 ### Fixes
 
+- Config/messages: coerce boolean `messages.visibleReplies` and `messages.groupChat.visibleReplies` values to the documented enum modes so an intuitive toggle no longer invalidates config and drops channel startup. Fixes #75390. Thanks @scottgl9.
 - Feishu: accept and honor `channels.feishu.blockStreaming` at the top level and per account, while keeping the legacy default off so Feishu cards no longer reject documented config or silently drop block replies. Fixes #75555. Thanks @vincentkoc.
 - Google Chat: normalize custom Google auth transport headers before google-auth/gaxios interceptors run, restoring webhook token verification when certificate retrieval expects Fetch `Headers`. Fixes #76742. Thanks @donbowman.
 - Doctor/plugins: reset stale `plugins.slots.memory` and `plugins.slots.contextEngine` references during `doctor --fix`, so cleanup of missing plugin config does not leave unrecoverable slot owners behind. Fixes #76550 and #76551. Thanks @vincentkoc.
