 - Plugins/update: treat official externalized bundled npm migrations and ClawHub-to-npm fallbacks as trusted source-linked installs, so prerelease-only official plugin packages can migrate from bundled builds without being rejected as unsafe prerelease resolutions. Thanks @vincentkoc.
 - Plugins/update: clean stale bundled load paths for already-externalized pinned npm and ClawHub plugin installs, so release-channel sync does not leave removed bundled paths ahead of the installed external package. Thanks @vincentkoc.
 - Plugins/CLI: include package dependency install state in `openclaw plugins list --json` so scripts can spot missing plugin dependencies without runtime-loading plugins.
+- Google Meet: preserve `realtime.introMessage: ""` so realtime Chrome joins can stay silent instead of restoring the default spoken intro. Thanks @vincentkoc.
 - Discord/status: add degraded Discord transport and gateway event-loop starvation signals to `openclaw channels status`, `openclaw status --deep`, and fetch-timeout logs so intermittent socket resets do not look like a healthy running channel. (#76327) Thanks @joshavant.
 - Providers/OpenRouter: add opt-in response caching params that send OpenRouter's `X-OpenRouter-Cache`, `X-OpenRouter-Cache-TTL`, and cache-clear headers only on verified OpenRouter routes. Thanks @vincentkoc.
 - Providers/OpenRouter: expand app-attribution categories so OpenClaw advertises coding, programming, writing, chat, and personal-agent usage on verified OpenRouter routes. Thanks @vincentkoc.
