@@ -35,6 +35,7 @@ Docs: https://docs.openclaw.ai
 - Plugins/ClawHub: sanitize temporary archive filenames for scoped package names and slash-containing skill slugs so `openclaw plugins install @scope/name` no longer fails with `ENOENT` during archive download. (#56452) Thanks @soimy.
 - Telegram/polling: keep the watchdog from aborting long-running reply delivery by treating recent non-polling API activity as bounded liveness instead of a hard stall. (#56343) Thanks @openperf.
 - Memory/FTS: keep provider-less keyword hits visible at the default memory-search threshold, so FTS-only recall works without requiring `--min-score 0`. (#56473) Thanks @opriz.
+- Memory/LanceDB: resolve runtime dependency manifest lookup from the bundled `extensions/memory-lancedb` path (including flattened dist chunks) so startup no longer fails with a missing `@lancedb/lancedb` dependency error. (#56623) Thanks @LUKSOAgent.
