 11. **WebDAV client** — replaced `webdav@5` npm package with vendored `webdav-component` (browser-native `fetch` + `DOMParser`, no external deps). All pages import from `webdav.ts` abstraction layer.
 12. **WebDAV path fixes** — `webdav.ts`: always `decodeURIComponent` paths; use `entry.uri` (not broken `entry.path`) for servers returning relative hrefs
 13. **`webdav3.py` server fixes** — `displayname` now returns leaf name only (not full path); PROPFIND depth-1 guard prevents crash when called on a file
-14. **MediaBrowser redesign** — file click = `onSelect` + close; folder click = navigate; per-row kebab (`MoreVert`) opens a Dialog with contextual actions; permanent "Select Folder" button in footer; no mode-toggle buttons
+14. **MediaBrowser redesign** — file click = `onSelect` + close; folder click = navigate; per-row kebab (`MoreVert`) opens a Dialog with contextual actions; permanent "Select Folder" button in footer
 15. **Settings persistence** — `settings.ts` + `useSettings()` hook: loads `/.sys/config.json` via WebDAV on mount, auto-saves 3 s after last change, exposes `saveStatus` / `pendingCount` / `flushNow`; `beforeunload` flushes via `fetch keepalive`
 16. **Save-status badge** — `SaveStatusBadge` in `App.tsx` header shows: idle (hidden), loading spinner, amber "N unsaved + Save button", saving spinner, saved checkmark, red error + retry
+17. **File icons by extension** — MediaManager shows `Disc` icon for disk extensions (`.d64`, `.d71`, `.d81`, etc.) and `HardDrive` icon for HD extensions (`.img`, `.iso`, etc.)
+18. **Device URL display** — StatusPage shows `device.base_url + device.url` concatenated
+19. **WebSocket server** — `webdav3.py` upgraded with RFC 6455 WebSocket handler at `/ws`; echoes received frames to all connected clients; thread-safe broadcast
+20. **RealityOverridePage** — full-screen page that subscribes to WS commands and displays them centered on screen; Three.js Digital Tokamak vortex background with `UnrealBloomPass`; twinkling star field canvas always running beneath
+21. **RealityOverrideAdminPage** — command palette (Image/Audio/Video conversion groups, 30 commands); freeform command input with Enter key support; sent-command flash indicator
+22. **Source map warnings fixed** — stripped all `//# sourceMappingURL=` comments from 26 vendored webdav-component ESM files
+23. **MediaManager: navigate into new folder** — after `handleCreateFolder`, automatically calls `load(newPath)` to navigate into the created folder
+24. **MediaManager: Configure Folder** — "Configure Folder" action in kebab menu creates `.config` if absent and opens it in ConfigEditor; saving re-parses content into `folderConfig` state immediately and closes editor
+25. **Mount logic: base_url=`.`** — in `.config`, `base_url: .` resolves to the current folder path; mounting a file inside the base sets `url` to the relative path; mounting outside clears `base_url`
+26. **Media Set existence check** — `Promise.all(fileExists)` filter applied before building media set in both MediaManager and DeviceDetailOverlay; toast warning shown if some files are missing
+27. **Mobile PWA fullscreen** — `viewport-fit=cover`, `apple-mobile-web-app-capable`, `black-translucent` status bar style, `apple-mobile-web-app-title`; body `overscroll-behavior: none`; safe-area CSS env() insets on header and nav
+28. **Fullscreen API button** — header Maximize2/Minimize2 button; webkit prefix fallback; `isFullscreen` state tracks `fullscreenchange` event
+29. **Logo click → status page** — logo wrapped in `<button onClick={() => setCurrentPage('status')}>`
+30. **Double-tap to toggle vortex** — `onPointerDown` handler with `isPrimary` guard and 400 ms window; `pausedRef` + `bgVisible` state; mode persisted in `localStorage` key `ro-bg`
+31. **Shared WebSocket context** — `ws.tsx`: `WsProvider` manages a single `WebSocket` to `ws://<hostname>/ws`; subscriber pattern via `listeners` ref Set; auto-reconnect after 3 s; `useWs()` exposes `{ status, send, subscribe }`; `App.tsx` return wrapped in `<WsProvider>`
+32. **Components migrated to shared WS** — `RealityOverridePage` and `RealityOverrideAdminPage` removed own WS effects; now use `useWs()`; status indicator uses `Radio` icon (distinct from `Wifi` used for WiFi)
+33. **StatusPage WS status** — `Radio` icon + live `wsStatus` shown in System Status grid alongside WiFi
+34. **Reset via WebSocket** — "Reset Meatloaf" sends `"reset"`; "Reset Host" sends `"reset hard"` via shared WS on confirm
+35. **Rescan Bus via WebSocket** — DevicesPage "Rescan Bus" button sends `"iec scan"` via shared WS
+36. **WiFi Scan via WebSocket** — NetworkPage "Scan" button sends `"scan"` via shared WS before opening overlay
+37. **WiFi connect via WebSocket** — WiFiScanOverlay "Connect" sends `"connect <ssid>"` or `"connect <ssid> <password>"`; NetworkPage known-network click sends same command, marks network `enabled: 1`, moves it to top of list
+38. **Split config / devices storage** — `settings.ts` loads `/.sys/config.json` and `/.sys/devices.json` in parallel; merges with one-level deep merge (so `iec.devices` from devices.json is merged into `iec` from config.json); saves with split: `iec.devices` → `devices.json`, everything else (including remaining `iec` bus settings) → `config.json`; `beforeunload` flush also split across both files
 
 ## Known Issues / Open Work
 
 - **Service worker 404**: `https://meatloaf.cc/service-worker.js` returns 404. The SW is not being served at the correct path relative to the `/config/` base.
-- **App pages**: All individual app pages (Directory Editor, Sector Editor, etc.) are stubs. Actual implementations are pending.
+- **App pages**: Most individual app pages are stubs. Reality Override and Override Admin are implemented; all others show "coming soon".
+- **WiFi scan results**: Currently mock data. Needs real scan results delivered over WebSocket from the device.
+- **Reset confirmation**: The "in-progress" and "done" states are simulated with `setTimeout`. Needs real completion signal from the device over WebSocket.
 
 ## Configuration Shape
 
-Config is stored at `files/.sys/config.json` on the device and loaded at runtime via WebDAV. Top-level keys: `general`, `host`, `hardware`, `wifi`, `network`, `bluetooth`, `modem`, `cassette`, `iec`, `boip`. The `useSettings()` hook in `settings.ts` provides `config` / `setConfig` to all page components (passed as props from `App.tsx`).
+Config is split across two files on the device:
+
+| File | Contents |
+|---|---|
+| `/.sys/config.json` | `general`, `host`, `hardware`, `wifi`, `network`, `bluetooth`, `modem`, `cassette`, `boip`, `iec` (bus settings only — no `iec.devices`) |
+| `/.sys/devices.json` | `{ "iec": { "devices": { "printer": {...}, "drive": {...}, "network": {...}, "other": {...}, "meatloaf": {...} } } }` |
+
+The `useSettings()` hook in `settings.ts` loads both files on mount, merges them into a single `config` object, and splits them back on save. All page components receive the unified `config` / `setConfig` props from `App.tsx`.
+
+The bundled `src/imports/config.json` is used as the initial UI state while the server fetch is in flight. It contains the full merged shape (including `iec.devices`) so the UI renders immediately without waiting.
+
+## WebSocket Layer
+
+A single `WebSocket` connection to `ws://<hostname>/ws` is managed by `WsProvider` in `ws.tsx` and shared app-wide via React Context.
+
+| Export | Purpose |
+|---|---|
+| `WsProvider` | Mounts in `App.tsx`; owns connection lifecycle + auto-reconnect |
+| `useWs()` | Returns `{ status: WsStatus, send, subscribe }` |
+| `WsStatus` | `'connecting' \| 'connected' \| 'disconnected'` |
+| `send(msg)` | Sends a string frame if socket is open |
+| `subscribe(handler)` | Adds a message listener; returns unsubscribe function |
+
+Commands sent to the device:
+
+| Command | Sent from | Trigger |
+|---|---|---|
+| `reset` | StatusPage | Reset Meatloaf confirmed |
+| `reset hard` | StatusPage | Reset Host confirmed |
+| `iec scan` | DevicesPage | Rescan Bus button |
+| `scan` | NetworkPage | WiFi Scan button |
+| `connect <ssid> [<pass>]` | NetworkPage / WiFiScanOverlay | Network tap / Connect button |

+## Architecture Highlights
+
+### Shared WebSocket
+A single `WebSocket` connection to `ws://<device-hostname>/ws` is managed by `WsProvider` (`src/app/ws.tsx`) and shared app-wide via React Context. Any component can send commands or subscribe to incoming frames via `useWs()`. The connection auto-reconnects every 3 s on drop.
+
+### Split Config Storage
+Device settings are stored in two separate files on the device (LittleFS erase-block friendly, ≤ 4 096 bytes each):
+
+| File | Contents |
+|---|---|
+| `/.sys/config.json` | General, host, hardware, WiFi, network, Bluetooth, modem, cassette, BOIP, IEC bus settings |
+| `/.sys/devices.json` | IEC device list (`iec.devices`) |
+
+`useSettings()` loads both files in parallel and merges them; saves split them back automatically. A bundled fallback (`src/imports/config.json`) is used as the initial UI state while the device is being contacted.
+
+### WebDAV Layer
+All file I/O goes through `src/app/webdav.ts`, which wraps the vendored `webdav-component` (browser-native `fetch` + `DOMParser`, no npm dependencies).
