TypeScript Type Errors - Fixed ✅

Summary

Fixed all critical TypeScript type errors related to IdentityType and UI component compilation.

Fixes Applied

1. IdentityType Enum Usage ✅

• File: dbis_core/src/sovereign/omnl/omnl.service.ts
• Issue: String literals ('Treasury', 'CBDC', 'Settlement', 'API') used instead of enum values
• Fix:
  • Added import: import { IdentityType } from '@/shared/types';
  • Replaced string literals with enum values: IdentityType.TREASURY, IdentityType.CBDC, IdentityType.SETTLEMENT, IdentityType.API

2. Type Mapping in getSovereignIdentities ✅

• File: dbis_core/src/sovereign/identity/sovereign-identity-fabric.service.ts
• Issue: Database returns identityType as string but interface expects IdentityType enum
• Fix: Added mapping to cast identityType to enum type

3. Null vs Undefined Type Mismatch ✅

• File: dbis_core/src/sovereign/identity/sovereign-identity-fabric.service.ts
• Issue: Database fields are string | null but interface expects string | undefined
• Fix: Convert null to undefined using nullish coalescing operator: ?? undefined

4. Unused Imports/Variables ✅

• Files:
  • dbis_core/src/sovereign/omnl/omnl.service.ts - Removed unused uuidv4 import
  • dbis_core/src/sovereign/identity/sovereign-identity-fabric.service.ts - Removed unused HSMService import
  • dbis_core/src/sovereign/instances/multitenancy.service.ts - Prefixed unused parameters with _

5. UI Components Exclusion ✅

• File: dbis_core/tsconfig.json
• Issue: UI components (which use window object) were being compiled for Node.js API build
• Fix: Added src/ui/**/* and src/__tests__/**/* to exclude array in tsconfig.json

Current Status

• ✅ IdentityType enum errors: FIXED
• ✅ UI component compilation errors: FIXED (excluded from build)
• ✅ Type mapping errors: FIXED
• ⚠️ Remaining errors: Type-checking warnings and non-critical type mismatches in integration plugins and admin dashboards (these are mostly unused variables and property access issues that don't block runtime)
