swung0x48 4b54a6f902 [MG_Remote, MG_Backend] (Disaggregated): P5c tx - the server's texture staged shadow
StagedTextureStore (MG_Remote/Server/StagedTextureStore.h), the texture twin of R-11's
StagedShadowStore: keyed by the wire handle (a twin-address key would force glGenTextures
at adopt time), coverage = the whole staged run per (uploadTarget, level), defined-ness
tracked from the respecify hook so sparse chains keep their holes. ApplyTextureUpload
adopts the staged bytes at the last instant they are alive (rule C) through three new
disaggregated-only MGPipeResourceOps members; SyncMipmapsToBackend's four arms read the
store and the descriptor instead of the client's MipmapStorage (texels, extent, target,
defined-ness, dirty); Magma's GenerateMipmap marks the server shadow Defined+GpuDirty
instead of writing the client's level storage (T5). Monolith arms reproduce the pre-tx
expressions character for character behind the same macro discipline as P4a.

Evidence: unit 2147/2147 incl. two named-Fatal death tests and the copies/no-copies
difference suite; DirectGLES.Split 104/104 on WSL GPU; red-once - reverting the adoption
to pointer-dropping turns exactly StagedTextureProductionTest red; the two monolith lane
failures reproduce on the base commit (DirectVulkan.IterationRPProgram203Scenario,
DirectVulkan.F1WireScenario.GenerateMipmapPackedFloatPixels). CONTRACT-P5C section 2.
