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>

# Ch371 Audit Log - Earlier-Capture Runtime CLUT Probe
|
|
|
|
## Scope
|
|
|
|
Qualify the first on-screen PSMT8/perspective cluster from the earlier SH3 capture (`20260624224047`) through the
|
|
runtime CLUT, persistent-Z, and depth-4096 request path.
|
|
|
|
## Fixture and Integration
|
|
|
|
- `zsrte3` retains three authentic chronological draws as two ordered epochs: 68 triangles followed by 136 triangles.
|
|
It fills texture CRC `0x2d9a2fda` once, then proves a resident reuse. The relocated runtime CLUT base is CBP `508`.
|
|
- Geometry is in bounds at x `64..440`, y `44..471`; feeder lists are 619 and 1,231 words, both below the 2,048-word
|
|
staging limit.
|
|
- The traced integration gate passes at depth 4096: 279,804 accepted fragments, 251,464 Z-pass updates, two fresh
|
|
drains, zero drops, Z `0/307200`, and color `0/106017`. Request FIFO high-water is 454 then 2,055, below the fitted
|
|
4096-entry capacity.
|
|
|
|
## Silicon Closure
|
|
|
|
- The board completed one runtime palette copy, one texture fill, one verified resident reuse, two fresh drains, and
|
|
zero fragment drops.
|
|
- Board and traced-integration framebuffers are byte-identical at SHA-256
|
|
`1f060fc17bd0a41e02ae79303b1ffef88a05ff53b2cddde400de1ff2b796bbf4`.
|
|
- Replay-color is exact at `307200/307200`: 279,804 fragments, 251,464 Z-pass updates, 106,017 covered pixels, and
|
|
no uncovered writes.
|
|
|
|
## Result
|
|
|
|
Ch371 closes the first earlier-capture runtime-CLUT probe on silicon. The 2,055-entry peak retains substantial margin
|
|
inside the fitted 4,096-entry request FIFO, so the next rung is an in-cluster draw-count expansion rather than RTL.
