 /**
- * SQLite durable session-persistence backend (`@deepseek-ai/dsh-session-persistence-sqlite`).
- *
- * A SECOND {@link SessionPersistence} implementation, built to validate that the
- * abstract seam + the shared `runPersistenceContract` suite are genuinely
- * backend-agnostic: the same append-only / contiguous-seq / lazy-materialization
- * / interrupted-turn-close-on-load semantics the JSONL backend expresses over
- * file bytes, expressed here over `node:sqlite` rows. Each `SessionEvent` maps
- * 1:1 onto a row `(session_id, seq, type, time, data, source_event_seqs, surface_op)`.
- *
- * Like the JSONL backend it supplies ONLY the storage primitives (the
- * {@link PersistenceBackend} hooks below — INSERT/DELETE/SELECT inside
- * transactions); all the write-path orchestration lives in the backend-agnostic
- * {@link PersistenceCoordinator} this class composes. The four public
- * {@link SessionPersistence} methods delegate to the coordinator.
- *
+ * SQLite durable session-persistence backend. It maps each session header and
+ * event to rows, and delegates write-path orchestration to
+ * {@link PersistenceCoordinator}.
