- MGPipeVerifyReadHook honours MOBILEGL_PIPE_VERIFY_CORRUPT: it perturbs the ORACLE after CopyField, and AGAIN after the ID-49 neutral-pack overwrite, because that overwrite replaces the pack half wholesale and CorruptStorage perturbs an array's element 0 - which is the pack half
- until now the knob only ever reached EntryCompare, so every red it could produce was the client thread's where=entry and the hook that runs on the server's apply thread at every backend read had no falsifier at all
- new entry per backend, DirectGLES/DirectVulkan.VerifySplitReadCorrupted., with CORRUPT=GetPixelStoreParameters and VERIFY_FATAL=0 - the field is in the kReadback fill mask, so the client entry compare would otherwise abort the process before the server reached the read
- the case reads the SERVER role's half of its private log alone: with the knob armed a union search over both halves would be satisfied by the arm that is not under test
- PipeStatsWindow.h gains ReadServerLogSince for that
- test.yml grows the matching control step - run the two entries, then re-read both server halves from outside for the where=read report
- measured: 2/2 green, server halves 3 and 2 lines, client halves 0 lines; revert-and-run with the two corruption blocks removed gives 2/2 red and both server halves 0 lines
- the lane goes 1070 to 1072
- 144 commits from 785fed0b0 onward were rewritten to drop the Co-Authored-By trailer the
project forbids; origin/feat/disaggregated moved from 1135c664 to 3c80cd62 (same trees)
- the old->new map is ~/w7/logs/sha-map-20260922.txt; every 7..40-hex citation in the
Disaggregated docs and the MG_Remote contracts that matched an old SHA is replaced by the
same-length prefix of its rewrite; no other content changes
