Public routes cover marketing, legal pages, login, sources, and shared content. `/app/*` routes pass through `RequireAuth` and include the main tools, the Current Debate dashboard (`/app/debate`), history, library, timer, sparring, flowchart, settings, and administration. The header holds only Home, the Current debate menu, Library, History, and the language, theme, and Settings controls; tools are launched from Home and the dashboard.
 
 `AuthProvider`, TanStack Query, theme and motion providers, toast systems, the offline indicator, and the route error boundary wrap the routed application.
 
 ## Client state
 
 [`src/lib/stores/session-store.ts`](../src/lib/stores/session-store.ts) owns active AI results, conversations, saved work, sources, folders, flowcharts, autosave state, and persisted form state. It persists selected local state and hydrates authenticated rows from Supabase.
 
+[`src/lib/stores/debate-store.ts`](../src/lib/stores/debate-store.ts) owns the signed-in user's debates, the Current Debate pointer, session-only one-off mode, and the shared Switch and Start dialogs. Every source and every automatically recorded result carries a `debateId`; one-off work and unsorted legacy rows have none. The Library, History, the AI source context, and discovered-source autosave all read from one debate at a time, so material never crosses debates. Motion-bearing tools confirm a motion that differs from the Current Debate (switch, create, or use once) before submitting, and the app blocks with Continue, Start new, or Switch after five days without work in the Current Debate.

 [`src/lib/stores/settings-store.ts`](../src/lib/stores/settings-store.ts) owns language, theme, feature provider settings, prompts, and research preferences. It persists locally and synchronizes authenticated settings.
 
 [`src/lib/stores/sparring-store.ts`](../src/lib/stores/sparring-store.ts) owns active sparring rounds in session storage and hydrates completed sessions from Supabase.

-Authenticated personal AI requests carry stable source IDs instead of source content. The Edge Function loads matching active rows for the authenticated user, bounds their title, content, origin, and type, then passes that context to ranking and prompt construction. Jev scores relevance, importance, and evidence strength after the existing deterministic quality floor, while failures preserve the prior order. Generate also records a bounded source-use snapshot in the saved case output. Semantic counts and the latest case-use flag live in the existing source `metadata` JSON, so the Library can default to Smart ordering without a schema migration.
