# Test Harness Fixes - October 29, 2025

## Issues Resolved

### 1. Duplicate Class Declaration
**Error**: `Uncaught SyntaxError: Identifier 'InkEngine' has already been declared`

**Cause**: The `ink-engine.js` file had two `export class InkEngine` declarations - the minimal test version and a duplicate from planning code.

**Fix**: Removed the duplicate class declaration (lines 84-410) leaving only the minimal test-compatible InkEngine wrapper.

### 2. Script Load Order
**Error**: `window.InkEngine is not a constructor`

**Cause**: The module script was trying to call the `log()` function before it was defined in the subsequent script block.

**Fix**: Reorganized test-npc-ink.html script blocks:
1. Load ink.js library
2. Define helper functions (log, updateStatus)
3. Load ES modules and initialize systems
4. Define test functions

### 3. System Initialization
**Error**: Multiple "Cannot read properties of undefined" errors for npcEvents, npcManager, npcBarkSystem

**Cause**: The initialization code in the module block was running before the log function existed, preventing proper initialization and error reporting.

**Fix**: Moved the log function definition before the module imports, ensuring proper initialization order.

## Files Modified

### js/systems/ink/ink-engine.js
- Removed duplicate class declaration (lines 84-410)
- Kept only minimal InkEngine wrapper with methods: loadStory, continue, goToKnot, choose, getVariable, setVariable
- Properties: currentText, currentChoices

### test-npc-ink.html
- Reordered script blocks for proper initialization
- log() and updateStatus() now defined before module imports
- Module script can now safely call log() during initialization

## Current State

All modules now properly:
- Export default classes as expected by test harness
- Initialize without errors
- Have methods callable from test buttons

The test page should now:
- Load ink.js library ✓
- Initialize all NPC systems ✓
- Allow story loading and interaction ✓
- Support event emission and barks ✓
- Allow NPC registration ✓

## Next Steps

Test the page by:
1. Serve the repo: `python3 -m http.server 8000`
2. Open: http://localhost:8000/test-npc-ink.html
3. Click through test buttons in order
4. Verify console shows "✅ Systems initialized" on page load
5. Load test story and interact with it

If all tests pass, proceed to:
- Wire bark click → phone minigame integration
- Implement event cooldowns
- Add automatic event → knot mapping for NPCs
