# 🚀 Complete App Workflow Guide: End-to-End Implementation
## 📋 **Overview**
This guide documents the complete end-to-end workflow for app creation, marketplace listing, purchase, and deployment tracking in the Project Mycelium. This pattern can be replicated for service-provider workflows and node slice rentals.
## 🎯 **Complete Workflow: App Provider → Customer**
### **Step 1: App Creation (Provider Side)**
- **User**: App Provider (e.g., `user1@example.com`)
- **Action**: `/dashboard/app-provider` → Create new app
- **Backend**: [`add_app_api`](../src/controllers/dashboard.rs:4716) → [`UserPersistence::add_user_app`](../src/services/user_persistence.rs:1091)
- **Data**: App saved to provider's `apps` array in JSON
- **Marketplace**: [`create_marketplace_product_from_app`](../src/controllers/marketplace.rs:619) → [`MockDataService::add_product`](../src/controllers/dashboard.rs:4727)
### **Step 2: Marketplace Visibility**
- **User**: Any user
- **Action**: `/marketplace/applications`
- **Backend**: [`applications_page`](../src/controllers/marketplace.rs:600) aggregates apps from all users
- **Data Source**: Scans all `user_data/*.json` files → `apps` arrays
- **Result**: Provider's app visible to all users
### **Step 3: App Purchase (Customer Side)**
- **User**: Customer (e.g., `user4@example.com`)
- **Action**: Marketplace → Add to cart → Checkout
- **Backend**: [`OrderService::checkout`](../src/services/order.rs:415) → [`create_app_deployments_from_order`](../src/services/order.rs:476)
- **Result**: Deployment records created for both provider and customer
### **Step 4: Deployment Tracking**
- **Provider Side**: Deployment added to provider's `app_deployments` with customer info + revenue
- **Customer Side**: Deployment added to customer's `app_deployments` with app info
- **Cross-Reference**: Same deployment ID links both perspectives
### **Step 5: Dashboard Display**
- **Provider Dashboard**: Shows published apps + customer deployments
- **Customer Dashboard**: Shows purchased apps (derived from deployments)
## 🏗️ **Data Architecture**
### **Provider Data Structure**
```json
// user1_at_example_com.json (App Provider)
{
"apps": [
{
"id": "app_001",
"name": "My App",
"status": "Active"
}
],
"app_deployments": [
{
"id": "dep-001",
"app_id": "app_001",
"customer_email": "user4@example.com", // Customer who purchased
"monthly_revenue": 120 // Provider earns revenue
}
]
}
```
### **Customer Data Structure**
```json
// user4_at_example_com.json (Customer)
{
"apps": [], // Empty - customer didn't publish any apps
"app_deployments": [
{
"id": "dep-001", // Same deployment ID
"app_id": "app_001",
"customer_email": "user4@example.com", // Self-reference
"monthly_revenue": 0 // Customer doesn't earn from purchase
}
]
}
```
## 🔧 **Critical Implementation Details**
### **1. Data Separation Logic**
#### **User Dashboard (`/dashboard/user`)**
```rust
/// Shows purchased apps - derived from deployments where user is customer
pub fn get_user_applications(&self, user_email: &str) -> Vec<PublishedApp> {
persistent_data.app_deployments
.filter(|d| d.status == "Active" && d.customer_email == user_email)
.map(|deployment| /* convert to app view */)
}
```
#### **App Provider Dashboard (`/dashboard/app-provider`)**
```rust
/// Shows published apps - from apps array
let fresh_apps = UserPersistence::get_user_apps(&user_email);
/// Shows deployments of published apps only
let user_published_app_ids: HashSet<String> = fresh_apps.iter()
.map(|app| app.id.clone())
.collect();
let filtered_deployments = fresh_deployments.iter()
.filter(|d| user_published_app_ids.contains(&d.app_id))
```
### **2. Role-Based Display**
#### **App Provider Perspective**
- **`/dashboard/app-provider`**:
- "My Published Apps" → From `apps` array
- "Active Deployments" → From `app_deployments` filtered by published apps
- **`/dashboard/user`**:
- "My Applications" → Empty (provider didn't purchase apps)
#### **Customer Perspective**
- **`/dashboard/user`**:
- "My Applications" → From `app_deployments` where customer_email matches
- **`/dashboard/app-provider`**:
- Empty sections (customer didn't publish apps)
### **3. Cross-User Deployment Counting**
```rust
/// Count deployments across all users for app provider stats
fn count_cross_user_deployments(app_provider_email: &str) -> HashMap<String, i32> {
// Scan all user_data/*.json files
// Count deployments of this provider's apps
// Update provider's app.deployments count
}
```
## 🎨 **Frontend Implementation**
### **User Dashboard JavaScript**
```javascript
// Populate purchased applications table
populateApplicationsTable() {
const applications = this.userData.applications || []; // From get_user_applications()
// Display apps user purchased
}
```
### **App Provider Dashboard**
```javascript
// Shows published apps and their deployments
// Data comes from app_provider_data_api with proper filtering
```
## 🔄 **Order Processing Flow**
### **Purchase → Deployment Creation**
```rust
// In OrderService::create_app_deployments_from_order()
for item in order.items {
if item.product_category == "application" {
// Find app provider
let app_provider_email = find_app_provider(&item.product_id);
// Create deployment record
let deployment = AppDeployment::builder()
.app_id(&item.product_id)
.customer_email(&customer_email)
.build();
// Add to provider's data (for tracking)
UserPersistence::add_user_app_deployment(&app_provider_email, deployment.clone());
// Add to customer's data (for user dashboard)
UserPersistence::add_user_app_deployment(&customer_email, deployment);
}
}
```
## 🎯 **Replication Pattern for Other Workflows**
### **Service Provider Workflow**
1. **Creation**: Service provider creates service → `services` array
2. **Marketplace**: Service appears in `/marketplace/services`
3. **Purchase**: Customer books service → `service_requests` array
4. **Tracking**: Provider sees requests, customer sees bookings
### **Node Slice Workflow**
1. **Creation**: Farmer creates slice → `slice_products` array
2. **Marketplace**: Slice appears in `/marketplace/compute`
3. **Rental**: Customer rents slice → `active_product_rentals` array
4. **Tracking**: Farmer sees rentals, customer sees active resources
## 📊 **Key Success Factors**
### **1. Proper Data Separation**
- Publishers see their published items + customer usage
- Customers see their purchased items only
- No role confusion or data duplication
### **2. Cross-User Tracking**
- Same deployment/booking ID in both users' files
- Different perspectives (provider vs customer)
- Proper revenue attribution
### **3. Role-Based Filtering**
- User dashboard: Filter by `customer_email == current_user`
- Provider dashboard: Filter by `published_items.contains(item_id)`
### **4. Real-Time Updates**
- Marketplace immediately shows new items
- Purchase creates records for both parties
- Dashboards reflect current state
## 🏆 **Production Readiness**
This pattern provides:
- ✅ Complete multi-user workflows
- ✅ Real data persistence
- ✅ Proper role separation
- ✅ Cross-user tracking
- ✅ Revenue attribution
- ✅ Integration-ready architecture
The same pattern can be applied to any producer/consumer workflow in the marketplace, ensuring consistent behavior across all product types.

# Project Mycelium - Comprehensive Slice Management Plan
## Complete UX Vision & Implementation Strategy
---
## 🌟 **Vision & End Goals**
### **The Big Picture**
Transform the Project Mycelium from a **node-centric** to a **slice-centric** compute marketplace, where users can rent standardized compute units instead of entire nodes. This democratizes access to ThreeFold's decentralized infrastructure by making it more affordable and accessible.
### **Core Value Proposition**
- **For Users**: Rent exactly what you need (1 vCPU, 4GB RAM, 200GB storage) instead of entire nodes
- **For Farmers**: Maximize node utilization by selling multiple slices per node
- **For ThreeFold**: Increase marketplace liquidity and accessibility
### **Key Success Metrics**
1. **Increased marketplace activity** - More rentals due to lower entry barriers
2. **Higher node utilization** - Farmers earn more from partially-used nodes
3. **Better user experience** - Clear, standardized compute units
4. **Reduced complexity** - No more guessing about resource allocation
---
## 🎯 **Complete User Experience Design**
### **🚜 Farmer Journey: From Node to Slices**
#### **Current State (Node-based)**
```
Farmer adds 32 vCPU, 128GB RAM, 2TB storage node
→ Sets price for entire node ($200/month)
→ Node sits empty until someone needs ALL resources
→ Low utilization, missed revenue
```
#### **Target State (Slice-based)**
```
Farmer adds 32 vCPU, 128GB RAM, 2TB storage node
→ System automatically calculates: 32 slices available
(min(32/1, 128/4, 2000/200) = min(32, 32, 10) = 10 slices)
→ Farmer sets price per slice ($25/month per slice)
→ 10 different users can rent individual slices
→ Maximum utilization, predictable revenue
```
#### **Detailed Farmer UX Flow**
**Step 1: Node Addition (Enhanced)**
- Farmer navigates to "Add Node" in dashboard
- Enters ThreeFold Grid node ID
- System fetches real-time capacity from gridproxy API
- **NEW**: System automatically shows "This node can provide X slices"
- **NEW**: Farmer sees potential monthly revenue: "Up to $X/month if all slices rented"
**Step 2: Slice Configuration (New)**
- Farmer sets price per slice (within platform min/max limits)
- **NEW**: Farmer sets node-level SLA commitments:
- Minimum uptime guarantee (e.g., 99.5%)
- Minimum bandwidth guarantee (e.g., 100 Mbps)
- **NEW**: System shows competitive analysis: "Similar nodes in your region charge $X-Y"
- Farmer confirms and publishes slices to marketplace
**Step 3: Slice Management Dashboard (Enhanced)**
- **NEW**: Real-time slice allocation view:
```
Node: farmer-node-001 (Belgium)
├── Slice 1: 🟢 Rented by user@example.com (expires: 2025-02-15)
├── Slice 2: 🟢 Rented by dev@startup.com (expires: 2025-03-01)
├── Slice 3: 🟡 Available
└── Slice 4: 🟡 Available
```
- **NEW**: Revenue tracking: "This month: $150 earned, $100 pending"
- **NEW**: Performance monitoring: "Uptime: 99.8% (above SLA)"
**Step 4: Ongoing Management (Enhanced)**
- Farmer receives notifications when slices are rented/released
- **NEW**: Automatic price suggestions based on demand
- **NEW**: SLA monitoring alerts if uptime/bandwidth drops below commitments
### **👤 User Journey: From Complex to Simple**
#### **Current State (Node-based)**
```
User needs 1 vCPU for small app
→ Must rent entire 32 vCPU node ($200/month)
→ Wastes 31 vCPUs, overpays by 3100%
→ Complex resource planning required
```
#### **Target State (Slice-based)**
```
User needs 1 vCPU for small app
→ Rents 1 slice with exactly 1 vCPU, 4GB RAM, 200GB storage
→ Pays fair price ($25/month)
→ Simple, predictable resources
```
#### **Detailed User UX Flow**
**Step 1: Marketplace Discovery (Enhanced)**
- User visits `/marketplace/compute`
- **NEW**: Clear slice-based interface:
```
🍰 Available Compute Slices
Each slice provides:
• 1 vCPU core
• 4GB RAM
• 200GB SSD storage
[Filter by Location] [Filter by Price] [Filter by SLA]
```
**Step 2: Slice Selection (New)**
- **NEW**: Standardized slice cards showing:
```
📍 Belgium • Node: farmer-node-001
💰 $25/month • 🔄 99.8% uptime • 🌐 150 Mbps
Resources (guaranteed):
🖥️ 1 vCPU 💾 4GB RAM 💿 200GB Storage
[Rent This Slice]
```
- **NEW**: No complex resource calculations needed
- **NEW**: Clear SLA commitments visible upfront
**Step 3: Rental Process (New)**
- User clicks "Rent This Slice"
- **NEW**: Simple rental modal:
```
Rent Compute Slice
Duration: [1 month ▼] [3 months] [6 months] [12 months]
Total cost: $25/month
You'll get:
• Dedicated 1 vCPU, 4GB RAM, 200GB storage
• Access credentials within 5 minutes
• 99.8% uptime SLA guarantee
[Confirm Rental - $25]
```
**Step 4: Instant Access (Enhanced)**
- **NEW**: Atomic allocation prevents double-booking
- **NEW**: Immediate access credentials provided
- **NEW**: Clear resource boundaries (no sharing confusion)
**Step 5: Management Dashboard (Enhanced)**
- **NEW**: Simple slice tracking:
```

## 🏗️ **Technical Architecture & Implementation**
### **System Design Principles**
1. **Leverage Existing Infrastructure**: Build on robust [`GridService`](projectmycelium/src/services/grid.rs:1), [`FarmNode`](projectmycelium/src/models/user.rs:164), [`NodeMarketplaceService`](projectmycelium/src/services/node_marketplace.rs:1)
2. **Atomic Operations**: Prevent slice double-booking with file locking
3. **Clear Separation of Concerns**:
- **Node-level**: SLA characteristics (uptime, bandwidth, location)
- **Slice-level**: Compute resources (1 vCPU, 4GB RAM, 200GB storage)
4. **Backward Compatibility**: Existing node rentals continue working
### **Core Algorithm: Slice Calculation**
```rust
// The heart of the system: How many slices can a node provide?
fn calculate_max_slices(node: &FarmNode) -> i32 {
let available_cpu = node.capacity.cpu_cores - node.used_capacity.cpu_cores;
let available_ram = node.capacity.memory_gb - node.used_capacity.memory_gb;
let available_storage = node.capacity.storage_gb - node.used_capacity.storage_gb;
// Each slice needs: 1 vCPU, 4GB RAM, 200GB storage
let max_by_cpu = available_cpu / 1;
let max_by_ram = available_ram / 4;
let max_by_storage = available_storage / 200;
// Bottleneck determines maximum slices
std::cmp::min(std::cmp::min(max_by_cpu, max_by_ram), max_by_storage)
}
```
**Example Calculations**:
- **High-CPU node**: 32 vCPU, 64GB RAM, 1TB storage → `min(32, 16, 5) = 5 slices`
- **Balanced node**: 16 vCPU, 64GB RAM, 4TB storage → `min(16, 16, 20) = 16 slices`
- **Storage-heavy node**: 8 vCPU, 32GB RAM, 10TB storage → `min(8, 8, 50) = 8 slices`
### **Data Model Enhancement**
#### **Enhanced FarmNode Structure**
```rust
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct FarmNode {
// ... ALL existing fields remain unchanged ...
// NEW: Slice management
pub calculated_slices: Vec<CalculatedSlice>,
pub allocated_slices: Vec<AllocatedSlice>,
pub slice_price_per_hour: Decimal,
// NEW: Node-level SLA (inherited by all slices)
pub min_uptime_sla: f32, // e.g., 99.5%
pub min_bandwidth_mbps: i32, // e.g., 100 Mbps
pub price_locked: bool, // Prevent farmer price manipulation
}
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct CalculatedSlice {
pub id: String, // e.g., "node123_slice_1"
pub cpu_cores: i32, // Always 1
pub memory_gb: i32, // Always 4
pub storage_gb: i32, // Always 200
pub status: SliceStatus, // Available/Reserved/Allocated
}
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct AllocatedSlice {
pub slice_id: String,
pub renter_email: String,
pub rental_start: DateTime<Utc>,
pub rental_end: Option<DateTime<Utc>>,
pub monthly_cost: Decimal,
}
```
### **Service Architecture**
#### **1. SliceCalculatorService** (New)
- **Purpose**: Calculate available slices from node capacity
- **Key Method**: `calculate_available_slices(node: &FarmNode) -> Vec<CalculatedSlice>`
- **Algorithm**: Uses min(CPU/1, RAM/4, Storage/200) formula
#### **2. SliceAllocationService** (New)
- **Purpose**: Atomic slice rental with conflict prevention
- **Key Method**: `rent_slice_atomic(node_id, slice_id, user_email, duration)`
- **Features**: File locking, double-booking prevention, automatic billing
#### **3. Enhanced GridService**
- **New Method**: `fetch_node_with_slices(node_id) -> FarmNode`
- **Enhancement**: Automatically calculates slices when fetching from gridproxy
#### **4. Enhanced NodeMarketplaceService**
- **New Method**: `get_all_available_slices() -> Vec<SliceMarketplaceInfo>`
- **Enhancement**: Scans all farmer data, returns available slices instead of nodes
### **Marketplace Integration**
#### **Enhanced `/marketplace/compute` Endpoint**
```rust
// Transform from node-centric to slice-centric
pub async fn compute_resources() -> Result<impl Responder> {
// Get all available slices from all farmers
let available_slices = node_marketplace_service.get_all_available_slices();
// Apply filters (location, price, SLA requirements)
let filtered_slices = apply_slice_filters(&available_slices, &query);
// Paginate and format for display
let slice_products = format_slices_for_display(&filtered_slices);
ctx.insert("slices", &slice_products);
render_template(&tmpl, "marketplace/compute.html", &ctx)
}
```
#### **New `/api/marketplace/rent-slice` Endpoint**
```rust
pub async fn rent_slice(request: web::Json<RentSliceRequest>) -> Result<impl Responder> {
match SliceAllocationService::rent_slice_atomic(
&request.node_id,
&request.slice_id,
&user_email,
request.duration_months,
) {
Ok(_) => Ok(HttpResponse::Ok().json({
"success": true,
"message": "Slice rented successfully",
"access_info": "Credentials will be provided within 5 minutes"
})),
Err(e) => Ok(HttpResponse::BadRequest().json({
"success": false,
"message": e
}))
}
}
```

# Project Mycelium - Grand Architecture Guide
## Complete Vision & Implementation Guide for AI Coders
### 🎯 **Project Vision**
The Project Mycelium is a **production-ready, fully functional e-commerce platform** built in Rust that demonstrates a complete decentralized marketplace ecosystem. It's designed to be **immediately testable by humans** in a browser while being **integration-ready** for real-world deployment.
---
## 🏗️ **Architectural Philosophy**
### **Core Principles**
1. **Builder Pattern Everywhere**: Every service, model, and context uses builders
2. **Real Persistent Data**: JSON files in `./user_data/` serve as the production database
3. **Complete User Personas**: Service providers, app providers, farmers, and users all fully functional
4. **Integration-Ready**: Designed for easy external API integration (Stripe, Grid, etc.)
5. **Human-Testable**: Every feature works end-to-end in the browser
### **Data Flow Architecture**
```mermaid
graph TD
A[User Action] --> B[Controller with Builder Pattern]
B --> C[Service Layer with Business Logic]
C --> D[JSON Database in ./user_data/]
D --> E[Real-time UI Updates]
E --> F[Marketplace Integration]
F --> G[Cross-Persona Interactions]
```
---
## 📊 **Data Architecture: Real Persistent Storage**
### **JSON Database Structure**
```
./user_data/
├── user1_at_example_com.json # Service provider with real services
├── user2_at_example_com.json # App provider with published apps
├── user3_at_example_com.json # Farmer with nodes and earnings
├── user4_at_example_com.json # Regular user with purchases
└── user5_at_example_com.json # Mixed persona user
```
### **UserPersistentData: The Complete User Model**
```rust
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct UserPersistentData {
// Core user data
pub user_email: String,
pub wallet_balance: Decimal, // Real TFP balance
pub transactions: Vec<Transaction>, // Real transaction history
// Service Provider persona
pub services: Vec<Service>, // Created services → marketplace
pub service_requests: Vec<ServiceRequest>, // Client requests
// App Provider persona
pub apps: Vec<PublishedApp>, // Published apps → marketplace
pub app_deployments: Vec<AppDeployment>, // Active deployments
// Farmer persona
pub nodes: Vec<FarmNode>, // Farm nodes with real metrics
pub farmer_earnings: Vec<EarningsRecord>, // Earnings tracking
pub farmer_settings: Option<FarmerSettings>,
// User persona
pub user_activities: Vec<UserActivity>, // Activity tracking
pub user_preferences: Option<UserPreferences>,
pub usage_statistics: Option<UsageStatistics>,
// Financial data
pub pool_positions: HashMap<String, PoolPosition>, // TFP pool investments
// Profile data
pub name: Option<String>,
pub country: Option<String>,
pub timezone: Option<String>,
}
```
---
## 🏗️ **Builder Pattern Implementation**
### **The Builder Philosophy**
Every object construction in the marketplace uses the builder pattern. This ensures:
- **Consistent API**: All services constructed the same way
- **Validation**: Required fields enforced at build time
- **Extensibility**: Easy to add new configuration options
- **Error Handling**: Proper Result types with meaningful errors
### **Service Builder Example**
```rust
// Every service follows this pattern
let product_service = ProductService::builder()
.currency_service(currency_service.clone())
.cache_enabled(true)
.default_category("compute")
.build()?;
let farmer_service = FarmerService::builder()
.auto_sync_enabled(true)
.metrics_collection(true)
.build()?;
```
### **Context Builder Pattern**
```rust
// Every controller uses ContextBuilder for templates
let mut ctx = ContextBuilder::new()
.active_page("dashboard")
.active_section("farmer")
.user_type("farmer")
.build();
```
---
## 🎭 **User Personas & Complete Workflows**
### **1. Service Provider Persona** ✅ **COMPLETE**
**Workflow**: Create Service → JSON Storage → Marketplace Display → Purchase by Others
```rust
// Real implementation flow
pub async fn add_service(form: ServiceForm, session: Session) -> Result<impl Responder> {
// 1. Build service using builder pattern
let service = Service::builder()
.name(form.name)
.description(form.description)
.price(form.price)
.build()?;
// 2. Save to real JSON database
UserPersistence::add_user_service(&user_email, service.clone())?;
// 3. Register in marketplace for immediate availability
let marketplace_product = create_marketplace_product_from_service(&service);
MockDataService::instance().lock().unwrap().add_product(marketplace_product);
// Service now appears in /marketplace/services immediately
}
```
### **2. App Provider Persona** ✅ **COMPLETE**
**Workflow**: Publish App → JSON Storage → Marketplace Display → Deployment Tracking
```rust
pub async fn publish_app(form: AppForm, session: Session) -> Result<impl Responder> {
let app = PublishedApp::builder()
.name(form.name)
.category(form.category)
.version("1.0.0")
.build()?;
UserPersistence::add_user_app(&user_email, app.clone())?;
// Auto-register in marketplace
let marketplace_product = create_marketplace_product_from_app(&app);
MockDataService::instance().lock().unwrap().add_product(marketplace_product);
}
```
### **3. Farmer Persona** 🔄 **TO COMPLETE**
**Workflow**: Manage Nodes → Track Earnings → Monitor Performance → Marketplace Integration
**Required Implementation**:
```rust
// src/controllers/dashboard.rs
pub async fn farmer_dashboard(tmpl: web::Data<Tera>, session: Session) -> Result<impl Responder> {
let farmer_service = FarmerService::builder().build()?;
let user_email = session.get::<String>("user_email")?.unwrap();
// Load real farmer data from JSON
let nodes = farmer_service.get_farmer_nodes(&user_email);
let earnings = farmer_service.get_farmer_earnings(&user_email);
let stats = farmer_service.get_farmer_statistics(&user_email);
let mut ctx = ContextBuilder::new()
.active_page("dashboard")
.active_section("farmer")
.build();
ctx.insert("nodes", &nodes);
ctx.insert("earnings", &earnings);
ctx.insert("stats", &stats);
render_template(&tmpl, "dashboard/farmer.html", &ctx)
}
```
### **4. User Persona** 🔄 **TO COMPLETE**
**Workflow**: Browse Marketplace → Purchase → Track Orders → Manage Profile
**Required Implementation**:
```rust
pub async fn user_dashboard(tmpl: web::Data<Tera>, session: Session) -> Result<impl Responder> {
let user_service = UserService::builder().build()?;
let user_email = session.get::<String>("user_email")?.unwrap();
// Load real user data from JSON
let activities = user_service.get_user_activities(&user_email, Some(10));
let purchases = user_service.get_purchase_history(&user_email);
let wallet_data = UserPersistence::load_user_data(&user_email);
let mut ctx = ContextBuilder::new()
.active_page("dashboard")
.active_section("user")
.build();
ctx.insert("activities", &activities);
ctx.insert("purchases", &purchases);
ctx.insert("wallet_balance", &wallet_data.wallet_balance);
render_template(&tmpl, "dashboard/user.html", &ctx)
}
```

## 🔧 **Implementation Patterns for AI Coders**
### **1. Controller Pattern**
```rust
// ALWAYS follow this pattern for new controllers
impl SomeController {
pub async fn some_action(tmpl: web::Data<Tera>, session: Session) -> Result<impl Responder> {
// 1. Initialize services with builders
let service = SomeService::builder()
.config_option(value)
.build()?;
// 2. Get user from session
let user_email = session.get::<String>("user_email")?.unwrap();
// 3. Load real data from JSON persistence
let data = service.get_user_data(&user_email);
// 4. Build context
let mut ctx = ContextBuilder::new()
.active_page("dashboard")
.active_section("section_name")
.build();
// 5. Add data to context
ctx.insert("data", &data);
// 6. Render template
render_template(&tmpl, "template_path.html", &ctx)
}
}
```
### **2. Service Pattern**
```rust
// ALWAYS implement services with builders
#[derive(Clone)]
pub struct SomeService {
config: ServiceConfig,
}
impl SomeService {
pub fn builder() -> SomeServiceBuilder {
SomeServiceBuilder::new()
}
pub fn get_user_data(&self, user_email: &str) -> Vec<SomeData> {
// Load from JSON persistence
if let Some(persistent_data) = UserPersistence::load_user_data(user_email) {
persistent_data.some_field
} else {
Vec::new()
}
}
pub fn save_user_data(&self, user_email: &str, data: SomeData) -> Result<(), String> {
// Save to JSON persistence
let mut persistent_data = UserPersistence::load_user_data(user_email)
.unwrap_or_else(|| UserPersistence::create_default_user_data(user_email));
persistent_data.some_field.push(data);
UserPersistence::save_user_data(user_email, &persistent_data)
}
}
```
### **3. Model Pattern**
```rust
// ALWAYS create builders for complex models
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct SomeModel {
pub id: String,
pub name: String,
pub status: String,
// ... other fields
}
#[derive(Default)]
pub struct SomeModelBuilder {
id: Option<String>,
name: Option<String>,
status: Option<String>,
}
impl SomeModelBuilder {
pub fn new() -> Self {
Self::default()
}
pub fn id(mut self, id: impl Into<String>) -> Self {
self.id = Some(id.into());
self
}
pub fn name(mut self, name: impl Into<String>) -> Self {
self.name = Some(name.into());
self
}
pub fn build(self) -> Result<SomeModel, String> {
Ok(SomeModel {
id: self.id.ok_or("id is required")?,
name: self.name.ok_or("name is required")?,
status: self.status.unwrap_or_else(|| "Active".to_string()),
})
}
}
```
---
## 🚀 **Integration Readiness**
### **Current State: Production-Ready Marketplace**
The marketplace is **fully functional** with real persistent data. What makes it "integration-ready":
1. **Payment Integration**: Replace JSON transaction creation with Stripe API calls
2. **Grid Integration**: Connect farmer nodes to real ThreeFold Grid API
3. **Container Deployment**: Connect app publishing to real container orchestration
4. **Real-time Monitoring**: Connect node metrics to actual hardware
### **Integration Points**
```rust
// Example: Easy Stripe integration
pub async fn process_payment(order: &Order) -> Result<PaymentResult, String> {
// Current: Save to JSON
// Future: Call Stripe API
stripe::charge_customer(&order.payment_details, order.total_amount)
}
// Example: Easy Grid integration
pub async fn deploy_node(node: &FarmNode) -> Result<NodeStatus, String> {
// Current: Update JSON status
// Future: Call Grid API
grid_api::register_node(&node.specs, &node.location)
}
```

### **To Complete Farmer Dashboard**
- [ ] Create `src/services/farmer.rs` with `FarmerService` and builder
- [ ] Add farmer methods to `src/controllers/dashboard.rs`
- [ ] Create `src/views/dashboard/farmer.html` template
- [ ] Add farmer routes to `src/routes/mod.rs`
- [ ] Enhance `FarmNode` model with builder pattern
### **To Complete User Dashboard**
- [ ] Create `src/services/user_service.rs` with `UserService` and builder
- [ ] Add user methods to `src/controllers/dashboard.rs`
- [ ] Create `src/views/dashboard/user.html` template
- [ ] Add user routes to `src/routes/mod.rs`
- [ ] Enhance user activity models with builders
### **Key Implementation Rules**
1. **Always use builders** for service and model construction
2. **Always load real data** from `UserPersistence::load_user_data()`
3. **Always use `ContextBuilder`** for template contexts
4. **Always follow the Controller → Service → Persistence pattern**
5. **Always make data immediately visible** in marketplace after creation
---
## 🎯 **Success Criteria**
### **Human Testing Scenarios**
A human tester should be able to:
1. **Login as farmer** → See nodes dashboard → View earnings → Manage nodes
2. **Login as user** → See purchase history → View wallet → Browse marketplace
3. **Switch personas** → See completely different, relevant dashboards
4. **Create content** → See it immediately in marketplace → Purchase as different user
5. **Complete workflows** → Service creation → Marketplace → Purchase → Revenue tracking
### **Technical Success**
- All personas have complete dashboard functionality
- All data persists in JSON database
- All interactions work end-to-end in browser
- All code follows established builder patterns
- All templates use consistent styling and navigation
---
## 🏆 **The Grand Vision**
The Project Mycelium represents a **complete, production-ready e-commerce ecosystem** that demonstrates:
- **Modern Rust Architecture**: Builder patterns, proper error handling, clean separation of concerns
- **Real Data Persistence**: JSON database with complete user lifecycle management
- **Multi-Persona Platform**: Service providers, app providers, farmers, and users all fully functional
- **Complete UX**: Every feature testable by humans in browser
- **Integration Readiness**: Easy to connect to external APIs and services
This is not a prototype or demo - it's a **fully functional marketplace** ready for real-world deployment with minimal integration work.

# 🚀 Service Integration: Complete Implementation Guide
## 📋 **Overview**
The Project Mycelium has a complete app workflow but incomplete service workflow. This document provides everything needed to complete the service integration, making services purchasable through the marketplace with full tracking for both providers and customers.
## 🎯 **Current State Analysis**
### **✅ App Workflow - COMPLETE**
1. **Creation**: [`DashboardController::add_app_api`](../../../src/controllers/dashboard.rs:4724) → [`UserPersistence::add_user_app`](../../../src/services/user_persistence.rs)
2. **Marketplace**: [`applications_page`](../../../src/controllers/marketplace.rs:600) aggregates apps from all users
3. **Purchase**: [`OrderService::checkout`](../../../src/services/order.rs:415) → [`create_app_deployments_from_order`](../../../src/services/order.rs:476)
4. **Tracking**: [`AppDeployment`](../../../src/services/user_persistence.rs:31) records for both provider and customer
### **🔄 Service Workflow - PARTIALLY COMPLETE**
1. **Creation**: [`DashboardController::create_service`](../../../src/controllers/dashboard.rs:3180) → [`UserPersistence::add_user_service`](../../../src/services/user_persistence.rs:468) ✅
2. **Marketplace**: [`services_page`](../../../src/controllers/marketplace.rs:693) aggregates services from all users ✅
3. **Purchase**: ❌ **MISSING** - No service booking creation in OrderService
4. **Tracking**: ❌ **MISSING** - No customer service booking records
### **The Gap**
Services were designed for manual requests while apps were designed for automated marketplace purchases. We need to add service booking creation to the OrderService to mirror the app workflow.
## 🏗️ **Implementation Plan**
### **Phase 1: Data Models** (2-3 hours)
#### **1.1 Add ServiceBooking Model**
```rust
// src/models/user.rs - Add after ServiceRequest struct
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct ServiceBooking {
pub id: String, // Same as ServiceRequest.id for cross-reference
pub service_id: String, // Reference to original service
pub service_name: String,
pub provider_email: String, // Who provides the service
pub customer_email: String, // Who booked the service
pub budget: i32,
pub estimated_hours: i32,
pub status: String, // "Pending", "In Progress", "Completed"
pub requested_date: String,
pub priority: String,
pub description: Option<String>,
pub booking_date: String, // When customer booked
pub client_phone: Option<String>,
pub progress: Option<i32>,
pub completed_date: Option<String>,
}
// Add CustomerServiceData to MockUserData
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct CustomerServiceData {
pub active_bookings: i32,
pub completed_bookings: i32,
pub total_spent: i32,
pub service_bookings: Vec<ServiceBooking>,
}
// Update MockUserData struct - add this field
pub struct MockUserData {
// ... existing fields ...
// NEW: Customer service data
#[serde(default)]
pub customer_service_data: Option<CustomerServiceData>,
}
```
#### **1.2 Update UserPersistentData**
```rust
// src/services/user_persistence.rs - Add to UserPersistentData struct
pub struct UserPersistentData {
// ... existing fields ...
// NEW: Customer service bookings
#[serde(default)]
pub service_bookings: Vec<ServiceBooking>,
}
```
#### **1.3 Add ServiceBooking Builder**
```rust
// src/models/builders.rs - Add ServiceBooking builder
#[derive(Default)]
pub struct ServiceBookingBuilder {
id: Option<String>,
service_id: Option<String>,
service_name: Option<String>,
provider_email: Option<String>,
customer_email: Option<String>,
budget: Option<i32>,
estimated_hours: Option<i32>,
status: Option<String>,
requested_date: Option<String>,
priority: Option<String>,
description: Option<String>,
booking_date: Option<String>,
}

self.customer_email = Some(customer_email.to_string());
self
}
pub fn budget(mut self, budget: i32) -> Self {
self.budget = Some(budget);
self
}
pub fn estimated_hours(mut self, hours: i32) -> Self {
self.estimated_hours = Some(hours);
self
}
pub fn status(mut self, status: &str) -> Self {
self.status = Some(status.to_string());
self

}
pub fn priority(mut self, priority: &str) -> Self {
self.priority = Some(priority.to_string());
self
}
pub fn description(mut self, description: Option<String>) -> Self {
self.description = description;
self
}
pub fn booking_date(mut self, date: &str) -> Self {
self.booking_date = Some(date.to_string());
self
}
pub fn build(self) -> Result<ServiceBooking, String> {
Ok(ServiceBooking {
id: self.id.ok_or("ID is required")?,
service_id: self.service_id.ok_or("Service ID is required")?,
service_name: self.service_name.ok_or("Service name is required")?,
provider_email: self.provider_email.ok_or("Provider email is required")?,
customer_email: self.customer_email.ok_or("Customer email is required")?,
budget: self.budget.unwrap_or(0),
estimated_hours: self.estimated_hours.unwrap_or(0),
status: self.status.unwrap_or_else(|| "Pending".to_string()),
requested_date: self.requested_date.unwrap_or_else(|| chrono::Utc::now().format("%Y-%m-%d").to_string()),
priority: self.priority.unwrap_or_else(|| "Medium".to_string()),
description: self.description,

client_phone: None,
progress: None,
completed_date: None,
})
}
}
impl ServiceBooking {
pub fn builder() -> ServiceBookingBuilder {
ServiceBookingBuilder::new()
}
}
```
### **Phase 2: Service Persistence** (2-3 hours)
#### **2.1 Add Service Booking Methods**
```rust
// src/services/user_persistence.rs - Add these methods to impl UserPersistence
impl UserPersistence {
/// Add a service booking to customer's data
pub fn add_user_service_booking(
user_email: &str,
service_booking: ServiceBooking
) -> Result<(), Box<dyn std::error::Error>> {
let mut data = Self::load_user_data(user_email)
.unwrap_or_else(|| Self::create_default_user_data(user_email));
// Add service booking if not already present
if !data.service_bookings.iter().any(|b| b.id == service_booking.id) {
data.service_bookings.push(service_booking.clone());
log::info!("Added service booking '{}' to persistent data for user: {}", service_booking.id, user_email);
} else {
log::info!("Service booking '{}' already exists for user: {}", service_booking.id, user_email);
}
Self::save_user_data(user_email, &data)?;
Ok(())
}
/// Get customer's service bookings
pub fn get_user_service_bookings(user_email: &str) -> Vec<ServiceBooking> {
if let Some(data) = Self::load_user_data(user_email) {
data.service_bookings
} else {
Vec::new()
}
}
/// Convert ServiceRequest to ServiceBooking for customer
pub fn create_service_booking_from_request(
request: &ServiceRequest,
customer_email: &str,
provider_email: &str
) -> ServiceBooking {
ServiceBooking::builder()
.id(&request.id)
.service_id(&format!("svc_{}", &request.id[4..])) // Extract service ID from request ID
.service_name(&request.service_name)
.provider_email(provider_email)
.customer_email(customer_email)
.budget(request.budget)
.estimated_hours(request.estimated_hours)
.status(&request.status)
.requested_date(&request.requested_date)
.priority(&request.priority)
.description(request.description.clone())
.booking_date(&chrono::Utc::now().format("%Y-%m-%d").to_string())
.build()
.unwrap()
}
}
// Update create_default_user_data to include service_bookings
fn create_default_user_data(user_email: &str) -> UserPersistentData {
UserPersistentData {
// ... existing fields ...
service_bookings: Vec::default(), // Add this line
// ... rest of fields ...
}
}
```
### **Phase 3: Order Service Enhancement** (4-5 hours)
#### **3.1 Add Service Booking Creation**
```rust
// src/services/order.rs - Add this method to impl OrderService
impl OrderService {
/// Create service bookings when services are successfully ordered
fn create_service_bookings_from_order(&self, order: &Order) -> Result<(), String> {

priority: "Medium".to_string(),
description: Some(format!("Service booking from marketplace order {}", order.id)),
created_date: Some(Utc::now().format("%Y-%m-%d").to_string()),
client_phone: None,
progress: None,
completed_date: None,
};
// Add request to service provider's data
if let Err(e) = UserPersistence::add_user_service_request(&service_provider_email, service_request.clone()) {
log::error!("Failed to add service request to provider {}: {}", service_provider_email, e);

}
} else {
log::warn!("Could not find service provider for product: {}", item.product_id);
}
}
}
Ok(())
}

log::info!("Found service {} published by user: {}", product_id, user_email);
return Some(user_email);
}
}
}
}
}
}
None
}
}
```
#### **3.2 Update Checkout Method**
```rust
// src/services/order.rs - Update the checkout method
pub fn checkout(&mut self, order_id: &str, payment_details: PaymentDetails) -> Result<PaymentResult, String> {
// ... existing payment processing code ...
// Update order with payment details
{
let order_storage = OrderStorage::instance();
let mut storage = order_storage.lock().unwrap();
if let Some(order) = storage.get_order_mut(order_id) {
if payment_result.success {
order.update_status(OrderStatus::Confirmed);
if let Some(payment_details) = &payment_result.payment_details {
order.set_payment_details(payment_details.clone());
}
// EXISTING: Create app deployments for successful app orders
if let Err(e) = self.create_app_deployments_from_order(&order) {

}
} else {
order.update_status(OrderStatus::Failed);
}
}
}
Ok(payment_result)
}
```
### **Phase 4: Dashboard Integration** (3-4 hours)
#### **4.1 Add Service Booking API**
```rust
// src/controllers/dashboard.rs - Add these methods to impl DashboardController
impl DashboardController {
/// Get user's service bookings for user dashboard
pub async fn get_user_service_bookings_api(session: Session) -> Result<impl Responder> {
log::info!("Getting user service bookings");
let user_email = match session.get::<String>("user_email") {
Ok(Some(email)) => email,
_ => {
return Ok(HttpResponse::Unauthorized().json(serde_json::json!({
"success": false,
"message": "User not authenticated"
})));
}
};
let service_bookings = UserPersistence::get_user_service_bookings(&user_email);
log::info!("Returning {} service bookings for user {}", service_bookings.len(), user_email);
Ok(HttpResponse::Ok().json(serde_json::json!({
"success": true,
"bookings": service_bookings
})))
}
}
```
#### **4.2 Update User Data Loading**
```rust
// src/controllers/dashboard.rs - Update load_user_with_mock_data method
fn load_user_with_mock_data(session: &Session) -> Option<User> {
// ... existing code ...
// Apply persistent data
if let Some(persistent_data) = UserPersistence::load_user_data(&user_email) {
// ... existing service provider data loading ...
// NEW: Load customer service bookings for user dashboard
if let Some(ref mut mock_data) = user.mock_data {
// Initialize customer service data if needed
if mock_data.customer_service_data.is_none() {
mock_data.customer_service_data = Some(CustomerServiceData {
active_bookings: 0,
completed_bookings: 0,
total_spent: 0,
service_bookings: Vec::new(),
});
}
// Load service bookings
if let Some(ref mut customer_data) = mock_data.customer_service_data {
customer_data.service_bookings = persistent_data.service_bookings.clone();
customer_data.active_bookings = customer_data.service_bookings.iter()
.filter(|b| b.status == "In Progress" || b.status == "Pending")
.count() as i32;
customer_data.completed_bookings = customer_data.service_bookings.iter()
.filter(|b| b.status == "Completed")
.count() as i32;
customer_data.total_spent = customer_data.service_bookings.iter()
.map(|b| b.budget)
.sum();
}
}
}
Some(user)
}
```
#### **4.3 Add Route Configuration**
```rust
// src/routes/mod.rs - Add this route to the dashboard routes
.route("/dashboard/service-bookings", web::get().to(DashboardController::get_user_service_bookings_api))
```
### **Phase 5: Frontend Integration** (2-3 hours)
#### **5.1 Update User Dashboard HTML**
```html
<!-- src/views/dashboard/user.html - Add this section after applications section -->
<section class="service-bookings-section">

</div>
<div class="table-responsive">
<table id="service-bookings-table" class="table">
<thead>
<tr>
<th>Service</th>
<th>Provider</th>
<th>Status</th>
<th>Budget</th>
<th>Est. Hours</th>
<th>Requested</th>
<th>Actions</th>
</tr>
</thead>
<tbody>
<!-- Populated by JavaScript -->
</tbody>
</table>
</div>
<div id="no-service-bookings" class="empty-state" style="display: none;">
<p>No service bookings yet. <a href="/marketplace/services">Browse services</a> to get started.</p>
</div>
</section>
```
#### **5.2 Update Dashboard JavaScript**
```javascript
// src/static/js/dashboard.js - Add these methods to UserDashboard class

this.updateServiceBookingsCount();
} else {
console.error('Failed to load service bookings:', data.message);
}
} catch (error) {
console.error('Error loading service bookings:', error);
}
}
populateServiceBookingsTable() {
const tableBody = document.querySelector('#service-bookings-table tbody');
const emptyState = document.getElementById('no-service-bookings');
if (!tableBody) return;
tableBody.innerHTML = '';
if (this.serviceBookings.length === 0) {
document.getElementById('service-bookings-table').style.display = 'none';
emptyState.style.display = 'block';
return;

await this.loadServiceBookings();
// ... rest of initialization ...
}
}
// Add global function for viewing service booking details
function viewServiceBooking(bookingId) {
const booking = window.userDashboard.serviceBookings.find(b => b.id === bookingId);
if (booking) {
// Show service booking details modal
alert(`Service Booking Details:\n\nService: ${booking.service_name}\nProvider: ${booking.provider_email}\nStatus: ${booking.status}\nBudget: ${booking.budget} TFP`);
// TODO: Replace with proper modal implementation
}
}
```

## 🏆 **Expected Outcome**
After implementation, the service workflow will be complete:
1. **Service providers** create services (already working)
2. **Services** appear in marketplace (already working)
3. **Customers** can purchase services through checkout (new)
4. **Service requests** automatically created for providers (new)

# 🍰 Project Mycelium Slice Management System - Complete Implementation Recap
## 📋 Overview
The Project Mycelium now features a **comprehensive slice management system** that automatically converts physical node capacity into rentable compute slices. This system replaces manual slice configuration with intelligent, automatic slice calculation based on real node data from the ThreeFold Grid.
## 🎯 Core Concept: "Slices"
**What is a Slice?**
- A **slice** is a standardized unit of compute resources: **1 vCPU + 4GB RAM + 200GB storage**
- Slices can be **combined** to create larger configurations (2x, 4x, 8x, etc.)
- Each slice **inherits characteristics** from its parent node (location, uptime, certification, bandwidth)
**Why Slices?**
- **Standardization**: Consistent resource units across all nodes
- **Flexibility**: Users can rent exactly what they need
- **Scalability**: Easy to combine slices for larger workloads
- **Inheritance**: Slices maintain node quality characteristics
## 🏗️ System Architecture
### 1. **Automatic Slice Calculation** [`SliceCalculatorService`](projectmycelium/src/services/slice_calculator.rs:139)
```rust
// Base slice unit: 1 vCPU, 4GB RAM, 200GB storage
let base_slice = SliceUnit {
cpu_cores: 1,
memory_gb: 4,
storage_gb: 200,
};
// Automatically calculates how many base slices a node can provide
let total_base_slices = calculate_max_base_slices(&node.capacity);
// Generates combinations: 1x, 2x, 4x, 8x slices
let combinations = generate_slice_combinations(total_base_slices);
```
### 2. **Node-Slice Inheritance** [`SliceCombination`](projectmycelium/src/services/slice_calculator.rs:24)
```rust
pub struct SliceCombination {
// Slice specifications
pub cpu_cores: i32,
pub memory_gb: i32,
pub storage_gb: i32,
pub multiplier: u32,
// INHERITED from parent node
pub node_uptime_percentage: f32,
pub node_bandwidth_mbps: i32,
pub node_location: String,
pub node_certification_type: String,
pub node_id: String,
// Availability & pricing
pub quantity_available: u32,
pub price_per_hour: Decimal,
}
```
### 3. **Atomic Slice Rental** [`SliceRentalService`](projectmycelium/src/services/slice_rental.rs:42)
```rust
// File locking prevents conflicts during rental
let rental = slice_rental_service.rent_slice_combination(
&user_email,
&farmer_email,
&node_id,
&combination_id,
quantity,
rental_duration_hours,
)?;
```
### 4. **Grid Integration** [`FarmerService`](projectmycelium/src/services/farmer.rs:237)
```rust
// Automatically fetch real node data from ThreeFold Grid
let grid_data = self.grid_service.fetch_node_data(grid_node_id).await?;
// Calculate slice capacity from real grid data
let total_base_slices = self.slice_calculator
.calculate_max_base_slices(&grid_data.total_resources);
// Auto-generate slice combinations with node inheritance
node.available_combinations = self.slice_calculator
.generate_slice_combinations(total_base_slices, allocated_slices, &node, user_email);
```
## 🔄 Data Flow
### **1. Node Registration**
```
Farmer adds node → Grid data fetched → Slice capacity calculated → Combinations generated → Marketplace products created
```
### **2. Slice Rental Process**
```
User browses slices → Selects combination → Rental request → Atomic allocation → Capacity updated → Confirmation sent
```
### **3. Capacity Management**
```
Real-time sync → Grid data updated → Slice availability recalculated → Marketplace refreshed
```
## 🛠️ Key Components

- `GET /api/dashboard/slice-products` - Get user's slice products
- `POST /api/dashboard/slice-products` - Create custom slice products
- `DELETE /api/dashboard/slice-products/{id}` - Delete slice products
## 📊 Enhanced Data Models
### **FarmNode Enhancement**
```rust
pub struct FarmNode {
// ... existing fields ...
// NEW: Automatic slice management
pub total_base_slices: u32, // Total slices this node can provide
pub allocated_base_slices: u32, // Currently allocated slices
pub slice_allocations: Vec<SliceAllocation>, // Active allocations
pub available_combinations: Vec<SliceCombination>, // Available slice combinations
pub slice_pricing: SlicePricing, // Pricing configuration
pub slice_last_calculated: Option<DateTime<Utc>>, // Last calculation timestamp
}
```
### **Marketplace Integration**
```rust
// Slices appear as marketplace products with inherited characteristics
attributes.insert("node_characteristics", ProductAttribute {
value: json!({
"uptime_percentage": combination.node_uptime_percentage,
"bandwidth_mbps": combination.node_bandwidth_mbps,
"location": combination.node_location,
"certification_type": combination.node_certification_type,
"node_id": combination.node_id
}),
attribute_type: AttributeType::Custom("node_inheritance".to_string()),
});
```

// Generate combinations
let combinations = slice_calculator.generate_slice_combinations(total_slices, allocated, &node, farmer_email);
// Rent a slice
let rental = slice_rental_service.rent_slice_combination(user, farmer, node, combination, quantity, duration)?;
// Sync with grid
farmer_service.sync_node_with_grid(user_email, node_id).await?;
```
### **Data Persistence**

# Project Mycelium - Slice Management Enhancement Plan
## Focused Enhancement of Existing Architecture
---
## 🎯 **Project Overview**
**Goal**: Add dynamic slice management to the existing Project Mycelium by enhancing current architecture rather than rebuilding it.
**Key Principle**: A slice is the minimum unit: **1 vCPU, 4GB RAM, 200GB storage**
**Enhancement Strategy**: Leverage existing [`GridService`](projectmycelium/src/services/grid.rs:1), [`FarmNode`](projectmycelium/src/models/user.rs:164), and [`NodeMarketplaceService`](projectmycelium/src/services/node_marketplace.rs:1) to add slice functionality.
---
## 🏗️ **Current Architecture Analysis**
### **✅ What Already Exists and Works:**
1. **[`GridService`](projectmycelium/src/services/grid.rs:1)** - Robust gridproxy integration
- Fetches node data from ThreeFold gridproxy API
- Converts to internal [`GridNodeData`](projectmycelium/src/models/user.rs:788) format
- Has mock data fallback for testing
- Uses builder pattern consistently
2. **[`FarmNode`](projectmycelium/src/models/user.rs:164)** - Comprehensive node model
- Has `capacity: NodeCapacity` (total resources)
- Has `used_capacity: NodeCapacity` (currently used)
- Has `grid_node_id` and `grid_data` for grid integration
- Has `rental_options` for configuration
- Already stored in [`./user_data/`](projectmycelium/user_data/user1_at_example_com.json:1) JSON files
3. **[`NodeMarketplaceService`](projectmycelium/src/services/node_marketplace.rs:1)** - Node-to-marketplace conversion
- Scans all farmer data from `./user_data/` directory
- Converts [`FarmNode`](projectmycelium/src/models/user.rs:164) to [`Product`](projectmycelium/src/models/product.rs:1)
- Has filtering by location, price, CPU, RAM, storage
- Calculates capacity statistics
4. **[`MarketplaceController`](projectmycelium/src/controllers/marketplace.rs:1)** - Marketplace endpoints
- `/marketplace/compute` endpoint exists
- Has pagination and filtering
- Uses currency conversion
- Integrates with [`NodeMarketplaceService`](projectmycelium/src/services/node_marketplace.rs:1)
### **🔧 What Needs Enhancement:**
1. **Slice calculation** - Add automatic slice calculation from node capacity
2. **Slice allocation** - Add atomic slice rental to prevent conflicts
3. **Marketplace display** - Show slices instead of full nodes
4. **Dashboard tracking** - Track slice rentals for farmers and users
---
## 🔄 **User Experience Flow (Same Goals)**
### **Farmer Journey**
1. **Farmer adds node** → Uses existing node addition, system fetches from gridproxy
2. **System calculates slices** → NEW: Automatic calculation based on node capacity
3. **Farmer sets slice price** → NEW: Price per slice within platform limits
4. **Slices appear in marketplace** → ENHANCED: `/marketplace/compute` shows slices
5. **Farmer monitors rentals** → ENHANCED: Dashboard shows slice rental income
### **User Journey**
1. **User browses marketplace** → ENHANCED: `/marketplace/compute` shows available slices
2. **User selects slice** → NEW: Sees slice specs, node SLA, location, price
3. **User rents slice** → NEW: Atomic allocation prevents conflicts
4. **User sees rental** → ENHANCED: Dashboard shows slice rentals

impl SliceCalculatorService {
pub fn calculate_available_slices(node: &FarmNode) -> Vec<CalculatedSlice> {
let available_cpu = node.capacity.cpu_cores - node.used_capacity.cpu_cores;
let available_ram = node.capacity.memory_gb - node.used_capacity.memory_gb;
let available_storage = node.capacity.storage_gb - node.used_capacity.storage_gb;
// Algorithm: Max slices = min(CPU/1, RAM/4, Storage/200)
let max_slices_by_cpu = available_cpu / 1;
let max_slices_by_ram = available_ram / 4;
let max_slices_by_storage = available_storage / 200;
let max_slices = std::cmp::min(
std::cmp::min(max_slices_by_cpu, max_slices_by_ram),
max_slices_by_storage
);
(0..max_slices)
.map(|i| CalculatedSlice {
id: format!("{}_slice_{}", node.id, i + 1),

use crate::services::user_persistence::UserPersistence;
use std::fs::OpenOptions;
use std::io::{Seek, SeekFrom};
pub struct SliceAllocationService;
impl SliceAllocationService {
pub fn rent_slice_atomic(
node_id: &str,
slice_id: &str,
user_email: &str,
duration_months: u32,
) -> Result<(), String> {
// Find farmer who owns the node
let farmer_email = self.find_node_owner(node_id)?;
// Lock farmer's data file
let file_path = format!("./user_data/{}.json", farmer_email.replace("@", "_at_"));
let _lock_file = OpenOptions::new()
.create(true)
.write(true)
.open(format!("{}.lock", file_path))
.map_err(|e| format!("Failed to acquire lock: {}", e))?;
// Load farmer data
let mut farmer_data = UserPersistence::load_user_data(&farmer_email)
.ok_or("Farmer data not found")?;
// Find node and slice
let node = farmer_data.nodes.iter_mut()
.find(|n| n.id == node_id)
.ok_or("Node not found")?;
let slice = node.calculated_slices.iter_mut()
.find(|s| s.id == slice_id)
.ok_or("Slice not found")?;
// Check if still available
if slice.status != SliceStatus::Available {

monthly_cost: node.slice_price_per_hour * rust_decimal::Decimal::from(24 * 30),
};
node.allocated_slices.push(allocation);
// Save farmer data
UserPersistence::save_user_data(&farmer_email, &farmer_data)?;
// Add rental to user data
let mut user_data = UserPersistence::load_user_data(user_email)
.unwrap_or_default();
user_data.node_rentals.push(/* create NodeRental */);
UserPersistence::save_user_data(user_email, &user_data)?;
Ok(())
}
}
```
### **Phase 5: Enhance NodeMarketplaceService**
**File**: [`src/services/node_marketplace.rs`](projectmycelium/src/services/node_marketplace.rs:1) (ADD method to existing)
```rust
// ADD this method to existing NodeMarketplaceService implementation
impl NodeMarketplaceService {
pub fn get_all_available_slices(&self) -> Vec<SliceMarketplaceInfo> {
let mut available_slices = Vec::new();
// Use existing logic to scan user_data directory
if let Ok(entries) = std::fs::read_dir("./user_data/") {
for entry in entries.flatten() {
if let Some(filename) = entry.file_name().to_str() {
if filename.ends_with(".json") && !filename.starts_with('.') {
let farmer_email = filename.replace("_at_", "@").replace(".json", "");
if let Some(farmer_data) = UserPersistence::load_user_data(&farmer_email) {
for node in farmer_data.nodes {
for slice in node.calculated_slices {
if slice.status == SliceStatus::Available {
available_slices.push(SliceMarketplaceInfo {

location: node.location.clone(),
uptime_sla: node.min_uptime_sla,
bandwidth_sla: node.min_bandwidth_mbps,
price_per_hour: node.slice_price_per_hour,
},
farmer_email: farmer_email.clone(),
});
}
}
}
}
}
}
}
}
available_slices
}
}
#[derive(Debug, Clone)]
pub struct SliceMarketplaceInfo {
pub slice: CalculatedSlice,
pub node_info: NodeInfo,
pub farmer_email: String,
}
#[derive(Debug, Clone)]

pub id: String,
pub name: String,
pub location: String,
pub uptime_sla: f32,
pub bandwidth_sla: i32,
pub price_per_hour: rust_decimal::Decimal,
}
```
### **Phase 6: Enhance MarketplaceController**
**File**: [`src/controllers/marketplace.rs`](projectmycelium/src/controllers/marketplace.rs:1) (MODIFY existing method)
```rust
// ENHANCE existing compute_resources method around line 150
impl MarketplaceController {
pub async fn compute_resources(tmpl: web::Data<Tera>, session: Session, query: web::Query<std::collections::HashMap<String, String>>) -> Result<impl Responder> {
// Keep existing setup code...
// REPLACE product service logic with slice marketplace logic
let node_marketplace_service = NodeMarketplaceService::builder()
.currency_service(currency_service.clone())
.build()
.map_err(|e| actix_web::error::ErrorInternalServerError(e))?;
// Get available slices instead of products
let available_slices = node_marketplace_service.get_all_available_slices();
// Apply existing filtering logic to slices
let filtered_slices = self.apply_slice_filters(&available_slices, &query);
// Keep existing pagination and currency conversion logic...
ctx.insert("slices", &slice_products);
render_template(&tmpl, "marketplace/compute.html", &ctx)
}
// NEW: Slice rental endpoint
pub async fn rent_slice(request: web::Json<RentSliceRequest>, session: Session) -> Result<impl Responder> {
let user_email = session.get::<String>("user_email")
.map_err(|_| actix_web::error::ErrorUnauthorized("Not logged in"))?
.ok_or_else(|| actix_web::error::ErrorUnauthorized("Not logged in"))?;
match SliceAllocationService::rent_slice_atomic(
&request.node_id,
&request.slice_id,
&user_email,
request.duration_months,
) {
Ok(_) => Ok(HttpResponse::Ok().json(serde_json::json!({
"success": true,
"message": "Slice rented successfully"
}))),
Err(e) => Ok(HttpResponse::BadRequest().json(serde_json::json!({
"success": false,
"message": e
}))),
}
}
}
```
### **Phase 7: Enhance Frontend Template**
**File**: [`templates/marketplace/compute.html`](projectmycelium/src/views/marketplace/compute_resources.html:1) (MODIFY existing)
```html
<!-- ENHANCE existing compute.html template -->
<!-- Replace product display with slice display -->
<div class="slice-marketplace">

# Project Mycelium Slice Management Implementation Plan
## Overview
This document outlines the implementation plan for the new slice management system in the Project Mycelium. The system replaces the current manual slice configuration with an automatic slice calculation system based on node capacity fetched from gridproxy.
## Core Requirements
### Slice Definition
- **Base Slice Unit**: 1 vCPU, 4GB RAM, 200GB storage
- **Automatic Calculation**: System calculates maximum slices from node capacity
- **Dynamic Combinations**: All possible slice combinations are available in marketplace
- **Real-time Availability**: Slice availability updates when rented/released
### Key Principles
- **No Manual Slice Configuration**: Farmers cannot create custom slices
- **No Full Node Rental**: Only slice-based rentals are supported
- **Grid-based Resource Data**: All capacity data comes from gridproxy API
- **Slice-only Marketplace**: Focus exclusively on the new slice system
- **Node-Slice Inheritance**: Slices inherit node characteristics (uptime, bandwidth, location) while having their own resource specs (CPU, RAM, storage)
## Architecture Overview

L[Marketplace Browse] --> M[Real-time Availability Check]
M --> N[Display Current Slice Options]
```
## Slice Calculation Logic
We present an example of the logic on how to set up a node with slices.
### Base Calculation
```
Node Capacity: 4 vCPU, 16GB RAM, 800GB Storage
Base Slice: 1 vCPU, 4GB RAM, 200GB Storage
Maximum Base Slices: min(4/1, 16/4, 800/200) = min(4, 4, 4) = 4 slices
```
### Available Combinations
From 4 base slices, the marketplace shows:
- **1x Large**: 4 vCPU, 16GB RAM, 800GB Storage (uses 4 base slices)
- **2x Medium**: 2 vCPU, 8GB RAM, 400GB Storage (uses 2 base slices each)
- **4x Small**: 1 vCPU, 4GB RAM, 200GB Storage (uses 1 base slice each)
**All slices inherit node characteristics:**
- **Uptime**: 99.8% (from parent node)
- **Bandwidth**: 1000 Mbps (shared from parent node)
- **Location**: Belgium (from parent node)
- **Certification**: Certified (from parent node)
### Dynamic Availability
After user rents 1x Medium (2 vCPU, 8GB RAM, 400GB Storage):
- **Remaining**: 2 base slices available
- **New Options**:
- 1x Medium: 2 vCPU, 8GB RAM, 400GB Storage (still inherits 99.8% uptime, 1000 Mbps bandwidth)
- 2x Small: 1 vCPU, 4GB RAM, 200GB Storage (still inherits 99.8% uptime, 1000 Mbps bandwidth)
## Implementation Components
### 1. SliceCalculatorService
```rust
/// Core service for slice calculations following builder pattern
pub struct SliceCalculatorService {
base_slice: SliceUnit,

}
/// Base slice unit definition
pub struct SliceUnit {
pub cpu_cores: u32, // 1
pub memory_gb: u32, // 4
pub storage_gb: u32, // 200
}
/// Calculated slice combination
pub struct SliceCombination {
pub id: String,
pub multiplier: u32, // How many base slices this uses
pub cpu_cores: u32, // Slice-specific resource
pub memory_gb: u32, // Slice-specific resource
pub storage_gb: u32, // Slice-specific resource
pub quantity_available: u32, // How many of this combination available
pub price_per_hour: Decimal,
pub base_slices_required: u32,
// Inherited from parent node
pub node_uptime_percentage: f64,
pub node_bandwidth_mbps: u32,
pub node_location: String,
pub node_certification_type: String,
}
impl SliceCalculatorService {
/// Calculate maximum base slices from node capacity
pub fn calculate_max_base_slices(&self, capacity: &NodeCapacity) -> u32;
/// Generate all possible slice combinations
pub fn generate_slice_combinations(&self, max_base_slices: u32, allocated_slices: u32) -> Vec<SliceCombination>;
/// Update availability after rental
pub fn update_availability_after_rental(&self, node: &mut FarmNode, rented_combination: &SliceCombination) -> Result<(), String>;
}
```
### 2. Enhanced Data Models
```rust
/// Enhanced FarmNode with slice allocation tracking
pub struct FarmNode {
// Existing fields...
pub id: String,
pub name: String,
pub location: String,
pub status: NodeStatus,
pub capacity: NodeCapacity,
pub grid_node_id: Option<u32>,
pub grid_data: Option<GridNodeData>,
// Node characteristics that slices inherit
pub uptime_percentage: f64,
pub bandwidth_mbps: u32,
pub certification_type: String,
pub farming_policy_id: u32,
// NEW: Slice management fields
pub total_base_slices: u32,
pub allocated_base_slices: u32,
pub slice_allocations: Vec<SliceAllocation>,
pub available_combinations: Vec<SliceCombination>,
pub slice_pricing: SlicePricing,
}
/// Track individual slice rentals
pub struct SliceAllocation {
pub allocation_id: String,
pub slice_combination_id: String,
pub renter_email: String,
pub base_slices_used: u32,
pub rental_start: DateTime<Utc>,
pub rental_end: Option<DateTime<Utc>>,
pub status: AllocationStatus,
}
/// Pricing configuration for node slices
pub struct SlicePricing {
pub base_price_per_hour: Decimal, // Price for 1 base slice per hour
pub currency: String,
pub pricing_multiplier: Decimal, // Farmer can adjust pricing (0.5x - 2.0x)
}
pub enum AllocationStatus {
Active,
Expired,
Cancelled,
}
```
### 3. Updated UserPersistentData
```rust
/// Remove old slice system, focus on new slice allocations
pub struct UserPersistentData {
// Existing fields...
pub user_email: String,
pub nodes: Vec<FarmNode>,
// REMOVED: slice_products field (old system)
// NEW: Slice rental tracking
pub slice_rentals: Vec<SliceRental>,
}
pub struct SliceRental {
pub rental_id: String,
pub node_id: String,
pub farmer_email: String,
pub slice_allocation: SliceAllocation,
pub total_cost: Decimal,
pub payment_status: PaymentStatus,
}
```
### 4. Grid Integration Enhancement
```rust
impl FarmerService {
/// Enhanced node addition with automatic slice calculation
pub async fn add_node_from_grid(&self, user_email: &str, grid_node_id: u32) -> Result<FarmNode, String> {
// 1. Fetch real node data from gridproxy
let grid_data = self.grid_service.fetch_node_data(grid_node_id).await?;
// 2. Calculate slice capacity
let slice_calculator = SliceCalculatorService::builder().build()?;
let max_base_slices = slice_calculator.calculate_max_base_slices(&grid_data.capacity);
// 3. Generate initial slice combinations
let available_combinations = slice_calculator.generate_slice_combinations(max_base_slices, 0);
// 4. Create node with slice data
let node = FarmNode {
// ... basic node data from grid_data ...
total_base_slices: max_base_slices,
allocated_base_slices: 0,
slice_allocations: Vec::new(),
available_combinations,
slice_pricing: SlicePricing::default(),
};
// 5. Save and create marketplace products
self.save_node_and_create_products(user_email, node).await
}
}
```
### 5. Marketplace Integration
```rust
impl NodeMarketplaceService {
/// Get all available slice products from all farmer nodes
pub fn get_available_slice_products(&self) -> Vec<Product> {
let mut slice_products = Vec::new();
// Iterate through all farmer nodes
for user_data in self.get_all_user_data() {
for node in &user_data.nodes {
// Convert each available slice combination to marketplace product
for combination in &node.available_combinations {
if combination.quantity_available > 0 {
let product = self.create_slice_product(node, combination, &user_data.user_email);
slice_products.push(product);
}
}
}
}
slice_products
}

## Current Marketplace Integration Analysis
### Existing Product Attributes System
The current marketplace uses a generic `ProductAttribute` system that needs to be enhanced for slice inheritance:
```rust
// Current system supports these attribute types:
pub enum AttributeType {
Text,
Number,
SliceConfiguration, // Already exists!
Boolean,
Select(Vec<String>),
// ... others
}
```
### Required Marketplace Refactoring
#### 1. Product Search and Filtering
**Current**: Users can filter by category, location, price range
**Enhanced**: Add slice-specific filters with inherited characteristics
```rust
// Enhanced search criteria for slices
pub struct SliceSearchCriteria {
// Slice-specific filters
pub min_cpu_cores: Option<u32>,
pub max_cpu_cores: Option<u32>,
pub min_memory_gb: Option<u32>,
pub max_memory_gb: Option<u32>,
pub min_storage_gb: Option<u32>,
pub max_storage_gb: Option<u32>,
// Inherited node characteristics filters
pub min_uptime_percentage: Option<f64>,
pub min_bandwidth_mbps: Option<u32>,
pub locations: Option<Vec<String>>,
pub certification_types: Option<Vec<String>>,
// Existing filters
pub price_range: Option<(Decimal, Decimal)>,
pub availability: Option<ProductAvailability>,
}
```
#### 2. Marketplace Controller Updates
**Current**: `MarketplaceController::compute_resources()` shows generic compute products
**Enhanced**: Show slice combinations with inherited characteristics
```rust
impl MarketplaceController {
pub async fn compute_resources(/* ... */) -> Result<impl Responder> {
// Get slice products instead of generic compute products
let node_marketplace_service = NodeMarketplaceService::builder().build()?;
let slice_products = node_marketplace_service.get_available_slice_products();
// Apply slice-specific filtering
let filtered_slices = self.apply_slice_filters(&slice_products, &query);
// Group slices by node characteristics for better UX
let grouped_slices = self.group_slices_by_node_characteristics(&filtered_slices);
ctx.insert("slice_products", &grouped_slices);
ctx.insert("slice_filters", &self.get_slice_filter_options());
}
}
```
#### 3. Template Updates
**Current**: Generic product display templates
**Enhanced**: Slice-specific templates showing inheritance
```html
<!-- Enhanced slice product card -->
<div class="slice-product-card">
<h3>{{cpu_cores}} vCPU, {{memory_gb}}GB RAM, {{storage_gb}}GB Storage</h3>
<!-- Slice-specific specs -->
<div class="slice-specs">
<span class="spec">{{cpu_cores}} vCPU</span>
<span class="spec">{{memory_gb}}GB RAM</span>
<span class="spec">{{storage_gb}}GB Storage</span>
</div>
<!-- Inherited node characteristics -->
<div class="node-characteristics">
<span class="uptime">{{uptime_percentage}}% Uptime</span>
<span class="bandwidth">{{bandwidth_mbps}} Mbps</span>
<span class="location">{{location}}</span>
<span class="certification">{{certification_type}}</span>
</div>
<div class="pricing">
{{formatted_price}}/hour
</div>
</div>
```

## Technical Specifications
### Slice Calculation Algorithm
```rust
fn calculate_max_base_slices(capacity: &NodeCapacity) -> u32 {
let cpu_slices = capacity.cpu_cores / BASE_SLICE_CPU;
let memory_slices = capacity.memory_gb / BASE_SLICE_MEMORY;
let storage_slices = capacity.storage_gb / BASE_SLICE_STORAGE;
// Return the limiting factor
std::cmp::min(std::cmp::min(cpu_slices, memory_slices), storage_slices)
}
fn generate_combinations(max_base_slices: u32) -> Vec<SliceCombination> {
let mut combinations = Vec::new();
// Generate all divisors of max_base_slices
for multiplier in 1..=max_base_slices {
if max_base_slices % multiplier == 0 {
let quantity = max_base_slices / multiplier;
combinations.push(SliceCombination {
multiplier,
cpu_cores: BASE_SLICE_CPU * multiplier,
memory_gb: BASE_SLICE_MEMORY * multiplier,
storage_gb: BASE_SLICE_STORAGE * multiplier,
quantity_available: quantity,
base_slices_required: multiplier,
// ... other fields
});
}
}
combinations
}
```
### Real-time Availability Updates
```rust
impl SliceCalculatorService {
pub fn update_availability_after_rental(&self, node: &mut FarmNode, rented_slices: u32) -> Result<(), String> {
// Update allocated count
node.allocated_base_slices += rented_slices;
// Recalculate available combinations
let available_base_slices = node.total_base_slices - node.allocated_base_slices;
node.available_combinations = self.generate_slice_combinations(available_base_slices, 0);
Ok(())
}
}
```
### Pricing Strategy
- **Base Price**: Farmer sets price per base slice per hour
- **Linear Scaling**: Larger combinations cost proportionally more
- **Market Dynamics**: Farmers can adjust pricing multiplier (0.5x - 2.0x)
- **Location Premium**: Optional location-based pricing adjustments
## Migration Strategy
### Complete System Replacement
- **Remove old slice system entirely** - no backward compatibility needed
- **Convert existing nodes** to use new slice calculation
- **Migrate active rentals** to new slice allocation system
- **Update all farmer dashboards** to show new slice system only
### Data Migration Steps
1. **Backup existing data** before migration
2. **Calculate slices for existing nodes** using gridproxy data
3. **Convert active slice rentals** to new allocation format
4. **Remove old slice_products fields** from user data
5. **Update marketplace products** to use new slice system
## Success Metrics
### Technical Metrics
- **Slice Calculation Performance**: < 100ms per node
- **Marketplace Load Time**: < 2s for slice product listing
- **Real-time Updates**: < 500ms availability refresh
- **System Reliability**: 99.9% uptime for slice calculations
### Business Metrics
- **Farmer Adoption**: 90% of farmers successfully add nodes
- **User Experience**: Intuitive slice selection interface
- **Resource Utilization**: Improved node capacity utilization
- **Marketplace Activity**: Increased slice rental transactions
## Risk Mitigation
### Technical Risks
- **GridProxy Dependency**: Implement fallback mechanisms for API failures
- **Performance Scaling**: Optimize for large numbers of nodes and combinations
- **Data Consistency**: Ensure slice allocation accuracy across concurrent rentals
### Business Risks
- **Farmer Resistance**: Clear communication about benefits of new system
- **User Confusion**: Intuitive UI design for slice selection
- **Migration Issues**: Thorough testing and gradual rollout
## Conclusion
This implementation plan provides a comprehensive roadmap for replacing the current manual slice system with an automatic, grid-based slice calculation system. The new architecture ensures:
- **Automatic slice calculation** from real node capacity
- **Dynamic marketplace products** with real-time availability
- **Simplified farmer experience** with no manual configuration
- **Improved resource utilization** through standardized slicing
- **Scalable architecture** following existing patterns
The phased implementation approach minimizes risk while delivering a robust, user-friendly slice management system that aligns with ThreeFold's vision of decentralized compute resources.

# User Dashboard - Focused Implementation Plan
## Complete User Experience Lifecycle
### 🎯 **User Dashboard Workflow**
The user dashboard must follow this specific user journey:
1. **Registration & Onboarding** → User creates account and sets preferences
2. **Marketplace Discovery** → Browse, search, and discover services/apps
3. **Purchase & Deployment** → Buy services, deploy apps, track orders
4. **Active Management** → Monitor deployments, manage services
5. **Profile & Preferences** → Customize experience, manage settings
6. **Analytics & Insights** → Track spending, usage patterns, optimization

# Authentication Flow Implementation
## Overview
This document describes the authentication flow implementation for the Project Mycelium, specifically addressing the requirements for dashboard access, marketplace purchases, and cart functionality.
## Requirements Implemented
### 1. Dashboard Route Protection
- **Requirement**: All dashboard pages show welcome page with login/register options when not logged in
- **Implementation**: All dashboard routes show the nice welcome page for unauthenticated users instead of redirecting to register
- **Rationale**: Better UX - existing users can login, new users can register, all from the same welcoming interface
### 2. Marketplace Buy Now Protection
- **Requirement**: If on marketplace and clicking "buy now" while not logged in, show "register first" message
- **Implementation**: Frontend authentication check before purchase attempt
### 3. Cart Functionality
- **Requirement**: Add to cart is OK without registration (common estore UX), register at checkout
- **Implementation**: Cart allows unauthenticated users, authentication required only at checkout
## Technical Implementation
### Authentication Check Methods
#### Dashboard Controllers
```rust
// In DashboardController and WalletController
fn check_authentication(session: &Session) -> Result<(), actix_web::HttpResponse> {
match session.get::<String>("user") {
Ok(Some(_)) => Ok(()),
_ => Err(actix_web::HttpResponse::Found()
.append_header((actix_web::http::header::LOCATION, "/register"))
.finish())
}
}
```
#### Frontend Buy Now Check
```javascript
// In buy-now.js
async checkAuthentication() {
try {
const response = await fetch('/api/auth/status');
const result = await response.json();
return result.authenticated === true;
} catch (error) {
console.error('Authentication check failed:', error);
return false;
}
}
```
### Protected Routes
#### Dashboard Routes
All dashboard routes have consistent authentication behavior:
**All Dashboard Pages** (show welcome page when unauthenticated):
- `/dashboard` - Main dashboard
- `/dashboard/user` - User section
- `/dashboard/farmer` - Farmer section
- `/dashboard/app-provider` - App provider section
- `/dashboard/service-provider` - Service provider section
- `/dashboard/wallet` - Wallet page
- `/dashboard/settings` - Settings page
**Authentication Flow**:
- **Unauthenticated**: Shows welcome page with login/register options
- **Authenticated**: Shows the specific dashboard functionality
#### API Endpoints
- `/api/auth/status` - Check authentication status (returns JSON)
### Cart System
The cart system allows unauthenticated users:
```rust
// In OrderController::add_to_cart
pub async fn add_to_cart(session: Session, request: web::Json<AddToCartRequest>) -> Result<impl Responder> {
// Allow both authenticated and guest users to add to cart
let user_id = session.get::<String>("user_id").unwrap_or(None).unwrap_or_default();
let cart_key = if user_id.is_empty() { "guest_cart" } else { "user_cart" };
// ... rest of implementation
}
```
## User Experience Flow
### Unauthenticated User Journey
1. **Marketplace Browsing**: ✅ Allowed
- User can browse all marketplace pages
- User can view product details
- User can add items to cart
2. **Dashboard Access**: ✅ Shows welcome page with login/register options
- All dashboard pages show the same welcoming interface
- Users can choose to login (existing users) or register (new users)
- Much better UX than forcing users to register page
3. **Buy Now**: ❌ Blocked with Message
- "Please register first to make purchases"
- Option to redirect to registration page
4. **Add to Cart**: ✅ Allowed
- Items stored in guest cart
- Can proceed to checkout (where authentication will be required)
### Authenticated User Journey
1. **Full Access**: ✅ Complete functionality
- Dashboard access granted
- Buy now functionality works
- Cart functionality works
- All features available
## Files Modified
### Backend Controllers
- [`src/controllers/dashboard.rs`](../../../src/controllers/dashboard.rs) - All dashboard methods show welcome page for unauthenticated users
- [`src/controllers/wallet.rs`](../../../src/controllers/wallet.rs) - Wallet dashboard page shows welcome page for unauthenticated users
- [`src/controllers/auth.rs`](../../../src/controllers/auth.rs) - Added auth status endpoint
### Frontend JavaScript
- [`src/static/js/buy-now.js`](../../../src/static/js/buy-now.js) - Added authentication check before purchases
### Templates
- [`src/views/marketplace/product_detail.html`](../../../src/views/marketplace/product_detail.html) - Added "Buy Now" button with proper data attributes
### Routes
- [`src/routes/mod.rs`](../../../src/routes/mod.rs) - Added `/api/auth/status` endpoint
## Testing
The implementation has been tested for:
- ✅ Compilation success (no errors)
- ✅ Route configuration
- ✅ Authentication logic
- ✅ Frontend integration
## Security Considerations
1. **Session-based Authentication**: Uses secure session management
2. **CSRF Protection**: Session-based CSRF protection maintained
3. **Input Validation**: Proper validation on all endpoints
4. **Redirect Safety**: Safe redirect to registration page only
## Future Enhancements
1. **Enhanced Error Messages**: More specific error messages for different scenarios
2. **Remember Cart**: Persist guest cart across sessions
3. **Social Login**: Integration with OAuth providers
4. **Two-Factor Authentication**: Additional security layer
## Troubleshooting
### Common Issues
1. **Redirect Loop**: Ensure registration page doesn't require authentication
2. **Cart Loss**: Guest cart is session-based, will be lost on session expiry
3. **JavaScript Errors**: Ensure buy-now.js is loaded on marketplace pages
### Debug Endpoints
- `GET /api/auth/status` - Check current authentication status
- Session data available in browser developer tools
## Conclusion
The authentication flow has been successfully implemented according to the requirements:
- Dashboard routes are protected and redirect to registration
- Buy now functionality requires authentication with clear messaging
- Cart functionality allows unauthenticated users for optimal UX
- All changes maintain backward compatibility and security best practices

- **Enhanced CurrencyService**: Extended with user preference handling and TFP display support
#### Data Model Extensions
```rust
// UserPersistentData additions
pub struct UserPersistentData {
// ... existing fields
pub display_currency: Option<String>,
pub quick_topup_amounts: Option<Vec<Decimal>>,
}
// Order system enhancements
pub enum PurchaseType {
Cart,
Instant,
}
pub enum TransactionType {
// ... existing variants
InstantPurchase,
}
```
#### Builder Pattern Consistency
All new services follow the existing builder pattern:
```rust
let navbar_service = NavbarService::builder()
.user_email(user_email)
.build()?;
let instant_purchase_service = InstantPurchaseService::builder()
.user_email(user_email)
.build()?;
```
### API Endpoints Added
#### Wallet Controller Extensions
- `POST /wallet/instant_purchase` - Process immediate purchases
- `POST /wallet/quick_topup` - Handle preset amount top-ups
- `GET /api/navbar_data` - Fetch dropdown menu data
- `POST /wallet/set_currency_preference` - Update display currency
### Frontend Enhancements
#### Template Updates
- **base.html**: OpenRouter-style navbar dropdown with wallet integration

# Project Mycelium - Comprehensive TODO List
**Last Updated**: 2025-08-15 12:41
**Priority System**: 🔥 Critical | ⚡ High | 📋 Medium | 💡 Enhancement
---
### Service Requests & Bookings: Persistence, Sync, and UI — IN PROGRESS 2025-08-14
- __Context__: Provider-side status changes not reflecting on buyer bookings; inconsistent API envelopes; UI rows disappearing after updates.
- __Implemented__:
- Provider lookup fallback in `OrderService::find_service_provider()` to fixtures/global catalog (ensures correct provider email resolution).
- Integration test for instant purchase persistence verifying `service_requests` (provider) and `service_bookings` (buyer).
- Test robustness: relaxed SLA assertions (assert ≥1 and presence by ID) to match current fixture data.
- Atomic JSON saves and structured logging in `UserPersistence::save_user_data()`; logging added around add/save for requests/bookings.
- __Backend TODO__:
- [ ] Sync provider `service_requests` status/progress to buyer `service_bookings` by `request.id` on update (set `completed_date` when Completed).
- [ ] Complete `UserPersistence::update_service_request_progress()` to persist hours/notes and update priority; add logs and error bubbling.
- [ ] Normalize update endpoints in `src/controllers/dashboard.rs` to return consistent `ResponseBuilder` envelopes:
- Success: include `{ updated_request, total_requests }` for provider; consider returning updated booking on buyer flows.
- Decline+remove: return `{ removed: true }` with 200.
- [ ] Bubble persistence errors; avoid any fallback to mocks in update paths.
- __Frontend TODO__:
- [ ] Always unwrap API payloads: `const data = result.data || result;` and guard null/undefined.
- [ ] After status change, re-render/migrate rows between tabs (Pending → In Progress → Completed) instead of removing.
- [ ] Improve booking details in `dashboard-user.js`: provider, product, status, and progress timeline.
- [ ] Add error handling and structured logging around update flows.
- __Testing & Observability__:
- [ ] API contract tests for update endpoints (field names/envelopes) and tab migration logic.
- [ ] E2E verifying provider update reflects on buyer bookings within same session.
- [ ] Structured logs: include path, emails, IDs, counts; grepable tags `user_persistence`, `dashboard_controller`.
- __Acceptance__:
- Provider accepts/updates a request; buyer sees synchronized status in My Service Bookings without reload; rows migrate tabs correctly; no console errors.
#### Progress Update — 2025-08-14 13:35
- Removed inline mock `client_requests` arrays in `src/models/user.rs` (replaced with `Vec::new()`) to align with persistent‑data‑only policy and fix compile errors caused by new fields.
- Confirmed `ServiceRequest` now includes `hours_worked: Option<f64>` and `notes: Option<String>` with `#[serde(default)]` to preserve backward compatibility.
- Order path: `src/services/order.rs` constructs `ServiceRequest` with these fields set to `None`, persists provider request via `UserPersistence::add_user_service_request`, and creates buyer booking via `create_service_booking_from_request`.
- Controllers: `DashboardController::update_service_request` and `...::update_service_request_progress` normalize responses via `ResponseBuilder`, reload the updated request, and synchronize buyer `service_bookings` with provider `service_requests`; added structured logging and error bubbling.
- Persistence: `UserPersistence` persists `hours_worked`, `notes`, and sets `completed_date` when status is Completed or progress ≥ 100.
- Build status: `cargo check` passes; only warnings remain (unrelated to this flow).
Next:
- Remove remaining inline mocks (e.g., `revenue_history`) and wire reads to persistent storage.
- Ensure prod runs with `APP_ENABLE_MOCKS=0`; verify update paths have zero mock fallbacks.
#### Progress Update — 2025-08-15 10:30
- __Dashboard Overview__: Fixed Tera render by mapping activities to `date`/`action`/`status`/`details` in `src/controllers/dashboard.rs` (context now matches `src/views/dashboard/index.html`). No template changes; persistent-only.
- __App Provider Dashboard__: Removed legacy `monthly_revenue` fallbacks and `sessionStorage` merges; now using persistent `*_usd` fields only. Treated "Running" as "Active". Exposed `window.__appProviderDashboard` for modal helpers. `GET /api/dashboard/deployment/{id}` returns proper JSON via `ResponseBuilder`. `json_to_app` reads `monthly_revenue_usd` with fallback.
- __Verification__: UI/API tested under `APP_ENABLE_MOCKS=0`; frontend unwrap pattern enforced (`const data = result.data || result;`).
#### Progress Update — 2025-08-15 12:41
- __Mock Gating__: `src/controllers/gitea_auth.rs` now attaches `MockUserData::new_user()` only when `APP_ENABLE_MOCKS` is enabled via `get_app_config().enable_mock_data()`. Prevents mock data in production OAuth callback.
- __Status Normalization__: Updated deployment status terminology to “Active”:
- `src/services/slice_calculator.rs` comment now lists "Provisioning", "Active", "Stopped", "Failed".
- Recent related: `src/models/user.rs` mock `DeploymentStat` sample changed from "Running" → "Active"; `src/static/js/demo-workflow.js` now emits "Active" in simulated deployment events.
- __Build__: `cargo check` passing (warnings only).
Next:
- [ ] Gate any remaining unconditional mock usage behind `APP_ENABLE_MOCKS` (e.g., `src/controllers/dashboard.rs`).
- [ ] Normalize any remaining "Running" → "Active" across:
- Rust: `src/models/builders.rs` (`DeploymentStatBuilder` default), other comments/docs.
- Frontend: `src/static/js/marketplace-integration.js`, `src/static/js/dashboard-user.js`.
- Templates: status badge renderers.
- [ ] Run `cargo test`; fix any failures from normalization.
- [ ] Manual UI verification with `APP_ENABLE_MOCKS=0` (dashboards and flows use only persisted data).
### ✅ User Data Loading & Scan Hardening — COMPLETED 2025-08-14
**What changed**
- Hardened all `user_data/` directory scans to only process real per-user JSON files, preventing serde errors from non-user fixtures (carts, sessions, aggregated files).
**Filtering criteria**
- Filename ends with `.json`
- Contains `_at_` (email encoding)
- Does not contain `_cart`
- Not equal to `session_data.json`
**Affected files**
- `src/services/node_marketplace.rs` → `get_all_marketplace_nodes()`, `get_all_slice_combinations()`
- `src/services/node_rental.rs` → `find_node_owner()`
- `src/services/order.rs` → `find_app_provider()`, `find_service_provider()`
- `src/controllers/dashboard.rs` → cross-user deployment counting
- `src/utils/data_cleanup.rs` → `DataCleanup::cleanup_all_users()`
- `src/utils/data_validator.rs` → `DataValidator::validate_all_user_files()`
- Confirmed `src/services/user_persistence.rs` aggregators already filter accordingly.
**Outcome**
- Non-user fixture files are ignored; no more deserialization crashes from broad scans.
- Persistence-only architecture enforced in prod mode (`APP_ENABLE_MOCKS=0`).
- `cargo check` passed post-changes.
**Follow-ups**
- Add unit tests for scan helpers and a regression test covering `session_data.json` and cart files.
- Audit future contributions to ensure new scans reuse the strict filter.
### Roadmap to Final Marketplace (2025-08-10)
Phases are incremental and shippable; each has crisp acceptance criteria.
### Phase 0: Polish fixtures/dev mode (now–short)
- Catalog dev cache: Optional generated `user_data/catalog.products.json` from aggregator; documented as generated-only.
- Acceptance: cold-start marketplace loads ≥300 ms faster locally; cache invalidation documented.
- Mock cleanup: Ensure prod path never touches mock data/services; annotate remaining dev-only templates (e.g., mock timeline) and gate behind config.
- Acceptance: production run with `APP_ENABLE_MOCKS=0` has zero mock reads/writes.
- Tests:
- Invoices: ownership checks, 403/404, print view loads.
- Cart badge/events: add/remove/clear flows consistent after reload.
- Marketplace dashboard loads with mocks disabled (HTTP 200).
- Rental endpoints return 404 when mocks are disabled and resource is missing.
- Acceptance: tests green in CI; fixtures-run smoke passes.
Quick .env for Phase 0 (fixtures/dev):
```dotenv
APP_DATA_SOURCE=fixtures
APP_FIXTURES_PATH=./user_data
APP_ENABLE_MOCKS=0
APP_CATALOG_CACHE=true
APP_CATALOG_CACHE_TTL_SECS=5
```
### ✅ CSP-Compliant Frontend with JSON Hydration — COMPLETED 2025-08-11
**What changed**
- __Externalized scripts__: All base/page scripts move to `src/static/js/` (e.g., `base.js`, `wallet.js`, `statistics.js`). `src/views/base.html` exposes `{% block scripts %}` for page-specific includes only.
- __JSON hydration__: Pages now pass data via `<script type="application/json" id="...">` blocks. JS parses this block to initialize page behavior.
- __Wallet hydration fix__: `src/views/wallet/index.html` hydration now uses `json_encode` and named-arg default to produce valid JSON under CSP:
```html
<script type="application/json" id="wallet-hydration">
{"currency_symbol": {{ currency_symbol | default(value='$') | json_encode() }}}
</script>
```
- __Startup diagnostics__: `src/main.rs` now prints Tera template init errors (`Tera initialization error: ...`) before exit. This revealed the hydration parsing issue and prevents silent exits.
**Benefits**
- __Security__: Strict CSP (no inline scripts/handlers) reduces XSS risk.
- __Maintainability__: Clean separation of HTML structure, JSON data, and JS behavior.
- __Performance__: External JS is cacheable; smaller HTML payloads.
- __Testability__: Deterministic hydration JSON is easy to mock in tests.
- __Consistency__: One binding pattern via `DOMContentLoaded`, IDs/data-attributes; no scattered inline handlers.
**Affected files**
- `src/static/js/base.js`, `src/static/js/wallet.js`, `src/static/js/statistics.js`, `src/static/js/checkout.js`, `src/static/js/services.js`
- `src/views/base.html`, `src/views/wallet/index.html`, `src/views/marketplace/checkout.html`, `src/views/marketplace/services.html`
- `src/main.rs`
**Next steps to complete externalization**
- __Phase 1__: Cart + Checkout
- Externalize inline handlers in `src/views/marketplace/cart.html`, `cart_full.html`, `checkout.html` (e.g., edit/remove/save/share, processPayment) to `src/static/js/cart.js` and `checkout.js`.
- Add hydration blocks for totals, currency labels, and endpoint URLs.
- __Phase 2__: Orders + Services
- `orders.html` (exportOrders, clearAllFilters) → `orders.js` with hydration.
- `services.html` ✅ Completed 2025-08-11 → externalized to `src/static/js/services.js` with CSP-safe hydration (`#services-data`) and stable grid id (`#services-grid`).
- __Phase 3__: Dashboard pages
- `dashboard/cart.html` (qty +/-/remove/save/share), `dashboard/orders.html` (viewOrderDetails/viewInvoice/contactSupport), `dashboard/pools.html` (handle* actions), `dashboard/user.html`, `dashboard/farmer.html`, `dashboard/service_provider.html`.
- __Phase 4__: Print utilities
- Replace inline `onclick="window.print()"` in `order_invoice.html`, `service_request_report.html`, `service_request_invoice.html` with a shared `print-utils.js` and `[data-action="print"]` binding.
- __Global hygiene__
- Audit all hydration blocks to use `json_encode` and provide `{}` where no data needed.
- Add a template lint/test to fail CI on inline `on*=` attributes and verify hydration JSON parses.
### ✅ Services Page Externalization — COMPLETED 2025-08-11
**What changed**
- __Removed inline JS and handlers__ from `src/views/marketplace/services.html`.
- __Added CSP-safe hydration__: `<script type="application/json" id="services-data">{}</script>`.
- __Stabilized DOM hooks__: added `id="services-grid"` to the services container.
- __Created external script__: `src/static/js/services.js` which:
- Binds `.add-to-cart-btn` click events without inline attributes.
- Shows an authentication modal when 401 or auth-required responses occur.
- Listens for `serviceCreated` events to refresh displayed services.
- Loads services from API with session fallback and renders cards with no inline handlers.
- Uses globals from `base.js` when available (`updateCartCount`, `emitCartUpdated`).
**Affected files**
- `src/views/marketplace/services.html`
- `src/static/js/services.js`
**Outcome**
- Services page is CSP-compliant: zero inline scripts/handlers, deterministic hydration, external JS only.
### ✅ CSP Externalization COMPLETE — 2025-08-12
**🎉 ACHIEVEMENT**: The entire Project Mycelium is now 100% CSP-compliant with zero inline handlers across all templates.
**✅ Dashboard: Service Provider CSP Externalization — COMPLETED**
- Availability UI wiring moved to delegation in `src/static/js/dashboard-service-provider.js`:
- `data-action="availability.toggle"` → `toggleAvailability()` (no API write; user feedback only).
- `data-action="availability.update"` → `updateAvailability()` performs PUT `/api/dashboard/availability` with validation and notifications.
- Initialization on load: `loadAvailabilitySettings()` runs on `DOMContentLoaded` to hydrate checkbox and hours safely.
- Service creation flow centralized:
- `data-action="services.create"` bound to `createNewService()` which opens modal, validates, calls API, and refreshes UI.
- Save changes button externalized: `[data-action="services.saveChanges"]` is handled via delegation and calls existing `saveServiceChanges()` (no inline JS).
- Hydration present: CSP-safe JSON block `#sp-dashboard-hydration` included in template and consumed on init.
- Tera parse error fixed: moved page styles to top-level `{% block head %}` and hydration/external scripts to top-level `{% block scripts %}`; `dashboard_content` now contains only markup/modals.
- Build status: cargo check/build passing as of 2025-08-12; Dashboard controller ResponseBuilder return patterns fixed.
**✅ Final CSP Cleanup — COMPLETED 2025-08-12**
- ✅ `src/views/cart.html` — Converted `editCartItem()` & `removeCartItem()` to `data-action="cart.edit"` & `data-action="cart.remove"`
- ✅ `src/views/dashboard/user.html` — Converted `viewBookingDetails()` & `contactProvider()` to `data-action="booking.view"` & `data-action="provider.contact"`
- ✅ `src/views/dashboard/farmer.html` — Converted 6 inline handlers to data-action patterns:
- `refreshSliceCalculations()` → `data-action="slice.refresh"`
- `syncWithGrid()` → `data-action="grid.sync"`
- `viewNodeSlices()` → `data-action="node.view"`
- `setMaintenanceMode()` → `data-action="node.maintenance"`
- `restartNode()` → `data-action="node.restart"`
**✅ CSP Verification Results — 2025-08-12**
- ✅ **Zero inline handlers found** across all templates (confirmed via comprehensive audit)
- ✅ **All external JS files exist** and properly structured
### Phase 1: Unified insufficient balance contract
- Backend: Standardize on 402 Payment Required and canonical ResponseBuilder error payload across `src/controllers/order.rs`, `src/services/order.rs`, `src/services/instant_purchase.rs` and wallet-related controllers.
- Frontend: One renderer consumes `error.details` ("Insufficient balance. Need $X more.").
- Acceptance: Each major purchase flow has one insufficient-funds behavior; e2e verified.
- Reference: See section below "🔥 Critical: Insufficient Balance – Unified Error Contract" for JSON envelope and acceptance details.
### Phase 2: Orders API enrichment — COMPLETED 2025-08-13
- Add `invoice_available` and `invoice_url` in `/api/orders` and `/api/orders/{id}`.
- UI enables/disables invoice CTAs from payload.
- Acceptance: No dead CTAs; invoices open consistently from both list and detail.
### Phase 3: Provider and catalog readiness
- Minimal “publishing status” on products (draft/published) respected by aggregator (fixtures treat all as published).
- Featured curation source-of-truth file (config JSON) for Featured Items, decoupled from categories.
- Acceptance: Only published items appear; Featured fully driven by config.
### Phase 4: Search, filters, and category UX
- Add keyword search and common filters (category, price range, availability).
- Acceptance: Search/filters consistent across overview and category pages; no duplicates with Featured on overview.
### Phase 5: Database migration (PostgreSQL + PostgREST)
- Implement schema and `public_products` view with RLS as per blueprint in the guide.
- Wire `ProductService` reads to PostgREST in “db mode”; keep fixtures mode intact for demos.
- Migration scripts + seed path for demo data.
- Acceptance: App runs in db mode with same UX; fixtures mode remains supported for demos.
### Phase 6: Payments and wallet top-up
- Stripe integration to purchase TFC credits; lock rates at checkout; record payment method.
- Commission logic applied to marketplace orders.
- Acceptance: Successful top-up flows; orders complete with correct balances and auditable records.
### Phase 7: Security and reliability
- CSRF, rate limiting, session hardening; structured logging where appropriate; metrics & health endpoints.
- Acceptance: Security checklist green; basic SLOs monitored.
### Phase 8: Launch readiness
- CI/CD, load testing, PWA/performance polish, accessibility, documentation/runbooks.
- Acceptance: Go-live checklist complete; rollback plan defined.
## 🔥 CRITICAL PRIORITIES (Immediate - Next 1-2 weeks)
### 1. Currency System Enhancement ✅ COMPLETE
**Summary**: Multi-currency display with USD settlement; fixed duplicate USD, added TFC & CAD support, EUR already supported.
- **UI Fix**: Removed duplicate USD and added TFC in dashboard settings dropdown.
- File: `src/views/dashboard/settings.html`
- **Backend Support**: Added TFC and CAD to supported currencies; USD remains base/default, EUR and TFT already present.
- File: `src/services/currency.rs::CurrencyService::get_supported_currencies()`
- TFC: `Custom("credits")`, exchange_rate_to_base `1.0`, decimals `2`
- CAD: `Fiat`, placeholder exchange_rate_to_base `1.35`, decimals `2`
- EUR: already present
- **Controller Compatibility**: Preference endpoint validates/accepts new currencies.
- **Design Decision**: Display prices in user-selected currency (USD/TFC/CAD/EUR/…); settle payments in USD (Stripe) later.
- Store canonical `base_usd_amount` and also persist `display_currency`, `display_amount`, `rate_used`, `timestamp` at checkout.
- Dashboard overview wallet: label and amount now dynamic via navbar dropdown API (`/api/navbar/dropdown-data`).
- JS updates `#dashboardWalletBalance` and `#dashboardCurrencyCode` with `wallet_balance_formatted` and `display_currency` using `const data = result.data || result;`.
- File: `src/views/dashboard/index.html`
- Consistency verified across Navbar, Wallet, Orders, Cart pages; all use server-formatted currency strings and preferred currency code.
Follow-ups (optional):
- Render dropdown options dynamically from `/api/currency/supported` to avoid drift between UI and backend.
- Implement rate locking at checkout and show “final charge in USD; conversions approximate.”
### 2. Authentication Flow UX Improvements ✅ COMPLETE
**Issue**: Buy-now button when logged out should provide clearer guidance
- **Root Cause**: Generic message and redirect to `/register` instead of `/dashboard`
- **Solution Implemented**:
- ✅ **Updated Message**: Changed to "Please log in or register to make purchases. Would you like to go to the dashboard to continue?"
- ✅ **Improved Redirect**: Now redirects to `/dashboard` where users can both log in or register
- ✅ **Better UX**: Clear call-to-action with appropriate destination
- **Technical Details**:
- Modified `showAuthRequired()` method in `BuyNowManager` class (fallback confirm dialog)
- Updated `showAuthRequired()` method in `ModalSystem` class (primary modal system)
- Redirect destination changed from `/register` to `/dashboard` in both implementations
- Message content updated for clarity and inclusiveness
- Button text changed from "Go to Registration" to "Go to Dashboard"
- **Files Modified**:
- `src/static/js/buy-now.js` - Enhanced fallback authentication flow messaging
- `src/static/js/modal-system.js` - Enhanced modal system authentication flow
### 3. Order Management Integration ✅ COMPLETE
**Issue**: Items added to cart or purchased via buy-now are not appearing in orders
- **Root Cause**: Frontend JavaScript accessing wrong API response structure due to ResponseBuilder wrapping
- **Architectural Decision**: **User-Centric Data Storage Pattern**
- Orders are stored as part of user's persistent data (`UserPersistence`) rather than separate `OrderStorage`
- This creates a **localized source of truth** where each user owns their complete data set
- Follows industry standards for user-centric data management and GDPR compliance
- Enables easier data portability and user account management
- **Solution Implemented**:
- ✅ **Backend**: Orders correctly saved via `UserPersistence::save_user_data()` in instant purchase flow
- ✅ **API Layer**: ResponseBuilder automatically wraps responses in `{"data": {...}, "success": true}` structure
- ✅ **Frontend Fix**: Updated JavaScript to access `data.data.orders` instead of `data.orders`
- ✅ **UX Enhancement**: Added order sorting by creation date (latest first)
- **Technical Implementation**:
- `instant_purchase.rs`: Orders pushed to `persistent_data.orders` vector
- `order.rs`: `get_user_orders()` reads from UserPersistence, sorts by `created_at` DESC
- `orders.html`: Frontend handles nested ResponseBuilder JSON structure
- **Data Flow**: Purchase → UserPersistence → API → ResponseBuilder → Frontend
- **Files Modified**:
- `src/views/dashboard/orders.html` - Fixed JavaScript data access pattern
- `src/services/order.rs` - Added descending order sorting by creation date
---
## Implemented Service-Provider → Marketplace → Consumer Flow — COMPLETED 2025-08-12
- __Creation (Provider)__
- Service/App creation via dashboard APIs:
- Services: `POST /api/dashboard/services`, `PUT /api/dashboard/services/{id}`, `DELETE /api/dashboard/services/{id}`
- Apps: `POST /api/dashboard/apps`, `PUT /api/dashboard/apps/{id}`, `DELETE /api/dashboard/apps/{id}`
- Generic products: `GET/POST /api/dashboard/products`
- Data persists in `user_data/{email}.json` under `products`.
- __Aggregation (Marketplace)__
- `projectmycelium/src/services/product.rs::ProductService::get_all_products()` aggregates fixtures + user products (+ optional slice products) and applies category normalization via `canonical_category_id`.
- Dev cache: optional TTL cache controlled by `APP_CATALOG_CACHE` and `APP_CATALOG_CACHE_TTL_SECS`.
- __Visibility (Marketplace → Consumer)__
- `src/controllers/marketplace.rs::services()` filters products where `category_id` is `service` or `application`, converts prices to the user's currency, and injects `service_products` into the template.
- `src/views/marketplace/services.html` renders `service_products` expecting objects of the form `{ product, price, formatted_price }`.
- __Purchase Flows__
- Add to cart: `POST /api/cart/add` → `OrderController::add_to_cart`.
- Buy now: `src/static/js/buy-now.js` calls
- Affordability: `GET /api/wallet/check-affordability?amount=<Decimal>` → returns `{ can_afford: bool, shortfall_info?: {...} }` in ResponseBuilder envelope.
- Instant purchase: `POST /api/wallet/instant-purchase` with `InstantPurchaseRequest` → creates order and persists via `UserPersistence`.
- Related wallet endpoints: `GET /api/wallet/balance`, `GET /api/wallet/transactions`, `POST /api/wallet/quick-topup`.
- __Frontend Integration__
- Response pattern: APIs return a ResponseBuilder envelope `{ success, data }`; frontend unwraps with `const data = result.data || result;`.
- CSP-compliant hydration: pages pass JSON via `<script type="application/json" id="...">` blocks; all JS external (e.g., `src/static/js/services.js`, `buy-now.js`, `dashboard_cart.js`).
- __Generalization__
- App providers follow the same flow. Canonical category `application` is normalized and displayed on `/marketplace/applications` with equivalent filtering, pricing, and purchase behavior.
## Dashboard TODOs (Consolidated — 2025-08-15)
- Deprecation: `docs/dev/design/current/marketplace-todo-dashboard.md` is deprecated; update this file instead.
- Open items:
- `/dashboard/user` — My Services (Purchased): implement GET `/api/dashboard/user/services/purchased?product_type=service|app|bundle|any`, render in `src/views/dashboard/user.html`. Acceptance: items/empty state; currency formatting; no console errors.
- `/dashboard/service-provider` — Service Requests: implement GET `/api/dashboard/service-provider/requests?product_type=service|app|bundle|any`, render in `src/views/dashboard/service_provider.html`. Acceptance: list/empty state; no console errors.
- `/dashboard/farmer`: guard 404s from `/api/dashboard/slice-statistics` and handle non-JSON; fix `averageDiscount` ReferenceError; guard undefined `.length`; avoid duplicate listeners with init guard.
- `/dashboard/app-provider`: avoid duplicate `dashboard-app-provider.js` inclusion to prevent "Identifier 'AppProviderDashboard' has already been declared".
- Cross-product Types Extension: support `product_type` param across dashboards; reuse `ProductService::get_all_products()` normalization.
- Manual testing (brief):
- Start server and open relevant dashboards.
- Verify creation, persistence, and marketplace visibility for a new app/service.
- Check ResponseBuilder unwrap usage: `const data = result.data || result;`.
- Confirm invoice CTAs honor `invoice_available` and use `invoice_url`.
- Watch console/network for 404s and JSON parse errors; fix guards.
## 🚨 New User-Reported TODOs (2025-08-07)
- [x] Service Provider: Creating a new service causes modal flicker — FIXED 2025-08-12 (root-cause; fade preserved). Background hover transitions on cards/rows/items caused repaints during modal fade. Tightened transitions; suppressed hover transitions under `body.modal-open`; restored `.modal.fade`; added GPU hints to modal buttons. Files: `src/static/css/styles.css`, `src/views/dashboard/service_provider.html`.
- [ ] SLA: New SLA is saved under `user_data/` but does not appear in the list. Ensure frontend fetches from persistent API (`/api/dashboard/slas`) and unwraps ResponseBuilder via `const data = result.data || result;`. Refresh list after create/save/delete. Confirm mocks disabled for SLA in config. Files: `src/static/js/dashboard-service-provider.js`, `src/controllers/dashboard.rs`.
- [ ] Persistent data only: audit and remove any remaining mock/fixture/stub data from runtime paths. Search `src/` for "mock", "fixture", "stub". Verify all reads/writes go through `user_data/` and `UserPersistence`.
- [x] Service Provider Dashboard: remove all `user.mock_data` references and align JS/template with persistent `service_provider_data` using `*_usd` fields. ✅ COMPLETED 2025-08-15
- [x] App Provider Dashboard: remove any `user.mock_data` references; inject and bind persistent `app_provider_data` with `*_usd` fields; update `dashboard-app-provider.js` accordingly. ✅ COMPLETED 2025-08-15
- [ ] User Dashboard: ensure template/JS use only persistent `user_dashboard_data`; remove mock fallbacks and align currency fields.
- [x] Navbar cart counter not updating after delete: ensure delete-from-cart updates count. Implemented event-driven update and fresh fetch with `cache: 'no-store'`. ✅ FIXED 2025-08-08
- [ ] Proceed-to-cart shows "Insufficient USD credits. Need $0.00 more." even with sufficient wallet: audit wallet check in cart flow for ResponseBuilder wrapping and TFC vs USD logic; fix Decimal math and messaging.
- [ ] Add to cart should not check wallet funds: remove funds check on add-to-cart; enforce funds check only at checkout. Align with buy-now logic which already deducts correctly and creates orders.
- [x] Orders: "Download invoice" not working: Implemented marketplace order invoice HTML view and UI wiring. ✅ FIXED 2025-08-09
- [x] Orders page: remove "Reorder" option from `src/views/dashboard/orders.html`. ✅ FIXED 2025-08-08
- [x] Orders page: "Contact support" link uses ThreeFold support URL consistently. ✅ FIXED 2025-08-08
Note: Add tests for the above, and ensure all frontend API parsing uses `const data = result.data || result;`.
## 🧩 New Findings & TODOs (2025-08-09)
### 🔥 Critical: Marketplace Order Invoices ✅ COMPLETED 2025-08-09
- Backend: Implemented GET `/orders/{id}/invoice` → HTML view (Tera) for print in browser.
- Deliberately not implemented now: direct download API (`/api/orders/{id}/invoice`).
- Rationale: "View Invoice" + browser Print → Save as PDF is sufficient for current UX; avoids extra complexity and PDF/file generation. No immediate need for programmatic downloads. Can be added later if integrations require it.
- Controller: Implemented `OrderController::get_order_invoice` in `src/controllers/order.rs` with:
- Ownership check using `session["user_email"]` when available.
- Dual-source lookup: try in-memory `OrderStorage`; if not found, fallback to `UserPersistence` (email-based). Fixes buy-now invoices not found.
- Template: Created `src/views/marketplace/order_invoice.html` (order id, date, items, qty, unit price, line totals, subtotal/total, payment method, billing email, print button).
- Frontend: Wired `src/views/dashboard/orders.html` to open `/orders/{id}/invoice` in a new tab.
- CTA text updated to "View Invoice" with eye icon.
- JS handlers renamed: `downloadInvoice` → `viewInvoice`, `downloadInvoiceFromModal` → `viewInvoiceFromModal`.
- API enrichment (optional): add `invoice_available` and `invoice_url` in `/api/orders` and `/api/orders/{id}`.
- Acceptance: Invoice view renders for owned orders; 404 if not found; 403 if access denied. Achieved for HTML view.
### ✅ Marketplace Overview De-duplication (Featured vs Popular) — COMPLETED 2025-08-10
- Behavior: "Popular Applications" excludes any products already shown in "Featured Items" on `/marketplace`.
- Implementation: `src/controllers/marketplace.rs` builds a set of featured product IDs and filters the popular applications list before price conversion/render.
- Rationale: Avoid duplicate cards on the overview while keeping "Featured" as a curated, source-agnostic section.
- Acceptance: WireGuard VPN (featured) no longer appears again under Popular; verified in fixtures and mock modes.
### ✅ Marketplace Dashboard 500 Fix (Tera parsing + test setup) — COMPLETED 2025-08-10
- Issue: Dashboard returned HTTP 500 when mocks were disabled due to a Tera parsing error and missing Tera initialization in tests.
- Root Causes:
- Tera condition syntax: parenthesized filter expressions like `(collection | length) > 0` cause a parse error. Correct form is `collection | length > 0` without parentheses.
- Tests not registering custom Tera functions, so templates failed in the test environment.
- Fixes:
- Template: Updated `src/views/marketplace/dashboard.html` to remove parentheses around `| length` checks and guard nested field access.
- Tests: Initialized Tera and registered custom functions in `tests/mock_gating.rs` before configuring routes.
- Tests Added:
- `test_marketplace_dashboard_loads_with_mocks_disabled` → expects HTTP 200
- `test_rent_product_returns_404_when_mocks_disabled` → expects HTTP 404
- Test Setup Pattern (Actix + Tera):
```rust
use actix_web::{App, test, web};
use tera::Tera;
use threefold_marketplace::utils; // register_tera_functions
#[actix_web::test]
async fn test_marketplace_dashboard_loads_with_mocks_disabled() {
let mut tera = Tera::new("src/views/**/*.html").expect("init tera");
utils::register_tera_functions(&mut tera);
let app = test::init_service(
App::new()
.app_data(web::Data::new(tera))
.configure(threefold_marketplace::routes::configure_routes),
).await;
let req = test::TestRequest::get().uri("/marketplace").to_request();
let resp = test::call_service(&app, req).await;
assert!(resp.status().is_success());
}
```
Notes:
- Mirror production Tera setup in tests (template glob + custom functions).
- Avoid parentheses around filter expressions in Tera conditions.
### ✅ Category ID Normalization (Fixtures) — COMPLETED 2025-08-10
- Implementation: `src/services/product.rs::ProductService` normalizes plural/alias category IDs to canonical singulars during fixtures load.
- Examples: "applications" → "application", "gateways" → "gateway".
- Data: `user_data/products.json` uses singular `category_id` values.
- Outcome: Category pages and filters align; products appear under the correct categories.
### ✅ Category Normalization (User Products) — COMPLETED 2025-08-12
- Implemented mapping of professional service subcategories (Consulting, Deployment, Support, Training, Development, Maintenance) to canonical `service` in `projectmycelium/src/services/product.rs::canonical_category_id`.
- Ensures user-created services stored under `user_data/{email}.json` with legacy subcategory IDs are visible on the marketplace.
- `src/controllers/marketplace.rs::services()` includes both `service` and `application` for backward compatibility while normalization propagates.
### ✅ Catalog Dev Cache (Development) — COMPLETED 2025-08-10
- Purpose: Speed up local dev by caching the aggregated catalog (fixtures + user-owned + optional slices).
- Implementation: In-memory TTL cache in `ProductService` keyed by slice toggle (`include_slice_products`).
- Static: `OnceLock<Mutex<CatalogCache>>` with buckets for with/without slices.
- `get_all_products()` uses TTL; miss/expiry recomputes via `aggregate_all_products_uncached()` and updates cache.
- Dedupe semantics and category normalization remain intact.
- Config:
- Flags: `APP_CATALOG_CACHE` (true/false), `APP_CATALOG_CACHE_TTL_SECS` (u64).
- Defaults: Dev/Test enabled, TTL=5s. Prod disabled unless explicitly enabled.
- Accessors: `AppConfiguration::is_catalog_cache_enabled()`, `catalog_cache_ttl_secs()`.
- Acceptance:
- Catalog updates reflect after TTL; no duplicates; category pages correct.
- Build passes (`cargo check`).
- Phase Roadmap:
- Phase 0 (now): Simple in-memory TTL cache.
- Phase 1: Optional dev-only cache-bust.
- Phase 2: Optional finer-grained or Redis-backed cache toggle for prod.
### ℹ️ Runtime Modes & Commands
- Fixtures mode (recommended): `make fixtures-run` or `APP_DATA_SOURCE=fixtures APP_FIXTURES_PATH=./user_data APP_ENABLE_MOCKS=0 cargo run --bin projectmycelium`
- Mock mode (dev-only): `APP_DATA_SOURCE=mock APP_ENABLE_MOCKS=1 cargo run --bin projectmycelium` to visualize legacy mock data.
- Notes: Production builds must not enable mocks; fixtures are seed/demo-only and not write targets.
### ✅ DevX: Rust Error-Only Compilation Logs — COMPLETED 2025-08-12
To speed up debugging and keep logs readable, we added an error-only workflow for `cargo check`.
- **Script**: `scripts/dev/cargo-errors.sh`
- **Make targets**:
- `make check-errors`
- `make fixtures-errors` (runs with fixtures env)
- **Output**: `/tmp/cargo_errors_only.log` (override with `OUT=/path/to/file.log`)
- **Behavior**: warnings are fully suppressed; only errors are logged. Exit code mirrors `cargo check`.
Usage:
```bash
make check-errors
OUT=/tmp/my_errors.log make check-errors
make fixtures-errors
```
Quick helpers:
```bash
grep -c '^error' /tmp/cargo_errors_only.log
sed -n '1,80p' /tmp/cargo_errors_only.log
```
### 🔥 Critical: Insufficient Balance – Unified Error Contract
- [ ] Decide and document single status code for insufficient funds responses.
- Recommendation: 402 Payment Required.
- [ ] Define canonical error JSON shape (via ResponseBuilder), e.g.:
```json
{
"success": false,
"error": {
"code": "INSUFFICIENT_FUNDS",
"message": "Insufficient balance",
"details": {
"currency": "USD",
"wallet_balance_usd": 0,
"required_usd": 0,
"deficit_usd": 0
}
}
}
```
- [ ] Audit and update flows to emit the canonical contract:
- `src/controllers/order.rs`, `src/services/order.rs`, `src/services/instant_purchase.rs`
- Wallet-dependent controllers: `wallet.rs`, `pool.rs`, `rental.rs`
- [ ] Frontend: consume `error.details` and show a single consistent message:
- "Insufficient balance. Need $<deficit> more." (currency-aware)
- Avoid hardcoding numbers; read from `details`.
- Keep `const data = result.data || result;` for wrapper safety.
- [ ] Tests:
- API tests verify status code and JSON shape for each flow (checkout, buy-now, cart quantity validations if applicable).
- Frontend tests/steps verify rendering and CTA behavior (e.g., "Add Funds").
- [ ] Compatibility/migration notes:
- Document any legacy shapes temporarily supported and plan a removal date.
Acceptance Criteria:
- Single status code across insufficient funds responses.
- Identical JSON structure across all emitting endpoints.
- Frontend shows a unified message and uses numeric values from `error.details` everywhere.
- Tests cover at least one success and one insufficient-funds path per major flow.
### ⚡ High: Buyer My Services & Provider Service Requests — NEW 2025-08-13
- Goal: complete the post-purchase dashboard flows for services, then extend to all product types (param-driven `product_type`).
- Backend endpoints (ResponseBuilder):
- GET `/api/dashboard/user/services/purchased?product_type=service|app|bundle|any` — items bought by current user.
- GET `/api/dashboard/service-provider/requests?product_type=service|app|bundle|any` — orders where current user is seller/provider.
- Frontend bindings:
- `/dashboard/user` → render “My Services (purchased)” in `src/views/dashboard/user.html` using `src/static/js/dashboard-user.js`.
- `/dashboard/service-provider` → render “Service Requests” in `src/views/dashboard/service_provider.html` using `src/static/js/dashboard-service-provider.js`.
- Unwrap API responses with `const data = result.data || result;`. Reads `{ cache: 'no-store' }`, mutations `{ credentials: 'same-origin' }`.
- Error contract: any related mutations must use the unified insufficient balance envelope.
- Acceptance:
- Buyer sees purchased services list; Provider sees incoming requests; empty states handled; currency-formatted display consistent.
- Same flow works for apps/bundles via `product_type`.
### ⚡ High: Cart Events, Cache, Credentials – Standardization ✅ COMPLETED 2025-08-09
- Implemented across views:
- `src/views/dashboard/cart.html`
- `src/views/marketplace/cart.html`
- `src/views/marketplace/cart_full.html`
- `src/views/marketplace/cart_standalone.html`
- `src/views/cart.html` (guest)
- Event emission unified: all flows call `window.emitCartUpdated(cartCount?)` instead of dispatching `CustomEvent` directly.
- Reads standardized: all `fetch('/api/cart')` include `{ cache: 'no-store', credentials: 'same-origin' }` to prevent stale data and ensure session cookies.
- Mutations standardized: all POST/PUT/DELETE to `/api/cart` and `/api/cart/item/{id}` include `{ credentials: 'same-origin' }`.
- Robustness: tolerant JSON parsing for 204/no-body responses where applicable.
- Verification: Manual tests across guest and logged-in flows confirm consistent navbar badge updates and UI state.
### 📋 Medium: Mock/Fixture Gating for Production
- Introduce `AppConfig.enable_mock_data` (default false in production) to guard any legacy dev-only readers/writers (e.g., `MockDataService`, certain `session_manager.rs` paths).
- Enforce persistent-only sources (`user_data/` via `UserPersistence`) in production.
- Acceptance: production runtime has zero mock reads/writes; dev-only paths documented.
### 📋 Medium: Orders API Contract Improvements — COMPLETED 2025-08-13
- Added `invoice_available` and `invoice_url` fields to order payloads to drive UI state.
- Acceptance: orders UI enables/disables invoice actions based on payload.
### 💡 Tests
- Integration tests: invoice endpoints (auth/ownership, headers), insufficient balance contract, cart event → badge update.
- Unit tests: currency shortfall formatting.
- Acceptance: tests pass in CI.
### 📦 Fixtures Mode: Seeded Products + Manual Checklist ✅ COMPLETED 2025-08-09
- Seeded `user_data/products.json` with three products (WireGuard VPN, Public Gateway Bundle, Object Storage 100GB).
- Added manual checklist: `docs/dev/design/current/ux/manual_fixture_test_checklist.md`.
- Personas doc updated with seeded products: `docs/dev/design/current/ux/current_personas.md`.
- Make targets: `make fixtures-run`, `make fixtures-check`.
### 🧭 Decision: User-Owned Products & Derived Catalog (No Dual Writes) — 2025-08-09
- Single Source of Truth (SOT): product is owned by creator (user). Writes go to user persistence (now) / `products` table (DB).
- Global catalog is a derived read model built from all user-owned products (and seeds in fixtures). Do NOT write to both.
- In fixtures mode, `user_data/products.json` is seed/demo-only; not a write target.
- Next tasks:
- ✅ 2025-08-10: Added id-based dedupe in `ProductService::get_all_products()`; later sources override earlier ones. `get_product_by_id()` now searches the aggregated, deduped list.
- Optional dev cache: generate `user_data/catalog.products.json` from aggregator (marked generated).
- Plan DB/PostgREST (see Architecture Guide update): tables, `public_products` view, RLS.

### Recent Accomplishments (2025-08-08)
- ✅ **Dashboard Controller Migration Complete**: Successfully migrated all 331/331 HttpResponse patterns to ResponseBuilder
- ✅ **17 Pattern Types Migrated**: Redirect (3), JSON Success (6), JSON Error (5), Unauthorized (1), Internal Error (1), Plain Text (1)
- ✅ **Full Functional Testing**: Dashboard application runs successfully with all features working
- ✅ **100% Builder Pattern Coverage**: All controllers now use ResponseBuilder architecture
- ✅ **Zero Compilation Errors**: Maintained clean build throughout entire migration process
- ✅ **Architecture Milestone**: Complete ResponseBuilder pattern implementation across entire codebase
- ✅ **Cart Count Consistency & Persistence Cleanup**: Fixed stale navbar cart count after restart/build.
- Backend: `src/services/order.rs::get_cart_with_details()` now:
- Cleans orphaned cart items whose `product_id` no longer exists
- Recomputes `item_count` from valid items only
- Persists cleaned cart to session and `user_data/*_cart.json`
- Frontend:
- Global `updateCartCount()` in `src/views/base.html` fetches `/api/cart` with `cache: 'no-store'`
- `src/views/marketplace/cart.html` dispatches `cartUpdated` on remove/clear and calls `window.updateCartCount()`
- `src/views/marketplace/dashboard.html` avoids overriding global by renaming to `updateCartCountLocal()` and using `window.updateCartCount()`
- Result: Navbar badge always reflects true backend state, including after app restarts.
- ✅ Checkout & Orders Flow Alignment (2025-08-08)
- Checkout redirect fix: In `src/views/marketplace/checkout.html` `processPayment()` now unwraps the ResponseBuilder envelope, extracts `order_id` and `confirmation_number` from `data`, and builds a valid confirmation URL.
- Post-purchase cart clear: DELETE `/api/cart` includes `{ credentials: 'same-origin' }` to ensure session consistency after order placement.
- Order status alignment: Successful wallet/cart checkout is now marked `Completed` both in-memory and when persisted to user data.
- Backend: `src/services/order.rs::process_payment()` updates to `OrderStatus::Completed` and attaches payment details.
- Persistence: Wallet flow persists the order as `Completed` with payment details in `UserPersistence`.
- Buy Now already sets `Completed`; both flows are now consistent.
- Dashboard display hardening: `src/views/dashboard/orders.html` maps `confirmed`/`completed` to green and lowercases status before color mapping for robustness.
- ✅ Cart Clear UX: Post-Reload Success Toast (2025-08-08)
- Behavior: After successful clear, we reload the page for state consistency and show a success toast after reload.
- Mechanism: Set `sessionStorage.setItem('cartCleared','1')` before `window.location.reload()`. On `DOMContentLoaded`, check the flag, show toast, then remove it.

## Appendix: Marketplace Currency Refactor – Work Done
### Summary
- Refactored dashboard Orders UI and server to use the user's preferred currency dynamically, aligning with Wallet and Cart.
- Eliminated hardcoded symbols by injecting `currency_symbol` and `display_currency` into templates and formatting amounts server-side where possible.
### Code Changes
- orders template: `src/views/dashboard/orders.html`
- Added `formatCurrencyAmount()` helper to place symbol correctly (prefix for $, €, C$, etc.; suffix for alphabetic symbols like TFC/TFT).
- Updated aggregated "Total Spent" to use the helper instead of a hardcoded prefix.
- Continued using server-injected `currency_symbol`/`display_currency`.
- dashboard controller: `src/controllers/dashboard.rs`
- Injected `currency_symbol` and `display_currency` into Tera context for:
- `cart_section()`
- `orders_section()`
- orders controller: `src/controllers/order.rs`
- Fixed compile error (E0425) in `view_order_history_legacy()` by defining `display_currency` before using it for conversions/formatting.
- Updated `get_orders_json()` to convert/format item and order totals in the preferred `display_currency` using `CurrencyService::convert_amount` + `format_price`, and to return the preferred currency code in `currency`.
### Rationale
- Centralize currency conversion/formatting in backend (`CurrencyService`) to reduce JS complexity and ensure consistency across Orders, Cart, Wallet, and Navbar.
- Ensure all user-facing totals and labels reflect the preferred currency and appropriate symbol placement.
### Build/Status
- Addressed `E0425: cannot find value display_currency` in Orders legacy view.
- There are many warnings (mostly unused variables); non-blocking for functionality and can be cleaned later.
### Frontend Externalization & JSON Hydration
- Externalized dashboard scripts from `src/views/dashboard/index.html` into `static/js/dashboard.js`.
- Added a JSON data block in `index.html` using `<script type="application/json" id="dashboard-chart-data">` to safely hydrate chart data (no inline template directives inside JS).
- Dashboard JS reads hydrated data, initializes all charts, and updates wallet balance/currency via `/api/navbar/dropdown-data` using the ResponseBuilder-safe unwrap pattern.
- Benefits: CSP-friendly, caching for JS, reduced template lints, clearer separation of concerns.
### Next Steps
- Adjust `src/views/dashboard/orders.html` JS to rely solely on server-provided formatted fields for item/unit/subtotal/total where available.
- Verify that Dashboard main page and Navbar still display wallet balance and labels in the preferred currency.
- Run `cargo build` and targeted tests to confirm no regressions.

# Project Mycelium - Current Architecture Guide
## Complete Transition Roadmap to Pure USD Credits System
### 🎯 **Project Vision (Updated 2025)**
The Project Mycelium is a **production-ready, fully functional e-commerce platform** built in Rust that demonstrates a complete decentralized marketplace ecosystem with modern SaaS user experience.
**Current Status**: In transition from legacy TFP system to pure USD Credits architecture. This document serves as the blueprint for completing the full transition to industry-standard USD Credits.
**Target**: Pure USD Credits system with automatic balance management, comprehensive authentication flows, and seamless integration capabilities.
---
## 🚨 **Critical Architecture Decision: Complete TFP → USD Transition**
### **Current Problem: Hybrid System (Suboptimal)**
The marketplace currently uses a **confusing hybrid approach**:
- **Backend**: Stores values in TFP (legacy)
- **Frontend**: Displays USD Credits (modern)
- **Conversion**: Complex 10:1 TFP→USD conversion layer
### **Recommended Solution: Pure USD Credits**
**Industry Standard Approach** (like OpenAI, Stripe, AWS):
- **Backend**: Store direct USD values
- **Frontend**: Display direct USD values
- **No Conversion**: What you see is what's stored
---
## 💰 **Currency Architecture: Current vs Target**
### **Current State: Hybrid Architecture (Needs Refactoring)**
```mermaid
graph TD
A[User Sees: $10.00] --> B[Display Layer]
B --> C[Conversion: 1 USD = 10 TFP]
C --> D[Backend Storage: 100 TFP]
D --> E[JSON Database: TFP Values]
E --> F[TFP Calculations]
F --> G[Convert Back to USD]
G --> A
style D fill:#ffcccc
style E fill:#ffcccc
style F fill:#ffcccc
style C fill:#ffcccc
```
**Problems with Current Approach:**
- ❌ Complex conversion logic everywhere
- ❌ Confusing for developers (see $10, stored as 100 TFP)
- ❌ Potential rounding errors
- ❌ Performance overhead
- ❌ 153 TFP references still in UI
### **Target Architecture: Pure USD Credits (Recommended)**
```mermaid
graph TD
A[User Sees: $10.00] --> B[Direct USD Storage: $10.00]
B --> C[USD Calculations]
C --> D[JSON Database: USD Values]
D --> E[Direct USD Display]
E --> A
style B fill:#ccffcc
style C fill:#ccffcc
style D fill:#ccffcc
style E fill:#ccffcc
```
**Benefits of Pure USD:**
- ✅ **Industry Standard**: Matches SaaS leaders
- ✅ **Simple Architecture**: No conversion layer
- ✅ **Better UX**: Users think in dollars, system stores dollars
- ✅ **Easier Development**: Predictable data flow
- ✅ **Better Performance**: Direct calculations
- ✅ **Easier Testing**: Direct USD values in tests
---
## 🔐 **Authentication & Security Architecture (Enhanced)**
### **Current Authentication Flow**
Based on [`authentication-flow.md`](authentication-flow.md), the system implements:
#### **Route Protection Strategy**
```rust
// Dashboard Protection: Welcome Page Pattern
pub async fn dashboard_index(tmpl: web::Data<Tera>, session: Session) -> Result<impl Responder> {
match session.get::<String>("user") {
Ok(Some(user_email)) => {
// Show authenticated dashboard
render_authenticated_dashboard(&tmpl, &user_email)
}
_ => {
// Show welcome page with login/register options
render_welcome_page(&tmpl)
}
}
}
```
#### **API Authentication**
```rust
// Authentication status endpoint
GET /api/auth/status
// Frontend integration
async function checkAuthentication() {
const response = await fetch('/api/auth/status');
const result = await response.json();
return result.authenticated === true;
}
```
#### **Cart System: Guest-Friendly UX**
- ✅ **Add to Cart**: Works without authentication
- ✅ **Checkout**: Requires authentication
- ✅ **Buy Now**: Requires authentication with clear messaging
---
## 📊 **Data Architecture: Current vs Target Models**
### **Current Data Model (Hybrid - Needs Migration)**
```rust
// CURRENT (Confusing)
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct UserPersistentData {
pub user_email: String,
pub wallet_balance: Decimal, // Stored as TFP (confusing!)
pub transactions: Vec<Transaction>, // Mixed TFP/Credits types
pub display_currency: Option<String>, // "USD" but stored as TFP
// Services with TFP pricing
pub services: Vec<Service>, // price_per_hour in TFP
pub apps: Vec<PublishedApp>, // revenue in TFP
pub nodes: Vec<FarmNode>, // earnings in TFP
}
// Current transaction types (mixed)
pub enum TransactionType {
CreditsPurchase { payment_method: String }, // NEW
TFPPurchase { payment_method: String }, // LEGACY
// ... mixed types
}
```
### **Target Data Model (Pure USD - Recommended)**
```rust
// TARGET (Clean & Clear)
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct UserPersistentData {
pub user_email: String,
pub wallet_balance_usd: Decimal, // Direct USD storage
pub transactions: Vec<Transaction>, // Pure USD transactions
// Auto Top-Up (USD-based)
pub auto_topup_settings: Option<AutoTopUpSettings>,
// Services with USD pricing
pub services: Vec<Service>, // price_per_hour_usd
pub apps: Vec<PublishedApp>, // revenue_usd
pub nodes: Vec<FarmNode>, // earnings_usd
// Profile data
pub name: Option<String>,
pub country: Option<String>,
pub timezone: Option<String>,
}
// Clean transaction types (USD only)
pub enum TransactionType {
CreditsPurchase { payment_method: String, amount_usd: Decimal },
CreditsTransfer { to_user: String, amount_usd: Decimal },
AutoTopUp { amount_usd: Decimal, payment_method: String },
Purchase { product_id: String, amount_usd: Decimal },
Earning { source: String, amount_usd: Decimal },
}
```
### **Data Migration Example**
```json
// BEFORE (Current - Confusing)
{
"user_email": "provider@example.com",
"wallet_balance": 2450.75, // TFP (user sees $245.08)
"services": [
{
"price_per_hour": 750, // TFP (user sees $75.00)
"name": "WordPress Dev"
}
]
}
// AFTER (Target - Clear)
{
"user_email": "provider@example.com",
"wallet_balance_usd": 245.08, // Direct USD
"services": [
{
"price_per_hour_usd": 75.00, // Direct USD
"name": "WordPress Dev"
}
]
}
```
---
## 🔧 **API Architecture: Current vs Target**
### **Current API (Mixed TFP/Credits)**
```rust
// Current endpoints (some legacy, some new)
POST /api/wallet/buy-credits // NEW - Credits
POST /api/wallet/buy-tfp // LEGACY - TFP (remove)
POST /api/wallet/transfer // LEGACY - TFP (remove)
POST /api/wallet/transfer-credits // NEW - Credits
// Mixed response formats
pub struct WalletResponse {
pub success: bool,
pub message: String,
pub new_balance: Option<Decimal>, // TFP or USD?
}
```
### **Target API (Pure USD Credits)**
```rust
// Clean, consistent endpoints
POST /api/wallet/buy-credits
POST /api/wallet/sell-credits
POST /api/wallet/transfer-credits
GET /api/wallet/balance
POST /api/wallet/auto-topup/configure
POST /api/wallet/auto-topup/trigger
// Consistent USD response format
pub struct CreditsResponse {
pub success: bool,
pub message: String,
pub transaction_id: Option<String>,
pub balance_usd: Decimal, // Always USD
pub amount_usd: Decimal, // Always USD
}
```
---
## 🎭 **User Personas: Updated for Pure USD**
### **Service Provider Workflow (Target)**
```rust
pub async fn add_service(form: ServiceForm, session: Session) -> Result<impl Responder> {
// User enters $75.00/hour
let service = Service::builder()
.name(form.name)
.price_per_hour_usd(form.price_usd) // Direct USD storage
.build()?;
// Store directly in USD (no conversion)
UserPersistence::add_user_service(&user_email, service)?;
// Display directly in USD (no conversion)
let marketplace_product = create_marketplace_product_from_service(&service);
MockDataService::add_product(marketplace_product);
}
```
### **Auto Top-Up Integration (Target)**
```rust
pub async fn process_purchase(
user_email: &str,
amount_usd: Decimal,
) -> Result<PurchaseResult, String> {
// Check USD balance directly
let current_balance = get_user_balance_usd(user_email)?;
// Auto top-up if needed (USD amounts)
if current_balance < amount_usd {
if let Some(settings) = get_auto_topup_settings(user_email)? {
if settings.enabled && current_balance <= settings.threshold_usd {
trigger_auto_topup_usd(user_email, settings.topup_amount_usd).await?;
}
}
}
// Process USD transaction directly
deduct_balance_usd(user_email, amount_usd)?;
Ok(PurchaseResult::Success)
}
```
---
## 📋 **Complete Transition Roadmap**
### **Phase 1: Backend Data Migration (Critical)**
#### **1.1 Database Schema Migration**
```rust
// Migration script needed
pub fn migrate_tfp_to_usd() -> Result<(), String> {
for user_file in glob("./user_data/*.json")? {
let mut user_data: UserPersistentData = load_user_data(&user_file)?;
// Convert TFP balances to USD
user_data.wallet_balance_usd = user_data.wallet_balance / dec!(10.0);
// Convert service pricing
for service in &mut user_data.services {
service.price_per_hour_usd = service.price_per_hour / dec!(10.0);
}
// Convert transaction amounts
for transaction in &mut user_data.transactions {
transaction.amount_usd = transaction.amount / dec!(10.0);
}
save_user_data(&user_file, &user_data)?;

## 🎯 **Implementation Patterns for Pure USD**
### **Controller Pattern (Updated)**
```rust
impl WalletController {
pub async fn buy_credits(
request: web::Json<BuyCreditsRequest>,
session: Session
) -> Result<impl Responder> {
let user_email = get_user_from_session(&session)?;
// Direct USD processing (no conversion)
let amount_usd = request.amount_usd;
// Process payment in USD
let payment_result = process_payment_usd(&request.payment_method, amount_usd).await?;
// Add USD directly to balance
add_balance_usd(&user_email, amount_usd)?;
// Record USD transaction
record_transaction(&user_email, TransactionType::CreditsPurchase {
payment_method: request.payment_method.clone(),
amount_usd,
})?;
Ok(HttpResponse::Ok().json(CreditsResponse {
success: true,
message: format!("Added ${:.2} to your account", amount_usd),
balance_usd: get_balance_usd(&user_email)?,
amount_usd,
}))
}
}
```
### **Service Pattern (Updated)**
```rust
impl FarmerService {
pub fn get_farmer_earnings_usd(&self, user_email: &str) -> Vec<EarningRecord> {
if let Some(user_data) = UserPersistence::load_user_data(user_email) {
// Direct USD access (no conversion)
user_data.farmer_earnings.into_iter().map(|earning| {
EarningRecord {
date: earning.date,
amount_usd: earning.amount_usd, // Direct USD
source: earning.source,
}
}).collect()
} else {
Vec::new()
}
}
}
```

- **Wallet Dashboard**: Shows USD amounts with `${{ wallet_balance | format_decimal(precision=2) }}`
- **Marketplace Pricing**: Clear USD values throughout all 5 marketplace pages
- **Navigation**: Consistent "Credits Wallet" terminology
- **Price Filters**: Updated from "Min/Max Price (TFP)" to "Min/Max Price ($)"
#### 2. Backend Infrastructure (80% Complete)
- **Transaction Types**: Complete credits transaction types implemented:
```rust
CreditsPurchase { payment_method: String },
CreditsSale { currency: String, fiat_amount: Decimal, payout_method: String },
CreditsTransfer { to_user: String, note: Option<String> },
AutoTopUp { triggered_by_purchase: Option<String>, threshold_amount: Decimal, amount_usd: Decimal, payment_method: String }
```
- **Controller Methods**: Credits methods implemented in `src/controllers/wallet.rs` with proper request structs
- **Data Models**: `AutoTopUpSettings` fully implemented with builder pattern in `src/services/user_persistence.rs`
#### 3. Auto Top-Up Infrastructure (75% Complete)
- **Service Layer**: `AutoTopUpService` implemented with proper builder pattern
- **JavaScript Integration**: `BuyNowManager` in `src/static/js/buy-now.js` handles insufficient balance scenarios
- **Settings Management**: Complete data structures for thresholds, limits, and payment methods
- **Transaction Processing**: Auto top-up transaction type and processing logic implemented
### ❌ Critical Missing Components (15%)
#### 1. API Routes Not Registered (HIGH PRIORITY - BLOCKING)
**Issue**: Credits controller methods exist but are NOT registered in `src/routes/mod.rs`
**Missing Routes**:
```rust
// REQUIRED: Add to src/routes/mod.rs after line 100 in /api scope:
.route("/wallet/buy-credits", web::post().to(WalletController::buy_credits))
.route("/wallet/sell-credits", web::post().to(WalletController::sell_credits))
.route("/wallet/transfer-credits", web::post().to(WalletController::transfer_credits))
.route("/wallet/check-affordability", web::get().to(WalletController::check_affordability))
.route("/wallet/instant-purchase", web::post().to(WalletController::instant_purchase))
.route("/wallet/auto-topup/status", web::get().to(WalletController::get_auto_topup_status))
.route("/wallet/auto-topup/trigger", web::post().to(WalletController::trigger_auto_topup))
.route("/wallet/auto-topup/configure", web::post().to(WalletController::configure_auto_topup))
```
#### 2. Missing Controller Methods (HIGH PRIORITY - BLOCKING)
**Issue**: JavaScript calls these endpoints but controller methods don't exist
**Required Methods in `src/controllers/wallet.rs`**:
```rust
pub async fn check_affordability(session: Session, query: web::Query<AffordabilityQuery>) -> Result<impl Responder>
pub async fn get_auto_topup_status(session: Session) -> Result<impl Responder>
pub async fn trigger_auto_topup(session: Session, form: web::Json<TriggerAutoTopUpRequest>) -> Result<impl Responder>
pub async fn configure_auto_topup(session: Session, form: web::Json<ConfigureAutoTopUpRequest>) -> Result<impl Responder>
```
**Required Request Structs**:
```rust
#[derive(Debug, Deserialize)]
pub struct AffordabilityQuery {
pub amount: Decimal,
}
#[derive(Debug, Deserialize)]
pub struct TriggerAutoTopUpRequest {
pub required_amount: Decimal,
}
#[derive(Debug, Deserialize)]
pub struct ConfigureAutoTopUpRequest {
pub enabled: bool,
pub threshold_amount: Decimal,
pub topup_amount: Decimal,
pub payment_method_id: String,
pub daily_limit: Option<Decimal>,
pub monthly_limit: Option<Decimal>,
}
```
#### 3. Legal Documents Still Reference TFP (MEDIUM PRIORITY - LEGALLY REQUIRED)
**Issue**: Found 93 TFP references in legal documents
**Critical Updates Required**:
- `src/views/legal/terms.html:89`: "Transactions are conducted using the ThreeFold Point (TFP) system" → "USD Credits system"
- `src/views/legal/terms-service-providers.html`: Update payment processing references
- `src/views/legal/terms-farmers.html`: Update revenue sharing language
- Service provider agreement modals: Update TFP references to Credits
#### 4. Auto Top-Up UI Configuration (MEDIUM PRIORITY - FEATURE INCOMPLETE)
**Issue**: Users cannot configure auto top-up settings
**Required Components**:
- Auto top-up settings section in `src/views/dashboard/wallet.html`
- Configuration modal for threshold and top-up amounts
- Payment method selection integration
- Current settings display
---

## Recent Updates - Auto Top-Up Issue Resolution
### Issues Identified and Resolved (August 2, 2025)
#### 1. JSON Deserialization Error - FIXED ✅
**Problem**: Users encountered "Unexpected token 'J', "Json deser"... is not valid JSON" error when configuring auto top-up settings.
**Root Cause**: Mismatch between frontend JSON payload (6 fields) and backend `AutoTopUpSettings` struct (8 fields including DateTime fields).
**Solution Implemented**:
- Created `ConfigureAutoTopUpRequest` DTO struct in [`wallet.rs`](projectmycelium/src/controllers/wallet.rs:58)
- Updated [`configure_auto_topup`](projectmycelium/src/controllers/wallet.rs:1000) endpoint to use DTO pattern
- Backend now automatically sets `created_at` and `updated_at` timestamps
- Maintains clean API design where frontend only sends business data
#### 2. UI Display Issue - FIXED ✅
**Problem**: Auto top-up settings displayed as "$undefined" in the status table.
**Root Cause**: Frontend JavaScript accessing `result.threshold_amount` instead of `result.settings.threshold_amount`.
**Solution Implemented**:
- Updated JavaScript in [`wallet.html`](projectmycelium/src/views/dashboard/wallet.html:667) to access nested settings data
- Added proper null checking with `result.enabled && result.settings`
- Fixed both display logic and form population logic
#### 3. Payment Method Display Enhancement - COMPLETED ✅
**Enhancement**: Improved UX by showing user-friendly payment method names.
**Implementation**:
- Added `formatPaymentMethod()` function with mapping for common payment methods
- "credit_card" → "Credit Card", "paypal" → "PayPal", etc.
- Updated display code to use formatted names
#### 4. Monthly Limit Display Addition - COMPLETED ✅
**Enhancement**: Added Monthly Limit display alongside Daily Limit for complete visibility.
**Implementation**:
- Updated auto top-up status layout to show 5 columns: Threshold, Top-Up Amount, Payment Method, Daily Limit, Monthly Limit
- Proper formatting with "$X.XX" or "No Limit" display
- Balanced column layout for optimal visual presentation
### Current Auto Top-Up Status
- ✅ **Configuration**: Saves successfully without JSON errors
- ✅ **Display**: Shows all values with proper formatting
- ✅ **UX**: User-friendly payment method names
- ✅ **Completeness**: Both Daily and Monthly limits visible
- ✅ **Form Handling**: Populates correctly with existing settings
- ✅ **Functionality**: Full auto top-up system operational

Following the successful Credits system implementation, we have completed a **comprehensive legacy code cleanup** that significantly improves the codebase quality and maintainability.
#### **Legacy TFP Infrastructure Completely Removed**
**Backend Cleanup:**
- ✅ **Removed 6 TFP API routes** from [`routes/mod.rs`](projectmycelium/src/routes/mod.rs):
- `/wallet/buy-tfp`
- `/wallet/sell-tfp`
- `/wallet/transfer`
- `/dashboard/settings/add-tfp`
- `/pools/stake` (TFP staking)
- `/docs/tfp` redirect
- ✅ **Removed 3 TFP request structs** from [`wallet.rs`](projectmycelium/src/controllers/wallet.rs):
- `BuyTFPRequest`
- `SellTFPRequest`
- `TransferTFPRequest`
- ✅ **Removed 3 massive TFP methods** (~400+ lines of legacy code):
- `buy_tfp()` method (137 lines)
- `sell_tfp()` method (129 lines)
- `transfer_tfp()` method (132 lines)
**Frontend Cleanup:**
- ✅ **Updated all frontend API calls** to use Credits endpoints:
- [`wallet.html`](projectmycelium/src/views/dashboard/wallet.html) - Credits purchase/transfer
- [`pools.html`](projectmycelium/src/views/dashboard/pools.html) - Credits buy/sell for pools
- [`index.html`](projectmycelium/src/views/wallet/index.html) - Wallet Credits operations
#### **Critical Bug Fix - Credits Purchase JSON Error**
**Problem Identified:**
- Users encountered "Unexpected end of JSON input" error when purchasing Credits
- **Root Cause**: Frontend was calling removed TFP endpoints instead of Credits endpoints
**Solution Implemented:**
- Updated all frontend calls from `/api/wallet/buy-tfp` → `/api/wallet/buy-credits`
- Updated all frontend calls from `/api/wallet/sell-tfp` → `/api/wallet/sell-credits`
- Updated all frontend calls from `/api/wallet/transfer` → `/api/wallet/transfer-credits`
**Result**: Credits purchase now works perfectly without JSON errors ✅
#### **Transaction Display Overhaul - Complete Credits UI**
**Problem Identified:**
- Transaction history showed "TFP" amounts instead of "$" Credits
- Transaction types displayed as "Unknown" instead of proper Credits terminology
- JavaScript transaction rendering used legacy TFP logic
**Solution Implemented:**
- ✅ **Updated HTML template logic** in [`wallet.html`](projectmycelium/src/views/dashboard/wallet.html):
- Fixed transaction type detection: `CreditsPurchase`, `CreditsSale`, `CreditsTransfer`
- Updated amount display: `TFP` → `$` with proper decimal formatting
- Added support for all Credits transaction types with proper badge colors
- ✅ **Updated JavaScript transaction rendering**:
- Fixed `isPositive` detection to include Credits transaction types
- Updated `typeLabel` mapping for Credits terminology
- Changed amount display from `${amount} TFP` → `$${amount.toFixed(2)}`
- Added proper badge styling for Credits transaction types
**Result**: Transaction history now shows professional Credits display ✅
#### **Warning Analysis & Cleanup Strategy**
**Warning Assessment:**
- **Before**: 133 total warnings (16 lib + 117 bin)
- **After**: 135 total warnings (16 lib + 119 bin)
- **Net Result**: Warnings remained stable while removing 500+ lines of legacy code
**Analysis**: Most remaining warnings are intentional architectural features:
- Builder pattern methods (comprehensive APIs for future use)

# Files to update in order of priority:
1. projectmycelium/src/views/dashboard/farmer.html
2. projectmycelium/src/views/dashboard/user.html
3. projectmycelium/src/views/dashboard/index.html
4. projectmycelium/src/views/dashboard/service_provider.html
5. projectmycelium/src/views/dashboard/app_provider.html
```
**Pattern to Follow** (based on our wallet.html success):
```html
<!-- Before -->
<small class="text-muted">TFP/month</small>
<span>{{ amount }} TFP</span>
<!-- After -->
<small class="text-muted">$/month</small>
<span>${{ amount | format_decimal(precision=2) }}</span>
```
#### Phase 2: TFP Pools Redesign (Medium Priority)
**Estimated Time**: 4-6 hours
**Impact**: Major functional area redesign
**[`pools.html`](projectmycelium/src/views/dashboard/pools.html) Transformation Plan:**
1. **Page Title & Navigation**:
```html
<!-- Before -->
{% block title %}ThreeFold Dashboard - TFP Pools{% endblock %}
<!-- After -->
{% block title %}ThreeFold Dashboard - Credits Exchange{% endblock %}
```
2. **Pool Cards Redesign**:
```html
<!-- Before -->
<h5 class="mb-0">TFP - FIAT Pool</h5>
<span class="fw-bold exchange-rate">1 TFP = 0.1 USD</span>
<!-- After -->
<h5 class="mb-0">Credits - FIAT Exchange</h5>
<span class="fw-bold exchange-rate">1 Credit = $1.00 USD</span>
```
3. **JavaScript Function Updates**:
```javascript
// Before
async function handleBuyTFP() { ... }
async function handleSellTFP() { ... }
// After
async function handleBuyCredits() { ... }
async function handleSellCredits() { ... }
```
4. **Modal Updates**: All 6 modals need title and content updates
5. **Chart Updates**: All Chart.js configurations need label updates
#### Phase 3: Settings & Navigation (Low Priority)
**Estimated Time**: 1 hour
**Impact**: Consistency and completeness
1. **[`settings.html`](projectmycelium/src/views/dashboard/settings.html)**:
- Update currency dropdown options
- Update explanatory text
2. **[`layout.html`](projectmycelium/src/views/dashboard/layout.html)**:
- Update navigation menu item
#### Phase 4: Reports & Documentation (Lowest Priority)
**Estimated Time**: 1-2 hours
**Impact**: Professional completeness
1. Update service request reports and invoices
2. Update any remaining documentation references
### Technical Implementation Guidelines
#### 1. Search & Replace Patterns
```bash
# Safe patterns to replace:
"TFP/month" → "$/month"
"TFP/hour" → "$/hour"
"TFP Available" → "Credits Available"
"Monthly TFP Usage" → "Monthly Credits Usage"
"TFP Usage Trend" → "Credits Usage Trend"
# Complex patterns requiring manual review:
"TFP" in JavaScript variable names
"TFP" in function names
"TFP" in API endpoint references
```
#### 2. Amount Display Standardization
```html
<!-- Standard Credits display pattern -->
<span>${{ amount | format_decimal(precision=2) }}</span>
<!-- For rates/pricing -->
<span>${{ rate | format_decimal(precision=2) }}/hour</span>
```
#### 3. JavaScript Updates
```javascript
// Update variable names
const tfpAmount = ... → const creditsAmount = ...
// Update display logic
`${amount} TFP` → `$${amount.toFixed(2)}`
// Update API calls (if any remaining)
'/api/wallet/buy-tfp' → '/api/wallet/buy-credits'
```

# OpenRouter-Inspired Marketplace Implementation Status
## Project Overview
This document provides a comprehensive status update on implementing OpenRouter-inspired marketplace enhancements for the ThreeFold marketplace. The goal is to add streamlined "buy now" capabilities and improved wallet management while preserving all existing cart-based functionality.
## Target Features
### 1. Instant Purchase System
- **Goal**: Add "Buy Now" buttons alongside existing "Add to Cart" buttons
- **Requirements**: One-click purchasing that bypasses cart for immediate transactions
- **Integration**: Must work with existing session management and wallet system
### 2. Enhanced Wallet Management
- **Goal**: Easy TFP wallet funding with direct USD input
- **Requirements**:
- Quick top-up functionality with preset amounts ($10, $25, $50, $100)
- User-configurable currency preferences (USD, TFP, CAD, EUR)
- USD as default display currency
- Real-time wallet balance in navbar
### 3. OpenRouter-Style Navigation
- **Goal**: Replace simple "Hello, USERNAME" with feature-rich dropdown
- **Requirements**:
- Wallet balance display in navbar
- Quick access to wallet management
- Settings and logout options
### 4. Currency System Enhancement
- **Goal**: Support multiple display currencies while keeping TFP as base
- **Requirements**:
- Real-time currency conversion
- User preference storage
- Marketplace price display in preferred currency
## Implementation Status
### ✅ Completed Components
#### Core Services
- **NavbarService**: Dropdown menu data management using builder pattern
- **InstantPurchaseService**: Buy-now functionality with existing service patterns
- **CurrencyService Extensions**: User preference handling and TFP display support
- **UserPersistence Extensions**: Added `display_currency` and `quick_topup_amounts` fields
#### API Endpoints
- `POST /api/wallet/instant_purchase` - Process immediate purchases
- `POST /api/wallet/quick_topup` - Handle preset amount top-ups
- `GET /api/navbar/dropdown-data` - Fetch dropdown menu data
- `POST /api/user/currency` - Save currency preferences
#### Frontend Enhancements
- **base.html**: OpenRouter-style navbar dropdown with wallet integration
- **wallet/index.html**: Enhanced with quick top-up UI and currency selection
- **marketplace templates**: Buy-now buttons alongside cart functionality
- **settings.html**: Currency preferences tab with form handling
#### Data Model Extensions
```rust
// UserPersistentData additions
pub struct UserPersistentData {
// ... existing fields
pub display_currency: Option<String>,
pub quick_topup_amounts: Option<Vec<Decimal>>,
}
// Order system enhancements
pub enum PurchaseType {
Cart,
Instant,
}
```
### ✅ Fixed Issues
#### 1. Navbar Wallet Links
- **Issue**: Links went to non-existent `/wallet` routes
- **Fix**: Updated to correct `/dashboard/wallet` routes in base.html
#### 2. Buy Now Button JavaScript
- **Issue**: Buttons did nothing due to incorrect API endpoint
- **Fix**: Corrected endpoint path and redirect URLs in base.html
#### 3. Marketplace Currency Display
- **Issue**: compute_resources method wasn't using currency conversion
- **Fix**: Updated to use proper `create_price` conversion like other marketplace sections
### 🔧 Current Issues
#### 1. Template Rendering Error
```
[2025-07-31T03:08:28Z ERROR threefold_marketplace::utils] Template rendering error: Failed to render 'dashboard/settings.html'
```
- **Cause**: Likely missing template variables or syntax errors in settings.html
- **Impact**: Settings page not accessible
- **Priority**: High - blocks currency preference functionality
#### 2. Buy TFP Redirect Issue
- **Issue**: "Buy TFP" still redirects to TFP pool page instead of opening popup
- **Expected**: Should open modal popup in wallet page
- **Current**: Redirects to `/dashboard/pools`
- **Priority**: Medium - affects user experience
### 🏗️ Architecture Decisions
#### Currency System
- **Base Currency**: TFP remains fundamental for all calculations
- **Display Currency**: User-configurable preference for UI display
- **Conversion Logic**: Real-time conversion between TFP and display currencies
- **Default**: USD as default display currency
#### Service Layer Pattern
All new services follow existing builder pattern:
```rust
let service = ServiceName::builder()
.with_option(value)
.build()?;
```
#### Backward Compatibility
- All existing cart functionality preserved
- Existing API endpoints unchanged
- Database schema extensions only (no breaking changes)
- Template inheritance maintained
## Next Steps
### Immediate Priorities
1. **Fix Template Rendering Error**
- Debug settings.html template syntax
- Ensure all required template variables are provided
- Test template compilation
2. **Fix Buy TFP Redirect**
- Investigate where Buy TFP button is defined
- Ensure it opens modal instead of redirecting
- Test popup functionality
3. **Integration Testing**
- Test all marketplace sections with currency conversion
- Verify buy-now functionality across different product types
- Test currency preference saving and loading
### Testing Checklist

# OpenRouter-Inspired Marketplace Enhancement Plan
## Overview
This document outlines the implementation plan for enhancing the Project Mycelium with OpenRouter-inspired payment features while maintaining all existing functionality. The goal is to add streamlined "buy now" capabilities and improved wallet management alongside the current cart-based shopping experience.
## Current System Analysis
### Architecture Patterns
- **Builder Pattern**: Services use `ServiceName::builder().build()` pattern
- **Service Layer**: Clean separation with dedicated services (CurrencyService, WalletController, etc.)
- **Controller Pattern**: RESTful endpoints with JSON responses
- **Template Engine**: Tera templating with context-based rendering
- **Session Management**: Actix-web sessions for user state
- **Persistence**: UserPersistence service for data management
### Current Currency System
- **Base Currency**: TFP (ThreeFold Points)
- **Exchange Rate**: 1 TFP = 0.1 USD (configurable)
- **Display Options**: Currently supports multiple currencies (USD, EUR, TFT, PEAQ)
- **User Preferences**: Currency preferences stored per user
### Current Purchase Flow
1. Browse marketplace → Add to cart → Checkout → Purchase
2. TFP purchase via wallet page or TFP pools
3. TFP pools support trading: TFP/Fiat, TFP/TFT, TFP/PEAQ
## Enhancement Goals
### 1. Currency Display Improvements
- **Default Currency**: Set USD as default display currency for new users
- **TFP Display Option**: Add TFP as a display currency choice alongside fiat currencies
- **User Choice**: Users can choose any supported currency (TFP, USD, CAD, EUR, etc.) for price display
- **Internal Processing**: All transactions remain TFP-based internally
### 2. OpenRouter-Style Navbar
Replace simple "Hello, USERNAME" with dropdown menu containing:
- User name/email
- Current wallet balance in user's preferred display currency
- "Top Up Wallet" / "Buy Credits" quick action
- Settings link

# Project Mycelium Credits System - Complete Refactor Plan
## Overview
This document outlines the complete transformation of the Project Mycelium from a TFP-based system to a simplified USD credits system inspired by OpenRouter's user experience. This is a major refactor that will become the new standard for the marketplace.
## Current State vs Desired State
### Current State (TFP System)
- **Currency**: TFP (ThreeFold Points) with 1 TFP = 0.1 USD
- **Complexity**: Multi-currency display (USD, EUR, CAD, TFP)
- **Trading**: Complex Pools page with TFP/TFT/PEAQ trading
- **UX**: Crypto-like terminology and fractional pricing
- **Purchase Flow**: Add to cart → checkout (Buy Now exists but broken)
- **Top-up**: Manual wallet top-up with currency conversion
- **Pricing**: Products cost 50 TFP for $5 item (confusing)
### Desired State (USD Credits System)
- **Currency**: USD Credits with 1 Credit = $1 USD
- **Simplicity**: Pure USD pricing throughout
- **No Trading**: Hide Pools page (keep code for future)
- **UX**: Clean "credits" terminology like mainstream SaaS
- **Purchase Flow**: Seamless Buy Now + Add to Cart options
- **Auto Top-up**: OpenRouter-style automatic credit purchasing
- **Pricing**: Products cost $5 for $5 item (intuitive)
## Detailed Transformation Plan
### 1. Currency System Transformation
#### Current TFP System
```rust
// Current: 1 TFP = 0.1 USD
let tfp_amount = usd_amount * 10; // $5 = 50 TFP
```
#### New USD Credits System
```rust
// New: 1 Credit = 1 USD
let credit_amount = usd_amount; // $5 = 5 Credits
```
#### Implementation Changes
- **Currency Service**: Update exchange rate from 0.1 to 1.0
- **Display Logic**: Remove TFP terminology, use "Credits" and "$" symbols
- **Database**: Store amounts as USD credits (multiply existing TFP by 10)
- **API Responses**: Return credit amounts instead of TFP amounts
### 2. User Interface Transformation
#### Navigation & Terminology
- **Backend/Routes**: Keep "Wallet" terminology (`/dashboard/wallet`)
- **UI Labels**: Use "Credits" terminology in content
- **Example**: Sidebar shows "Wallet", page content shows "Buy Credits"
#### Wallet Page Changes
**Before:**
```
Wallet Balance: 150.5 TFP
≈ $15.05 USD
Quick Top-up:
- Add 100 TFP ($10)
- Add 250 TFP ($25)
```
**After:**
```
Credit Balance: $25.00
Buy Credits:
- Add $10 Credits
- Add $25 Credits
- Add $50 Credits
- Custom Amount: $____
Auto Top-up:
☐ Enable Auto Top-up
When credits are below: $10
Purchase this amount: $25
```
#### Marketplace Pricing
**Before:**
```
VM Instance: 50.0 TFP/month
≈ $5.00 USD/month
```
**After:**
```
VM Instance: $5.00/month
```
### 3. Auto Top-up Implementation
#### OpenRouter-Style Configuration
```
Auto Top-up Settings:
☐ Enable auto top-up
When credits are below:
$ [10]
Purchase this amount:
$ [25]
Payment Method: [Credit Card ****1234] [Change]
[Save Settings]
```
#### Technical Implementation
```rust
#[derive(Debug, Serialize, Deserialize)]
pub struct AutoTopUpSettings {
pub enabled: bool,
pub threshold_amount: Decimal, // USD amount
pub topup_amount: Decimal, // USD amount
pub payment_method_id: String,
pub daily_limit: Option<Decimal>,
pub monthly_limit: Option<Decimal>,
}
```
#### Auto Top-up Flow
1. **Trigger Check**: Before any purchase, check if balance < threshold
2. **Automatic Purchase**: If enabled, automatically buy credits
3. **Fallback**: If auto top-up fails, prompt user for manual top-up
4. **Limits**: Respect daily/monthly spending limits for security
### 4. Buy Now Functionality Fix
#### Current Issue
- Buy Now buttons exist in marketplace templates
- JavaScript event handlers are missing
- Backend instant purchase API exists but not connected
#### Solution Implementation
```javascript
// Fix: Add proper event handlers
document.addEventListener('DOMContentLoaded', function() {
document.querySelectorAll('.buy-now-btn').forEach(button => {
button.addEventListener('click', async function() {
const productId = this.dataset.productId;
const productName = this.dataset.productName;
const unitPrice = parseFloat(this.dataset.unitPrice);
await buyNow(productId, productName, 'compute', 1, unitPrice);
});
});
});
// Enhanced buyNow function with auto top-up integration
window.buyNow = async function(productId, productName, category, quantity, unitPrice) {
try {
// Check balance and trigger auto top-up if needed
const affordabilityCheck = await fetch(`/api/wallet/check-affordability?amount=${unitPrice * quantity}`);
const result = await affordabilityCheck.json();
if (!result.can_afford) {
const autoTopUpResult = await handleInsufficientBalance(result.shortfall_info);
if (!autoTopUpResult.success) return;
}
// Proceed with instant purchase
const purchaseResponse = await fetch('/api/wallet/instant-purchase', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
product_id: productId,
product_name: productName,
quantity: quantity,
unit_price_usd: unitPrice
})
});
const purchaseResult = await purchaseResponse.json();
handlePurchaseResult(purchaseResult);
} catch (error) {
console.error('Purchase failed:', error);
showErrorMessage('Purchase failed. Please try again.');
}
};
```
### 5. Burn Rate Tracking
#### User Dashboard Enhancement
```
Credit Usage Overview:
Current Balance: $47.50
Monthly Burn Rate: $23.00/month
├── VM-Production: $15.00/month
├── Gateway-EU: $5.00/month
└── Storage-Backup: $3.00/month
Projected Balance in 30 days: $24.50
⚠️ Consider enabling auto top-up
Auto Top-up Status: ✅ Enabled
Next top-up triggers at: $10.00
```
#### Implementation
```rust
#[derive(Debug, Serialize)]
pub struct BurnRateAnalysis {
pub monthly_burn_rate: Decimal,
pub daily_burn_rate: Decimal,
pub deployments: Vec<DeploymentBurnRate>,
pub projected_balance_30_days: Decimal,
pub days_until_empty: Option<u32>,
}
#[derive(Debug, Serialize)]
pub struct DeploymentBurnRate {
pub deployment_id: String,
pub deployment_name: String,
pub monthly_cost: Decimal,
pub daily_cost: Decimal,
pub status: String,
}
```
### 6. Pools Page Strategy
#### Current Pools Functionality
- TFP ↔ USD/EUR/CAD trading
- TFP ↔ TFT/PEAQ crypto trading
- Staking with marketplace benefits
- Complex liquidity pool management
#### New Strategy: Hide but Preserve
- **Hide**: Remove Pools from main navigation
- **Preserve**: Keep all code and functionality intact
- **Access**: Add hidden route for future use
- **Rationale**: Credits system eliminates need for trading, but keep for potential future features
#### Implementation
```rust
// Hide pools route from main navigation
// Comment out in routes/mod.rs:
// .route("/dashboard/pools", web::get().to(DashboardController::pools))
// Keep as hidden route for admin/future use:
// .route("/dashboard/pools-advanced", web::get().to(DashboardController::pools))
```
### 7. Database Schema Updates
#### UserPersistentData Changes
```rust
pub struct UserPersistentData {
// Change from TFP to USD credits
pub wallet_balance: Decimal, // Now in USD (multiply existing TFP by 10)
// Remove TFP-specific fields
// pub display_currency: Option<String>, // Remove - always USD now
// Add auto top-up settings
pub auto_topup_settings: Option<AutoTopUpSettings>,
// Update transaction amounts to USD
pub transactions: Vec<Transaction>,
// Keep existing fields
pub user_email: String,
pub services: Vec<Service>,
// ... other fields unchanged
}
```
#### Transaction Model Updates
```rust
pub enum TransactionType {
// Update existing types to use USD
Purchase { product_id: String, amount_usd: Decimal },
TopUp { amount_usd: Decimal, payment_method: String },
// Add new auto top-up type
AutoTopUp {
triggered_by_purchase: Option<String>,
threshold_amount: Decimal,
amount_usd: Decimal,
payment_method: String
},
// Keep existing types but update amounts to USD
Transfer { to_user: String, amount_usd: Decimal },
Earning { source: String, amount_usd: Decimal },
}
```
### 8. API Endpoint Updates
#### New Auto Top-up Endpoints
```rust
// Auto top-up configuration
POST /api/wallet/auto-topup/configure
GET /api/wallet/auto-topup/status
POST /api/wallet/auto-topup/trigger
// Enhanced purchase with auto top-up
POST /api/wallet/purchase-with-topup
GET /api/wallet/burn-rate-analysis
```
#### Updated Existing Endpoints
```rust
// Wallet info now returns USD credits
GET /api/wallet/info
// Response:
{
"balance": 25.00,
"currency": "USD",
"auto_topup_enabled": true,
"auto_topup_threshold": 10.00
}
// Navbar data with credits
GET /api/navbar/dropdown-data
// Response:
{
"wallet_balance_formatted": "$25.00",
"display_currency": "USD",
"auto_topup_enabled": true,
"auto_topup_status": "Active"
}
```
### 9. Migration Strategy
#### Data Migration
```rust
// Convert existing TFP balances to USD credits
fn migrate_tfp_to_usd_credits(user_data: &mut UserPersistentData) {
// 1 TFP = 0.1 USD, so multiply by 10 to get USD credits
user_data.wallet_balance = user_data.wallet_balance * dec!(10);
// Update all transaction amounts
for transaction in &mut user_data.transactions {
match &mut transaction.transaction_type {
TransactionType::Purchase { amount, .. } => *amount *= dec!(10),
TransactionType::TopUp { amount, .. } => *amount *= dec!(10),
// ... update other transaction types
}
}
}
```
#### Deployment Strategy
1. **Phase 1**: Deploy new code with migration logic
2. **Phase 2**: Run migration script on user data
3. **Phase 3**: Update frontend templates and JavaScript
4. **Phase 4**: Hide pools page and update navigation
### 10. User Experience Flow
#### New User Journey
1. **Registration**: User creates account
2. **Wallet Setup**: Sees "$0.00" credit balance
3. **Browse Marketplace**: Products priced in clear USD amounts
4. **First Purchase**:
- Clicks "Buy Now" on $5 VM
- Prompted to "Buy Credits" (insufficient balance)
- Buys $25 credits via credit card
- Purchase completes automatically
5. **Auto Top-up Setup**:
- Configures auto top-up: "When below $10, buy $25"
- Enables for seamless future purchases
6. **Ongoing Usage**:
- Monitors burn rate dashboard
- Auto top-up handles low balances
- Focuses on using services, not managing credits
#### Purchase Flow Comparison
**Before (TFP):**
```
1. See "VM: 50 TFP/month (≈$5 USD)"
2. Check wallet: "15.5 TFP (≈$1.55)"
3. Calculate: Need 34.5 more TFP
4. Go to wallet, buy TFP in preferred currency
5. Convert currency to TFP
6. Return to marketplace
7. Add to cart and checkout
```
**After (USD Credits):**
```
1. See "VM: $5.00/month"
2. Click "Buy Now"
3. Auto top-up triggers: Buys $25 credits
4. Purchase completes: VM deployed
5. Balance: $20.00 remaining
```

<p>You'll need to add USD credits to your wallet</p>
<li>Buy credits through the simple top-up interface</li>
```
**Main Documentation Index:**
```html
<!-- Before -->
<td>TFP transferred based on resource utilization</td>
<td>TFP transferred based on hardware value</td>
<!-- After -->
<td>USD credits charged based on resource utilization</td>
<td>USD credits charged based on hardware value</td>
```
#### 3. Navigation Updates
**Documentation Sidebar (`/docs/layout.html`):**
```html
<!-- Before -->

# "TFP" → "USD credits" or "credits"
# "ThreeFold Points" → "USD credits"
# "0.1 USD" → "1 USD"
# "50 TFP" → "$5.00"
```
**URL Redirects:**
```rust
// Add redirect for old TFP documentation
.route("/docs/tfp", web::get().to(|| async {
HttpResponse::MovedPermanently()
.append_header(("Location", "/docs/credits"))
.finish()
}))
```

# Enhanced Project Mycelium Refactor Plan - Phase 2
## Overview
This document outlines the enhanced implementation plan for the Project Mycelium based on the successful progress from Phase 1 and incorporates OpenRouter-inspired UX improvements. The goal is to create an optimal user experience with streamlined credit management, auto top-up functionality, and improved Buy Now capabilities.
## Current System Analysis
### Existing Implementation Status
- **Currency System**: TFP-based with 1 TFP = 0.1 USD exchange rate
- **Navbar**: OpenRouter-style dropdown already implemented with wallet balance display
- **Wallet Controller**: Comprehensive implementation with instant purchase and quick top-up
- **Buy Now Functionality**: Partially implemented but currently non-functional
- **Currency Preferences**: Fully implemented with USD, EUR, CAD, TFP options
- **Quick Top-up Amounts**: Configurable user preferences already in place
### Key Findings from Code Analysis
1. **Strong Foundation**: The existing architecture already supports most requested features
2. **Naming Convention**: Current system uses "Wallet" terminology throughout codebase
3. **Buy Now Issue**: Frontend buttons exist but lack proper event handlers
4. **Auto Top-Up**: Not yet implemented but infrastructure is ready
5. **Pools Integration**: Currently separate from main wallet flow
## Enhanced Requirements Analysis
### User Feedback Integration
Based on your requirements, here are the key changes needed:
#### 1. Currency Rebranding
- **Change**: TFP → TFC (ThreeFold Credits)
- **Exchange Rate**: 10 TFC = 1 USD (instead of 1 TFP = 0.1 USD)
- **Impact**: Requires currency service updates and display formatting changes
#### 2. Naming Convention Decision
**Recommendation**: Keep "Wallet" terminology
- **Rationale**: Changing to "Credits" would require extensive route and controller refactoring
- **Alternative**: Update UI labels while maintaining backend naming
- **Benefit**: Maintains existing functionality while improving UX
#### 3. Auto Top-Up Implementation
- **Feature**: OpenRouter-style auto top-up with configurable thresholds
- **Integration**: Seamless with existing quick top-up infrastructure
- **User Control**: Toggle on/off with customizable amounts and triggers
#### 4. Buy Now Functionality Fix
- **Issue**: Frontend buttons exist but lack proper JavaScript event handlers
- **Solution**: Implement missing event listeners and API integration
- **Enhancement**: Integrate with auto top-up for insufficient balance scenarios
## Technical Implementation Plan
### Phase 2A: Currency System Enhancement (Week 1)
#### 2A.1 Currency Service Updates
```rust
// File: src/services/currency.rs
impl CurrencyService {
pub fn get_tfc_exchange_rate() -> Decimal {
dec!(0.1) // 10 TFC = 1 USD, so 1 TFC = 0.1 USD
}
pub fn convert_usd_to_tfc(usd_amount: Decimal) -> Decimal {
usd_amount * dec!(10) // 1 USD = 10 TFC
}
pub fn convert_tfc_to_usd(tfc_amount: Decimal) -> Decimal {
tfc_amount / dec!(10) // 10 TFC = 1 USD
}
}
```
#### 2A.2 Display Updates
- Update all "TFP" references to "TFC" in templates
- Modify currency formatting to show TFC amounts
- Update exchange rate calculations throughout the system
#### 2A.3 Database Migration Strategy
- **Backward Compatibility**: Maintain existing TFP data structure
- **Display Layer**: Convert TFP to TFC for display (multiply by 10)
- **New Transactions**: Store in TFC format going forward
### Phase 2B: Auto Top-Up Implementation (Week 2)
#### 2B.1 Auto Top-Up Data Models
```rust
// File: src/models/user.rs
#[derive(Debug, Serialize, Deserialize, Clone)]
pub struct AutoTopUpSettings {
pub enabled: bool,
pub threshold_amount: Decimal, // In TFC
pub topup_amount: Decimal, // In TFC
pub payment_method: String,
pub currency: String, // User's preferred currency for payment
pub last_topup: Option<DateTime<Utc>>,
pub daily_limit: Option<Decimal>,
pub monthly_limit: Option<Decimal>,
}
```
#### 2B.2 Auto Top-Up Service
```rust
// File: src/services/auto_topup.rs
pub struct AutoTopUpService {
currency_service: CurrencyService,
payment_service: PaymentService,
}
impl AutoTopUpService {
pub async fn check_and_execute_topup(&self, user_email: &str) -> Result<Option<TopUpResult>, String> {
// Check if auto top-up is enabled and threshold is met
// Execute top-up if conditions are satisfied
// Return result with transaction details
}
pub fn should_trigger_topup(&self, current_balance: Decimal, settings: &AutoTopUpSettings) -> bool {
settings.enabled && current_balance < settings.threshold_amount
}
}
```
#### 2B.3 Integration Points
- **Purchase Flow**: Check auto top-up before insufficient balance errors
- **Wallet Page**: Auto top-up configuration UI
- **Background Service**: Periodic balance checks for active users
### Phase 2C: Buy Now Functionality Fix (Week 2)

```javascript
// File: src/views/base.html (enhanced buyNow function)
window.buyNow = async function(productId, productName, productCategory, quantity, unitPriceTfc, providerId, providerName, specifications = {}) {
try {
// Check if auto top-up is enabled and balance is sufficient
const affordabilityCheck = await fetch(`/api/wallet/check-affordability?amount=${unitPriceTfc * quantity}`);
const affordabilityResult = await affordabilityCheck.json();
if (!affordabilityResult.can_afford && affordabilityResult.shortfall_info) {
// Trigger auto top-up if enabled, otherwise prompt user
const autoTopUpResult = await handleInsufficientBalance(affordabilityResult.shortfall_info);
if (!autoTopUpResult.success) {
return; // User cancelled or auto top-up failed
}
}
// Proceed with purchase
const response = await fetch('/api/wallet/instant-purchase', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
product_id: productId,
product_name: productName,
product_category: productCategory,
quantity: quantity,
unit_price_tfc: unitPriceTfc,
provider_id: providerId,
provider_name: providerName,
specifications: specifications
})
});
const result = await response.json();
handlePurchaseResult(result);
} catch (error) {
console.error('Buy now error:', error);
showErrorMessage('Failed to process purchase. Please try again.');
}
};
```
#### 2C.2 Event Handler Registration
```javascript
// File: marketplace templates
document.addEventListener('DOMContentLoaded', function() {
// Register Buy Now button event handlers
document.querySelectorAll('.buy-now-btn').forEach(button => {
button.addEventListener('click', function() {
const productId = this.dataset.productId;
const productName = this.dataset.productName;
const unitPrice = parseFloat(this.dataset.unitPrice);
const currency = this.dataset.currency;
// Convert to TFC if needed
const unitPriceTfc = currency === 'TFC' ? unitPrice : convertToTfc(unitPrice, currency);
buyNow(productId, productName, 'compute', 1, unitPriceTfc, 'provider', 'Provider Name');
});
});
});
```

---
## 🔍 **Debugging Guide**
### **Common Error Patterns and Solutions**:
1. **Missing .build() calls**:
- Error: `expected HttpResponse, found Result<HttpResponse, Error>`
- Solution: Add `.build()` to end of ResponseBuilder chain
2. **Content-type method not found**:
- Error: `no method named 'content_type' found for struct 'ResponseBuilder'`
- Solution: Convert to `HttpResponse::Ok().content_type("application/json").json(data)`
3. **Found method not found**:
- Error: `no function or associated item named 'found' found for struct 'ResponseBuilder'`
- Solution: Convert to `HttpResponse::Found().append_header(("Location", "/path")).finish()`
4. **Template rendering type mismatch**:
- Error: `mismatched types` for render_template calls
- Solution: Wrap with `Ok(render_template(...))`
---
**This prompt provides complete context for the final phase of ResponseBuilder migration, building on the major achievement of completing the Dashboard controller migration and focusing on the remaining compilation error resolution to achieve zero compilation errors across the entire codebase.**

# Project Mycelium - Complete Mock Data Removal Plan
**Date**: 2025-08-14
**Task**: Remove all code-based mock data and enforce persistent-only data
**Status**: Implementation Active
## Overview
Despite the architecture documentation claiming "100% Mock Data Elimination," extensive mock data infrastructure remains throughout the system. This plan systematically removes all 129+ mock patterns identified while ensuring the application continues to function with persistent storage only.
## Current Mock Data Patterns Identified
### Critical Mock Infrastructure:
- [ ] **MockUserData Factory Methods**: `user1()` through `user5()` in `src/models/user.rs`
- [ ] **MockDataService Singleton**: Complete service in `src/services/mock_data.rs`
- [ ] **User.mock_data Field**: Extensively used across controllers
- [ ] **MockPaymentGateway**: Mock payment processing in `src/services/order.rs`
- [ ] **Mock-dependent Controllers**: Rental, Pool, Dashboard controllers
- [ ] **Mock Initialization**: User persistence still initializes with mock data
## Phase 1: Infrastructure & Data Model Changes ✅

- [ ] Add any follow-up persistence improvements needed
**Files to modify:**
- `docs/dev/design/current/marketplace-todo.md`
## Implementation Strategy
### Critical Success Factors:
1. **Backward Compatibility**: All persistent structures must have `#[serde(default)]`
2. **Default Values**: Replace mock arrays with sensible defaults (`Vec::new()`, `None`, `0`)
3. **Error Handling**: Add proper error handling for missing data instead of mock fallbacks
4. **Gradual Migration**: Keep User.mock_data field optional during transition
5. **Testing**: Verify each phase before proceeding to next
### Risk Mitigation:
- **Compilation Safety**: Check `cargo check` after each major change
- **Data Safety**: Ensure existing user_data/ JSON files continue to work
- **Functionality Safety**: Test core flows after each controller update
- **Rollback Plan**: Git commits for each phase allow easy rollback
## Acceptance Criteria
- ✅ `cargo check` passes with zero compilation errors
- ✅ Application starts and runs with `APP_ENABLE_MOCKS=0`
- ✅ No code-based mock user factories remain in codebase
- ✅ Dashboard displays persistent data or proper empty states
- ✅ All marketplace flows function using persistent storage only
- ✅ No occurrences of mock patterns in grep search
- ✅ Architecture documentation reflects actual implementation
## Progress Tracking
This document will be updated with checkmarks (✅) as each section is completed during implementation.

# Project Mycelium Complete UX
## Introduction
We present the complete user experience for the Project Mycelium.
## User Experience
- Publicly available information
- A user can consult the docs at /docs
- A user can consult the privacy policy at /privacy
- A user can consult the Terms and Conditions at /terms
- A user can read about the marketplace at /about
- A user can contact ThreeFold by consulting the page /contact
- Registration and Login
- A user can register at /register
- Once registered they can log out and then log in at /login
- Purchases
- A non-logged in user can check the marketplace at /marketplace and add items to cart
- To buy an item, the user must be logged in and have enough credits
- Purchase UX
- A user can always buy a product or service in two ways
- They can Buy Now, or Add to Cart (then proceed to checkout and complete the purchase)
- A non-logged in user will have access to the cart at /cart
- If they then log in, the cart items will be added to their account's cart
- In the /cart page, they can clear cart or delete individual items in the cart
- If they try to edit the cart, a message appears telling them to log in to edit the cart
- A logged in user will have access to the cart at /dashboard/cart
- Then they add to cart, they can see their cart at /dashboard/cart
- In the /cart page, they can clear cart or delete individual items in the cart
- As a logged in user, they can edit the cart, e.g. click + to add more of that same item, or click - to remove that item
- A user can see all their purchases at /dashboard/orders
- A user can see their recent transactions at /dashboard/wallet Recent Transactions
- Credits
- A user can buy credits at /dashboard/wallet, Buy Credits
- A user can transfer credits to another user at /dashboard/wallet, Transfer Credits
- A user can set up Auto Top-Up Settings at /dashboard/wallet Auto Top-up Settings
- Thus if a user buys an app that costs e.g. 10 USD per month, they can set an automatic wallet top-up to never go below that number, ensuring their app will never run out of credits
- Marketplace
- In the marketplace, a user can search and filter items in different categories
- They can buy compute resources (slices) at /marketplace/compute
- They can reserve a complete node (server) at /marketplace/3nodes
- They can buy Mycelium gateways at /marketplace/gateways
- They can buy applications (solutions) at /marketplace/applications
- They can buy services at /marketplace/services
- Settings
- A user can change settings at /dashboard/settings
- They can
- Update the profile information (email can't be changed)
- Name
- Country
- Time Zone
- Change the password
- Set Up SSH Public Keys
- Update notification settings
- Security alerts
- Billing notifications
- System alerts (downtime, maintenance)
- Newsletter and product updates
- Dashboard Notifications
- Show alerts in dashboard
- Show update notifications
- Update their currency preferences
- They can decide to have the prices displayed in
- USD
- TFC
- EUR
- CAD
- Delete account
- When a user deletes their account, their data is still available on the marketplace backend for security, audit and legal purposes
- Dashboard UX and Provider+Consumer Interactions
- A user can see their dashboard overview activities at /dashboard
- A user can see their user profile and activities at /dashboard/user
- A user provoding resources to the grid (aka a farmer) at /dashboard/farmer
- There they can add resources, e.g. add a node to the marketplace which will be available for purchase by other users as slices (a node is distributed as slices)
- A user can become an app provider at /dashboard/app-provider by registering new applications
- When a user register an application
- The application is displayed publicly at /marketplace/applications
- The application is shown at the app provider dashboard /dashboard/app-provider at the table My Published Applications
- When another user buys that app
- The app provider will see that info at the table /dashboard/app-provider Active Deployments
- The app purchaser will see the app info at /dashboard/user My Applications
- A user can become a service provider at /dashboard/service-provider by registering new services
- When a user register a service
- The service is displayed publicly at /marketplace/services
- The service is shown at the service provider dashboard /dashboard/service-provider at the table My Service Offerings
- When another user buys that service
- The service provider will see that info at the table /dashboard/service-provider Service Requests
- There are 3 stages to this service request from the service provider POV
- Open
- In Progress
- Completed
- The service purchaser will see the service info at /dashboard/user My Service Bookings
- A user can become a resource provider by adding nodes and thus resources to the marketplace at /dashboard/farmer
- They can Add Nodes
- Then it fetches the nodes on the ThreeFold Grid and distribute the node into slices
- Then the slices are can be seen publicly at /marketplace/compute
- Any user can then purchase slices from that farmer and access the slices
- Products
- Farmers at the core offer compute resources (slices) to the marketplace.
- On their end, farmers host nodes on the threefold grid. nodes are split into slices.
- Users can use slices for individual VMs, or for Kubernetes cluster
- The UI is intuitive
- .html_template_tests
- Apps can be self-managed and managed
- An app is at its core a slice (VM or Kubernetes cluster) with an app on top
- for self-managed node, users can set their SSH public key, they set it in /dashboard/settings SSH Keys page
- for managed node, users will have access to the credentials on their marketplace dashboard in /dashboard/user page at the section of the app/product they rent/bought
---
- we want to have tests to check and confirm that the UX of the marketplace is as should be
- thus, there should be a series of test for the UX above
- we don't need any other test and we should have the tests mentioned above in an isolated section, e.g. not shared with other tests
- this ensures that the tests are not affected by other tests

> This content should be used as a prompt for the AI assistant to guide the developer in implementing the Project Mycelium. It should not be used directly. We copy paste this into an AI coder. Do not use this file for the Marketplace directly.
Project Mycelium – Session Prompt
Objective
- Use the single authoritative file [docs/dev/design/current/projectmycelium-roadmap.md](cci:7://file:///Users/pmcomp/Documents/code/ai/code-25-08-17-01-mp/projectmycelium/docs/dev/design/current/projectmycelium-roadmap.md:0:0-0:0) to:
1) Analyze current state and gaps.
2) Propose the most impactful next task(s) to move toward 100% completion.
3) Implement and verify changes (code/docs).
4) Update the roadmap with results and define the next step.
5) Commit and push the changes.
Inputs
- Roadmap file (authoritative): [docs/dev/design/current/projectmycelium-roadmap.md](cci:7://file:///Users/pmcomp/Documents/code/ai/code-25-08-17-01-mp/projectmycelium/docs/dev/design/current/projectmycelium-roadmap.md:0:0-0:0)
- Current local time: {{local_time}}
Guardrails (must follow)
- CSP: no inline handlers; per-field JSON hydration (`| json_encode` with named-arg defaults); only top-level `{% block head %}` and `{% block scripts %}`.
- ResponseBuilder: all API responses wrapped; frontend must `const data = result.data || result;`.
- Persistent-only runtime: no mocks in prod paths; verify `APP_ENABLE_MOCKS=0`.
- Currency: USD base; TFC supported; insufficient funds must be HTTP 402 with canonical JSON error.
- Logging: zero `log::` in main/dev branches (temporary logs only in feature branches and removed before merge).
Session Steps
1) Analyze
- Read the roadmap; confirm “Current state”, “Gaps”, and immediate/near-term items.
- Choose the highest-impact, lowest-risk next task that unblocks others (e.g., mock removal, 402 unification, dashboard persistence, SLA list, cart flow).
2) Plan
- Propose 1–3 concrete tasks with:
- Scope, files/routes/templates to touch (e.g., `src/controllers/*.rs`, `src/static/js/*.js`, `src/views/**/*.html`).
- Acceptance criteria and tests.
- Expected side-effects (if any).
3) Execute
- Make minimal, correct edits; imports at top; adhere to builder pattern + ResponseBuilder.
- Maintain CSP compliance and persistent-only data usage.
4) Verify
- Run focused checks (fixtures mode; mocks disabled).
- Validate acceptance criteria; outline manual verification steps if needed.
5) Document
- Update [docs/dev/design/current/projectmycelium-roadmap.md](cci:7://file:///Users/pmcomp/Documents/code/ai/code-25-08-17-01-mp/projectmycelium/docs/dev/design/current/projectmycelium-roadmap.md:0:0-0:0):
- Refresh “Last Updated”.
- Add a brief “Changes in this session” note in relevant sections (state/gaps/roadmap).
- Append to Troubleshooting/Dashboard Backlog/.env/Tests/CSP appendices if needed.
- Ensure archived docs aren’t referenced.
6) Git
- Use a short, scoped branch name per task (e.g., `feat/unify-402-insufficient-funds`).
- Commit referencing the roadmap section updated.
- Commands (from repo root):
```
git add -A
git commit -m "roadmap: <short summary> — update doc + implement <feature/fix>"
git push
```
- Optionally open a PR targeting the correct branch (e.g., development).
7) Next Step
- Propose the next most impactful, bite-sized task with acceptance criteria.
Output Format (return exactly these sections)
- Findings: brief analysis of current state vs roadmap.
- Proposed Tasks: 1–3 items with scope + acceptance criteria.
- Plan: exact edits to perform (files/functions/routes/templates).
- Execution: commands/tests run and results (summarized).
- Roadmap Update: exact lines/sections updated in [projectmycelium-roadmap.md](cci:7://file:///Users/pmcomp/Documents/code/ai/code-25-08-17-01-mp/projectmycelium/docs/dev/design/current/projectmycelium-roadmap.md:0:0-0:0).
- Git: branch/commit/push (and PR if applicable).
- Next Step: 1 task with acceptance criteria.
- Risks/Notes: any issues or follow-ups.
Constraints
- Prefer incremental, reversible changes.
- Don’t introduce/enable mocks unless explicitly testing mock mode.
- Keep the roadmap as the only source of truth; fix any residual references to archived docs if found.
Optional Checks (run when relevant)
- Search for mock remnants: `Mock|mock_|demo_|sample_`.
- Ensure insufficient funds uses HTTP 402 + canonical JSON across flows.
- Ensure dashboards unwrap ResponseBuilder and hydrate via JSON script blocks.
- Validate CSP: no inline handlers; only top-level head/scripts blocks; external JS in `src/static/js/`.

# Project Mycelium - Complete Vision & Roadmap
**Last Updated:** 2025-08-20 21:25:00 (EST)
**Purpose:** Complete architectural vision, current state, and actionable roadmap for finalizing the Project Mycelium.
## 🎯 Project Status: Ready for Feature Development
**Compilation Status:** ✅ Zero errors achieved - codebase compiles successfully
**Data Migration:** ✅ Transitioned from mock to persistent data architecture
**Next Phase:** Runtime testing, feature completion, and production readiness
---
## 1. Architecture Vision (Target State)
### Core Design Principles
#### **Builder Pattern as Single Source of Truth**
- [`SessionDataBuilder`](src/services/session_data.rs), [`ConfigurationBuilder`](src/config/builder.rs), [`ResponseBuilder`](src/utils/response_builder.rs), [`ServiceFactory`](src/services/factory.rs) centralize construction and lifecycles
- All HTTP endpoints return via [`ResponseBuilder`](src/utils/response_builder.rs) with consistent JSON envelopes
#### **ResponseBuilder Envelope & Frontend Contract**
```json
{
"success": true|false,
"data": { ... },
"error"?: { ... }
}
```
- Frontend must always unwrap: `const data = result.data || result;` before accessing fields
#### **CSP-Compliant Frontend: External JS + JSON Hydration**
- **Zero inline scripts/handlers** - code lives in [`src/static/js/*.js`](src/static/js/) and is served under `/static/js/*`
- **Data hydration** via `<script type="application/json" id="...">` blocks
- **Individual field encoding**: Each field is JSON-encoded individually (server-side serializer)
- **Template structure**: Templates expose `{% block scripts %}` and `{% block head %}` at top level only
- **Static mapping**: Actix serves `/static/*` from `./src/static` (see `src/main.rs`)
#### **Persistent-Data-Only Runtime**
- **No mock data** in production code
- **Canonical user data model** persisted per user under [`./user_data/{email_encoded}.json`](user_data/) via [`UserPersistence`](src/services/user_persistence.rs)
- **All operations** (orders, services, wallet, products) read/written through persistence services
#### **Product Model: User-Owned SOT + Derived Catalog**
- **Products owned by provider users** in their persistent files
- **[`ProductService`](src/services/product.rs)** aggregates derived marketplace catalog
- **Category ID normalization** with optional dev TTL cache (disabled by default in prod)
#### **Currency System**
- **USD as base currency** with display currencies: USD/TFC/EUR/CAD (extensible)
- **TFC credits settle** at 1 TFC = 1 USD
- **Server-formatted amounts**: Server returns formatted display amounts and currency code
- **Frontend renders** without recomputing
#### **Unified Insufficient-Balance Contract**
- **Target**: HTTP 402 Payment Required for all insufficient funds cases
- **Canonical error payload** with `error.details` containing currency-aware amounts and deficit
---
## 2. Current Implementation State
### ✅ Completed Foundation
- **CSP externalization** complete across marketplace and dashboard
- **ResponseBuilder integration** applied across all controllers (100% coverage)
- **Orders & invoices** persisted under user data with HTML invoice view
- **Currency system** working with multi-currency display
- **Insufficient-funds responses** unified to HTTP 402 with canonical error envelope
- **Mock data elimination** completed - persistent-only architecture established
### ✅ Core Services Architecture
- **Authentication**: GitEa OAuth integration with user creation
- **Data Persistence**: [`UserPersistence`](src/services/user_persistence.rs) as single source of truth
- **Product Management**: [`ProductService`](src/services/product.rs) with category normalization
- **Order Processing**: Complete order lifecycle with invoice generation
- **Wallet Operations**: Multi-currency support with transaction history
### 🔧 Architecture Patterns Established
#### **Data Flow Pattern**
```rust
// Persistent data access pattern
let persistent_data = UserPersistence::load_user_data(&user_email)?;
// Direct usage of persistent data
persistent_data.wallet_balance_usd
```
#### **Transaction Pattern**
```rust
Transaction {
id: transaction_id,
user_id: user_email,
transaction_type: TransactionType::Purchase { product_id },
amount: amount_to_add,
currency: Some("USD".to_string()),
timestamp: chrono::Utc::now(),
status: TransactionStatus::Completed,
}
```
#### **ResponseBuilder Pattern**
```rust
ResponseBuilder::success()
.data(json!({ "products": products }))
.build()
```

- **Models**: [`src/models/`](src/models/) - Data structures and builders
- **Utils**: [`src/utils/`](src/utils/) - Shared utilities and helpers
### **Key Patterns to Follow**
1. **Always use [`ResponseBuilder`](src/utils/response_builder.rs)** for HTTP responses
2. **Persistent data only** - no mock data in production code
3. **CSP compliance** - external JS files only, no inline scripts
4. **Builder patterns** for complex object construction
5. **Error handling** with proper HTTP status codes (especially 402 for insufficient funds)
### **Testing Strategy**
- **Unit tests** for service layer logic
- **Integration tests** for controller endpoints
- **End-to-end tests** for critical user workflows
- **Performance tests** for catalog aggregation and search
### **Configuration Management**
- **Environment-based** configuration via [`ConfigurationBuilder`](src/config/builder.rs)
- **Feature flags** for dev/prod differences
- **Database connection** management
- **External service** integration settings
---
## 5. Success Criteria

## 🔧 Implementation Details
### 1. SessionDataBuilder - The Crown Jewel
The `SessionDataBuilder` is the most critical builder, handling all `UserPersistentData` construction:
```rust
// Location: src/models/builders.rs
impl SessionDataBuilder {
/// Create new user with email - single source of truth
pub fn new_user(email: &str) -> UserPersistentData {
UserPersistentData {
user_email: email.to_string(),
auto_topup_settings: None,
display_currency: Some("USD".to_string()),
quick_topup_amounts: Some(vec![dec!(10), dec!(25), dec!(50), dec!(100)]),
wallet_balance_usd: dec!(0),
// All other fields via Default::default()
..Default::default()
}
}
/// Load existing or create new user - handles both cases
pub fn load_or_create(email: &str) -> UserPersistentData {
UserPersistence::load_user_data(email)
.unwrap_or_else(|| Self::new_user(email))
}
}
```
### 2. Migration Success Stories
#### Before: Scattered Manual Initializations (24 compilation errors)
```rust
// ❌ OLD: Manual initialization in farmer.rs
UserPersistentData {
auto_topup_settings: None,
display_currency: Some("USD".to_string()),
quick_topup_amounts: Some(vec![dec!(10), dec!(25), dec!(50), dec!(100)]),
user_email: user_email.to_string(),
wallet_balance_usd: Decimal::ZERO,
transactions: Vec::new(),
// ... 30+ more fields manually specified
// ❌ MISSING: orders field -> compilation error
}
```
#### After: Centralized Builder Pattern (0 compilation errors)
```rust
// ✅ NEW: Single line, all fields included automatically
let mut persistent_data = SessionDataBuilder::load_or_create(user_email);
```
### 3. Complete Migration Coverage
**✅ Fully Migrated Modules:**
- **Wallet Controller**: 2 instances → `SessionDataBuilder::load_or_create()`
- **Session Manager**: 1 instance → `SessionDataBuilder::new_user()`
- **Node Rental**: 1 instance → `SessionDataBuilder::new_user()`
- **Slice Rental**: 1 instance → `SessionDataBuilder::new_user()`
- **Farmer Service**: 6+ instances → `SessionDataBuilder::load_or_create()` & `new_user()`
- **User Persistence**: 12+ instances → `SessionDataBuilder::load_or_create()`

## 🚀 Further Consolidation Opportunities
### Phase 2: Extended Builder Pattern Implementation
Based on codebase analysis, we can achieve even greater code reduction by extending the builder pattern to these areas:
#### 1. Configuration Builders
```rust
// Current: Scattered configuration in multiple files
// Opportunity: Centralized ConfigurationBuilder
pub struct ConfigurationBuilder;
impl ConfigurationBuilder {
pub fn development() -> AppConfig { /* ... */ }
pub fn production() -> AppConfig { /* ... */ }
pub fn testing() -> AppConfig { /* ... */ }
}
```
#### 2. Service Factory Pattern
```rust
// Current: Manual service instantiation
// Opportunity: ServiceFactory with builder pattern
pub struct ServiceFactory;
impl ServiceFactory {
pub fn create_order_service() -> OrderService { /* ... */ }
pub fn create_user_service() -> UserService { /* ... */ }
pub fn create_product_service() -> ProductService { /* ... */ }
}
```
#### 3. Response Builders
```rust
// Current: Manual JSON response construction
// Opportunity: ResponseBuilder for consistent API responses
pub struct ApiResponseBuilder<T>;
impl<T> ApiResponseBuilder<T> {
pub fn success(data: T) -> ApiResponse<T> { /* ... */ }
pub fn error(message: &str) -> ApiResponse<T> { /* ... */ }
pub fn paginated(data: Vec<T>, page: u32, total: u32) -> ApiResponse<Vec<T>> { /* ... */ }
}
```
#### 4. Mock Data Builders
```rust
// Current: Scattered mock data creation
// Opportunity: MockDataBuilder for testing
pub struct MockDataBuilder;
impl MockDataBuilder {
pub fn user_with_balance(email: &str, balance: Decimal) -> UserPersistentData { /* ... */ }
pub fn product_with_price(name: &str, price: Decimal) -> Product { /* ... */ }
pub fn order_with_items(user_id: &str, items: Vec<OrderItem>) -> Order { /* ... */ }
}
```

## 🔍 AI Understanding Guide
### For Future AI Assistance
When working with the Project Mycelium codebase, follow these patterns:
#### 1. UserPersistentData Creation
```rust
// ✅ ALWAYS use builder pattern
let user_data = SessionDataBuilder::load_or_create(email);
let new_user = SessionDataBuilder::new_user(email);
// ❌ NEVER use manual initialization
let user_data = UserPersistentData { /* manual fields */ };
```
#### 2. Adding New Fields
```rust
// ✅ Add to Default implementation
#[derive(Default)]
struct UserPersistentData {
// existing fields...
new_field: Option<String>, // Automatically included via ..Default::default()
}
// ✅ Update builder if needed
impl SessionDataBuilder {
pub fn new_user(email: &str) -> UserPersistentData {
UserPersistentData {
user_email: email.to_string(),
// specific defaults...
..Default::default() // Includes new_field automatically
}
}
}
```
#### 3. Service Construction
```rust
// ✅ Use existing builders where available
let currency_service = CurrencyServiceBuilder::new()
.base_currency("USD")
.cache_duration(60)
.build()?;
// ✅ Follow builder pattern for new services
let new_service = NewServiceBuilder::new()
.with_config(config)
.with_dependencies(deps)
.build()?;
```

## 🏗️ Phase 2 Implementation Roadmap
### **Priority 1: ConfigurationBuilder** (~150 line reduction)
**Current Problem:**
```rust
// ❌ Scattered configuration creation in multiple files
let config = Config::builder()
.set_default("server.host", "127.0.0.1")?
.set_default("server.port", 9999)?
.set_default("server.workers", None::<u32>)?
.set_default("templates.dir", "./src/views")?
.add_source(File::with_name("config/default").required(false))
.add_source(File::with_name("config/local").required(false))
.add_source(config::Environment::with_prefix("APP").separator("__"))
.build()?;
```
**Solution: Centralized ConfigurationBuilder**
```rust
// ✅ Single-source-of-truth configuration
pub struct ConfigurationBuilder;
impl ConfigurationBuilder {
pub fn development() -> AppConfig {
AppConfig {
server: ServerConfig {
host: "127.0.0.1".to_string(),
port: 9999,
workers: Some(4),
},
templates: TemplateConfig {
dir: "./src/views".to_string(),
},
..Default::default()
}
}
pub fn production() -> AppConfig {
AppConfig {
server: ServerConfig {
host: "0.0.0.0".to_string(),
port: 8080,
workers: Some(num_cpus::get() as u32),
},
templates: TemplateConfig {
dir: "/app/templates".to_string(),
},
..Default::default()
}
}
pub fn testing() -> AppConfig {
AppConfig {
server: ServerConfig {
host: "127.0.0.1".to_string(),
port: 0, // Random port
workers: Some(1),
},
..Default::default()
}
}
pub fn from_env() -> Result<AppConfig, ConfigError> {
match env::var("APP_ENV").unwrap_or_else(|_| "development".to_string()).as_str() {
"production" => Ok(Self::production()),
"testing" => Ok(Self::testing()),
_ => Ok(Self::development()),
}
}
}
```
**Usage Pattern:**
```rust
// ✅ Clean, readable configuration
let config = ConfigurationBuilder::from_env()?;
let dev_config = ConfigurationBuilder::development();
let prod_config = ConfigurationBuilder::production();
```
### **Priority 2: ServiceFactory** (~100 line reduction)
**Current Problem:**
```rust
// ❌ Repeated service instantiation throughout codebase
let farmer_service = match crate::services::farmer::FarmerService::builder().build() {
Ok(service) => service,
Err(e) => {
log::error!("Failed to build farmer service: {}", e);
return Ok(HttpResponse::InternalServerError().json(serde_json::json!({
"error": "Service initialization failed"
})));
}
};
```
**Solution: Centralized ServiceFactory**
```rust
// ✅ Single-source-of-truth service creation
pub struct ServiceFactory;
impl ServiceFactory {
pub fn create_farmer_service() -> Result<FarmerService, String> {
FarmerService::builder()
.auto_sync_enabled(true)
.metrics_collection(true)
.build()
}
pub fn create_order_service() -> Result<OrderService, String> {
let currency_service = Self::create_currency_service()?;
let product_service = Self::create_product_service()?;
OrderService::builder()
.currency_service(currency_service)
.product_service(product_service)
.auto_save(true)
.build()
}
pub fn create_user_service() -> Result<UserService, String> {
UserService::builder()
.include_metrics(true)
.cache_enabled(true)
.real_time_updates(true)
.build()
}
pub fn create_currency_service() -> Result<CurrencyService, String> {
CurrencyServiceBuilder::new()
.base_currency("USD")
.cache_duration(60)
.auto_update(true)
.build()
}
pub fn create_product_service() -> Result<ProductService, String> {
let currency_service = Self::create_currency_service()?;
ProductServiceBuilder::new()
.currency_service(currency_service)
.cache_enabled(true)
.include_slice_products(true)
.build()
}
// Convenience method for controllers
pub fn create_all_services() -> Result<ServiceBundle, String> {
Ok(ServiceBundle {
farmer: Self::create_farmer_service()?,
order: Self::create_order_service()?,
user: Self::create_user_service()?,
currency: Self::create_currency_service()?,
product: Self::create_product_service()?,
})
}
}
pub struct ServiceBundle {
pub farmer: FarmerService,
pub order: OrderService,
pub user: UserService,
pub currency: CurrencyService,
pub product: ProductService,
}
```
**Usage Pattern:**
```rust
// ✅ Clean, error-handled service creation
let farmer_service = ServiceFactory::create_farmer_service()
.map_err(|e| actix_web::error::ErrorInternalServerError(e))?;
// ✅ Or get all services at once
let services = ServiceFactory::create_all_services()
.map_err(|e| actix_web::error::ErrorInternalServerError(e))?;
```
### **Priority 3: ResponseBuilder** (~200 line reduction)
**Current Problem:**
```rust
// ❌ Repeated JSON response construction
Ok(HttpResponse::Ok().json(serde_json::json!({
"success": true,
"message": "Operation completed successfully",
"data": result_data
})))
Ok(HttpResponse::InternalServerError().json(serde_json::json!({
"success": false,
"error": "Service initialization failed",
"details": error_message
})))
```
**Solution: Centralized ResponseBuilder**
```rust
// ✅ Single-source-of-truth API responses
pub struct ApiResponseBuilder;
impl ApiResponseBuilder {
pub fn success<T: Serialize>(data: T) -> HttpResponse {
HttpResponse::Ok().json(serde_json::json!({
"success": true,
"data": data,
"timestamp": Utc::now().to_rfc3339()
}))
}
pub fn success_with_message<T: Serialize>(data: T, message: &str) -> HttpResponse {
HttpResponse::Ok().json(serde_json::json!({
"success": true,
"message": message,
"data": data,
"timestamp": Utc::now().to_rfc3339()
}))
}
pub fn error(message: &str) -> HttpResponse {
HttpResponse::InternalServerError().json(serde_json::json!({
"success": false,
"error": message,
"timestamp": Utc::now().to_rfc3339()
}))
}
pub fn error_with_details(message: &str, details: &str) -> HttpResponse {
HttpResponse::InternalServerError().json(serde_json::json!({
"success": false,
"error": message,
"details": details,
"timestamp": Utc::now().to_rfc3339()
}))
}
pub fn unauthorized(message: &str) -> HttpResponse {
HttpResponse::Unauthorized().json(serde_json::json!({
"success": false,
"error": message,
"code": "UNAUTHORIZED",
"timestamp": Utc::now().to_rfc3339()
}))
}
pub fn not_found(resource: &str) -> HttpResponse {
HttpResponse::NotFound().json(serde_json::json!({
"success": false,
"error": format!("{} not found", resource),
"code": "NOT_FOUND",
"timestamp": Utc::now().to_rfc3339()
}))
}
pub fn paginated<T: Serialize>(
data: Vec<T>,
page: u32,
per_page: u32,
total: u32
) -> HttpResponse {
HttpResponse::Ok().json(serde_json::json!({
"success": true,
"data": data,
"pagination": {
"page": page,
"per_page": per_page,
"total": total,
"total_pages": (total + per_page - 1) / per_page
},
"timestamp": Utc::now().to_rfc3339()
}))
}
pub fn validation_error(errors: Vec<&str>) -> HttpResponse {
HttpResponse::BadRequest().json(serde_json::json!({
"success": false,
"error": "Validation failed",
"validation_errors": errors,
"code": "VALIDATION_ERROR",
"timestamp": Utc::now().to_rfc3339()
}))
}
}
```
**Usage Pattern:**
```rust
// ✅ Clean, consistent API responses
return Ok(ApiResponseBuilder::success(farmer_data));
return Ok(ApiResponseBuilder::error("Service initialization failed"));
return Ok(ApiResponseBuilder::unauthorized("User not authenticated"));
return Ok(ApiResponseBuilder::not_found("Node"));
return Ok(ApiResponseBuilder::paginated(nodes, page, per_page, total));
```
### **Priority 4: Persistent Data Integration** (~180 line reduction + Mock Elimination)
**Current Problem:**
```rust
// ❌ Scattered mock data creation throughout codebase
let mock_products = vec![
Product { name: "Mock VM".to_string(), /* ... */ },
Product { name: "Mock Storage".to_string(), /* ... */ },
];
// ❌ Hardcoded mock services, apps, nodes
let mock_services = get_hardcoded_services();
let mock_apps = get_hardcoded_apps();
```
**Solution: Persistent Data Integration with DataAggregator**
**🏭 Industry Standard Architecture: Real Data Only**
This approach eliminates all mock data and uses only persistent user data from `user_data/` directory, which is the industry-standard production approach:
```rust
// ✅ Real data aggregation from persistent storage
pub struct DataAggregator;
impl DataAggregator {
/// Aggregate all marketplace products from real user data
pub fn get_marketplace_products() -> Vec<Product> {
let mut products = Vec::new();
// Load all user data files from user_data/ directory
if let Ok(entries) = std::fs::read_dir("user_data/") {
for entry in entries.flatten() {
if let Some(file_name) = entry.file_name().to_str() {
if file_name.ends_with(".json") && !file_name.ends_with("_cart.json") {
if let Ok(user_data) = UserPersistence::load_user_data_from_file(&entry.path()) {
// Aggregate products from user's services
products.extend(Self::services_to_products(&user_data.services));
// Aggregate products from user's apps
products.extend(Self::apps_to_products(&user_data.apps));
// Aggregate products from user's slice products
products.extend(Self::slice_products_to_products(&user_data.slice_products));
// Aggregate products from user's nodes (for rental)
products.extend(Self::nodes_to_products(&user_data.nodes));
}
}
}
}
}

let marketplace_services = DataAggregator::get_marketplace_services();
let marketplace_apps = DataAggregator::get_marketplace_apps();
let marketplace_nodes = DataAggregator::get_marketplace_nodes();
let marketplace_stats = DataAggregator::get_marketplace_stats();
```
**🏭 Industry Standard Benefits:**
- **Real Data Only**: No mock data, all products/services come from actual users in `user_data/`
- **Dynamic Marketplace**: Marketplace content grows organically as users add services, apps, nodes
- **Authentic Experience**: Users see real offerings from real providers
- **Production Ready**: No mock-to-real data migration needed
- **Scalable Architecture**: Handles any number of users and their offerings
- **Data Integrity**: All marketplace data backed by persistent user storage
### **Priority 5: ErrorBuilder** (~120 line reduction)
**Solution: Centralized Error Handling**
```rust
pub struct ErrorBuilder;
impl ErrorBuilder {
pub fn service_error(service: &str, operation: &str, details: &str) -> String {
format!("Failed to {} in {}: {}", operation, service, details)
}
pub fn validation_error(field: &str, reason: &str) -> String {
format!("Validation failed for {}: {}", field, reason)
}
pub fn authentication_error(reason: &str) -> String {
format!("Authentication failed: {}", reason)
}
pub fn not_found_error(resource: &str, id: &str) -> String {
format!("{} with ID '{}' not found", resource, id)
}
}
```
### **Priority 6: ContextBuilder Enhancement** (~80 line reduction)
**Solution: Enhanced Template Context Building**
```rust
pub struct ContextBuilder {
context: tera::Context,
}
impl ContextBuilder {
pub fn new() -> Self {
Self {
context: tera::Context::new(),
}
}
pub fn with_user(mut self, user: &User) -> Self {
self.context.insert("user", user);
self
}
pub fn with_dashboard_data(mut self, section: &str) -> Self {
self.context.insert("active_page", "dashboard");
self.context.insert("active_section", section);
self
}
pub fn with_marketplace_data(mut self, products: &[Product]) -> Self {
self.context.insert("products", products);
self.context.insert("active_page", "marketplace");
self
}
pub fn build(self) -> tera::Context {
self.context
}
}
```

- **Response Consistency**: 100% API endpoints using ResponseBuilder
### **Qualitative Goals**:
- **Maintainability**: Single source of truth for all patterns
- **Scalability**: Industry-standard architecture patterns
- **Developer Experience**: Clear, consistent patterns for future development
- **Production Readiness**: No mock data, all persistent data usage
---
## **Migration Methodology**
### **Proven Approach** (Based on successful ServiceFactory migration):
1. **Systematic Manual Approach**: Line-by-line fixes more effective than scripts
2. **Compilation-Driven Development**: Use compiler errors to guide fixes
3. **Incremental Testing**: Verify compilation after each major change
4. **Documentation First**: Document patterns before implementing
5. **Clean Up**: Remove unused imports and dead code
### **Avoid**:
- **Over-reliance on Scripts**: Manual refinement always required
- **Bulk Changes**: Can cause compilation cascades

# Log-Free Codebase Policy
## Overview
The Project Mycelium maintains a **log-free codebase** in main and development branches as a core architectural design decision. This policy ensures clean, production-ready code and simplifies maintenance, debugging, and AI-assisted development.
## Policy Statement
**All `log::` statements must be removed from the codebase before merging to main or development branches.**
## Rationale
### 1. **Code Cleanliness**
- Removes visual clutter and noise from the codebase
- Improves code readability and maintainability
- Reduces file size and complexity
### 2. **Production Readiness**
- Eliminates potential performance overhead from logging statements
- Prevents accidental logging of sensitive information
- Ensures consistent behavior across environments
### 3. **AI-Assisted Development**
- Simplifies code analysis and pattern recognition for AI tools
- Reduces token count and complexity for AI code generation
- Enables more accurate code migrations and refactoring
### 4. **Maintenance Benefits**
- Reduces merge conflicts from logging changes
- Eliminates outdated or inconsistent log messages
- Simplifies code review process
## Implementation Guidelines
### ✅ **Allowed Usage**
- **Feature Branches**: Developers may use `log::` statements for troubleshooting and debugging in feature branches
- **Local Development**: Temporary logging for development and testing purposes
- **Debugging Sessions**: Short-term logging to diagnose specific issues
### ❌ **Prohibited Usage**
- **Main Branch**: No `log::` statements allowed in main branch
- **Development Branch**: No `log::` statements allowed in development branch
- **Production Code**: No logging statements in production-ready code
- **Permanent Logging**: No long-term or permanent logging infrastructure
## Enforcement
### 1. **Pre-Merge Cleanup**
All feature branches must have `log::` statements removed before creating pull requests:
```bash
# Check for log statements before merging
find src -name "*.rs" -exec grep -l "log::" {} \;
# Remove all log statements (if any found)
find src -name "*.rs" -exec perl -i -pe 'BEGIN{undef $/;} s/\s*log::[^;]*;//g' {} \;
# Verify removal
cargo check --lib
```
### 2. **Automated Checks**
- CI/CD pipeline should include log statement detection
- Pre-commit hooks can prevent accidental commits with logging
- Code review checklist includes log statement verification
### 3. **Migration History**
- **2025-01-06**: Removed 881+ log statements from entire codebase
- **Dashboard Controller**: 443 log statements removed
- **Other Controllers**: 438 log statements removed across 24 files
## Alternative Approaches
### For Debugging
Instead of permanent logging, use:
1. **Conditional Compilation**:
```rust
#[cfg(debug_assertions)]
eprintln!("Debug: {}", value);
```
2. **Feature Flags**:
```rust
#[cfg(feature = "debug-logging")]
log::debug!("Debug information");
```
3. **Test-Only Logging**:
```rust
#[cfg(test)]
println!("Test debug: {}", value);
```
### For Production Monitoring
- Use external monitoring tools (Prometheus, Grafana)
- Implement structured error handling with Result types
- Use application metrics instead of log statements
- Implement health check endpoints
## Benefits Realized
### 1. **Codebase Statistics**
- **Before**: 881+ log statements across 24 files
- **After**: 0 log statements (100% reduction)
- **Compilation**: Clean builds with only minor unused variable warnings
### 2. **Development Improvements**
- Simplified ResponseBuilder migration process
- Reduced code complexity for AI-assisted refactoring
- Cleaner code reviews and merge processes
- Improved code readability and maintainability
### 3. **Performance Benefits**
- Reduced binary size
- Eliminated runtime logging overhead
- Faster compilation times
- Cleaner production deployments
## Compliance
### Developer Responsibilities
1. **Remove all `log::` statements** before creating pull requests
2. **Verify clean builds** after log removal
3. **Use alternative debugging approaches** for troubleshooting
4. **Follow the log-free policy** consistently across all contributions
### Code Review Requirements
1. **Check for log statements** in all code reviews
2. **Verify compilation** after any log-related changes
3. **Ensure policy compliance** before approving merges
4. **Document any exceptions** (if absolutely necessary)
## Exceptions
**No exceptions are currently allowed.** The log-free policy is absolute for main and development branches.
If logging becomes absolutely necessary for specific use cases, it must be:
1. Approved by the architecture team
2. Implemented with feature flags
3. Documented as an architectural decision
4. Reviewed regularly for removal

# Project Mycelium - Supabase Architecture & Deployment Roadmap 2025
## 🎯 Executive Summary
Complete transformation of Project Mycelium from hybrid TFP/USD system with JSON storage to production-ready, highly available platform using industry-standard open source technologies.
**Key Decisions:**
- **Database**: Self-hosted Supabase (PostgreSQL + PostgREST + Auth + Real-time)
- **Currency**: Pure USD credits system (eliminate TFP conversion)
- **Deployment**: Progressive scaling from single VM to HA k3s cluster
- **Infrastructure**: ThreeFold Grid with multi-cloud portability
---
## 📊 Current Status Assessment
### Issues Identified:
- ❌ **TFP → Credits Refactor**: PARTIALLY COMPLETE - hybrid logic remains
- ❌ **Database**: JSON file storage not scalable for production
- ❌ **Single Point of Failure**: Current deployment lacks redundancy
- ❌ **Complex Conversion**: TFP/USD conversion scattered throughout codebase
### Evidence from Codebase:
```rust
// Current problematic hybrid approach:
mock_data.wallet_balance_usd -= rental_cost; // Some USD usage
// But TFP references remain in pools.html:
// "Buy ThreeFold Points (TFP) with TFT"
```
---
## 🏗️ Target Architecture
### Supabase Self-Hosted Stack:
- **PostgreSQL**: Core database with ACID compliance
- **PostgREST**: Auto-generated REST API from database schema
- **GoTrue**: JWT-based authentication service
- **Realtime**: WebSocket subscriptions for live updates
- **Studio**: Web-based database management
### Why Supabase Self-Hosted:
- ✅ **100% Open Source**: All components under permissive licenses
- ✅ **Zero Vendor Lock-in**: Deploy anywhere, migrate anytime
- ✅ **Cost Effective**: No managed service fees
- ✅ **ThreeFold Aligned**: Decentralized infrastructure
---

---
## 🔧 Technical Implementation
### Rust Backend Integration:
```rust
use supabase_rs::{Supabase, SupabaseClient};
pub struct MarketplaceDB {
client: SupabaseClient,
}
impl MarketplaceDB {
pub async fn get_user_balance(&self, user_id: i32) -> Result<Decimal, Error> {
let response = self.client
.from("users")
.select("wallet_balance_usd")
.eq("id", user_id.to_string())
.execute()
.await?;
Ok(response.parse()?)
}
pub async fn update_balance(&self, user_id: i32, amount: Decimal) -> Result<(), Error> {
self.client
.from("users")
.update(json!({"wallet_balance_usd": amount}))
.eq("id", user_id.to_string())
.execute()
.await?;
Ok(())
}
}
```
### Controller Updates:
```rust
// Pure USD operations - no TFP conversion
pub async fn buy_credits(form: web::Json<BuyCreditsRequest>) -> Result<HttpResponse, Error> {
let db = MarketplaceDB::new();
let amount_usd = form.amount; // Direct USD, no conversion
let current_balance = db.get_user_balance(user_id).await?;
let new_balance = current_balance + amount_usd;
db.update_balance(user_id, new_balance).await?;
Ok(HttpResponse::Ok().json(json!({
"success": true,
"new_balance": new_balance
})))
}
```
---
## 📋 Migration Procedures
### Data Migration Strategy:
```rust
pub async fn migrate_all_user_data() -> Result<(), Error> {
let db = MarketplaceDB::new();
for entry in glob("./user_data/*.json")? {
let user_data: Value = serde_json::from_str(&fs::read_to_string(entry?)?)?;
// Extract and migrate user data
let email = user_data["email"].as_str().unwrap();
let balance = user_data["wallet_balance_usd"].as_f64().unwrap_or(0.0);
db.create_user(email, balance.into()).await?;
}
Ok(())
}
```
### Validation:
```rust
pub async fn validate_migration() -> Result<bool, Error> {
let db = MarketplaceDB::new();
let user_count = db.count_users().await?;
let total_balance = db.sum_all_balances().await?;
let json_stats = analyze_json_files().await?;
Ok(user_count == json_stats.user_count &&
(total_balance - json_stats.total_balance).abs() < Decimal::new(1, 2))
}
```
---
## 🔒 Security Implementation
### Row Level Security:
```sql
ALTER TABLE users ENABLE ROW LEVEL SECURITY;
CREATE POLICY "Users view own data" ON users
FOR SELECT USING (auth.uid()::text = uuid::text);
```
### JWT Validation:
```rust
pub async fn validate_jwt(req: ServiceRequest) -> Result<ServiceResponse, Error> {
let token = extract_bearer_token(&req)?;
let claims = decode::<Claims>(token, &DecodingKey::from_secret(JWT_SECRET.as_bytes()))?;
req.extensions_mut().insert(claims);
Ok(next.call(req).await?)
}
```
---
## 📊 Monitoring & Backup
### Health Checks:

---
## Refactoring Decisions
### TFP → TFC Refactor Details
#### **Naming Conventions**
- **Old**: TFP, ThreeFold Points, tfp_amount, buyTFP()
- **New**: TFC, ThreeFold Credits, tfc_amount, buyCredits()
#### **Code Changes Required**
| Component | Changes | Files Affected |
|-----------|---------|----------------|
| **Rust Backend** | Remove conversion logic, update structs | `models/`, `controllers/`, `services/` |
| **Frontend HTML** | Update all UI text and form labels | `views/dashboard/` |
| **JavaScript** | Rename functions and variables | `*.html` inline JS |
| **Database Schema** | Migrate currency fields | Migration scripts |
| **API Endpoints** | Update request/response formats | `routes/mod.rs` |
#### **Configuration System**
```rust
// New configurable credit system
pub struct MarketplaceConfig {
pub tfc_to_usd_rate: Decimal, // Default: 1.0
pub credit_currency_code: String, // "TFC"
pub credit_display_name: String, // "ThreeFold Credits"
pub credit_symbol: String, // "TFC"
}
```
---
## Technical Debt Resolution
### Resolved Issues
1. **Hybrid Currency Complexity** → Single TFC system
2. **File-based Storage** → PostgreSQL database
3. **Manual Scaling** → Container orchestration ready
### Remaining Technical Debt
- [ ] Legacy API endpoints (maintain backward compatibility)
- [ ] Old configuration format migration
- [ ] Performance optimization for high-traffic scenarios
---
## Future Considerations
### Potential Enhancements
1. **Multi-Currency Support**: If needed, add other currencies while keeping TFC as base
2. **Credit Packages**: Bulk credit purchase discounts
3. **Credit Expiration**: Optional expiry dates for credits
4. **Credit Transfers**: Peer-to-peer credit transfers
5. **Credit Analytics**: Usage tracking and reporting
### Scalability Roadmap
1. **Phase 1**: Single-node production (current)
2. **Phase 2**: Multi-node k3s cluster
3. **Phase 3**: Multi-region deployment
4. **Phase 4**: Global CDN and edge computing
### Monitoring & Observability
- Application metrics via Prometheus
- Log aggregation via Loki
- Distributed tracing via Jaeger
- Health checks and alerting
---
## DevOps Guidelines
### For Future Maintainers
#### **Understanding the Credit System**
- **TFC = ThreeFold Credits**: The single currency used throughout
- **1 TFC = 1 USD by default**: Configurable via `marketplace.config`
- **No Conversions**: All calculations use TFC directly
#### **Configuration Management**
```bash
# Adjust credit value
export TFC_USD_RATE=1.0 # 1 TFC = 1 USD
# Update via config file
echo "tfc_to_usd_rate = 1.0" >> marketplace.config
```
#### **Database Schema**
- All currency fields store TFC amounts
- No exchange rate tables needed
- Simple decimal precision for credits
#### **Deployment Notes**
- Use provided Docker Compose for development
- Follow k3s automation for production HA
- Monitor credit balance calculations in logs
---
## Conclusion
The TFP → TFC refactor represents a strategic shift toward:
- **Simplicity**: Single currency system
- **Flexibility**: Configurable credit values
- **Maintainability**: Clean, documented codebase
- **Scalability**: Modern database and orchestration
This decision trail ensures future teams understand the rationale and can continue evolving the marketplace architecture effectively.
---
**Next Steps**: Execute TFP → TFC refactor implementation as documented in the architecture plan.

# Dual UX Specification: Modern App + E-commerce Flows
**Document Purpose**: Comprehensive UX specification supporting both modern app-style instant purchase and traditional e-commerce cart workflows.
**Last Updated**: 2025-08-04
**Status**: Implementation Ready
---
## Overview
The Project Mycelium supports **two distinct user experience patterns** to accommodate different user preferences and use cases:
1. **Modern App Flow** (OpenRouter-style): Instant purchase with wallet top-up
2. **Traditional E-commerce Flow**: Cart-based shopping with checkout
---
## UX Flow Comparison
### **Flow 1: Modern App Style (OpenRouter-inspired)**
```mermaid
graph TD
A[Browse Marketplace] --> B[Register/Login]
B --> C[View Service]
C --> D[Buy Now Button]
D --> E{TFC Balance Check}
E -->|Sufficient| F[Instant Deploy]
E -->|Insufficient| G[Auto Top-up Modal]
G --> H[Stripe Payment]
H --> I[TFC Added]
I --> F
F --> J[Deployment Status]
J --> K[Service Active]
```
**Key Features:**
- **Instant Purchase**: Single-click buying
- **Auto Top-up**: Seamless balance management
- **Wallet-centric**: Balance always visible
- **Minimal Friction**: No cart, no checkout process
### **Flow 2: Traditional E-commerce Style**
```mermaid
graph TD
A[Browse Marketplace] --> B[View Service]
B --> C[Add to Cart]
C --> D[Continue Shopping]
D --> E[Review Cart]
E --> F[Checkout]
F --> G{Payment Method}
G -->|TFC Balance| H[Pay with TFC]
G -->|Credit Card| I[Stripe Checkout]
I --> J[TFC Purchase]
J --> H
H --> K[Batch Deployment]
K --> L[Order Confirmation]
```
**Key Features:**
- **Bulk Shopping**: Multiple items in cart
- **Price Comparison**: Review before purchase
- **Batch Deployment**: Deploy multiple services together
- **Familiar UX**: Traditional e-commerce experience

## Complete UX/UI Flow Analysis
### **User Journey: From Discovery to Deployment**
```mermaid
graph TD
A[User Browses Marketplace] --> B[Selects App/VM/Service]
B --> C[Add to Cart]
C --> D[Review Cart]
D --> E{Payment Method}
E -->|Has TFC Credits| F[Pay with TFC]
E -->|Needs Credits| G[Buy TFC with Stripe]

J --> K[Deployment Queue]
K --> L[TFC → TFT Conversion]
L --> M[ThreeFold Grid Deployment]
M --> N[Service Active]
N --> O[User Dashboard Access]
```
### **Critical UX/UI Components**
#### **1. Shopping Cart & Checkout**
- **Add to Cart**: ✅ Working
- **Buy Now**: ❌ **MISSING** - Direct purchase flow
- **Cart Review**: Price breakdown, TFC cost, estimated deployment time
- **Payment Options**: TFC balance vs. Stripe top-up
#### **2. TFC Balance Management**
- **Real-time Balance**: Display current TFC credits
- **Deduction Logic**: `1000 TFC - 50 TFC product = 950 TFC`
- **Low Balance Alerts**: Prompt for Stripe top-up
- **Transaction History**: All TFC purchases and usage
#### **3. Payment Integration**
- **Stripe Integration**: Credit card payments → TFC credits
- **Currency Bridge**: USD → TFC (1:1) → TFT (market rate)
- **Commission Handling**: Marketplace cut before grid deployment
#### **4. Deployment Status**
- **Queue Position**: Real-time deployment progress
- **Grid Status**: ThreeFold node selection and deployment
- **Service Access**: Connection details and management
---
## Payment System Integration
### **Stripe Payment Flow**
```rust
// Proposed Stripe Integration Architecture
pub struct StripePaymentService {
stripe_client: stripe::Client,
webhook_secret: String,
}
impl StripePaymentService {
pub async fn create_payment_intent(
&self,
amount_usd: Decimal,
user_id: String,
) -> Result<PaymentIntent> {
// Create Stripe payment intent
// Amount in cents (USD)
let amount_cents = (amount_usd * 100).to_u64().unwrap();
stripe::PaymentIntent::create(&self.stripe_client, CreatePaymentIntent {
amount: amount_cents,
currency: Currency::USD,
metadata: [("user_id", user_id)].iter().cloned().collect(),
..Default::default()
}).await
}
pub async fn handle_webhook(&self, payload: &str, signature: &str) -> Result<()> {
// Verify webhook signature
// Process payment success
// Add TFC credits to user balance
// Trigger any pending deployments
}
}
```
### **TFC ↔ Fiat Bridge Logic**
| User Action | USD Amount | TFC Credits | Marketplace Cut | Grid Deployment |
|-------------|------------|-------------|-----------------|-----------------|
| Buy 100 TFC | $100.00 | +100 TFC | $0 (top-up) | N/A |
| Deploy VM (50 TFC) | N/A | -50 TFC | $5 (10%) | $45 → TFT |
| Deploy App (25 TFC) | N/A | -25 TFC | $2.50 (10%) | $22.50 → TFT |
### **Commission Structure**
- **Marketplace Fee**: 10% of each deployment
- **Grid Payment**: 90% converted to TFT for actual deployment
- **Revenue Split**: Transparent fee structure for users
---
## ThreeFold Grid Deployment Automation
### **Deployment Pipeline Architecture**
```mermaid
graph TD
A[User Purchases Service] --> B[TFC Deducted]
B --> C[Deployment Queue]
C --> D[Commission Calculation]
D --> E[Remaining Amount → TFT]
E --> F[ThreeFold Grid API]

G --> H[Resource Allocation]
H --> I[Service Deployment]
I --> J[Connection Details]
J --> K[User Notification]
```
### **Grid Integration Service**
```rust
pub struct ThreeFoldGridService {
grid_client: TFGridClient,
tft_wallet: TFTWallet,
}
impl ThreeFoldGridService {
pub async fn deploy_vm(
&self,
deployment_spec: VMDeploymentSpec,
tfc_amount: Decimal,
marketplace_cut: Decimal,
) -> Result<DeploymentResult> {
// Calculate actual deployment cost
let deployment_amount = tfc_amount - marketplace_cut;
// Convert TFC to TFT at current market rate
let tft_amount = self.convert_usd_to_tft(deployment_amount).await?;
// Deploy on ThreeFold Grid
let deployment = self.grid_client.deploy_vm(VMDeployment {
cpu: deployment_spec.cpu,
memory: deployment_spec.memory,
storage: deployment_spec.storage,
payment: tft_amount,
..Default::default()
}).await?;
Ok(DeploymentResult {
deployment_id: deployment.id,
grid_node: deployment.node_id,
access_details: deployment.connection_info,
tft_spent: tft_amount,
})
}
async fn convert_usd_to_tft(&self, usd_amount: Decimal) -> Result<Decimal> {
// Get current TFT/USD rate from ThreeFold Grid
let rate = self.grid_client.get_tft_usd_rate().await?;
Ok(usd_amount / rate)
}
}
```
### **Deployment Types & Automation**
| Service Type | TFC Cost | Deployment Method | Grid Resource |
|--------------|----------|-------------------|---------------|
| **VM Instance** | 50-200 TFC | Automated VM deployment | Compute nodes |
| **Kubernetes Cluster** | 100-500 TFC | k3s cluster provisioning | Multiple nodes |
| **Storage Service** | 25-100 TFC | Distributed storage | Storage nodes |
| **Application** | 10-50 TFC | Container deployment | App-specific nodes |
---
## Revenue Model & Commission Structure
### **Marketplace Economics**
```
User Payment Flow:
┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐
│ User Pays │ │ Marketplace │ │ ThreeFold Grid │
│ $100 USD │───▶│ Takes 10% │───▶│ Receives 90% │
│ via Stripe │ │ ($10 USD) │ │ ($90 → TFT) │
└─────────────────┘ └─────────────────┘ └─────────────────┘
```
### **Commission Breakdown**
- **Platform Fee**: 10% of each deployment
- **Payment Processing**: 2.9% + $0.30 (Stripe fees)
- **Net Marketplace Revenue**: ~7% per transaction
- **Grid Deployment**: 90% converted to TFT for actual resources
### **Revenue Projections**
| Monthly Deployments | Avg. Deployment | Gross Revenue | Net Revenue |
|---------------------|-----------------|---------------|-------------|
| 1,000 | $75 | $7,500 | $5,250 |
| 5,000 | $75 | $37,500 | $26,250 |
| 10,000 | $75 | $75,000 | $52,500 |

## Critical Questions & Analysis
### **Is This a Complete UX/UI for the Marketplace?**
**Current State Analysis**:
✅ **Strengths**:
- Clean TFC credits system (1 TFC = 1 USD)
- Add to cart functionality working
- Clear pricing and service catalog
- User authentication and dashboard
❌ **Missing Critical Components**:
- **Buy Now button** - Direct purchase flow
- **Real-time TFC deduction** - Balance updates on purchase
- **Stripe payment integration** - Fiat → TFC conversion
- **Grid deployment automation** - TFC → TFT → Deployment
- **Deployment status tracking** - Real-time progress
- **Service management** - Post-deployment controls
### **Recommended UX/UI Enhancements**
1. **Immediate Purchase Flow**
```
[Service Page] → [Buy Now] → [Payment Method] → [Stripe/TFC] → [Deployment]
```
2. **Balance Management**
```
TFC Balance: 1000 → Purchase 50 TFC service → New Balance: 950
```
3. **Payment Options**
```
┌─ Pay with TFC Credits (if sufficient balance)
└─ Buy TFC with Credit Card (Stripe integration)
```
4. **Deployment Pipeline**
```
Payment → Queue → TFC→TFT → Grid API → Service Active → User Access
```
---
## Conclusion
The proposed marketplace architecture creates a **seamless Web2-to-Web3 bridge** that:
- **Simplifies User Experience**: Familiar credit card payments
- **Maintains Decentralization**: ThreeFold Grid deployment
- **Generates Revenue**: 10% marketplace commission
- **Scales Efficiently**: Cloud-native architecture
- **Ensures Reliability**: HA k3s deployment ready
The next implementation phase will transform this from a catalog into a **complete e-commerce platform** with automated deployment capabilities.
---
**Next Steps**: Begin Phase 2A implementation with Stripe integration and TFC purchase flow.

# ServiceFactory Architecture Documentation
## Overview
The ServiceFactory is a centralized service instantiation system that implements the single source of truth pattern for service creation throughout the Project Mycelium codebase. This architecture eliminates scattered service instantiations and provides consistent, persistent data-backed services.
## Architecture Principles
### 1. Single Source of Truth
- All service instantiations go through the ServiceFactory
- Eliminates duplicate service creation logic
- Ensures consistent service configuration across the application
### 2. Persistent Data Focus
- **No Mock Data**: All services use real persistent data from `user_data/` directory
- **Industry Standard**: Aligns with production-ready architecture patterns
- **Authentic Experience**: Users interact with real data, not mock data
### 3. Singleton Pattern Implementation
- Uses `std::sync::OnceLock` for thread-safe singleton instances
- Lazy initialization ensures services are created only when needed
- Memory efficient with shared service instances
## ServiceFactory Implementation
### Core Structure
```rust
use std::sync::{Arc, OnceLock};
use crate::services::{
currency::CurrencyService,
user_persistence::UserPersistence,
};
/// Service factory for single source of truth service instantiation
pub struct ServiceFactory;
impl ServiceFactory {
/// Creates a new CurrencyService instance using persistent data
pub fn currency_service() -> Arc<CurrencyService> {
static CURRENCY_SERVICE: OnceLock<Arc<CurrencyService>> = OnceLock::new();
CURRENCY_SERVICE.get_or_init(|| {
Arc::new(CurrencyService::builder().build().unwrap())
}).clone()
}
/// Provides access to UserPersistence for persistent data operations
pub fn user_persistence() -> Arc<UserPersistence> {
static USER_PERSISTENCE: OnceLock<Arc<UserPersistence>> = OnceLock::new();
USER_PERSISTENCE.get_or_init(|| {
Arc::new(UserPersistence::new())
}).clone()
}
}
```
### Key Features
1. **Thread-Safe Singletons**: Uses `OnceLock` for safe concurrent access
2. **Lazy Initialization**: Services created only when first accessed
3. **Arc Wrapping**: Enables efficient sharing across threads
4. **Builder Pattern Integration**: Leverages existing service builders
## Migration Results
### Quantitative Improvements
- **Files Migrated**: 7 files consolidated to use ServiceFactory
- **Code Reduction**: ~100+ lines of duplicate service instantiation code eliminated
- **Compilation Errors**: Reduced from 43 to 0 during migration
- **Mock Data Elimination**: 100% removal of MockDataService usage
### Files Successfully Migrated
1. `src/controllers/order.rs` - Order processing service instantiation
2. `src/controllers/product.rs` - Product management service instantiation
3. `src/controllers/currency.rs` - Currency conversion service instantiation
4. `src/controllers/marketplace.rs` - Marketplace service instantiation
5. `src/services/instant_purchase.rs` - Purchase service instantiation
6. `src/services/factory.rs` - ServiceFactory implementation
7. `src/services/navbar.rs` - Navigation service instantiation
### Before vs After Comparison
#### Before (Scattered Instantiation)
```rust
// In multiple files throughout codebase
let currency_service = CurrencyService::builder()
.build()
.unwrap();
```
#### After (Centralized ServiceFactory)
```rust
// Single line in any file
let currency_service = ServiceFactory::currency_service();
```
## Mock Data Elimination
### Complete Removal Strategy
The ServiceFactory migration included a comprehensive elimination of all mock data usage:
#### MockDataService Removal
- **Struct Field Removal**: Removed `mock_data: MockDataService` from CurrencyService
- **Method Updates**: Replaced all `self.mock_data.*` calls with persistent data logic
- **Import Cleanup**: Removed unused MockDataService imports
#### Persistent Data Replacement
- **Currency Data**: Replaced mock currencies with standard USD, EUR, TFT currencies
- **Exchange Rates**: Implemented real exchange rate logic instead of mock volatility
- **Configuration**: Hardcoded sensible defaults instead of mock configuration
### Currency Service Modernization
#### Standard Currency Implementation
```rust
pub fn get_supported_currencies(&self) -> Vec<Currency> {
vec![
Currency {
code: "USD".to_string(),
name: "US Dollar".to_string(),
symbol: "$".to_string(),
currency_type: CurrencyType::Fiat,
exchange_rate_to_base: dec!(1.0),
is_base_currency: true,
decimal_places: 2,
is_active: true,
provider_config: None,
last_updated: chrono::Utc::now(),
},
// EUR and TFT currencies...
]
}
```
## Migration Methodology
### Systematic Manual Approach
The migration was completed using a systematic, manual approach that proved more effective than automated scripts:
#### 1. Identification Phase
- Used `grep_search` to find all scattered service instantiations
- Catalogued `CurrencyService::builder()` and `MockDataService::new()` usage
- Identified 27+ CurrencyService instantiations and 3 MockDataService usages
#### 2. Implementation Phase
- Created ServiceFactory with singleton pattern
- Implemented thread-safe service access methods
- Added proper error handling and initialization
#### 3. Migration Phase
- **Script-Based Initial Migration**: Created Python scripts for bulk replacements
- **Manual Refinement**: Line-by-line fixes for complex cases
- **Compilation-Driven**: Used compiler errors to guide systematic fixes
#### 4. Validation Phase
- **Compilation Testing**: Ensured zero compilation errors
- **Type Safety**: Fixed all type mismatches and borrowing issues
- **Import Cleanup**: Removed unused imports and dependencies
### Lessons Learned
#### Manual vs Automated Approach
- **Scripts Useful For**: Bulk pattern replacements and initial migration
- **Manual Required For**: Complex logic changes, type fixes, and edge cases
- **Hybrid Approach**: Best results from script-assisted initial migration followed by manual refinement
#### Compilation-Driven Development
- **Error Reduction**: Systematic approach reduced errors from 43 to 0
- **Focused Fixes**: Each compilation cycle provided clear next steps
- **Quality Assurance**: Compiler ensured type safety and correctness
## Usage Guidelines
### For Developers
#### Service Access Pattern
```rust
use crate::services::ServiceFactory;
// Get currency service instance
let currency_service = ServiceFactory::currency_service();
// Use service methods
let supported_currencies = currency_service.get_supported_currencies();
```
#### Adding New Services
1. Implement service with builder pattern
2. Add singleton method to ServiceFactory
3. Update documentation and usage examples
4. Migrate existing instantiations to use ServiceFactory
### For AI Assistants
#### ServiceFactory Usage Rules
1. **Always use ServiceFactory**: Never instantiate services directly
2. **No Mock Data**: Only use persistent data from `user_data/` directory
3. **Follow Patterns**: Use established singleton patterns for new services
4. **Document Changes**: Update this documentation when adding services
#### Migration Best Practices
1. **Systematic Approach**: Use compilation errors to guide fixes
2. **Manual Refinement**: Don't rely solely on automated scripts
3. **Test Incrementally**: Verify compilation after each major change
4. **Clean Up**: Remove unused imports and dead code
## Future Enhancements
### Planned Improvements
1. **Service Discovery**: Automatic service registration and discovery
2. **Configuration Management**: Centralized service configuration
3. **Health Monitoring**: Service health checks and monitoring
4. **Dependency Injection**: Full dependency injection container
### Integration Opportunities
1. **ConfigurationBuilder**: Integrate with centralized configuration
2. **ResponseBuilder**: Coordinate with API response patterns
3. **SessionDataBuilder**: Align with user data management
4. **Error Handling**: Standardized error handling across services
## Conclusion
The ServiceFactory architecture successfully consolidates service instantiation throughout the Project Mycelium, eliminating mock data usage and establishing industry-standard patterns. This foundation enables scalable, maintainable service management and sets the stage for further architectural improvements.
The migration demonstrates the effectiveness of systematic, compilation-driven development combined with manual refinement for complex architectural changes. This approach should be used as a template for future consolidation efforts.

# Current Personas and Fixture-backed Marketplace State
Last Updated: 2025-08-09
This document captures the canonical demo/test state of the Project Mycelium when running with fixtures.
It enables developers and reviewers to reproduce the exact marketplace state and verify the intended UX.
- Data Source: fixtures (filesystem)
- How to run:
- APP_DATA_SOURCE=fixtures
- APP_FIXTURES_PATH=./user_data
- APP_DEMO_MODE=true (optional banner and safe guards)
- APP_ENABLE_MOCKS=false (we do not rely on MockDataService)
## Snapshot
- Users: 10 (user1..user10)
- Providers: user1..user3
- Mixed (provider+buyer): user4..user6
- Buyers: user7..user10
- Products: 3 (seeded; will expand)
- WireGuard VPN (category: applications) — provider: user1@example.com — featured
- Public Gateway Bundle (category: gateways) — provider: user2@example.com
- Object Storage (100GB) (category: applications) — provider: user3@example.com
- Services: TBD
- Orders: TBD
## Personas (credentials for demo)
These credentials are for demo/test environments only. Do not ship to production.
| Persona | Email | Password | Roles |
|---------|---------------------|----------|---------------------|
| user1 | user1@example.com | password | ["provider"] |
| user2 | user2@example.com | password | ["provider"] |
| user3 | user3@example.com | password | ["provider"] |
| user4 | user4@example.com | password | ["provider","buyer"] |
| user5 | user5@example.com | password | ["provider","buyer"] |
| user6 | user6@example.com | password | ["provider","buyer"] |
| user7 | user7@example.com | password | ["buyer"] |
| user8 | user8@example.com | password | ["buyer"] |
| user9 | user9@example.com | password | ["buyer"] |
| user10 | user10@example.com | password | ["buyer"] |
## Ownership and Data Rules
- No orphan data: every product/service has an owner_user_id.
- Orders link buyer_user_id -> items -> product_id/service_id.
- Future payments will be linked via payment records.
## Known Scenarios to Verify
- Buyer journey (add to cart, buy-now, view invoice).
- Provider publishing a product/service and seeing it live.
- Insufficient balance UX contract where applicable.
## Reset and Updates
- Reset to seed (planned): cargo run -- seed --reset
- Fixtures path: ./user_data
- Versioning: see ./user_data/version.json
## Change Log
- 2025-08-09: Initial scaffold with 10 demo users, pending product/service/order seeds.

# Manual Test Checklist — Fixtures Mode
Last Updated: 2025-08-10
This checklist validates the Project Mycelium when running with fixture data in `user_data/`.
## Prereqs
- APP_DATA_SOURCE=fixtures
- APP_FIXTURES_PATH=./user_data
- APP_ENABLE_MOCKS=0
- APP_CATALOG_CACHE=true
- APP_CATALOG_CACHE_TTL_SECS=5
- Optional: APP_DEMO_MODE=true
- Command: `make fixtures-run` (or `make fixtures-check` to compile only)
## Personas
- Users: `user1@example.com` … `user10@example.com`
- Password: `password`
- Roles: see `docs/dev/design/current/ux/current_personas.md`
## Sanity: Products and Categories
- [ ] Home/Marketplace page loads without error.
- [ ] Exactly 3 seeded products are visible:
- WireGuard VPN (applications) — featured
- Public Gateway Bundle (gateways)
- Object Storage (100GB) (applications)
- [ ] Categories auto-derived include `applications` and `gateways`.
- [ ] Featured section shows WireGuard VPN.
- [ ] Product detail page renders for each seeded product (name, description, price, provider).
## Dev Cache Behavior (Phase 0)
- [ ] With `APP_CATALOG_CACHE=true` and `APP_CATALOG_CACHE_TTL_SECS=5`, refresh the marketplace twice within 5s; second load should be faster locally and show identical results.
- [ ] Edit a product field in `user_data/products.json` temporarily; refresh before TTL → old value; after TTL (or restart) → new value. Revert the edit after the check.
- [ ] No duplicate products appear across sections due to catalog deduplication.
- [ ] Category pages reflect normalized singular IDs (e.g., `applications` → `application`).
## Search and Filters
- [ ] Search "vpn" returns WireGuard VPN.
- [ ] Search "storage" returns Object Storage (100GB).
- [ ] Filter by category `applications` shows 2 products; `gateways` shows 1 product.
## Cart Flow (user7@example.com - buyer)
- [ ] Login as user7 → navigate back to marketplace.
- [ ] Add WireGuard VPN to cart.
- [ ] Cart badge updates immediately (global `emitCartUpdated` behavior) and persists on refresh.
- [ ] Proceed to cart → item, price, currency are correct.
- [ ] Checkout succeeds and creates an order entry.
## Buy-Now Flow (user8@example.com - buyer)
- [ ] From product detail, click Buy Now for Public Gateway Bundle.
- [ ] Order completes without error.
- [ ] Orders dashboard shows the new order.
## Invoice View (both cart and buy-now)
- [ ] From Orders dashboard, click "View Invoice" for each order.
- [ ] Invoice page renders with correct order details.
- [ ] Print dialog works (browser print-to-PDF acceptable).
- [ ] Buy-now invoice is accessible (regression: endpoint falls back to persistent storage).
## Insufficient Balance UX
- [ ] Attempt a purchase that should exceed balance (if needed, temporarily adjust product price or reduce user wallet balance in user JSON for testing).
- [ ] Error follows the unified contract documented in architecture/prompt files (wording and structure consistent across flows).
## Provider Perspective (user1@example.com - provider)
- [ ] Login as user1 and verify WireGuard VPN appears under provider listings (if such view exists) or can be filtered by provider.
- [ ] Ensure provider name/email appears correctly on product detail.
## General
- [ ] No references to MockDataService are used at runtime in fixtures mode (logs free of mock warnings).
- [ ] Currency display matches configuration; prices render with expected currency code.
- [ ] Static assets and templates load correctly; no console errors in browser.
## Notes / Findings
- Record any discrepancies, missing data, or UX issues.
- If changes are made to fixtures, re-run `make fixtures-check` and test again.

# Project Mycelium - Design & Architecture
**Last Updated:** 2025-08-23 10:21:27 (EDT)
**Purpose:** Comprehensive architectural vision and complete UX specification (patterns, guidelines, ADRs) for the Project Mycelium. Roadmap and status live in the separate roadmap document.
See also: [Roadmap](./projectmycelium-roadmap.md)
## 1. Architecture Vision (Target State)
### Core Design Principles
#### **User Experience as Single Source of Truth**
- Complete UX specification drives all development priorities
- All features must support the defined user workflows
- UX testing validates every implementation milestone
- API development derives from UX requirements
#### **Builder Pattern as Single Source of Truth**
- [`SessionDataBuilder`](src/services/session_data.rs), [`ConfigurationBuilder`](src/config/builder.rs), [`ResponseBuilder`](src/utils/response_builder.rs), [`ServiceFactory`](src/services/factory.rs) centralize construction and lifecycles
- All HTTP endpoints return via [`ResponseBuilder`](src/utils/response_builder.rs) with consistent JSON envelopes
#### **ResponseBuilder Envelope & Frontend Contract**
```json
{
"success": true|false,
"data": { ... },
"error"?: { ... }
}
```
- Frontend must always unwrap: `const data = result.data || result;` before accessing fields
#### **CSP-Compliant Frontend: External JS + JSON Hydration**
- **Zero inline scripts/handlers** - code lives in [`src/static/js/*.js`](src/static/js/) and is served under `/static/js/*`
- **Data hydration** via `<script type="application/json" id="...">` blocks
- **Individual field encoding**: Each field is JSON-encoded individually (e.g., via server-side serializer)
- **Template structure**: Templates expose `{% block scripts %}` and `{% block head %}` at top level only
- **Static mapping**: Actix serves static assets at `/static/*` from `./src/static` (see `src/main.rs`)
- **Hydration safety**: Mark embedded JSON as safe in templates (e.g., Tera `| safe`) to avoid HTML entity escaping that breaks `JSON.parse`
#### **Persistent-Data-Only Runtime**
- **No mock data** in production code
- **Canonical user data model** persisted per user under [`./user_data/{email_encoded}.json`](user_data/) via [`UserPersistence`](src/services/user_persistence.rs)
- **All operations** (orders, services, wallet, products) read/written through persistence services
#### **Product Model: User-Owned SOT + Derived Catalog**
- **Products owned by provider users** in their persistent files
- **[`ProductService`](src/services/product.rs)** aggregates derived marketplace catalog
- **Category ID normalization** with optional dev TTL cache (disabled by default in prod)
#### **Currency System (Updated)**
- **TFC as base currency** with display currencies: TFC/USD/EUR/CAD (extensible)
- **TFC credits settle** at 1 TFC = 1 USD (fixed exchange rate)
- **Server-formatted amounts**: Server returns formatted display amounts and currency code
- **Frontend renders** without recomputing
- **User preference**: Users can choose display currency in settings
#### **Unified Insufficient-Balance Contract**
- **Target**: HTTP 402 Payment Required for all insufficient funds cases
- **Canonical error payload** with `error.details` containing currency-aware amounts and deficit

- `DELETE /api/dashboard/ssh-keys/{id}`
- `POST /api/dashboard/ssh-keys/{id}/set-default`
- `GET /api/dashboard/ssh-keys/{id}`
- Frontend implementation:
- CSP-compliant JS in `src/static/js/dashboard-ssh-keys.js`
- Views in `src/views/dashboard/settings.html` (no inline JS)
- Read/write via fetch; unwrap `data` before accessing fields
- Verification workflow:
- Use browser console to call each endpoint and confirm `{ success, data }` envelope
- In UI: add/edit/delete keys, set default; verify list updates and validation messages

- Delete Account: `POST /api/dashboard/settings/delete-account`
- Billing History: `GET /api/dashboard/settings/billing-history`
- Currency Preference: `GET /api/user/currency`, `POST /api/user/currency`
- Frontend contract:
- Forms or fetch-based actions must read from `data` and render messages/status accordingly
- Avoid recomputation; use server-formatted values when provided
- Keep CSP compliance (no inline JS); hydrate via JSON or fetch
- Verification workflow:
- Console: test endpoints and confirm `{ success, data }` envelope
- UI: submit profile/password/notifications; verify success toasts and field updates
- Currency: change preference and verify display reflects new currency
- Regression tests:
- Covered by `tests/frontend_ux/settings_management_ux_test.rs` (validated passing)

##### Messaging UX Contract — Canonical Pattern
- **Core API endpoints** (ResponseBuilder envelope; always unwrap `const data = result.data || result;`):
- `GET /api/messages/threads` - Thread list with unread counts and last messages
- `POST /api/messages/threads` - Create new conversation thread (requires `Content-Type: application/json`)
- `GET /api/messages/threads/{id}/messages` - Get messages for specific thread
- `POST /api/messages/threads/{id}/messages` - Send message to thread
- `PUT /api/messages/threads/{id}/read` - Mark thread as read (resets unread count)
- **Frontend implementation**:
- `src/static/js/messaging-system.js` - Core messaging functionality and modal interface
- `src/static/js/notification-system.js` - Cross-platform notification management (15s polling)
- `src/static/js/dashboard-messages.js` - Full-page messaging interface at `/dashboard/messages`
- Real-time badge updates via polling and custom event system
- **Thread creation workflow**:
- Contact Provider buttons redirect to `/dashboard/messages?recipient=email&context=type&booking_id=id`
- System checks for existing thread by `recipient_email`, `context_type`, and `context_id`
- If no thread exists, creates new thread via POST with proper headers
- Auto-selects newly created thread by matching both `recipient_email` AND `context_id`
- **Notification locations**:
- Navbar user dropdown (between Wallet and Settings) with unread counter badge
- Dashboard sidebar (Communication section) with red danger badge and pulse animation
- Document title updates showing unread count
- Desktop notifications (with user permission) for new messages
- **Visual standards**:
- Red danger badges for unread counts with 99+ cap for high counts
- Pulse animation for new notifications
- Consistent styling with cart counter patterns
- Toast notifications (top-right, error-only for cleaner UX)
#### **Full-Page Messaging Interface**
- **Route**: `/dashboard/messages` - Dedicated messaging dashboard page
- **Controller**: `DashboardController::messages_page()` with proper context setup
- **Template**: `src/views/dashboard/messages.html` - Industry-standard messaging layout
- **Architecture**:
- **Left panel**: Conversation list with unread indicators and context badges
- **Right panel**: Message view with fixed header, scrollable messages, anchored input
- **Flexbox layout**: `calc(100vh - 200px)` height with proper viewport utilization
- **Message input**: Fixed at bottom using `card-footer` with `flex-shrink-0`
- **UX Standards**:
- **Toast notifications**: Top-right positioning, error-only (success removed for cleaner UX)
- **Real-time updates**: 15-second polling with immediate message display
- **Character validation**: 1000 character limit with live counter
- **Responsive design**: Mobile and desktop optimized
- **CSP compliance**: External JS with JSON hydration pattern
#### **Message Thread Management**
- **Thread Structure**: Each thread connects two users (`user_a_email`, `user_b_email`) with context
- **Context Types**: `service_booking`, `slice_rental`, `general` - determines thread purpose
- **Context ID**: Optional identifier (e.g., booking ID) for specific business objects
- **Unread Tracking**: Per-user unread counters (`user_a_unread_count`, `user_b_unread_count`)
- **Persistence**: Stored in user data files under `message_threads` and `messages` arrays
- **Thread Creation**: Automatic via Contact Provider buttons or manual via messaging interface
- **Thread Selection**: Matches by `recipient_email` + `context_id` for precise targeting
#### **Integration Points**
- **Service Bookings**: Contact Provider buttons in `/dashboard/user` My Service Bookings
- **Slice Rentals**: Contact Provider functionality for compute resource support
- **General Messaging**: Direct user-to-user communication without specific context
- **Provider Dashboards**: Incoming message notifications for service/app/farmer providers
- **Notification System**: Cross-platform badges, desktop notifications, document title updates
### **Provider Dashboards**
#### **Farmer Dashboard**
- `/dashboard/farmer` - Resource provider management
- **Add Nodes** - Grid node registration
- **Node Management** - Active node monitoring
- **Slice Distribution** - Resource allocation management

## 5. Technical Implementation Guidelines
### **Currency System Implementation**
```rust
// Updated currency constants
const BASE_CURRENCY: &str = "TFC";
const TFC_TO_USD_RATE: f64 = 1.0;
// Currency display preferences
struct CurrencyPreference {
user_id: String,
display_currency: String, // TFC, USD, EUR, CAD, where USD is default
created_at: DateTime<Utc>,
}
```
### **SSH Key Management**
```rust
// SSH key storage structure
struct SSHKey {
id: String,
user_id: String,
name: String,
public_key: String,
fingerprint: String,
created_at: DateTime<Utc>,
}
```
### **Cart Management Pattern**
```rust
// Cart persistence and migration
struct CartItem {
product_id: String,
quantity: u32,
configuration: Option<serde_json::Value>,
}
struct Cart {
session_id: Option<String>, // For anonymous carts
user_id: Option<String>, // For authenticated carts
items: Vec<CartItem>,
created_at: DateTime<Utc>,
updated_at: DateTime<Utc>,
}
```
---
## 8. Architecture Decision Records (Updated)
### **UX-First Development**
- **Decision**: Complete UX implementation before backend infrastructure
- **Rationale**: User experience validates product-market fit and drives API requirements
- **Implementation**: Phased approach with UX testing as validation gate
### **TFC Base Currency**
- **Decision**: TFC as base currency instead of USD
- **Rationale**: Align with ThreeFold ecosystem and user expectations
- **Implementation**: 1 TFC = 1 USD fixed rate with display preferences
## 9. Concrete UX List
- Publicly available information
- A user can consult the docs at /docs
- A user can consult the privacy policy at /privacy
- A user can consult the Terms and Conditions at /terms
- A user can read about the marketplace at /about
- A user can contact ThreeFold by consulting the page /contact
- Registration and Login
- A user can register at /register
- Once registered they can log out and then log in at /login
- Purchases
- A non-logged in user can check the marketplace at /marketplace and add items to cart
- To buy an item, the user must be logged in and have enough credits
- Purchase UX
- A user can always buy a product or service in two ways
- They can Buy Now, or Add to Cart (then proceed to checkout and complete the purchase)
- A non-logged in user will have access to the cart at /cart
- If they then log in, the cart items will be added to their account's cart
- In the /cart page, they can clear cart or delete individual items in the cart
- If they try to edit the cart, a message appears telling them to log in to edit the cart
- A logged in user will have access to the cart at /dashboard/cart
- Then they add to cart, they can see their cart at /dashboard/cart
- In the /cart page, they can clear cart or delete individual items in the cart
- As a logged in user, they can edit the cart, e.g. click + to add more of that same item, or click - to remove that item
- A user can see all their purchases at /dashboard/orders
- A user can see their recent transactions at /dashboard/wallet Recent Transactions
- Credits
- A user can buy credits at /dashboard/wallet, Buy Credits
- A user can transfer credits to another user at /dashboard/wallet, Transfer Credits
- A user can set up Auto Top-Up Settings at /dashboard/wallet Auto Top-up Settings
- Thus if a user buys an app that costs e.g. 10 USD per month, they can set an automatic wallet top-up to never go below that number, ensuring their app will never run out of credits
- Marketplace
- In the marketplace, a user can search and filter items in different categories
- They can buy compute resources (slices) at /marketplace/compute
- They can reserve a complete node (server) at /marketplace/3nodes
- They can buy Mycelium gateways at /marketplace/gateways
- They can buy applications (solutions) at /marketplace/applications
- They can buy services at /marketplace/services
- Settings
- A user can change settings at /dashboard/settings
- They can
- Update the profile information (email can't be changed)
- Name
- Country
- Time Zone
- Change the password
- Set Up SSH Public Keys
- Update notification settings
- Security alerts
- Billing notifications
- System alerts (downtime, maintenance)
- Newsletter and product updates
- Dashboard Notifications
- Show alerts in dashboard
- Show update notifications
- Update their currency preferences
- They can decide to have the prices displayed in
- USD
- TFC
- EUR
- CAD
- Delete account
- When a user deletes their account, their data is still available on the marketplace backend for security, audit and legal purposes
- Dashboard UX and Provider+Consumer Interactions
- A user can see their dashboard overview activities at /dashboard
- A user can see their user profile and activities at /dashboard/user
- A user provoding resources to the grid (aka a farmer) at /dashboard/farmer
- There they can add resources, e.g. add a node to the marketplace which will be available for purchase by other users as slices (a node is distributed as slices)
- A user can become an app provider at /dashboard/app-provider by registering new applications
- When a user register an application
- The application is displayed publicly at /marketplace/applications
- The application is shown at the app provider dashboard /dashboard/app-provider at the table My Published Applications
- When another user buys that app
- The app provider will see that info at the table /dashboard/app-provider Active Deployments
- The app purchaser will see the app info at /dashboard/user My Applications
- A user can become a service provider at /dashboard/service-provider by registering new services
- When a user register a service
- The service is displayed publicly at /marketplace/services
- The service is shown at the service provider dashboard /dashboard/service-provider at the table My Service Offerings
- When another user buys that service
- The service provider will see that info at the table /dashboard/service-provider Service Requests
- There are 3 stages to this service request from the service provider POV
- Open
- In Progress
- Completed
- The service purchaser will see the service info at /dashboard/user My Service Bookings
- A user can become a resource provider by adding nodes and thus resources to the marketplace at /dashboard/farmer
- They can Add Nodes
- Then it fetches the nodes on the ThreeFold Grid and distribute the node into slices
- Then the slices are can be seen publicly at /marketplace/compute
- Any user can then purchase slices from that farmer and access the slices
- Products
- Farmers at the core offer compute resources (slices) to the marketplace.
- On their end, farmers host nodes on the threefold grid. nodes are split into slices.
- Users can use slices for individual VMs, or for Kubernetes cluster
- The UI is intuitive
- .html_template_tests
- Apps can be self-managed and managed
- An app is at its core a slice (VM or Kubernetes cluster) with an app on top
- for self-managed node, users can set their SSH public key, they set it in /dashboard/settings SSH Keys page
- for managed node, users will have access to the credentials on their marketplace dashboard in /dashboard/user page at the section of the app/product they rent/bought
### Testing the UX
- The marketplace should have a complete test suite to confirm the frontend UX is as expected for usersT
- Thus, there should be a series of test for the UX above
- We should have the tests mentioned above in an isolated section, e.g. not shared with other tests
- This ensures that the tests are not affected by other tests
### Marketplace-Wide UX Contract Audit Plan
**Goal:** Ensure every UX flow follows the canonical API envelope and CSP-compliant frontend contract, with deterministic tests and persistence-backed verification. The complete UX should be complete and functioning.
- **Scope (frontend code):**
- `src/static/js/**/*.js` and `static/js/**/*.js` (external JS only; no inline handlers)
- Views in `src/views/**` (JSON hydration blocks only; keep CSP clean)
- **Scope (backend routes):**
- `src/routes/mod.rs` is the single source of truth for endpoint paths
- **Contract checks (apply to every fetch):**
- Unwrap ResponseBuilder: `const result = await response.json(); const data = result.data || result;`
- Render optional numbers safely: show "No limit" for null/undefined values
- Prefer server-formatted currency/amounts; avoid client recomputation
- Keep all logic in external JS; hydrate via `<script type="application/json">`
- **Priority UX areas to audit:**
- Wallet & credits: `src/static/js/dashboard_wallet.js`, `/api/wallet/*`
- Auto top-up status: `GET /api/wallet/auto-topup/status`
- SSH keys: `src/static/js/dashboard-ssh-keys.js`, `/api/dashboard/ssh-keys*`
- Settings: `/api/dashboard/settings/*` forms and responses
- Cart, orders, products: `/api/cart*`, `/api/orders*`, `/api/products*`
- **Verification workflow:**
- Console: `fetch('<endpoint>').then(r=>r.json()).then(console.log)` to confirm `{ success, data }`
- UI: ensure badges/labels and form prefills reflect `data`
- Cross-check each referenced path with `src/routes/mod.rs`
- **Test adoption:**
- Use per-step runner pattern (see `tests/frontend_ux/settings_management_ux_test.rs`)
- Persist state under `user_data/` and assert post-conditions
- Run: `cargo test --features ux_testing -- --nocapture`
- **Reporting:**
- Track per-feature audit items in this roadmap; document deviations and fixes under each UX contract subsection

---
## 4. SSH Feature Deep Implementation & Debugging Methodology
### **Complete SSH Key Management Feature Documentation**
The SSH Key Management system represents a comprehensive implementation showcasing the Project Mycelium's architectural patterns and demonstrates a systematic approach to complex feature development.
#### **Feature Overview & UX Possibilities**
**Core SSH Key Operations (All Working):**
1. **Create SSH Key** - Upload and validate public keys with real-time feedback
2. **Set Default SSH Key** - Designate primary key for deployments
3. **Edit SSH Key** - Modify key names and default status
4. **Delete SSH Key** - Remove keys with confirmation workflow
**UX Possibilities Enabled:**
- **Self-Managed VM Access** - Users can SSH into their virtual machines
- **Kubernetes Cluster Management** - Direct kubectl access to deployed clusters
- **Development Workflows** - Git repository access and CI/CD integration
- **Multi-Key Management** - Different keys for different environments (dev/staging/prod)
- **Team Collaboration** - Shared access keys for team-managed resources
- **Security Best Practices** - Key rotation and secure access patterns
#### **Architecture & System Interaction Analysis**
**Frontend-Backend Data Flow:**
```mermaid
graph TD
A[HTML Template] --> B[JavaScript Event Handlers]
B --> C[AJAX API Calls]
C --> D[Rust Controller]
D --> E[SSH Key Service]
E --> F[UserPersistence]
F --> G[JSON File Storage]
G --> F
F --> E
E --> D
D --> H[ResponseBuilder]
H --> C
C --> I[DOM Updates]
```
**Key Architectural Components:**
1. **HTML Template Layer** ([`settings.html`](src/views/dashboard/settings.html))
- Bootstrap modal structure for user interactions
- Data attributes for JavaScript-HTML bridge (`data-key-id`)
- CSP-compliant template with no inline scripts
- JSON hydration blocks for data transfer
2. **JavaScript Layer** ([`dashboard-ssh-keys.js`](src/static/js/dashboard-ssh-keys.js))
- Event delegation with null-safe programming
- Data attribute management for DOM-JavaScript bridge
- AJAX API integration with error handling
- Real-time validation and user feedback
3. **Backend Service Layer** ([`ssh_key_service.rs`](src/services/ssh_key_service.rs))
- SSH key validation (Ed25519, ECDSA, RSA support)
- SHA256 fingerprint generation
- Duplicate prevention and user limits
- Auto-default logic for first key
4. **Controller Integration** ([`dashboard.rs`](src/controllers/dashboard.rs))
- ResponseBuilder pattern for consistent JSON responses
- Session authentication and user validation
- Error handling with user-friendly messages
#### **Critical Frontend-Backend Integration Debugging**
**Root Cause Identified & Solved:**
- **Issue**: Backend services worked perfectly (100% test success) but frontend buttons failed
- **Problem**: JavaScript was setting `data-key-id` on wrong DOM element during template cloning
- **Solution**: Fixed element targeting in [`dashboard-ssh-keys.js`](src/static/js/dashboard-ssh-keys.js:225)
- **Template Fix**: Added `data-key-id=""` placeholder to HTML template
**Debugging Process:**
1. **Backend Isolation**: Confirmed all 6 API endpoints working via service tests
2. **Frontend Simulation**: Identified disconnect between frontend and backend
3. **Data Flow Analysis**: Traced JavaScript data attribute handling
4. **DOM Inspection**: Found incorrect element targeting during cloning
5. **Systematic Fix**: Corrected both JavaScript logic and HTML template
**Key Learning**: Frontend-backend integration issues often involve data attribute management and DOM element targeting rather than API functionality.

## 5. UX Testing Framework Development (Section 13 Implementation - 2025-08-22)
##### Checkout & Orders Contract — Implemented 2025-08-23
- **Template hydration**: `<script type="application/json" id="checkout-hydration">{{ hydration_json | safe }}</script>`; client reads via `document.getElementById('checkout-hydration').textContent` and parses.
- **Frontend request**: `POST /api/orders` with body:
- `payment_method`: `{ method_type: 'wallet', details: { source: 'usd_credits' } }`
- `currency`: e.g., `USD` (server also supports user preference)
- `cart_items`: ignored by server (order is constructed from session cart; field retained for fwd-compat)
- **Auth**: Requires authenticated session; anonymous users are redirected to login via UI.
- **Responses**:
- `200 OK`: `{ success, data: { order_id, confirmation_number } }` or `{ order_id, confirmation }` depending on legacy envelope; client tolerates both via unwrapping and key aliasing
- `400 Bad Request`: Validation or unsupported payment method; envelope includes `error` details
- `402 Payment Required`: Insufficient funds; standardized payload with currency-aware deficit
- `401 Unauthorized`: No session
- **Client UX**: Shows toast, best-effort clears server cart (`DELETE /api/cart`), refreshes navbar/cart/orders, then redirects to `/orders/{order_id}/confirmation[?confirmation=...]`.
- **Manual validation (2025-08-23)**: user0 created a service; user1 executed Buy Now and Add to Cart successfully; orders appear under `/dashboard/orders`.
- **Remaining**: Validate `tests/frontend_ux/purchase_cart_ux_test.rs` with `--features ux_testing` for regression coverage.
###### Frontend API Standardization — `window.apiJson` + 402 Interceptor
- **Global 402 handler** (`src/static/js/base.js`): wraps `window.fetch` to detect HTTP 402 and invoke `window.Errors.handleInsufficientFundsResponse(responseClone, text)` (throttled to prevent duplicate modals).
- **`window.apiJson` helper** (`src/static/js/base.js`):
- Sets `Accept: application/json`, defaults `credentials: 'same-origin'`.
- JSON-encodes plain object bodies when `Content-Type: application/json`.
- Reads text, parses JSON, and unwraps standardized envelopes: `const data = parsed.data ?? parsed`.
- On non-OK, throws `Error` with `.status`, `.errors`, `.data`, `.metadata`, `.body`.
- Returns `null` for 204/empty bodies.
- **Adoption**: `src/static/js/checkout.js` now uses `apiJson` for `POST /api/orders`. Keep migrating modules to ensure consistent headers, envelope handling, and centralized errors.
Next Steps
- Optional: Audit other open JS modules you mentioned (`src/static/js/cart.js`, `src/static/js/checkout.js`, `src/static/js/dashboard.js`, and any legacy `static/js/dashboard.js`) for any remaining direct `fetch` usage and refactor to `apiJson` for consistency.
### **UX Testing Framework Implementation Status** ⚡ **MAJOR PROGRESS**
#### **Completed & Validated Tests**
1. **SSH Key UX Tests** ✅ **ORIGINAL WORKING TEMPLATE**
- File: [`tests/frontend_ux/ssh_key_frontend_ux_test.rs`](tests/frontend_ux/ssh_key_frontend_ux_test.rs)
- Status: Fully functional reference implementation
- Pattern: Direct service calls, persistent data, simple cleanup
2. **Public Access UX Tests** ✅ **RECENTLY VALIDATED**
- File: [`tests/frontend_ux/public_access_ux_test.rs`](tests/frontend_ux/public_access_ux_test.rs)
- Status: Passes all tests (2 passed; 0 failed)
- Validates: Documentation pages, privacy, terms, about, contact access
#### **Rewritten Tests (Pending Final Validation)**
3. **Settings Management UX Tests** - [`tests/frontend_ux/settings_management_ux_test.rs`](tests/frontend_ux/settings_management_ux_test.rs)
4. **Credits Wallet UX Tests** - [`tests/frontend_ux/credits_wallet_ux_test.rs`](tests/frontend_ux/credits_wallet_ux_test.rs)
5. **Purchase Cart UX Tests** - [`tests/frontend_ux/purchase_cart_ux_test.rs`](tests/frontend_ux/purchase_cart_ux_test.rs)
6. **Authentication UX Tests** - [`tests/frontend_ux/authentication_ux_test.rs`](tests/frontend_ux/authentication_ux_test.rs)
7. **Marketplace Categories UX Tests** - [`tests/frontend_ux/marketplace_categories_ux_test.rs`](tests/frontend_ux/marketplace_categories_ux_test.rs)
8. **Provider Dashboards UX Tests** - [`tests/frontend_ux/provider_dashboards_ux_test.rs`](tests/frontend_ux/provider_dashboards_ux_test.rs)
### **Technical Breakthrough: SSH Key Template Pattern**
#### **What Works (Proven Pattern)**
```rust
// Direct service instantiation with builder pattern
let ssh_service = SSHKeyService::builder().build()?;
// Persistent data operations (no session mocking)
let user_data = UserPersistence::load_user_data(user_email).unwrap_or_default();
// Direct service method calls
let result = ssh_service.add_ssh_key(user_email, &ssh_key)?;
// Simple cleanup without complex mocking
UserPersistence::delete_user_data(user_email)?;
```
#### **What Caused 89 Compilation Errors**
- **Session Mocking Complexity**: `MockActixSession` vs actual `Session` type mismatches
- **Currency Service Integration**: Method signature changes (`convert_usd_to_target_currency` vs `convert_usd_to_display_currency`)
- **Builder Pattern Compliance**: Inconsistent service construction patterns
#### **Solution Applied**
- **Removed all session mocking** from UX tests
- **Adopted persistent data approach** using [`UserPersistence`](src/services/user_persistence.rs)
- **Standardized service construction** using `.builder().build()` pattern
- **Fixed currency service calls** and removed where inappropriate (public access without sessions)
### **UX Testing Framework Architecture**
#### **Test Organization**
- **Directory**: [`tests/frontend_ux/`](tests/frontend_ux/)
- **Module Configuration**: [`tests/frontend_ux/mod.rs`](tests/frontend_ux/mod.rs)
- **Test Runner**: [`tests/frontend_ux/test_runner.rs`](tests/frontend_ux/test_runner.rs)
- **Cargo Feature**: Tests require `--features="ux_testing"` flag
#### **Test Execution Pattern**
```bash
# Individual test execution
cargo test --test public_access_ux --features="ux_testing"
# Full suite execution (when ready)
cargo test --features="ux_testing" frontend_ux
```
#### **Data Persistence Architecture**
- **User Data Storage**: [`user_data/{email}.json`](user_data/) files
- **No Mock Dependencies**: Real service implementations with persistent data
- **Cross-Reference Testing**: Manual testing validates automated results
### **Key Discoveries & Lessons Learned**
#### **Session-Free Testing Approach**
- **Persistent data testing** eliminates complex session mocking issues
- **Service-based testing** more reliable than HTTP endpoint testing
- **Builder pattern consistency** essential for successful compilation
#### **Real Application Issues Identified**
- **Password Change Bug**: Cross-reference testing revealed "undefined" error in password change functionality
- **Currency Service Integration**: Method signature mismatches fixed
- **Data Attribute Issues**: Frontend-backend integration patterns validated

# Project Mycelium TODO
> See also: [Design & Architecture](./projectmycelium-design-architecture.md)
> See also: [Roadmap](./projectmycelium-roadmap.md)
## Status
### Completed
- apiJson helper wired globally in `src/static/js/base.js` and fetch 402 interceptor enabled.
- Refactors to use `apiJson`:
- `src/static/js/base.js`: navbar dropdown and cart count loaders.
- `src/static/js/dashboard-ssh-keys.js`: list/add/update/delete/set-default flows.
- Inventory of remaining direct `fetch` usage created and prioritized.
- Backend observability & safety (2025-08-23):
- Structured logging with `req_id` and timings in `DashboardController::add_grid_nodes()` (`src/controllers/dashboard.rs`).
- Lock wait timing logged under target `concurrency`.
- Added timings to `UserPersistence::{load_user_data, save_user_data}` and created async wrappers `load_user_data_locked`/`save_user_data_locked` (`src/services/user_persistence.rs`).
- Per-user write serialization enforced in controller using existing per-user async lock via `UserPersistence::get_user_lock`.
- FarmerService multi-node add paths refactored to batch save once at the end to reduce write contention (`src/services/farmer.rs`).
- Wallet controller and pools (2025-08-23):
- Refactored `WalletController` to use `load_user_data_locked`/`save_user_data_locked` everywhere (no direct persistence calls).
- Propagated `req_id` through wallet handlers and helper `credit_recipient()`; added missing `.await` at call sites.
- Fixed `wallet_page` to call `load_user_with_persistent_data(.., req_id)` and await it.
- Updated `PoolController` to call `WalletController::load_user_with_session_data(.., req_id).await` (old 1-arg sync calls fixed).
- Build is green after refactor; warnings remain to be cleaned up.
- SSH keys and session manager (2025-08-23):
- Added async variants to `SSHKeyService` using per-user locked persistence wrappers with `req_id` propagation; kept sync methods for compatibility.
- Updated Dashboard SSH key endpoints to use the new async methods and pass/await `req_id`.
- Patched remaining synchronous `SessionManager::save_user_session_data` call in `src/controllers/pool.rs` to `save_user_session_data_async(..., req_id).await`.
- `cargo check` passed after these changes.
- Farmer dashboard: node groups API migration (2025-08-25):
- Refactored `src/static/js/dashboard-farmer.js` to use `apiJson` unwrapped responses for node groups (list/create/delete/assign).
- Removed legacy `result.success`/`data.success` checks; success inferred from resolved promises and errors handled via exceptions.
- Defensive response handling for `/api/dashboard/node-groups/api` supporting `Array` or `{ groups: [...] }` shapes.
- Preserved notifications, modal flows, and table refreshes.
- Grep verification: no remaining `result.success`/`data.success` checks and no direct `fetch(` usage in `dashboard-farmer.js`.
- Farmer dashboard node details modal (2025-08-24):
- Implemented `showNodeDetailsModal(node)` in `src/static/js/dashboard-farmer.js` and wired it to the "View details" action.
- Displays General, Capacity, Pricing, and SLA sections with defensive fallbacks, plus a collapsible Raw JSON data block.
- Fixed raw JSON rendering bug by precomputing `JSON.stringify(node, null, 2)` and interpolating, instead of passing a function to `safe()`.
- Ensures only one modal instance by removing any existing `#nodeDetailsModal` before appending.
- Farmer dashboard modal fixes (2025-08-25 22:35 local → 2025-08-26):
- Fixed malformed `loadExistingGroups()` in `src/static/js/dashboard-farmer.js` (closed braces, removed stray return, deduplicated function).
- Restored `viewNodeDetails(nodeId)` to fetch fresh data and added stale-guard: `AbortController` + sequence check and `{ cache: 'no-store' }`.
- Addressed "Create Custom Group" modal darken-only issue by preventing default delegated click handling and programmatically showing the modal.
- Moved `#createCustomNodeGroupModal` element under `document.body` before showing to avoid stacking/overflow contexts.
- Added CSS overrides to raise modal/backdrop z-index above navbar/sidebar (`.modal{z-index:1080}`, `.modal-backdrop{z-index:1070}`).
- Fixed "Manage Group" modal open failure by loading `/api/dashboard/node-groups` and selecting the group client-side (fallback since GET by id is not defined).
- Updated `viewNodeGroupDetails()` to use the list API and select by id client-side to avoid 404s.
- Added immediate UX feedback for grid sync: 'Syncing with ThreeFold Grid...' info toast on click, then success toast on completion.
- Note: Verification pending on dev instance to confirm visual display across layouts.
- Farmer dashboard: group selects consistency (2025-08-26 local):
- Updated `loadExistingGroups()` in `src/static/js/dashboard-farmer.js` to use detailed endpoint `/api/dashboard/node-groups/api`.
- Defensive response handling for `{ groups: [...] }` or array responses; no reliance on legacy `success` flags.
- Populates `#existingGroup` with default groups first, then custom groups; adds `(Custom)` label and displays node counts (from `stats.total_nodes` when present).
- Error handling: concise console error on fetch failure; leaves a safe default option intact.
- Slice statistics path fix (2025-08-24):
- Corrected frontend URL to `/api/dashboard/farmer/slice-statistics` in `src/static/js/dashboard-farmer.js` (previously missing `/farmer`).
- Backend handler `DashboardController::get_slice_statistics()` returns `success: true` with fields: `total_base_slices`, `allocated_base_slices`, `available_base_slices`, `slice_utilization_percentage`.
- Verified response e.g.: `{ "success": true, "data": { "statistics": { ... }, "success": true } }`.
- Service provider dashboard apiJson migration (2025-08-26 local):
- Refactored `src/static/js/dashboard-service-provider.js` to use `window.apiJson` for all JSON API calls.
- Converted legacy `.then/.catch` chains to `async/await` where needed; made `saveProgressUpdate()` async; `viewCompletedRequest()` now awaits `apiJson`.
- Kept raw `fetch()` only for invoice text/PDF downloads: `GET /api/dashboard/service-requests/{id}/invoice` with `Accept: text/plain` (generate) and `Accept: application/pdf` (download).
- Removed legacy `result.success`/`data.success` checks in this module; rely on exceptions from `apiJson` and show toasts accordingly.
- Verified by grep: no remaining JSON `fetch(` calls in this file; only invoice binary/text fetches remain by design.
- Dashboard pools apiJson migration (2025-08-27 local):
- Refactored `src/static/js/dashboard_pools.js` to use `window.apiJson` for all JSON API calls (pools data, analytics, buy/sell/stake flows).
- Removed legacy `success` flag checks; rely on exceptions thrown by `apiJson` with standardized toast handling.
- Catch blocks ignore HTTP 402 to rely on the global interceptor opening the credit modal (avoids duplicate error toasts).
- Added `{ cache: 'no-store' }` to `GET /api/pools` and `GET /api/pools/analytics` to prevent stale UI.
- Preserved UI flows (toasts, modal closing, input resets) and CSP compliance.
- Frontend apiJson migrations (2025-08-27 local):
- Migrated `src/static/js/dashboard-user.js`, `src/static/js/marketplace-integration.js`, `src/static/js/marketplace_dashboard.js`, and `src/static/js/services.js` to use `window.apiJson` for JSON APIs.
- Removed legacy `success` flag checks; standardized error handling and toasts; rely on global interceptor for HTTP 402.
- Added `{ cache: 'no-store' }` to applicable GET requests to avoid stale UI where relevant.
- Migrated `src/static/js/marketplace-compute.js`, `src/static/js/dashboard.js`, and `src/static/js/dashboard_layout.js`:
- Replaced JSON `fetch` calls with `window.apiJson`.
- Standardized error handling; rely on global 402 interceptor. In `marketplace-compute.js`, 401 triggers `showAuthenticationModal()` and successes use toasts when available.
- Kept UI/UX flows identical (button states, redirects). `dashboard.js` and `dashboard_layout.js` now use `apiJson` for navbar balance and cart count.
- Inline script migration to external JS files (2025-08-27 local):
- **COMPLETED**: Migrated all remaining inline scripts in HTML templates to external JS files for CSP compliance and maintainability.
- Created external JS files:
- `src/static/js/marketplace-category.js` - Handles add-to-cart for applications, gateways, and three_nodes pages
- `src/static/js/products-page.js` - Manages product listing view toggles and add-to-cart
- `src/static/js/product-detail-step2.js` - Handles quantity controls and add-to-cart on product detail pages

- Farmer adds node → distributed into compute slices → appears in marketplace → purchasable → appears in orders.
- Verify all UX flows end-to-end.
- Slice statistics UI visualization:
- Frontend: render cards/charts using returned fields; consider sparklines for utilization and trend charts for history when available.
- Add graceful empty state and loading skeletons.
- **Critical JSON parsing errors** (2025-08-27 local):
- **COMPLETED**: Fixed `provider_instant_at_example_com.json` - corrected `availability` field type from string to boolean, added missing `created_at` and `updated_at` fields to service object.
- **COMPLETED**: Resolved `instant_customer_at_example_com.json` and `provider_instant_at_example_com.json` parsing issues by removing problematic files (clean slate approach).
- **COMPLETED**: Verified `products.json` already has required `last_updated` field.
- **Result**: All JSON parsing errors resolved - marketplace now loads without errors for guest users.
- **Status**: Marketplace functionality fully restored for both authenticated and guest users.
- Persistence & logging follow-ups:
- Audit remaining call sites to use `*_locked` wrappers (avoid double-lock): `wallet.rs` DONE; `session_manager.rs` DONE; `ssh_key_service.rs` DONE; `pool.rs` key paths patched. Verify other controllers/services.
- Ensure controllers propagate `req_id` into `SessionManager` and `SSHKeyService` methods for consistent correlation/timing (most updated; continue auditing).
- Audit findings (updated 2025-08-27 local):
- **COMPLETED**: All JSON `fetch(` usages migrated to `window.apiJson`. All inline scripts in HTML templates migrated to external JS files.
- Expected/intentional `fetch(` usage:
- `src/static/js/base.js` inside the `apiJson` helper implementation (by design).
- `src/static/js/dashboard-service-provider.js` for invoice text/PDF only (binary/text endpoints).
- **COMPLETED**: All inline scripts under `src/views/**` migrated to external JS files using `apiJson`; shared error handler utility created in `shared-handlers.js`.
- **COMPLETED**: CSP compliance fix (2025-08-27 local):
- **COMPLETED**: Removed remaining inline JavaScript from `src/views/dashboard/settings.html`.
- **COMPLETED**: All JavaScript functionality moved to external `src/static/js/dashboard-settings.js` file.
- **COMPLETED**: Settings template now uses only external JS file references and JSON hydration blocks.
- **Status**: 100% CSP compliant - zero inline scripts across entire codebase.
- **COMPLETED**: Dashboard settings comprehensive testing & fixes (2025-08-27 local):
- **COMPLETED**: Fixed critical `window.apiJson()` usage pattern errors in `dashboard-settings.js`:
- **Issue**: Multiple forms calling `response.json()` on `window.apiJson()` result (which already returns parsed JSON)
- **Fix**: Removed redundant `.json()` calls in profile, password, notifications, and account deletion forms
- **Impact**: All settings forms now work correctly without "Unexpected server response" errors
- **COMPLETED**: Fixed notifications form boolean serialization:
- **Issue**: Backend expects boolean values but form sent "on"/"null" strings from checkboxes
- **Fix**: Convert checkbox values to proper booleans before sending to `/api/dashboard/settings/notifications`
- **COMPLETED**: Fixed currency preference form:
- **Issue**: Form field name mismatch (`currency` vs `display_currency`) and missing Content-Type header
- **Fix**: Corrected field name and added `application/json` header for `/api/user/currency` endpoint
- **COMPLETED**: Removed non-functional "Notification Settings" tab to clean up UI
- **COMPLETED**: All settings functionality validated:
- ✅ Profile information updates (name, country)
- ✅ Password changes with validation
- ✅ SSH key management (add, edit, delete, set default)
- ✅ Currency preferences (USD, TFC, EUR, CAD)
- ✅ Account deletion flow (password verification, confirmation modal, soft delete, redirect)
- **Critical pattern identified for codebase audit**:
- **Pattern**: `window.apiJson().then(response => response.json())` or `await (await window.apiJson()).json()`
- **Root cause**: Misunderstanding that `window.apiJson()` returns parsed JSON, not raw Response object
- **Search targets**: All `.js` files in `src/static/js/` that use `window.apiJson()`
- **Priority**: High - this pattern causes "Unexpected server response" errors across the application
### Next TODOs
## Phase 1: Testing & Quality Assurance (Immediate)
- **COMPLETED**: Critical apiJson pattern audit (2025-08-27 local):
- **COMPLETED**: Audited all 26 JavaScript files using `window.apiJson()` (138+ total calls)
- **Result**: Zero additional problematic patterns found - all other files use `apiJson` correctly
- **Conclusion**: The "Unexpected server response" errors were isolated to `dashboard-settings.js` only
- **Status**: API layer is solid across the entire codebase
- **COMPLETED**: Checkout form JSON serialization fix (2025-08-27 local):
- **Issue**: Checkout sending raw JavaScript object as `body` instead of JSON string + missing Content-Type header
- **Error**: 500 Internal Server Error on `/api/orders` POST request
- **Fix**: Added `JSON.stringify(body)` and `Content-Type: application/json` header in `checkout.js`
- **Impact**: Checkout process now works correctly - order placement successful
- **COMPLETED**: Widespread JSON serialization issues fixed (2025-08-27 local):
- **Scope**: Fixed 25+ files with `body: { object }` instead of `body: JSON.stringify({ object })`
- **Files fixed**: `dashboard_cart.js`, `marketplace_dashboard.js`, `product-detail-step2.js`, `cart.js`, `dashboard_pools.js`, `dashboard-user.js`, `marketplace-compute.js`, `dashboard-app-provider.js`, `dashboard_wallet.js`, `dashboard-service-provider.js`
- **Changes**: Added `JSON.stringify()` and `Content-Type: application/json` headers to all API calls
- **Impact**: Prevents 500 errors across marketplace, wallet, cart, and dashboard operations

## Phase 2: Feature Development & Enhancement (Short-term)
### Messaging System Enhancement (2025-08-29)
**✅ COMPLETED: Dashboard Page Integration**
- ✅ Moved messaging from modal-based interface to dedicated dashboard page (`/dashboard/messages`)
- ✅ Created new route and controller endpoint following existing patterns (`/dashboard/wallet`, `/dashboard/user`)
- ✅ Implemented full-page messaging interface with better UX and more screen real estate
- ✅ Added proper navigation integration in dashboard sidebar with active state highlighting
**✅ COMPLETED: UI/UX Enhancement**
- ✅ Enhanced messaging UI design to match existing dashboard components (wallet, cart, modals)
- ✅ Implemented modern conversation interface with:
- ✅ Message bubbles with proper sender/recipient styling
- ✅ Timestamp formatting and message status indicators
- ✅ Real-time character count and input validation
- ✅ Loading states and empty state handling
- ✅ Toast notifications for success/error feedback (error only - success removed for cleaner UX)

- ✅ Restructured layout using flexbox with fixed header, scrollable messages, and anchored input
- ✅ Moved toast notifications from bottom-right to top-right to avoid blocking message input
- ✅ Removed success toast for message sending (message appearing in chat provides sufficient feedback)
- ✅ Added proper `gitea_enabled` configuration to dashboard controller context
**📋 PENDING: Advanced Features (Low Priority)**
- File attachment support and media preview
- Message search and filtering capabilities
- Message threading and reply functionality
- Typing indicators and read receipts
- Message reactions and emoji support
- Conversation archiving and organization
**Current Status**: Full-page messaging interface complete and production-ready with industry-standard UX. All core functionality implemented following marketplace design patterns and technical standards. Layout optimized for full-screen usage with proper message input visibility.
- **Slice statistics UI visualization**:
- Frontend: render cards/charts using returned fields; consider sparklines for utilization and trend charts for history when available.
- Add graceful empty state and loading skeletons.
- **Currency system enhancement**:
- TFC as base currency instead of USD (1 TFC = 1 USD display mapping).
- **Core marketplace workflow**:
- Farmer adds node → distributed into compute slices → appears in marketplace → purchasable → appears in orders.
## Phase 3: Advanced Features & Polish (Medium-term)
- **Farmer dashboard enhancements**:
- Align `updateNodeGroupSelects()` to the same normalization as `loadExistingGroups()` so `#nodeGroup` and `#nodeGroupSelect` include custom groups with consistent labels/counts.
- Extract a shared `normalizeGroups()` helper to centralize group_type handling (object|string), default/custom detection, and totals; reuse in both functions.
- Trigger select refresh after create/delete (call `updateNodeGroupSelects()` and `loadExistingGroups()` on success handlers).
- QA: Create/delete a custom group; verify Add Nodes and Edit Node modals refresh lists and labels; confirm counts.
- Improve empty/error states for group fetches (placeholder item on failure/empty; concise error logs).
- Sort groups alphabetically within Default and Custom sections.
- **API enhancements**:
- Review/extend `apiJson` for FormData and non-JSON/text endpoints if needed.
## Archived Work Plans (Historical Reference)
- Work plan: Group selects (2025-08-25 23:25 local)
- Step 1: Implement `normalizeGroups()` in `src/static/js/dashboard-farmer.js` (handles object|string `group_type`, default/custom detection, totals, labels).
- Step 2: Refactor `updateNodeGroupSelects()` to use `normalizeGroups()`; populate `#nodeGroup` and `#nodeGroupSelect` with defaults then customs; preserve "Single (No Group)".
- Step 3: Wire post-actions to refresh selects after create/delete (call `updateNodeGroupSelects()` and `loadExistingGroups()` on success).
- Step 4: QA: create/delete custom group; verify both Add Nodes and Edit Node modals update lists, counts, labels; check no console errors.
- Step 5: Polish: empty/error states and alphabetical sort within sections.
- Acceptance criteria:
- Custom groups appear in `#existingGroup`, `#nodeGroup`, and `#nodeGroupSelect` with "(Custom)" label and node counts where available.
- Default groups listed before custom groups; each section sorted alphabetically.
- Selects refresh automatically after create/delete without page reload.
- No direct `fetch(` or legacy `success` checks in the touched code paths; only `apiJson` with thrown errors.
- Work plan: API migrations (2025-08-25 23:26 local)
- Step 1: Migrated `src/static/js/dashboard-service-provider.js` to `apiJson`; remove `result.success`/`data.success` checks; centralize error toasts.
- Step 2: Migrated `src/static/js/dashboard_pools.js` and `src/static/js/dashboard-app-provider.js` (2025-08-27 local), plus `src/static/js/dashboard-user.js`, `src/static/js/marketplace-integration.js`, `src/static/js/marketplace_dashboard.js`, and `src/static/js/services.js` (2025-08-27 local) to `apiJson`.
- Step 3: Audit templates under `src/views/**` for inline `fetch` and swap to `apiJson` via a small injected helper or module import.
- Step 4: Add minimal shared error handler (utility) to standardize toast messages and 402 handling remains in interceptor.
- Acceptance criteria:
- No remaining `fetch(` calls in migrated files; all use `apiJson`.
- No boolean success flag checks; errors are thrown and surfaced to UI.
- 402 flows open the credit modal automatically via the global interceptor.
- Status (2025-08-27 local):
- **COMPLETED**: All JavaScript migration work finished successfully.
- API migrations Step 1 completed: `src/static/js/dashboard-service-provider.js` migrated to `apiJson`.
- API migrations Step 2 completed: `src/static/js/dashboard_pools.js` and `src/static/js/dashboard-app-provider.js` migrated.
- Additional migrations completed: `src/static/js/dashboard-user.js`, `src/static/js/marketplace-integration.js`, `src/static/js/marketplace_dashboard.js`, and `src/static/js/services.js`.
- Completed remaining JSON `fetch` migrations: `src/static/js/marketplace-compute.js`, `src/static/js/dashboard.js`, and `src/static/js/dashboard_layout.js` now use `apiJson`.
- **COMPLETED**: All inline scripts under `src/views/**` migrated to external JS files with `apiJson` integration.
- **COMPLETED**: Created 7 new external JS files with consistent error handling and CSP compliance.
- **COMPLETED**: Updated 8 HTML templates to remove all inline scripts and reference external JS files.
- **MILESTONE**: Zero remaining inline scripts or direct fetch calls in HTML templates across the entire codebase.
- QA plan: Farmer dashboard node groups (2025-08-25 23:26 local)
- Create custom group → appears in `#existingGroup`, `#nodeGroup`, `#nodeGroupSelect` with label/counts.
- Delete custom group → removed from all selects; affected nodes default to “Single (No Group)”.
- Assign node to custom group in Edit modal → persists and reflects in table and selects.
- Add nodes with selected group → nodes show in that group after add; counts update.
- Manage group view → opens and shows stats; no 404s; client-side selection continues to work.
- Error paths: simulate API failure; placeholder items render and no JS exceptions.
- Audit remaining parts of `src/static/js/dashboard-farmer.js` post-migration (modal state reset for View Details, Sync with Grid UX feedback, residual direct fetches if any).
- Add a small shared error handler utility to standardize toast messages; keep HTTP 402 handling in the global interceptor.
- Smoke/UX tests: navbar balance/cart count, add-to-cart, rent/purchase flows after recent apiJson migrations.
- Farmer Dashboard UX polish:
- Add loading states/spinners to group modals and node details fetch.
- Consider adding backend `GET /api/dashboard/node-groups/{id}` for direct access (optional; current client-side selection works).
- Improve error toasts with more context (group id, node id).
- Audit inline scripts under `src/views/**` and migrate to `apiJson` via an injected helper/module (ensure CSP compliance).
## Node Addition Reliability & JSON Persistence Hardening
- Deprecate legacy endpoint and handler
- Disable/remove route `POST /api/dashboard/add-nodes-automatic` in `src/routes/mod.rs` (legacy flow).
- Keep only `POST /api/dashboard/grid-nodes/add` → `DashboardController::add_grid_nodes`.
- If needed, hide behind a feature flag for quick rollback.
- Frontend duplication prevention
- In `src/static/js/dashboard-farmer.js`:
- No-op or remove `addValidatedNodes()` (legacy) and any bindings to it.
- Ensure only new handlers are attached: `validateGridNodes`, `addGridNodes`.
- Keep dataset flags in `initializeAddNodeForm()` to prevent duplicate listener attachment.
- Disable Add/Validate buttons during in-flight calls and re-enable on completion.
- Batch saves in FarmerService
- In `src/services/farmer.rs`, for multi-node add methods:
- `add_multiple_grid_nodes()`
- `add_multiple_grid_nodes_with_config()`
- `add_multiple_grid_nodes_with_comprehensive_config()`
- `add_multiple_grid_nodes_with_individual_pricing()`
- Accumulate node additions in memory and perform a single `UserPersistence::save_user_data(...)` after all nodes are appended to reduce write contention.
- Status: DONE (2025-08-23). Implemented single save after accumulation for multi-node paths.
- Per-user write serialization
- Introduce a per-user async lock (e.g., `tokio::sync::Mutex`) keyed by `user_email` (global registry using `once_cell` + `DashMap`/`Mutex`).
- Wrap load → modify → save sequences so only one write path per user runs at a time.
- Implement in persistence or a small write coordinator used by FarmerService and similar writers.
- Status: DONE (2025-08-23). Using global per-user async lock in `UserPersistence` and controller-level lock in `add_grid_nodes()`. Added `*_locked` persistence wrappers.
- Structured logging
- Add entry/exit logs and request IDs for `DashboardController::add_grid_nodes()` in `src/controllers/dashboard.rs`.
- Add logs around `load_user_data`/`save_user_data` in `src/services/user_persistence.rs` including user email, operation, and timing.
- Status: DONE (2025-08-23). Includes lock wait durations and total elapsed timings.
- Ops & remediation
- Keep `scripts/fix_user_data.py` documented as a repair tool, but aim for it to be unnecessary post-fix.
## What shipped in this pass (2025-08-23)
- Frontend
- `dashboard-farmer.js`: wiring continued to prefer new add flow and guard against duplicate submits.
- Backend
- Structured logging + timings with `req_id` in `add_grid_nodes()`; lock wait metrics under `concurrency` target.
- Persistence timing instrumentation; added `load_user_data_locked`/`save_user_data_locked` wrappers.
- FarmerService: multi-node add paths batch-save once.
- WalletController: replaced all direct persistence calls with `*_locked` and propagated `req_id`; fixed remaining async call sites and added await.
- PoolController: updated to call `WalletController::load_user_with_session_data(.., req_id).await` in handlers.
- General cleanup: consistent ID parsing and option handling in relevant areas.
## Build status (cargo check 2025-08-23 14:27 local)
- Result: cargo check passed (no errors). Binary built with warnings.
- Warnings: 346 (212 duplicates). Continue staged cleanup.
- Note: Structured logs now available under targets `api.dashboard`, `user_persistence`, and `concurrency`.
## Build status (cargo check 2025-08-25 15:26 local)
- Result: cargo check passed (no errors). Binary built with warnings.
- Warnings: 345 (210 duplicates). Continue cleanup, especially dead code in `slice_calculator.rs`, `slice_rental.rs`, `ssh_key_service.rs`, and `user_persistence.rs` noted by compiler.
- Note: JS changes (apiJson migrations) do not affect Rust build; proceed to warning cleanup after UI fixes.
## Next steps
- Warning cleanup across the codebase (prefix unused vars with `_` or remove; tighten imports).
- Audit persistence call sites and switch to `*_locked` wrappers where no outer controller lock exists:
- Prioritize: `src/services/session_manager.rs`, `src/services/ssh_key_service.rs`, and `src/controllers/pool.rs` persistence paths.
- Propagate `req_id` into `SessionManager` and `SSHKeyService`; audit controllers that call them to pass/await.
- Tests & manual verification:
- Concurrency test: two simultaneous add requests for the same user; expect serialized writes and correct persistence.
- Concurrency test: concurrent wallet transfers to same user; ensure per-user lock serialization and no corruption.
- Smoke test pool exchange/stake flows after we migrate pool persistence to `*_locked`.
- Smoke tests for navbar/cart/SSH keys after `apiJson` refactors.
- Documentation:
- Ensure references use `POST /api/dashboard/grid-nodes/add` (deprecated legacy endpoint removed/hidden).
## Learnings (2025-08-23)
- The E0061/E0308 errors were from outdated call sites after making helper methods async and adding `req_id`. Fixes required passing `req_id` and adding `.await` consistently.
- Keep a single locking discipline: use `UserPersistence::*_locked` for per-user JSON updates and avoid layering another lock around them.
- Generate `req_id` at handler boundaries and propagate into all persistence/service calls for traceable logs and timings.
- Stagger refactors module-by-module and run `cargo check` frequently to catch signature drifts early (especially in controllers consuming services).
## Details
### apiJson
- `window.apiJson` helper (`src/static/js/base.js`).
- Adoption status:
- `src/static/js/checkout.js` uses `apiJson` for `POST /api/orders`.
- `src/static/js/base.js` navbar and cart loaders now use `apiJson`.
- `src/static/js/dashboard-ssh-keys.js` fully migrated to `apiJson`.
- `src/static/js/dashboard-service-provider.js` fully migrated to `apiJson` (invoice downloads continue to use `fetch` for binary/text).
- `src/static/js/dashboard_pools.js` fully migrated to `apiJson` (GETs set `cache: 'no-store'`; toasts standardized; HTTP 402 handled by interceptor).
- `src/static/js/dashboard-app-provider.js` fully migrated to `apiJson` (GETs set `cache: 'no-store'` for dashboard/app list/deployment details; toasts standardized; HTTP 402 handled by interceptor).
- `src/static/js/dashboard-user.js` fully migrated to `apiJson`.
- `src/static/js/marketplace-integration.js` fully migrated to `apiJson`.
- `src/static/js/marketplace_dashboard.js` fully migrated to `apiJson`.
- `src/static/js/services.js` fully migrated to `apiJson`.
- `src/static/js/dashboard_wallet.js` uses `apiJson` for wallet endpoints.
- `src/static/js/marketplace-compute.js` fully migrated to `apiJson` (rent, purchase, add-to-cart; 402 handled by interceptor; 401 triggers auth modal).
- `src/static/js/dashboard.js` uses `apiJson` for navbar dropdown balance.
- `src/static/js/dashboard_layout.js` uses `apiJson` for dashboard cart count.
- Audit targets for migration (`fetch` → `apiJson`):
- Inline scripts under `src/views/**`.
## UI Progress (2025-08-25 15:26 local)
- Add Nodes: Works via the new flow (`POST /api/dashboard/grid-nodes/add`). Form resets and UI refresh triggers are in place; good progress.
- Delete Node: Works. Clicking Delete removes the node and the UI updates accordingly.
- View Details (Slice table action): Fixed stale/wrong data via abort + sequence guard and `no-store` caching; modal is rebuilt per open.
- Slice Statistics: Works. Endpoint `/api/dashboard/farmer/slice-statistics` returns stats and UI updates the counters.
- Refresh Calculations: Works (confirmed via notification and page reload).
- Sync with Grid: Shows immediate 'Syncing...' toast, then success; backend takes time, UX now communicates progress.
- Note: Re-test node group operations end-to-end after `apiJson` migration in `dashboard-farmer.js` (list/create/delete/assign). Monitor console/network for envelope-free responses and interceptor behavior.
## Next TODO: Farmer Dashboard UX Fixes (2025-08-25 22:35 local)
- Create Custom Group: Fixed (rely on data attributes only).
- Manage (Node Group): Fixed (load list and select by id client-side).
- Slice Management:
- Refresh Calculations: Works (✅). Leave as-is.
- Sync with Grid: Consider adding a subtle spinner on the button while in-flight (optional; toasts already added).
- Slice table Actions (View Details): Fixed; nodeId binding works and race/stale cases guarded.
- Capacity Analytics: No data or graphs are displayed.
- Earnings Monitoring: No data or graphs are displayed.
Notes:
- Verify button handlers and modal initialization in `src/static/js/dashboard-farmer.js`.
- Confirm API paths for refresh/sync actions match backend routes in `src/routes/mod.rs` (`/api/dashboard/refresh-slice-calculations`, `/api/dashboard/sync-with-grid`).
- Inspect console for errors and ensure `window.apiJson` calls resolve and update UI accordingly.
## ✅ RESOLVED: Messaging Interface Integration (2025-08-29)
### Problem Summary
The "Contact Provider" flow for service bookings had two critical issues:
1. Thread creation failing with 400 Bad Request due to missing Content-Type header
2. New threads not being auto-selected after creation due to incorrect matching logic
### Final Status - ALL ISSUES RESOLVED
- **Thread matching logic**: ✅ WORKING - correctly identifies no existing thread for new booking ID
- **New thread creation**: ✅ FIXED - Added missing Content-Type header to POST `/api/messages/threads`
- **Thread auto-selection**: ✅ FIXED - Updated matching logic to use both recipient_email AND context_id
- **Enhanced logging**: ✅ ADDED - both frontend and backend logging in place
### Technical Details
**Frontend (dashboard-messages.js):**
- URL parameter handling works correctly
- Thread search logic properly matches by `recipient_email` and `context_id` (booking ID)
- ✅ FIXED: Added missing `Content-Type: application/json` header to thread creation request
- Using correct endpoint: `/api/messages/threads` (not `/api/messages`)
**Backend (messaging.rs):**
- Added validation logging for `CreateThreadRequest`
- Validates: `recipient_email`, `context_type`, `subject` not empty
- Route registration confirmed correct in `src/routes/mod.rs` line 239
**API Structure:**
```rust
// Expected by /api/messages/threads
pub struct CreateThreadRequest {
pub recipient_email: String,
pub context_type: String,
pub context_id: Option<String>,
pub subject: String,
}
```
**Frontend Request Data:**
```javascript
{
recipient_email: "user0@example.com",
context_type: "service_booking",
context_id: "req-104ecd70-1699cf5a",
subject: "Service Booking #req-104ecd70-1699cf5a"
}
```
### Resolution Summary
**Root Cause:** Missing `Content-Type: application/json` header in frontend thread creation request caused server to return 400 Bad Request due to JSON deserialization failure.
**Fixes Applied:**
1. **Thread Creation Fix** - Added proper Content-Type header:
```javascript
const response = await apiJson('/api/messages/threads', {
method: 'POST',
headers: {
'Content-Type': 'application/json' // ← Added this
},
body: JSON.stringify(requestData)
});
```
2. **Thread Auto-Selection Fix** - Updated matching logic:
```javascript
// OLD: Only matched by recipient (selected wrong thread)
const newThread = this.threads.find(thread =>
thread.recipient_email === recipient
);
// NEW: Match by both recipient AND context_id (selects correct thread)
const newThread = this.threads.find(thread =>
thread.recipient_email === recipient &&
thread.context_id === bookingId
);
```
### Files Modified
- ✅ `src/static/js/dashboard-messages.js` - Added Content-Type header + fixed thread selection logic
- `src/controllers/messaging.rs` - Enhanced validation logging (already in place)
- `src/static/js/dashboard-user.js` - Contact Provider redirect (already working)
### Verified Working Flow
When clicking "Contact Provider" for a service booking:
1. ✅ Redirect to `/dashboard/messages` with URL parameters
2. ✅ Find no existing thread for booking ID
3. ✅ Create new thread via POST `/api/messages/threads` (FIXED - Content-Type header)
4. ✅ Reload conversations and auto-select new thread (FIXED - matching logic)
5. ✅ Display conversation interface ready for messaging
**Status: FULLY RESOLVED** - Contact Provider flow works end-to-end with proper thread auto-selection

# Data Validation Guide
## Overview
This guide documents the data validation tools and processes for the Project Mycelium application. These tools help maintain data integrity and resolve JSON parsing errors when user data schemas evolve.
## Problem Context
The application stores user data in JSON files that must match Rust struct definitions for serde deserialization. When schemas change or data becomes corrupted, parsing errors occur that prevent users from accessing dashboard features.
## Validation Tools
### 1. Rust Data Validator (`src/utils/data_validator.rs`)
A comprehensive validation utility that:
- Validates JSON structure against expected Rust schemas
- Provides detailed error reporting with line numbers
- Handles schema migration and repair
- Supports batch validation of multiple user files
**Usage:**
```rust
use crate::utils::data_validator::DataValidator;
let validator = DataValidator::new();
let result = validator.validate_user_file("user_data/user1_at_example_com.json");
```
### 2. Python Validation Script (`fix_user_data.py`)
A standalone Python script that:
- Fixes common schema mismatches automatically
- Handles missing fields, invalid enum variants, and null values
- Processes all user data files in batch
- Provides detailed change reporting
**Usage:**
```bash
cd projectmycelium
python3 scripts/fix_user_data.py
```
## Common Schema Issues and Solutions
### Missing Fields
**Problem:** JSON missing required fields like `minimum_deployment_duration`, `preferred_regions`
**Solution:** Add default values based on field type and context
### Invalid Enum Variants
**Problem:** Old enum values like `ServiceProgress`, `AppDeployment`
**Solution:** Map to current valid variants: `ServiceCreated`, `Deployment`
### Incorrect Object Structure
**Problem:** Objects not matching expected struct definitions
**Solution:** Restructure to match current schema requirements
### Example: UsageStatistics Structure
```json
{
"usage_statistics": {
"total_deployments": 85,
"active_services": 12,
"total_spent": "2450.25",
"favorite_categories": ["compute", "storage", "networking"],
"usage_trends": [
{
"period": "month",
"metric": "deployments",
"value": 25.5,
"change_percentage": 12.3
}
],
"login_frequency": 4.2,
"preferred_regions": ["us-east", "eu-west"],
"account_age_days": 150,
"last_activity": "2025-06-18T20:30:00Z"
}
}
```
## Troubleshooting Process
### 1. Identify Parsing Errors
Look for serde deserialization errors in application logs:
```
Failed to parse user data for user@example.com: missing field `field_name` at line X column Y
```
### 2. Run Validation Tools
Use the Python script for quick fixes:
```bash
python3 scripts/fix_user_data.py
```
Or use the Rust validator for detailed analysis:
```rust
let validator = DataValidator::new();
validator.validate_all_user_files();
```
### 3. Manual Schema Updates
For complex schema changes, manually update JSON structure to match current Rust struct definitions in `src/models/user.rs`.
### 4. Verify Resolution
Test the application to ensure parsing errors are resolved:
```bash
cargo run
```
## Best Practices
### Schema Evolution
1. **Update validation tools** when adding new required fields to Rust structs
2. **Provide migration logic** for existing data
3. **Test with all user data files** before deploying schema changes
4. **Document breaking changes** in this guide
### Data Integrity
1. **Run validation regularly** as part of development workflow
2. **Backup user data** before applying automated fixes
3. **Validate after manual edits** to ensure correctness
4. **Monitor application logs** for new parsing errors
### Tool Maintenance
1. **Keep validation tools updated** with current schema requirements
2. **Add new validation rules** for new data structures
3. **Test validation tools** with various error scenarios
4. **Document new validation patterns** in this guide
## File Locations
- **Rust Validator:** `src/utils/data_validator.rs`
- **Python Script:** `scripts/fix_user_data.py`
- **User Data:** `user_data/*.json`
- **Schema Definitions:** `src/models/user.rs`
- **Utils Module:** `src/utils/mod.rs`
## Integration
The validation tools are integrated into the utils module and can be used throughout the application for:
- Development-time validation
- Runtime error recovery
- Data migration during updates
- Quality assurance testing
## Future Enhancements
Consider adding:
- Automated validation in CI/CD pipeline
- Real-time validation during data updates
- Schema versioning and automatic migration
- Web interface for data validation and repair

# Quick Troubleshooting: JSON Parsing Errors
## 🚨 Emergency Fix
If you see JSON parsing errors in logs, run this immediately:
```bash
cd projectmycelium
python3 scripts/fix_user_data.py
cargo run
```
## Common Error Patterns
### Missing Field Errors
```
missing field `field_name` at line X column Y
```
**Quick Fix:** Run `python3 scripts/fix_user_data.py` - it handles most missing fields automatically.
### Invalid Enum Variant
```
unknown variant `OldVariantName`
```
**Quick Fix:** The Python script maps old variants to new ones automatically.
### Structure Mismatch
```
invalid type: map, expected a sequence
```
**Manual Fix Required:** Check the data structure against `src/models/user.rs` definitions.
## Step-by-Step Resolution
1. **Stop the application** if it's running
2. **Run the fix script:**
```bash
python3 scripts/fix_user_data.py
```
3. **Check the output** for what was fixed
4. **Test the application:**
```bash
cargo run
```
5. **If errors persist,** check the detailed guide: [`data-validation-guide.md`](./data-validation-guide.md)
## Prevention
- Run `python3 scripts/fix_user_data.py` after pulling schema changes
- Monitor application logs for new parsing errors
- Backup user data before making manual edits
## Need Help?
1. Check [`data-validation-guide.md`](./data-validation-guide.md) for detailed information
2. Look at `src/models/user.rs` for current schema requirements
3. Use the Rust validator in `src/utils/data_validator.rs` for detailed analysis

# Project Mycelium
## Overview
- The Project Mycelium follows devops procedures and open-source + Agile philosophy
- For devs, we must develop and code until the Project Mycelium is production-ready and can be run by an ops team (1+ person) to deploy and maintain the marketplace
- In practical sense, once tested by users online, we gather feedback and create issues and then PRs to fix them (as in problem+solution forward & dynamic solution approach).
- By design, we present a clear roadmap and phases, such as internal, external and public testings
Last updated: 2025-08-12
## Phases by Outcome
- Alpha (UI only, local/git persistence)
- DoD: user can browse, add to cart; no backend calls; basic UX validated
- Beta (PostgREST + Stripe integrated)
- DoD: end-to-end test purchase on dev succeeds; errors logged; basic monitoring
- GA (HA on Kubernetes on ThreeFold Grid)
- DoD: self-healing deployment; no single point of failure; metrics + alerts; backup/restore tested

2. Push changes to `development` branch in gitea
3. Run `make update-dev` to deploy to development environment
### Production Workflow
1. Create PR from `development` to `main` in gitea
2. Review and merge the PR
3. Run `make update-prod` to deploy to production environment
## Server Configuration
The deployment assumes the following server setup:
- **Development Repository Path**: `/root/code/git.ourworld.tf/tfgrid_research/dev/projectmycelium`
- **Production Repository Path**: `/root/code/git.ourworld.tf/tfgrid_research/prod/projectmycelium`
- **Development Service**: `tf-marketplace-dev`
- **Production Service**: `tf-marketplace-prod`
- **Zinit Configuration**: Service configs stored in `/etc/zinit/`
- **Deployment Scripts**: Stored in `/etc/zinit/cmds/`
## Troubleshooting
### SSH Connection Issues
Ensure you have SSH key access to `root@info.ourworld.tf`:
```bash
ssh root@info.ourworld.tf 'echo "Connection successful"'
```
### Service Not Starting
Check service logs:
```bash
make logs
```
Or check directly on the server:
```bash
ssh root@info.ourworld.tf 'zinit log tf-marketplace-prod'
ssh root@info.ourworld.tf 'zinit log tf-marketplace-dev'
```
### Missing .env.deploy File
If you see errors about missing `.env.deploy` file:
1. Copy the template: `cp .env.deploy.example .env.deploy`
2. Edit the file with your Gitea credentials
3. Ensure `GITEA_USER` and `GITEA_TOKEN` are properly set
### Invalid Gitea Credentials
If setup fails due to invalid credentials:
1. Verify your Gitea username and personal access token
2. Ensure the token has appropriate repository access permissions
3. Update `.env.deploy` with correct credentials
### Service Status Issues
Check service status:
```bash
make status
```
This will show if services are running, stopped, or have errors.
## Manual Deployment
If you need to deploy manually, the commands are:
### Development
```bash
ssh root@info.ourworld.tf 'cd /root/code/git.ourworld.tf/tfgrid_research/dev/projectmycelium && git checkout development && git pull && zinit restart tf-marketplace-dev'
```
### Production
```bash
ssh root@info.ourworld.tf 'cd /root/code/git.ourworld.tf/tfgrid_research/prod/projectmycelium && git checkout main && git pull && zinit restart tf-marketplace-prod'
```
## Environment Files
### .env.deploy
Required for deployment setup. Contains Gitea credentials:
```bash
GITEA_USER=your_username
GITEA_TOKEN=your_personal_access_token
```
### .env (Local Development)
Generated automatically by `make build` or `make key`. Contains:
- `SECRET_KEY` - Auto-generated secure key
- Other application configuration variables
## Service Management
The deployment uses zinit for service management:
- **Development Service**: `tf-marketplace-dev`
- **Production Service**: `tf-marketplace-prod`
- **Configuration Files**:
- `/etc/zinit/tf-marketplace-dev.yaml`
- `/etc/zinit/tf-marketplace-prod.yaml`

# Basic Deployment Guide for Project Mycelium
This guide provides a simplified approach to deploying the Project Mycelium on a server, using `cargo run` directly.
> **🚀 For automated deployment, see [Automated Deployment Guide](./automated-deployment.md)**
We show the steps for the main branch, for development branch, simply add _dev, -dev accordingly and checkout into development.
## Prerequisites
- Linux server with:
- Git installed
- Rust toolchain installed
- Caddy web server installed
- zinit service manager installed
- Root or access
## Step 1: Clone the Repository
We'll clone the repository to a structured directory path:
```bash
# Create directory structure
mkdir -p /root/code/git.ourworld.tf/tfgrid_research/
cd /root/code/git.ourworld.tf/tfgrid_research/
# Clone the repository
git clone https://git.ourworld.tf/tfgrid_research/projectmycelium
cd projectmycelium
git checkout main
```
## Step 2: Create a zinit Service
Create a zinit service to run and manage the application:
1. First create the service script:
```bash
mkdir -p /etc/zinit/cmds
nano /etc/zinit/cmds/tf-marketplace.sh
```
Add the following content:
```bash
#!/bin/bash
cd /root/code/git.ourworld.tf/tfgrid_research/projectmycelium
git checkout main
exec /root/.cargo/bin/cargo run --release --bin projectmycelium -- --port 9999
```
Make the script executable:
```bash
chmod +x /etc/zinit/cmds/tf-marketplace.sh
```
2. Create the zinit service definition:
```bash
nano /etc/zinit/tf-marketplace.yaml
```
Add the following content:
```yaml
exec: "/bin/bash -c /etc/zinit/cmds/tf-marketplace.sh"
```
## Step 3: Configure Caddy
Create or update your Caddyfile to serve the application:
```bash
# Edit the Caddyfile
nano /root/code/github/despiegk/env_web/ourworld/ovh1_web_current/caddy/Caddyfile
```
- Add the Caddy file in Caddyfile
```
import threefold_marketplace.caddy
```
- Create `threefold_marketplace.caddy` then enter the following. Adjust your domain as needed.
```
threefold.pro {
reverse_proxy localhost:9999 {
header_up Host {host}
header_up X-Real-IP {remote}
header_up X-Forwarded-Proto {scheme}
}
}
```
## Step 4: Start Services with zinit
- Monitor the zinit service
```
zinit monitor tf-marketplace-prod
```
- Start the service
```bash
# Start the marketplace service
zinit start tf-marketplace-prod
# Restart Caddy to load new configuration
zinit restart caddy
```
## Automated Deployment with Makefile
For easier deployment, you can use the provided Makefile targets with separate dev and prod environments:
### First-Time Setup
1. **Set up deployment credentials:**
```bash
# Create deployment credentials file
cp .env.deploy.example .env.deploy
# Edit deployment credentials
nano .env.deploy
# Add your Gitea credentials:
GITEA_USER=your_username
GITEA_TOKEN=your_personal_access_token
```
2. **Deploy to server (choose one):**
**Option A: Setup development only:**
```bash
make setup-dev
```
**Option B: Setup production only:**
```bash
make setup-prod
```
**Option C: Setup both dev and prod:**
```bash
make setup
```
### Clean Environment Structure
The deployment system uses industry-standard environment separation:
```
/root/code/git.ourworld.tf/tfgrid_research/
├── dev/projectmycelium/ # Development branch (port 9998)
└── prod/projectmycelium/ # Production branch (port 9999)
```
**Benefits:**
- ✅ **No build conflicts**: Each environment has its own build cache
- ✅ **Independent deployments**: Dev and prod can be updated separately
- ✅ **Parallel compilation**: Both can build simultaneously
- ✅ **Clean separation**: Different branches, ports, and domains
### What each setup does:
**setup-dev:**
- Sets up development environment only
- Clones to `dev/projectmycelium/`
- Uses development branch
- Runs on port 9998 (dev.threefold.pro)
**setup-prod:**
- Sets up production environment only
- Clones to `prod/projectmycelium/`
- Uses main branch
- Runs on port 9999 (threefold.pro)
- Restarts Caddy for production
**setup (both):**
- Runs both dev and prod setups
- Complete environment setup
### Regular Deployments
**Simple Updates (recommended):**
```bash
# Update development branch (just git pull + restart)
make update-dev
# Update production branch (just git pull + restart)
make update-prod
```
**What happens:**
- SSH to server
- Navigate to repository directory
- Git pull latest changes
- Restart the service
**Monitoring:**
```bash
# Check service status
make status
# View service logs
make logs
# Get help with all commands
make help
```
**Manual Alternative:**
```bash
# Development
ssh root@info.ourworld.tf
cd /root/code/git.ourworld.tf/tfgrid_research/dev/projectmycelium
git checkout development && git pull
zinit restart tf-marketplace-dev
# Production
ssh root@info.ourworld.tf
cd /root/code/git.ourworld.tf/tfgrid_research/prod/projectmycelium
git checkout main && git pull
zinit restart tf-marketplace-prod
```
### Creating a Gitea Personal Access Token
1. Go to https://git.ourworld.tf/user/settings/applications
2. Click "Generate New Token"
3. Give it a descriptive name (e.g., "Project Mycelium Deployment")
4. Select minimal permissions: **repository read access only**
5. Copy the generated token and add it to your local `.env` file as `GITEA_TOKEN`
### Environment File Structure
**Two separate environment files for clean separation:**
**Local `.env.deploy` (deployment credentials only):**
```bash
# Gitea credentials for deployment
GITEA_USER=your_username
GITEA_TOKEN=your_personal_access_token
```
**Server `.env` (application secrets, auto-generated):**
```bash
# Application secret (automatically generated on server)
SECRET_KEY=auto_generated_secret_key
```
**Clean Separation:**
- **Deployment credentials**: Only in `.env.deploy`, used for git authentication
- **Application secrets**: Generated automatically on server in cloned repo
- **No mixing**: Deployment and application concerns completely separated
## Updating the Application
To update the application after making changes:
```bash
# Go to the repository directory
cd /root/code/git.ourworld.tf/tfgrid_research/projectmycelium
# Pull the latest changes
git checkout main
git pull
# Restart the application service
zinit restart tf-marketplace-prod
```
## Monitoring the Application
You can monitor the application status with these commands:
```bash
# Check if the application is running
zinit list
# View application logs
zinit log tf-marketplace-prod
# Monitor logs in real-time
tail -f /var/log/zinit/tf-marketplace-prod.log
```
## Troubleshooting
### Application Not Starting
Check for errors in the application logs:
```bash
zinit log tf-marketplace-prod
```
### Connection Refused
Make sure the application is running and listening on the correct port:
```bash
ss -tuln | grep 9999
```

# Project Mycelium Ops Method
## Introduction
We present simple CLI tools to deploy the Project Mycelium.
## Tools
You can use quick utility tools gits from ucli and pal from scottyeager (see https://github.com/ucli-tools, https://github.com/scottyeager/pal)
- When any step is confirmed to work, save as version management control
```
git add . && pal /commit --yolo && git push
```
- To push as a PR when many commits create a whole step/task in the roadmap/todo
```
gits pr create --title 'Update' --base development && gits pr merge --pr-number $(gits pr-latest)
```
- To update the website from e.g. development using Makefile
```
make update-dev
```
- This will ssh into the server hosting the marketplace on dev and prod (dev.threefold.pro, threefold.pro)
## Prerequisites
- git, make
- Docker or Podman (if containerizing locally)
- SSH access to deployment hosts (dev/prod)
- kubectl/helm if deploying to Kubernetes
- Config/secrets available (Stripe keys, PostgREST endpoint, DB credentials)
## Environments
- Dev: dev.threefold.pro
- Prod: threefold.pro
## Configuration
- Environment variables (examples):
- STRIPE_SECRET_KEY, STRIPE_PUBLISHABLE_KEY
- POSTGREST_URL
- DATABASE_URL or connection parameters
- APP_ENV (development|production)
- Provide via .env files, system service env files, or Kubernetes Secrets as appropriate.
## Deployment Flows
- Local
- Build/run the app locally; verify basic UI and flows.
- Dev
- Use: `make update-dev` (as provided above)
- Verify deployment (see Verification)
- Prod
- Follow the same deployment pattern as dev against prod host or use corresponding prod target if defined.
## Verification
- Health: open the site on the target environment (dev.threefold.pro or threefold.pro)
- Basic smoke:
- Load homepage and key pages
- Add item to cart
- Run a test checkout with Stripe test keys (on dev)
## Rollback
- Identify last known good commit/tag
- Revert: `git revert <commit>` or checkout the tag/commit
- Redeploy using the same steps (e.g., `make update-dev`)
## Operations
- Logs: inspect application/server logs on target hosts; if running on Kubernetes, use `kubectl logs`
- Monitoring: confirm metrics/alerts if configured
- Backups: ensure regular DB and config backups and test restore procedures
## Troubleshooting
- Missing/incorrect env vars → verify configuration section
- SSH failures → validate keys and host reachability
- Stripe errors → confirm test vs live keys per environment
## Standard git equivalents
- Save work (equivalent to pal):
```
git add -A && git commit -m "<message>" && git push
```
- Create a PR: push your branch and open a PR on your Git hosting provider targeting `development` (or relevant branch)
## Checklists
- Pre-deploy: correct branch, env config present, backup taken (if needed)
- Post-deploy: site loads, smoke tests pass, logs clean of new errors
## References
- Dev design method: `../../../dev/method/current/design_method.md`
- DevOps overview: `../../../devops.md`
- Architecture & Roadmap: `../../../dev/design/current/projectmycelium-roadmap.md`
