 Allowing `maps.googleapis.com` in `script-src` also trusts its JSONP endpoints, which can bypass the script allowlist if an HTML-injection bug exists; this is an accepted limitation of loading the Maps JavaScript API, alongside the existing `'unsafe-eval'` allowance.

+- **Typed chat spends the provider keys.** `/api/openai/chat` and `/api/gemini/chat` send the conversation to OpenAI Chat Completions or Gemini `generateContent` with the server's `OPENAI_API_KEY` or `GEMINI_API_KEY`. They require a same-site `Origin` (the Gemini request check), cap request bodies at 512 KB, refuse upstream redirects, cut the upstream call off after 60 s and return only sanitized errors. OpenAI chat can only bill `OPENAI_API_KEY`, so while `GEV_PREFER_CODEX_OAUTH` pins OpenAI to ChatGPT OAuth it refuses with `503` (`CODEX_OAUTH_REQUIRED`) rather than spend the key. After the provider refuses the key or account (a `401`, a `403`, Gemini's `400` `API_KEY_INVALID` or OpenAI's `429` `insufficient_quota`), a route stops sending that key upstream for a minute, or until the key changes.
 - **ChatGPT OAuth voice reuses the local Codex sign-in.** `/api/realtime/oauth-status`, `/api/realtime/oauth-login` and `/api/realtime/token?auth=oauth` answer only loopback connections, behind the same cross-site gate as the token endpoint; the login route also refuses a foreign `Origin`. None of them returns the access token. The login route runs `codex login` (or the executable named by `CODEX_BIN`) with an allowlisted environment that leaves out GEV's provider keys, keeps one attempt pending at a time and cancels it after two minutes or when the server stops. **Limits:** any program on this machine that can reach the server can mint Realtime sessions on the signed-in ChatGPT account, as it can with the API key; a local reverse proxy that hides the client's address defeats the loopback check; and OpenAI has not documented this use of Codex credentials for Realtime, so it may stop working or fall outside the account's terms.

 Voice controls bind to a protocol-independent session factory. The default WebRTC adapter preserves the existing Realtime connection, push-to-talk, cost controls and radio handoff. Session subscriptions expose state, transcript, action call/progress/result, interruption, completion and turn-metrics events; stopping or replacing a session cancels pending actions. An active session's normal Stop publishes one idle transition, including adapters that emit their own terminal state; a restart triggered by that transition keeps ownership of its new startup state. Alternate adapters can use the same controls and action runner.

Switching providers ends the old conversation and releases its microphone and connection; only the input mode carries over.

 - Map Source lives in the bottom Visual Presets tray. The left accordion contains no MAP STACK panel, and the `k` panel token that addressed it is gone from the share registry, so legacy `ui=k...` state takes the ordinary unknown-token skip.
 - A dock popover (Visual Presets, Location) auto-dismisses on mouse-away unless pinned. Focus inside the tray defers that dismissal only when the browser reports `:focus-visible` — keyboard focus and typed-into fields hold the tray open; a mouse-clicked tile does not, because Chromium focuses a `<button>` on press.

 - The desktop right rail (`#right-context-rail`) owns `DISPLAY`, `CCTV`, its active parameter controls, and `GLOBAL CONTEXT` as one fixed responsive stack in that order. Its compact buttons use the same 176 px width as the left accordion and one consistent 50 px height, share the left stack's 52 px edge inset and measured top baseline across HUD variants, then constrain themselves against visible HUD/chrome rectangles and the remaining vertical corridor. `DISPLAY` is no longer draggable and legacy saved coordinates are ignored.
 - The right rail is labeled **DISPLAY** (formerly "MOVE") and groups, in order, HUD, DETECT, Bloom, Sharpen, 3D, Clean-UI (HUD + DETECT promoted to the top). Its expanded controls retain the same compact 176 px width as the right-side tabs instead of growing to the wider Context detail-card width. It starts expanded on first run and respects the user's later `v6` collapse choice. Collapses/expands with directional chevrons (`◀` collapsed, `▶` expanded).

One right-rail panel is open at a time in every HUD layout and collapsed launchers are hidden; the panel rail beside the stack switches between them (see Panel rails). The most recently opened right-rail panel owns the lane even when it appears later in DOM order; passive restoration and automatic disclosure do not replace that explicit owner.
