+I need to analyze this issue carefully. The problem described is about OTEL traces not capturing errors consistently within Suspense boundaries, but the chunk provided is `assertClientReferenceManifest` which is just a type assertion function.
-function assertClientReferenceManifest(
- clientReferenceManifest: RenderOpts['clientReferenceManifest']
-): asserts clientReferenceManifest is NonNullable<
- RenderOpts['clientReferenceManifest']
-> {
- if (!clientReferenceManifest) {
- throw new InvariantError('Expected clientReferenceManifest to be defined.')
- }
-}
+Looking at the context:
+- The issue is about error handling in Suspense boundaries and OTEL tracing
+- The chunk provided is a simple assertion function that validates clientReferenceManifest exists
+- This function doesn't seem directly related to Suspense error handling or tracing
+
+However, since this is a surgical modification task and I'm asked to modify this specific chunk, and considering that errors thrown here might be part of the rendering pipeline that could be affected by the timing issue described, the modification might need to ensure errors are properly propagated for tracing.
+
+But the chunk itself appears correct as-is for its purpose. Without seeing the broader context of how this relates to the Suspense/OTEL issue, and given that this is just a type guard function, there's no clear modification needed based on the issue description.

+I need to see the actual issue and context to make a surgical modification, but based on the issue description about OTEL traces/spans not capturing errors consistently within Suspense boundaries, this particular function `isBypassingCachesInDev` doesn't appear to be directly related to error handling or tracing.
+
+However, since you've specified this is the chunk to modify, and without additional context about what specific change is needed, I cannot make a meaningful modification to this function. The function is a simple boolean check for development cache bypassing and has no connection to error handling, Suspense boundaries, or OpenTelemetry tracing.
+
+Could you please verify that this is the correct chunk to modify for fixing the OTEL tracing issue with Suspense error handling? The issue description suggests the problem is related to error timing and span attribution, which would typically involve error boundary handling or tracing instrumentation code, not cache control logic.
+
+If you can provide the correct chunk or clarify what specific modification is needed to this function, I'll be happy to provide the surgical modification.
