📝 Walkthrough

Walkthrough

The platform network dispatcher now binds globalThis.fetch to globalThis and returns a PublicNetworkDispatcher. The workspace adds Miniflare and workerd build configuration. Tests cover detached dispatcher calls in Node and workerd for GET, streamed POST, and string POST requests.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to cc309

The proxy dispatcher now forwards requests successfully in workerd environments instead of failing from an invalid fetch receiver, with request forwarding covered for GET and POST bodies. No merge-blocking risk remains.
