 ### Fixes
 
 - Plugins/onboarding: trust optional official plugin and web-search installs selected from the official catalog so npm security scanning treats them like other source-linked official install paths. Thanks @vincentkoc.
-- Plugins/onboarding: default official diagnostics plugin choices to ClawHub while keeping npm fallback metadata, matching the intended storepack-first install path. Thanks @vincentkoc.
 - Microsoft Teams: persist sent-message markers across Gateway restarts so follow-up replies to recent bot messages keep resolving the original conversation instead of dropping out after restart, with marker TTLs preserved on best-effort recovery. (#75585) Thanks @amknight.
 - Matrix: persist pending approval reaction targets across Gateway restarts so room approvers can still approve or deny outstanding prompts after OpenClaw comes back online. (#75586) Thanks @amknight.
 - Channels/onboarding: map third-party official WeCom and Yuanbao catalog entries to their published plugin ids so npm installs pass expected-plugin validation. Thanks @vincentkoc.
