| 3 | This is the routing entry point for business-logic and state-machine issues. |

| 5 | ## When to Use |
| 6 | |
| 7 | - The target involves coupons, inventory, payment, approvals, quotas, invites, trials, or state transitions |
| 8 | - The issue is not parser-level; it is about when checks happen and which business conditions are checked |
| 9 | - You suspect race conditions, workflow bypass, price tampering, negative values, stacked discounts, or multi-step flaws |

| 15 | ## Recommended Flow |
| 16 | |
| 17 | 1. First map key business states and one-time actions |
| 18 | 2. Then check for check-then-act windows, sequence dependencies, or missing cross-step authorization |
| 19 | 3. If the chain depends on APIs, uploads, or object permissions, return to the corresponding router skill to complete the path |
