# CLQMS MVP Todo List

> Clinical Laboratory Quality Management System - Minimum Viable Product

## Quick Start: Create Order with Minimal Master Data

You **don't need** all master data finished to create an order. Here's what's actually required:

### Minimum Required (2 Tables)

These are the only tables that need database entries for a minimal setup. System lookups (status, priority, etc.) are handled by the `ValueSet` library using static JSON files in `app/Libraries/Data/`.

```sql
-- 1. Patient (already exists in codebase)
-- Just need at least 1 patient

-- 2. Counter for Order ID
INSERT INTO counter (CounterName, CounterValue) VALUES ('ORDER', 1);
```

### API Endpoints (No Auth Required for Testing)

```bash
# Create demo order (auto-creates patient if needed)
POST /api/demo/order
{
  "PatientID": "PT001",
  "NameFirst": "John",
  "NameLast": "Doe",
  "Gender": "1",
  "Birthdate": "1990-05-15",
  "Priority": "R",
  "OrderingProvider": "Dr. Smith"
}

# List orders
GET /api/demo/orders

# Create order (requires auth)
POST /api/ordertest
{
  "InternalPID": 1,
  "Priority": "R",
  "OrderingProvider": "Dr. Smith"
}

# Update order status
POST /api/ordertest/status
{
  "OrderID": "00250112000001",
  "OrderStatus": "SCH"
}
```

## Core Workflow
Order → Collection → Reception → Preparation → Analysis → Verification → Review → Reporting

---

## Phase 4: Master Data (Already Have - Need Completion)

### 4.1 Test Definitions ✅ Existing

## Quick Test: Does Order Creation Work?

```bash
# Test 1: Create demo order (no auth required)
curl -X POST http://localhost:8080/api/demo/order \
  -H "Content-Type: application/json" \
  -d '{"NameFirst": "Test", "NameLast": "Patient"}'

# Expected Response:
{
  "status": "success",
  "message": "Demo order created successfully",
  "data": {
    "PatientID": "DEMO1736689600",
    "InternalPID": 1,
    "OrderID": "00250112000001",
    "OrderStatus": "ORD"
  }
}

# Test 2: Update order status
curl -X POST http://localhost:8080/api/ordertest/status \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <token>" \
  -d '{"OrderID": "00250112000001", "OrderStatus": "SCH"}'
```

## Success Criteria

### Functional
- [x] Patient registration works
- [ ] Test ordering generates valid OrderID and SID
- [ ] Specimens track through collection → transport → reception → preparation → analysis
- [ ] Results can be entered with reference range validation
- [ ] Results verified through VER → REV → REP workflow
- [ ] Instruments can send results via Edge API

### Non-Functional
- [ ] JWT authentication required for all endpoints
- [ ] Soft delete (DelDate) on all transactions
- [ ] UTC timezone for all datetime fields
- [ ] Audit logging for data changes
- [ ] < 2s response time for standard queries

---

## Current Codebase Status

### Controllers (Need Work)
- [ ] OrderTestController - placeholder code, incomplete
- [ ] ResultController - only validates JWT
- [x] PatientController - complete
- [x] TestsController - complete
- [x] PatVisitController - partial

### Models (Good)
- [x] PatientModel - complete
- [x] TestDef* models - complete
- [x] Ref* models - complete
- [x] ValueSet* models - complete
- [x] SpecimenModel - exists, needs API

### Missing Controllers
- [ ] SpecimenController - need full implementation
- [ ] ResultController - need full implementation
- [ ] QualityControlController - not exist
- [ ] CalibrationController - not exist
- [ ] AuditController - not exist
- [ ] BillingController - not exist
