@pasindutennage-da It all looks good to me, but leaving the approval up to @rautenrieth-da

Thanks, looks good to me! I left some minor comments. The only part where I'm unsure is https://github.com/hyperledger-labs/splice/pull/3214/files#r2549005245, please double check with Nicu before merging.

for {
  json <- storage.querySingle(queryAction, "get-validator-internal-config")
} yield {
  val decodeResult = json.as[T]
  // ...
}

if you want to avoid some of the vals.

The changes in this file are unnecessary. If possible, try to avoid them as it only leads to noise in the git log and merge conflicts for people that happen to work on the same file.
