From Codebase to Culprit (C2C): Reducing the Search Space for Bugs with Semantic Retrieval and Hierarchical Reinforcement Learning

Ankur Garg, Corey Yang-Smith, Rishav Rishav et al. · 2026

We introduce C2C (From Codebase to Culprit), a framework for precise bug localization that progressively reduces the debugging search space across multiple levels of granularity: files, functions, and lines of code. To mirror developer's natural top-down debugging workflows, C2C integrates semantic retrieval and Hierar …

REBOOT: From Failure to Recovery - A Dataset and Benchmark for Precision Assembly

Nana Yaw Owusu Ofori-Ampofo, Samira Ebrahimi Kahou, Joseph Thekinen · 2026

Robot learning policies fail in characteristic ways: they stall in uncertain states, drift during contact-rich alignment, and miss targets by millimetres in precision tasks. Yet training datasets consist largely of successful demonstrations, while real-world benchmarks often reduce performance to binary success. This l …
