Conversation
Long-running agent sessions lose their Rewind cache when the process restarts. This adds save() and load() methods to persist RewindStore entries to a JSON file and restore them later. - save() writes only non-expired entries with remaining TTL - load() merges entries into the live cache without overwriting - Entries that would be expired on load are skipped - max_entries limit is enforced after loading

Summary
Adds
save()andload()methods toRewindStorefor persisting cache to disk.Problem
In long-running agent sessions, a process restart wipes the in-memory RewindStore. Any
[[REWIND:sha256:...]]markers in the conversation become unresolvable, breaking the reversible compression contract.Solution
store.save("/tmp/rewind_cache.json")— writes all non-expired entries with their remaining TTLstore.load("/tmp/rewind_cache.json")— merges entries back into the live cachemax_entrieslimit enforced after loadingUsage
