# Message Thread Reveal editing contract

## Surface ownership

This template depicts a phone messaging interface. The supplied website is content shared inside the thread and on the closing card; it does not own the messaging application chrome.

## Editable slots

Only defaults declared in `data-composition-variables` are editable:

- `contactName`, `cardTitle`, and `cardDomain`
- `ecProof` and `ecCta`

Keep replacement copy within 20% of the original length.

## Protected

Preserve messaging chrome, bubbles, receipts, emoji, fixed conversation beats, link-card image, logo asset, palette, typography, geometry, scene structure, duration, timing, easing, and reveal behavior.
