Enable Workers Logs, Wrangler tail, and Logpush for Preview URL requests

[roduyemi]

The https://developers.cloudflare.com/workers/configuration/previews/#limitations doc states:

You cannot view logs for Preview URLs today, this includes Workers Logs, Wrangler tail and Logpush.

We use Worker Versions with preview aliases (wrangler versions upload --preview-alias) to deploy multiple development branch versions of the same worker. However, we have zero server-side observability for these preview deployments — no console.log
output, no error traces, no request logs.

The dashboard shows a "Logs" tab and observability options for each version, but no data is ever captured for preview URL requests.

Describe the solution you'd like

Preview URL requests should generate the same telemetry as regular deployment requests:

• Visible in Workers Logs (dashboard)
• Capturable via wrangler tail
• Exportable via Logpush / Workers Trace Events
• Compatible with Tail Workers

The docs mention "today" suggesting this is a known gap being worked on. Any timeline or status update would be appreciated 🙏🏿
