Previously, without undo data available, `blockToJSON` could not extract prevout details or fees, causing `BlockToJsonVerbosity3` to perform identical work to `BlockToJsonVerbosity2`.",
  "problem": "The `BlockToJsonVerbosity3` benchmark did not actually exercise verbosity 3 logic (prevouts and fees) due to missing undo data, rendering the benchmark unrepresentative of real-world RPC execution.",

This fixes an inaccurate benchmark for developers optimizing verbose `getblock` serialization. The PR has a verified Tested ACK from ismaelsadeeq and is ready for merge."
