-# Ranked EQAO — Claude Code Guide
-
-## Project Overview
-A ranked quiz app based on EQAO (Ontario standardized tests).
-Users sign in with Google, answer questions by grade and subject,
-and compete on leaderboards.
-
-## Tech Stack
-- **Runtime:** Node.js + Express
-- **Database:** PostgreSQL via Prisma ORM
-- **Auth:** Google OAuth 2.0 (Passport.js) + JWT
-- **AI:** Gemini API (passage + question generation for English; answer checking)
-- **Frontend:** React (Vite) — `frontend/` directory
-
-## Grades
-Only three grades are supported: **3, 6, 9**
-- In the schema these are the `Grade` enum: `G3`, `G6`, `G9`
-- Never use raw integers for grade — always use the enum
-
-## Subjects
-Two sections per quiz: `MATH` and `ENGLISH` (reading + writing combined)
-- The Prisma `Subject` enum currently has `MATH`, `READING`, `WRITING` — these remain as-is for DB storage
-- In the UI and game logic, treat READING + WRITING as a single **English** section

-## Environment Variables
-| Variable | Purpose |
-|---|---|
-| `DATABASE_URL` | PostgreSQL connection string |
-| `GOOGLE_CLIENT_ID` | Google OAuth app client ID |
-| `GOOGLE_CLIENT_SECRET` | Google OAuth app client secret |
-| `GOOGLE_CALLBACK_URL` | OAuth redirect URI |
-| `JWT_SECRET` | Secret for signing JWTs |
-| `GEMINI_API_KEY` | Gemini API key for English question/passage generation and answer checking |
-| `PORT` | Express server port (default 3000) |
-| `FRONTEND_URL` | Frontend origin for CORS |
-
-## Key Conventions
-- Always use `Grade` enum (`G3`, `G6`, `G9`) — never raw numbers
-- Always use `Subject` enum (`MATH`, `READING`, `WRITING`)
-- All routes that touch user data require the `auth.js` JWT middleware
-- Leaderboard is scoped per `[userId, grade, subject]` — unique constraint enforced in DB
-- Sessions track full answer history via `UserAnswer` for future analytics
-
-## Database Commands
-```bash
-npx prisma migrate dev --name <migration_name>   # new migration
-npx prisma generate                               # regenerate client after schema change
-npx prisma studio                                 # visual DB browser
-```

-## Frontend Pages
-
-### Login.jsx (Pre-login Landing Page) — KEEP, DO NOT ADD DEBUG BUTTON
-- The current pre-login landing page and Google sign-in button are good — preserve this design
-- The page will eventually be a longer scrollable page with a top navigation bar linking to info sections and other useful tabs (TBD before release)
-- **DO NOT add any debug/bypass button that skips Google login** — all such buttons must be removed if found anywhere in the codebase
-- For now, leave the landing page as-is; extended layout/nav is a pre-release task
-
-### MathGame.jsx — SCRAPPED, DELETE THIS FILE
-- `frontend/src/pages/MathGame.jsx` is fully scrapped — delete it
-- Remove all routes, imports, and links pointing to MathGame anywhere in the codebase
-- The actual EQAO quiz experience will be built fresh (see Quiz UI section below)
-
-### Dashboard.jsx (Post-login) — TO BE BUILT
-- Replaces the current "Coming Soon" placeholder
-- Should be a rich, well-designed dashboard with multiple sections/widgets, for example:
-  - User greeting with avatar
-  - Stats summary (games played, best scores, rank per grade)
-  - Leaderboard preview
-  - Recent activity
-  - A **"Start Game"** button (prominent CTA) — the button exists in the UI but does NOT wire up to the quiz yet; the quiz flow is not being programmed at this stage
-- The exact set of dashboard widgets/tabs is TBD — design it to look complete and polished even if most data is placeholder
-
----
-
-## Quiz UI (To Be Built — Design Reference)
-
-### General Flow
-The quiz covers **two sections**: Math and English. The user completes them in order.
-
-After finishing a section, the app checks answers and shows one of two outcomes:
-- **100% correct** → proceed to the next section (or end the quiz if both are done)
-- **At least 1 wrong** → must redo the section; keep retrying until 100% correct before advancing
-
-There is no partial credit / moving on with mistakes — the player must get a perfect section to continue.
-
-### Math Section
-- Questions are **pre-generated** (not from Gemini) but with **randomised values each time** so the same question template produces different numbers on each attempt
-- Questions should be creative and contextual — avoid trivial `a + b` style arithmetic; think word problems, patterns, multi-step reasoning appropriate to the grade level
-- Multiple choice format (matching the original EQAO UI style — see design reference below)
-
-### English Section
-- **Gemini API** generates a reading passage appropriate for the grade
-- Gemini also generates comprehension questions based on that passage
-- Gemini checks free-response and paragraph writing answers (not just multiple choice)
-- The section combines reading comprehension and a short writing component
-
-### Quiz UI Design
-- The actual in-quiz UI (question display, answer choices, progress) should stay **visually identical or very close to the original MathGame design** — same layout, card style, fonts, colour scheme
-- Reference the existing `index.css` (`.math-game`, `.choice-btn`, `.grade-btn`, etc.) and replicate that look for the new quiz component
-- Upload of reference screenshots is pending — when provided, match them closely
-
----
-
-## What's Not Built Yet
-- [ ] API routes (auth, sessions, leaderboard, questions)
-- [ ] Gemini service for English passage + question generation and answer checking
-- [BUILT] Math question templates with randomised values
-- [BUILT] Quiz game component (replaces scrapped MathGame.jsx)
-- [HALF-BUILT] Post-login Dashboard (rich version, not "Coming Soon" placeholder)
-- [HALF-BUILT] Pre-login landing page extended layout + top nav (pre-release)
-- [ ] Question seeding/storage strategy
-- [ ] Frontend wiring for "Start Game" button
