The cause was a divergence from the 3SF-mini prototype. We were fetching the validator's latest finalized from the highest finalized block across all chains, instead of from the current head.

The fix was merged to the spec yesterday by another client team, and we ported it to ethlambda today. New image is already published.
Great to be here!
