## Boundaries

- Choose a host for each stage and verify its tool mapping. Pass evidence explicitly between stages; the listed resources do not automatically configure or invoke one another.

- The supplied agent’s tool aliases may require adaptation to your host and installed browser server.

- Do not let parallel workers drive the same browser session. Browser traces can contain private page content; inspect them before sharing.
