Research direction
No files or tests are named. Start by locating the cacheComponents handling and the browser/server trace-context entry points, then inspect how cached shell HTML and dynamic holes are rendered. Done means pageload trace X and server trace Y reconnect without replaying stale context from the cached shell, with coverage for a cacheComponents page.
Written by the indexing model from the issue text.
Description
Example: any cacheComponents page. The browser records pageload trace X, the server records request trace Y, and they never meet. The SDK currently disables the sentry-trace meta tags. because the shell HTML is cached and baked-in context would replay one stale trace to every visitor. Result: two orphan traces per visit. A slow pageload cannot be followed into its server work.
Solves: the incomplete-traces complaint. This is the gap users notice first.
Fix idea: carry trace context only in the part of the response that is never cached. For example, a small component rendered inside a dynamic hole streams the meta tag or script with trace Y's context, and the browser SDK picks it up. The prerendered shell stays context-free. This sketch has no prototype behind it yet - research this first.
