Previous behavior rendered cleanup.requested=false as Cleanup 0/1, making intentionally retained audit evidence look like a failed lifecycle operation. The campaign guide also directed crash-sensitive plans and results to /tmp even though validate_campaign_root() rejects the operating-system temporary tree by default.
Add evidence_lifecycle() in scripts/summarize-benchmark-results.py to label requested disposal, deliberate retention, missing metadata, and requested cleanup failure separately. Rename the generated column to Evidence lifecycle. Point docs/BENCHMARK_CAMPAIGN.md at the ignored durable .worktrees/benchmark-campaign path. Replace the secondary nDCG reference with Järvelin and Kekäläinen's primary DOI 10.1145/582415.582418 and identify exact pairwise Pareto nondominance with Deb et al. DOI 10.1109/4235.996017.
Tests: uv run python -m unittest tests.test_summarize_benchmark_results -v (26 passed); uv run ruff check scripts/summarize-benchmark-results.py tests/test_summarize_benchmark_results.py (passed); git diff --check (passed).
