**Status:** Complete  
**Date:** 2026-03-08

   - ✅ Whitelist is now **always enabled** (no opt-out option)

2. **Updated Domain Validation Logic:**

   - Changed error handling: empty domains now cause rejection (fail-safe)
   - Updated security layer documentation (from 2 layers to 3 layers)

3. **Code Impact:**
   - Line 473-476: Removed Valve definition
   - Line 734: Updated docstring
   - Line 779: Removed conditional, made whitelist mandatory

## Configuration Now

### User Configuration (Simplified)

**Before:**

```python
ENABLE_DOMAIN_WHITELIST = True  # Optional toggle
TRUSTED_DOMAINS = "github.com,huggingface.co"
```

**After:**

```python
TRUSTED_DOMAINS = "github.com,huggingface.co"  # Always enforced
```

Users now have **only one parameter to configure:** `TRUSTED_DOMAINS`

### Security Implications

**Mandatory Protection Layers:**

1. ✅ Scheme check (http/https only)
2. ✅ IP address filtering (no private IPs)
3. ✅ Domain whitelist (always enforced - no bypass)

**Error Handling:**

- If `TRUSTED_DOMAINS` is empty → **rejection** (fail-safe)
- If domain not in whitelist → **rejection**
- Only exact or subdomain matches allowed → **pass**

---

## Testing & Verification

✅ **Code Syntax:** Verified (py_compile)  
✅ **Test Suite:** 12/12 scenarios pass  
✅ **Documentation:** Consistent across EN/CN versions  

### Test Results

```
Scenario 1: GitHub Only ........... 4/4 ✓
Scenario 2: GitHub + Raw .......... 2/2 ✓
Scenario 3: Multi-source .......... 5/5 ✓
Edge Cases ......................... 4/4 ✓
────────────────────────────────────────
Total ............................ 12/12 ✓
```

## Breaking Changes (For Users)

### ⚠️ Important for Administrators

If your current configuration uses:

```python
ENABLE_DOMAIN_WHITELIST = False
```

**Action Required:**

- This parameter no longer exists
- Remove it from your configuration
- Whitelist will now be enforced automatically
- Ensure `TRUSTED_DOMAINS` contains necessary domains

### Migration Path

**Step 1:** Identify your trusted domains

- GitHub: Add `github.com`
- GitHub Raw: Add `github.com,githubusercontent.com`
- HuggingFace: Add `huggingface.co`

**Step 2:** Set `TRUSTED_DOMAINS`

```python
TRUSTED_DOMAINS = "github.com,huggingface.co"  # At minimum
```

**Step 3:** Remove old parameter

```python
# Delete this line if it exists:
# ENABLE_DOMAIN_WHITELIST = False
```

## Rationale

### Why Make Whitelist Mandatory?

1. **Security First:** Download restrictions should not be optional
2. **Simplicity:** Fewer configuration options = less confusion
3. **Safety Default:** Fail-safe approach (reject if not whitelisted)
4. **Clear Policy:** No ambiguous states (on/off + configuration)

### Benefits

✅ **For Admins:**

- Clearer security policy
- One parameter instead of two
- No accidental disabling of security

✅ **For Users:**

- Consistent behavior across all deployments
- Transparent restriction policy
- Protection from untrusted sources

✅ **For Code Maintainers:**

- Simpler validation logic
- No edge cases with disabled whitelist
- More straightforward error handling

## Questions & Support

**Q: I had `ENABLE_DOMAIN_WHITELIST = false`. What should I do?**  
A: Remove this line. Whitelist is now mandatory. Set `TRUSTED_DOMAINS` to your required domains.

**Q: Can I bypass the whitelist?**  
A: No. The whitelist is always enforced. This is intentional for security.

**Q: What if I need multiple trusted domains?**  
A: Use comma-separated values:

```python
TRUSTED_DOMAINS = "github.com,huggingface.co,my-company.com"
```
