The Changes tab on a simulation’s page is its history. Every change that reaches trainees is a numbered version, newest first, whichever door it came through: the edit wizard, a testing round, or a rollback.
Changes tab listing a rollback (v3), an edit round (v2), a round 1 testing update (v1) and the initial build

What each row records

The initial build is the baseline. Each later row carries an audit line saying who did what and when: Expand a row for what went into it:
  • Inputs on a build or edit: the description you wrote and the files you uploaded, listed by name
  • Build plan: the plan approved for that version
  • Plan and answers and Report on a testing update or rollback: the plan, the questions and answers, and the report Reddy wrote when it shipped
  • What changed and Files changed: the plain-language summary and the simulation files the change touched
An edit round expanded to show the edit description and the uploaded file listed by name
Uploaded materials are listed by name only. They stay with the simulation for Reddy to work from, but they cannot be downloaded or played back from this page.

​
Version numbers

The version marked latest is what trainees play now, and the same number shows on the Testing tab. Numbers only go up: a rollback is a new version that restores an earlier state, not a deletion of history. Roll back this update appears on the newest version when it can be undone; see Rolling Back a Change.
