- Cache.sq / ChatDb: lanes, channels and last_lane persisted as JSON
snapshots; sanitize on restore (Pending->Failed, streaming->false);
ephemeral items (tool, system) skipped
- Platform drivers via expect/actual: AndroidSqliteDriver (app db dir)
/ JdbcSqliteDriver (~/.iris/iris_cache.db)
- IrisController: restore before connect, debounced (750ms) snapshot
persistence, synchronous flush on dispose, clearAll on forget
- History robustness: historyLoaded marked only when the response is
processed (lost request/response retried on reconnect); events
collector wrapped in try/catch; onHelloAck fast path so the history
request fires on the WS thread instead of the starved state
collector; frame-decode and history-load logging
- Protocol: HistoryMessage.media nullable (defensive vs older
gateways that sent "media": null)
- Tests: ChatDbTest (jvmTest, JDBC in-memory), ChatStoreCacheTest,
HistoryPayloadTest, HistoryWireTest (real captured 92KB response)
- docs/10: §10.7 implemented schema, new §10.9 cache behavior
