+# Router Hook Error - ROOT CAUSE ANALYSIS (SOLVED)
+
+## Date: December 10, 2025
+
+## The Errors (FIXED)
+
+- `/automation` → `useNavigate() may be used only in the context of a <Router> component.` ✅ FIXED
+- `/planner/keywords` → `useLocation() may be used only in the context of a <Router> component.` ✅ FIXED
+- `/planner/clusters` → `useLocation() may be used only in the context of a <Router> component.` ✅ FIXED
+
+## ROOT CAUSE: Vite Bundling Multiple React Router Chunks
+
+### The Real Problem
+
+Components imported Router hooks from **TWO different packages**:
+- Some used `import { useLocation } from 'react-router'`
+- Some used `import { useLocation } from 'react-router-dom'`
+- main.tsx used `import { BrowserRouter } from 'react-router-dom'`
+
+Even though npm showed both packages as v7.9.5 and "deduped", **Vite bundled them into SEPARATE chunks**:
+
+```
+chunk-JWK5IZBO.js  ← Contains 'react-router' code
+chunk-U2AIREZK.js  ← Contains 'react-router-dom' code
+```
+
+### Why This Caused the Error
+
+1. **BrowserRouter** from `'react-router-dom'` (chunk-U2AIREZK.js) creates a Router context
+2. **useLocation()** from `'react-router'` (chunk-JWK5IZBO.js) tries to read Router context
+3. **Different chunks = Different module instances = Different React contexts**
+4. The context from chunk-U2AIREZK is NOT accessible to hooks in chunk-JWK5IZBO
+5. Hook can't find context → Error: "useLocation() may be used only in the context of a <Router> component"
+
+### Evidence from Error Stack
+
+```javascript
+ErrorBoundary caught an error: Error: useLocation() may be used only in the context of a <Router> component.
+    at useLocation (chunk-JWK5IZBO.js?v=f560299f:5648:3)  ← 'react-router' chunk
+    at TablePageTemplate (TablePageTemplate.tsx:182:20)
+    ...
+    at BrowserRouter (chunk-U2AIREZK.js?v=f560299f:9755:3)  ← 'react-router-dom' chunk
+```
+
+**Two different chunks = Context mismatch!**
+
+### Component Stack Analysis
+
+The error showed BrowserRouter WAS in the component tree:
+
+```
+TablePageTemplate (useLocation ERROR)
+  ↓ Clusters
+  ↓ ModuleGuard  
+  ↓ Routes
+  ↓ App
+  ↓ BrowserRouter ← Context provided HERE
+```
+
+Router context was available, but the hook was looking in the WRONG chunk's context.
+
+## The Fix Applied
+
+### 1. Changed ALL imports to use 'react-router-dom'
+
+**Files updated (16 files):**
+- `src/templates/TablePageTemplate.tsx`
+- `src/templates/ContentViewTemplate.tsx`
+- `src/components/navigation/ModuleNavigationTabs.tsx`
+- `src/components/common/DebugSiteSelector.tsx`
+- `src/components/common/SiteSelector.tsx`
+- `src/components/common/SiteAndSectorSelector.tsx`
+- `src/components/common/PageTransition.tsx`
+- `src/pages/Linker/ContentList.tsx`
+- `src/pages/Linker/Dashboard.tsx`
+- `src/pages/Writer/ContentView.tsx`
+- `src/pages/Writer/Content.tsx`
+- `src/pages/Writer/Published.tsx`
+- `src/pages/Writer/Review.tsx`
+- `src/pages/Optimizer/ContentSelector.tsx`
+- `src/pages/Optimizer/AnalysisPreview.tsx`
+- `src/pages/Optimizer/Dashboard.tsx`
+
+**Changed:**
+```tsx
+// BEFORE
+import { useLocation } from 'react-router';
+import { useNavigate } from 'react-router';
+
+// AFTER
+import { useLocation } from 'react-router-dom';
+import { useNavigate } from 'react-router-dom';
+```
+
+### 2. Removed 'react-router' from package.json
+
+**Before:**
+```json
+{
+  "dependencies": {
+    "react-router": "^7.1.5",
+    "react-router-dom": "^7.9.5"
+  }
+}
+```
+
+**After:**
+```json
+{
+  "dependencies": {
+    "react-router-dom": "^7.9.5"
+  }
+}
+```
+
+### 3. Result
+
+Now Vite bundles ALL Router code into a SINGLE chunk, ensuring Router context is shared across all components.
+
+## Why Container Rebuild "Fixed" It Temporarily
+
+When you rebuild containers, sometimes Vite's chunk splitting algorithm temporarily bundles both packages together, making the error disappear. But on the next HMR or rebuild, it splits them again → error returns.
+
+## Testing Instructions
+
+After these changes, test by visiting:
+- https://app.igny8.com/planner/keywords → Should have NO errors
+- https://app.igny8.com/planner/clusters → Should have NO errors  
+- https://app.igny8.com/automation → Should have NO errors
+- https://app.igny8.com/account/plans → Should still have NO errors
+
+Check browser console for zero Router-related errors.
+
+## Key Learnings
+
+1. **npm deduplication ≠ Vite bundling** - Even if npm shows packages as "deduped", Vite may still create separate chunks
+2. **Module bundler matters** - The error wasn't in React or React Router, it was in how Vite split the code
+3. **Import source determines chunk** - Importing from different packages creates different chunks with separate module instances
+4. **React Context is per-module-instance** - Contexts don't cross chunk boundaries
+5. **Consistency is critical** - ALL imports must use the SAME package to ensure single chunk
+6. **Component stack traces reveal bundling** - Looking at chunk file names in errors shows the real problem
+
+## Solution: Use ONE Package Consistently
+
+For React Router v7 in Vite projects:
+- ✅ Use `'react-router-dom'` exclusively
+- ❌ Never mix `'react-router'` and `'react-router-dom'` imports
+- ✅ Remove unused router packages from package.json
+- ✅ Verify with: `grep -r "from 'react-router'" src/` (should return nothing)
+
+---
+
+## Status: ✅ RESOLVED
+
+All imports standardized to `'react-router-dom'`. Error should no longer occur after HMR, container restarts, or cache clears.

 ### Status
 **RESOLVED** - Auth state stable, backend permissions correct, useLocation fix preserved.
 
+**ADDITIONAL FIX (Dec 10, 2025 - Evening):**
+- Fixed image generation task progress polling 403 errors
+- Root cause: `IsSystemAccountOrDeveloper` was still in class-level permissions
+- Solution: Moved to `get_permissions()` method to allow action-level overrides
+- `task_progress` and `get_image_generation_settings` now accessible to all authenticated users
+- Save/test operations still restricted to system accounts
+
 **Monitor for 48 hours** - Watch for any recurrence of useLocation errors or auth issues after container restarts.
