Teku stayed near head while its data-column gossip counter was zero
· 6 min read
Teku followed Plataberget with a broken data-column gossip decoder. That sounds impossible until you remember PeerDAS has more than one way to recover data.
Across 15 continuously observed Teku nodes, not one data-column sidecar reached the gossip validator during the matched 30-minute window before the patched build arrived. The same 15 nodes submitted 114,383 sidecar messages to that validator in the window after rollout, and 83,684 passed gossip verification.
