# Platform Admin Dashboard

Product-agnostic admin console for the ByteLyst platform. Connects **directly** to Azure Cosmos DB via the `@azure/cosmos` SDK — no intermediate API server. Set `PRODUCT_ID` in `.env.local` to deploy for any product (e.g. `lysnrai`, `chronomind`, `nomgap`, `mindlyst`).

## Cosmos DB Integration

The dashboard connects **directly** to Cosmos DB — no intermediate backend server.

**Pattern:**

```
Page Component → fetch("/api/...") → API Route → Repository → Cosmos SDK → Azure
```

**Key files:**

- `lib/cosmos.ts` — singleton `CosmosClient`, `getContainer(name)`, `initializeAllContainers()`
- `lib/repositories/*.ts` — CRUD functions per container
- `lib/auth-server.ts` — `authenticateUser()`, `createAccessToken()`, `verifyToken()`

**Container definitions** (in `cosmos.ts`):

| Container     | Partition Key | TTL     |
| ------------- | ------------- | ------- |
| `users`       | `/id`         | —       |
| `licenses`    | `/userId`     | —       |
| `transcripts` | `/userId`     | —       |
| `usage_daily` | `/userId`     | 1 year  |
| `settings`    | `/userId`     | —       |
| `audit_log`   | `/category`   | 90 days |
| `api_tokens`  | `/userId`     | —       |
| `devices`     | `/userId`     | —       |

## Kill Switch

The Settings page has a prominent kill switch card at the top:

- **Green** = platform active, **Red** = platform disabled
- Toggle writes to `settings` container: `{ id: "kill_switch", userId: "system", enabled: bool }`
- All apps (desktop, mobile, web) read this document to check platform status

## Features

- **Direct Cosmos DB** — no middleware, API routes call SDK directly
- **JWT auth** — bcrypt password hashing, HS256 JWT tokens
- **Auth guard** — redirects to `/login` if not authenticated
- **Mock fallback** — pages fall back to mock data if Cosmos is unavailable
- **Responsive** — sidebar collapses to hamburger on mobile
- **Dark mode** — toggle in sidebar footer, persisted to localStorage
- **Error boundary** — catches page crashes gracefully
- **Kill switch** — global platform toggle on Settings page

## Docker

```bash
docker build -t platform-admin .
docker run -p 3001:3000 --env-file .env.local platform-admin

# Or with docker-compose
docker compose up -d
```

## Development Notes

- **Port**: runs on 3001 in dev (3000 may conflict with Docker)
- **shadcn/ui**: components are in `src/components/ui/`, added via `npx shadcn@latest add <component>`
- **Adding a new API route**: create `src/app/api/<name>/route.ts`, import from `@/lib/repositories/*`
- **Adding a new page**: create `src/app/(dashboard)/<name>/page.tsx` — auto-protected by auth guard
