A self model reporting a wall as near and moving nearer, so that it narrows its own reach before any crossing.

## Emergence
**Emerges from:** [self-model](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-self-model.reflexive), [report](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-report.information), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [near](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-near.spatial), [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement), [narrow](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-narrow.spatial), [reach](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-reach.action), [cross](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-cross.pass), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension)

**Through:** The report arrives before the wall does: the self model reads a closing distance and pulls its own reach inward, which protects when the wall is real and costs reach when it is not.

**Novel properties:**
- a wall acted on before it arrives
- reach narrowed by a reading, not a wall
