-core kernel: it is the reference implementation, and the Python and TypeScript surfaces are ports that either dispatch to it (the fast path) or run a byte-identical pure-language fallback. So the sections below read against that reference — how the packages line up, which scorers a kernel actually backs vs which are fallback-only, where the two language ports diverge, and what’s missing where. Everything below the line is generated from the parity manifests + AST (scripts/gen_suite_matrix.py) and verified in CI, so it can’t drift.
Per-package surface
Live counts (introspected from each package) side by side.MCP / Exports / A2A are the same numbers the llms.txt/README gate locks; CLI is the Python command count from the parity manifest.
Compute substrate — the Rust -core kernel is the reference
The Rust / Arrow-native / fused -core kernels are the source of truth for scoring; each language surface either dispatches to the kernel (the fast path) or runs a byte-identical pure-language fallback. This tracks which scorers a kernel actually backs vs which are fallback-only. Sources: Python _NATIVE_SCORER_IDS (arrow bucket kernel) and TS WASM_COVERED_SCORERS (-core WASM), gated as the scorer_kernels api_parity surface.
22 of 24 scorers are kernel-backed (the reference fast path); the other 2 are pure-language fallbacks with no -core kernel.
Cross-language parity (Python ↔ TypeScript)
Per surface: values shared by both languages vs each language’s exclusives. A non-zero Python-only or TS-only is a declared cross-language gap (parity/<pkg>.yaml), not drift — but it is where the two ports diverge.
