 # Changelog
 
+## 2026.1.11-1
+
+### New Features and Changes
+- Agents/Browser: add `browser.target` (sandbox/host/custom) with sandbox host-control gating via `agents.defaults.sandbox.browser.allowHostControl`, and expand browser tool docs (remote control, profiles, internals).

 - **Remote CDP:** set `browser.profiles.<name>.cdpUrl` (or `browser.cdpUrl`) to

+## Remote browser (control server)
+
+You can run the **browser control server** on another machine and point your
+Gateway at it with a remote `controlUrl`. This lets the agent drive a browser
+outside the host (lab box, VM, remote desktop, etc.).
+
+Key points:
+- The **control server** speaks to Chrome/Chromium via **CDP**.
+- The **Gateway** only needs the HTTP control URL.
+- Profiles are resolved on the **control server** side.
+
+Example:
+```json5
+{
+  browser: {
+    enabled: true,
+    controlUrl: "http://10.0.0.42:18791",
+    defaultProfile: "work"
+  }
+}
+```
+
+Use `profiles.<name>.cdpUrl` for **remote CDP** if you want the Gateway to talk
+directly to a Chrome instance without a remote control server.

+## How it works (internal)
+
+High-level flow:
+- A small **control server** accepts HTTP requests.
+- It connects to Chrome/Chromium via **CDP**.
+- For advanced actions (click/type/snapshot/PDF), it uses **Playwright** on top
+  of CDP.
+- When Playwright is missing, only non-Playwright operations are available.

+## Agent tools + how control works
+
+The agent gets **one tool** for browser automation:
+- `browser` — status/start/stop/tabs/open/focus/close/snapshot/screenshot/navigate/act
+
+How it maps:
+- `browser snapshot` returns a stable UI tree (AI or ARIA).
+- `browser act` uses the snapshot `ref` IDs to click/type/drag/select.
+- `browser screenshot` captures pixels (full page or element).
+- `browser` accepts:
+  - `profile` to choose a named browser profile (host or remote control server).
+  - `target` (`sandbox` | `host` | `custom`) to select where the browser lives.
+  - `controlUrl` sets `target: "custom"` implicitly (remote control server).
+  - In sandboxed sessions, `target: "host"` requires `agents.defaults.sandbox.browser.allowHostControl=true`.
+  - If `target` is omitted: sandboxed sessions default to `sandbox`, non-sandbox sessions default to `host`.
+
+This keeps the agent deterministic and avoids brittle selectors.
