## Question

A junior developer submitted this pull request. Write code review comments that are:
- Technically accurate
- Educational (helps them learn, not just tells them what's wrong)
- Kind but honest
- Actionable

```python
# PR: Add user authentication

def login(user, pw):
    # get user from db
    u = db.query(f"SELECT * FROM users WHERE name='{user}'")
    if u == None:
        return False
    # check pw
    if u.password == pw:
        session['user'] = u.name
        session['admin'] = True  # give admin access
        return True
    return False

def is_admin(user):
    return session.get('admin', False)
```

## Methodology

- **10×10 Blind Peer Matrix:** All models answer the same question, then all models judge all responses.
- **5 Criteria:** Correctness, completeness, clarity, depth, usefulness (each scored 1–10).
- **Self-judgments excluded:** Models do not judge their own responses.
- **Weighted Score:** Composite of all 5 criteria.
