CONTRACT-P7: the lane counts (magma-split 73 / spawn 52 / tcp 54; full-suite 510 x 3 with one StreamLink x Magma red), the census baseline (79 abort sites over 20 files, 43 family words, 0 unmarked), the ratchet baseline (186 = p7-magma 101 / espryt 14 / both 60 / core 11; espryt's clearable count is 9) and the @P7 count (15 sites / 4 files) replace the 待填 markers. Device window #1a (Redmi 2f7cbe2e, APK p7w1-d260f110, reboot-clean): E0a monolith 39/39 deterministic, three below threshold on monolith itself (create-indirect, 1.21.11 main-menu, iris-photon - Adreno refuses its pipelines with VK_ERROR_UNKNOWN); E0a inproc: OpenRA 0.976494 (run-ahead) / E1 lockstep 0.988998 - both historical numbers were OpenRA, and its client log shows a TextureResources verb answered from caps generation 0 (package F1); 26.3 / create-* SIGSEGV in the replayer's memcpy on BOTH backends and with the persistent-map push off (package X1); iterationt x2 die by name on Magma:mipmap-shader-format-or-shape (package B); bsl-esc-menu hits scudo OOM under inproc. Gate 3's denominator is 36; run-ahead and present credit are off the suspect list.
E1 · MOBILEGL_IPC_RUN_AHEAD=0 的 lockstep 对照
集合 = E0a 的分歧 / 死亡 case（OpenRA、26.3、create-instancing、bsl-esc-menu-854、iterationt）+ 两个对照（minecraft-1.21.4-in-world、sodium-in-world），DirectVulkan × inproc × pbuffer × 1 遍。
臂证明（arm-proof.txt，7/7）：每例 run-ahead ARMED 计数 0，Config: IPC 行只有 run-ahead=0。这就是 runbook §5 说的「一条在 + 一条不在」；running lockstep 这句在 RUN_AHEAD=0 下本来就不打。每例退出码非零是 --require-inproc 门要求 run-ahead=1 的已知副作用，结果与归档照常可用（E1.log）。
| case | ARMED（E0a） | lockstep（E1） | 读法 |
|---|---|---|---|
| OpenRA | 0.976494 | 0.988998 | 仍分歧；幅度变小。= 历史第二个观测值。run-ahead 不是原因，只影响首个 CapsSnapshot 前丢掉多少发射 |
| 26.3 | SIGSEGV | SIGSEGV | 与 run-ahead 无关 |
| create-instancing | SIGSEGV | SIGSEGV | 同上 |
| bsl-esc-menu-854 | SIGABRT（scudo OOM） | SIGSEGV | 内存上限附近的不同死法 |
| iterationt | Fatal{UnmigratedVerb,"Magma:mipmap-shader-format-or-shape"} |
同 | 确定性具名拒绝 |
| 1.21.4-in-world（对照） | 0.9999956 | 0.9999956 | 同 |
| sodium-in-world（对照） | 0.9999938 | 0.9999938 | 同 |
判别（runbook §5 的那一行）：不变 ⇒ run-ahead 整条线出局，原因在 server 的内容路径 / 能力协商。 E2（credit 扫描）据此不跑。
