Keep authored keys protected

  • Existing artist keys inside the requested span are not silently replaced.
  • Adjust rebuilds a managed result from the current endpoint poses instead of stale captured values.
  • Expression and unsupported pre/post tracks are rejected instead of baked without notice.
  • A complete application is one Blockbench Undo transaction.
