Development

Running benchmarks

# Inner-loop workflow
mise run bench:dev          # baseline
mise run bench:save         # → target/bench/baseline/  (gitignored)
# ... edit code ...
mise run bench:dev          # measure
mise run bench:compare      # exits non-zero on regression

# Full run — committed reference numbers
mise run bench              # ~10-15 min
mise run bench:save         # → benchmarks/<run-id>/
mise run bench:plot         # regenerates plots/
git add benchmarks/ plots/
