## Why Reconstructing the latest model-visible context does not require replaying an entire paginated rollout when a usable compaction checkpoint and the associated completed-turn metadata are available. ## What changed - Add `ThreadStore::load_latest_model_context` and `StoredModelContext` for loading replay-ready model context independently of full thread history. - Reverse-scan plain paginated JSONL rollouts until the newest safe bounded suffix is found, while preserving canonical session metadata and chronological replay order. - Fall back to complete history for legacy or compressed rollouts and whenever compaction or rollback records make a bounded cutoff unsafe. ## Testing - Cover checkpoint selection, turn-metadata boundaries, agent messages, contextual user fragments, and full-history fallbacks.
