P3b/P4b deepening, landing under the P7 program (PLAN-PH-P34B-P7.md 1.2, wave 2-D
package D2). The code half of "按存储属主键控的发射游标与 view 索引重映射" landed in
P4a/P5e; this is the verification half it never had.
TextureViewAliasScenario, four cases: an upload through a layer-restricted view
sampled through the owner and the reverse, each once and again across draw
boundaries so the drain runs three times. Each case asserts on TWO channels at
once - sampled texels AND MGPipeTextureEmitter's SubDataCount / RefusedSubDataCount
/ DrainListSize, read through the new Harness/TextureEmitPeek. The counters are the
load-bearing half: a level that never made it onto the drain list is still uploaded
by the next whole-level respecify, by a glGenerateMipmap or by the monolith sync
path, so the picture comes out right one frame late and a pixel-only case goes green
over the regression on most trees.
Registered in the three GLES split arms, and MOBILEGL_ESPRYT_ENABLE_TEXTURE_VIEW=1
added to MGL_ITEST_GLES_{SPLIT,SPAWN,TCP,TCPDEVICE}_ENVIRONMENT - views are Espryt's
opt-in and without it every case green-skips. The Tcp arm needed the knob on the
TcpServer.Start fixture as well: that lane's server is pre-started rather than
spawned from the client, so it withheld GL_ARB_texture_view and all four cases
SKIPPED while the identical Split and Spawn arms ran.
Red-once (R-16): TextureObjectView::MarkStorageDirtyRegion made to call
PipeNoteLevelDirty on ITSELF instead of forwarding to the storage owner - the
two-cursor shape. TheViewUploadDrainRunsAgainAfterADrawBoundary goes red on both
channels simultaneously (stale owner texels AND SubDataDelta() == 0). The plan
predicted case (a); it is (c) that reds, because the first drain of a texture's life
carries the whole level anyway - recorded in the note.
TheOwnerUploadDrainRunsAgainAfterADrawBoundary is EXCLUDED BY NAME from the split
arms: it is red on all three transports and green under monolith, because an
owner-side resource_subdata moves only the owner's record.Serial and nothing
propagates that to the records viewing it. Cause and the two candidate fix sites are
named in the CMake comment and in notes/p34b/espryt-d2.md. The name stays in every
lane (G14).
