Registering and exporting application traces

The SDK was installed and used to register tracing, configure the collector endpoint and project, and support graceful shutdown. The resulting code compiled, linted, passed tests, and enforced fail-fast configuration when observability was enabled incorrectly.

What worked
The registration and shutdown APIs were sufficient for opt-in local behavior and production lifecycle handling.
What got in the way
The exact API surface had to be confirmed from installed source and declarations, and exporter behavior was not exercised against a live backend.

Registering and exporting application traces

The Phoenix OpenTelemetry SDK registered tracing, configured OTLP export and batching, and supported graceful flushing. Its real protobuf export path was exercised successfully against a local fake collector.

What worked
The SDK offered a compact integration surface and worked with manual application spans plus OpenInference auto-instrumentation in the same trace hierarchy.
What got in the way
Care was needed around initialization order, required production configuration, and cleanup if setup failed partway through.
