- Local (Gonum): `go test -tags=gonum -bench . -benchmem -run=^$ ./...`
- CI artifacts: download `bench-linear.txt` and `bench-gonum.txt` from the latest workflow run.
- Optional: add historical trend graphs via Benchstat or Codecov integration.
## Sample results (from a recent local run)
Results vary by machine, Go version, and dataset seed. The following run was captured locally and is provided as a reference point.
- Machine: darwin/arm64, Apple M3 Ultra
- Package: `github.com/Snider/Poindexter`
- Command: `go test -bench . -benchmem -run=^$ ./... | tee bench.txt`
Full output:

Notes:
- The first block shows dual-backend benchmarks (Linear vs Gonum) for uniform and clustered datasets at 2D/4D with N=1k/10k.
- The final block includes the legacy single-backend benchmarks for additional sizes; both are useful for comparison.
To compare against the optimized KD backend explicitly, build with `-tags=gonum` and/or download `bench-gonum.txt` from CI artifacts.
