# overdue (temporal)

a parameter whose window has remained unoccupied for a time longer than drift alone would account for

- Computed level: L12 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: general

## 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), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [unoccupied](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-unoccupied.spatial), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [long](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-long.size), [account](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-account.financial), [alone](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-alone.state)

**Through:** The components together identify when a parameter's allowable range has stayed vacant beyond what unguided change would typically cause.

**Novel properties:**
- excess duration of vacancy
- deviation beyond random drift
- temporal expectation failure

## Examples
- The 2020 eruption of Taal Volcano in the Philippines followed 43 years of seismic quiet, far exceeding the average 15-year cycle. *(geology)*
- The Hubble Space Telescope's 1990 deployment revealed a flawed mirror, delaying its scientific mission by three years until corrective servicing. *(engineering)*
- Argentina's 2001 default occurred after 17 years of recurring debt crises, long past the typical recovery window for emerging markets. *(economics)*
