-# Copilot Instructions – Bluelearn
-
-## Project Overview
-Bluelearn is an open‑source, prerequisite‑graph education platform built as a pnpm monorepo with:
-- **Frontend (app/)**: React 19, TanStack Start (SSR), TanStack Router, Tailwind CSS v4, shadcn/ui
-- **API (api/)**: Hono on Cloudflare Workers, TypeScript, Supabase for auth/data
-- **Database (supabase/)**: PostgreSQL with Row‑Level Security (RLS), migrations
-
-## Development Workflow
-1. **Prerequisites**: Docker, Node.js ≥20, pnpm ≥10.33.1, Supabase CLI
-2. **Setup**:
-   - `pnpm install`
-   - `pnpm supabase:start` (requires Docker)
-   - Copy `app/.env.example` → `.env` and `api/.dev.vars.example` → `.dev.vars`
-   - Fill environment variables from `supabase status`
-   - `pnpm dev:api` then `pnpm dev:app`
-3. **Common Commands** (run from root):
-   - `pnpm dev` – start both frontend and API
-   - `pnpm build` – build all packages
-   - `pnpm typecheck` – TypeScript check across workspace
-   - `pnpm lint` – ESLint
-   - `pnpm format` – Prettier (with Tailwind plugin)
-   - `pnpm test` – Vitest tests (frontend only)
-   - `pnpm supabase:reset` – reset database
-
-## Architectural Constraints
-- **Frontend never calls Supabase directly** – all data flows through the API.
-- **API is stateless** – state lives in Postgres, cached state will use Workers KV later.
-- **Authentication**: Supabase JWTs sent in `Authorization` header, verified by `supabaseMiddleware`.
-- **RLS** does access control; API uses per‑request Supabase client with user's token.
-- **Database types** are generated: `supabase gen types typescript --local > api/src/database.types.ts`
-
-## Code Conventions
-- **Frontend routing**: File‑based (TanStack Router) in `app/src/routes/`.
-- **Styling**: Tailwind CSS, use `cn()` from `app/src/lib/utils.ts` for conditional classes.
-- **Components**: shadcn/ui primitives in `app/src/components/ui/`. Add via `npx shadcn@latest add`.
-- **API routes**: Each resource has its own Hono router in `api/src/routes/`. Use `@hono/zod‑validator` for validation.
-- **Migrations**: Timestamp‑prefixed `.sql` files in `supabase/migrations/`. Apply with `supabase db reset` or `supabase db push`.
-- **Type safety**: API exports `AppType` (from `api/src/index.ts`) for end‑to‑end type‑safe calls (not yet wired).
-
-## Environment Variables
-- **Frontend** (`app/.env`): `VITE_SUPABASE_URL`, `VITE_SUPABASE_PUBLISHABLE_KEY`, `VITE_API_BASE`
-- **API** (`api/.dev.vars`): `SUPABASE_URL`, `SUPABASE_PUBLISHABLE_KEY`, `SUPABASE_SECRET_KEY`, `APP_URL`
-- **Production**: API variables become Cloudflare Workers secrets.
-
-## Feature Development Sequence
-1. **Database**: Create migration → apply → regenerate types.
-2. **API**: Add route with validation → mount in `index.ts`.
-3. **Frontend**: Create/update route → fetch data (typed client when available) → UI with shadcn.
-4. **Validation**: Run `pnpm typecheck`, `pnpm lint`, `pnpm format`.
-5. **Testing**: Add Vitest tests for frontend components.
-
-## Gotchas
-- Docker must be running for `supabase start`.
-- Environment variables differ between app (VITE_ prefix) and API (plain).
-- CORS allows only `APP_URL` (set in `.dev.vars`).
-- `api/src/database.types.ts` is a stub; regenerate after schema changes.
-- Only `profiles` table exists currently; full schema described in `docs/database‑schema.md`.
