Review follow-up on PR #4: run --quantization fp8 through the served path on the 3090 (the flag issue 1 validated for capacity), add the untested 3-reference fixture, and measure all counts. Capacity: confirmed — all of 1/2/3/4 references fit and run (4-ref 44.1-44.4s, server peak 23,522MB, nvidia-smi max 23,983MiB; Marlin W8A16 is faster than BF16, 3.3x the Diffusers nocache baseline). Quality: every fp8 output is structurally broken on this commit and card (~97% transparent RGBA, grey RGB, PSNR 7-9dB) — on the edit path at every reference count and on T2I alike (issue 1's fp8 artifacts reinspected: same collapse; that run validated rc+image, not output structure). img_mlp exclusion does not fix it; transformer-only fp8 also collapses, pinning the culprit on the Marlin-quantized DiT. 3090 verdict stays not-built; upstream fix order is fp8 output correctness before any capacity role for it.
