evidence: digest reads DFG Re20 result.json of schema 1 or 2

final_physical_digest.py indexed [0] on the bare-list (schema 1) native
receipt. v4_cases() accepts schema 1 and the versioned schema-2 object
and rejects others. Existing outputs and final-physical-digest.json are
unchanged; that digest records the previous postprocessor hash, so a
rerun with this version is a new digest.

+待 Grok 独立复核：750e8a4 本轮六例物理验证
+==========================================
+
+固定候选 `750e8a483ec47dcf472e528edc1cf2936f0e7e83`，工作树 `/home/frank14f/CelerisLab-release-prep-20261020` 干净。六例全部完成、退出码 0、无超时；调度器和六个子进程均已消失，最终 `nvidia-smi` 无计算进程。206 个源码/测试/文档哈希与启动 manifest 一致，各例运行前后 source map 相同，原生结果与外部摘要一致；V2 原生源码捕获及 runner 哈希也一致。V4 采用外部 manifest 绑定，没有冒称 runner 内部具备同样 provenance。没有新实验、阈值变更、源码变更、main 合并或公开发布。
+
+六例状态及进程墙钟秒数：V2 zero refined `periodic` 511.409，zero uniform `periodic` 325.254；fixed refined `driven_diagnostics_complete` 530.173，fixed uniform 同状态 333.016；V4 refined `NOT_STEADY` 315.714，uniform `NOT_STEADY` 114.183。墙钟包含初始化和观测开销，仅用于执行记录，不能作正式性能比较。
+
+**V2 zero：MRT、unshifted，均达到 t*=300。** 每例 3480 条 history；refined 1.2M steps，uniform 2.4M steps。各提取 14 个 t*>250 的周期，末五周期全部原生周期门槛通过，各自与冻结参考比较通过。
+

+
+`matched_case_pass=false` 原样保留：四次 V2 调用均选择单 case，runner 只有 `--case both` 的两结果原生比较分支才赋值这一字段。它不等于 zero 的各自周期或参考比较失败，也不能由执行者自行改为 true；本轮没有运行该 paired-case 原生比较。fixed 没有官方 DFG 参考 verdict，完成执行不等于物理验收。
+
+**Fixed Jet 健康与 CV。** 两例达到 t*=300，五个 250–300 诊断窗均完整。原健康规则为 physical leaf 数据及 impulse 有限、rho_min>=0.5、rho_max<=1.5、Mach<=0.2。所有 3480 条 history 均有限，观测数值如下。
+
+| 指标 | refined | uniform |
+|---|---:|---:|
+| 全序列 rho min / max | 0.994218661 / 1.004163150 | 0.993391573 / 1.004678726 |
+| 全序列 max Mach | 0.0422925943 | 0.0421810197 |
+| mass t*=0.5 / t*=300 | 0.8931541481 / 0.8931214909 | 0.8936680602 / 0.8936524063 |
+| 上述端点质量相对变化 | -3.65640e-5 | -1.75164e-5 |
+| t*=290–300 mass ptp/mean | 8.40337e-5 | 6.31000e-5 |
+| 290–300 Cd / Cl 均值 | 3.184020005 / -0.580990812 | 3.182612828 / -0.582235721 |
+
+CV 各 501 个端点，间距 t*=0.02，积分区间 290–300（root time 40000）。排除首端点之前的 impulse，只累加后 500 个区间；root reaction impulse refined=(254.721600438,-46.479264945)，uniform=(254.609026243,-46.578857642)。两条矩形轮廓 refined 为 (48,44,160,120)/(44,36,180,128)，uniform 的 x 坐标均加 0.25。以原式 `J_CV=-ΔP-∫outward_momentum_flux dt`，残差为 `J_CV-J_raw`，系数除以 `duration*0.5*U_root²*D_root=80`。这里是 wall+aperture 原始流体对物体反作用，不是已修正的 nozzle thrust。
+
+| 动量残差系数 (x,y) | refined | uniform |
+|---|---|---|
+| 内轮廓、stride1 | (2.24958e-4,-1.00611e-4) | (1.78190e-4,-7.24811e-5) |
+| 外轮廓、stride1 | (7.88038e-5,-4.35879e-5) | (-8.30841e-5,-1.99246e-5) |
+| 外减内 | (-1.46155e-4,5.70231e-5) | (-2.61274e-4,5.25565e-5) |
+| stride2 相对 stride1 最大分量差 | 1.18312e-5 | 2.19402e-5 |
+| stride4 相对 stride1 最大分量差 | 4.44884e-5 | 6.26044e-5 |
+
+CV 未定义验收门槛，以上仅为离线积分诊断。质量记录缺少 raw `mass_into_fluid` Jet 源账本，无法扣除质量源判断闭合。`ΔM+∫outward_mass_flux dt` 仅是表观质量源：refined 内/外=-0.0172316912/-0.646617293 root mass；uniform=3.519017515/3.575029022。相对初始 CV 库存分别 (-2.37505e-6,-5.74501e-5)/(4.84891e-4,3.17573e-4)。轮廓间质量差异保留供审查，不能据此宣称质量闭合通过。
+
+**V4：SRT，无 Jet，t*=60。** uniform 480k/refined 240k steps，各 120 个样本。末窗 t*=50–60 共 21 点；drift 是原 runner 的 `abs(OLS slope per t*)*10`。
+
+| case / 指标 | 末窗 range | 原 range 上限 | 末窗 drift | 原 drift 上限 |
+|---|---:|---:|---:|---:|
+| refined Cd | 9.86614e-4 | 0.002 | 4.68834e-6 | 0.0004 |
+| refined Cl | 6.95374e-5 | 6e-5 | 3.28188e-6 | 1.2e-5 |
+| refined p_diff | 1.45066e-4 | 4e-5 | 9.28999e-6 | 8e-6 |
+| uniform Cd | 1.19061e-3 | 0.002 | 1.60374e-4 | 0.0004 |
+| uniform Cl | 7.93289e-5 | 6e-5 | 5.92289e-6 | 1.2e-5 |
+| uniform p_diff | 1.27157e-4 | 4e-5 | 2.80735e-5 | 8e-6 |
+
+两例均有 Cl range、p_diff range/drift 超限，保持 `steady=false,status=NOT_STEADY,verdict=null`。末窗均值 refined=(Cd 5.588876919,Cl 0.010732806,p_diff 0.117811546)，uniform=(5.586439289,0.010680915,0.117402607)。原区间 Cd=[5.57,5.59]、Cl=[0.0104,0.011]、p_diff=[0.1172,0.1176]；refined 压差均值在区间外，uniform 均值在区间内，但均不能越过稳态 gate。
+
+120 点全序列（t*=0.5–60）存在初始瞬态和反复起伏：refined Cd/Cl/p_diff 的增量符号变化次数为 82/80/82，uniform 为 79/78/81；末窗仍为 13/13/14 和 12/13/11。末窗有符号 OLS slope per t* refined=(-4.68834e-7,-3.28188e-7,-9.28999e-7)，uniform=(-1.60374e-5,+5.92289e-7,-2.80735e-6)。这只是当前采样分辨率下的非单调时序描述，不能确定振荡频率、物理/数值根因，也不是发散或瓶颈结论。完整 JSON 保留全序列及逐 10 t* 窗统计。边界偏差仍为 pressure-NEQ/neq_extrap outlet 与 local Zou-He inlet，不能称为原始 do-nothing DFG 边界。
+
+**复核边界与证据。** 本轮不是发布通过：短套件仍为 767 passed/24 failed/1 skipped；V1 历史 pin 阻塞，V3 四例原 TG dry-run 均被 frozen-source guard 拒绝、尚无 CUDA 计算或 TG 结果；未接纳待修订 `56004f44`，没有修改 dtype/NumPy/数值核心。下一步由 Claude 提交修订和解释、Grok 独立复核，再由集成任务接受明确通过审查的 SHA。
+
+原始证据根 `/home/frank14f/CelerisLab-release-evidence-20261020/physical-750e8a4/followup-queue`。`final-physical-digest.json` 约 99 KB，含全部六例原生小摘要、门槛、CV 抽稀结果、源/输出哈希、进程检查和限制；后处理脚本 `final_physical_digest.py` 不导入或运行模拟器。原始 history/log 只保留在 Horsea，没有上传巨量日志。
