# Editorial proofreading marks

**#9** · **Domain:** Publishing · **Category:** quality-control · **Difficulty:** 🟢 Low

## Core principle

Mark specific errors without destroying the original.

## AI problem addressed

Review is accept-all or total rewrite — no middle ground.

## Implementation

Tags: `[QUERY]` verify | `[DELETE]` remove | `[STET]` keep | `[TRANSPOSE]` move | `[INSERT]` add
Apply marks; accept/reject individually before delivery.

## Boundaries

- Prototype as prompt scaffold (🟢) before full pipeline middleware (🟡/🔴)
- Category router: **`ai-transfer-quality-control`**
- Catalog: **`ai-transfer-ecosystem-primer`**
