pub fn invert_one_messages(
reduced: &[ChatMessage],
log: &ReductionLog,
id: &str,
sidecar_messages: &[ChatMessage],
) -> Result<(Vec<ChatMessage>, ReductionLog)>Expand description
Rehydrate a single reduction by id (C4 /expand <id>; also used for
per-range TurnsCleared expansion). Returns the updated view and a log
with that record removed (an expanded reduction is no longer “applied”).
Other placeholders in reduced are untouched — their bytes remain
identical.
