# stranger (unmodeled)

An entity for which no model exists, so full verification cost applies. An introduction lends a cache entry.

## Emergence
**Emerges from:** [model](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-model.representation), [cost](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-cost.economic), [entities](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-entities.object), [application](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-application.use), [maintenance](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-maintenance.upkeep), [applying](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-applying.action), [full](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-full.state)

**Through:** The components together enable recognizing when an unknown entity lacks a predictive model, requiring full verification until an initial representation is established and cached.

**Novel properties:**
- unmodeled status triggers full verification
- cacheable initial representation
- verification cost in absence of model

## Examples
- The 2023 James Webb Space Telescope calibration required full instrument re-verification after unexpected radiation exposure. *(astronomy)*
- A lost bank customer ID at Chase in 2022 triggered full identity checks, costing $420 in labor and delays. *(finance)*
- When the unknown object ʻOumuamua passed through the solar system in 2017, every observation required new modeling effort. *(astrophysics)*
