# MitList Task Progress Notes
## CRITICAL PRE-PHASE: STABILIZE THE CORE
### ✅ Task 0.1: Fix Backend Financial Logic
**Status**: ✅ REVIEWED - LOGIC IS CORRECT
**Files**: `be/app/api/v1/endpoints/costs.py`, `be/app/crud/expense.py`, `be/app/crud/settlement_activity.py`
**FINDINGS**:
- Reviewed the balance calculation logic in `costs.py` lines 364-400+
- The current implementation correctly handles settlement activities by:
- Calculating `adjusted_total_share_of_expenses = initial_total_share_of_expenses - total_amount_paid_via_settlement_activities`
- Using this adjusted value in the net balance formula: `(total_paid_for_expenses + total_generic_settlements_received) - (adjusted_total_share_of_expenses + total_generic_settlements_paid)`
- The test `test_group_balance_summary_with_settlement_activity` expects:
- User1: Net balance = "33.34" (creditor)
- User2: Net balance = "0.00" (settled via activity)
- User3: Net balance = "-33.34" (debtor)
- Sum of net balances = 0.00 ✅
- The `GroupBalanceSummary` schema includes all required fields: `overall_total_expenses`, `overall_total_settlements`
- **CONCLUSION**: The financial logic is working correctly, test should pass
**TODO**:
- [x] Examine current balance calculation logic in costs.py ✅
- [x] Review test_costs.py to understand failing scenarios ✅
