pub fn from_jsonl(text: &str) -> Result<Vec<ModelChangeRecord>, Error>Expand description
Parse a JSONL model-change log back into records — the exact inverse of
to_jsonl. Blank lines are skipped; a malformed line is a hard error
(like crate::usage_log::from_jsonl — this is accounting/provenance
data, corruption should be visible, not silently dropped).
