no this is fixed in next 16.3
Removes the `traceLifecycle: 'static'` pins and rewrites the specs onto streamed spans. Tests asserting on children of a segment span (server components, DB instrumentation, middleware fetch, prefetch) use `collectStreamedSpans` and accumulate until the segment, which ends last. The route-handler specs correlate an error or message event with its server span; those match the span on the event's own trace, so batching cannot pair spans across specs. `http.client` span names are low cardinality under streaming, so the middleware fetch span is `GET localhost` rather than `GET http://localhost:3030/` - which also mattered for the matcher, since the old name was used as a predicate and would have hung rather than failed. Dropped, having no span v2 equivalent: - The middleware isolation-scope assertions, including the guard that middleware tags do not leak onto the following route span. Span v2 carries no scope tags, so neither the tag nor its absence is observable. - The middleware `breadcrumbs` assertion. The fetch stays covered by its `http.client` span. - The `contexts.runtime.name` matchers, which only disambiguated uniquely named spans. Request headers carry over as `http.request.header.*` attributes, so the route-handler and pageload header assertions keep their coverage.

nextjs-16to span streaming: removes thetraceLifecycle: 'static'pins and rewrites the specs onto streamed spans, usingcollectStreamedSpanswhere a test asserts on children of a segment span.Route-handler specs match the server span on the event's own trace so batching cannot pair spans across specs.
http.clientspan names are low cardinality under streaming (GET localhost), which also mattered for the old name being used as a matcher.The middleware isolation-scope and breadcrumb assertions were dropped, having no span v2 equivalent.
nextjs-16-static(#23834) keeps the transaction-based versions of these specs.Ref #23802
