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>

Ch404 — chronological character-detail tail
Ch404 appends the next 36 authentic opaque draws after the accepted Ch403 frame. Thirty-five staging-safe epochs preserve dump order and cover the character/lower-body region without changing RTL or requiring another fit.
Fixture and infrastructure
zsrt139b1: generated 35-epoch detail tail.zsrt139b2: merged Ch403 base plus the tail, 75 epochs total.tools/merge_runtime_sched.py: concatenates accepted runtime-CLUT fixtures without regenerating or changing their staged records.- Host and shared-testbench epoch ceilings increase from 64 to 128; staging RAM remains 2,048 words and the FPGA image is unchanged.
RTL verification
- 667,279 fragments fed; 351,074 passed persistent Z.
- 75 ordered markers and drains.
- Zero request drops, color FIFO overflows, or AXI response errors.

The tail adds 1,003 nonblack pixels over Ch403. Against the resized PCSX2 frame, RGB MAE improves from 23.8474 to 23.7846 and RMSE from 34.8791 to 34.6956. This is a bounded character-detail gain, not the missing environment or fog solution.
Silicon acceptance
The timing-clean Ch403 RBF was retained. The board completed all 75 epochs
with every texture CRC, runtime palette checksum, staging count, record count,
fresh drain, zero-drop, and bus-error gate clean; the host returned 0.
The 307,200-word board framebuffer is byte-for-byte identical to RTL and has
the same SHA-256
