-The checkpoint includes model, optimizer, scheduler, support sampler, negative sampler, and resume metadata. Training continued after this snapshot.
+The epoch-25 checkpoint is losslessly split into four files because the training host repeatedly dropped long uploads. Reconstruct it after downloading the repository:
+
+    cat epoch25_parts/checkpoint_epoch_0025.pt.part-* > checkpoint_epoch_0025.pt
+    sha256sum checkpoint_epoch_0025.pt
+
+The reconstructed checkpoint includes model, optimizer, scheduler, support sampler, negative sampler, and resume metadata. Training continued after this snapshot.
