Comparison explanationExecution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:
Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

The actual changes in this file are storing this new bool _openTelemetrySemanticsEnabled and using it to stop adding Datadog-specific span attributes. The rest of the changes are due to moving methods around to satisfy StyleCops ordering after changing methods from private to internal

…LED.
When enabled, the tracer will not attempt to remap known OpenTelemetry attributes when handling OTEL spans and instead preserve them. A unit test has been added to assert that `Activity.SetTag("http.response.status_code", 200)` maintains both the original attribute key AND value (an integer)
…ce serializers from adding the following Datadog-specific attributes: - service.name - operation.name - resource.name - span.type

…o align the DD OTLP spans with the OTel OTLP spans. Removes the following span attributes: - otel.library.name - otel.library.version - otel.status_code - otel.trace_id

LGTM Thanks! Added one comment and aside from it:
Note these OTel-semantics items don't currently fail CI because the SubmitsOtlpTraces_DD_OtelSemantics snapshot was baselined from the current output, so it passes despite them (no status field on any span, and runtime-id / otel.status_description showing up as span attributes). Could we add a few targeted tests that would fail on the cases called out in the inline threads — and maybe the ones without coverage today (error.type/error.stack set directly by integrations like GraphQL/Quartz, _dd.origin, per-span service.name, and default-MessagePack export still writing the error tags)?
That said, if you feel the existing tests already cover what we care about for this initial effort, I'm totally fine with merging as is.

thanks!! minor NIT and left a little comment on the OtlpHelpers about otel.status_code I'm unsure about
- Update inline data for unit testts where we assert attribute keys that should not be emitted from OtlpMapper - Update 'otel.status_code' handling for already standardized or custom values to keep the previous behavior

Summary of changes
Adds an opt-in OpenTelemetry semantics mode for OTLP trace export.
This feature is enabled by setting
DD_TRACE_OTEL_SEMANTICS_ENABLED=true, which was previously introduced in #8826. When enabled, spans produced from OpenTelemetry instrumentation are serialized closer to native OpenTelemetry SDK output by preserving OTel attribute keys and value types, and by suppressing Datadog-specific attributes from OTLP trace payloads.Reason for change
We should support scenarios where customers use the Datadog SDK but want their emitted OTLP data to look as close as possible to data produced by the OpenTelemetry SDK. This helps users route Datadog-instrumented applications through OTel collectors or other OTLP consumers without the payload including Datadog-specific span attributes that are not part of the OpenTelemetry semantic conventions.
Implementation details
Refactors
SetExceptionTagsflow intoSetException(exception, markAsError)so callers can add exception metadata without forcing the span error flag.Instrumentation changes:
OtlpHelpersso, when enabled, the Activity-to-span conversion does not do any attribute remapping or special handling for Datadog-specific attributes, preserving the original attribute keys and values on the OTLP span.otel.trace_id,otel.library.name,otel.library.version, andotel.status_codeto match newer OTel SDK behaviors.Span changes:
exceptionspan event withexception.type,exception.message, andexception.stacktraceattributes instead of Datadog error tags.OTLP Exporter changes
OtlpMapper.EmitAttributesFromSpanso OTel semantics mode suppresses Datadog-specific or compatibility-only span attributes, includingservice.name,operation.name,resource.name,span.type,component,span.kind,service.version,service.instance.id,otel.status_code, andhttp-client-handler-type.Test changes
