🚨 Severity: ENHANCEMENT
πŸ’‘ Vulnerability: The static analyzer was missing yaml.unsafe_load and yaml.full_load in its _SERIALISATION_SINKS mapping, potentially leading to false negatives when tracking untrusted data flowing into these dangerous deserialization functions.
🎯 Impact: Untrusted data flowing into these dangerous functions might not have been correctly marked as UNKNOWN_RAW, limiting the engine's ability to trace its origin or flag its subsequent use correctly.
πŸ”§ Fix: Added yaml.unsafe_load and yaml.full_load to the _SERIALISATION_SINKS frozenset in src/wardline/scanner/taint/variable_level.py.
βœ… Verification: Ran make test to verify changes and ensure all tests passed. Requested code review, and received #Correct#. Recorded the learning in .jules/sentinel.md.

This ensures that the output of these potentially unsafe deserialization
functions correctly sheds validation provenance (becomes `UNKNOWN_RAW`)
in the taint propagation logic.
