Methodology: All benchmarks follow strict rules for computational equivalence, dead-code-elimination prevention, idiomatic implementations, and environment-specific execution procedures (AOT / JIT warmup / interpreted). The JSON column applies a "Stdlib Penalty" for languages without a built-in JSON parser (marked with *), and Main Suite results are aggregated using the Geometric Mean.
