+# StrategyStack Deployment Guide
+
+## Customer-Ready Multi-Tenant Platform
+
+This guide explains how to deploy and configure the StrategyStack Recovery, Enrichment & Outreach Platform for production use with Hugging Face Spaces.
+
+---
+
+## ✅ What's Already Implemented
+
+The platform now includes:
+
+### 1. **OAuth Authentication**
+- 🔒 Sign in with Hugging Face button
+- Automatic user authentication via `gr.OAuthProfile`
+- All dashboard panels protected behind authentication
+- Unauthenticated users see clear login prompts
+
+### 2. **Per-User Data Isolation**
+- Each user's data stored in `/data/users/{username}/`
+- Zero data sharing between users
+- Customer data ownership model (you don't hold their data)
+- Automatic user directory creation on first access
+
+### 3. **Multi-Tenant Architecture**
+- Session-based data loading
+- Username displayed in all panels
+- Sample data for seamless new user onboarding
+- Refresh buttons for manual data reloading
+
+### 4. **Data Types Supported**
+- Consent events (consent_events.json)
+- Cadence branches (branches.json)
+- Diagnostic logs (diagnostics.json)
+- Extensible to any JSON-serializable data
+
+---
+
+## 🚀 Deployment Steps
+
+### Step 1: Enable Persistent Storage
+
+**CRITICAL**: Hugging Face Spaces must have persistent storage enabled for user data to persist between sessions.
+
+1. Go to your Space: https://huggingface.co/spaces/StrategyStack/README
+2. Click on **Settings** tab
+3. Scroll to **Storage** section
+4. Enable **Persistent storage**
+5. Select storage size (recommended: 20GB minimum for multi-tenant use)
+6. Save changes
+
+**Note**: Persistent storage is mounted at `/data` and persists across Space restarts.
+
+### Step 2: Configure Space Secrets (Optional)
+
+If your application needs API keys for external services:
+
+1. Go to **Settings** tab
+2. Scroll to **Variables and secrets** section
+3. Add secrets:
+   - `LINKEDIN_API_KEY` (if using LinkedIn integration)
+   - `TWILIO_API_KEY` (if using Twilio integration)
+   - `SALESFORCE_API_KEY` (if using Salesforce integration)
+   - Any other API keys your agents require
+
+4. Access in code:
+```python
+import os
+linkedin_key = os.getenv('LINKEDIN_API_KEY')
+```
+
+### Step 3: Verify OAuth Configuration
+
+The OAuth setup is already complete:
+- ✅ README.md has `hf_oauth: true` in metadata (line 9)
+- ✅ app.py has `gr.LoginButton()` component
+- ✅ All functions accept `gr.OAuthProfile` parameter
+
+No additional OAuth configuration needed!
+
+### Step 4: Test Multi-User Access
+
+1. Open the Space: https://huggingface.co/spaces/StrategyStack/README
+2. Click **Sign in with Hugging Face**
+3. Verify you see:
+   - Your username displayed in panels
+   - Sample data (since you're a new user)
+   - All four dashboard tabs accessible
+
+4. Test with a second account:
+   - Sign out
+   - Sign in with different HF account
+   - Verify data is separate from first account
+
+---
+
+## 📊 Monitoring & Operations
+
+### Viewing Logs
+
+1. Go to Space page
+2. Click on **Logs** dropdown (top right)
+3. Select:
+   - **Build** - See build logs
+   - **Container** - See runtime application logs
+
+### Space Status
+
+- 🟢 **Running** - Space is live and accepting users
+- 🔵 **Building** - Space is being rebuilt after code changes
+- 🔴 **Runtime Error** - Check container logs for errors
+
+### Restarting the Space
+
+If you need to restart:
+
+1. Go to **Settings** tab
+2. Scroll to **Sleep time settings**
+3. Click **Restart Space**
+
+**Note**: Persistent storage data survives restarts!
+

+
+## 💾 Data Management
+
+### User Data Structure
+
+```
+/data/
+└── users/
+    ├── username1/
+    │   ├── consent_events.json
+    │   ├── branches.json
+    │   └── diagnostics.json
+    ├── username2/
+    │   ├── consent_events.json
+    │   ├── branches.json
+    │   └── diagnostics.json
+    └── ...
+```
+
+### Accessing User Data
+
+The app provides helper functions:
+
+```python
+# Load user data
+user_events = load_user_data(username, "consent_events")
+
+# Save user data
+save_user_data(username, "consent_events", data)
+
+# Get user directory
+user_dir = get_user_dir(username)
+```
+
+### Backup Strategy
+
+**Important**: While persistent storage is durable, implement regular backups:
+
+1. **Option A - Manual Backup**:
+   - Use Hugging Face Hub's file browser
+   - Download `/data` directory contents
+   - Store securely off-platform
+
+2. **Option B - Automated Backup** (Future Enhancement):
+   - Add scheduled backup function
+   - Export to external cloud storage
+   - Implement via Space cron or external scheduler
+
+---
+
+## ⚙️ Configuration Options
+
+### Customizing Data Storage Location
+
+Edit `app.py` line 9:
+
+```python
+DATA_DIR = Path("/data")  # Change if needed
+```
+
+### Adding New Data Types
+
+1. Define new data structure (JSON-serializable)
+2. Use existing functions:
+```python
+# Save new data type
+save_user_data(username, "campaigns", campaign_data)
+
+# Load new data type
+campaigns = load_user_data(username, "campaigns")
+```
+
+3. Create UI panel to display/edit
+
+### Customizing Authentication Messages
+
+Edit the authentication check in panel functions (app.py):
+
+```python
+if profile is None:
+    return "Your custom auth message here"
+```
+
+---
+
+## 🛡️ Security Considerations
+
+### Data Isolation
+
+- ✅ Users cannot access other users' data
+- ✅ File paths use username for isolation
+- ✅ No centralized data storage (privacy by design)
+
+### Authentication
+
+- ✅ OAuth via Hugging Face (no password management needed)
+- ✅ Profile information provided by HF OAuth
+- ✅ Automatic session management
+
+### API Keys
+
+- ⚠️ Store API keys in Space Secrets (not in code)
+- ⚠️ Never commit API keys to repository
+- ⚠️ Use environment variables for all sensitive data
