+- Plain-CNN P1 is complete, its selector is frozen, and the complete 27-cell
+  P2 audit passes.
+- ResNet X0 and the 19-cell ResNet-20 selector are complete.  The passed
+  selector is tracked at `results/resnet_crossover/p1_selector.json`; formal
+  27-cell R2 is active on timan107 GPU5 and GPU7.
+- Transformer X0 and the 27-cell Transformer-4 selector are complete.  The
+  passed selector is tracked at
+  `results/transformer_crossover/p1_selector.json`; formal T2 remains queued
+  behind R2 on the authorized GTX-1080 pair.
+- A separate single-A6000 hardware profile, restart-safe launcher, and frozen
+  author-code patch stack are available at run-packet tag `a6000-x1-v1` for
+  an independent complete 81-cell replication.
 
 GPU serialization changes calendar time, not the cell registry.  No pending
