run_all_to streams every base execution's full trace+delta to disk (no sampling);
main writes evidence/traces.tsv covering 100% of base executions. Verified
end-to-end at the real merge profile:
merge run: 1,000,000 executions / 11,000,000 comparisons, all gates PASS, 288s
evidence: leaves.tsv = 11,000,000 leaves; traces.tsv = 1,000,000 full traces (3.9G)
independent attest: recomputed root a2b27c027f87788f over 11,000,000 leaves ==
claimed; 1,000,000/1,000,000 full traces reconstructed and re-derived to
retained leaves.
