分析算子给结论里以比率存的列和数记换算：契约加 ResultTable.formats、AnalysisResult.value_formats（换算同 [[m:]] 的后缀，另加 pp 表示百分点），各算子逐个填全——可加、乘积拆解的 pct、share；比率拆解的 w_*、r_* 记 pct，mix、rate、total 是比率之差记 pp；波动基线按变化率比较时的 change，趋势的相对斜率；差异检验比率模式的 a_value、b_value 记 pct，diff、ci_lo、ci_hi 记 pp；values 里的 pct_total、top_share、top_k_share、mix_share、rate_share 等。都为空时整项不写，结论和以前一字不差；run 与 recompute 逐字段相同、同输入两次 run 逐字节相同照旧成立（tests/test_analysis_run 的形状检查认这两项可选）
