// All Monitor scenarios drive the kandev backend with the mock-agent's new
// e2e:monitor_* directives, which reproduce claude-agent-acp's wire format
// without depending on the real Claude Code SDK. The kandev ACP adapter
// recognizes the registration banner, parses task-notification envelopes,
// strips the model's "Human:" echoes, and tracks live monitor state — those
// behaviours are unit-tested in the backend; this file asserts the full
// pipeline lands the right thing in the chat UI.
