Before pushing to GitHub, run:

git status --short --ignored
git grep -n -E "sk-[A-Za-z0-9_-]{10,}|DEEPSEEK_API_KEY\s*=\s*[^\s#].+|SEMANTIC_SCHOLAR_API_KEY\s*=\s*[^\s#].+"

Only .env.example and documentation placeholders should mention environment variable names. Real API keys must stay in the ignored .env file.
