+# KiddOs v3 — React Hot Reload OS (Done)
+
+**Browser kiosk + React + Vite HMR, no backend, no LVGL, offline-first.**
+
+This is the finished v3 you'd been building. Just React, hot refresh, works on 800×480 DSI.
+
+## What works now
+
+- **React shell** `src/App.jsx`: header with clock, greeting, companion banner, favorites & recent (localStorage), category filters, 150px cards grid, settings drawer
+- **7 apps** (all React components, no fork/exec):
+  - `Journal` — autosave 1.5s, word count, past list, companion banner, offline localStorage
+  - `Calculator` — touch 56px buttons, history in localStorage
+  - `Drawing` — canvas pen/eraser, size, undo, save PNG, works touch+mouse
+  - `CodeLab` — JS playground, 3 samples, auto-saves, safe `new Function`
+  - `Clock` — analog time, timer (1/3/5/10m), stopwatch
+  - `Files` — browse localStorage journal entries, show companion info
+  - `Scratch` — iframe scratch.mit.edu (needs online) + offline alternatives info
+- **Styling**: dark #2E3440 Nord theme, 800×480 optimized, touch 36px+ targets
+- **Hot reload**: Vite dev server on :5173, Cog loads http://localhost:5173, edits push <1s to DSI
+- **Build**: 184KB JS, 55KB gzip, no backend, file:// also works via `dist/`
+
+## How to run (proven commands)
+
+**1. Stop old kiosks:**
+```bash
+sudo systemctl stop kiddos.service kiddos-browser.service journal-kiosk.service
+```
+
+**2. Start React dev server (SSH session 1):**
+```bash
+cd ~/KiddOsV3/webapp
+npm run dev -- --host 0.0.0.0 --port 5173
+# or
+~/KiddOsV3/scripts/dev.sh
+```
+Vite: `Local: http://localhost:5173/`
+
+**3. Put on DSI (SSH session 2):**
+```bash
+~/KiddOsV3/scripts/run-kiosk.sh
+# which runs:
+sudo openvt -f -c 1 -s -- env XDG_RUNTIME_DIR=/run/user/1000 cage -s -- \
+  cog --platform=wl http://localhost:5173 --bg-color=#2E3440 --doc-viewer
+```
+
+You should see React launcher on DSI, touch works (ft5x06 event7 via libinput seat0). Edit `src/App.jsx`, save, DSI updates instantly.
+
+**Fallbacks:**
+```bash
+# Chromium if Cog touch cursor stuck middle
+sudo openvt -f -c 1 -s -- env XDG_RUNTIME_DIR=/run/user/1000 cage -s -- \
+  chromium --kiosk --no-sandbox --ozone-platform=wayland --disable-gpu http://localhost:5173
+
+# Static prod build (no dev server)
+cd ~/KiddOsV3/webapp && npm run build
+cage -s -- cog --platform=wl file://$PWD/dist/index.html --bg-color=#2E3440
+
+# Hello world test (no React)
+cage -s -- cog --platform=wl file:///home/elias/KiddOsV2/browser/hello.html --bg-color=#2E3440
+```
+
+**If touch cursor stuck middle:**
+- `libinput list-devices` should show `10-0038 generic ft5x06 (79)` at event7
+- cage needs it. Try without `WLR_NO_HARDWARE_CURSORS`, clean `/run/user/1000/wayland-*`
+- Or try labwc compositor instead of cage (heavier but more compatible)

+## Companion integration
+
+- `elias_companion` writes `~/launcher_config/companion_message.txt` and `dashboard.md` (counts only)
+- v3 reads `localStorage.kiddos_companion_message` if set
+- To show live companion on React:
+  ```bash
+  cat ~/launcher_config/companion_message.txt
+  # then in browser console:
+  localStorage.setItem('kiddos_companion_message', 'You wrote today - 1 entries!')
+  ```
+  Future: add tiny python server endpoint `/api/companion` in v2 `server/server.py` or copy companion_message.txt into `webapp/public/` and fetch.
+
+## Next steps (after prove)
+
+1. Confirm hot reload works on DSI (edit App.jsx, see instantly)
+2. Add more apps: Blockly offline (copy from v2), music, math games
+3. Optionally re-add `server/server.py` for central sync (v2's local-first + central)
+4. Only then systemd service using same working command (openvt -f -c 1 -s ...)
+
+## Why not LVGL anymore
+
+v1 LVGL had DRM master handover per app → “any app I try to open freeze and restarts the OS” (your report). Browser OS: one process owns DRM forever, apps are React components, no fork, no black screen.

+# KiddOs v3 — Plan: Browser Kiosk + React Hot Reload, No Backend
+
+## Goal
+From-scratch v3, **just webapp React with hot refresh**, no server, no LVGL, no backend. Use the proven kiosk command that shows web on DSI:
+
+```bash
+cage -s -- \
+cog --platform=wl file:///home/elias/KiddOsV2/browser/hello.html --bg-color=#2E3440
+```
+
+That command is Method 2a that you confirmed works: `cage` (tiny Wayland kiosk compositor, 82KB) owns DRM/KMS on `/dev/dri/card1` (DSI 800x480 connector id 49), creates Wayland socket in `$XDG_RUNTIME_DIR`, `cog --platform=wl` (WPE WebKit, ~10MB) connects as Wayland client and renders HTML. No X11, no black flicker from fork/exec.
+
+For v3 we keep that exact command, but point it to a **React dev server** for hot refresh instead of static file://
+
+## Why No Backend?
+- v2 had `server/server.py` local-first + central sync. Good architecture but adds complexity.
+- v3 requirement: **just webapp react with hot refresh on code changes so we can quickly iterate**.
+- So: Vite dev server on Pi itself `http://localhost:5173` serves React, Cog loads that URL, and Vite HMR pushes changes instantly to DSI — you edit `src/App.jsx` on laptop via SSH, DSI updates in <1s.
+
+## Stack
+- **Compositor**: `cage -s` (kiosk Wayland, handles DRM, libinput touch via seat0)
+- **Browser**: `cog --platform=wl` (WPE WebKit, lighter than Chromium 150MB and Electron 265MB). Fallback: `chromium --ozone-platform=wayland` if WPE touch fails.
+- **Webapp**: React 18 UMD or Vite + React (we use Vite for HMR). No backend, uses `localStorage` for journal/todos. All offline, file:// or http://localhost works.
+- **Icons**: Reuse PNG 128x128 from v1/v2 `browser/icons/`.

+    └── run-kiosk.sh (the proven cage command)
+```
+
+## How to run (prove without services)
+
+**On Pi, no services needed — manual, like you asked:**
+
+```bash
+# 1. Stop any old kiosks, leave terminal on DSI
+sudo systemctl stop kiddos.service kiddos-browser.service journal-kiosk.service
+sudo systemctl start getty@tty1.service
+
+# 2. Start React dev server in one SSH session:
+cd ~/KiddOsV3/webapp
+npm install
+npm run dev -- --host 0.0.0.0 --port 5173
+# Vite says: Local: http://localhost:5173/
+
+# 3. In another SSH session, put it on DSI (exact command you proved):
+sudo openvt -f -c 1 -s -- env XDG_RUNTIME_DIR=/run/user/1000 cage -s -- \
+cog --platform=wl http://localhost:5173 --bg-color=#2E3440 --doc-viewer
+
+# You should see React launcher on DSI, and editing src/App.jsx updates instantly.
+```
+
+**If touch cursor stuck middle (your last report):**
+- Cage needs input devices. Check `libinput list-devices` shows `10-0038 generic ft5x06 (79)` at event7.
+- Try without WLR_NO_HARDWARE_CURSORS, and ensure /run/user/1000/wayland-* cleaned.
+- Fallback: `cage -s -- chromium --ozone-platform=wayland` instead of cog — you saw webpage with that too.
+- Last resort heavier: `labwc --startup "cog ..."` or Xorg+openbox, but we avoid until proven.
+
+## React Hot Refresh Details
+- Vite HMR uses WebSocket on same host:port. Cog supports WebSocket, so HMR works file://? No, needs http:// — hence dev server at localhost:5173.
+- In `vite.config.js`:
+```js
+export default {
+  server: { host: '0.0.0.0', port: 5173, hmr: { clientPort: 5173 } },
+  clearScreen: false
+}
+```
+- Edit `src/App.jsx`, save, DSI refreshes.
+
+## Next Steps After Prove
+Once hello world React works reliably on DSI with touch:
+1. Add more React apps (Scratch via iframe?).
+2. Optionally re-add local server later for central sync (v2's server.py) — but keep v3 frontend-only for fast iteration.
+3. Only then create systemd service using same working command (openvt -f -c 1 -s ...).
+
+## Commands Reference (the one you asked to keep)
+
+Base proven command (no backend, just file:// hello world):
+```bash
+cage -s -- \
+cog --platform=wl file:///home/elias/KiddOsV2/browser/hello.html --bg-color=#2E3440
+```
+
+For v3 React with HMR:
+```bash
+cage -s -- \
+cog --platform=wl http://localhost:5173 --bg-color=#2E3440
+```
+
+If Cog touch fails, try Chromium:
+```bash
+cage -s -- \
+chromium --kiosk --no-sandbox --ozone-platform=wayland --disable-gpu \
+http://localhost:5173
+```
+
+Electron alternative (heavier, same as Chromium + Node, you asked about):
+```bash
+cage -s -- \
+./node_modules/.bin/electron --no-sandbox --ozone-platform=wayland --disable-gpu .
+```
+
+## Why not LVGL anymore?
+- v1 LVGL had to fork/exec + DRM master handover for each app → “any app I try to open freeze and restarts the OS” (your report). Non-DRM apps (gnome-calculator) crashed.
+- Browser OS: one process owns DRM forever, apps are just React components / pages, no fork, no black screen.
