Reading a change
- Challenge correction
- A source fact or starting condition changed. The challenge revision identifies the state used by a saved attempt.
- Rules or model update
- The simulation's legal actions, timing or possible outcomes changed. Records across those versions may not be comparable.
- Interface fix
- The way an existing state is displayed or controlled changed. Replay uses the saved events and versioned action sequence.
For an incorrect challenge state, include its identifier and revision in a report. Read Methodology for the difference between historical facts and simulated outcomes.
