-## 1. Architecture Vision (Target State)
+## 2. Error Debugging Methodology
 
-### Core Design Principles
+### **Proven Systematic Methodology Excellence:**
 
-#### **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
+The systematic approach established in previous phases continued exceptional effectiveness:
 
-#### **ResponseBuilder Envelope & Frontend Contract**
-```json
-{
-  "success": true|false,
-  "data": { ... },
-  "error"?: { ... }
+```bash
+# Error tracking pipeline (proven highly effective)
+cargo check 2>&1 | grep "error\[" | wc -l                    # Progress monitoring
+cargo check 2>&1 | grep "error\[" | sort | uniq -c | sort -nr # Pattern analysis
+```
+
+**Execution Strategy Validated:**
+1. **Progress Tracking**: Regular error count measurements for monitoring reduction
+2. **Pattern Analysis**: Target highest-count error categories for maximum impact
+3. **Systematic Fixes**: Apply multiple related fixes in single operations
+4. **Type Safety**: Maintain architectural integrity throughout
+5. **Builder Consistency**: Unified patterns across codebase
+

+```rust
+// Core data structure (implemented)
+struct SSHKey {
+    id: String,
+    name: String,
+    public_key: String,
+    key_type: SSHKeyType,
+    fingerprint: String,
+    is_default: bool,
+    created_at: DateTime<Utc>,
 }
-```
-- 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,
+// Validation and management (implemented)
+struct SSHKeyService {
+    // Validation, fingerprint generation, format checking
+    // Integration with UserPersistentData
 }
 ```
 
-#### **ResponseBuilder Pattern**
-```rust
-ResponseBuilder::success()
-    .data(json!({ "products": products }))
-    .build()
+**Summary:** SSH Key Management system is **FULLY OPERATIONAL** with all 4 core operations working perfectly. Ready for VM/cluster deployment integration and UX testing framework.
+

 ```
 
----
+**Key Architectural Components:**
 
-## 3. Immediate Development Priorities
+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
 
-### **A. Runtime Testing & Validation (Week 1)**
-1. **Critical User Flows**

-## 4. Development Guidelines for AI Coders
+## 5. UX Testing Framework Development (Section 13 Implementation - 2025-08-22)
 
-### **Code Organization**
-- **Controllers**: [`src/controllers/`](src/controllers/) - HTTP request handling with ResponseBuilder
-- **Services**: [`src/services/`](src/services/) - Business logic and data operations
-- **Models**: [`src/models/`](src/models/) - Data structures and builders
-- **Utils**: [`src/utils/`](src/utils/) - Shared utilities and helpers
+##### Checkout & Orders Contract — Implemented 2025-08-23
 
-### **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)
+- **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=...]`.
 
-### **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
+- **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.
 
-### **Configuration Management**
-- **Environment-based** configuration via [`ConfigurationBuilder`](src/config/builder.rs)
-- **Feature flags** for dev/prod differences
-- **Database connection** management
-- **External service** integration settings
+###### 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.
 
-## 5. Success Criteria
+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.

-## 6. Architecture Decision Records
+### **Technical Breakthrough: SSH Key Template Pattern**
 
-### **Data Architecture**
-- **Decision**: Persistent file-based user data storage
-- **Rationale**: Simplicity, portability, and direct user ownership
-- **Implementation**: [`UserPersistence`](src/services/user_persistence.rs) service layer
+#### **What Works (Proven Pattern)**
+```rust
+// Direct service instantiation with builder pattern
+let ssh_service = SSHKeyService::builder().build()?;
 
-### **Frontend Architecture**
-- **Decision**: CSP-compliant external JS with JSON hydration
-- **Rationale**: Security, maintainability, and separation of concerns
-- **Implementation**: [`src/static/js/`](src/static/js/) modules with data hydration
+// Persistent data operations (no session mocking)
+let user_data = UserPersistence::load_user_data(user_email).unwrap_or_default();
 
-### **API Design**
-- **Decision**: Consistent JSON envelope via [`ResponseBuilder`](src/utils/response_builder.rs)
-- **Rationale**: Predictable frontend integration and error handling
-- **Implementation**: All controllers use ResponseBuilder pattern
+// 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)?;
+```
 
-This roadmap provides the complete vision and current state for an AI coder to continue development. The foundation is solid with zero compilation errors, established architectural patterns, and clear next steps for feature completion and production readiness.
\ No newline at end of file
+#### **What Caused 89 Compilation Errors**

-
-#### **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]

-    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
