🚨 Severity: CRITICAL
💡 Vulnerability: Hardcoded password for an encrypted PDF found in test comments (tests/inference_test.py).
🎯 Impact: Accidental leakage of sensitive information or personal passwords.
🔧 Fix: Removed the hardcoded password comment. Added an entry to .jules/sentinel.md documenting this learning.
✅ Verification: Ran uv run -m pytest tests/ to ensure tests pass and changes are correct.

4-4: Consider clarifying the prevention guidance based on current architecture.

The prevention guidance suggests using environment variables or secure vault integrations for testing with protected data. However, based on the relevant code snippets, the codebase currently doesn't support password-protected PDFs at all (it raises EncryptedPdfError), and the TODO comments indicate this is planned future work. The guidance is sound general advice, but could be more specific: since encrypted PDFs aren't currently supported, the immediate prevention is simply to avoid including credentials in any form until the feature is implemented with proper security measures.

📝 Optional refinement for current architecture
-**Prevention:** Avoid committing sensitive credentials or personal passwords in any code artifacts, including comments and tests. Use environment variables or secure vault integrations instead if testing with protected data is required.
+**Prevention:** Avoid committing sensitive credentials or personal passwords in any code artifacts, including comments and tests. Note: The codebase currently does not support password-protected PDFs. When encrypted PDF support is added in the future, use environment variables or secure vault integrations for any credential handling in tests.

handling (e.g., vaults or env vars) is implemented; reference EncryptedPdfError

using secure vaults/env vars once support is added.

4-4: Add trailing newline at end of file.

The file is missing a trailing newline at EOF, which is a common convention in text files.
