-# Express.js API Server Plan
-
-## Goal
-Add an Express.js backend server to handle API routes (starting with Claude API), with support for either combined or split deployment.
-
-## Advantages Over Next.js Migration
-- **Minimal frontend changes** - only API URL configuration
-- **No routing changes** - keep react-router-dom as-is
-- **Flexible deployment** - combined or split frontend/backend
-- **Already partially exists** - `server.js` in root has Express + vite-express scaffolding
-
-## Deployment Options
-
-### Option A: Combined (Single Server)
-```
-Express Server (vite-express)
-├── Serves static files from dist/
-└── Handles /api/* routes
-```
-- Simpler setup, one deployment
-- Good for: VPS, Railway, Fly.io, DigitalOcean App Platform
-
-### Option B: Split (Separate Hosts)
-```
-Static Host (CDN)              API Server (Node.js)
-├── Cloudflare Pages           ├── Railway
-├── Netlify                    ├── Fly.io
-├── Vercel                     ├── AWS Lambda
-└── S3 + CloudFront            └── Any VPS
-
-Serves dist/                   Handles /api/*
-```
-- Better scalability, cheaper static hosting
-- Good for: High traffic, global CDN distribution
-
----
-
-## Current State
-
-### Existing `server.js` (incomplete)
-```javascript
-import express from "express";
-import ViteExpress from "vite-express";
-import dotenv from "dotenv";
-import expressProxy from "express-http-proxy";
-
-dotenv.config();
-const app = express();
-app.use("/api", expressProxy("local.immersiveidea.com"));
-ViteExpress.listen(app, process.env.PORT || 3001, () => console.log("Server is listening..."));
-```
-
-### Missing Dependencies
-The following packages are imported but not in package.json:
-- `express`
-- `vite-express`
-- `express-http-proxy`
-- `dotenv`
-
----
-
-## Implementation Plan
-
-### Phase 1: Install Dependencies
-
-```bash
-npm install express vite-express dotenv cors
-```
-
-- `express` - Web framework
-- `vite-express` - Vite integration for combined deployment
-- `dotenv` - Environment variable loading
-- `cors` - Cross-origin support for split deployment
-
-### Phase 2: Create API Routes Structure
-
-Create a modular API structure:
-
-```
-server/
-├── server.js              # Existing WebSocket server (keep as-is)
-├── api/
-│   ├── index.js           # Main API router
-│   └── claude.js          # Claude API proxy route
-```
-
-### Phase 3: Update Root `server.js`
-
-Replace the current incomplete server.js with:
-
-```javascript
-import express from "express";
-import ViteExpress from "vite-express";
-import cors from "cors";
-import dotenv from "dotenv";
-import apiRoutes from "./server/api/index.js";
-
-dotenv.config();
-
-const app = express();
-
-// CORS configuration for split deployment
-// In combined mode, same-origin requests don't need CORS
-const allowedOrigins = process.env.ALLOWED_ORIGINS?.split(",") || [];
-if (allowedOrigins.length > 0) {
-  app.use(cors({
-    origin: allowedOrigins,
-    credentials: true,
-  }));
-}
-
-app.use(express.json());
-
-// API routes
-app.use("/api", apiRoutes);
-
-// Check if running in API-only mode (split deployment)
-const apiOnly = process.env.API_ONLY === "true";
-
-if (apiOnly) {
-  // API-only mode: no static file serving
-  app.listen(process.env.PORT || 3000, () => {
-    console.log(`API server running on port ${process.env.PORT || 3000}`);
-  });
-} else {
-  // Combined mode: Vite handles static files + SPA
-  ViteExpress.listen(app, process.env.PORT || 3001, () => {
-    console.log(`Server running on port ${process.env.PORT || 3001}`);
-  });
-}
-```
-
-### Phase 4: Create API Router
-
-**`server/api/index.js`**:
-```javascript
-import { Router } from "express";
-import claudeRouter from "./claude.js";
-
-const router = Router();
-
-// Claude API proxy
-router.use("/claude", claudeRouter);
-
-// Health check
-router.get("/health", (req, res) => {
-  res.json({ status: "ok" });
-});
-
-export default router;
-```
-
-**`server/api/claude.js`**:
-```javascript
-import { Router } from "express";
-
-const router = Router();
-const ANTHROPIC_API_URL = "https://api.anthropic.com";
-
-router.post("/*", async (req, res) => {
-  const apiKey = process.env.ANTHROPIC_API_KEY;
-
-  if (!apiKey) {
-    return res.status(500).json({ error: "API key not configured" });
-  }
-
-  // Get the path after /api/claude (e.g., /v1/messages)
-  const path = req.params[0] || req.path;
-
-  try {
-    const response = await fetch(`${ANTHROPIC_API_URL}${path}`, {
-      method: "POST",
-      headers: {
-        "Content-Type": "application/json",
-        "x-api-key": apiKey,
-        "anthropic-version": "2023-06-01",
-      },
-      body: JSON.stringify(req.body),
-    });
-
-    const data = await response.json();
-    res.status(response.status).json(data);
-  } catch (error) {
-    console.error("Claude API error:", error);
-    res.status(500).json({ error: "Failed to proxy request to Claude API" });
-  }
-});
-
-export default router;
-```
-
-### Phase 5: Update Vite Config
-
-Remove the Claude proxy from `vite.config.ts` since Express handles it now.
-
-**Before** (lines 41-56):
-```javascript
-'^/api/claude': {
-    target: 'https://api.anthropic.com',
-    changeOrigin: true,
-    rewrite: (path) => path.replace(/^\/api\/claude/, ''),
-    configure: (proxy) => {
-        proxy.on('proxyReq', (proxyReq) => {
-            const apiKey = env.ANTHROPIC_API_KEY;
-            // ...
-        });
-    }
-}
-```
-
-**After**: Remove this block entirely. The Express server handles `/api/claude/*`.
-
-Keep the other proxies (`/sync/*`, `/create-db`, `/api/images`) - they still proxy to deepdiagram.com in dev mode.
-
-### Phase 6: Add API URL Configuration (for Split Deployment)
-
-Create a utility to get the API base URL:
-
-**`src/util/apiConfig.ts`**:
-```typescript
-// API base URL - empty string for same-origin (combined deployment)
-// Set VITE_API_URL for split deployment (e.g., "https://api.yourdomain.com")
-export const API_BASE_URL = import.meta.env.VITE_API_URL || '';
-
-export function apiUrl(path: string): string {
-  return `${API_BASE_URL}${path}`;
-}
-```
-
-**Update `src/react/services/diagramAI.ts`**:
-```typescript
-import { apiUrl } from '../../util/apiConfig';
-
-// Change from:
-const response = await fetch('/api/claude/v1/messages', { ... });
-
-// To:
-const response = await fetch(apiUrl('/api/claude/v1/messages'), { ... });
-```
-
-This change is backward-compatible:
-- **Combined deployment**: `VITE_API_URL` is empty, calls go to same origin
-- **Split deployment**: `VITE_API_URL=https://api.example.com`, calls go to API server
-
-### Phase 7: Update package.json Scripts
-
-```json
-"scripts": {
-  "dev": "node server.js",
-  "build": "node versionBump.js && vite build",
-  "start": "NODE_ENV=production node server.js",
-  "start:api": "API_ONLY=true node server.js",
-  "test": "vitest",
-  "socket": "node server/server.js",
-  "serverBuild": "cd server && tsc"
-}
-```
-
-**Changes:**
-- `dev`: Runs Express + vite-express (serves Vite in dev mode)
-- `start`: Combined mode - serves dist/ + API
-- `start:api`: API-only mode for split deployment
-- Removed `preview` (use `start` instead)
-
----
-
-## File Changes Summary
-
-| Action | File | Description |
-|--------|------|-------------|
-| Modify | `package.json` | Add dependencies, update scripts |
-| Modify | `server.js` | Full Express server with CORS + API routes |
-| Create | `server/api/index.js` | Main API router |
-| Create | `server/api/claude.js` | Claude API proxy endpoint |
-| Create | `src/util/apiConfig.ts` | API URL configuration utility |
-| Modify | `src/react/services/diagramAI.ts` | Use apiUrl() for API calls |
-| Modify | `vite.config.ts` | Remove `/api/claude` proxy block |
-
----
-
-## How vite-express Works
-
-`vite-express` is a simple integration that:
-
-1. **Development**: Runs Vite's dev server as middleware, providing HMR
-2. **Production**: Serves the built `dist/` folder as static files
-
-This means:
-- One server handles both API and frontend
-- No CORS issues (same origin)
-- HMR works in development
-- Production-ready with `vite build`
-
----
-
-## Production Deployment
-
-### Option A: Combined Deployment
-
-Single server handles both frontend and API:
-
-```bash
-# Build frontend
-npm run build
-
-# Start combined server (serves dist/ + API)
-npm run start
-```
-
-**Environment variables (.env)**:
-```bash
-PORT=3001
-ANTHROPIC_API_KEY=sk-ant-...
-```
-
-The Express server will:
-1. Handle `/api/*` routes directly
-2. Serve static files from `dist/`
-3. Fall back to `dist/index.html` for SPA routing
-
-### Option B: Split Deployment
-
-Separate hosting for frontend (CDN) and API (Node server):
-
-**API Server:**
-```bash
-# Start API-only server
-npm run start:api
-```
-
-**Environment variables (.env for API server)**:
-```bash
-PORT=3000
-API_ONLY=true
-ANTHROPIC_API_KEY=sk-ant-...
-ALLOWED_ORIGINS=https://your-frontend.com,https://www.your-frontend.com
-```
-
-**Frontend (Static Host):**
-```bash
-# Build with API URL configured
-VITE_API_URL=https://api.yourdomain.com npm run build
-
-# Deploy dist/ to your static host (Cloudflare Pages, Netlify, etc.)
-```
-
-**Environment variables (.env.production for frontend build)**:
-```bash
-VITE_API_URL=https://api.yourdomain.com
-```
-
-### Deployment Examples
-
-| Deployment | Frontend | API Server | Cost |
-|------------|----------|------------|------|
-| Combined | Railway | (same) | ~$5/mo |
-| Combined | Fly.io | (same) | Free tier |
-| Split | Cloudflare Pages (free) | Railway ($5/mo) | ~$5/mo |
-| Split | Netlify (free) | Fly.io (free) | Free |
-| Split | Vercel (free) | AWS Lambda | Pay-per-use |
-
----
-
-## Future API Routes
-
-To add more API routes, create new files in `server/api/`:
-
-```javascript
-// server/api/index.js
-import claudeRouter from "./claude.js";
-import imagesRouter from "./images.js";  // future
-import authRouter from "./auth.js";      // future
-
-router.use("/claude", claudeRouter);
-router.use("/images", imagesRouter);
-router.use("/auth", authRouter);
-```
-
----
-
-## Migration Order
-
-1. `npm install express vite-express dotenv cors`
-2. Create `server/api/index.js`
-3. Create `server/api/claude.js`
-4. Create `src/util/apiConfig.ts`
-5. Update `src/react/services/diagramAI.ts` to use `apiUrl()`
-6. Update `server.js` (root) with full Express + CORS setup
-7. Remove `/api/claude` proxy from `vite.config.ts`
-8. Update `package.json` scripts
-9. Test combined: `npm run dev` and verify Claude API works
-10. (Optional) Test split: Set `VITE_API_URL` and `API_ONLY=true`
-
----
-
-## Notes
-
-- **WebSocket server unchanged**: `server/server.js` (port 8080) runs separately
-- **Minimal frontend changes**: Only `diagramAI.ts` updated to use `apiUrl()`
-- **Environment variables**: `ANTHROPIC_API_KEY` already in `.env.local`
-- **Node version**: Requires Node 18+ for native `fetch`
-- **CORS**: Only enabled when `ALLOWED_ORIGINS` is set (split deployment)
-- **Backward compatible**: Works as combined deployment by default

-# Vite to Next.js Migration Plan
-
-## Goal
-Migrate from Vite to Next.js App Router to get proper API route support, with minimal changes to existing code.
-
-## Configuration
-- **Router**: App Router with `'use client'` on all pages
-- **Rendering**: CSR only (no SSR) - simplifies migration since BabylonJS can't SSR
-- **API Routes**: Claude API now, structured for future expansion
-- **External Proxies**: Keep sync/create-db/images as Next.js rewrites to deepdiagram.com
-
----
-
-## Phase 1: Setup (No Breaking Changes)
-
-### 1.1 Install Next.js
-```bash
-npm install next
-```
-
-### 1.2 Create `next.config.js`
-```javascript
-/** @type {import('next').NextConfig} */
-const nextConfig = {
-  async rewrites() {
-    return [
-      { source: '/sync/:path*', destination: 'https://www.deepdiagram.com/sync/:path*' },
-      { source: '/create-db', destination: 'https://www.deepdiagram.com/create-db' },
-      { source: '/api/images', destination: 'https://www.deepdiagram.com/api/images' },
-    ];
-  },
-  webpack: (config, { isServer }) => {
-    config.experiments = { ...config.experiments, asyncWebAssembly: true };
-    return config;
-  },
-};
-module.exports = nextConfig;
-```
-
-### 1.3 Update `tsconfig.json`
-Add path alias:
-```json
-"baseUrl": ".",
-"paths": { "@/*": ["./*"] }
-```
-
----
-
-## Phase 2: Create New Files
-
-### 2.1 `src/react/providers.tsx` (extract from webApp.tsx)
-- Move Auth0Provider and FeatureProvider wrapping here
-- Add `'use client'` directive
-- Handle window/document checks for SSR safety
-
-### 2.2 `app/layout.tsx`
-- Root layout with html/body tags
-- Metadata (title, favicon from current index.html)
-- Import global CSS
-
-### 2.3 `app/globals.css`
-```css
-@import '../src/react/styles.css';
-@import '@mantine/core/styles.css';
-```
-
-### 2.4 `app/api/claude/[...path]/route.ts`
-- POST handler that proxies to api.anthropic.com
-- Injects `ANTHROPIC_API_KEY` from env
-- Adds `x-api-key` and `anthropic-version` headers
-
-### 2.5 Page files (all with `'use client'`)
-| Route | File | Component |
-|-------|------|-----------|
-| `/` | `app/page.tsx` | About |
-| `/documentation` | `app/documentation/page.tsx` | Documentation |
-| `/examples` | `app/examples/page.tsx` | Examples |
-| `/pricing` | `app/pricing/page.tsx` | Pricing |
-| `/db/[visibility]/[db]` | `app/db/[visibility]/[db]/page.tsx` | VrExperience |
-| 404 | `app/not-found.tsx` | NotFound |
-
-### 2.6 `src/react/components/ProtectedPage.tsx`
-- Next.js version of route protection
-- Uses `useRouter` from `next/navigation` for redirects
-
----
-
-## Phase 3: Modify Existing Files
-
-### 3.1 `src/react/pages/vrExperience.tsx`
-**Changes:**
-- Remove `useParams()` from react-router-dom
-- Accept `visibility` and `db` as props instead
-- Replace `useNavigate()` with `useRouter()` from `next/navigation`
-
-### 3.2 `src/react/pageHeader.tsx`
-**Changes:**
-- Replace `import {Link} from "react-router-dom"` with `import Link from "next/link"`
-- Change `to={item.href}` to `href={item.href}` on Link components
-
-### 3.3 `src/react/marketing/about.tsx`
-**Changes:**
-- Replace `useNavigate()` with `useRouter()` from `next/navigation`
-- Change `navigate('/path')` to `router.push('/path')`
-
-### 3.4 `package.json`
-```json
-"scripts": {
-  "dev": "next dev -p 3001",
-  "build": "node versionBump.js && next build",
-  "start": "next start -p 3001",
-  "test": "vitest",
-  "socket": "node server/server.js",
-  "serverBuild": "cd server && tsc"
-}
-```
-
----
-
-## Phase 4: Delete Old Files
-
-| File | Reason |
-|------|--------|
-| `vite.config.ts` | Replaced by next.config.js |
-| `index.html` | Next.js generates HTML |
-| `src/webApp.ts` | Entry point no longer needed |
-| `src/react/webRouter.tsx` | Replaced by app/ routing |
-| `src/react/webApp.tsx` | Logic moved to providers.tsx |
-| `src/react/components/ProtectedRoute.tsx` | Replaced by ProtectedPage.tsx |
-
----
-
-## Critical Files to Modify
-
-- `src/react/pages/vrExperience.tsx` - useParams -> props
-- `src/react/pageHeader.tsx` - react-router Link -> Next.js Link
-- `src/react/marketing/about.tsx` - useNavigate -> useRouter
-- `src/react/webApp.tsx` - extract to providers.tsx
-- `package.json` - scripts update
-- `tsconfig.json` - path aliases
-
----
-
-## Migration Order
-
-1. Install next, create next.config.js
-2. Update tsconfig.json
-3. Create app/globals.css
-4. Create src/react/providers.tsx
-5. Create app/layout.tsx
-6. Create app/api/claude/[...path]/route.ts
-7. Create src/react/components/ProtectedPage.tsx
-8. Modify vrExperience.tsx (accept props)
-9. Create all app/*/page.tsx files
-10. Modify pageHeader.tsx (Next.js Link)
-11. Modify about.tsx (useRouter)
-12. Update package.json scripts
-13. Delete old files (vite.config.ts, index.html, webApp.ts, webRouter.tsx, webApp.tsx)
-14. Test all routes
-
----
-
-## Notes
-
-- **Havok WASM**: Move `HavokPhysics.wasm` to `public/` folder
-- **react-router-dom**: Can be removed from dependencies after migration
-- **vite devDependencies**: Can be removed (vite, vite-plugin-cp)

-# Self-Hosted Diagram Sharing with Express-PouchDB
-
-## Requirements (Confirmed)
-- **Storage**: In-memory (ephemeral) - lost on server restart
-- **Content**: Copy current diagram entities when creating share
-- **Expiration**: No expiration - links work until server restart
-- **Encryption**: None - keep it simple, anyone with link can access
-
-## Architecture
-
-```
-┌─────────────────────────────────────────────────┐
-│           Express Server (port 3001)             │
-├─────────────────────────────────────────────────┤

-└─────────────────────────────────────────────────┘
-         │
-         └── In-Memory PouchDB (per share UUID)
-```
-
-## Implementation Steps
-
-### Phase 1: Server-Side Setup
-
-#### 1.1 Add Dependencies
-```bash
-npm install express-pouchdb pouchdb-adapter-memory
-```
-
-#### 1.2 Create PouchDB Server Service
-**New file: `server/services/pouchdbServer.js`**
-- Initialize PouchDB with memory adapter
-- Track active share databases in a Map
-- Export `getShareDB(shareId)`, `shareExists(shareId)`, `createPouchDBMiddleware()`
-
-#### 1.3 Create Share API
-**New file: `server/api/share.js`**
-- `POST /api/share/create` - Generate UUID, create in-memory DB, copy entities
-- `GET /api/share/:id/exists` - Check if share exists
-- `GET /api/share/stats` - Debug endpoint for active shares
-
-#### 1.4 Update API Router
-**Edit: `server/api/index.js`**
-- Add `import shareRouter from "./share.js"`
-- Mount at `router.use("/share", shareRouter)`
-
-#### 1.5 Mount Express-PouchDB
-**Edit: `server.js`**
-- Import `createPouchDBMiddleware` from pouchdbServer.js
-- Mount at `app.use("/pouchdb", createPouchDBMiddleware())`
-
----
-
-### Phase 2: Client-Side Integration
-
-#### 2.1 Update URL Parsing
-**Edit: `src/util/functions/getPath.ts`**
-- Add `getPathInfo()` function returning `{ dbName, isShare, shareId }`
-- Detect `/share/:uuid` pattern
-
-#### 2.2 Update PouchDB Persistence Manager
-**Edit: `src/integration/database/pouchdbPersistenceManager.ts`**
-
-In `initLocal()`:
-- Call `getPathInfo()` to detect share URLs
-- If share: use `share-{uuid}` as local DB name, call `beginShareSync()`
-
-Add new method `beginShareSync(shareId)`:
-- Check share exists via `/api/share/:id/exists`
-- Connect to `${origin}/pouchdb/share-${shareId}`
-- Set up presence with `share-${shareId}` as DB name
-- Begin live sync (no encryption)
-
-#### 2.3 Add React Route
-**Edit: `src/react/webRouter.tsx`**
-- Add route `{ path: "/share/:uuid", element: <VrExperience isShare={true} /> }`
-- No ProtectedRoute wrapper (public access)
-
-#### 2.4 Add Share Button Handler
-**Edit: `src/react/pages/vrExperience.tsx`**
-- Add `isShare` prop
-- Add `handleShare()` function:
-  1. Get all entities from local PouchDB
-  2. POST to `/api/share/create` with entities
-  3. Copy resulting URL to clipboard
-  4. Show confirmation
-
----
-
-### Phase 3: Presence Integration
-
-The WebSocket presence system already routes by database name. Since shares use `share-{uuid}` as the database name, presence works automatically.
-
-**Edit: `server/server.js`** (WebSocket server)
-- Update `originIsAllowed()` to allow localhost for development
-
----

-1. User has a diagram open at `/db/public/mydiagram`
-2. Clicks "Share" button
-3. Client fetches all entities from local PouchDB
-4. POSTs to `/api/share/create` with entities
-5. Server creates in-memory DB, copies entities, returns UUID
-6. Client copies `https://server.com/share/{uuid}` to clipboard
-7. User shares link with collaborators
-
-### Joining a Share
-1. User navigates to `https://server.com/share/{uuid}`
-2. React Router renders VrExperience with `isShare=true`
-3. PouchdbPersistenceManager detects share URL
-4. Checks `/api/share/:uuid/exists` - returns true
-5. Creates local PouchDB `share-{uuid}`
-6. Connects to `/pouchdb/share-{uuid}` for sync
-7. Entities replicate to local, render in scene
-8. Presence WebSocket connects with `share-{uuid}` as room

-## Future Authentication (Not Implemented Now)
-
-Structure allows easy addition later:
-- express-pouchdb middleware can be wrapped with auth middleware
-- Share API can require JWT/session tokens
-- Could add password-protected shares
-- Could add read-only vs read-write permissions

-# Future Sync Strategy: Keeping Local and Public Clones in Sync
-
-## Current State (v1)
-
-- Sharing creates a **ONE-TIME COPY** from local to public
-- Copies diverge independently after sharing
-- No automatic sync between local and public versions
-- Local diagrams are browser-only (IndexedDB via PouchDB)
-- Public diagrams sync with server via express-pouchdb
-
-### URL Scheme
-
-| Route | Sync | Access | Status |
-|-------|------|--------|--------|
-| `/db/local/:id` | None | Browser-only | Implemented |
-| `/db/public/:id` | Yes | Anyone | Implemented |
-| `/db/private/:id` | Yes | Authorized users | Route only (no auth) |
-
-## Future Options
-
-### Option 1: Manual Push/Pull (Recommended for v2)
-
-Add explicit user-triggered sync between local and public copies.
-
-**Features:**
-- "Push to Public" button - sends local changes to public copy
-- "Pull from Public" button - gets public changes into local
-- Track `lastSyncedAt` timestamp
-- Show indicator when copies have diverged
-- Conflict resolution: Last write wins (simple) or user choice (advanced)
-
-**Pros:**
-- User stays in control
-- Clear mental model
-- Simple to implement incrementally
-
-**Cons:**
-- Manual effort required
-- Risk of forgetting to sync
-
-### Option 2: Automatic Background Sync
-
-Continuous bidirectional sync between local and public copies.
-
-**Features:**
-- Real-time sync like Google Docs
-- Works across devices
-- Offline-first with automatic merge
-
-**Pros:**
-- Seamless experience
-- Always up to date
-
-**Cons:**
-- Complex conflict resolution (may need CRDTs)
-- Higher performance overhead
-- Harder to reason about state
-
-### Option 3: Fork/Branch Model
-
-One-way relationship: local is "draft", public is "published".
-
-**Features:**
-- Push only (local → public)
-- No pull mechanism
-- Public is the "source of truth" once published
-
-**Pros:**
-- Clear mental model
-- No merge conflicts
-- Simple implementation
-
-**Cons:**
-- Cannot incorporate public changes back to local
-- Multiple people can't collaborate on draft
-
-## Recommended Implementation (v2)
-
-Implement **Option 1 (Manual Push/Pull)** as it provides the best balance of user control and simplicity.
-
-### Data Model Changes
-
-Add to diagram directory entry:
-```typescript
-interface DiagramEntry {
-  _id: string;
-  name: string;
-  description: string;
-  storageType: 'local' | 'public' | 'private';
-  createdAt: string;
-
-  // New fields for sync tracking
-  publicCopyId?: string;      // ID of the public clone (if shared)
-  lastPushedAt?: string;      // When changes were last pushed to public
-  lastPulledAt?: string;      // When public changes were last pulled
-  publicVersion?: number;     // Version number of public copy at last sync
-}
-```
-
-### API Endpoints
-
-```typescript
-// Push local changes to public
-POST /api/sync/push
-Body: { localDbName: string, publicDbName: string }
-Response: { success: boolean, documentsUpdated: number }
-
-// Pull public changes to local
-POST /api/sync/pull
-Body: { localDbName: string, publicDbName: string }
-Response: { success: boolean, documentsUpdated: number }
-
-// Check if copies have diverged
-GET /api/sync/status?local={localDbName}&public={publicDbName}
-Response: {
-  diverged: boolean,
-  localChanges: number,
-  publicChanges: number,
-  lastSyncedAt: string
-}
-```
-
-### UI Components
-
-1. **Sync Status Indicator**
-   - Shows in header when viewing a local diagram that has a public copy
-   - Green check: In sync
-   - Orange dot: Changes pending
-   - Red warning: Conflicts detected
-
-2. **Push/Pull Buttons**
-   - In hamburger menu under "Share" section
-   - "Push to Public" - shows confirmation with change count
-   - "Pull from Public" - shows confirmation with change count
-
-3. **Divergence Warning Badge**
-   - Shows on diagram card in Manage Diagrams modal
-   - Indicates when local and public have diverged
-
-4. **Conflict Resolution Dialog**
-   - Shows when both local and public have changes to same entity
-   - Options: Keep Local, Keep Public, Keep Both (creates duplicate)
-
-### Implementation Phases
-
-**Phase 1: Tracking**
-- Add `publicCopyId` when sharing local → public
-- Track sharing relationship in directory
-
-**Phase 2: Push**
-- Implement push from local to public
-- Overwrite public with local changes
-- Update `lastPushedAt` timestamp
-
-**Phase 3: Pull**
-- Implement pull from public to local
-- Merge public changes into local
-- Update `lastPulledAt` timestamp
-
-**Phase 4: Status**
-- Implement divergence detection
-- Add UI indicators
-- Show sync status in Manage Diagrams
-
-**Phase 5: Conflict Resolution**
-- Detect entity-level conflicts
-- Show resolution dialog
-- Allow user to choose resolution strategy
-
-## Migration Notes
-
-Existing diagrams without `storageType` are treated as `public` for backwards compatibility. When such diagrams are loaded, the UI should work correctly but sync tracking features won't be available until the diagram metadata is updated.
-
-## Security Considerations
-
-- Push/pull operations should validate that the user has access to both databases
-- Public databases remain world-readable/writable
-- Private database sync will require authentication tokens
-- Rate limiting should be applied to sync operations

+# Feature Configuration Testing
+
+This directory contains static JSON files for testing different user tiers locally.
+
+## Available Configurations
+
+### Default: `features` (none tier)
+- **What you see**: Only the home page
+- **All pages and features**: Disabled
+- **Use case**: Unauthenticated users or when API is unavailable
+
+### Free Tier: `features-free.json`
+- **Pages**: All marketing pages + VR Experience
+- **Features**: Basic diagram creation, management, immersive mode
+- **Limits**: 6 diagrams max, 100MB storage
+- **No access to**: Templates, private/encrypted designs, collaboration
+
+### Basic Tier: `features-basic.json`
+- **Pages**: All pages available
+- **Features**: Free features + templates + private designs
+- **Limits**: 25 diagrams max, 500MB storage
+- **No access to**: Encrypted designs, collaboration
+
+### Pro Tier: `features-pro.json`
+- **Pages**: All pages available
+- **Features**: Everything unlocked
+- **Limits**: Unlimited (indicated by -1)
+
+## How to Test Locally
+
+### Method 1: Copy the file you want to test
+```bash
+# Test free tier
+cp public/api/user/features-free.json public/api/user/features
+
+# Test basic tier
+cp public/api/user/features-basic.json public/api/user/features
+
+# Test pro tier
+cp public/api/user/features-pro.json public/api/user/features
+
+# Test none/default (locked down)
+cp public/api/user/features-none.json public/api/user/features
+```
+
+### Method 2: Symlink (easier for switching)
+```bash
+# Remove the default file
+rm public/api/user/features
+
+# Create a symlink to the tier you want to test
+ln -s features-free.json public/api/user/features
+# or
+ln -s features-basic.json public/api/user/features
+# or
+ln -s features-pro.json public/api/user/features
+```
+
+## What Changes Between Tiers
+
+| Feature | None | Free | Basic | Pro |
+|---------|------|------|-------|-----|
+| Pages (Examples, Docs, Pricing) | ❌ | ✅ | ✅ | ✅ |
+| VR Experience | ❌ | ✅ | ✅ | ✅ |
+| Create Diagram | ❌ | ✅ | ✅ | ✅ |
+| Create From Template | ❌ | ❌ | ✅ | ✅ |
+| Private Designs | ❌ | ❌ | ✅ | ✅ |
+| Encrypted Designs | ❌ | ❌ | ❌ | ✅ |
+| Share/Collaborate | ❌ | ❌ | ❌ | ✅ |
+| Max Diagrams | 0 | 6 | 25 | ∞ |
+| Storage | 0 | 100MB | 500MB | ∞ |
+
+## Backend Implementation (Future)
+
+When you're ready to implement the backend, create an endpoint at:
+```
+GET https://www.deepdiagram.com/api/user/features
+```
+
+The endpoint should:
+1. Validate the Auth0 JWT token from `Authorization: Bearer <token>` header
+2. Query the user's subscription tier from your database
+3. Return JSON matching one of these structures based on their tier
+4. Handle errors gracefully (401 for invalid token, 403 for unauthorized)
+
+The frontend will automatically fall back to the static `features` file if:
+- User is not authenticated
+- API returns an error
+- Network request fails

-
-Available entity shapes: box, sphere, cylinder, cone, plane, person
-Available colors: red, blue, green, yellow, orange, purple, cyan, pink, white, black, brown, gray (or any hex color like #ff5500)
-
-IMPORTANT - Handling directional commands (left, right, forward, back, in front of me, etc.):
-When the user uses relative directions, you MUST first call get_camera_position to get their current view.
-The response provides:
-- Their world position
-- Ground-projected forward/right vectors (accounts for camera being on a moving platform)
-- Pre-calculated positions for forward/back/left/right at 2m distance
-
-Use the ground-plane directions for intuitive placement - these ignore vertical look angle so "forward" means "forward on the ground" not "where I'm looking vertically".
-
-Position coordinates (when not using relative directions):
-- x: world left/right
-- y: up/down (1.5 is eye level, 0 is floor)
-- z: world forward/backward
-
-When creating diagrams, think about good spatial layout:
-- Spread entities apart to avoid overlap (at least 0.5 units)
-- Use y=1.5 for entities at eye level
-- For relative placement, use get_camera_position first
-
-Always use the provided tools to create, modify, or interact with entities. Be concise in your responses.`;
