# Complete Flow Segregation - Implementation Summary

## Overview

This document describes the **complete segregation** of request flows into dedicated folders. Each flow type (CUSTOM, DEALER_CLAIM) now has ALL its related components, hooks, services, utilities, and types in its own folder. Only truly shared components remain in the `shared/` folder.

## What Was Done

### 1. Created Complete Folder Structure

#### Custom Flow (`src/flows/custom/`)
```
custom/
├── components/
│   ├── request-detail/
│   │   ├── OverviewTab.tsx          # Custom request overview
│   │   └── WorkflowTab.tsx          # Custom request workflow
│   └── request-creation/
│       └── CreateRequest.tsx        # Custom request creation
└── index.ts                         # Exports all custom components
```

#### Dealer Claim Flow (`src/flows/dealer-claim/`)
```
dealer-claim/
├── components/
│   ├── request-detail/
│   │   ├── OverviewTab.tsx          # Dealer claim overview
│   │   ├── WorkflowTab.tsx          # Dealer claim workflow
│   │   ├── IOTab.tsx                # IO management (dealer claim specific)
│   │   ├── claim-cards/             # All dealer claim cards
│   │   │   ├── ActivityInformationCard.tsx
│   │   │   ├── DealerInformationCard.tsx
│   │   │   ├── ProcessDetailsCard.tsx
│   │   │   ├── ProposalDetailsCard.tsx
│   │   │   └── RequestInitiatorCard.tsx
│   │   └── modals/                  # All dealer claim modals
│   │       ├── CreditNoteSAPModal.tsx
│   │       ├── DealerCompletionDocumentsModal.tsx
│   │       ├── DealerProposalSubmissionModal.tsx
│   │       ├── DeptLeadIOApprovalModal.tsx
│   │       ├── EditClaimAmountModal.tsx
│   │       ├── EmailNotificationTemplateModal.tsx
│   │       └── InitiatorProposalApprovalModal.tsx
│   └── request-creation/
│       └── ClaimManagementWizard.tsx # Dealer claim creation
└── index.ts                         # Exports all dealer claim components
```

#### Shared Components (`src/flows/shared/`)
```
shared/
└── components/
    └── request-detail/
        ├── DocumentsTab.tsx         # Used by all flows
        ├── ActivityTab.tsx          # Used by all flows
        ├── WorkNotesTab.tsx         # Used by all flows
        ├── SummaryTab.tsx           # Used by all flows
        ├── RequestDetailHeader.tsx  # Used by all flows
        ├── QuickActionsSidebar.tsx  # Used by all flows
        └── RequestDetailModals.tsx  # Used by all flows
```

### 2. Updated Flow Registry

The flow registry (`src/flows/index.ts`) now:
- Exports all flow modules
- Provides utility functions to get flow-specific components
- Includes `getCreateRequestComponent()` for request creation
- Exports `SharedComponents` for shared components

### 3. Updated RequestDetail Component

The `RequestDetail` component now:
- Uses flow registry to get flow-specific components
- Imports shared components from `SharedComponents`
- Dynamically loads appropriate tabs based on flow type
- Maintains backward compatibility

## File Organization Rules

### ✅ Flow-Specific Files → Flow Folders

**Custom Flow:**
- Custom request creation wizard
- Custom request detail tabs (Overview, Workflow)
- Custom request hooks (future)
- Custom request services (future)
- Custom request utilities (future)
- Custom request types (future)

**Dealer Claim Flow:**
- Dealer claim creation wizard
- Dealer claim detail tabs (Overview, Workflow, IO)
- Dealer claim cards (Activity, Dealer, Process, Proposal, Initiator)
- Dealer claim modals (all 7 modals)
- Dealer claim hooks (future)
- Dealer claim services (future)
- Dealer claim utilities (future)
- Dealer claim types (future)

### ✅ Shared Files → Shared Folder

**Shared Components:**
- DocumentsTab (used by all flows)
- ActivityTab (used by all flows)
- WorkNotesTab (used by all flows)
- SummaryTab (used by all flows)
- RequestDetailHeader (used by all flows)
- QuickActionsSidebar (used by all flows)
- RequestDetailModals (used by all flows)

## Usage Examples

### Getting Flow-Specific Components

```typescript
import { getOverviewTab, getWorkflowTab, getCreateRequestComponent } from '@/flows';
import { getRequestFlowType } from '@/utils/requestTypeUtils';

const flowType = getRequestFlowType(request);
const OverviewTab = getOverviewTab(flowType);
const WorkflowTab = getWorkflowTab(flowType);
const CreateRequest = getCreateRequestComponent(flowType);
```

### Using Shared Components

```typescript
import { SharedComponents } from '@/flows';

const { DocumentsTab, ActivityTab, WorkNotesTab, SummaryTab } = SharedComponents;
```

### Direct Access to Flow Components

```typescript
import { CustomFlow, DealerClaimFlow } from '@/flows';

// Custom flow
<CustomFlow.CustomOverviewTab {...props} />
<CustomFlow.CustomCreateRequest {...props} />

// Dealer claim flow
<DealerClaimFlow.DealerClaimOverviewTab {...props} />
<DealerClaimFlow.IOTab {...props} />
<DealerClaimFlow.ClaimManagementWizard {...props} />
```

## Benefits

1. **Complete Segregation**: Each flow is completely isolated
2. **Easy Navigation**: All files for a flow type are in one place
3. **Maintainability**: Changes to one flow don't affect others
4. **Scalability**: Easy to add new flow types
5. **Clarity**: Clear separation between flow-specific and shared code
6. **Type Safety**: TypeScript ensures correct usage

## Next Steps (Future Enhancements)

1. **Move Flow-Specific Hooks**
   - Custom hooks → `flows/custom/hooks/`
   - Dealer claim hooks → `flows/dealer-claim/hooks/`

2. **Move Flow-Specific Services**
   - Custom services → `flows/custom/services/`
   - Dealer claim services → `flows/dealer-claim/services/`

3. **Move Flow-Specific Utilities**
   - Custom utilities → `flows/custom/utils/`
   - Dealer claim utilities → `flows/dealer-claim/utils/`

4. **Move Flow-Specific Types**
   - Custom types → `flows/custom/types/`
   - Dealer claim types → `flows/dealer-claim/types/`

### Registry
- `src/flows/index.ts` (updated with new structure)

## Files Modified

- `src/pages/RequestDetail/RequestDetail.tsx` - Uses new flow structure
- `src/flows/README.md` - Updated with complete segregation documentation

## Conclusion

The complete segregation is now in place. Each flow type has its own dedicated folder with all related components. This makes it easy to:
- Find all files related to a specific flow type
- Maintain and update flow-specific code
- Add new flow types without affecting existing ones
- Understand what is shared vs. flow-specific

The architecture is now truly modular and plug-and-play!
