Summary

  • remove runtime.configure and runtime.loopback_status from the public protocol
  • move protocol metadata, logging, telemetry, and optional browser CDP handoff into stagehand.init
  • make stagehand.init the first Stagehand RPC in TypeScript and Python
  • preserve explicit-CDP local and custom-browser behavior

Scope

Stack 1/6, targeting v4-spike directly. This PR changes only the initialization contract and client handoff; it does not add resident transport or worker lifecycle behavior.

Review focus

Browserbase can omit a CDP URL once later PRs supply an already-connected resident session. Local and custom sources continue to pass their resolved CDP URL through stagehand.init.

Validation

  • protocol, TypeScript SDK, Python SDK, runtime, and RPC coverage
  • exact Python formatting, lint, generated-model, and test checks
  • complete TypeScript/package/rule suite at the stack tip
