 - The Docker runner lives at `scripts/test-live-acp-bind-docker.sh`.

The ACP backend itself is the bundled embedded `acpx/runtime` package from the `acpx` plugin.
+- The Droid Docker variant stages `~/.factory` for settings, forwards `FACTORY_API_KEY`, and requires that API key because local Factory OAuth/keyring auth is not portable into the container. It uses ACPX's built-in `droid exec --output-format acp` registry entry.
 - The OpenCode Docker variant is a strict single-agent regression lane. It writes a temporary `OPENCODE_CONFIG_CONTENT` default model from `OPENCLAW_LIVE_ACP_BIND_OPENCODE_MODEL` (default `opencode/kimi-k2.6`) after sourcing `~/.profile`, and `pnpm test:docker:live-acp-bind:opencode` requires a bound assistant transcript instead of accepting the generic post-bind skip.
 - Direct `acpx` CLI calls are only a manual/workaround path for comparing behavior outside the Gateway. The Docker ACP bind smoke exercises OpenClaw's embedded `acpx` runtime backend.

 If you ask OpenClaw in plain language to bind or control Codex in the current conversation and the bundled `codex` plugin is enabled, OpenClaw should use the native Codex app-server plugin (`/codex bind`, `/codex threads`, `/codex resume`, `/codex steer`, `/codex stop`) instead of ACP. If you ask for `/acp`, ACP, acpx, or an ACP adapter test explicitly, OpenClaw can still route Codex through ACP. Each ACP session spawn is tracked as a [background task](/automation/tasks).
