A new shared code index called RuboCop (Rubidex) provides project discovery, fast parallel syntactic indexing and a worklist fixed point resolver that builds a semantic graph with constant resolution, ancestor linearization, reference tracking and diagnostics. It ships as a Rust core with C API and Ruby gem, powers Ruby LSP, Tapioca and Spoon, and reports 5–10x faster indexing plus 2–4x memory reduction. Incremental indexing and DB caching are in beta.
