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>

# Ch370 Audit Log - Runtime CLUT Frame C
|
|
|
|
## Scope
|
|
|
|
Convert the established 24-draw Frame C cluster to host-staged runtime CLUT updates, retaining its distinct relocated
|
|
CBP `504` and proving it on the fitted Ch368 depth-4096 core.
|
|
|
|
## Fixture and Integration
|
|
|
|
- `zsrtc24` contains eight ordered 204-triangle epochs from the authentic Frame C draw set. Epoch 0 fills texture CRC
|
|
`0xcf4cae27`; epochs 1 through 7 verify that CRC as resident texture reuses. Every epoch stages its palette through
|
|
the runtime HPS path.
|
|
- Native geometry stays within x `35..569`, y `9..400`; each feeder list is 1,843 words, below the 2,048-word
|
|
staging capacity.
|
|
- The depth-4096 traced integration gate passes: 346,425 accepted fragments, 167,247 persistent-Z updates, eight
|
|
fresh drains, zero drops, Z `0/307200`, and color `0/73330`. Per-epoch request FIFO high-water values are 948,
|
|
131, 1041, 374, 377, 1855, 606, and 1156. The maximum 1855 stays well below the fitted 4096-entry depth.
|
|
|
|
## Silicon Closure
|
|
|
|
- The board host run completed all eight runtime palette copies, one texture fill, seven resident-CRC reuses, fresh
|
|
ordered drains, and zero fragment drops.
|
|
- Board and traced-integration framebuffers are byte-identical at SHA-256
|
|
`6614d7211b9a668cfeda12e4fa2d6f469d3ee4d3a10bdf56c0119b35f93c7803`.
|
|
- Replay-color is exact at `307200/307200`: 346,425 fragments, 167,247 Z-pass updates, 73,330 covered pixels, and
|
|
no uncovered writes.
|
|
|
|
## Result
|
|
|
|
Ch370 closes Frame C on silicon with runtime CLUT staging and persistent Z. No RTL, constraint, or Quartus fit change
|
|
was required; the current Ch368 core carries this third runtime scene within its measured request-FIFO envelope.
|
|
|
|
## Three-State Motion Extension
|
|
|
|
- The same loaded core ran `zsrtm28 -> zsrtc24 -> zsrtb24 -> zsrtm28 -> zsrtc24 -> zsrtb24`, with color/Z reset and
|
|
the appropriate texture and runtime palette staged at every frame boundary.
|
|
- The six boundary dumps match the independently closed integration framebuffers exactly: M28 dumps 0 and 3 hash to
|
|
`fdff2f34eac22ee140b64d8fac129627549bbb0f6db37d4b91807a9058e47a04`; Frame C dumps 1 and 4 hash to
|
|
`6614d7211b9a668cfeda12e4fa2d6f469d3ee4d3a10bdf56c0119b35f93c7803`; Frame B dumps 2 and 5 hash to
|
|
`3191d75983e72a158f91f15cc1f57b6ff7c5e40d5bbb4a49957db06db4e2fded`.
