/**
 * Browser/computer-use *discoverability* asserts on the sub-agent protocol.

 * The protocol is injected into every sub-agent. If a future copy edit
 * accidentally tells sub-agents "ask the user to fill the form" instead of
 * using the dedicated credential setup flows, those sub-agents will silently
 * stop preserving secret handling. These asserts pin the surviving guardrails
 * without acquiring new ones that suppress active discovery.
