Pull request overview

This pull request adds comprehensive test coverage for evaluation samples (set 2), expanding from 9 to 25 tested samples. The PR introduces new test methods for agentic evaluator samples and improves the sample execution framework to handle samples with main() functions and ensure deterministic test playback.

Changes:

• Added 15 agentic evaluator sample tests and included the previously excluded sample_redteam_evaluations.py sample
• Enhanced sample executor to conditionally call main() functions in sync samples and patch time functions for deterministic playback
• Added timestamp sanitization for evaluation names to ensure consistent test recordings
