Here are 4 comprehensive markdown documentation files for your Logistics OMS system. These files provide complete architectural specifications and can be directly used with Cursor:

### 1. `Order-Creation-System.md`
```markdown
# Order Creation System

## Overview
Excel-like grid interface for creating orders with real-time calculations and supplier integration.

```mermaid
graph TD
    A[Order Grid] --> B[Item Entry]
    B --> C[Price Handling]
    B --> D[Supplier Assignment]
    C --> E[Carrying Charge Calculation]
    D --> F[Payment Type Selection]
    E --> G[Container Pre-plan]
```

## Business Logic

### Price Handling
```javascript
function handlePrice(item) {
  if (item.knownPrice) return item.price;

  // AI-powered estimation
  return (
    historicalData[item.code].avgPrice *
    (1 + marketTrends[item.category])
  );
}
```

### Carrying Charge Calculation
```typescript
const calculateCarryingCharge = (
  basis: 'carton' | 'cbm' | 'weight',
  rate: number,
  item: OrderItem
) => {
  switch(basis) {
    case 'carton': return rate * item.cartons;
    case 'cbm': return rate * (item.unitCbm * item.cartons);
    case 'weight': return rate * (item.unitWeight * item.cartons);
  }
};
```

### Payment Type Handling
```typescript
enum PaymentType {
  CLIENT_DIRECT = 'Client Paid Factory',
  THROUGH_ME = 'Payment Through Me'
}

const paymentFlow = (type: PaymentType) => {
  if (type === PaymentType.CLIENT_DIRECT) {
    system.trackStatus('Factory Payment Pending');
  } else {
    system.initiatePaymentProcess();
  }
};
```

## UI Components
```tsx
<OrderCreationGrid>
  <SmartColumn field="itemCode" editor={CodeAutoComplete} />
  <ImageUploadField />
  <CalculationRow fields={['cbm', 'weight', 'cartons']} />
  <PaymentTypeSelector options={[
    { value: 'direct', label: 'Direct to Factory' },
    { value: 'through_me', label: 'Through Me' }
  ]} />
  <SupplierDropdown matcher={supplierMatchingEngine} />
  <CarryingBasisSelector />
</OrderCreationGrid>
```

## Integration Points
- Supplier API for real-time capacity checks
- Historical price database
- Market rate monitoring service
- Currency exchange API

## Edge Cases
- **Unknown Prices**: Auto-estimate using similar items
- **Mixed Payment Types**: Handle per-item payment flows
- **Unit Conversion**: Automatic kg/lb conversion
- **Bulk Discounts**: Apply tiered pricing automatically
```

### 2. `Warehouse-LoopBack-System.md`
```markdown
# Warehouse Planning & Loop-Back System

## Overview
Automated handling of real-world logistics scenarios including shortages, damages, and quality issues.

```mermaid
sequenceDiagram
    Warehouse->> System: Received Items
    System->> QC: Trigger Inspection
    alt All Items OK
        QC->> System: Approve for Container
    else Partial Shortage
        QC->> System: Report Shortage
        System->> LoopBack: Create New Order
        LoopBack->> Stage1: Add Missing Items
    else Quality Issues
        QC->> System: Flag Defects
        System->> LoopBack: Create Replacement Order
    end
    System->> Container: Update Allocation
```

## Key Algorithms

### Shortage Handling
```typescript
class LoopBackService {
  static handleShortage(originalOrder, item, shortageQty, reason) {
    const newOrder = {
      ...originalOrder,
      items: [{
        ...item,
        quantity: shortageQty,
        loopBackReason: reason
      }],
      parentOrderId: originalOrder.id
    };

    // Apply business rules
    if (reason === 'DAMAGE') {
      newOrder.priority = 'HIGH';
      newOrder.deadline = Date.now() + 7*86400000;
    }

    return newOrder;
  }
}
```

### Container Allocation Logic
```javascript
function optimizeContainerAllocation(items, containers) {
  const allocationPlan = [];
  let remainingItems = [...items];

  containers.forEach(container => {
    const containerLoad = { container, items: [] };
    let remainingCapacity = container.maxCbm;

    // Prioritize complete client orders
    remainingItems = remainingItems.filter(item => {
      const itemCbm = item.unitCbm * item.quantity;

      if (itemCbm <= remainingCapacity) {
        containerLoad.items.push(item);
        remainingCapacity -= itemCbm;
        return false; // remove from remaining
      }
      return true;
    });

    // Handle partial allocations
    remainingItems.forEach(item => {
      const maxQty = Math.floor(remainingCapacity / item.unitCbm);
      if (maxQty > 0) {
        const partialItem = {...item, quantity: maxQty};
        containerLoad.items.push(partialItem);
        remainingCapacity -= maxQty * item.unitCbm;

        // Create shortage record
        LoopBackService.handleShortage(
          item.order,
          item,
          item.quantity - maxQty,
          'PARTIAL_ALLOCATION'
        );
      }
    });

    allocationPlan.push(containerLoad);
  });

  return allocationPlan;
}
```

## UI Components
```tsx
<WarehouseDashboard>
  <QCInspector onResult={(result) => {
    if (result.status === 'FAILED') {
      loopback.createReplacementOrder(result);
    }
  }} />
  <ContainerPlanner3D
    items={receivedItems}
    onAllocationChange={(item, newQty) => {
      if (newQty < item.receivedQty) {
        loopback.handleShortage(item, item.receivedQty - newQty);
      }
    }}
  />
  <LoopBackMonitor />
  <ContainerCapacityGauge />
</WarehouseDashboard>
```

## Integration Points
- Inventory management system
- Quality control databases
- Supplier notification APIs
- Container optimization engine

## Edge Cases
- **Partial Deliveries**: Auto-create loop-back orders
- **Last-Minute Changes**: Real-time container reallocation
- **Multi-Client Items**: Split allocation with priority
- **Capacity Limits**: Warn when exceeding container limits
```

### 3. `Container-Financials.md`
```markdown
# Container Management & Financial System

## Core Architecture
```mermaid
classDiagram
    class Container {
        +string realContainerId
        +string clientFacingId
        +string billNo
        +string sealNo
        +Charge[] charges
        +Milestone[] milestones
        +calculateProfit() number
    }

    class Charge {
        +string name
        +string type
        +number value
        +string currency
    }

    class FinancialEngine {
        +calculateCarryingCharge() number
        +allocateCharges() ChargeAllocation[]
        +calculateProfit() ProfitReport
    }

    Container "1" --> "*" Charge
    FinancialEngine --> Container
```

## Financial Logic

### Charge Allocation
```typescript
const allocateCharges = (container, clients) => {
  const totalCbm = clients.reduce((sum, client) => sum + client.cbmShare, 0);

  return clients.map(client => {
    const allocationRatio = client.cbmShare / totalCbm;
    return {
      clientId: client.id,
      charges: container.charges.map(charge => ({
        ...charge,
        allocatedValue: charge.value * allocationRatio
      }))
    };
  });
};
```

### Profit Calculation
```typescript
class ProfitCalculator {
  static calculate(container) {
    const revenue = container.carryingCharges;

    const costs = container.charges.reduce((total, charge) => {
      const valueINR = charge.currency === 'USD'
        ? charge.value * exchangeRate
        : charge.value;
      return total + valueINR;
    }, 0);

    return {
      grossProfit: revenue - costs,
      margin: ((revenue - costs) / revenue) * 100
    };
  }
}
```

### Container Identification System
```typescript
class ContainerMapper {
  private map = new Map<string, string>();

  createClientFriendlyId(realId: string): string {
    const clientId = `SHIP-${Math.random().toString(36).substr(2, 8).toUpperCase()}`;
    this.map.set(clientId, realId);
    return clientId;
  }
}
```

## UI Components

### Client View
```tsx
<ClientContainerView>
  <ContainerGlassCard>
    <HolographicIdBadge
      id={clientFacingId}
      realId={realContainerId}
      masked={true}
    />
    <TimelineStepper milestones={milestones} />
    <CostBreakdown charges={clientVisibleCharges} />
  </ContainerGlassCard>
</ClientContainerView>
```

### Admin View
```tsx
<AdminContainerView>
  <FinancialDashboard>
    <ProfitGauge value={profitMargin} />
    <CostAllocationTree charges={charges} />
    <ContainerMap realtimeTracking={true} />
  </FinancialDashboard>
</AdminContainerView>
```

## Charge Structure
| Charge Name               | Type       | Value      | Currency |
|---------------------------|------------|------------|----------|
| Duty GST                  | Percentage | 18%        | INR      |
| Clearing Charges          | Fixed      | ₹2,500     | INR      |
| Unloading Charges         | Weight-based | ₹50/kg   | INR      |
| Miscellaneous             | Fixed      | ₹1,200     | INR      |
| Container Marine Insurance| Fixed      | $50        | USD      |
| Container Freight         | Fixed      | $2,950     | USD      |
| Telex Charges             | Fixed      | $75        | USD      |

## Edge Cases
- **Currency Fluctuations**: Lock exchange rates at order creation
- **Shared Costs**: Prorate container charges between clients
- **Partial Shipments**: Adjust carrying charges proportionally
- **Payment Disputes**: Freeze container until resolution
```

### 4. `Security-User-Roles.md`
```markdown
# Security & User Role Management

## Role-Based Access Matrix
| Permission          | Admin | Staff | Client |
|---------------------|-------|-------|--------|
| View all orders     | ✓     | ✓     | ✗      |
| Edit financials     | ✓     | ✗     | ✗      |
| View profits        | ✓     | ✗     | ✗      |
| Create users        | ✓     | ✗     | ✗      |
| Edit own orders     | ✓     | ✓     | ✗      |
| View container IDs  | ✓     | ✓     | Masked |
| Initiate loop-backs | ✓     | ✓     | ✗      |
| View all clients    | ✓     | ✓     | ✗      |

## Data Isolation Architecture
```mermaid
sequenceDiagram
    User->>API: Request /orders
    API->>Auth: Verify token
    Auth->>API: Return user roles
    alt Client User
        API->>Database: SELECT * FROM orders WHERE client_id = {user.clientId}
    else Staff User
        API->>Database: SELECT * FROM orders
        API->>Data: Mask financial fields
    else Admin
        API->>Database: SELECT * FROM orders
    end
    API->>User: Return filtered data
```

## Implementation Code

### Authentication Middleware
```typescript
app.use('/api', (req, res, next) => {
  const token = req.headers.authorization;
  const user = authService.verifyToken(token);

  if (!user) return res.status(401).send();

  // Attach user to request
  req.user = user;
  next();
});
```

### Data Filtering
```typescript
// Row-Level Security Middleware
app.use('/api/orders', (req, res, next) => {
  if (req.user.role === 'client') {
    req.query.clientId = req.user.clientId;
  }
  next();
});

// Field Masking Transformer
const maskFinancials = (data, user) => {
  if (user.role !== 'admin') {
    return data.map(item => ({
      ...item,
      unitCost: undefined,
      profitMargin: undefined,
      supplierPrice: undefined
    }));
  }
  return data;
};
```

### Container ID Masking
```typescript
class ContainerService {
  getContainer(id, user) {
    const container = db.getContainer(id);

    if (user.role === 'client') {
      return {
        ...container,
        realContainerId: undefined,
        clientFacingId: containerMapper.getClientFacingId(container.realContainerId)
      };
    }
    return container;
  }
}
```

## Audit Trail System
```typescript
class AuditLogger {
  static log(action: string, user: User, details: object) {
    db.create('audit_logs', {
      timestamp: new Date(),
      action,
      userId: user.id,
      ip: request.ip,
      userAgent: request.headers['user-agent'],
      details: JSON.stringify(details)
    });
  }
}

// Usage
AuditLogger.log(
  'LOOPBACK_CREATED',
  currentUser,
  { originalOrder: 'ORD-1001', newOrder: 'LOOP-2837' }
);
```
