[BUG] Sequencer “validation failed” on every new block breaks DA sync

[auricom]

Problem
Since block 452 756 (≈ 20 h after eden-mainnet genesis) the sequencer prints every new block:

ERR failed to broadcast error="validation failed" component=DataSyncService

Because the broadcast fails, it seems the block data is not registered into the p2p store, so full-nodes can no longer retrieve it via P2P, forcing operators to disable P2P entirely.

Issue from the fullnode pov

ev-node-1  | 10:30AM INF headers not yet available from peers, waiting to initialize header sync error="failed to fetch height 452756 from peers: header: not found" component=HeaderSyncService retry_in=1000

Observations

• Issue is not present before height 452 756.
• No code path change was deployed at that height.
• The wrapped error string gives no further context, making it impossible to know which component (signature, state, namespace, …) rejects the blob.
