What

This stacked follow-up adds Windows regression coverage for the full AcquireRegistered path. It targets the head branch of boykopovar/AnyPS5#6097, currently XD3V3LOP3RX/AnyPS5:fix/host-import-probe-use-stamp. The existing boykopovar#6097 test exercises the map-time ImportMappedRanges call directly; this case covers the full acquire flow and final-window BDA coverage. While that build is copying an earlier image mirror, a flush hook changes an unrelated registration. The build then reaches a large registered range with an existing, unheld prefix window. The test verifies that the stale probe does not falsely protect the prefix, the whole-range import replaces it, and the BDA table still covers a view in the final window.

Tested

• Windows x64, MinGW-w64 GCC 15.2.0: agc_driver_graphics_tests builds and agc_driver_graphics passes on fix(graphics): keep discarded import probes from pinning windows boykopovar/AnyPS5#6097 head (5.82 s).
• Red/green isolation: with the production source from fix(graphics): keep discarded import probes from pinning windows boykopovar/AnyPS5#6097 base and the earlier fix(graphics): keep discarded import probes from pinning windows boykopovar/AnyPS5#6097 stale-probe test skipped so this case runs independently, the new assertion fails as expected; restoring the fix(graphics): keep discarded import probes from pinning windows boykopovar/AnyPS5#6097 source makes it pass.
• No physical GPU host-import workload occurred; Vulkan rejected the host import and the test used the copy fallback.
• git diff --check passes.
