Bothd7976326bugs passed every unit test while corrupting real frames - state-level assertions cannot see them. This module renders and reads back. A headless EGL-pbuffer harness (no window, no GLFW) linking MobileGL_s directly, registered once per backend under the ctest label integration-gpu, behind the default-OFF option MOBILEGL_BUILD_INTEGRATION_TEST. The platform pre-flight runs the ENTIRE bring-up in a forked child first - MobileGL aborts rather than returning errors on an unusable platform, and the child dying on any signal turns into a clean GTEST_SKIP instead of taking the test binary down. MOBILEGL_ITEST_REQUIRE_GPU makes the label falsifiable: with it set, an unusable harness (or a context that lands on a software rasterizer) is a FAILURE - without it, a CI runner whose driver pinning silently broke reports the same green as one that rendered every frame. Configure-time detection pins the EGL vendor and Vulkan ICD jsons, preferring hardware vendors and never selecting llvmpipe/lavapipe. Scenarios assert on glReadPixels with whole-region pixel counts (a 2x2 quadrant pattern whose signature distinguishes all eight square symmetries; every region predicate reports the first offending pixel): - OrientationScenario: default -> FBO -> default, pinning the transform-flags memo key. Keying GetBaseTransformFlagsRaw on the pre-transform alone fails exactly 3 entries. - StreamedArenaScenario: an untouched streamed vertex buffer must survive transient-arena recycling. Re-enabling only the cross-frame vertex revalidation fails exactly this entry. - CrossFrameBufferScenario + ResidentIndexScenario: cross-frame mutation matrix (SubData, map/unmap, persistent+flush, coherent persistent, orphan, CopyBufferSubData; vertex and index) plus six adversarial resident-EBO constructions. Instrumentation showed the cross-frame EBO memo cannot be made to serve wrong bytes from GL level on this stack (89 entries, 81 accepts, zero divergent slices) - these cases are freshness tripwires, documented as such in-file; the EBO half ofd7976326remains unpinned by a failing test. At the buggy commit72ee7c43the suite fails 4 entries (3 orientation + 1 streamed-arena); atd7976326all 52 pass, 5 consecutive runs, zero flakes, and the default build is bit-for-bit unaffected (unit suite unchanged). Adversarially verified twice, including hostile-platform sweeps (26 configurations, all clean skips) and hand-edits of each production hole in isolation.
