 ### Fixes
 
 - Slack/messages: serialize write-client requests and whole outbound sends per target so rapid multi-message Slack replies preserve send order. Fixes #69101. (#69105) Thanks @nightq and @ztexydt-cqh.
+- Slack/messages: keep Slack bot tokens out of internal message-ordering and DM cache keys.
 - Slack/exec approvals: resolve native approval button clicks over the Gateway instead of delivering `/approve ...` as plain agent text, preserving retry buttons if Gateway resolution fails. Fixes #71023. (#71025) Thanks @marusan03.
 - Browser/tool: expose browser doctor diagnostics to agents and extend `openclaw doctor` browser readiness notes for managed Chromium launch prerequisites. (#62948, #62936) Thanks @seanc-dev.
 - Slack/files: return non-image `download-file` results as local file paths instead of image payloads, and include Slack file IDs in inbound file placeholders so agents can call `download-file`. Fixes #71212. Thanks @teamrazo.
