WeSCE - Complete Clearance: leaderboard

Part of WeSCE (Zhang et al., 2026): the percentage of programs left with near-zero residual vulnerability risk after a model edits them under functional-only instructions, averaged over feature addition, feature removal, bug fixing and refactoring. Risk combines CodeQL, Bandit and Atheris findings; higher is better.

Metric: Complete clearance rate (%; share of edited programs whose residual risk after the edit falls below 0.01; 400 executable real-world-derived Python programs edited under functional-only (weak-security) instructions, 100 each for feature addition, feature removal, bug fixing and refactoring; risk before and after the edit aggregates CodeQL and Bandit static findings and 90-second Atheris fuzzing findings, severity-weighted and size-normalized, through LogSumExp; mean of the four task rates; top-p 0.9, top-k 20). Source: arxiv.org. Saturation forecast: Around April 2027. 8 models tracked.
