Resolved (2) · Dismissed (0)

• Resolved: Event type prefix inconsistent with all documented event types · File at PR head now uses the cf. prefix in all three examples (cf.browserRun.crawl.started/updated/finished at lines 29, 62, 89), matching the cf. prefix of all other event sources like cf.r2.bucket.created.
• Resolved: source example omits the type field · File at PR head now shows "source": { "type": "browserRun" } in all three examples (lines 30-32, 63-65, 90-92), matching other event examples like {"type": "r2"} and the --source browserRun subscription command.
