Implementation Plan Updates

Overview

Based on the comprehensive codebase review, the implementation plans have been enhanced with critical details addressing the 3 high-priority gaps identified in the review.

Date: November 2025 Status: ✅ Complete Files Modified:

• 03_IMPLEMENTATION_PLAN.md (Phase 3 enhanced)
• 03_IMPLEMENTATION_PLAN_PART2.md (Phase 9 enhanced)

---

1. Scenario Conversion to ERB (Phase 3)

What Was Added

Location: 03_IMPLEMENTATION_PLAN.md Section 3.2

Enhancement: Complete automation script for converting all 26 scenario files to ERB structure.

Details

Main Scenarios (Production):

1. ceo_exfil.json → app/assets/scenarios/ceo_exfil/scenario.json.erb
2. cybok_heist.json → app/assets/scenarios/cybok_heist/scenario.json.erb
3. biometric_breach.json → app/assets/scenarios/biometric_breach/scenario.json.erb

Test/Demo Scenarios (23 files):

• scenario1-4
• npc-hub-demo-ghost-protocol
• npc-patrol-lockpick
• test-multiroom-npc
• test-npc-face-player, patrol, personal-space, waypoints
• test-rfid, test-rfid-multiprotocol
• test_complex_multidirection, horizontal_layout, vertical_layout
• test_mixed_room_sizes, multiple_connections
• timed_messages_example
• title-screen-demo
• npc-sprite-test2

Implementation Approach

# Complete bash script provided in plan
# Handles all 26 files automatically
./scripts/convert-scenarios.sh

Key Features:

• ✅ Just renames .json → .erb (no content changes initially)
• ✅ Preserves git history with mv commands
• ✅ Creates proper directory structure
• ✅ Handles missing files gracefully
• ✅ Provides summary and verification
• ✅ Manual alternative for 3 main scenarios

ERB Randomization:

• Files renamed to .erb but keep JSON content
• Actual ERB code (<%= random_password %>) added later in Phase 4
• Allows immediate testing without randomization

---

2. CSRF Token Handling (Phase 9.3)

What Was Added

Location: 03_IMPLEMENTATION_PLAN_PART2.md Section 9.3 (NEW)

Enhancement: Complete CSRF token implementation for Rails security.

Why This Is Critical

Rails requires CSRF tokens for all POST/PUT/DELETE requests. Without proper token injection:

• ❌ All unlock requests fail with 422 status
• ❌ State sync fails
• ❌ Inventory updates fail
• ❌ Game becomes unplayable

Implementation Details

9.3.1 Server-Side Token Injection

File: app/views/break_escape/games/show.html.erb

<%= javascript_tag nonce: true do %>
  window.breakEscapeConfig = {
    gameId: <%= @game.id %>,
    apiBasePath: '<%= break_escape_path %>/games/<%= @game.id %>',
    assetsPath: '/break_escape/assets',
    csrfToken: '<%= form_authenticity_token %>',  // 🔑 CRITICAL
    missionName: '<%= j @game.mission.display_name %>',
    startRoom: '<%= j @game.scenario_data["startRoom"] %>',
    debug: <%= Rails.env.development? %>
  };
<% end %>

Key Points:

• Token injected via form_authenticity_token
• Loaded BEFORE game scripts
• Available as window.breakEscapeConfig.csrfToken

9.3.2 Client-Side Token Usage

File: public/break_escape/js/api-client.js

headers: {
  'Content-Type': 'application/json',
  'X-CSRF-Token': CSRF_TOKEN  // From config.js
}

9.3.3 Error Handling

File: public/break_escape/js/config.js

export const CSRF_TOKEN = window.breakEscapeConfig?.csrfToken;

if (!CSRF_TOKEN) {
  console.error('❌ CSRF token not configured!');
  console.error('All POST/PUT requests will fail');
}

// Fallback to meta tag
export const CSRF_TOKEN = window.breakEscapeConfig?.csrfToken
  || document.querySelector('meta[name="csrf-token"]')?.content;

9.3.4 Testing Procedures

Complete browser console tests provided:

• ✅ Verify token loaded
• ✅ Test GET (no CSRF needed)
• ❌ Test POST without CSRF (should fail 422)
• ✅ Test POST with CSRF (should work)

9.3.5 Common Issues & Solutions

5 common CSRF problems documented with solutions:

1. "Can't verify CSRF token authenticity"
2. Token is null/undefined
3. Token changes between requests
4. Development vs production config
5. Missing meta tags

Risk Mitigation

Before: 🔴 Critical risk - CSRF not documented After: 🟢 Low risk - Complete implementation with error handling

---

3. Async Unlock Validation with Loading UI (Phase 9.5)

What Was Added

Location: 03_IMPLEMENTATION_PLAN_PART2.md Section 9.5 (ENHANCED)

Enhancement: Complete async server validation with Phaser.js visual feedback.

Why This Is Critical

Current implementation validates unlocks client-side (insecure). New implementation:

• ✅ Validates server-side (secure)
• ✅ Shows loading feedback (~100-300ms API call)
• ✅ Handles errors gracefully
• ✅ Maintains smooth UX

Implementation Details

9.5.1 Loading UI System

NEW File: public/break_escape/js/utils/unlock-loading-ui.js

Features:

• showUnlockLoading(sprite) - Blue pulsing tint effect
• clearUnlockLoading(sprite, success) - Green (success) or red (failure) flash
• showLoadingSpinner(sprite) - Alternative rotating spinner
• Phaser.js tweens for smooth animations

Visual Feedback:

User tries unlock
  ↓
Throbbing blue tint starts (pulsing 0.7 ↔ 1.0 alpha)
  ↓
Server validates (~100-300ms)
  ↓
Success: Quick green flash → clear tint
Failure: Quick red flash → clear tint

9.5.2 Server Validation Integration

Modified: public/break_escape/js/systems/unlock-system.js

Key Changes:

// Before: Client-side validation
export function unlockTarget(lockable, type, layer) {
    // Directly unlock without server check
    unlockDoor(lockable);
}

// After: Server validation with loading UI
export async function unlockTarget(lockable, type, layer, attempt, method) {
    // Show loading
    showUnlockLoading(lockable);

    try {
        // Validate with server
        const result = await ApiClient.unlock(type, targetId, attempt, method);

        // Clear loading (success)
        clearUnlockLoading(lockable, true);

        if (result.success) {
            // Perform client-side unlock
            unlockDoor(lockable);
        }
    } catch (error) {
        // Clear loading (failure)
        clearUnlockLoading(lockable, false);

        // Show error
        window.gameAlert('Failed to validate unlock', 'error');
    }
}

9.5.3 Minigame Callback Updates

All lock types updated to pass attempt and method:

1. PIN: (success, enteredPin) => unlockTarget(..., enteredPin, 'pin')
2. Password: (success, enteredPassword) => unlockTarget(..., enteredPassword, 'password')
3. Key: (lockable, type, layer, keyId) => unlockTarget(..., keyId, 'key')
4. Lockpick: unlockTarget(..., 'lockpick', 'lockpick')
5. Biometric: unlockTarget(..., requiredFingerprint, 'biometric')
6. Bluetooth: unlockTarget(..., requiredDevice, 'bluetooth')
7. RFID: (success, cardId) => unlockTarget(..., cardId, 'rfid')

9.5.4 Testing Fallback

Development mode bypass:

// Disable server validation for testing
window.DISABLE_SERVER_VALIDATION = true;

// System falls back to client-side unlock

User Experience Flow

Before (Client-Side):

User enters password → Instant unlock (no security)

After (Server-Side with Loading UI):

User enters password
  ↓
Door starts pulsing blue (visual feedback)
  ↓
Server validates (~200ms)
  ↓
Door flashes green → Unlocks smoothly

On Failure:

User enters wrong password
  ↓
Door starts pulsing blue
  ↓
Server rejects (~200ms)
  ↓
Door flashes red → Shows error message

Risk Mitigation

Before: 🔴 Critical risk - Async validation not implemented After: 🟢 Low risk - Complete implementation with graceful UX
