🚨 Severity: CRITICAL
πŸ’‘ Vulnerability: Hardcoded password in tests/inference_test.py used for encrypted PDF test comment.
🎯 Impact: While just a test comment, it violates the zero-hardcoded-secrets policy and can trigger security scanners, leading to noise. Hardcoding secrets in any file (even comments) risks accidental leakage of real credentials if habits aren't strict.
πŸ”§ Fix: Replaced the hardcoded password string with a reference to an environment variable PDF_TEST_PASSWORD. Also added a critical learning to .jules/sentinel.md to document this project convention.
βœ… Verification: Ran uv run ruff check commonforms/ tests/ and uv run pytest tests/ which completed successfully and showed no issues.

Walkthrough

A security finding regarding a hardcoded password in test comments was documented and corrected. A new sentinel entry was created to record the finding, and the corresponding test comment was updated to reference an environment variable instead of the hardcoded secret.

Changes

Cohort / File(s) Summary
Security Documentation & Test Comment Update
.jules/sentinel.md, tests/inference_test.py
Added sentinel documentation recording a hardcoded password finding in test comments. Updated the test comment in test_encrypted_failure to reference environment variable PDF_TEST_PASSWORD instead of hardcoded string.

Poem

🐰 A secret was hiding in plain sight,
In comments where passwords took flight,
Now environment vars keep it safe,
No hardcoded traces to trace! ✨

Document the PDF_TEST_PASSWORD environment variable in project testing documentation.

The environment variable referenced in this comment is not documented anywhere in the codebase (README.md, configuration files, or test setup guides). When the TODO items (lines 54-57) are implemented and the password is actually needed, developers should be able to quickly find where to set or retrieve this value without having to read comments.
