pub fn export_session_spliced(
sidecar: &str,
format: SessionFormat,
session_id: Option<&str>,
) -> Result<String>Expand description
Export a (possibly reduced) live session in format, replaying the
imported prefix verbatim when format is the session’s own origin
(Session::to_jsonl_spliced, SPEC.md A12).
Mirrors export_session exactly, but through the splice path: always
reconstructs from sidecar (the reduced view / ReductionLog are not
inputs), and applies the identical grammar-aware leak guard.
