zachlandesandGitHub 02c27d6353 chore: remove private publication markers (#2)
* Removed the stale publication-status comment without changing the
  frozen analysis plan
* Kept the original checksum verifiable after removing that comment
* Repackaged local command paths and removed operator attribution to keep
  the working environment out of the public files
* Rebuilt site references from their sources without changing any prompt,
  answer or measurement
