제목	GPU follow-up 20260720T030001Z: 1 inconclusive, 1 positive
궁금했던 점	What did the validated GPU3 experiments establish, and what remains unresolved?
해본 것	- mlir-fft-compiler: safely inspected and stopped the legacy square-only compile; no new rectangular/tiled timing artifact. Exploratory artifact preserved. - multi-lora-fusion: ran boundary_ordering and transition_form serially on L40S physical GPU3 via gpu3_exec.py using an isolated commit snapshot.
당시 조건	Codex-owned GPU3 follow-up. Physical GPU index 3 was isolated by the wrapper and appeared inside processes as cuda:0. Canonical worktrees were left untouched.
실제 결과	mlir-fft-compiler outcome inconclusive: expected rectangular/tiled artifact was not produced; exploratory occupancy artifact only. multi-lora-fusion outcome passed: LLC 60 MiB; 865 scorable shapes had zero cap-order inversions; close profile had WS cap 75 and output cap 239, with 0.261x graded WS rise and 0.791x output step. Far-tail transition showed N=384 resident to N=448 spilled, output/LLC 0.400 to 0.467, 1.638x jump. Single-knee max relative error 45.0–55.6%; two-boundary mean/max relative error 38.1%/48.4% on the far tail.
왜 그랬는지	The multi-LoRA GPU evidence supports sequential two-boundary behavior and rejects a single-knee model for this far tail. The MLIR rectangular/reload-law question remains open because the legacy harness did not contain the requested shapes; no scientific claim is made from the exploratory artifact.
다음에 기억할 것	For cache-capacity models, measure both nested tensor boundaries and score held-out tails; a sharp output-tensor transition can coexist with a graded working-set rise, while an unmodified square-only harness cannot answer rectangular reload-law claims.
언제 맞는지	Only the recorded repositories/commits, fp32 multi-LoRA GPU3 run, and exploratory MLIR compile environment. Timings are device- and shape-specific.
