# Robustness

Resistance to failure under stress

Layer: Society · Category: Protocols

## Mechanism

The capacity of a system or argument to maintain its validity and function under stress, perturbation, or attack. Unlike Antifragility (which gains from disorder), Robustness merely resists it. It acts as a stability criterion for all checks and structures.

## Invariants

- Names the stress envelope it holds under.
- Names the validity criterion the [System](https://mindscape.world/scapes/bootstrap/System.md) preserves within that envelope.
- Function is preserved under stress, not improved by it.

## Failure modes

- Rigidity: [System](https://mindscape.world/scapes/bootstrap/System.md) becomes too stiff to adapt
- False Robustness: Valid only under known stressors, fragile to black swans
