adk_otlp_json (erlang_adk v0.7.0)
View SourceStrict, dependency-light OTLP/HTTP JSON projection.
Completed v2 operation spans are mapped to ExportTraceServiceRequest and metadata-only v1 envelopes are mapped to ExportLogsServiceRequest. The mapper follows the OTLP JSON deviations from proto3 JSON: trace/span IDs remain hexadecimal, enum values are numbers, and every int64 value is a decimal string. It never maps prompt/response/media/tool payload content.
