# Expansive

Evaluates generalization potential

Layer: Mind · Category: Reasoning

## Mechanism

A [Judge](https://mindscape.pages.dev/bootstrap/Judge.md) of generalization potential: does the mechanism or concept transfer beyond the original domain it was designed in? Applies wherever breadth-of-application is the evaluative question — scientific generality, platform reuse, pattern-library transferability, business model cross-market viability. The essential move is stress-testing the artifact against domains deliberately outside its origin (hostile-domain probe) rather than demonstrating it on familiar cases. Specific rating semantics belong on descendants or on the composing protocol. The signature Judge([Value](https://mindscape.pages.dev/bootstrap/Value.md)) captures that the output is a [Value](https://mindscape.pages.dev/bootstrap/Value.md)-graded breadth score rather than a binary transferable/not-transferable verdict.

## Invariants

- Tested outside its origin domain, not demonstrated within it.
- Names what the candidate already proves in its incumbent domain.
- States the transfer hypothesis being tested.
- Yields a [Value](https://mindscape.pages.dev/bootstrap/Value.md)-graded breadth score, not a binary verdict.

## Failure modes

- Familiar-case demonstration: breadth is argued from examples inside the origin domain.
- Unfalsifiable transfer: no hypothesis is stated, so no result can disconfirm the breadth claim.
