Struct MessagePage 

pub struct MessagePage {
    pub messages: Vec<Message>,
    pub next_cursor: Option<String>,
    pub total: u32,
}

One page of the record, newest first.

Fields

messages: Vec<Message>

The page’s messages, messages[0] being the most recently appended one. Every message carries the id and inserted-by its record line holds, and a message whose role is "tool" carries the envelope this interface’s doc describes.

next_cursor: Option<String>

Cursor for the next (older) page, or none when this page reached the oldest message in the record.

total: u32

Parseable messages in the whole record at the moment this page was served, not in this page. A record line that is not a message is skipped and not counted.

A snapshot, not a loop invariant: the runtime appends while a hook pages, so total can grow from one page to the next and the page lengths of a completed walk can sum to less than the final total. Every page is a consistent snapshot anchored at the oldest message, so nothing repeats and nothing is skipped; a loop is sized by next-cursor: none, which is the only correct termination condition.
