run-harness-bench.sh now loops VARIANTS × BENCH_REPEATS (default 5), writes each
run's row to RESULTS-campaign.md.data immediately (survives interruption), and
aggregates per-variant median/mean/min/max/stdev + median duration into
RESULTS-campaign.md. Frees each run's repo/transcripts after tallying.
A standalone repo (engine vendored as a submodule at the examples commit) that
runs a head-to-head between the builder-adversary and builder-adversary-min
example variants: same task, independent headless runs, both on Sonnet, with
token counts. Includes the roman-numeral test problem and run-bench.sh.
