### Remaining Work

#### Horizontal Slices (Deferred)
- **F023**: Migrate 81 UI components to @alga-psa/ui-kit (large task)
- **F027**: Migrate auth strategies (tightly coupled to NextAuth)
- **F029**: Migrate permission utilities (tightly coupled to User model and database)
- **F030**: Migrate getCurrentUser function (placeholder - depends on NextAuth)

#### Vertical Slices (Remaining Component Migrations)
- F058-F063: @alga-psa/scheduling component/action/model migrations (structure done in F057)
- F065-F068: @alga-psa/workflows component/action migrations (structure done in F064)
- F070-F073: @alga-psa/documents component/handler/action migrations (structure done in F069)
- F075-F077: @alga-psa/assets component/action migrations (structure done in F074)
- F079-F081: @alga-psa/surveys component/action migrations (structure done in F078)
- F083-F087: @alga-psa/integrations component/email/webhook migrations (structure done in F082)
- F089-F091: @alga-psa/client-portal component migrations (structure done in F088)

#### Technical Features (F092-F104)
- TypeScript path aliases
- CE/EE separation pattern
- NX computation caching
- NX remote caching for CI
- nx affected commands
- Module boundary enforcement

#### Backwards Compatibility (F105-F110)
- Re-exports from shared package
- Consumer updates

### Tests Added

#### @alga-psa/billing tests
- **Location:** packages/billing/tests/
- **Contents:**
  - invoice.test.ts - Tests for Invoice model validation logic (tenant required, integer validation for amounts)
  - contract.test.ts - Tests for Contract model validation logic (tenant required for all operations)

#### @alga-psa/scheduling tests
- **Location:** packages/scheduling/tests/
- **Contents:**
  - scheduleEntry.test.ts - Tests for ScheduleEntry model validation logic (tenant required, recurrence pattern parsing)

### Known Issues
1. TypeScript errors about @alga-psa/core, @alga-psa/types not found - expected until `npm install` links workspaces
2. Event publisher has temporary workflow dependencies from @alga-psa/shared
3. 81 UI components remain in server/src/components/ui (needs incremental migration)
4. getCurrentTenantId is tightly coupled to Next.js (headers, session) - vertical slice models use explicit tenant parameter
5. Server actions ('use server') cannot be migrated to packages - they stay in server/src but can call into package business logic

## Summary Statistics
- **Total Features:** 110
- **Implemented:** 38 (34.5%)
- **Phase 1 Complete:** Yes (foundation modules established)
- **Phase 2 Complete:** All 11 vertical slice module structures created
- **Phase 3-4:** Model migrations in progress (clients, tickets, projects, billing, scheduling models done)
