Patch
A new direction.
Keep the useful work.
An earlier decision changes. Patch creates a new plan revision, identifies affected steps and keeps the useful work in view.
Interactive Simulation
What Is Happening Here?
The example is deliberately small. These are the parts to understand before bringing your own task.
Trace The Impact
See recorded and inferred dependencies. A later step with uncertain independence needs a recheck, not blind preservation.
Respect File Identity
The platform compares retained file versions and current preconditions. A conflicting version can hold repair for review.
Keep The History
Inspect what was revised, redone, preserved or left unresolved. Repeating an external effect can need fresh approval.
Where It Stops
Impact analysis can be incomplete. Patch is not a universal undo button and cannot reverse arbitrary external actions. Appropriate tests and human review remain necessary.
