# surplus (excess)

Output that exceeds the capacity of input windows to consume it.

- Computed level: L19 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: emergence

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

**Through:** The interplay of drifting conditions against bounded capacity windows reveals when potential cannot be absorbed due to fixed size limits.

**Novel properties:**
- unabsorbed flow
- capacity saturation

## Examples
- The 2008 U.S. housing market collapsed after mortgage-backed securities exceeded regulatory absorption capacity. *(economics)*
- The Fukushima nuclear plant produced decay heat after shutdown, exceeding coolant system intake capacity. *(engineering)*
- Amazon's 2020 warehouse automation generated robotic inventory movement faster than human packers could process. *(computing)*
