 ### Changes

 - WhatsApp/outbound: fall back to the first `mediaUrls` entry when `mediaUrl` is empty so gateway media sends stop silently dropping attachments that already have a resolved media list. (#64394) Thanks @eric-fr4 and @vincentkoc.
 - Doctor/Discord: stop `openclaw doctor --fix` from rewriting legacy Discord preview-streaming config into the nested modern shape, so downgrades can still recover without hand-editing `channels.discord.streaming`. (#65035) Thanks @vincentkoc.
 - Gateway/auth: blank the shipped example gateway credential in `.env.example` and fail startup when a copied placeholder token or password is still configured, so operators cannot accidentally launch with a publicly known secret. (#64586) Thanks @navarrotech and @vincentkoc.
+
 - Memory/active-memory+dreaming: keep active-memory recall runs on the strongest resolved channel, consume managed dreaming heartbeat events exactly once, stop dreaming from re-ingesting its own narrative transcripts, and add explicit repair/dedupe recovery flows in CLI, doctor, and the Dreams UI.
 - Agents/queueing: carry orphaned active-turn user text into the next prompt before repairing transcript ordering, so follow-up messages that arrive mid-run are no longer silently dropped. (#65388) Thanks @adminfedres and @vincentkoc.
 - Gateway/keepalive: stop marking WebSocket tick broadcasts as droppable so slow or backpressured clients do not self-disconnect with `tick timeout` while long-running work is still alive. (#65256) Thanks @100yenadmin and @vincentkoc.
