A regime changes when its underlying rules, expectations and distributions of authority shift while enough continuity remains for collective life to continue. RegimeMutation names this intermediate condition between minor adjustment and total replacement. Institutional change rarely occurs through a single rupture; it more often accumulates through revised standards, altered funding priorities, new technologies, changing professional norms and exceptions that gradually become normal practice. Policy studies often capture these transitions through incremental reform, while organizational sociology shows how informal routines can mutate faster than formal structures. The decisive point is that continuity and transformation are not opposites. A system can preserve its name, buildings and legal identity while operating according to substantially different assumptions. Conversely, dramatic symbolic change may leave everyday relations almost untouched. Socioplastics uses RegimeMutation to identify changes at the level where social form is actually reorganized: permissions, categories, responsibilities, access and expected behaviour. This makes mutation empirically traceable. One can ask which actors gained discretion, which procedures became obsolete, which forms of evidence entered decision-making and which populations acquired or lost access. Institutional resilience depends partly on this capacity to mutate without requiring collapse as the precondition for change. A living regime preserves enough structure to remain legible while allowing its internal grammar to evolve in response to conditions it could not previously accommodate.

Repair is most valuable when it changes more than the broken component. RepairFeedback names the moment when information generated by failure returns to the system and alters future design, maintenance or governance. Many institutions repair repeatedly without learning: the same pipe bursts, the same interface confuses users, the same neighbourhood floods, the same administrative bottleneck returns after every temporary intervention. In such cases repair restores function while preserving the mechanism that produced failure. Repair studies reveal a different possibility, treating breakdown as a source of structural knowledge. Maintenance engineering formalizes this through inspection, failure analysis and redesign; infrastructure studies show how repair also exposes labour, dependency and political priority. Socioplastics extends the logic beyond technical systems. A repaired regulation can incorporate the exception that revealed its weakness; a revised curriculum can respond to recurring exclusion; a public space can be altered after patterns of conflict reveal the limits of its original design. Feedback becomes real only when the information travels upward far enough to modify the rule rather than merely the symptom. This requires archives of failure, institutional memory and channels connecting maintenance workers, users, designers and decision-makers. RepairFeedback therefore converts maintenance from repetition into learning. A system capable of receiving its own breakdowns as evidence becomes more adaptive over time, while a system that repeatedly restores appearances without changing causes slowly institutionalizes failure itself.
