llm-assisted-api-debugging-lab 0.1.0

//! Snapshot tests pinning the full rendered report for every known case.
//!
//! These tests exist so that any change to a rule, fixture, or renderer that
//! perturbs user-visible output forces an explicit `cargo insta review` step,
//! rather than silently drifting.
