Just double checking, if this is prerendered during the build, we get no tx here right? Can we reflect this in the test?

yes, if it would be pre-rendered during build. This page is partially pre-rendered so a server transaction should exist.

What is a live serving request?

The serving request is always the one which is creating the cache, in this case the server. I'll reword that :D

Add a test for the pageload half of the complete-trace experience under
cacheComponents: the browser pageload should share a trace with the runtime server (serving) request, even though the shell is prerendered.Reference (stale-trace stitching): #18176
The trace context should not be added to the cachable HTML.
Currently in a "failed" state (
test.fail()) as trace meta tags are disabled wholesale undercacheComponentsand the pageload starts a fresh trace.Note for the switch flip: the inverse assertion in
cacheComponents.spec.ts("Prerendered shell does not stitch the pageload onto a stale trace") documents today's behavior and must be removed when this test starts passing.closes #24733
