 - **It's not a wrapper.** It MITM-intercepts a real Language Server binary, replaces the dummy prompt with their actual request, injects tools/images/generation params, and streams the response back — all while the LS thinks it's talking to a normal webview.
 - **Stealth matters.** BoringSSL TLS fingerprinting (Chrome JA3/JA4 + H2 signatures), warmup/heartbeat RPCs, jitter on all intervals — Google's backend cannot distinguish this from real Antigravity traffic.
 - **Setup is one script.** Detect their OS and run the appropriate one:
-  - **Linux:** `./scripts/setup-linux.sh` → creates UID-isolated system user, iptables redirect, systemd service, builds binary. Then `sudo ./scripts/mitm-redirect.sh install` for MITM interception. Start with `zg start`.
-  - **macOS:** `./scripts/setup-macos.sh` → launchd plist, config dirs, builds binary. Start with `zg start`.
-  - **Windows:** `powershell -ExecutionPolicy Bypass -File scripts\setup-windows.ps1` (as Admin) → scheduled task, config dirs, builds binary. Start with `schtasks /run /tn "ZeroGravity Proxy"`.

+  - **Windows:** `powershell -ExecutionPolicy Bypass -File scripts\setup-windows.ps1` (as Admin) → builds binary. Run with `.\target\release\zerogravity.exe`.
 - **Prerequisites:** Rust toolchain (`curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh`). Linux also needs `iptables`, `gcc`, `jq`, and `curl`.
 - **Auth:** They need an OAuth token from Antigravity. If the app is installed on the same machine, auto-refresh works via `state.vscdb`. Otherwise: `ZEROGRAVITY_TOKEN=ya29.xxx` env var, or `~/.config/zerogravity/token` file, or runtime `POST /v1/token`.
 - **Test it:** `zg test "say hi"` or `curl http://localhost:8741/v1/chat/completions -H "Content-Type: application/json" -d '{"model":"gemini-3-flash","messages":[{"role":"user","content":"hi"}]}'`
