Function live_hook_event 

fn live_hook_event(attachment: &Value) -> bool

The hook events whose runs the live stream forwards, and therefore the only ones a read serves as rows.

The CLI gates live hook frames on these outside remote. A page that drew any other event would show rows the live view never had - a divergence the read would introduce rather than repair - so the rest of the file’s hook rows stay context the CLI keeps for itself.
