Browser Quickstart
This is the core BCTRL browser flow:
- Create a space.
- Launch a browser runtime.
- Create a CDP connection.
- Use your native browser framework.
- Inspect the current run.
What happened
- The space became the permission boundary for the work.
- The runtime hosted a real browser.
- The connection gave Playwright a temporary CDP endpoint.
- The run captured events, commands, artifacts, live view, and recording metadata.
