What
The SDK bridge, which relays control requests between a client and Claude Code, now measures and logs how long each control_request took to process. The new telemetry event also records whether the request was "detached" and, when a deadline was set on the request, what that deadline was and whether it was exceeded.
Why
This gives better visibility into bridge performance and helps diagnose slow or timed-out control requests when building on the SDK.
