1// Package telemetry is the relay's process-local observability boundary.2//3// Telemetry owns an isolated Prometheus registry, OpenTelemetry tracer4// provider, structured logger and authenticated diagnostics handlers. Metrics5// use bounded operation and outcome labels. New configures sampling and an6// optional OTLP HTTP exporter; Close flushes and shuts down the tracer7// provider. HTTP exposes metrics and, when configured, token-protected8// diagnostics without registering process-wide handlers.9package telemetry
