# Environment Configuration Audit Report

## Mana Universe Monorepo - Backend Authentication & Configuration

**Date:** December 1, 2025
**Auditor:** Environment Configuration Auditor Agent
**Scope:** All NestJS backends and mana-core-auth service

---

## EXECUTIVE SUMMARY

The monorepo has **CRITICAL PORT CONFLICTS** that will prevent multiple backends from running simultaneously. Additionally, there are inconsistencies in environment variable naming conventions across backends and missing configuration examples for some projects.

**Status:** NEEDS IMMEDIATE ACTION

- 2 port conflicts identified
- 3 naming convention inconsistencies
- 5 backends missing .env.example files
- Hardcoded CORS origins in multiple backends

---

## 1. PORT ASSIGNMENT MATRIX

### Current Assignments (from .env.development)

| Backend            | Port     | Env Variable                | Status      | Conflict |
| ------------------ | -------- | --------------------------- | ----------- | -------- |
| Mana Core Auth     | 3001     | MANA_CORE_AUTH_PORT         | ✓ Unique    | No       |
| Chat               | 3002     | CHAT_BACKEND_PORT           | ✓ Unique    | No       |

| Voxel Lava         | 3010     | VOXEL_LAVA_BACKEND_PORT     | ✓ Unique    | No       |

### PORT CONFLICTS FOUND

1. **Port 3003 - DOUBLE ASSIGNED**
   - Maerchenzauber Backend: `MAERCHENZAUBER_BACKEND_PORT=3003`
   - Picture Backend: `PICTURE_BACKEND_PORT=3003`

2. **Port 3002 - DOUBLE ASSIGNED**
   - Chat Backend: `CHAT_BACKEND_PORT=3002`
   - Nutriphi Backend: `NUTRIPHI_BACKEND_PORT=3002`

### RECOMMENDATION

Reassign conflicting ports:

- Maerchenzauber: Keep 3003, reassign Picture to **3005** or **3006**
- OR reassign Maerchenzauber to **3005** and keep Picture at 3003
- Nutriphi: Reassign to **3006** or another available port
- Mana Games: Currently 3011
- Voxel Lava: Currently 3010

## 2. AUTH ENVIRONMENT VARIABLES AUDIT

### Central Configuration (.env.development)

**PRESENT & CONFIGURED:**

- ✓ `MANA_CORE_AUTH_URL=http://localhost:3001` (Line 16)
- ✓ `DEV_BYPASS_AUTH=true` (Line 59 - Chat only)
- ✓ JWT_PRIVATE_KEY & JWT_PUBLIC_KEY (Lines 19-20)
- ✓ CORS_ORIGINS=... (Line 41)

**MISSING CENTRALIZED:**

- ✗ `DEV_USER_ID` - NOT in .env.development
  - Used hardcoded in Chat: `17cb0be7-058a-4964-9e18-1fe7055fd014`
  - Should be centralized in .env.development

- ✗ `MANA_CORE_SERVICE_KEY` - NOT found in generate-env.mjs mapping
  - Defined for Manadeck in .env.example
  - Not passed to backends via generator

### Backend-Specific Auth Configuration

| Backend      | Auth URL Var       | Dev Bypass          | Dev User ID   | Status          |
| ------------ | ------------------ | ------------------- | ------------- | --------------- |
| **Chat**     | MANA_CORE_AUTH_URL | ✓ Configured        | ✗ Hardcoded   | ⚠ Partially    |
| **Picture**  | MANA_CORE_AUTH_URL | ✗ Missing           | ✗ Not checked | ✗ Incomplete    |
| **Zitare**   | MANA_CORE_AUTH_URL | ✗ Missing           | ✗ Not checked | ✗ Incomplete    |
| **Presi**    | MANA_CORE_AUTH_URL | ✗ Missing           | ✗ Not checked | ✗ Incomplete    |
| **Manadeck** | MANA_SERVICE_URL   | ✗ Not in generation | ✗ Not mapped  | ✗ Not generated |

### ISSUE: Naming Convention Inconsistency

Different backends use DIFFERENT variable names for the same thing:

```
INCONSISTENT:
- Chat uses: MANA_CORE_AUTH_URL (from generate-env.mjs line 95)
- Picture uses: MANA_CORE_AUTH_URL (from generate-env.mjs line 230)
- Zitare uses: MANA_CORE_AUTH_URL (from generate-env.mjs line 300)
- Presi uses: MANA_CORE_AUTH_URL (from generate-env.mjs line 330)

- Manadeck uses: MANA_SERVICE_URL (from generate-env.mjs line 205)
- Manadeck uses: APP_ID (from generate-env.mjs line 206)

- Nutriphi uses: MANACORE_AUTH_URL (from generate-env.mjs line 272)
```

**STANDARDIZATION NEEDED:**
All backends should use consistent naming:

- Recommend: `MANA_CORE_AUTH_URL` (most common)

## 3. ENVIRONMENT VARIABLE MAPPING AUDIT

### Generate-env.mjs Coverage Analysis

| Backend        | .env.example | generate-env.mjs | .env Generated  | Coverage           |
| -------------- | ------------ | ---------------- | --------------- | ------------------ |
| Chat           | ✓ Exists     | ✓ Lines 85-98    | ✓ Will generate | ✓ Complete         |
| Picture        | ✓ Exists     | ✓ Lines 223-243  | ✓ Will generate | ✓ Complete         |
| Manadeck       | ✓ Exists     | ✓ Lines 199-209  | ✓ Will generate | ✓ Complete         |
| **Zitare**     | ✗ Missing    | ✓ Lines 294-303  | ✓ Will generate | ⚠ Missing example |
| **Presi**      | ✗ Missing    | ✓ Lines 323-334  | ✓ Will generate | ⚠ Missing example |
| Mana-Core-Auth | ✓ Exists     | ✓ Lines 57-82    | ✓ Will generate | ✓ Complete         |

**Missing .env.example files:**

- `/apps/zitare/apps/backend/.env.example` - Should document PORT, DATABASE_URL, MANA_CORE_AUTH_URL, CORS_ORIGINS
- `/apps/presi/apps/backend/.env.example` - Should document PORT, DATABASE_URL, MANA_CORE_AUTH_URL, JWT_PUBLIC_KEY, CORS_ORIGINS

---

## 4. HARDCODED VALUES & SECURITY CONCERNS

### Hardcoded in Source Code

**Chat Backend** (`apps/chat/apps/backend/src/common/guards/jwt-auth.guard.ts`):

```typescript
const DEV_USER_ID = '17cb0be7-058a-4964-9e18-1fe7055fd014'; // Line 1
```

- Should be: `configService.get('DEV_USER_ID')`
- Should be in .env.development: `DEV_USER_ID=17cb0be7-058a-4964-9e18-1fe7055fd014`

### Hardcoded CORS Origins in main.ts

**Chat** (`src/main.ts` lines 10-18):

```typescript
origin: [
	'http://localhost:3000',
	'http://localhost:5173',
	'http://localhost:5174',
	'http://localhost:5178',
	'http://localhost:8081',
	'exp://localhost:8081',
	'http://localhost:3001', // Mana Core Auth
];
```

**Picture** (`src/main.ts` lines 11-19):

```typescript
const allowedOrigins = [
	'http://localhost:3000',
	'http://localhost:5173',
	'http://localhost:5174',
	'http://localhost:5175',
	'http://localhost:8081',
	'exp://localhost:8081',
	'http://localhost:3001',
];
```

**Presi** (`src/main.ts` lines 10-17):

```typescript
origin: [
	'http://localhost:3000',
	'http://localhost:5173',
	'http://localhost:5177',
	'http://localhost:5178',
	'http://localhost:8081',
	'exp://localhost:8081',
	'http://localhost:3001',
];
```

**Zitare** (`src/main.ts` lines 10-16):

```typescript
origin: [
	'http://localhost:3000',
	'http://localhost:5173',
	'http://localhost:5177',
	'http://localhost:8081',
	'exp://localhost:8081',
	'http://localhost:3001',
];
```

**RECOMMENDATION:** Move CORS_ORIGINS to .env.development (already exists as CORS_ORIGINS global variable, but not used by all backends)

---

## 5. CONFIGURATION BEST PRACTICES COMPLIANCE

### Configuration Module Setup

| Backend        | ConfigModule             | Validation             | Env File Path | Status     |
| -------------- | ------------------------ | ---------------------- | ------------- | ---------- |
| Chat           | ✓ ConfigModule.forRoot() | ✗ No validation schema | `.env`        | ⚠ Minimal |
| Picture        | ✓ ConfigModule.forRoot() | ✗ No validation schema | `.env`        | ⚠ Minimal |
| Zitare         | ✓ ConfigModule.forRoot() | ✗ No validation schema | `.env`        | ⚠ Minimal |
| Presi          | ✓ ConfigModule.forRoot() | ✗ No validation schema | `.env`        | ⚠ Minimal |
| Manadeck       | ✓ ConfigModule.forRoot() | ✓ Joi schema           | `.env`        | ✓ Complete |
| Mana-Core-Auth | ✓ ConfigModule.forRoot() | ✓ Config service       | `.env`        | ✓ Complete |

**ISSUE:** Chat, Picture, Zitare, Presi lack validation schemas.

**EXAMPLE (Manadeck validation.schema.ts):**

```typescript
export const validationSchema = Joi.object({
	NODE_ENV: Joi.string().valid('development', 'production'),
	PORT: Joi.number().required(),
	DATABASE_URL: Joi.string().required(),
	MANA_CORE_AUTH_URL: Joi.string().required(),
	// ... etc
});
```

## 6. CRITICAL ISSUES SUMMARY

### BLOCKING ISSUES (Fix Immediately)

1. **Port Conflict - 3002**
   - Chat and Nutriphi both assigned to port 3002
   - Cannot run simultaneously
   - **Fix:** Reassign Nutriphi to port 3006

2. **Port Conflict - 3003**
   - Picture and Maerchenzauber both assigned to port 3003
   - Cannot run simultaneously
   - **Fix:** Reassign Picture to port 3005 or Maerchenzauber to 3006

3. **Hardcoded Dev User ID in Chat Backend**
   - `DEV_USER_ID = '17cb0be7-058a-4964-9e18-1fe7055fd014'` hardcoded in source
   - Not configurable via environment
   - **Fix:** Move to .env.development and load via ConfigService

### MAJOR ISSUES (Fix Soon)

4. **Inconsistent Auth Variable Names**
   - Manadeck uses `MANA_SERVICE_URL` instead of `MANA_CORE_AUTH_URL`
   - Nutriphi uses `MANACORE_AUTH_URL` (no underscore)
   - **Fix:** Standardize all to `MANA_CORE_AUTH_URL`

5. **Hardcoded CORS Origins**
   - 4 backends hardcode CORS lists in main.ts
   - Should use environment variables
   - **Fix:** Use CORS_ORIGINS from .env.development

6. **Missing Configuration Examples**
   - Zitare and Presi lack .env.example files
   - **Fix:** Create comprehensive .env.example files

### MEDIUM ISSUES (Improve Quality)

7. **Missing Validation Schemas**
   - 4 backends lack Joi validation schemas
   - No type safety for environment variables
   - **Fix:** Add validation schemas to Chat, Picture, Zitare, Presi

8. **Dev Bypass Auth Not Consistent**
   - Only Chat backend has DEV_BYPASS_AUTH implemented
   - Other backends may lack development bypass mechanism
   - **Fix:** Add consistent development auth bypass pattern

---

## 7. RECOMMENDED ACTIONS

### Phase 1: Critical Fixes (Do First)

```bash
# 1. Fix port conflicts in .env.development
# Change line 122: PICTURE_BACKEND_PORT=3003 → PICTURE_BACKEND_PORT=3005
# Change line 146: NUTRIPHI_BACKEND_PORT=3002 → NUTRIPHI_BACKEND_PORT=3006

# 2. Add DEV_USER_ID to .env.development
# Add after line 59: DEV_USER_ID=17cb0be7-058a-4964-9e18-1fe7055fd014

# 3. Standardize auth URL naming
# Update generate-env.mjs line 272 (Nutriphi):
#   MANACORE_AUTH_URL: → MANA_CORE_AUTH_URL:
# Update generate-env.mjs line 205 (Manadeck):
#   MANA_SERVICE_URL: → MANA_CORE_AUTH_URL:
```

### Phase 2: Configuration Examples

```bash
# Create missing .env.example files:
# - apps/zitare/apps/backend/.env.example
# - apps/presi/apps/backend/.env.example

# Based on .env.development variables and backend requirements
```

### Phase 3: Code Quality

```bash
# Add validation schemas to:
# - apps/chat/apps/backend/src/config/validation.schema.ts
# - apps/picture/apps/backend/src/config/validation.schema.ts
# - apps/zitare/apps/backend/src/config/validation.schema.ts
# - apps/presi/apps/backend/src/config/validation.schema.ts

# Move CORS origins to environment:
# Update main.ts in Chat, Picture, Zitare, Presi to:
#   app.enableCors({
#     origin: (configService.get('CORS_ORIGINS') || '').split(','),
#   })
```
