User correctly pointed out the loading UI was over-engineered.
## Simplifications:
### Before (over-complicated):
- Complex timeline management
- Success/failure flash effects (green/red)
- Spinner alternatives
- Stored references on sprites
- Timeline cleanup logic
- ~150 lines of code
### After (simple):
- startThrob(sprite) - Blue tint + pulsing alpha
- stopThrob(sprite) - Kill tweens, reset
- ~20 lines of code
## Why This Works:
1. **Door sprites get removed anyway** when they open
2. **Container items transition** to next state automatically
3. **Game already shows alerts** for success/error
4. **Only need feedback** during the ~100-300ms API call
## API Changes:
- showUnlockLoading() → startThrob()
- clearUnlockLoading() → stopThrob()
- No success/failure parameter needed
- No stored references to clean up
## Result:
From 150+ lines down to ~30 lines total.
Same UX, much simpler implementation.
User feedback: "Just set the door or item to throb, and remove when
the loading finishes (the door sprite is removed anyway), and if it's
a container, just follow the unlock with a removal of the animation."
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.
Based on comprehensive codebase review, enhanced implementation plans with:
## Phase 3 Updates (Scenario Conversion):
- Complete bash script to convert all 26 scenarios to ERB structure
- Explicit list of 3 main scenarios (ceo_exfil, cybok_heist, biometric_breach)
- List of 23 test/demo scenarios for development
- Instructions to rename .json to .erb (actual ERB code added later in Phase 4)
- Preserves git history with mv commands
- Both automated script and manual alternatives provided
## Phase 9 Updates (CSRF Token Handling):
NEW Section 9.3: "Setup CSRF Token Injection"
- Critical security implementation for Rails CSRF protection
- Complete view template with <%= form_authenticity_token %>
- JavaScript config injection via window.breakEscapeConfig
- CSRF token validation and error handling
- Browser console testing procedures
- 5 common CSRF issues with solutions
- Fallback to meta tag if config missing
- Development vs production considerations
## Phase 9 Updates (Async Unlock with Loading UI):
ENHANCED Section 9.5: "Update Unlock Validation with Loading UI"
- New file: unlock-loading-ui.js with Phaser.js throbbing tint effect
- showUnlockLoading(): Blue pulsing animation during server validation
- clearUnlockLoading(): Green flash on success, red flash on failure
- Alternative spinner implementation provided
- Complete unlockTarget() rewrite with async/await server validation
- Loading UI shows during API call (~100-300ms)
- Graceful error handling with user feedback
- Updates for ALL lock types: pin, password, key, lockpick, biometric, bluetooth, RFID
- Minigame callback updates to pass attempt and method to server
- Testing mode fallback (DISABLE_SERVER_VALIDATION)
- Preserves all existing unlock logic after server validation
## Key Features:
- Addresses 2 critical risks from review (CSRF tokens, async validation)
- Solves scenario conversion gap (26 files → ERB structure)
- Maintains backward compatibility during migration
- Comprehensive troubleshooting guidance
- Production-ready security implementation
Total additions: ~600 lines of detailed implementation guidance
Complete documentation for:
- 04_API_REFERENCE.md: All 9 API endpoints with examples

These complete the documentation set along with the Hacktivity integration guide.
Major simplification to migration plan:
- Remove NpcScript model entirely
- Reduce to 2 tables: missions (metadata) + games (state + scenario snapshot)
- Serve ink files directly from filesystem via game endpoints
- Move scenario_data to game instances (enables per-instance randomization)
- Eliminates Issue #2 (NPC schema complexity)
- Reduces P0 fixes from 10 hours to 2-3 hours
- Much simpler seed process (metadata only)
- Identify 5 critical issues requiring fixes before implementation
- Validate architecture decisions (mostly solid)
- Provide corrected database schema for shared NPCs
- Document P0 fixes needed: Ink compilation, file structure, NPC schema
- Recommend 1.5 days of prep work to save 3-5 days of rework
- Total review: 6 documents covering issues, architecture, and solutions

feat(combat): Integrate chair kicking with punch mechanic
Update chair interaction to use the punch system instead of direct kicking:
**Changes to interactions.js:**
- Modified swivel chair interaction to trigger player punch instead of
directly applying kick velocity
- Simplified chair interaction handler to just call playerCombat.punch()
**Changes to player-combat.js:**
- Extended checkForHits() to detect chairs in punch range and direction
- Added kickChair() method that applies the same velocity calculation:
- Calculates direction from player to chair
- Applies 1200 px/s kick force in that direction
- Triggers spin direction calculation for visual rotation
- Adds visual feedback (flash chair, light screen shake)
- Chairs now respond to punch AOE damage like hostile NPCs
Now clicking a chair or pressing 'E' near it triggers a punch, and if the
chair is in punch range and facing direction, it gets kicked with the
original velocity physics. Multiple chairs can be kicked with one punch.
feat(combat): Implement hostile NPC behavior and final integration (Phase 6-7)
Complete hostile NPC combat system with chase behavior and integration:
**Phase 6: Hostile NPC Behavior**
- Modified npc-behavior.js determineState() to check hostile state from npcHostileSystem
- Implemented updateHostileBehavior() with chase and attack logic:
- NPCs chase player when hostile and in aggro range
- NPCs stop and attack when in attack range
- NPCs use directional movement with proper animations
- Integration with npcCombat system for attack attempts
- Added KO state check to prevent KO'd NPCs from acting
**Phase 7: Final Integration**
- Modified player.js to disable movement when player is KO
- Added visual KO effect (50% alpha) to NPC sprites in npc-hostile.js
- Connected all combat systems end-to-end:
- Ink dialogue → hostile tag → hostile state → chase behavior → combat
- Player interaction → punch → NPC damage → KO → visual feedback
- NPC chase → attack → player damage → HP UI → game over
Full combat loop now functional: hostile NPCs chase and attack player,
player can punch hostile NPCs, complete visual/audio feedback, game over on KO.
feat(combat): Add feedback, UI, and combat mechanics (Phase 2-5)
Implement comprehensive combat feedback, UI, and mechanics:
**Phase 2: Enhanced Feedback Systems**
- damage-numbers.js: Floating damage numbers with object pooling
- screen-effects.js: Screen flash and shake for combat feedback
- sprite-effects.js: Sprite tinting, flashing, and visual effects
- attack-telegraph.js: Visual indicators for incoming NPC attacks
**Phase 3: UI Components**
- health-ui.js: Player health display as hearts (5 hearts, shows when damaged)
- npc-health-bars.js: Health bars above hostile NPCs with color coding
- game-over-screen.js: KO screen with restart/main menu options
**Phase 4-5: Combat Mechanics**
- player-combat.js: Player punch system with AOE directional damage
- npc-combat.js: NPC attack system with telegraph and cooldowns
- Modified interactions.js to trigger punch on hostile NPC interaction
- Integrated all systems into game.js create() and update() loops
Combat now functional with complete visual/audio feedback pipeline.
Player can punch hostile NPCs, NPCs can attack player, health tracking works.
feat(combat): Add hostile NPC system foundation (Phase 0-1)
Implement core hostile NPC combat system infrastructure:
- Add #hostile tag handler to chat-helpers.js for Ink integration
- Fix security-guard.ink to use proper hub pattern with -> hub instead of -> END
- Add #hostile:security_guard tags to hostile conversation paths
- Create combat configuration system (combat-config.js)
- Create combat event constants (combat-events.js)
- Implement player health tracking system with HP and KO state
- Implement NPC hostile state management with HP tracking
- Add combat debug utilities for testing
- Add error handling utilities for validation
- Integrate combat systems into game.js create() method
- Create test-hostile.ink for testing hostile tag system
This establishes the foundation for hostile NPC behavior, allowing NPCs to
become hostile through Ink dialogue and tracking health for both player and NPCs.
docs(npc): Apply codebase-verified corrections to hostile NPC plans
Apply critical corrections based on actual codebase verification:
CORRECTIONS.md (Updated):
- ✅ Confirms #exit_conversation tag ALREADY IMPLEMENTED
* Location: person-chat-minigame.js line 537
* No handler needed in chat-helpers.js
- ❌ Hostile tag still needs implementation in chat-helpers.js
- Provides exact code for hostile tag handler

- Updated action items to reflect what's already working
INTEGRATION_UPDATES.md (New):
- Comprehensive correction document
- Issue 1 Corrected: Exit conversation already works
- Issue 6 Corrected: Punch mechanics are interaction-based with AOE
- Details interaction-based punch targeting:
* Player clicks hostile NPC OR presses 'E' nearby
* Punch animation plays in facing direction
* Damage applies to ALL NPCs in range + direction (AOE)
* Can hit multiple enemies if grouped (strategic gameplay)
- Provides complete implementation examples
- Removes complexity of target selection systems
- Uses existing interaction patterns
quick_start.md (Updated):
- Removed exit_conversation handler (already exists)
- Updated hostile tag handler code

- Documents 4 important integration differences:
* Initialization in game.js not main.js
* Event dispatcher already exists (window.eventDispatcher)
* Room transition behavior needs design decision
* Multi-hostile NPC targeting needs design decision
- Confirms 8 systems are fully compatible with plan
- Provides existing code patterns to follow
- Corrects integration sequence
review2/quick_start.md:
- Step-by-step guide for Phase 0-1 implementation
- Includes complete code examples for critical systems
- Browser console test procedures
