benchmark-runner

# Benchmark Runner Standardizes performance comparison methodology: metric selection, test case design, environment capture, result formatting, and tradeoff analysis. Produces reproducible benchmark reports that support informed decisions — not just "A is faster than B" but "A is faster for small inputs while B scales better." ## Reference Files | File | Contents | Load When | | ----------------------------------- | ---------------------------------------------------------------------------------------------------- | ----------------------------------- | | `references/metric-selection.md` | Metric catalog (latency percentiles, throughput, memory, accuracy), selection criteria per task type | Always | | `references/test-case-design.md` | Representative input selection, scale variation, edge case coverage, warmup strategies | Always | | `references/environment-capture.md` | Hardware/software context recording, reproducibility requirements, variance control | Always | | `references/statistical-rigor.md` | Sample sizing, variance measurement, significance testing, outlier handling | Results need statistical validation | ## Prerequisites - Clear candidates to compare (at least 2) -...
