## Why it may appear legitimately

Variation selectors intentionally choose glyph presentation, including text and emoji forms.

- Unicode glyph variants and metadata encodings

## Launch behavior

Registry status: report-only. Watermark Slayer reports this observation and does not propose a cleanup edit.

## What a change could affect

Removing selectors can change visible glyph presentation or separate a meaningful selector sequence.

- Selectors can be meaningful to visible glyph rendering.

## Claim boundary

Finding this artifact says only that the specified code point or framing was observed. It is not an authorship verdict, detector score, or evidence that text came from a particular system.
