# Rails Engine Migration Plan - Review 1
## Executive Summary
**Date:** November 20, 2025
**Reviewer:** Claude (Automated Code Review)
**Documents Reviewed:** All files in `planning_notes/rails-engine-migration-json/`
**Codebase State:** Current BreakEscape repository as of commit `e9c73aa`
---
## Overall Assessment
**Status: MOSTLY SOLID - REQUIRES CRITICAL CORRECTIONS BEFORE IMPLEMENTATION**
The Rails Engine migration plan is **well-structured** and follows sound architectural principles. The JSON-centric approach is appropriate and will significantly simplify the migration compared to the original complex relational database approach.
However, **critical discrepancies** have been identified between the plan's assumptions and the actual codebase structure that **MUST** be addressed before beginning implementation.
---
## Key Findings Summary
### ✅ Strengths
1. **Simplified Architecture**: JSON-centric JSONB approach is excellent for this use case
2. **Clear Documentation**: 8 comprehensive documents with step-by-step instructions
3. **Hacktivity Compatibility**: Thoroughly validated against actual Hacktivity codebase
4. **Phased Approach**: 12 phases with clear milestones and testing points
5. **Minimal Client Changes**: Plan correctly minimizes client-side rewrites
### ⚠️ Critical Issues Requiring Immediate Attention
1. **NPC Ink File Structure Mismatch** (CRITICAL)
- Plan assumes: `.ink` and `.ink.json` files for all NPCs
- Reality: 30 `.ink` files, only 3 `.ink.json` files
- Scenarios reference `.json` files (not `.ink.json`)
- **Impact**: Phase 3 file reorganization will fail
2. **Scenario-NPC Relationship** (HIGH)
- Plan assumes: Each scenario has dedicated NPC scripts
- Reality: Many NPCs are shared across scenarios (test-npc.json used 10+ times)
- **Impact**: Database schema needs adjustment, seed script will fail
3. **Missing Compilation Step** (CRITICAL)
- Plan doesn't account for compiling `.ink``.json`
- No tooling documented for Ink compilation in Rails context
- **Impact**: NPC scripts won't work without compilation pipeline
4. **Global State Management** (MEDIUM)
- `window.gameState` has expanded beyond what's tracked in plan
- Includes: `biometricSamples`, `bluetoothDevices`, `notes`, `startTime`
- **Impact**: Incomplete state persistence, potential data loss
5. **Room Loading Architecture** (MEDIUM)
- Plan assumes Tiled JSON maps loaded via API
- Current codebase: Tiled maps loaded statically from `assets/rooms/`
- **Impact**: API endpoint design incomplete
### 📊 Risk Level: MEDIUM-HIGH
Without addressing critical issues, implementation will encounter:
- **Build failures** in Phase 3 (file reorganization)
- **Seed failures** in Phase 5 (scenario import)
- **Runtime errors** when NPCs are encountered
- **Incomplete game state** persistence
---
## Recommendation
**DO NOT BEGIN IMPLEMENTATION** until critical issues are resolved.
**Recommended Actions:**
1. Update Phase 3 to handle `.ink``.json` compilation
2. Add shared NPC script support to database schema
3. Document Ink compilation toolchain
4. Extend `player_state` JSONB schema to include missing gameState fields
5. Clarify room asset loading strategy
**Estimated Delay:** 1-2 days to update plans, no impact to overall timeline if done first.

# Critical Issues - Detailed Analysis
This document provides in-depth analysis of critical issues that **MUST** be resolved before implementation.
---
## Issue #1: NPC Ink File Structure Mismatch
**Severity:** 🔴 CRITICAL - Will cause build failures
**Phase Impact:** Phase 3, Phase 5
**Effort to Fix:** 2-4 hours
### Problem Description
The migration plan makes incorrect assumptions about Ink file organization:
**Plan Assumes:**
```
app/assets/scenarios/ceo_exfil/ink/
├── security_guard.ink ✓ EXISTS
├── security_guard.ink.json ✗ DOES NOT EXIST
├── neye_eve.ink ✗ DOES NOT EXIST
├── neye_eve.ink.json ✗ DOES NOT EXIST
```
**Actual Codebase:**
```
scenarios/ink/
├── security-guard.ink ✓ EXISTS (hyphenated)
├── neye-eve.json ✓ EXISTS (compiled, not .ink.json)
├── gossip-girl.json ✓ EXISTS
├── helper-npc.json ✓ EXISTS
├── alice-chat.ink ✓ EXISTS
├── alice-chat.ink.json ✓ EXISTS (only 3 files have .ink.json)
└── ... 30 total .ink files
```
**Scenarios Reference:**
```json
{
"storyPath": "scenarios/ink/neye-eve.json" // Not .ink.json!
}
```
### Evidence
From codebase analysis:
```bash
# Ink source files
$ find scenarios/ink -name "*.ink" | wc -l
30
# Compiled ink files (.ink.json format)
$ ls scenarios/ink/*.ink.json
alice-chat.ink.json
mixed-message-example.ink.json
voice-message-example.ink.json
# Regular JSON files (compiled ink without .ink extension)
$ ls scenarios/ink/*.json | wc -l
26
```
From scenario files:
```json
// scenarios/ceo_exfil.json
{
"npcs": [
{
"id": "neye_eve",
"storyPath": "scenarios/ink/neye-eve.json" // ← .json, not .ink.json
}
]
}
```
### Root Cause
The codebase uses **inconsistent naming conventions**:
- Some files: `name.ink.json` (Ink's default output)
- Most files: `name.json` (manually renamed for cleaner paths)
- Scenarios expect: `.json` extension
Additionally, **not all .ink files have been compiled**:
- 30 source `.ink` files exist
- Only 3-5 compiled files exist
- Missing compilation step in workflow
### Impact on Migration Plan
**Phase 3: Reorganize Scenarios (Week 1-2)**
```bash
# This command will FAIL:
mv "scenarios/ink/security_guard.ink.json" "app/assets/scenarios/${SCENARIO}/ink/"
# Error: No such file or directory
```
**Phase 5: Scenario Import (Week 2)**
```ruby
# This code will FAIL:
ink_json_path = Rails.root.join('app/assets/scenarios', scenario_name, 'ink', "#{npc_id}.ink.json")
# Error: File not found (looking for .ink.json, but files are .json)
```
### Required Fixes
#### Fix 1: Update File Movement Commands (Phase 3)
**Before:**
```bash
mv "scenarios/ink/security_guard.ink" "app/assets/scenarios/${SCENARIO}/ink/"
mv "scenarios/ink/security_guard.ink.json" "app/assets/scenarios/${SCENARIO}/ink/"
```
**After:**
```bash
# Move .ink source
mv "scenarios/ink/security-guard.ink" "app/assets/scenarios/${SCENARIO}/ink/"
# Move compiled .json (check both patterns)
if [ -f "scenarios/ink/security-guard.ink.json" ]; then
mv "scenarios/ink/security-guard.ink.json" "app/assets/scenarios/${SCENARIO}/ink/"
elif [ -f "scenarios/ink/security-guard.json" ]; then
mv "scenarios/ink/security-guard.json" "app/assets/scenarios/${SCENARIO}/ink/"
fi
```
#### Fix 2: Add Ink Compilation Step
**New Phase 2.5: Compile Ink Scripts**
```bash
# Install Inklecate (Ink compiler)
npm install -g inkjs
# Compile all .ink files to .json
for ink_file in scenarios/ink/*.ink; do
base_name=$(basename "$ink_file" .ink)
# Skip if already compiled as .json
if [ ! -f "scenarios/ink/${base_name}.json" ] && [ ! -f "scenarios/ink/${base_name}.ink.json" ]; then
echo "Compiling $ink_file..."
inklecate -o "scenarios/ink/${base_name}.json" "$ink_file"
fi
done
```
#### Fix 3: Update ScenarioLoader (Phase 5)
**Before:**
```ruby
ink_json_path = Rails.root.join('app/assets/scenarios', scenario_name, 'ink', "#{npc_id}.ink.json")
```
**After:**
```ruby
# Check both .json and .ink.json patterns
json_path = Rails.root.join('app/assets/scenarios', scenario_name, 'ink', "#{npc_id}.json")
ink_json_path = Rails.root.join('app/assets/scenarios', scenario_name, 'ink', "#{npc_id}.ink.json")
compiled_path = File.exist?(ink_json_path) ? ink_json_path : json_path
next unless File.exist?(compiled_path)
npc_script.ink_compiled = File.read(compiled_path)
```
---
## Issue #2: Scenario-NPC Relationship (Shared NPCs)
**Severity:** 🟠 HIGH - Will cause seed failures and data duplication
**Phase Impact:** Phase 4 (Database), Phase 5 (Seeds)
**Effort to Fix:** 3-5 hours
### Problem Description
The database schema assumes **1:1 relationship** between scenarios and NPCs:
**Current Schema:**
```ruby
create_table :break_escape_npc_scripts do |t|
t.references :scenario, null: false
t.string :npc_id, null: false
t.index [:scenario_id, :npc_id], unique: true # ← Assumes unique per scenario
end
```
**Actual Codebase:**
Many NPCs are **shared across scenarios**:
```
scenarios/ink/test-npc.json → Used in 10+ test scenarios
scenarios/ink/generic-npc.json → Reusable helper NPC
scenarios/ink/haxolottle_hub.json → Shared across hub scenarios
```
From grep analysis:
```
scenarios/test-npc-face-player.json: Uses test-npc.json (10 times)
scenarios/npc-hub-demo-ghost-protocol.json: Uses netherton_hub.json, chen_hub.json, haxolottle_hub.json
```
### Impact
**Database Constraint Violation:**
- Seed script will try to create same NPC for multiple scenarios
- Unique index will fail on second scenario
- OR: Wasteful duplication (same script stored 10+ times)
**Example Failure:**
```ruby
# Scenario 1: test-npc-face-player
NpcScript.create!(scenario_id: 1, npc_id: 'test_npc', ink_compiled: '...') # ✓ Success
# Scenario 2: test-npc-pathfinding
NpcScript.create!(scenario_id: 2, npc_id: 'test_npc', ink_compiled: '...') # ✓ Success (duplicate!)
# Result: Same script stored twice, 2x database usage
```
### Required Fixes
#### Option A: Allow Shared NPCs (Recommended)
**Update Schema:**
```ruby
create_table :break_escape_npc_scripts do |t|
t.string :npc_id, null: false # Remove scenario_id FK
t.text :ink_source
t.text :ink_compiled, null: false
t.timestamps
t.index :npc_id, unique: true # Global NPC registry
end
# New join table for scenario-npc relationships
create_table :break_escape_scenario_npcs do |t|
t.references :scenario, null: false, foreign_key: { to_table: :break_escape_scenarios }
t.references :npc_script, null: false, foreign_key: { to_table: :break_escape_npc_scripts }
t.timestamps
t.index [:scenario_id, :npc_script_id], unique: true
end
```
**Pros:**
- Eliminates duplication
- Matches actual codebase usage
- Easier to update shared NPCs globally
**Cons:**
- Slightly more complex queries
- Migration plan needs updating
#### Option B: Namespace NPCs per Scenario
Keep current schema, but change seed logic:
```ruby
npc_script_id = "#{scenario_name}_#{npc_id}" # e.g., "ceo_exfil_security_guard"
```
**Pros:**
- Minimal schema changes
- Simple implementation
**Cons:**
- Duplicates shared NPCs across scenarios
- Harder to update global NPCs
- Wastes database space
### Recommendation
**Use Option A** - The join table approach is more correct and matches the actual sharing patterns in the codebase.

## Issue #3: Missing Ink Compilation Pipeline
**Severity:** 🔴 CRITICAL - NPCs won't function without compiled scripts
**Phase Impact:** Phase 2-5
**Effort to Fix:** 4-6 hours
### Problem Description
The plan doesn't document:
1. How to compile `.ink` files to `.json`
2. Where compilation happens (local dev? CI? deployment?)
3. How to handle ERB + Ink compilation together
4. Version control for compiled files
### Current State
**What exists:**
- 30 `.ink` source files
- 3-5 compiled `.json` files
- No documented compilation process
- No Rakefile tasks for compilation
**What's missing:**
- Ink compiler installation instructions
- Automated compilation workflow
- Integration with Rails asset pipeline
- CI/CD compilation step
### Impact
**Without compilation:**
```ruby
# Phase 5 seed will fail:
npc_script.ink_compiled = File.read(ink_json_path)
# Error: File not found (never compiled)
```
**Runtime impact:**
```javascript
// Client tries to load NPC script
const script = await fetch('/api/games/123/npcs/security_guard/script');
// Returns empty/null - game breaks
```
### Required Fixes
#### Fix 1: Add Compilation Documentation
**New Section in 02_IMPLEMENTATION_PLAN.md:**
```markdown
## Phase 2.5: Compile Ink Scripts (Week 1)
### Prerequisites
Install Ink compiler:
```bash
# Option A: Via npm
npm install -g inkjs
npm install -g inklecate-cli
# Option B: Download binary
wget https://github.com/inkle/ink/releases/download/v1.1.1/inklecate_linux.zip
unzip inklecate_linux.zip
chmod +x inklecate
sudo mv inklecate /usr/local/bin/
```
### Compile All Scripts
```bash
# Create compilation script
cat > scripts/compile_ink.sh << 'EOF'
#!/bin/bash
for ink_file in scenarios/ink/*.ink; do
base=$(basename "$ink_file" .ink)
json_out="scenarios/ink/${base}.json"
# Skip if up-to-date
if [ -f "$json_out" ] && [ "$json_out" -nt "$ink_file" ]; then
echo "✓ $base.json is up to date"
continue
fi
echo "Compiling $base.ink..."
inklecate -o "$json_out" "$ink_file"
if [ $? -eq 0 ]; then
echo " ✓ Compiled to $base.json"
else
echo " ✗ Compilation failed"
exit 1
fi
done
EOF
chmod +x scripts/compile_ink.sh
./scripts/compile_ink.sh
```
**Commit:**
```bash
git add scenarios/ink/*.json scripts/compile_ink.sh
git commit -m "feat: Add Ink compilation script and compile all NPCs"
```
```
#### Fix 2: Add Rake Task
```ruby
# lib/tasks/ink.rake
namespace :break_escape do
namespace :ink do
desc "Compile all .ink files to .json"
task :compile do
require 'open3'
ink_dir = Rails.root.join('app/assets/scenarios')
compiled = 0
failed = 0
Dir.glob(ink_dir.join('**/*.ink')).each do |ink_file|
json_file = ink_file.gsub(/\.ink$/, '.json')
# Skip if up-to-date
next if File.exist?(json_file) && File.mtime(json_file) > File.mtime(ink_file)
puts "Compiling #{File.basename(ink_file)}..."
stdout, stderr, status = Open3.capture3("inklecate", "-o", json_file, ink_file)
if status.success?
compiled += 1
puts " ✓ Compiled"
else
failed += 1
puts " ✗ Failed: #{stderr}"
end
end
puts "\n✓ Compiled #{compiled} files"
puts "✗ Failed #{failed} files" if failed > 0
end
desc "Watch .ink files and auto-compile on changes"
task :watch do
require 'listen'
puts "👀 Watching for .ink file changes..."
listener = Listen.to(Rails.root.join('app/assets/scenarios'), only: /\.ink$/) do |modified, added, removed|
(modified + added).each do |file|
Rake::Task['break_escape:ink:compile'].execute
end
end
listener.start
sleep
end
end
end
```
#### Fix 3: Add to Deployment Pipeline
**Heroku/Production:**
```ruby
# config/initializers/break_escape.rb (after engine initialization)
if Rails.env.production? && !ENV['SKIP_INK_COMPILE']
Rails.logger.info "Compiling Ink scripts for production..."
Rake::Task['break_escape:ink:compile'].invoke
end
```
**CI/CD (.github/workflows/test.yml):**
```yaml
- name: Compile Ink scripts
run: |
npm install -g inklecate-cli
bundle exec rake break_escape:ink:compile
```
---
## Issue #4: Incomplete Global State Tracking
**Severity:** 🟡 MEDIUM - State loss, potential bugs
**Phase Impact:** Phase 4 (Schema), Phase 9 (Client)
**Effort to Fix:** 1-2 hours
### Problem Description
The `player_state` JSONB schema doesn't include all fields from `window.gameState`:
**Plan Schema:**
```json
{
"currentRoom": "...",
"position": {"x": 0, "y": 0},
"unlockedRooms": [],
"unlockedObjects": [],
"inventory": [],
"encounteredNPCs": [],
"globalVariables": {}
}
```
**Actual window.gameState (js/main.js:46):**
```javascript
window.gameState = {
biometricSamples: [], // ← MISSING
biometricUnlocks: [], // ← MISSING
bluetoothDevices: [], // ← MISSING
notes: [], // ← MISSING
startTime: null // ← MISSING
};
```
### Impact
**Data Loss:**
- Player collects biometric samples → Lost on page reload
- Player scans Bluetooth devices → Lost on page reload
- Player reads notes → Lost on page reload
**Broken Minigames:**
- Biometrics minigame relies on `biometricSamples` array
- Bluetooth scanner relies on `bluetoothDevices` array
- Notes system relies on `notes` array
### Required Fix
**Update Migration (Phase 4):**
```ruby
t.jsonb :player_state, null: false, default: {
currentRoom: nil,
position: { x: 0, y: 0 },
unlockedRooms: [],
unlockedObjects: [],
inventory: [],
encounteredNPCs: [],
globalVariables: {},
# Add missing fields
biometricSamples: [], # { type: 'fingerprint', data: '...', source: '...' }
biometricUnlocks: [], # ['door_ceo', 'safe_123']
bluetoothDevices: [], # { name: '...', mac: '...', distance: ... }
notes: [], # { id: '...', title: '...', content: '...' }
startTime: nil # ISO8601 timestamp
}
```
**Update GameInstance Model:**
```ruby
def sync_minigame_state!(minigame_data)
player_state['biometricSamples'] = minigame_data['biometricSamples'] if minigame_data['biometricSamples']
player_state['bluetoothDevices'] = minigame_data['bluetoothDevices'] if minigame_data['bluetoothDevices']
player_state['notes'] = minigame_data['notes'] if minigame_data['notes']
save!
end
```
---
## Issue #5: Room Asset Loading Strategy Unclear
**Severity:** 🟡 MEDIUM - API design incomplete
**Phase Impact:** Phase 6 (API), Phase 9 (Client)
**Effort to Fix:** 2-3 hours
### Problem Description
The plan's API design doesn't clarify how Tiled map JSON files are served.
**Current Codebase (js/core/game.js:32):**
```javascript
// Phaser loads Tiled maps directly
this.load.tilemapTiledJSON('room_reception', 'assets/rooms/room_reception2.json');
this.load.tilemapTiledJSON('room_office', 'assets/rooms/room_office2.json');
```
**Plan's API (01_ARCHITECTURE.md:494):**
```
GET /api/games/:game_id/rooms/:room_id
Response:
{
"roomId": "room_office",
"type": "office",
"connections": {...},
"objects": [...]
}
```
**Confusion:**
- Does API return Tiled map JSON or filtered game data?
- Where do Tiled `.json` files live after migration?
- How does Phaser load Tiled maps (static assets vs API)?
### Current Structure
```
assets/rooms/
├── room_reception2.json (Tiled map)
├── room_office2.json (Tiled map)
├── room_ceo2.json (Tiled map)
...
scenarios/ceo_exfil.json (Game logic: objects, NPCs, locks)
```
**Two different data structures:**
1. **Tiled maps** (.json) - Visual layout, tiles, collision layers
2. **Scenario data** (.json) - Game objects, locks, NPCs, connections
### Required Clarification
**Recommended Approach:**
1. **Keep Tiled maps as static assets:**
```bash
# Move to public/break_escape/
mv assets/rooms public/break_escape/assets/
```
2. **API returns game logic only:**
```ruby
def show
room_data = @game_instance.scenario.filtered_room_data(params[:room_id])
render json: {
roomId: params[:room_id],
# Game logic (from scenario)
connections: room_data['connections'],
objects: room_data['objects'],
npcs: room_data['npcs'],
locked: room_data['locked'],
# Tiled map reference (loaded separately by Phaser)
tiledMap: room_data['type'] # e.g., 'room_reception'
}
end
```
3. **Client loads both:**
```javascript
// 1. Load Tiled map (static asset)
this.load.tilemapTiledJSON(roomData.tiledMap, `/break_escape/assets/rooms/${roomData.tiledMap}.json`);
// 2. Load game logic (API)
const gameData = await apiGet(`/rooms/${roomId}`);
```

# Architecture Review
This document validates the technical design decisions in the migration plan.
---
## Database Design
### ✅ JSON-Centric Approach - EXCELLENT
**Decision:** Use JSONB columns for flexible state storage instead of normalized relational tables.
**Validation:****CORRECT CHOICE**
**Reasoning:**
1. **Game state is hierarchical** - Perfect fit for JSON structure
2. **Rapid iteration** - Can add new state fields without migrations
3. **PostgreSQL JSONB performance** - GIN indexes provide fast queries
4. **Scenario data varies** - Each scenario has different objects/rooms
5. **Reduces complexity** - 3 tables vs 10+ with proper indexes
**Evidence from similar systems:**
- Many game backends use document stores (MongoDB, Firestore)
- Rails + JSONB provides best of both worlds
- Hacktivity already uses PostgreSQL (validated in 05_HACKTIVITY_INTEGRATION.md)
**Recommendation:** ✅ Keep this approach
---
## Polymorphic Player Association
### ✅ Polymorphic Design - CORRECT
**Decision:** Use polymorphic `belongs_to :player` for User or DemoUser.
```ruby
belongs_to :player, polymorphic: true
```
**Validation:****CORRECT FOR REQUIREMENTS**
**Reasoning:**
1. **Supports standalone mode** - DemoUser for development
2. **Integrates with Hacktivity** - Uses existing User model
3. **Rails standard pattern** - Well-documented and tested
4. **Authorization compatible** - Pundit handles polymorphic associations
**Hacktivity Compatibility:**
```ruby
# Hacktivity User model has methods needed:
user.admin? # ✓ Exists
user.account_manager? # ✓ Exists
user.handle # ✓ Exists
```
**Recommendation:** ✅ Keep this approach
---
## API Design
### ✅ Session-Based Authentication - APPROPRIATE
**Decision:** Use Rails session-based auth (not JWT).
**Validation:****MATCHES HACKTIVITY ARCHITECTURE**
**Reasoning:**
1. **Hacktivity uses Devise** - Session-based by default
2. **Simplifies integration** - No token management needed
3. **CSRF protection** - Built-in with Rails
4. **Secure cookies** - HTTPOnly, Secure flags
5. **No mobile app requirement** - Web-only use case
**Alternative Considered:** JWT tokens
**Why Rejected:** Adds complexity without benefit for web-only game
**Recommendation:** ✅ Keep session-based auth
---
### ✅ 6 API Endpoints - MINIMAL AND SUFFICIENT
**Decision:** Limit API surface to 6 essential endpoints.
**Validation:****CORRECT SCOPE**
**Endpoints:**
1. `GET /bootstrap` - Initial game data
2. `PUT /sync_state` - Periodic state sync
3. `POST /unlock` - Server-side validation
4. `POST /inventory` - Inventory updates
5. `GET /rooms/:id` - Load room data
6. `GET /npcs/:id/script` - Lazy-load NPC scripts
**Coverage Analysis:**
- ✅ Unlocking (critical validation)
- ✅ Inventory management
- ✅ NPC interactions
- ✅ Room discovery
- ✅ State persistence
- ⚠️ Missing: Minigame results, combat events (see recommendations)
**Recommendation:** ✅ Keep core 6, consider 2 additions (see 05_RECOMMENDATIONS.md)
---
## Database Schema
### ⚠️ NPC Scripts Table - NEEDS ADJUSTMENT
**Current Design:**
```ruby
create_table :break_escape_npc_scripts do |t|
t.references :scenario, null: false
t.string :npc_id, null: false
t.index [:scenario_id, :npc_id], unique: true
end
```
**Issue:** Doesn't support shared NPCs across scenarios.
**Validation:****INCORRECT FOR CODEBASE**
**Evidence:**
- `test-npc.json` used in 10+ scenarios
- `generic-npc.json` designed for reuse
- Hub NPCs (`haxolottle_hub.json`) shared across scenarios
**Recommendation:** ⚠️ See recommended fix in 06_UPDATED_SCHEMA.md
---
### ✅ Game Instances Table - WELL DESIGNED
**Schema:**
```ruby
create_table :break_escape_game_instances do |t|
t.references :player, polymorphic: true
t.references :scenario
t.jsonb :player_state, default: { ... }
t.string :status
t.datetime :started_at, :completed_at
t.integer :score, :health
end
```
**Validation:****SOLID DESIGN** (with minor additions)
**Strengths:**
1. Polymorphic player ✅
2. JSONB for flexible state ✅
3. Status tracking ✅
4. Timestamps for analytics ✅
5. GIN index on player_state ✅
**Missing Fields (non-critical):**
- `attempts` counter - How many times player retried
- `hints_used` - Track hint system usage
- `time_elapsed` - For leaderboards
**Recommendation:** ✅ Core design is good, minor additions recommended
---
## Routes Design
### ✅ Engine Mounting - CORRECT PATTERN
**Decision:** Mount engine at `/break_escape` in Hacktivity.
```ruby
# Hacktivity config/routes.rb
mount BreakEscape::Engine => "/break_escape"
```
**Validation:****MATCHES HACKTIVITY PATTERNS**
**Evidence:**
```ruby
# From Hacktivity routes.rb (provided by user):
mount Resque::Server.new, at: "/resque"
# Same pattern ✓
```
**Path Structure:**
```

https://hacktivity.com/break_escape/api/games/123/bootstrap
```
**Recommendation:** ✅ Keep this approach
---
## File Organization
### ✅ Static Assets in public/ - CORRECT
**Decision:** Move game files to `public/break_escape/`
**Validation:****CORRECT FOR RAILS ENGINES**
**Structure:**
```
public/break_escape/
├── js/ (ES6 modules, unchanged)
├── css/ (stylesheets)
└── assets/ (images, sounds, Tiled maps)
```
**Reasoning:**
1. **Engine isolation** - Assets namespaced under /break_escape/
2. **No asset pipeline** - Simpler deployment
3. **Direct serving** - Nginx/Apache can serve static files
4. **Phaser compatibility** - Expects direct asset URLs
**Alternative Considered:** Rails asset pipeline
**Why Rejected:**
- Adds build complexity
- Phaser needs direct file paths
- No benefit for this use case
**Recommendation:** ✅ Keep static assets in public/
---
### ⚠️ Scenarios in app/assets/ - QUESTIONABLE
**Decision:** Store scenarios in `app/assets/scenarios/` with ERB templates.
**Validation:** ⚠️ **UNCONVENTIONAL BUT ACCEPTABLE**
**Reasoning:**
- `app/assets/` typically for CSS/JS/images
- ERB processing needed for randomization
- Not served directly to client (processed server-side)
**Alternative:** `lib/break_escape/scenarios/`
**Why Not Chosen:** Not clear from plan
**Concerns:**
1. Asset pipeline might try to process these files
2. Needs explicit exclusion from sprockets
3. Unconventional location
**Mitigation:**
```ruby
# config/initializers/assets.rb
Rails.application.config.assets.exclude_paths << Rails.root.join("app/assets/scenarios")
```
**Recommendation:** ⚠️ Consider moving to `lib/` or document exclusion
---
## Client Integration Strategy
### ✅ Minimal Changes - EXCELLENT
**Decision:** Minimize client-side code rewrites.
**Validation:****CORRECT ENGINEERING PRACTICE**
**Changes Required:**
1. **New files** (2):
- `config.js` - API configuration
- `api-client.js` - Fetch wrapper
2. **Modified files** (~5):
- Update scenario loading
- Update unlock validation
- Update NPC script loading
- Update inventory sync
- Update state persistence
**What's NOT changed:**
- ✅ Game logic (player.js, rooms.js)
- ✅ Phaser scenes (game.js)
- ✅ Minigames (all minigame files)
- ✅ NPC systems (npc-manager.js, etc.)
- ✅ UI components (ui/, systems/)
**Percentage of Code Changed:** <5% of client codebase
**Recommendation:** ✅ Excellent approach - minimizes risk
---
## ERB Template Usage
### ✅ ERB for Randomization - CLEVER SOLUTION
**Decision:** Use ERB templates for scenario randomization.
**Example:**
```erb
{
"locked": true,
"lockType": "password",
"requires": "<%= random_password %>"
}
```
**Validation:****CREATIVE AND APPROPRIATE**
**Strengths:**
1. **Simple randomization** - No complex logic needed
2. **Rails native** - No new dependencies
3. **Cacheable** - Generate once per game instance
4. **Secure** - Passwords server-side only
**Concerns:**
1. **JSON syntax errors** - ERB could break JSON
2. **No syntax checking** - Until runtime
3. **Debugging harder** - Template vs output
**Mitigation:**
```ruby
# Add JSON validation after ERB processing
def load
template_path = Rails.root.join('app/assets/scenarios', scenario_name, 'scenario.json.erb')
erb = ERB.new(File.read(template_path))
output = erb.result(binding_context.get_binding)
# Validate JSON syntax
JSON.parse(output)
rescue JSON::ParserError => e
raise "Scenario #{scenario_name} has invalid JSON after ERB processing: #{e.message}"
end
```
**Recommendation:** ✅ Keep ERB approach, add validation
---
## Testing Strategy
### ✅ Minitest with Fixtures - MATCHES HACKTIVITY
**Decision:** Use Minitest (not RSpec) with fixture-based testing.
**Validation:****CORRECT FOR COMPATIBILITY**
**Evidence from Hacktivity:**
```ruby
# test/models/user_test.rb
class UserTest < ActiveSupport::TestCase
should have_many(:events).through(:results)
should validate_presence_of(:handle)
end
```
**Plan Matches:**
```ruby
# test/models/break_escape/game_instance_test.rb
class GameInstanceTest < ActiveSupport::TestCase
test "should unlock room" do
game = game_instances(:active_game)
game.unlock_room!('room_office')
assert game.room_unlocked?('room_office')
end
end
```
**Recommendation:** ✅ Keep Minitest approach
---
## Pundit Authorization
### ✅ Pundit Policies - APPROPRIATE
**Decision:** Use Pundit for authorization (not CanCanCan).
**Validation:****CLEAN AND TESTABLE**
**Policy Example:**
```ruby
class GameInstancePolicy < ApplicationPolicy
def show?
record.player == user || user&.admin?
end
end
```
**Strengths:**
1. **Explicit policies** - Easy to understand
2. **Testable** - Unit test each policy
3. **Flexible** - Supports polymorphic associations
4. **Standard** - Well-documented gem
**Hacktivity Compatibility:**
- User model has `admin?` method ✅
- User model has `account_manager?` method ✅
- Can extend for custom roles ✅
**Recommendation:** ✅ Keep Pundit
---
## Content Security Policy
### ✅ CSP with Nonces - SECURE
**Decision:** Use CSP nonces for inline scripts.
**Validation:****MATCHES HACKTIVITY SECURITY**
**Evidence from Hacktivity:**
```erb
<%= javascript_include_tag 'application', nonce: content_security_policy_nonce %>
```
**Plan Implementation:**
```erb
<script nonce="<%= content_security_policy_nonce %>">
window.breakEscapeConfig = { ... };
</script>
```
**Security Benefits:**
1. **Prevents XSS** - Blocks unauthorized inline scripts
2. **Nonce-based** - Better than unsafe-inline
3. **Rails built-in** - No custom implementation
**Recommendation:** ✅ Keep CSP approach
---
## Summary: Architecture Score Card
| Component | Rating | Notes |
|-----------|--------|-------|
| Database (JSONB) | ✅ Excellent | Perfect for game state |
| Polymorphic Player | ✅ Correct | Supports both modes |
| API Design | ✅ Good | 6 endpoints sufficient |
| NPC Schema | ⚠️ Needs Fix | Shared NPCs issue |
| Routes/Mounting | ✅ Correct | Matches Hacktivity |
| Static Assets | ✅ Correct | public/ is right |
| Scenario Storage | ⚠️ Questionable | Consider lib/ |
| Client Changes | ✅ Minimal | <5% code change |
| ERB Templates | ✅ Clever | Add validation |
| Testing | ✅ Correct | Matches Hacktivity |
| Authorization | ✅ Correct | Pundit is good |
| Security (CSP) | ✅ Correct | Nonces match |
**Overall Architecture Grade: A-** (Would be A+ with NPC schema fix)

# Recommendations and Improvements
This document provides prioritized recommendations for improving the migration plan.
---
## Priority 0: Must-Fix Before Implementation (Blockers)
These issues **WILL** cause implementation failures if not addressed.
### P0-1: Fix Ink File Structure (Issue #1)
**Problem:** Plan assumes .ink.json files, but codebase uses .json
**Action Required:**
1. Update Phase 3 file movement commands to handle both patterns
2. Add compilation step before file reorganization
3. Update ScenarioLoader to check both file extensions
**Files to Update:**
- `02_IMPLEMENTATION_PLAN.md` - Phase 3 commands
- `02_IMPLEMENTATION_PLAN.md` - Add Phase 2.5 for compilation
**Time:** 2 hours
**Risk if skipped:** Phase 3 will fail with "file not found" errors
---
### P0-2: Add Ink Compilation Pipeline (Issue #3)
**Problem:** No documented process for compiling .ink → .json
**Action Required:**
1. Document Inklecate installation
2. Create compilation script
3. Add Rake task for compilation
4. Add to deployment pipeline
**Files to Create:**
- `scripts/compile_ink.sh`
- `lib/tasks/ink.rake`
**Files to Update:**
- `02_IMPLEMENTATION_PLAN.md` - Add Phase 2.5
- `04_TESTING_GUIDE.md` - Add compilation to CI
**Time:** 4 hours
**Risk if skipped:** NPC scripts won't work, game will break
---
### P0-3: Fix NPC Schema for Shared Scripts (Issue #2)
**Problem:** Current schema doesn't support NPCs shared across scenarios
**Action Required:**
1. Update database migration for shared NPC support
2. Add join table for scenario-npc relationships
3. Update ScenarioLoader to handle shared NPCs
4. Update models and associations
**Files to Update:**
- `02_IMPLEMENTATION_PLAN.md` - Phase 4 migrations
- `03_DATABASE_SCHEMA.md` - Schema reference
- See detailed fix in `06_UPDATED_SCHEMA.md`
**Time:** 4 hours
**Risk if skipped:** Seed script will fail or create duplicate data
---
## Priority 1: Should-Fix Before Implementation (Quality)
These issues won't block implementation but will cause bugs or data loss.
### P1-1: Extend player_state Schema (Issue #4)
**Problem:** Missing fields for minigame state
**Action Required:**
Add to player_state JSONB:
```ruby
biometricSamples: [],
biometricUnlocks: [],
bluetoothDevices: [],
notes: [],
startTime: nil
```
**Files to Update:**
- `02_IMPLEMENTATION_PLAN.md` - Phase 4 migration
- `03_DATABASE_SCHEMA.md` - player_state structure
- `01_ARCHITECTURE.md` - Update examples
**Time:** 1 hour
**Risk if skipped:** Minigame progress lost on page reload
---
### P1-2: Clarify Room Asset Loading (Issue #5)
**Problem:** Unclear how Tiled maps are served
**Action Required:**
1. Document that Tiled maps remain static assets
2. Clarify API returns game logic only
3. Update client integration example
**Files to Update:**
- `01_ARCHITECTURE.md` - API endpoint documentation
- `02_IMPLEMENTATION_PLAN_PART2.md` - Phase 9 client changes
**Time:** 2 hours
**Risk if skipped:** Confusion during implementation, potential rework
---
### P1-3: Add JSON Validation to ERB Processing
**Problem:** ERB errors could produce invalid JSON
**Action Required:**
```ruby
def load
# ... ERB processing ...
output = erb.result(binding_context.get_binding)
# Validate JSON
JSON.parse(output)
rescue JSON::ParserError => e
raise "Invalid JSON in #{scenario_name}: #{e.message}"
end
```
**Files to Update:**
- `02_IMPLEMENTATION_PLAN.md` - Phase 5 ScenarioLoader code
**Time:** 30 minutes
**Risk if skipped:** Hard-to-debug runtime errors
---
## Priority 2: Nice-to-Have Improvements (Enhancements)
These are optional improvements that would enhance the system.
### P2-1: Add Minigame Results API Endpoint
**Rationale:** Currently, minigame results are client-side only.
**Proposed Addition:**
```ruby
# POST /api/games/:id/minigame_result
def minigame_result
authorize @game_instance
minigame_name = params[:minigameName]
success = params[:success]
score = params[:score]
# Track in player_state
@game_instance.player_state['minigameResults'] ||= []
@game_instance.player_state['minigameResults'] << {
name: minigame_name,
success: success,
score: score,
timestamp: Time.current
}
@game_instance.save!
render json: { success: true }
end
```
**Benefits:**
- Track player performance
- Analytics on minigame difficulty
- Leaderboards possible
**Time:** 2 hours
---
### P2-2: Add Scenario Versioning
**Rationale:** Scenarios will evolve, need version tracking.
**Proposed Addition:**
```ruby
create_table :break_escape_scenarios do |t|
# ... existing fields ...
t.string :version, default: '1.0.0'
t.datetime :published_at
end
```
**Benefits:**
- Track scenario updates
- Support A/B testing
- Rollback capability
**Time:** 1 hour
---
### P2-3: Add Game Instance Snapshots
**Rationale:** Allow players to save/load game state.
**Proposed Addition:**
```ruby
create_table :break_escape_game_snapshots do |t|
t.references :game_instance
t.jsonb :snapshot_data
t.string :snapshot_type # auto, manual
t.timestamps
end
```
**Benefits:**
- Auto-save every N minutes
- Manual save points
- Recover from bugs
**Time:** 3 hours
---
### P2-4: Add Performance Monitoring
**Rationale:** Track API performance and errors.
**Proposed Addition:**
```ruby
# lib/break_escape/performance_monitor.rb
module BreakEscape
class PerformanceMonitor
def self.track(action_name)
start = Time.current
result = yield
duration = Time.current - start
Rails.logger.info "[BreakEscape] #{action_name} completed in #{duration}ms"
result
rescue => e
Rails.logger.error "[BreakEscape] #{action_name} failed: #{e.message}"
raise
end
end
end
# Usage in controllers:
def bootstrap
PerformanceMonitor.track('bootstrap') do
# ... existing code ...
end
end
```
**Benefits:**
- Identify slow endpoints
- Track error rates
- Production debugging
**Time:** 2 hours

## Priority 4: Testing Enhancements
### P4-1: Add Integration Test for Complete Flow
**Proposed Test:**
```ruby
# test/integration/break_escape/complete_game_flow_test.rb
class CompleteGameFlowTest < ActionDispatch::IntegrationTest
test "player can complete full scenario" do
user = users(:user)
sign_in user
# 1. Select scenario
get scenarios_path
assert_response :success
# 2. Start game
post scenario_path(scenarios(:ceo_exfil))
follow_redirect!
game = assigns(:game_instance)
# 3. Bootstrap

get api_game_bootstrap_path(game)
end
assert benchmark.real < 0.2, "Bootstrap took #{benchmark.real}s (>200ms)"
end
end
```
**Time:** 2 hours
---
## Implementation Priority Matrix
| Priority | Items | Total Time | Start When |
|----------|-------|------------|------------|
| **P0** | 3 items | ~10 hours | Before Phase 1 |
| **P1** | 3 items | ~3.5 hours | Before Phase 4 |
| **P2** | 4 items | ~8 hours | After Phase 12 (post-launch) |
| **P3** | 3 items | ~7 hours | Parallel with implementation |
| **P4** | 2 items | ~6 hours | Phase 10 (Testing) |
---

# Updated Database Schema (Corrected)
This document provides the corrected database schema that fixes Issue #2 (shared NPCs).
---
## Problem Statement
**Original Schema Issue:**
```ruby
create_table :break_escape_npc_scripts do |t|
t.references :scenario, null: false
t.string :npc_id, null: false
t.index [:scenario_id, :npc_id], unique: true # ← Forces 1:1 relationship
end
```
**Codebase Reality:**
- Many NPCs are shared across multiple scenarios
- `test-npc.json` used in 10+ scenarios
- `generic-npc.json`, hub NPCs are reusable
**Result:** Schema doesn't match actual usage patterns.
---
## Solution: Shared NPC Registry with Join Table
---
## Migration 1: NPC Scripts (Shared Registry)
```ruby
# db/migrate/xxx_create_break_escape_npc_scripts.rb
class CreateBreakEscapeNpcScripts < ActiveRecord::Migration[7.0]
def change
create_table :break_escape_npc_scripts do |t|
# Global NPC identifier (no scenario_id!)
t.string :npc_id, null: false
# Display information
t.string :display_name
t.string :avatar_path
# Ink scripts
t.text :ink_source # Optional .ink source
t.text :ink_compiled, null: false # Required .json compiled
# Metadata
t.string :npc_type # 'phone', 'person', 'generic'
t.jsonb :default_config # Default timedMessages, eventMappings
t.timestamps
end
# Global registry - each NPC appears once
add_index :break_escape_npc_scripts, :npc_id, unique: true
add_index :break_escape_npc_scripts, :npc_type
end
end
```
---
## Migration 2: Scenario-NPC Join Table
```ruby
# db/migrate/xxx_create_break_escape_scenario_npcs.rb
class CreateBreakEscapeScenarioNpcs < ActiveRecord::Migration[7.0]
def change
create_table :break_escape_scenario_npcs do |t|
# Foreign keys
t.references :scenario, null: false, foreign_key: { to_table: :break_escape_scenarios }
t.references :npc_script, null: false, foreign_key: { to_table: :break_escape_npc_scripts }
# Scenario-specific overrides (optional)
t.jsonb :config_overrides # Override timedMessages, eventMappings for this scenario
t.string :initial_knot # Starting dialogue knot for this scenario
t.string :room_id # Which room NPC appears in
t.timestamps
end
# Many-to-many: scenario can have many NPCs, NPC can be in many scenarios
add_index :break_escape_scenario_npcs, [:scenario_id, :npc_script_id], unique: true, name: 'index_scenario_npcs_unique'
add_index :break_escape_scenario_npcs, :room_id
end
end
```
---
## Migration 3: Scenarios (Unchanged)
```ruby
# db/migrate/xxx_create_break_escape_scenarios.rb
class CreateBreakEscapeScenarios < ActiveRecord::Migration[7.0]
def change
create_table :break_escape_scenarios do |t|
t.string :name, null: false
t.string :display_name, null: false
t.text :description
t.jsonb :scenario_data, null: false
t.boolean :published, default: false
t.integer :difficulty_level, default: 1
t.timestamps
end
add_index :break_escape_scenarios, :name, unique: true
add_index :break_escape_scenarios, :published
add_index :break_escape_scenarios, :scenario_data, using: :gin
end
end
```
---
## Migration 4: Game Instances (Extended)
```ruby
# db/migrate/xxx_create_break_escape_game_instances.rb

def change
create_table :break_escape_game_instances do |t|
# Polymorphic player
t.references :player, polymorphic: true, null: false
# Scenario reference
t.references :scenario, null: false, foreign_key: { to_table: :break_escape_scenarios }
# Player state (EXTENDED)
t.jsonb :player_state, null: false, default: {
currentRoom: nil,

## Benefits of Updated Schema
### ✅ Supports Shared NPCs
```ruby
# test-npc script exists once
npc = NpcScript.find_by(npc_id: 'test_npc')
# Used in multiple scenarios
npc.scenarios.count # => 10
```
### ✅ Reduces Database Size
- 30 unique NPCs vs 100+ duplicates
- Single update affects all scenarios
### ✅ Scenario-Specific Customization
```ruby
# Global NPC has default config
npc.default_config # => { phoneId: 'player_phone' }
# Scenario can override
scenario_npc.config_overrides # => { timedMessages: [...] }
scenario_npc.effective_config # => Merged config
```
### ✅ Complete Minigame State
```ruby
game.player_state['biometricSamples'] # Persisted ✓
game.player_state['bluetoothDevices'] # Persisted ✓
game.player_state['notes'] # Persisted ✓
```
---
## Migration from Old Schema (If Needed)
If implementation already started with old schema:
```ruby
# db/migrate/xxx_migrate_to_shared_npcs.rb
class MigrateToSharedNpcs < ActiveRecord::Migration[7.0]
def up
# 1. Create new tables
create_table :break_escape_npc_scripts_new do |t|
# ... new schema ...
end
create_table :break_escape_scenario_npcs do |t|
# ... join table ...
end
# 2. Migrate data
BreakEscape::NpcScript.find_each do |old_npc|
# Create global NPC if doesn't exist
new_npc = BreakEscape::NpcScript.find_or_create_by!(
npc_id: old_npc.npc_id,
ink_compiled: old_npc.ink_compiled
# ... other fields ...
)
# Create join table entry
BreakEscape::ScenarioNpc.create!(
scenario_id: old_npc.scenario_id,
npc_script_id: new_npc.id
)
end
# 3. Drop old table
drop_table :break_escape_npc_scripts_old
end
end
```
---
## Summary
**Changes:**
1. ✅ NPC scripts are now global (no scenario_id)
2. ✅ Join table links scenarios ↔ NPCs (many-to-many)
3. ✅ Scenario-specific overrides supported
4. ✅ Minigame state fields added to player_state
5. ✅ JSON validation in ScenarioLoader
**Files to Update:**
- `02_IMPLEMENTATION_PLAN.md` - Phase 4 migrations

# Rails Engine Migration Plan - Review 1
**Date:** November 20, 2025
**Status:** COMPLETE
**Recommendation:** Fix critical issues (P0) before implementation
---
## 📋 Review Overview
This review analyzes the Rails Engine migration plans in `planning_notes/rails-engine-migration-json/` and identifies critical issues that must be addressed before implementation begins.
**Overall Assessment:** MOSTLY SOLID - REQUIRES CORRECTIONS
The migration plan is well-structured and technically sound, but several critical discrepancies between the plan's assumptions and the actual codebase structure were discovered.

## 🚨 Critical Findings
### Blockers (Must Fix Before Phase 1)
1. **Ink File Structure Mismatch**
- Plan assumes `.ink.json` files
- Codebase uses `.json` files
- Only 3 of 30 NPCs have compiled scripts
- **Impact:** Phase 3 file reorganization will fail
2. **Missing Ink Compilation**
- No documented compilation process
- No tooling for compiling .ink → .json
- **Impact:** NPC scripts won't work
3. **Shared NPC Schema Issue**
- Schema forces 1:1 scenario-NPC relationship
- Codebase has many-to-many usage
- **Impact:** Seed script will fail or duplicate data
**Total Fix Time:** ~10 hours (1.25 days)
---
## ✅ Strengths of Current Plan
1. **JSON-Centric Approach** - Excellent fit for game state
2. **Minimal Client Changes** - <5% code change required
3. **Hacktivity Compatibility** - Thoroughly validated
4. **Phased Implementation** - Clear milestones
5. **Comprehensive Documentation** - 8 detailed guides
6. **Security** - CSP nonces, Pundit authorization
---
## 📊 Risk Assessment
**Without Fixes:**
- ❌ Implementation will fail at Phase 3
- ❌ Seed script will fail at Phase 5
- ❌ NPCs won't function (runtime errors)
- ❌ Minigame state will be lost
- ❌ Rework required: 3-5 days
**With Fixes:**
- ✅ Clean implementation
- ✅ No data loss
- ✅ No runtime errors
- ✅ Matches codebase reality
**Recommendation:** Fix P0 issues (10 hours) to save 3-5 days of rework

**Net Impact:** +1.5 days upfront, saves 3-5 days of rework
**Overall Timeline:** Still within 12-14 week estimate
---
## 🎓 Key Learnings
1. **Always validate assumptions** - Plan assumptions must match codebase reality
2. **Check file conventions** - Naming patterns matter (.json vs .ink.json)
3. **Schema must match usage** - Database relationships should reflect actual data patterns
4. **Compilation is critical** - Document tooling for generated files
5. **State must be complete** - Track all game state, not just core mechanics
