Function export_jsonl 

pub fn export_jsonl<W: Write>(
    store_dir: &Path,
    out: &mut W,
    include_internal: bool,
) -> Result<u64, MemoryError>

Write every live fact of the store at store_dir to out, one JSON object per line: {"id", "id_str", "content", "metadata"}. Returns how many lines were written.

Visibility follows list_memories’ policy: internal graph scaffolding is skipped and reserved keys are stripped (the auto-stamped date survives), unless include_internal — a backup wants everything verbatim.

No embedder is built and no provenance check runs: this is the one read path that must work on a store whose configured embedder no longer matches — your data stays yours even mid-misconfiguration.

Errors

Returns MemoryError when the store cannot be opened or walked, and I/O errors from out wrapped as MemoryError::InvalidFilter-free storage errors.
