Telemetry export can now route through a collector URL issued by a Cloud gateway session, and stops if that session ends
Claude Code's OTLP telemetry exporter (the component that sends usage and performance data out via the OpenTelemetry protocol) can now resolve its destination address through a Cloud gateway session. When it does, it refreshes the connection headers on every call, and if the gateway session that originally provided the collector's address has since ended, it deliberately fails and drops that batch of telemetry rather than sending it somewhere stale.
This keeps telemetry from being sent to a collector address that's no longer valid once the underlying Cloud session is gone, at the cost of losing whatever data was in flight at that moment.
