# 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.
