+# Non-Critical Type Errors - Fix Progress
+
+## Status: In Progress
+
+Fixing non-critical TypeScript type errors systematically.
+
+## ✅ Completed Fixes
+
+### 1. AccountType Enum Issues
+- **Files Fixed**:
+  - `src/integration/plugins/temenos-adapter.ts`
+  - `src/integration/plugins/flexcube-adapter.ts`
+  - `src/integration/plugins/iso20022-adapter.ts`
+  - `src/integration/plugins/swift-adapter.ts`
+- **Fix**: Imported `AccountType` enum and used enum values instead of string literals
+
+### 2. JsonValue Type Issues (Partial)
+- **Files Fixed**:
+  - `src/core/accounting/reporting-engine.service.ts` - Added `Prisma.InputJsonValue` casting
+  - `src/core/admin/dbis-admin/controls/corridor-controls.service.ts` - Added `Prisma.InputJsonValue` casting
+
+## ⚠️ Remaining Issues
+
+Given the large number of errors (hundreds), the remaining errors fall into these categories:
+
+1. **JsonValue Type Mismatches** (~100+ instances)
+   - Need to cast `Record<string, unknown>` to `Prisma.InputJsonValue`
+   - Pattern: `as Prisma.InputJsonValue`
+
+2. **Property Access Errors** (~50+ instances)
+   - Missing properties in Prisma query results
+   - Often due to incorrect `include` statements or schema mismatches
+
+3. **Missing Return Statements** (~100+ instances)
+   - Route handlers missing explicit returns in all code paths
+   - Pattern: Add `return` statements or throw errors
+
+4. **Decimal Method Errors** (~30+ instances)
+   - Using `isGreaterThan`, `isLessThan` instead of `greaterThan`, `lessThan`
+   - Pattern: Replace method names
+
+5. **Unknown Type Errors** (~20+ instances)
+   - Objects typed as `unknown` need type assertions
+   - Pattern: Add proper type assertions
+
+## Strategy
+
+Due to the volume of errors, I'm focusing on:
+1. **High-impact fixes**: Fixing the most common patterns first
+2. **Systematic approach**: Creating patterns that can be applied broadly
+3. **Priority files**: Core services and commonly used code paths
+
+## Next Steps
+
+Continue fixing errors systematically, focusing on:
+1. JsonValue issues in core services
+2. Property access errors that are easy to fix
+3. Missing return statements in route handlers
