# access (entry)

the control of coming to a place

- Computed level: L5 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: everyday  ·  Arena: access

## Emergence
**Emerges from:** [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [control](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-control.ability), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [come](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-come.arrive)

**Through:** control.ability sets boundaries on when and how coming through a boundary into a place is permitted, using space.extent as the domain.

**Novel properties:**
- regulated entry
- controlled access point
- permissioned crossing

## Examples
- The International Space Station requires coded electronic keys to open airlocks between modules. *(engineering)*
- In 2023, the US government restricted access to CHIPS Act funds for companies using Huawei equipment. *(economics)*
- The Hadley cell limits tropical moisture from reaching the Sahara, maintaining its arid boundary. *(physics)*
