing:**
   - Solves a core Odoo 19 multi-company operational bug where cashiers in branch companies encounter "Access Errors" when validating orders for customers whose loyalty cards belong to the parent company.
   - Bypasses company-specific record rules during POS loyalty audit logging using standard and safe `sudo` environment execution.

5. **Loyalty Reward and Point Access Control:**
   - Restricts loyalty program reward eligibility, point balance displays, and program applicability in the POS UI strictly to customers who have a persisted, active card in the database for that specific program.
   - Prevents unauthorized claim/access to zero-point rewards (e.g., 100% discount rewards in executive/exclusive programs) by non-enrolled members.

## Technical Details
- **JS OWL Patching:** Overrides POS frontend partner management and order processing (`PosOrder`) safely using clean, standard owl-level class overrides to filter program eligibility, claimable rewards, and loyalty point lists based on card status.
- **Python Inheritance:** Customizes backend models (`res.partner`, `pos.order`) to clean loading domains and securely provision cross-company data.
