README

Framework-agnostic loyalty point and tier management engine for the Nexus ERP ecosystem.

Overview

The Nexus\Loyalty package provides a highly granular, atomic loyalty engine designed to manage member point balances, tier qualifications, and redemption constraints. It is built as a Layer 1 package, meaning it contains pure business logic with no framework dependencies.

Core Principles

1. Framework-Agnostic: Pure PHP 8.3 with no dependencies on Laravel or Symfony.
2. Stateless Design: All persistence is handled via externalized repository interfaces.
3. Strict Immutability: All Value Objects and core services follow strict immutability patterns.
4. Multi-Tenancy Ready: Designed to work within the Nexus multi-tenant ecosystem.

Features

• Point Accrual Engine: Precise point calculation with rounding strategies and multi-factor multipliers.
• Tier Management: Flexible tier qualification using rolling activity windows and retention logic.
• Redemption & Validation: Rule-based redemption with minimum thresholds and FIFO expiry prioritization.
• Point Integrity: Audit-ready adjustment logging and idempotency support.
• Coalition Support: Multi-brand point sharing and brand-specific balance tracking.

Architecture

• Layer 1 (Atomic Package): Contains pure domain logic, entities, and value objects.
• Namespace: Nexus\Loyalty
• Purity: No use Illuminate\* or framework-specific imports allowed.
