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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Ch401 — fuller 56-draw static frame
Ch401 retains the accepted Ch400 chronological base, one correctly paired ABE draw, two later-scene anchors, and the proven 24-draw central cluster. The result is 56 authentic draws in 28 bounded epochs, within the existing 32-epoch host/testbench limit.
Simulation
- 638,022 fragments fed
- 321,817 fragments passed Z
- 28 ordered drains
- zero request drops, color FIFO overflows, or AXI BRESP errors
- Z mismatches: 0 / 307,200
- color mismatches: 0 / 128,998
Silicon
No RTL changed after the accepted Ch400 RBF. The 28-epoch board run passed all
texture CRC, runtime palette, staging, record-count, drain, and zero-drop gates
and returned rc=0.

Board and simulation are byte-exact over all 307,200 framebuffer words. Ch401 is accepted on silicon and remains displayed through the LPDDR HDMI scanout.
