Function select_closed 

pub fn select_closed(
    project_state: &Path,
    unit: &str,
    closed: &[(String, Vec<String>)],
) -> Selection

Selects, from every set stored for unit (whatever its key: a task’s today, a sealed set’s once the store holds them — one protocol), those whose manifest digest a closed task names. closed is (task, digests its evidence names). Each selected set is checked against its digest first; a tampered one is never published.
