# margin (spatial)

The distance from current parameters to the nearest wall.

- Computed level: L11 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: parameter stability

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

**Through:** The margin emerges as the buffer between a current parameter and the nearest wall of its window, indicating how much drift is possible before the parameter exits its range.

**Novel properties:**
- proximity to boundary
- spatial buffer
- range tolerance

## Examples
- The International Space Station maintains a 50-kilometer buffer from orbital debris tracked by NORAD. *(engineering)*
- The Hoover Dam's spillway design leaves a 23-meter margin between normal water level and the top of the structure. *(infrastructure)*
- Neurons in the human cortex fire within 70 milliseconds of stimulus onset, operating just under the 100-millisecond cognitive threshold. *(neuroscience)*
