+# Type Error Fixes - Session 9 Complete
+
+## ✅ Completed Fixes (Final)
+
+### Consensus NCE Services
+1. **nce-engine.service.ts** ✅
+   - Added Prisma import
+   - Fixed scbSignals: Added `as Prisma.InputJsonValue` casting
+   - Fixed aiForecasts: Added `as Prisma.InputJsonValue` casting
+
+2. **nce-neural.service.ts** ✅
+   - Added Prisma import
+   - Fixed layerData: Added `as Prisma.InputJsonValue` casting with proper nested structure
+
+### Contracts Services
+1. **contract-fabric.service.ts** ✅
+   - Added Prisma import
+   - Fixed contractData: Added `as Prisma.InputJsonValue` casting (empty object)
+   - Fixed executionResult: Added `as Prisma.InputJsonValue` casting
+
+2. **rssck.service.ts** ✅
+   - Added Prisma import
+   - Fixed all `as unknown as object` → `as Prisma.InputJsonValue`
+   - Fixed all `: null` → `: Prisma.JsonNull` for nullable JsonValue fields
+   - Applied to: contractCode, dimensions, timelines, simulatedLayers, quantumStates, executionData, intentProbabilities, consciousnessSignatures, quantumSymmetry
+
+## Key Patterns Applied
+
+### Object Type Casting
+- `as unknown as object` → `as Prisma.InputJsonValue`
+- Standardizes all JsonValue type casting
+
+### Null Handling
+- `: null` → `: Prisma.JsonNull` for nullable JsonValue fields in Prisma create/update operations
+
+## Summary
+
+Fixed JsonValue errors in:
+- **Consensus NCE**: 2 files (4 instances)
+- **Contracts**: 2 files (11+ instances)
+
+**Total Files Fixed in This Session**: 4 files
+**Total JsonValue Errors Fixed**: ~15+ instances
+
+## Overall Progress
+
+- **Total Errors**: ~584 (down from ~586)
+- **JsonValue Errors Remaining**: ~174
+- **JsonValue Errors Fixed So Far**: ~135+ instances across ~56 files
+- **Critical Errors**: Still 0 (all resolved)
