Function get_memory_texts_batch 

pub fn get_memory_texts_batch(
    conn: &Connection,
    namespace: Option<&str>,
    after_id: Option<&str>,
    limit: usize,
) -> Result<Vec<(String, String, String)>>

#1598 — keyset-paginated scan over ALL live memories (embedded or not), optionally namespace-filtered, for the ai-memory reembed full-corpus sweep. Same cursor semantics as get_unembedded_ids_batch_after: at most limit (id, title, content) triples with id strictly after after_id, in id order. Four distinct prepared shapes (namespace × cursor) keep the scan sargable (v55/v56 discipline).
