## Detailed Verification Results

### ✅ 1.1 Hardcoded Test Secret Removal - **FIXED**

**Repository**: mahavishnu
**File**: `mahavishnu/core/permissions.py`

**Status**: ✅ **VERIFIED FIXED**

**Current Implementation** (lines 111-120):

```python
# Critical security: Never use hardcoded secrets
if not config.auth_secret:
    raise ConfigurationError(
        "MAHAVISHNU_AUTH_SECRET environment variable must be set. "
        "Generate a secure secret with: python -c 'import secrets; print(secrets.token_urlsafe(32))'"
    )

self.secret = config.auth_secret
```

**Evidence**:

- Raises ConfigurationError if auth_secret not set
- No fallback hardcoded secret
- Clear error message with secret generation command
- **Security best practice**: ✅ IMPLEMENTED

### ✅ 1.2 XSS Vulnerability Fix - **FIXED**

**Repository**: splashstand
**File**: `splashstand/adapters/admin/sqladmin.py`

**Status**: ✅ **VERIFIED FIXED**

**Current Implementation** (lines 464-476):

```python
@depends.inject
@login_required
@expose("/video_preview/<filename>")  # type: ignore
def _video_preview(
    self,
    filename: str,
    storage: Storage = depends(),
) -> Markup:
    # XSS Prevention: Escape filename before HTML interpolation
    safe_filename = escape(filename)
    safe_url = escape(storage.media.get_url(filename))
    return Markup(
        '<video width="1024" height="576" controls'
        ' poster=""><source src="{}" type="video/mp4">'
        "Your browser does not support the video "
        "tag.</video>".format(safe_url)
    )
```

**Evidence**:

- Uses `escape()` from markupsafe to sanitize user input
- Both filename and URL are escaped before HTML interpolation
- **Security best practice**: ✅ IMPLEMENTED

______________________________________________________________________

### ✅ 1.3 CSRF Protection Implementation - **IMPLEMENTED**

**Repository**: splashstand
**File**: `splashstand/adapters/admin/routes.py`

**Status**: ✅ **FULLY IMPLEMENTED**

**Implementation Details**:

- `generate_csrf_token()` function
- `setup_csrf_protection()` function
- `CSRFMiddleware` class with double-submit cookie pattern
- Proper validation for state-changing requests

**Key Features**:

- Secure token generation
- Cookie-based token storage
- Middleware integration with Starlette
- State-changing request validation

**Evidence**:

```python
class CSRFMiddleware(BaseHTTPMiddleware):
    """Middleware to enforce CSRF protection on state-changing requests."""
    # Full implementation with cookie_name, secret_key, etc.
```

**Security best practice**: ✅ IMPLEMENTED

______________________________________________________________________

### ✅ 1.4 Cache Checksum Vulnerability Fix - **FIXED**

**Repository**: jinja2-async-environment
**File**: `jinja2_async_environment/bccache.py`

**Status**: ✅ **VERIFIED FIXED**

**Current Implementation** (lines 66-81):

```python
def get_source_checksum(self, source: str) -> str:
    """Generate SHA-256 checksum for template source.

    Uses cryptographic hash function (SHA-256) instead of Python's built-in
    hash() to prevent collision attacks and ensure consistent checksums across
    different Python versions and platforms.
    """
    import hashlib

    return hashlib.sha256(source.encode("utf-8")).hexdigest()
```

**Evidence**:

- Uses `hashlib.sha256()` (cryptographic hash)
- Not using weak `hash()` function
- Comment explains the security fix
- **Security best practice**: ✅ IMPLEMENTED

______________________________________________________________________

### ⏳ 1.5 Empty MCP Shell Repository Decisions - **ACTION REQUIRED**

**Status**: ⚠️ **DECISION NEEDED**

**Empty Repositories Identified** (4 total):

1. `porkbun-dns-mcp` - 0 files
1. `porkbun-domain-mcp` - 0 files
1. `synxis-crs-mcp` - 0 files
1. `synxis-pms-mcp` - 0 files

**Option A: DELETE (Recommended)** ⭐

- **Effort**: 1 hour
- **Rationale**: Clean up ecosystem, reduce confusion
- **Action**:
  ```bash
  # Remove from repos.yaml
  # Archive to .archive/empty-mcp-shells/
  # Update documentation
  ```
- **Impact**: Immediate cleanup, no confusion

**Option B: IMPLEMENT WITH FASTMCP**

- **Effort**: 64 hours (16 hours per repo)
- **Rationale**: Full MCP server implementations
- **Requirements**:
  - API documentation access for each service
  - FastMCP scaffolding for each
  - Testing and validation
- **Impact**: Time-consuming, may not be high priority

**Recommendation**: **DELETE** - These serve no purpose as empty shells

env = AsyncEnvironment(
    loader=loader,
    autoescape=False,
    enable_async=True  # CRITICAL for async rendering
)

# Template inheritance works correctly
