## What
Exposes the pairing status transport as experimental app-server v2 RPC
`remoteControl/pairing/status`.
- Adds request/response protocol types for exactly one lookup key:
`pairingCode` or `manualPairingCode`, returning `{ claimed }`.
- Registers the RPC with `global_shared_read("remote-control-pairing")`.
- Wires the method through `MessageProcessor` and
`RemoteControlRequestProcessor`.
- Validates missing/conflicting pairing-code params as invalid requests.
- Documents the RPC in `app-server/README.md`.
- Adds processor, protocol export, and JSON-RPC integration coverage for
both code paths.
## Why
This is the app-server surface the desktop app can poll while the
QR/manual pairing modal is active.
Depends on https://github.com/openai/codex/pull/26449

## Verification
- `cargo test --manifest-path app-server-protocol/Cargo.toml
remote_control`
- `cargo test --manifest-path app-server/Cargo.toml remote_control`
- `cargo fmt --all --check`
- `git diff --check`
## Why
`remoteControl/pairing/start` creates authorization for future
remote-control connections, so it should not require the live websocket
to already be enabled. Requiring enable first made pairing depend on
presence instead of the persisted server enrollment that pairing
actually uses.
Pairing also needs to recover when that persisted server row is stale.
If `/server/pair` returns `404`, making the first pairing attempt fail
forces a manual retry even though the client can clear the stale row and
create a replacement enrollment immediately.
## What Changed
- Allow `remoteControl/pairing/start` to reuse or create the persisted
remote-control server enrollment while remote control is disabled.
- Keep the selected in-memory enrollment across disable and share it
with websocket connect so a later enable uses the same selected server.
- Thread the app-server client name through pairing so stdio persistence
keeps using the websocket-owned enrollment key.
- Recover pairing server-token auth failures through the existing
refresh/auth-recovery path.
- Recover stale pairing enrollment on `/server/pair` `404` by clearing
the stale selected enrollment, re-enrolling once, and retrying pairing
once.
- Add focused disabled-pairing and stale-pairing recovery coverage.
## Verification
-
`remote_control_pairing_start_returns_pairing_artifacts_while_disabled`
exercises pairing before enable.
- `remote_control_handle_reenrolls_after_stale_pairing_enrollment`
exercises stale `/server/pair` `404` recovery without a manual retry.

## Why
Remote-control clients need to list and revoke controller-device grants
without enabling or enrolling the local relay. These are signed-in
account-management operations, so coupling them to websocket, pairing,
enrollment, or persisted relay state would prevent clients from managing
stale grants from the picker.
Related enhancement request: N/A. This adds the Codex app-server surface
for the planned upstream environment-scoped revoke endpoint.
## What Changed
- Added experimental app-server v2 RPCs:
- `remoteControl/client/list`
- `remoteControl/client/revoke`
- Added picker-oriented protocol types and standard generated schema
fixtures. The list response intentionally omits backend account id,
enrollment status, and location fields.
- Added `app-server-transport/src/transport/remote_control/clients.rs`
for environment-scoped GET and DELETE requests. It builds escaped URL
path segments, forwards optional pagination query fields, sends ChatGPT
auth plus `chatgpt-account-id`, converts RFC3339 `last_seen_at` values
to Unix seconds, accepts `204 No Content` revoke responses, and retries
once after a `401`.
- Extracted shared ChatGPT auth loading and recovery into
`app-server-transport/src/transport/remote_control/auth.rs` so
websocket, pairing, and client management use the same account-auth
boundary.
- Retained the configured remote-control base URL on
`RemoteControlHandle` and resolve management URLs lazily, preserving
deferred validation while relay startup is disabled.
- Registered list as `global_shared_read("remote-control-clients")` and
revoke as `global("remote-control-clients")`.
## Verification
- Added transport coverage proving list and revoke work while relay
state is disabled, IDs are escaped, picker-only fields are returned,
timestamps are converted, revoke accepts `204`, auth headers are
forwarded, `401` retries exactly once, `403` is not retried, and
malformed list payloads retain decode context.
- Added an app-server integration test proving both JSON-RPC methods
work before relay enablement and successful revoke returns `{}`.
- Regenerated and validated experimental and standard app-server schema
fixtures.
## Why
Remote control enrollment authorizes a desktop server, but app-server v2
did not expose the follow-up pairing operation needed to mint a
short-lived controller pairing artifact from that enrolled server.
Clients need a narrow RPC that starts pairing without exposing the
backend `serverId` or conflating pairing with websocket connection
state.
Issue: N/A; internal remote-control pairing API change.
## What Changed
Added experimental app-server v2 `remoteControl/pairing/start` with
`manualCode` input and `pairingCode`, nullable `manualPairingCode`,
`environmentId`, and Unix-seconds `expiresAt` output. The method
serializes under its own `global("remote-control-pairing")` scope and is
documented in `app-server/README.md`.
Extended the remote-control transport with private `/server/pair`
request/response types and normalized `pair_url` handling. Pairing uses
the current enrolled server bearer, refreshes that bearer when needed,
keeps backend `server_id` private, validates returned `server_id` and
`environment_id` against the current enrollment, and preserves backend
status/header/body context for failures and malformed responses.
Wired the request through `RemoteControlRequestProcessor` and
`MessageProcessor`, mapping unavailable/disabled pairing to
`invalid_request` and backend failures to internal errors.
## Verification
- `just test -p codex-app-server-transport`
- `just test -p codex-app-server
remote_control_pairing_start_returns_pairing_artifacts`
This PR brought to you via VS Code rather than Codex...
- opened `codex-rs/app-server/tests/common/mcp_process.rs`
- put the cursor on `McpServer`
- hit `F2` and renamed the symbol to `TestAppServer`
- went to the file tree
- hit enter and renamed `mcp_process.rs` to `test_app_server.rs`
- ran **Save All Files** from the Command Palette
- ran `just fmt`
The End
(Admittedly, most of the local variables for `TestAppServer` are still
named `mcp`, though.)
## Why
To help improve `codex remote-control` CLI UX which I plan to do in a
followup, this PR adds `server-name` to the various remote control APIs:
- `remoteControl/enable`
- `remoteControl/disable`
- `remoteControl/status/changed`
Also, add a `remoteControl/status/read` API. This will be helpful in the
Codex App.
## Why
reapplies https://github.com/openai/codex/pull/22386 which was
previously reverted
Also, introduce `remoteControl/enable` and `remoteControl/disable`
app-server APIs to toggle on/off remote control at runtime for a given
running app-server instance.
## What Changed
- Adds experimental v2 RPCs:
- `remoteControl/enable`
- `remoteControl/disable`
- Adds `RemoteControlRequestProcessor` and routes the new RPCs through
it instead of `ConfigRequestProcessor`.
- Adds named `RemoteControlHandle::enable`, `disable`, and `status`
methods.
- Makes `remoteControl/enable` return an error when sqlite state DB is
unavailable, while keeping enrollment/websocket failures as async status
updates.
- Adds `AppServerRuntimeOptions.remote_control_enabled` and hidden
`--remote-control` flags for `codex app-server` and `codex-app-server`.
- Updates managed daemon startup to use `codex app-server
--remote-control --listen unix://`.
- Marks `Feature::RemoteControl` as removed and ignores
`[features].remote_control`.
- Updates app-server README entries for the new remote-control methods.
