thejayman77 ba74bbd5aa Snapshot: fog implementation + fidelity tooling baseline (pre bilinear-clamp fix)
Per-vertex GS fog end-to-end (gs_stub emit incl. persp_emit5, gs_prim_list_feeder
XYZ2->XYZF2 on PRIM.FGE, gs_make_sh3_scheduler_fixture.py F/FGE packing), new fog
TBs, fidelity attribution tooling. Functional baseline before removing the dead
bilinear lerp8 clamps (Codex: 161-node comb loop -> -0.042ns setup fail).

sim/tb/integration

Cross-subsystem integration testbenches that exercise full pipelines end to end. Distinct from the per-subsystem testbenches in sibling tb/<subsys>/ directories — those prove one block in isolation; these prove a chain.

Wave 2 contents

  • tb_bgcolor_via_dma.sv — "programmable BGCOLOR via DMA/GIF" (Milestone A+). Chain: dmac_reg_stub → gif_path_stub → gs_stub → platform_video_stub with four trace sinks. Configures DMAC channel 2, provides a one-qword project-local packet carrying a BGCOLOR register write, verifies the color propagates through to the raster output.

See docs/wave2_dma_gif_plan.md for the Wave 2 scope and the packet format.
