Function packset_write_as 

pub fn packset_write_as(
    label: &str,
    text: &str,
    persona: Option<&str>,
) -> Result<Value>

packset_write as a persona: the claim carries the persona’s entity, so what a persona learned comes back to it first in its next brief and stays in the seat’s one pack. A persona accumulates its own lessons the way a reviewer does; the seat still reads them all.
