# no free openings (no-openings)

Every parameter's range is constrained by the narrowing of a range below it, so that a new range cannot open without cost to an existing one.

- Computed level: L18 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: system

## 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), [narrow](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-narrow.spatial), [below](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-below.spatial), [cost](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-cost.economic), [new](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-new.recent), [open](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-open.spatial), [range](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-range.spatial)

**Through:** When one parameter narrows a range, it shifts the boundary for another above it.

**Novel properties:**
- interdependent range boundaries
- costed range emergence
- hierarchical parameter constraints

## Examples
- In New York City, adding a new subway line requires shutting down existing lines, disrupting service for thousands daily. [transit] *(engineering)*
- The 2020 California power shutoffs cut electricity to 172,000 homes to prevent wildfires from overloaded grid lines. [energy] *(institutions)*
- Amazon’s warehouse automation reduced open positions by 30% while increasing output, eliminating roles without expanding labor capacity. [logistics] *(economics)*
