Replication Package: Early-Stage Prediction of Review Effort in AI-Generated Pull Requests (MSR 2026 Mining Challenge)

This repository contains the replication package for the MSR 2026 Mining Challenge paper “Early-Stage Prediction of Review Effort in AI-Generated Pull Requests”. It includes scripts to extract creation-time (T0) features from the AIDev dataset, train/evaluate the triage models (LightGBM and baselines), and reproduce the main tables/figures reported in the paper (performance, top-K utility, calibration, robustness checks). The package is anonymized for double-blind review; dataset access follows the AIDev preprint and official download instructions. See README inside the zip for step-by-step reproduction.
