* feat(app): preview HTML files in the file pane Renders .html/.htm files as a page in the file pane, with the same Preview/Source toggle Markdown already has. The main use is reading richer visual plans an agent wrote as a self-contained HTML page. A preview is a viewer, not a browser. Each document is prefixed with a doctype and a strict policy, so the policy is always the first element and always lands in the parser-created head: inline script and style run, and remote subresources, fetch, XHR, WebSocket, beacon, and form posts are refused. The frame has an opaque origin, so it cannot reach the app's DOM and storage and cookie APIs throw inside it. One gap is left on web and cannot be closed there: a sandboxed document may navigate itself, and no CSP directive in current browsers prevents it -- navigate-to was dropped from CSP3 and is unenforced, and meta refresh needs no script (both verified against the Chromium the app ships against). The opaque origin bounds it to the page's own contents, and SECURITY.md documents it. Native narrows it further by refusing navigation after the initial document, with the caveat that the decision runs in app JS. Self-contained pages only -- a page that pulls a CDN script renders unstyled, and Source still shows everything. * fix(app): harden HTML preview behavior and tests --------- Co-authored-by: Nicholas Salgueiro <nicholas.salgueiro@britecore.com> Co-authored-by: Mohamed Boudra <boudra.moha@gmail.com>
Welcome to your Expo app 👋
This is an Expo project created with create-expo-app.
Get started
-
Install dependencies
npm install -
Start the app
npx expo start
In the output, you'll find options to open the app in a
- development build
- Android emulator
- iOS simulator
- Expo Go, a limited sandbox for trying out app development with Expo
You can start developing by editing the files inside the app directory. This project uses file-based routing.
Get a fresh project
When you're ready, run:
npm run reset-project
This command will move the starter code to the app-example directory and create a blank app directory where you can start developing.

Dictation debugging
Set EXPO_PUBLIC_ENABLE_AUDIO_DEBUG=1 before running npx expo start to render the in-app audio debug card. Pair it with the server-side STT_DEBUG_AUDIO_DIR flag so every dictation includes a copyable path to the saved raw audio file.
