Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Add a new `remote-ui/square/` variant of the SecuBox Eye Remote, targeting Raspberry Pi 4 Model B and Raspberry Pi 400 (BCM2711, arm64) with the official Raspberry Pi 7" Touchscreen V1.1 (DSI, 800×480, 10-point capacitive). Boots a dual-pane kiosk: round UI (consumed verbatim from `remote-ui/common/` + `remote-ui/round/index.html`) renders at (0, 0, 480, 480) in Chromium; a native PySide6 right column renders at (480, 0, 320, 480) with four tabs (Alerts, Module Detail, Console, Mode Controls). USB-C peripheral mode (dwc3 via `dwc2,dr_mode=peripheral` overlay) is configured and active when the board is powered via GPIO 5V. + +**Architecture:** Two OS-level windows pinned by Openbox on X11 — no `square/index.html` page. IPC: Chromium's TransportManager fires `module:tap` / `transport:status` events over `ws://127.0.0.1:9090/eye-square` to a server hosted by the PySide6 process. Privileged operations (USB gadget mode switch, service restart, console tail, lockdown) live in a separate `secubox-eye-square-helper` FastAPI on a Unix socket `/run/secubox/eye-square-helper.sock` with `SO_PEERCRED` auth and `CAP_NET_ADMIN` + `CAP_SYS_ADMIN` capabilities. The right panel calls the helper for privileged work, and reads metrics/alerts directly from the SecuBox host API via the same TransportManager state Chromium uses. + +**Tech Stack:** Python 3.11 + PySide6 (LGPL Qt for Python) + qasync + websockets, FastAPI + uvicorn on Unix socket, Chromium kiosk, Openbox on X11, Debian Bookworm arm64, systemd, nftables, configfs USB gadget, debootstrap + qemu-aarch64-static for the image build. + +**Spec:** [`docs/superpowers/specs/2026-05-13-eye-square-variant-design.md`](../specs/2026-05-13-eye-square-variant-design.md) +**Issue:** [#127](https://github.com/CyberMind-FR/secubox-deb/issues/127) +**Predecessor:** Phase 1 PR [#130](https://github.com/CyberMind-FR/secubox-deb/pull/130) **must be merged before Phase 2 starts**.

Every Python and shell snippet is complete code, every test is concrete, every config block has real content. ✓ + +3. **Type consistency:** `HelperClient.set_usb_mode/restart_service/lockdown` signatures match the FastAPI route schemas (ModeRequest, RestartRequest, LockdownRequest). `IPCBridge.on_module_tap` / `on_transport_change` signatures match the events sent by `square-bridge.js`. `RightPanelWindow.tabs` is `QTabWidget` referenced consistently. ✓ + +4. **Ambiguity:** The udev rule's idVendor:idProduct values are inherited from round/'s gadget; reviewer should confirm at Task 17 Step 2 against the actual `secubox-otg-gadget.sh` setup. The pytest `test_console_ws_connects` test mocks the stream — full WS integration test against a real Unix socket would need a Task 25-like harness; flagged as suggested follow-up. ✓
