Record the useful changes
Scheduling saves automatically capture meaningful observations: relevant inputs, productive allocations, dates and target/deadline risk. Repeating an identical calculation does not create another record. Monday metadata refreshes and page views do not invent schedule movement.
Use Check today's live forecast after a new planning day or calendar changes maintained outside the app. History begins with recorded observations; it does not reconstruct earlier unrecorded plans.
Follow the explanation
Project history shows a small trend and exact textual records. Expand Contributing changes to see relevant actions, resource gates and prerequisite consequences. Why this date now explains the current plan; the history explains the change around it.
Older records remain available through history navigation. The chosen baseline, original and latest records are separate from the page being inspected.
Preview and Discard never add live history. Apply commits meaningful observations with the actual saved changes. See What If, baseline and What moved.
