My REQ_DEPTH=1024 reduction was wrong: I sized it off a 478 peak from a SMALL scene. The documented full-f52 replay peak is 6,115 (adjacent frame 3,610; even 2,048 clips) — ch439_timing_convergence_prefit.md. The raster cannot backpressure, so an undersized FIFO SILENTLY DROPS Z-requests -> corrupt frame. The -0.074 fit was on an invalid (drop-prone) config. Restore 8,192 as the correctness baseline. The real timing fix is a registered/skid AR-handshake boundary (arbiter s2_arready combinational -> texcache F_AR), NOT FIFO shrinking. Packaging that for Codex review.

retroDE_ps2 Planning Docs
This directory is the working design scaffold for the PS2 core.
Purpose:
- define the intended repository shape before RTL lands,
- define subsystem boundaries before implementation choices harden,
- document what each block owns, what crosses the boundary, and how we will validate it.
Recommended reading order:
- repo_layout.md
- phase0_checklist.md
- contracts/README.md
- stub_module_plan.md
- wave2_dma_gif_plan.md
- wave25_memory_backed_dma_plan.md
- wave26_multi_beat_dma_plan.md
Relationship to references/:
references/is the research library.docs/is the project-definition layer.
Rule of thumb:
- If a file explains PS2 hardware as it exists, it belongs under
references/. - If a file explains how
retroDE_ps2intends to model, partition, or validate that hardware, it belongs underdocs/.
