-OTel-first node Client (SMOODEV-1067d).
-
-The Node Client no longer wraps a Smoo-native HTTP transport — it emits to OpenTelemetry natively. Every `captureException` / `captureMessage` becomes a span event on the active OTel span (or a synthetic one if none is active), with `SpanStatusCode.ERROR` for exceptions and OTLP-shaped attributes (`enduser.id`, `enduser.org_id`, `service.version`, `deployment.environment.name`, `smoo.tag.*`, `smoo.event_id`, `smoo.level`). The OTel SDK handles batching, retry, and wire format; the Smoo SDK does not run a parallel HTTP pipeline on Node.
-
-`@smooai/logger` is now optional. The Smoo SDK has no compile-time dependency on it. When present, its CONTEXT global feeds OTel baggage (see `@smooai/observability-otel`). When absent, the OTel ambient context (W3C trace context propagation, baggage) is the single source of correlation truth — winston / pino / bunyan / console users get the same trace-id flowing through logs, traces, and Smoo error groups by reading `readOtelCorrelation()`.
-
-Breaking changes (`@smooai/observability` 0.3 → 0.4):
-
-- `makeNodeTransport` (re-exported from the `node` entry) removed — no longer needed; OTel SDK is the transport.
-- `Client._registerTransport` is now a no-op on Node when a capture handler is registered (which happens by default in `Client.init`). Browser is unchanged.
-- New seam `Client._registerCaptureHandler(handler | null)` for advanced consumers who want to plug in their own non-OTel capture path.
-
-Breaking changes (`@smooai/observability-otel` 0.1 → 0.2):
-
-- `bridgeClientToOtel()` removed. There's nothing to bridge — the Smoo Client already emits to OTel natively on Node. `setupOtelSdk()` and `readOtelCorrelation()` remain.
-
-Tests: 33 green on core (was 24), 5 on otel package. Typecheck + build clean.
