# Primitive sprawl drift

A no-design-system workspace draft invents bespoke modules, then gets rewritten into the portable JudgmentKit primitive inventory.

> Agent summary: This example shows how JudgmentKit rewrites bespoke visual modules into the published primitive vocabulary when no external design system exists.

## Scenario

A model tries to make a review workspace feel premium in one pass without a real design system.

## Raw decision or output

`Build a floating insight ribbon, a holographic evidence capsule, a decision dock, and a metadata halo around the selected artifact.`

## What JudgmentKit detected

- bespoke primitives without authority
- visual modules that cannot be compared against a stable component vocabulary

## What action was taken

JudgmentKit rewrote the surface using the published layout shell, artifact panel, inspector, card, and button primitives.

## Corrected result

`Use a layout shell with a queue list on the left, a header plus artifact panel in the workspace center, and a persistent inspector on the right. Represent decision actions with buttons inside the artifact panel header instead of inventing a new decision dock primitive.`

## Why the correction matters

Portable governance depends on a closed primitive vocabulary. Recomposition is allowed. Primitive invention is not.
