 Requires Node.js >= 20.
 
+Public adapters currently shipped in the CLI: `claude-code`, `codex`, `opencode`, `pi`, `pi-rust`, and `openclaw`.
+ACP-backed adapter work is in progress internally, but adapters such as `codex-acp` are not user-visible until packaging and discover-first session reattachment are ready.

 ## Quick Start

 **agentctl will adopt ACP as its primary agent interface strategy.**
 
+### Rollout boundary
+
+This ADR describes the architectural direction, not a claim that ACP-backed adapters are already production-ready in the public CLI.
+
+Until an ACP adapter has:
+- a packaged/distributed bridge story (or explicit documented prerequisite), and
+- discover-first rediscovery / reattach semantics that survive a fresh CLI process or daemon restart,
+
+it should remain experimental and not be registered as a public adapter.
+
 ### Principles
 
 1. **Ride on ACP, don't fight it.** agentctl's CLI and internal APIs should align with ACP primitives (sessions, prompts, cancel, permissions). Where ACP provides a clean abstraction, use it rather than reinventing.
