## 1. File Structure Issues

### 1.1 Splash Fallback Ext List Incomplete
- **File:** `index.html`
- **Line:** 770
- **Issue:** Splash fallback hardcodes 5 ext modules but `modules/ext/` directory has 8 files
- **Missing:** `mindmap.js`, `webdav.js`, `skill-pack-core.js`
- **Fix:**
  ```javascript
  // Before (5 modules)
  ['Extensions', ['calc.js','voice.js','cron.js','theme.js','wpm.js'], false]
  
  // After (8 modules)
  ['Extensions', ['calc.js','voice.js','cron.js','theme.js','wpm.js','mindmap.js','webdav.js','skill-pack-core.js'], false]
  ```

---

### 1.2 Preview Iframe Blocks JavaScript
- **File:** `index.html`
- **Line:** 684
- **Issue:** `<iframe sandbox="allow-same-origin">` missing `allow-scripts`
- **Impact:** HTML previews with JavaScript don't execute
- **Fix:**
  ```html
  <!-- Before -->
  <iframe sandbox="allow-same-origin"></iframe>
  
  <!-- After -->
  <iframe sandbox="allow-same-origin allow-scripts"></iframe>
  ```

---

### 1.3 Dead Code: EXT_FILES Array
- **File:** `module-loader.js`
- **Lines:** 35-37
- **Issue:** `EXT_FILES` array defined but never referenced (dead code, wrong count)
- **Impact:** Maintenance confusion, wrong module count (6 vs actual 8)
- **Fix:** Remove entirely — ext loading uses separate `extKeys` array on line 159

---

### 1.4 Packages.json URL Errors
- **File:** `packages.json`
- **Lines:** 7-167
- **Issues:**
  - All 18 package URLs point to `modules/<name>.js` (wrong path)
  - Actual files are in `modules/ext/<name>.js`
  - 12 packages reference files that don't exist anywhere
- **Impact:** WPM installs fail with 404 errors
- **Fix Options:**
  1. **Clean:** Remove 12 phantom packages, fix 6 real URLs to `modules/ext/`
  2. **Stub:** Create missing files in `modules/ext/`
- **Recommendation:** Option 1 (clean) — reduces bloat

---

### 1.5 Search Uses Intrusive Alert()
- **File:** `help.html`
- **Line:** 1149
- **Issue:** `alert('No results found')` blocks UI
- **Impact:** Poor UX, modal interruption
- **Fix:**
  ```javascript
  // Before
  if (!found) alert('No results found for: ' + query);
  
  // After
  if (!found) {
      const msg = document.getElementById('search-result-msg');
      if (msg) {
          msg.textContent = 'No results found for: ' + query;
          msg.style.display = 'block';
          setTimeout(() => { msg.style.display = 'none'; }, 3000);
      }
  }
  ```

## 2. Agent System Issues

### 2.1 Agent Loop Caps at 1 Turn (Not 5)
- **File:** `module-aiassist.js`
- **Lines:** 537-547
- **Issue:** When model returns text + tool_calls, agent executes tools then `return`s (exits loop)
- **Impact:** Agent stops after 1 tool turn instead of advertised `MAX_TOOL_TURNS = 5`
- **Root Cause:** Follow-up text-response block returns instead of continuing loop
- **Fix:**
  ```javascript
  // Before (lines 537-548)
  if (pendingText) {
      const followUp = await this.terminal.ollamaManager.chatWithTools(messages, []);
      if (followUp.message && followUp.message.content) {
          this.terminal.printAIResponse(followUp.message.content);
          return { finalAnswer: followUp.message.content, toolTurns }; // ← exits loop
      }
  }
  continue;
  
  // After
  if (pendingText) {
      messages.push({ role: 'assistant', content: pendingText });
  }
  continue; // ← loop continues, allows up to 5 turns
  ```

---

### 2.2 edit_module Not Checked as Destructive
- **File:** `module-aiassist.js`
- **Line:** 730
- **Issue:** `isDestructive()` doesn't include `edit_module` but system prompt (line 227) says it's `(DESTRUCTIVE)`
- **Impact:** AI told to ask permission but code never confirms
- **Fix:**
  ```javascript
  // Before
  isDestructive(name) {
      return name === 'write_file' || name === 'delete_file' || 
             name === 'run_command' || name === 'make_directory';
  }
  
  // After
  isDestructive(name) {
      return name === 'write_file' || name === 'delete_file' || 
             name === 'run_command' || name === 'make_directory' || 
             name === 'edit_module';
  }
  ```

---

### 2.3 Empty tools:[] Sent to Ollama
- **File:** `module-aiassist.js`
- **Line:** 539
- **Issue:** `chatWithTools(messages, [])` sends empty tools array
- **Impact:** Some Ollama models reject `tools: []`, triggers unnecessary fallback request
- **Fix:** Remove follow-up call; push text as `assistant` message then `continue` loop (see 2.1)

---

### 2.4 Default Model Blocks Auto-Selection
- **File:** `ollama-manager.js`
- **Lines:** 8, 42-45
- **Issue:** Default model `'gemma4:31b-cloud'` is truthy, so auto-selection skipped even if model doesn't exist
- **Impact:** Users get silent model errors until manually selecting
- **Fix:**
  ```javascript
  // Before (lines 42-45)
  if (!this.currentModel && this.models.length > 0) {
      this.currentModel = this.models[0].name;
      // ...
  }
  
  // After
  if (!this.currentModel || !this.models.some(m => m.name === this.currentModel)) {
      if (this.models.length > 0) {
          this.currentModel = this.models[0].name;
          // ...
      }
  }
  ```

---

### 2.5 abort() Misses chat() and chatStream()
- **File:** `ollama-manager.js`
- **Lines:** 70, 140, 176-183
- **Issue:** `_abortController` only set in `chatWithTools()` (line 195), not in `chat()` or `chatStream()`
- **Impact:** `ai-stop` command only cancels tool-calling requests, not direct chat or streaming
- **Fix:**
  ```javascript
  // Add to chat() method (around line 70)
  this._abortController = new AbortController();
  const signal = this._abortController.signal;
  const response = await fetch(`${this.endpoint}/api/generate`, {
      // ...
      signal
  });
  this._abortController = null;
  
  // Add to chatStream() method (around line 140) - same pattern
  ```

## 3. AI Routing Issues

### 3.1 Unknown Commands Not Awaited (executeCommand)
- **File:** `terminal.js`
- **Line:** 629
- **Issue:** `aiMod.chat([rawInput.trim()])` called without `await`
- **Impact:** Fire-and-forget execution, errors uncaught, no sequencing
- **Fix:**
  ```javascript
  // Before
  aiMod.chat([rawInput.trim()]);
  return;
  
  // After
  this.print('→ Routing to AI assistant...', 'info');
  await aiMod.chat([rawInput.trim()]);
  return;
  ```

---

### 3.2 Unknown Commands Not Awaited (dispatchCommand)
- **File:** `terminal.js`
- **Line:** 691
- **Issue:** Same as 3.1 but in `dispatchCommand()` (used for pipe chains)
- **Fix:** Same as 3.1

**Combined Impact:** Unknown commands like `hello` route to AI but without proper error handling or user feedback

---

## 4. Cache Invalidation

### 4.1 Cache Version Stale
- **File:** `module-loader.js`
- **Line:** 102
- **Issue:** `CACHE = '?v=17'` serves old cached modules
- **Impact:** Browser doesn't re-fetch updated module files
- **Fix:**
  ```javascript
  // Before
  const CACHE = '?v=17';
  
  // After
  const CACHE = '?v=18';
  ```
- **Note:** Requires users to hard refresh (Ctrl+F5 / Cmd+Shift+R)

---

## Implementation Priority

### High Priority (Critical Bugs)
1. **2.1** Agent loop caps at 1 turn — breaks multi-step AI tasks
2. **1.4** Packages.json 404 errors — WPM installs broken
3. **2.4** Default model blocks auto-selection — invisible failures
4. **2.5** abort() incomplete — `ai-stop` doesn't work for chat/stream

### Medium Priority (Functional Issues)
5. **1.1** Splash fallback incomplete — minor UX issue
6. **2.2** edit_module destructive check — security inconsistency
7. **3.1 + 3.2** AI routing without await — error handling gaps
8. **1.2** Preview iframe sandbox — JS previews broken

### Low Priority (Cleanup)
9. **1.3** Dead EXT_FILES code — maintenance clarity
10. **1.5** Search alert() → inline — UX polish
11. **4.1** Cache version — required after applying fixes

---

## Tradeoffs & Considerations

### Packages.json Cleanup (1.4)
- **Option A (Recommended):** Remove 12 phantom packages
  - ✅ Reduces bloat, cleaner codebase
  - ❌ Breaks backward compatibility if anyone installed them
- **Option B:** Create stub files for missing packages
  - ✅ Preserves compatibility
  - ❌ Adds dead weight, maintenance burden

### Agent Loop Change (2.1)
- Removing follow-up call changes message structure slightly
- Text+tool hybrid responses now push text as `assistant` message, then loop continues
- This is correct behavior but differs from original design

### AI Routing (3.1 + 3.2)
- Routing all unknown commands to AI may increase token usage
- Consider adding `ai-mode` toggle or `--no-ai` flag for opt-out

### Cache Version (4.1)
- Bumping version requires all users to hard refresh
- Consider adding release notes or announcement
