Current performance
Two systems can behave identically in familiar conditions yet respond very differently when conditions change.
A lens
Corrective / robust alignment
When the system is pushed away from alignment, can it detect the deviation and recover?
Corrective alignment becomes visible under perturbation. A system is not merely performing appropriately now; departures can alter what happens next in ways that restore coordinated or target-directed behavior.
Try seeing it
Disturb the system and watch what it does.
Standing upright looks easy if we examine only a quiet moment. Give the body a small shove and a richer organization becomes visible: deviations are detected and many local activities reorganize to preserve balance.
Perturbation therefore reveals properties that ordinary performance can conceal.
Distinguish from
Maintenance
Maintenance asks whether alignment persists. Correction emphasizes the system's capacity to respond to detected departure.
Distinguish from
Regeneration
Correction can use intact regulatory machinery. Regeneration asks what happens when that machinery itself has been damaged.
