 ## Layout
 
-- `src/app/`: routes. `sign-in.tsx`; `(tabs)/` with one route group per tab: Debate, Prepare, Practice, Library, You; the form sheets `debates.tsx` (switcher), `new-debate.tsx`, `delete-account.tsx`, `add-link.tsx`, `new-note.tsx` and `source/[id].tsx`; and `ask.tsx`, `generate.tsx`, `case/[id].tsx`, `attack/index.tsx` and `attack/[id].tsx`, full screen above the tabs. All are declared in the root `_layout.tsx`. `(prepare)/coming/[tool].tsx` and `(practice)/soon/[tool].tsx` stand in for tools not in the app yet.
+- `src/app/`: routes. `sign-in.tsx`; `(tabs)/` with one route group per tab: Debate, Prepare, Practice, Library, You; the form sheets `debates.tsx` (switcher), `new-debate.tsx`, `delete-account.tsx`, `add-link.tsx`, `new-note.tsx` and `source/[id].tsx`; and `ask.tsx`, `generate.tsx`, `case/[id].tsx`, `attack/`, `brainstorm/` and `factoids/` (each a form `index.tsx` and a document `[id].tsx`), full screen above the tabs. All are declared in the root `_layout.tsx`. `(prepare)/coming/[tool].tsx` (Flowchart) and `(practice)/soon/[tool].tsx` stand in for tools not in the app yet.
 - `src/components/`: shared UI. `app-tabs.tsx` uses native tabs; `app-tabs.web.tsx` draws the mock's tab bar for the web preview.
 - `src/lib/`: auth (`auth.tsx`), the Supabase client, session storage (AES key in SecureStore, ciphertext in AsyncStorage) and i18n. `debates.ts`, `settings.tsx`, `subscription.ts` and `account.ts` read and write the website's tables the way its stores do (`src/lib/stores/debate-store.ts`, `settings-store.ts`, `src/hooks/use-subscription.ts`, `src/lib/account.ts`), so the app and the website share one Current Debate and one set of settings. Change them together with the website code they mirror.
 - `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, Prepare, Ask, Library, Generate and Attack (through `WorkingIn`). The Debate tab, Prepare and Library still list the Current Debate's work in one-off mode, as the website's home does. 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.
+- Brainstorm and Factoids mirror `brainstorm` and `factoids` in `src/lib/ai/client.ts` and their pages, through the same `results.ts`: the brainstorm transform and the verified-factoid selection live in `packages/core/src/ai/brainstorm-output.ts` and `factoids-output.ts`, rows go to `brainstorms` and `factoids`. Brainstorm has the motion gate; Factoids, like Attack, follows the Current Debate and saves with side `neutral`. A factoid's bookmark saves it to the Current Debate's `Factoids` folder, and a search suggestion reopens the Factoids form with that query. `prepareToolHref` in `components/prepare-tools.ts` is where both tabs open a tool.
+- 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 and the Generate, Attack, Brainstorm and Factoids forms (through `WorkingIn`). The Debate tab, Prepare and Library still list the Current Debate's work in one-off mode, as the website's home does. 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.
 - `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.
