+Every time a cron-triggered workflow is run it will _start_ with the final
+output of the last successful run. This allows users to build workflows that

Even though steps 2 and 3 modify the state further, only the **first step's output** gets saved for the next cron run. On Tuesday at 9 AM, the cron job starts again with `{ lastProcessedId: 1000 }` from Monday's first step, so it knows to fetch records starting from ID 1001.

 - **Empty input**: `{}` - starts fresh without previous state.
 - **Custom input**: Your own data to test specific scenarios.
 - **Default input**: Uses the same input as the scheduled runs.
