The captured traces contain per-frame patterns the bench did not exercise, and first measurements show two of them are now the worst remaining multipliers - which is exactly what the missing cases were hiding. mc_pass_switch: the 26.2 snapshot switches render targets 132 times a frame and re-declares draw buffers 198 times. Render-target churn is where a Vulkan backend pays for render-pass breaks and where a tiler pays most on device, and no case measured it. mc_state_toggle: Blaze3D brackets batches with blend toggles - 46 enable/disable pairs and 28 blend-func changes per vanilla frame. mc_tex_param: 26.2 re-sets texture parameters 612 times a frame, almost always to the value already in place, so this measures redundant-parameter filtering. mc_use_program: Sodium switches programs 62 times a frame with a mat4 upload on each, roughly one switch per multi-draw. All four live in the shared case file at the measured per-frame rates, so the desktop harness, the on-device harness and the POST screen's Run Bench report comparable numbers. First desktop measurements (ns/op, native / Espryt / Magma): pass_switch 8877 / 18502 / 13896, state_toggle 1182 / 8526 / 8305, tex_param 42 / 102 / 197, use_program 2182 / 10648 / 5096. The state-toggle multiplier - 7x on both backends - is the largest newly exposed gap and the next optimization target. Unit tests 421/421; the Android JNI translation unit compiles against the extended case set.
