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).

Ch375 Audit Log - Fourteen-Draw Post-Rebind Residency

  • zsrte14 extends Ch374 with three later, on-screen draws using CBP 508, producing a five-epoch fill, reuse, reuse, rebind, reuse runtime-CLUT sequence at native 640x480.
  • Integration passes with 529,836 accepted fragments, 434,596 Z-pass updates, five fresh drains, zero drops, exact Z 0/307200, and exact color 0/132063. Request-FIFO high-water is 2,090, 940, 1,757, 100, and 81.
  • On the DE25, both palette banks, both texture fills, all 816 expected records, and all drop gates pass.
  • Board and traced integration framebuffers are byte-identical at SHA-256 3a4b8f12a08dd0a5e9872675a1dd7cf2d767b76c71def1c1f4398f8c89da104d.
  • Replay-color is exact at 307200/307200: 529,836 fragments, 434,596 Z-pass updates, 132,063 covered pixels, and zero uncovered writes.

Ch375 closes the fourteen-draw post-rebind residency expansion on silicon without RTL, constraint, or fit changes.
