thejayman77 ba74bbd5aa Snapshot: fog implementation + fidelity tooling baseline (pre bilinear-clamp fix)
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).

# Ch372 Audit Log - Earlier-Capture Six-Draw Expansion
## Integration
- `zsrte6` groups six chronological authentic draws from capture `20260624224047` into two 204-triangle epochs.
It performs one runtime palette/texture fill followed by one CRC-verified resident reuse at CBP `508`.
- Native geometry remains in bounds at x `63..443`, y `40..471`; both feeder lists are 1,843 words.
- Depth-4096 traced integration passes: 446,447 accepted fragments, 373,770 persistent-Z updates, two fresh drains,
zero drops, Z `0/307200`, and color `0/123384`. Request-FIFO high-water is 2,090 then 940.
## Silicon Closure
- The board completed the runtime palette copy, one texture fill, one verified resident reuse, two fresh drains, and
zero fragment drops.
- Board and integration framebuffers are byte-identical at SHA-256
`1b82b94c232907acd037a47c22cbf6262eba6ba73ed25399cb0a4373ef388869`.
- Replay-color is exact at `307200/307200`: 446,447 fragments, 373,770 Z-pass updates, 123,384 covered pixels, and
no uncovered writes.
## Result
Ch372 closes the six-draw earlier-capture expansion on silicon with no RTL, constraint, or fit change.
