 Codex runs with its own home, `codex` under the data directory (`CODEX_HOME`, set by `startCodex`), so the human's `~/.codex/config.toml` (its `notify` program, MCP servers and plugins) doesn't apply and byre's threads stay out of the ChatGPT app's history. That home needs its own login, once: `CODEX_HOME="$HOME/Library/Application Support/byre/codex" codex login`. Until then a Codex turn fails with `401 Unauthorized`, filed as a session error. The `codex` binary comes from `PATH`; see `docs/codex-protocol.md`.

 ## Status
 
-`GET /api/admin/status` reports `running_turns` (task sessions now `running`, as session, task and vendor; lead turns aren't listed); `rate_limits`, the latest status each vendor sent since byre started (Claude's `rate_limit_info`, with `windowMins` added to each `unifiedWindows` entry by `addClaudeWindowMins` in `internal/agents/manager.go` from the window's name, since Claude doesn't send a length; Codex's `account/rateLimits/updated` reshaped by `codexRateLimit` in `internal/agents/codex.go` into the same `status`, `rateLimitType` and `unifiedWindows` fields, `windowMins` from its `windowDurationMins`). Claude only reports during its turns; Codex is also asked once at startup (`readCodexRateLimit`, a short-lived `codex app-server` that calls `account/rateLimits/read` without opening a thread), so its entry is there before any Codex turn runs, and every Codex update broadcasts `admin.health`; `agent_processes`, `zombies`, `stuck_after_seconds` and `protocol_errors` (below); `clients`, one entry per command channel byre holds (the `/api/clients/connect` WebSockets in `internal/clients`, see "Client Macs"), oldest first, so it lists exactly the Macs `list_clients` and the `client_*` tools can reach; a Mac whose event streams are open but whose command channel is down isn't listed. `id`, `host` and `commit` come from the `Byre-Client`, `Byre-Host` and `Byre-Commit` headers, which the macOS app sends on every request: a UUID the app makes up each time it starts, the Mac's name (`Host.current().localizedName`, else `ProcessInfo.processInfo.hostName`, the name agents' client tools take) and the `ByreCommit` that `mac/bundle.sh` stamped into its `Info.plist`. To check that a rebuilt app is running, compare each client's `commit` with the commit it was built from. `last_action_at` is when byre last received a request the human made from that client `id`: any request other than a `GET`, except the two the app sends on its own (`PUT /api/me/pane-focus` and `PUT /api/tasks/{taskId}/summary-read`, listed in `automaticRequests` in `internal/server/server.go`), and every binary message on a terminal WebSocket, which includes the replies SwiftTerm sends by itself to queries in the output (cursor position and the like). The `identify` middleware and `terminalInput` record it in the client registry's memory (`Registry.Acted` in `internal/clients`), so it is absent until that client's first action after byre starts. The registry keeps each client by `id` across command-channel drops, so a Mac that sleeps and reconnects keeps its `last_action_at`, and forgets a client 24 hours after it was last connected or acted, since an app that quit never comes back under that `id`. An action at least a second after the last one from that client that broadcast, every `GET /api/events` stream opening or closing, and every command channel connecting or disconnecting broadcasts an unstored `admin.clients` event (`clientsChanged`). And server counts (start time, agent processes, projects, active tasks, SSE clients, database size including WAL, last event seq).
