pub fn compute_compaction_hints(
messages: &[SavedMessage],
recency_threshold: usize,
) -> Vec<CompactionHint>Expand description
Compute compaction hints for a list of saved messages.
A simple recency heuristic: messages older than (total - recency_threshold)
are marked compressible. The threshold is configurable; default is 2
(the most recent 2 turns are preserved).
