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>

# Ch374 Audit Log - Earlier-Capture Eleven-Draw Rebind Expansion
|
|
|
|
## Fixture
|
|
|
|
- `zsrte11` keeps Ch373's eight chronological draws as three runtime-CLUT epochs, then adds draws
|
|
`11698`, `11911`, and `11938` as a fourth 142-triangle epoch.
|
|
- The scene runs at native 640x480 and allocates two runtime palette banks: CBP `504` for epochs 0-2
|
|
and CBP `508` for epoch 3. The residency pattern is `fill, reuse, reuse, fresh fill`.
|
|
- Feeder lists contain 1,843, 1,843, 817, and 1,285 words, each below the 4,096-word bridge capacity.
|
|
|
|
## Integration Gate
|
|
|
|
- Depth-4096 integration passes with 524,145 accepted fragments, 431,666 persistent-Z updates, four fresh drains,
|
|
and zero drops.
|
|
- Epoch request-FIFO high-water is 2,090, 940, 1,757, and 100. Exact scoreboards report Z `0/307200` and
|
|
color `0/129883` mismatches.
|
|
|
|
## Board Host Gate
|
|
|
|
- The DE25 completed the two texture fills, two resident CRC checks, four runtime palette copies, all 640 expected
|
|
records, and zero fragment drops.
|
|
- The board framebuffer has 129,883 nonzero words in bounds `(65,41)..(462,470)`.
|
|
|
|
## Silicon Closure
|
|
|
|
- Board and traced-integration framebuffers are byte-identical at SHA-256
|
|
`b44f5e98d79ffa2f451238182f798432edb5c413ea80fea2da6c231a0b4be151`.
|
|
- The complete trace independently replays to the board framebuffer exactly: 524,145 fragments,
|
|
431,666 Z-pass updates, 129,883 covered pixels, zero uncovered writes, and `307200/307200` exact colors.
|
|
|
|
## Result
|
|
|
|
Ch374 closes the first two-palette, eleven-draw earlier-capture expansion on silicon with no RTL, constraint,
|
|
or fit change.
