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).

Ch383 Audit Log - Thirty-Four-Draw Third-Binding Extension

  • zsrte34 extends the native-640x480 persistent-Z scene to 34 authenticated draws in 13 epochs, retaining the three runtime texture/CLUT bindings at relocated CBPs 500/504/508.
  • Local depth-4096 integration passes with 647,303 accepted fragments, 500,072 Z-pass updates, 13 fresh drains, zero drops, exact Z 0/307200, and exact color 0/166963.
  • The DE25 host run completed all 1,899 expected records with all palette and texture-fill checks passing and no fragment drops. Its framebuffer bounds were (46,3)..(634,473) with 166,963 nonzero pixels.
  • The board dump and the independently traced integration framebuffer are byte-identical at SHA-256 61169f615b327f235405cabb19fff38d3b336c359cd30c498357b6b16338bd19.
  • Replay-color is exact at 307200/307200: 647,303 replay fragments, 500,072 Z-pass updates, 166,963 covered pixels, and zero uncovered writes.

Ch383 closes the 34-draw, 13-epoch extension on the timing-closed core. No RTL, SDC, QSF, or Quartus fit changed.
