2. Error Debugging Methodology

Proven Systematic Methodology Excellence:

The systematic approach established in previous phases continued exceptional effectiveness:

# 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

Architecture & System Interaction Analysis

Frontend-Backend Data Flow:

graph TD
    A[HTML Template] --> B[JavaScript Event Handlers]
    B --> C[AJAX API Calls]
    C --> D[Rust Controller]
    D --> E[SSH Key Service]

    G --> F
    F --> E
    E --> D
    D --> H[ResponseBuilder]
    H --> C
    C --> I[DOM Updates]

Key Architectural Components:

1. HTML Template Layer (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)

   • 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)

   • 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)

   • 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
• 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.

Technical Breakthrough: SSH Key Template Pattern

What Works (Proven Pattern)

// 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
• 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/
• Module Configuration: tests/frontend_ux/mod.rs
• Test Runner: tests/frontend_ux/test_runner.rs
• Cargo Feature: Tests require --features="ux_testing" flag

Test Execution Pattern

# Individual test execution
cargo test --test public_access_ux --features="ux_testing"
