Business Logic Router

This is the routing entry point for business-logic and state-machine issues.

When to Use

• The target involves coupons, inventory, payment, approvals, quotas, invites, trials, or state transitions
• The issue is not parser-level; it is about when checks happen and which business conditions are checked
• You suspect race conditions, workflow bypass, price tampering, negative values, stacked discounts, or multi-step flaws

Skill Map

• Business Logic Vulnerabilities

1. First map key business states and one-time actions
2. Then check for check-then-act windows, sequence dependencies, or missing cross-step authorization
3. If the chain depends on APIs, uploads, or object permissions, return to the corresponding router skill to complete the path
