Recurring gas validation errors preventing testnet sync (v1.3.1)

[ahmedbolanta]

Describe the bug

Recurring gas validation errors at multiple block heights preventing reliable sync. Node repeatedly encounters "block gas used mismatch" errors, forcing unwinding and restart loops.

Affected blocks:

• Block 208,657
• Block 4,943,007
• Block 6,033,686
• Additional blocks between 6,031,548 - 6,146,728 (current)

Pattern: Node syncs successfully to a certain block, hits gas validation error, unwinds to last valid state, and repeats indefinitely. This creates challenges for maintaining continuous sync operation..

Current status: Node stuck in unwind loop, unable to progress beyond block 6,031,548.

Steps to reproduce

1. Start v1.3.1 node on Moderato testnet
2. Sync from genesis with --follow wss://rpc.moderato.tempo.xyz
3. Observe node sync until hitting affected block
4. Node fails validation and unwinds

Pattern repeats: Node attempts sync → hits block 6033686 → gas validation fails → unwinds to 6029293 → retries → fails again
