 - `sources.ts` mirrors the session store's `addSource` and `removeSource` and `src/lib/source-import.ts`. The Library always shows the Current Debate, also in one-off mode, as on the website. Adding a file (the website parses files in the browser) and Scan pages are not in the app yet.
 - Ask mirrors `src/lib/ai/streaming.ts` and `askChat` in `src/lib/ai/client.ts`: `ask.ts` sends the requests (plain questions stream from `ai-stream` through `expo/fetch`; with Citations, Web search, Pros/Cons or Argument map on, the whole answer comes from `ai`, because `ai-stream` refuses those options), `ai-request.ts` holds the shared POST with the website's headers, timeout and error kinds, `feature-config.ts` reads each tool's model from `user_settings.feature_configs`, `context-request.ts` builds the Current Debate context with the website's default selection and pins, and `chats.ts` saves finished exchanges to `chats` and `messages`. The SSE parser is shared in `packages/core/src/ai/sse.ts`. `markdown.ts` reads answers, because react-markdown needs the DOM.
 - Generate and Attack mirror `generateCase` and `attackCase` in `src/lib/ai/client.ts` and the session store's `recordResult`: `results.ts` sends the requests through `ai-request.ts`, checks the output with the website's transform (moved to `packages/core/src/ai/generate-output.ts`), keeps researched sources in the debate's Auto-saved folder (`packages/core/src/ai/discovered-sources.ts`), saves the server's source rankings onto the Library sources a result used (`packages/core/src/ai/source-assessments.ts`, also for Ask's whole answers), says when the server shortened the input, and saves rows to `cases` and `attacks`. `motion.ts` and `motion-gate.ts` are the website's motion gate. `open-results.ts` holds results made in this session, so one-off work and failed saves still open as documents. It and the last Generate and Attack forms live in `session-memory.ts`, which the auth provider clears on every account change, including sign-out. `components/document.tsx` draws results as documents (mock 03); Brainstorm and Factoids reuse it. Export renders `export-html.ts` to a PDF with expo-print and shares it (`export.ts`); the web preview cannot print, so `export.web.ts` keeps the HTML and copied text on `window` for the screenshot script. Word export and Google Docs are not in the app.
-- One-off mode is session-only and never written, as on the website. The switcher turns it on with or without a Current Debate, and `OneOffNotice` shows it on the Debate tab, Ask and Library. Students prepare both sides of a motion, so a debate has no side: the Debate tab's In favor / Against toggle only chooses which side's work it shows, using the website's rule (`'both'` counts for either side, neutral and side-less work for neither). It starts on In favor and is never stored.
+- One-off mode is session-only and never written, as on the website. The switcher turns it on with or without a Current Debate, and `OneOffNotice` shows it on the Debate tab, Prepare, Ask, Library, Generate and Attack (through `WorkingIn`).

 - `src/theme/`: colours from the mocks and the website's dark palette, Inter fonts.
 - `scripts/screenshots.ts`: web-export screenshots. `scripts/render-tab-icons.ts` redraws the tab bar PNGs.
