What

A managed remote session that has an SDK URL now loads and starts a vitals emitter on demand, logging a warning if that load fails. A CLAUDE_CODE_DISABLE_VITALS_EMITTER variable exists to switch it off.

Details
  • Requires a remote session id, an SDK URL, and a further runtime check before it starts.
