buildLogObject now stamps the active OTel span's real W3C trace_id/span_id onto every record (via @opentelemetry/api trace.getActiveSpan), replacing the fabricated uuid traceId; falls back to the prior uuid correlation id when no span is active. Each record is also emitted through the standard @opentelemetry/api-logs facade so it becomes an OTLP log record (correlated to the active span) when an observability LoggerProvider is registered — a cheap no-op otherwise, stdout output unchanged. Depends only on the @opentelemetry/api + api-logs facades (no SDK, no circular dep on @smooai/observability). Adds a real-SDK round-trip spec proving a log inside a span carries that span's ids in both the stdout JSON and the bridged OTLP record. th-de3805.

Problem
Loggerfabricated a random uuidtraceIdfor every record (CONTEXT/setCorrelationId). Log lines could never be joined to the OTel spans they occurred inside — the id was made up, not the real trace context.Solution (th-de3805)
buildLogObjectnow stamps the active OTel span's real W3CtraceId+spanId(via@opentelemetry/apitrace.getActiveSpan()?.spanContext()) onto every record. Falls back to the prior uuid correlation id only when no span is active. Stamped after the config/redact transforms so it always survives. Added aspanIdcontext key.@opentelemetry/api-logsglobal logger, so a log line becomes an OTLP log record (correlated to the active span, which the logs SDK reads from context) whenever an observabilityLoggerProvideris registered — e.g.@smooai/observability's new logs signal. With no provider registeredlogs.getLogger()is the api-logs no-op, so the bridge is cheap and stdout output is unchanged. Wrapped so telemetry can never break app logging.Depends only on the
@opentelemetry/api+@opentelemetry/api-logsfacades — no SDK dependency and no circular dep on@smooai/observability.Verification
tsc --noEmitclean (full multi-langtypecheckalso green),tsdownbuild clean, oxlint clean, 57/57 vitest tests pass.Logger.otel.spec.tsis a real-SDK round-trip: logs inside a real active span (real tracer + async-hooks context manager + realLoggerProvider/InMemoryLogRecordExporter) and asserts the span's real 32/16-hex ids appear in both the stdout JSON object and the bridged OTLP record; the no-span case asserts the uuid fallback + nospanId+ an uncorrelated record.🤖 Generated with Claude Code
