# Loki Mode Multi-Agent Patch
# Attempts: 1

Based on the architect's analysis and my knowledge of pytest's junitxml.py structure, I'll generate a patch that adds the hostname and timestamp properties to the generated JUnit XML reports:

Wait, let me reconsider - the patch above has issues. Let me generate a cleaner, correct patch based on the typical structure of pytest's junitxml.py:
