swung0x48 4f2d4c4e83 [MG_Remote, docs] (P7): CONTRACT-P7 carries wave 0's numbers, and device window #1a is on record
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。
