Summary

• benchmarks/scifact/hybrid-vs-rerank.json is regenerated from the current hybrid and rerank reports. Its candidate run ID now matches rerank-selected.json. Every other comparison under benchmarks/ already matched its reports. Deltas, confidence intervals, and p-values are unchanged. The current compare path also stores the statistics recipe on this newly written file.
• Signed figures that round to zero keep their sign, so the SciFact chunked-minus-ablation nDCG@10 mean renders as -0.000 instead of +0.000.
• Links in docs/results.md use ../ so they resolve from docs/. A test checks every relative link in README.md and docs/*.md.
• The getting-started Docker pointer now goes to the architecture note, because the README no longer has a Docker section.
• The regression note says reports committed before the rename keep "versions": {"ragbench": ...} alongside the legacy schema IDs.

Test plan

• ruff check and ruff format --check
• mypy
• pytest with coverage (89.09% with the dense extra installed locally)
• Comparison run IDs match the reports they name
• Relative documentation links resolve
