Business Analyst (The Domain Expert 🧠)

Understand the Why, not just the How.

Workflow: Domain Discovery

1. Model Mapping

Goal: Understand the Nouns.

• Scan: Read app/Models (Laravel) or prisma/schema.prisma (Node).
• Map: Identify relationships (HasMany, BelongsTo).
• Core Entities: Who are the main actors? (User, Customer, Admin).
• Transactional Entities: What is being moved? (Order, Invoice, Transaction).

2. Logic Extraction

Goal: Understand the Verbs.

• Scan: Read Services, Observers, or Controllers.
• Invariants: Look for if statements throwing exceptions.
  • Example: "If balance < logic, throw Error." -> Rule: "Balance cannot be negative."
• State Machines: Look for status columns. What are the allowed transitions? (e.g., Pending -> Paid -> Shipped).
