Walkthrough

Added security documentation at .jules/sentinel.md detailing a hardcoded password vulnerability found in test comments. Updated tests/inference_test.py comment to recommend sourcing encrypted PDF passwords from environment variables instead of hardcoding credentials.

Changes

Cohort / File(s) Summary

New security finding documentation added detailing hardcoded password in test comments; recommendation to use environment variables (e.g., TEST_PDF_PASSWORD) instead of hardcoded secrets. Test comment updated to reflect this guidance without changing test logic.

⚠️ Potential issue | 🔴 Critical

Do not store the credential literal in the remediation log.

Line 2 still contains the password value ("kanbanery"), which keeps the sensitive secret in-repo. Replace with a redacted placeholder (e.g., "[REDACTED]") and avoid committing raw secret values anywhere, including security notes.

⚠️ Potential issue | 🟡 Minor

Comment at Line 47 is misleading relative to current behavior.

Line 47 says password should come from TEST_PDF_PASSWORD, but commonforms.prepare_form currently does not accept any password input and encrypted PDFs are expected to fail unconditionally. Please reword this to a future-facing note (e.g., “if/when password support is added”) to avoid incorrect implementation assumptions.
