Walkthrough

A critical security issue flagged in a new documentation file: a hardcoded password referenced in a test comment. The test comment was updated to redirect developers to use environment variables and secure secret management instead of embedding passwords in code.

Changes

Cohort / File(s)	Summary
Security Documentation .jules/sentinel.md	New security alert documenting a hardcoded password in test comments, with guidance on using environment variables and secure secret management practices.
Test Comment Update tests/inference_test.py	Updated test comment in test_encrypted_failure to replace hardcoded password guidance with instruction to supply passwords via environment variables or secret manager.

Poem

🐰 A password lurked in comments deep,
In tests where secrets shouldn't sleep,
Now docs stand guard, a sentinel bright,
Guiding devs to do what's right—
Use env vars, keep passwords tight! 🔐

⚠️ Potential issue | 🟡 Minor

Correct the date to match the PR creation date.

The date shows "2025-04-12" but the PR was created on "2026-04-12". This appears to be a typo.
