Function fetch_record

    method: &str,

    body: &str,
    headers: &[(String, String)],
    timeout_ms: i64,
    aborted: bool,

One request of a page’s own request table as the fetches axis spells it — every tier’s snapshot renders its table through this, so two tiers that asked for the same request read the same.
