ANVIL-FL: Runtime-Aware Fault Localization for Code Generation and Debugging
Fault localization (FL) is a dominant debugging cost, yet most recent LLM-based FL systems rely on static or coverage-only signals. We introduce <sc>ANVIL-FL</sc> (Anchored Near-failure Value-Informed Localization), a two-turn, tool-free framework that combines LLM reasoning with failure-anchored runtime telemetry. A l...
