From fc9cfef21daf7d9c3362291afcb8f26951941de7 Mon Sep 17 00:00:00 2001 From: sharonxz Date: Tue, 7 Jul 2026 12:39:38 -0400 Subject: [PATCH 1/5] feat: add H4 security-adjusted reliability experiment script MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Calls real agents (anote-code, claude-code via Anthropic; codex via OpenAI) on all 10 SAMPLE_TASKS with 8 rollouts each. Evaluates generated code for functional correctness (5 tests/task) and security_score, then computes Kendall τ between reliability@5 and security_adjusted_reliability@5 rankings. Saves raw results to data/h4_results.json and generates figures/fig5.

meaningful H4 results Replaces the 10 algorithmic SAMPLE_TASKS (all score security=1.0) with a mixed set: 5 algorithmic + 5 security-sensitive tasks (evaluate_expression, execute_python_snippet, run_shell_command, load_yaml_config, import_module). Security-sensitive tasks naturally elicit eval/exec/os.system/__import__ patterns. Also fixes placeholder detection in extract_code to handle {source_code} responses.
