Human user interactions are human-authored new issue posts, human-authored new comments, and human reactions created during the window, including upvotes. Bot posts and bot reactions are excluded. In prose, explain this as high user interaction rather than naming the emoji.

   - You can run `just argument-comment-lint` to run the lint check locally. This is powered by Bazel, so running it the first time can be slow if Bazel is not warmed up, though incremental invocations should take <15s. Most of the time, it is best to update the PR and let CI take responsibility for checking this (or run it asynchronously in the background after submitting the PR). Note CI checks all three platforms, which the local run does not.
 - When possible, make `match` statements exhaustive and avoid wildcard arms.
 - Newly added traits should include doc comments that explain their role and how implementations are expected to use them.
+- Discourage both `#[async_trait]` and `#[allow(async_fn_in_trait)]` in Rust traits.
+  - Prefer native RPITIT trait methods with explicit `Send` bounds on the returned future, as in `3c7f013f9735` / `#16630`.
+  - Preferred trait shape:
+    `fn foo(&self, ...) -> impl std::future::Future<Output = T> + Send;`
+  - Implementations may still use `async fn foo(&self, ...) -> T` when they satisfy that contract.
+  - Do not use `#[allow(async_fn_in_trait)]` as a shortcut around spelling the future contract explicitly.
 - When writing tests, prefer comparing the equality of entire objects over fields one by one.
-- When making a change that adds or changes an API, ensure that the documentation in the `docs/` folder is up to date if applicable.
+- Do not add general product or user-facing documentation to the `docs/` folder. The official Codex documentation lives elsewhere. The exception is app-server API documentation, which is covered by the app-server guidance below.
 - Prefer private modules and explicitly exported public crate API.
 - If you change `ConfigToml` or nested config types, run `just write-config-schema` to update `codex-rs/core/config.schema.json`.
 - When working with MCP tool calls, prefer using `codex-rs/codex-mcp/src/mcp_connection_manager.rs` to handle mutation of tools and tool calls. Aim to minimize the footprint of changes and leverage existing abstractions rather than plumbing code through multiple levels of function calls.

+# codex-app-server-daemon
+
+> `codex-app-server-daemon` is experimental and its lifecycle contract may
+> change while the remote-management flow is still being developed.
+
+`codex-app-server-daemon` backs the machine-readable `codex app-server`
+lifecycle commands used by remote clients such as the desktop and mobile apps.
+It is intended for Codex instances launched over SSH, including fresh developer
+machines that should expose app-server with `remote_control` enabled.
+
+## Platform support
+
+The current daemon implementation is Unix-only. It uses pidfile-backed
+daemonization plus Unix process and file-locking primitives, and does not yet
+support Windows lifecycle management.
+
+## Commands
+
+```sh
+codex app-server daemon start
+codex app-server daemon restart
+codex app-server daemon enable-remote-control
+codex app-server daemon disable-remote-control
+codex app-server daemon stop
+codex app-server daemon version
+codex app-server daemon bootstrap --remote-control
+```
+
+On success, every command writes exactly one JSON object to stdout. Consumers
+should parse that JSON rather than relying on human-readable text. Lifecycle
+responses report the resolved backend, socket path, local CLI version, and
+running app-server version when applicable.
+
+## Bootstrap flow
+
+For a new remote machine:
+
+```sh
+curl -fsSL https://chatgpt.com/codex/install.sh | sh
+$HOME/.codex/packages/standalone/current/codex app-server daemon bootstrap --remote-control
+```
+
+`bootstrap` requires the standalone managed install. It records the daemon
+settings under `CODEX_HOME/app-server-daemon/`, starts app-server as a
+pidfile-backed detached process, and launches a detached updater loop.
+
+## Installation and update cases
+
+The daemon assumes Codex is installed through `install.sh` and always launches
+the standalone managed binary under `CODEX_HOME`.
+
+| Situation | What starts | Does this daemon fetch new binaries? | Does a running app-server eventually move to a newer binary on its own? |
+| --- | --- | --- | --- |
+| `install.sh` has run, but only `start` is used | `start` uses `CODEX_HOME/packages/standalone/current/codex` | No | No. The managed path is used when starting or restarting, but no updater is installed. |
+| `install.sh` has run, then `bootstrap` is used | The pidfile backend uses `CODEX_HOME/packages/standalone/current/codex` | Yes. Bootstrap launches a detached updater loop that runs `install.sh` hourly. | Yes, while that updater process is alive and app-server is already running. After a successful fetch, the updater restarts app-server with the refreshed binary and only then replaces its own process image. |
+| Some other tool updates the managed binary path | The next fresh start or restart uses the updated file at that path | Only if `bootstrap` is active, because the updater still runs `install.sh` on its normal cadence. | Without `bootstrap`, no. With `bootstrap`, the next successful updater pass compares the managed binary contents after `install.sh` runs; if app-server is running and they differ from the updater's current image, it refreshes app-server first and then itself. |
+
+### Standalone installs
+
+For installs created by `install.sh`:
+
+- lifecycle commands always use the standalone managed binary path
+- `bootstrap` is supported
+- `bootstrap` starts a detached pid-backed updater loop that fetches via
+  `install.sh`
+- after a successful refresh, if app-server is running and the managed binary
+  contents changed, the updater restarts app-server with that binary first and
+  only then replaces its own process image
+- the updater loop is not reboot-persistent; it must be started again by
+  rerunning `bootstrap` after a reboot
+
+### Out-of-band updates
+
+This daemon does not watch arbitrary executable files for replacement. If some
+other tool updates the managed binary path:
+
+- without `bootstrap`, a currently running app-server remains on the old
+  executable image until an explicit `restart`
+- with `bootstrap`, the detached updater loop notices the changed managed
+  binary on its next successful scheduled pass after running `install.sh`; if
+  app-server is running, it refreshes app-server first and then refreshes itself
+  once that replacement starts successfully
+
+## Lifecycle semantics
+
+`start` is idempotent and returns after app-server is ready to answer the normal
+JSON-RPC initialize handshake on the Unix control socket.
+
+`restart` stops any managed daemon and starts it again.
+
+`enable-remote-control` and `disable-remote-control` persist the launch setting
+for future starts. If a managed app-server is already running, they restart it
+so the new setting takes effect immediately.
+
+Top-level `codex remote-control` bootstraps with `--remote-control` when the
+updater loop is not running. Otherwise it enables remote control and starts the
+daemon normally.
+
+`stop` sends a graceful termination request first, then sends a second
+termination signal after the grace window if the process is still alive.
+
+All mutating lifecycle commands are serialized per `CODEX_HOME`, so a concurrent
+`start`, `restart`, `enable-remote-control`, `disable-remote-control`, `stop`,
+or `bootstrap` does not race another in-flight lifecycle operation.
+
+## State
+
+The daemon stores its local state under `CODEX_HOME/app-server-daemon/`:
+
+- `settings.json` for persisted launch settings
+- `app-server.pid` for the app-server process record
+- `app-server-updater.pid` for the pid-backed standalone updater loop
+- `daemon.lock` for daemon-wide lifecycle serialization
