+> **Compatibility tip:** When a comment anchors itself to a video definition address, emit both the uppercase root pointer and a legacy `['e', <root event id>]` tag. This mirrors the [NIP-22 addressable events example](./nips/22.md#addressable-events) so clients that only understand `#e` tags can still follow the thread.
