…r config The Vite plugin already knows which bindings resolve to receivers it instruments itself: Durable Object bindings without a `script_name`, and service bindings naming this worker. Those are exactly the bindings whose trailing trace argument is guaranteed to be stripped again, so the plugin adds them to `rpcTracePropagationBindings` and same-deployment RPC traces connect without any configuration. Bindings to other workers stay opt-in. Only bindings whose receiver class the transform wrapped itself are added. A class the user wrapped by hand, or re-exported from another module, runs on its own options and cannot be assumed to strip the argument. The options object only exists once the callback runs with `env`, so the plugin cannot merge at build time. The transform emits an inline callback that wraps the user's one and merges the binding names, so no runtime helper export is needed. Note this default only applies to Vite builds. At runtime a DurableObjectNamespace exposes no origin and a Fetcher does not say which service it points at, so a plain wrangler build still has to list its bindings.

…as auto-wrapped `export default Foo`, where a named export already wrapped `Foo`, skips wrapping to avoid `withSentry(withSentry(...))`, but the binding still points at the wrapped class. Mark the default export as auto-wrapped so an entrypoint-less self service binding survives into `rpcTracePropagationBindings`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…ngler config (#23738) Backport of: #23491 ## Differences to the original PR - `packages/cloudflare/src/vite/transform.ts`: the generated options callback also sets `enableRpcTracePropagation: opts?.enableRpcTracePropagation ?? true`. On v10 the receiver still reads that option to continue an incoming trace, and the plugin wrapped those receiver classes itself, so it can turn it on. An explicit value in the user's options wins. Without it the derived bindings would propagate but no receiver span would be created. - `packages/cloudflare/src/vite/index.ts` and the new integration suite's `vite.config.mts`: `autoInstrumentation` lives under `_experimental` on v10, so the doc paragraph and the test config use that shape.

The Vite plugin already knows which bindings resolve to receivers it instruments itself: Durable Object bindings without a
