 - Google Meet: add `chrome.audioBufferBytes` for generated command-pair SoX audio commands and lower the default buffer from SoX's 8192 bytes to 4096 bytes to reduce Chrome talk-back latency.
 - Google Meet: split realtime provider config into agent-mode transcription and bidi-mode voice providers, and migrate legacy Gemini Live bidi configs with `doctor --fix`, so Gemini Live can back direct bidi fallback without breaking the default OpenClaw agent talk-back path.
 - Google Meet: expose `voiceCall.postDtmfSpeechDelayMs` in the plugin manifest schema and setup hints, so manifest-based config editing accepts the runtime-supported Twilio delay key. Thanks @vincentkoc.
+- Google Meet: keep explicit non-Google `realtime.provider` values as the transcription provider compatibility fallback when `realtime.transcriptionProvider` is unset. Thanks @vincentkoc.
 - Telegram: render shared interactive reply buttons in reply delivery so plugin approval messages show inline keyboards. (#76238) Thanks @keshavbotagent.
 - Agents/cli-runner: drop a saved `claude-cli` resume sessionId at preparation time when its on-disk transcript no longer exists in `~/.claude/projects/`, so a stale binding from a half-installed `update.run` cannot trap follow-up runs (auto-reply / Telegram direct) in a `claude --resume` timeout loop; the run starts fresh and the new sessionId is written back through the existing post-run flow. (#77030; refs #77011) Thanks @openperf.
 - Release validation: install the cross-OS TypeScript harness through Windows-safe Node/npm shims so native Windows package checks reach the OpenClaw smoke suites instead of exiting before artifact capture. Thanks @vincentkoc.
