@@ -13,13 +13,17 @@ THOUGHT PROCESS:
- The service uses async/await throughout for FastAPI compatibility.
- 2-Level MLM: distribute_commission() resolves Gen1 (direct referrer) and
Gen2 (upline) payouts using commission_percent and upline_commission_percent.
- Phase 3: Conflict Detection — before creating/updating a rule, the service
checks for overlapping active rules with the same tier/region/is_campaign
combination. If a conflict exists and force_override is False, a 409 is
returned. If force_override is True, the conflicting rule is deactivated.

- Fully decoupled from payment gateway implementation (Strategy Pattern).
- Commission distribution is separated so the caller can run it as a

- Uses the existing PaymentRouter for PaymentIntent creation and the
