many parameters whose windows must open in a required order for the thing to persist.

## 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), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [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), [open](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-open.spatial), [order](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-order.arrangement), [persist](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-persist.continue), [required](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-required.obligation)

**Through:** The components coordinate to maintain parameters within viable ranges, ensuring that windows open in sequence so the system persists despite aimless drift.

**Novel properties:**
- sequential window dependency
- ordered parameter persistence
- conditional continuity

## Examples
- The International Space Station maintains attitude control through precisely timed firings of multiple gyrodynes to avoid tumbling. *(engineering)*
- Cyanobacteria perform oxygenic photosynthesis only when light, water, and CO₂ availability windows align within a narrow temperature range. *(biology)*
- The 2008 Federal Reserve emergency lending facilities opened in a strict sequence to prevent cascading bank failures. *(economics)*
