+# ISA VGG8/CIFAR-10 device checkpoints
+
+This package selects one validation-best VGG8 checkpoint for each of ReRAM,
+PCM, STT, and Flash. FeFET is not part of this checkpoint group.
+
+| Device | Trial | Best epoch | Best validation accuracy |
+|---|---:|---:|---:|
+| ReRAM | 2 | 190 | 87.50% |
+| PCM | 12 | 177 | 92.03% |
+| STT | 17 | 170 | 89.22% |
+| Flash | 10 | 182 | 90.14% |
+
+The four staged files are byte-identical to their selected source checkpoints.
+`SHA256SUMS` records the verified hashes. The values above are validation
+accuracies; a full-test metric will only be added after evaluation with the
+canonical release runtime.
