# robust (resilient)

a parameter whose window is wide

- Computed level: L8 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: ontology

## Emergence
**Emerges from:** [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [wide](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wide.spatial)

**Through:** The condition of a parameter defines a range as a window, which can be wide, and remains open despite drift due to the structural permissiveness of windows.opening.

**Novel properties:**
- wide tolerance band
- drift accommodation
- persistent openness

## Examples
- The International Space Station maintains attitude control despite frequent docking maneuvers and atmospheric drag. *(engineering)*
- The human immune system neutralizes thousands of pathogen variants without collapsing into chronic dysfunction. *(biology)*
- The Internet Protocol survived the 1990s traffic surge, scaling from millions to billions of packets daily. *(computing)*
