docs: Clarify CSRF token handling for Hacktivity integration

User correctly noted that Hacktivity's application layout already includes csrf_meta_tags, so we don't need to add them again. ## Changes: ### Section 9.3.1: Layout Strategy - Split into Option A (Hacktivity layout - recommended) and Option B (standalone) - **Option A (Recommended):** Read from existing meta tag - Uses Hacktivity's csrf_meta_tags (already present in layout) - No duplicate meta tags needed - Reads via: document.querySelector('meta[name="csrf-token"]')?.content - **Option B:** Standalone layout - For when engine needs separate layout - Must add <%= csrf_meta_tags %> to engine layout - Can use <%= form_authenticity_token %> directly ### Section 9.3.3: Token Reading Logic - Updated config.js to try multiple sources: 1. window.breakEscapeConfig.csrfToken (if explicitly set) 2. meta[name="csrf-token"] tag (from Hacktivity layout) - Better error messages showing all sources checked - Logs which source provided the token ### Section 9.3.5: Issue #2 Solution - Updated to reference the fallback logic in 9.3.3 - Added debugging console commands - Shows how to check all meta tags ## Key Points: - ✅ Hacktivity layout csrf_meta_tags are reused (don't duplicate) - ✅ Fallback chain ensures token found from either source - ✅ Clear guidance for both integration scenarios - ✅ Better debugging when token is missing This aligns with Rails best practices and Hacktivity's existing setup.

 ### 9.3 Setup CSRF Token Injection (Critical for Security)

-**CRITICAL:** Rails requires CSRF tokens for all POST/PUT/DELETE requests. The token must be injected from the server-rendered view into JavaScript.
+**CRITICAL:** Rails requires CSRF tokens for all POST/PUT/DELETE requests. The token must be accessible to JavaScript for API calls.

-#### 9.3.1 Update Game Show View
+**IMPORTANT:** If using Hacktivity's application layout, `<%= csrf_meta_tags %>` is already present! You only need to read the existing token.

-**Edit the view that renders the game:**
+#### 9.3.1 Determine Your Layout Strategy

-```bash
-vim app/views/break_escape/games/show.html.erb
-```
+**Option A: Using Hacktivity's Application Layout (Recommended)**

-**Add JavaScript configuration block with CSRF token:**
+If your view uses Hacktivity's layout:

 ```erb
+<!-- app/views/break_escape/games/show.html.erb -->
+<!-- Hacktivity's layout already includes <%= csrf_meta_tags %> -->
+
+<div id="game-container"></div>
+
+<!-- CRITICAL: Inject configuration before loading game -->
+<%= javascript_tag nonce: true do %>
+  // BreakEscape Configuration
+  window.breakEscapeConfig = {
+    gameId: <%= @game.id %>,
+    apiBasePath: '<%= break_escape_path %>/games/<%= @game.id %>',
+    assetsPath: '/break_escape/assets',
+    // Read CSRF token from meta tag (already in layout)
+    csrfToken: document.querySelector('meta[name="csrf-token"]')?.content,
+    missionName: '<%= j @game.mission.display_name %>',
+    startRoom: '<%= j @game.scenario_data["startRoom"] %>',
+    debug: <%= Rails.env.development? %>
+  };
+
+  console.log('✓ BreakEscape config loaded:', window.breakEscapeConfig);
+<% end %>
+
+<!-- Load Phaser -->
+<script src="/break_escape/js/phaser.min.js"></script>
+
+<!-- Load game (as ES6 module) -->
+<script type="module" src="/break_escape/js/main.js"></script>
+```
+
+**Advantages:**
+- ✅ Uses Hacktivity's existing CSRF setup
+- ✅ Consistent with other Hacktivity pages
+- ✅ Automatic CSRF token rotation handled by Hacktivity
+- ✅ No duplicate meta tags
+
+**Option B: Standalone Layout for Engine**
+
+If you create a standalone layout for the engine:
+
+```erb
+<!-- app/views/layouts/break_escape/application.html.erb -->
 <!DOCTYPE html>
 <html>
 <head>
-  <title>Break Escape - <%= @game.mission.display_name %></title>
-  <%= csrf_meta_tags %>
+  <title>Break Escape - <%= yield :title %></title>
+  <%= csrf_meta_tags %>  <!-- REQUIRED: Add this -->
  <%= csp_meta_tag %>

  <!-- Game CSS -->
  <%= stylesheet_link_tag '/break_escape/css/game.css' %>
-
-  <!-- CRITICAL: Inject configuration before loading game -->
-  <%= javascript_tag nonce: true do %>
-    // BreakEscape Configuration
-    window.breakEscapeConfig = {
-      gameId: <%= @game.id %>,
-      apiBasePath: '<%= break_escape_path %>/games/<%= @game.id %>',
-      assetsPath: '/break_escape/assets',
-      csrfToken: '<%= form_authenticity_token %>',
-      missionName: '<%= j @game.mission.display_name %>',
-      startRoom: '<%= j @game.scenario_data["startRoom"] %>',
-      debug: <%= Rails.env.development? %>
-    };
-
-    console.log('✓ BreakEscape config loaded:', window.breakEscapeConfig);
-  <% end %>
 </head>
 <body>
-  <div id="game-container"></div>
-
-  <!-- Load Phaser -->
-  <script src="/break_escape/js/phaser.min.js"></script>
-
-  <!-- Load game (as ES6 module) -->
-  <script type="module" src="/break_escape/js/main.js"></script>
+  <%= yield %>
 </body>
 </html>
 ```

-**Key points:**
- `<%= csrf_meta_tags %>` - Required by Rails, adds meta tags
- `<%= form_authenticity_token %>` - Generates CSRF token for this session
- `nonce: true` - Required if using Content Security Policy
- Configuration loaded BEFORE game scripts
- Token stored in `window.breakEscapeConfig.csrfToken`
+```erb
+<!-- app/views/break_escape/games/show.html.erb -->
+<% content_for :title, @game.mission.display_name %>
+
+<div id="game-container"></div>
+
+<%= 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 %>',  // Generate fresh token
+    missionName: '<%= j @game.mission.display_name %>',
+    startRoom: '<%= j @game.scenario_data["startRoom"] %>',
+    debug: <%= Rails.env.development? %>
+  };
+<% end %>
+
+<script src="/break_escape/js/phaser.min.js"></script>
+<script type="module" src="/break_escape/js/main.js"></script>
+```
+
+**When to use:**
+- ✅ Engine needs different layout than Hacktivity
+- ✅ Full-screen game experience
+- ✅ Standalone mode (engine runs independently)
+
+#### 9.3.1a Verify CSRF Meta Tag Exists
+
+**Check that the meta tag is in the rendered HTML:**
+
+```bash
+# Start Rails server
+rails server
+
+# Visit game page
+# View page source (Ctrl+U or Cmd+Option+U)
+```
+
+**Look for this in <head>:**
+```html
+<meta name="csrf-token" content="AaBbCc123...long base64 string..." />
+```
+
+**If missing:**
+- Check if using Hacktivity's layout
+- If standalone layout, add `<%= csrf_meta_tags %>`
+- Check `config/application.rb` - forgery protection should be enabled

+# 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
+
+```bash
+# 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`
+
+```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`
+
+```javascript
+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`
+
+```javascript
+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:**
+
+```javascript
+// 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:**
+
+```javascript
+// 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
+
