What
The request that checks whether metrics logging is opted out is now tied to the session's existing credential and shares a one-shot refresh marker, so it cannot kick off its own re-authentication. Failures are classified as 401, 403, timeout, network error, 5xx, other 4xx or unknown. The telemetry shutdown wait is clamped by CLAUDE_CODE_OTEL_SHUTDOWN_TIMEOUT_MS.
