# invasive (system)

a system whose window is wider than the local walls were built to exclude

- Computed level: L17 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window ontology  ·  Arena: systems theory

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

**Through:** The organized system maintains function across a wide parameter window that surpasses the intended exclusion range of local structural boundaries.

**Novel properties:**
- unintended permeability
- boundary override
- persistent external integration

## Examples
- The Burj Khalifa's HVAC system cools spaces beyond the building’s original insulation specifications during Dubai summer peaks. *(engineering)*
- Zebra mussels spread through the Great Lakes via ballast water discharge, colonizing pipe systems not screened for such larvae. *(ecology)*
- Windows 10 telemetry updates activated features in enterprise Group Policy environments where admin controls had blocked prior data sharing. *(computing)*
