- BlitWireFramebuffers runs colour first. A scaled COLOR|DEPTH blit out of a multisample framebuffer scaled and wrote its colour and then recorded INVALID_OPERATION on its depth, and an X-mirrored one mirrored its colour and left its depth alone - partial effects GL 18.3.1 does not allow. The shape decline (scale, X mirror, cross-format Y mirror) moves into DeclineWireDepthStencilResolveShape, which BlitWireFramebuffers asks for every depth/stencil aspect that would take the multisample resolve arm before any aspect runs; ResolveWireDepthStencil asks it too for any other caller. Default read/draw framebuffers are left to the lambda (a default read is never multisampled; a default draw behind one is the region Fatal, and resolving it early would move its write index).
- The X decline and the cross-format Y decline get their own MGLOG_E_ONCE sites; one site used to cover both, so after the first X decline a cross-format Y decline logged nothing.
- An empty rectangle on one side only (64x48 onto 0x48) is a size mismatch and now takes the scale decline (INVALID_OPERATION) instead of returning silently; empty on both sides stays a silent no-op.
- DirectVulkan.{Split,Spawn}.MsFlip1. forces MGITEST_MAGMA_FORCE_SHADER_DEPTH_RESOLVE=1, so the shader arm min-corner rectangle under a flip runs on this host; split+spawn only and named in MAGMA_SERVER_ENV_KNOB_NO_TCP.
- spawn_lane_parity.py: every server-env-knob tail must match exactly one split key, so a dead or over-broad tail fails the gate instead of riding silently.
- The flipped-resolve case gains a COLOR|DEPTH scale leg (error, colour untouched, depth untouched) and an empty-destination leg (error, depth untouched).
- Red-once, each on split + spawn (+ tcp MsFlip.) and restored: pre-pass disabled -> all five MsFlip/MsFlip1 entries fail "the declined COLOR|DEPTH scale must not have written its colour either" (read {255,0,0,255}, want {0,0,255,255}); round-1 silent empty-side return -> all five fail the empty-destination leg (error 0, want 1282); shader arm handed sx0/sy0 instead of the min corner -> MsFlip1 fails on both arms ("768 of 768 depth values differ from 0.75", "928 of 3072 stencil values are wrong; first at (20, 4): got 255, want 99") while MsFlip. stays green; a dead ".MsFlip2." tail -> parity rc 1 "matches 0 split entrie(s)".
- The split once-sites have no lane red-once: the cross-format Y decline needs a device whose renderbuffer and texture D24S8 map to different VkFormats, which lavapipe is not.
