## 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.

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.)
