What

Compaction means shortening a stored conversation history so it takes less space. New internal helpers record the times when an agent's classifier history is compacted. Both the number of records and the size of the table are capped, and a cached token count (prevCacheReadTokens) is reset. Another helper deletes an agent's compaction records, classifier lines and previous state.

Why

This is internal housekeeping so the records do not keep growing. The finding does not show a visible change for users.
