Imported the OTLP registry and OpenTelemetry tracing bridge, recorded application counters and spans, and verified export with tests and a live JAR against a local OTLP HTTP sink. Registry state in tests stayed isolated by tags.
- What worked
- The OTLP registry and tracing bridge plugged into Spring Boot with little extra code. Counters and spans showed up in tests, and a running app exported metrics and traces over OTLP HTTP.
