# obsolete (inactive)

a system still inside its window, in an environment where nothing sits inside its input window

- Computed level: L15 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window ontology  ·  Arena: emergent systems

## 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), [maintenance](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-maintenance.upkeep), [environment](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-environment.surroundings), [inside](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-inside.spatial), [nothing](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-nothing.absence), [still](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-still.quiet), [system](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-system.organized)

**Through:** The absence of input through an open window in the environment causes a persistent system to lose function even though its parameters remain within viable limits.

**Novel properties:**
- loss of function without parameter failure
- persistent inactivity from environmental absence
- structural integrity without operational continuity

## Examples
- The Mir space station drifted in low Earth orbit from 1991 until 2001, receiving no commands after Soviet ground control collapsed. *(engineering)*
- After the 2008 financial crisis, abandoned subdivisions like Osborne, California, remained zoned for development but saw no new construction. *(economics)*
- The Arecibo Observatory's radar transmitter sat inactive from 2017 until its 2020 collapse, though the dish remained structurally intact. *(physics)*
