+# Bug Fixes - December 9, 2025
+
+## Bug 1: Unreachable Return Statement in `costOptimization` Resolver
+
+### Issue
+The `costOptimization` resolver in `api/src/schema/resolvers.ts` had an unreachable return statement at line 407. Lines 397-406 already returned the mapped recommendations, making line 407 dead code that would never execute.
+
+### Root Cause
+Incomplete refactoring where both the mapped return value and the original return statement were left in place.
+
+### Fix
+Removed the unreachable `return billingService.getCostOptimization(args.tenantId)` statement at line 407.
+
+### Files Changed
+- `api/src/schema/resolvers.ts` (line 407)
+
+---
+
+## Bug 2: N+1 Query Problem in `getResources` Function
+
+### Issue
+The `getResources` function in `api/src/services/resource.ts` executed one query to fetch resources, then called `mapResource` for each row. The `mapResource` function executed an additional database query to fetch site information for every resource (line 293). This created an N+1 query problem: if you fetched 100 resources, you executed 101 queries instead of 1-2 optimized queries.
+
+### Impact
+- **Performance**: Severely degraded performance with large datasets
+- **Database Load**: Unnecessary database load and connection overhead
+- **Scalability**: Does not scale well as the number of resources grows
+
+### Root Cause
+The original implementation fetched resources first, then made individual queries for each resource's site information.
+
+### Fix
+1. **Modified `getResources` function** to use a `LEFT JOIN` query that fetches both resources and sites in a single database query
+2. **Created `mapResourceWithSite` function** to map the joined query results without making additional database queries
+3. **Preserved `mapResource` function** for single resource lookups (used by `getResource` and other functions)
+
+### Performance Improvement
+- **Before**: N+1 queries (1 for resources + N for sites)
+- **After**: 1 query (resources and sites joined)
+- **Example**: Fetching 100 resources now uses 1 query instead of 101 queries
+
+### Files Changed
+- `api/src/services/resource.ts`:
+  - Modified `getResources` function (lines 47-92)
+  - Added `mapResourceWithSite` function (lines 303-365)
+  - Preserved `mapResource` function for backward compatibility
+
+---
+
+## Testing Recommendations
+
+1. **Bug 1**: Verify that `costOptimization` resolver returns the correct recommendations without errors
+2. **Bug 2**:
+   - Test `getResources` with various filter combinations
+   - Verify that site information is correctly populated
+   - Monitor database query count to confirm N+1 problem is resolved
+   - Test with large datasets (100+ resources) to verify performance improvement
+
+---
+
+## Verification
+
+Both bugs have been verified:
+- ✅ Bug 1: Unreachable code removed
+- ✅ Bug 2: N+1 query problem fixed with JOIN query
+- ✅ No linter errors introduced
+- ✅ Backward compatibility maintained (single resource lookups still work)
