 # Agent Context Hints
 
+## Current Status
+Currently mid migration from go templates (`./templates`) to React App (`./frontend`)
+
 ## Architecture Context
 - **Backend**: Go with Gin router (legacy), SQLC for database queries, currently migrating to V1 API (oapi-codegen)
 - **Frontend**: React with Vite, currently migrating from Go templates (using the V1 API)
@@ -32,3 +35,25 @@
 - API implementation may not map all fields from DB query (check `api/v1/activity.go` mapping)
 - `start_time` is `interface{}` in Go models, needs type assertion
 - Go templates use `LOCAL_TIME()` SQL function for timezone-aware display
+
+## CRITICAL: Migration Implementation Rules
+- **NEVER write ad-hoc SQL queries** - All database access must use existing SQLC queries from `database/query.sql`
+- **Mirror legacy implementation** - Check `api/app-admin-routes.go`, `api/app-routes.go` for existing business logic
+- **Reuse existing functions** - Look for helper functions in `api/utils.go` that handle file operations, metadata, etc.
+- **SQLC query reference** - Check `database/query.sql` for available queries and `database/query.sql.go` for function signatures
+- **When implementing TODOs in v1 API**:
+  1. Find the corresponding function in legacy API (e.g., `api/app-admin-routes.go`)
+  2. Copy the logic pattern but adapt to use `s.db.Queries.*` instead of `api.db.Queries.*`
+  3. Use existing helper functions from `api/utils.go` (make them accessible if needed)
+  4. Map legacy response types to new v1 API response types
+  5. Never create new database queries - use what SQLC already provides
+
+## API Structure
+- **Legacy API**: `api/` directory (e.g., `api/app-admin-routes.go`, `api/app-routes.go`)
+  - Uses Gin router
+  - Renders Go templates
+  - Contains all existing business logic to mirror
+- **V1 API**: `api/v1/` directory (e.g., `api/v1/admin.go`, `api/v1/documents.go`)
+  - Uses oapi-codegen (OpenAPI spec driven)
+  - Returns JSON responses
+  - Currently being migrated from legacy patterns

+# API V1 Admin vs Legacy Implementation Comparison
+
+## Overview
+This document compares the V1 API admin implementations with the legacy API implementations to identify deviations and ensure adequate information is returned for the React app.
+
+---
+
+## 1. GET /admin
+
+### V1 Implementation
+- Returns: `GetAdmin200JSONResponse` with `DatabaseInfo`
+- DatabaseInfo contains: `documentsSize`, `activitySize`, `progressSize`, `devicesSize`
+- Gets documents count from `GetDocumentsSize(nil)`
+- Aggregates activity/progress/devices across all users using `GetDatabaseInfo`
+
+### Legacy Implementation
+- Function: `appGetAdmin`
+- Returns: HTML template page
+- No direct database info returned in endpoint
+- Template uses base template variables
+
+### Deviations
+**None** - V1 provides more detailed information which is beneficial for React app
+
+### React App Requirements
+✅ **Sufficient** - V1 returns all database statistics needed for admin dashboard
+
+---
+
+## 2. POST /admin (Admin Actions)
+
+### V1 Implementation
+- Actions: `BACKUP`, `RESTORE`, `CACHE_TABLES`, `METADATA_MATCH`
+- Returns: `PostAdminAction200ApplicationoctetStreamResponse` with Body as io.Reader
+- BACKUP: Streams ZIP file via pipe
+- RESTORE: Returns success message as stream
+- CACHE_TABLES: Returns confirmation message as stream
+- METADATA_MATCH: Returns not implemented message as stream
+
+### Legacy Implementation
+- Function: `appPerformAdminAction`
+- Actions: Same as V1
+- BACKUP: Streams ZIP with proper Content-Disposition header
+- RESTORE: After restore, redirects to `/login`
+- CACHE_TABLES: Runs async, returns to admin page
+- METADATA_MATCH: TODO (not implemented)
+
+### Deviations
+1. **RESTORE Response**: V1 returns success message, legacy redirects to login
+   - **Impact**: React app won't be redirected, but will get success confirmation
+   - **Recommendation**: Consider adding redirect URL in response for React to handle
+
+2. **CACHE_TABLES Response**: V1 returns stream, legacy returns to admin page
+   - **Impact**: Different response format but both provide confirmation
+   - **Recommendation**: Acceptable for REST API
+
+3. **METADATA_MATCH Response**: Both not implemented
+   - **Impact**: None
+
+### React App Requirements
+✅ **Sufficient** - V1 returns confirmation messages for all actions
+⚠️ **Consideration**: RESTORE doesn't redirect - React app will need to handle auth state
+
+---
+
+## 3. GET /admin/users
+
+### V1 Implementation
+- Returns: `GetUsers200JSONResponse` with array of `User` objects
+- User object fields: `Id`, `Admin`, `CreatedAt`
+- Data from: `s.db.Queries.GetUsers(ctx)`
+
+### Legacy Implementation
+- Function: `appGetAdminUsers`
+- Returns: HTML template with user data
+- Template variables available: `.Data` contains all user fields
+- User fields from DB: `ID`, `Pass`, `AuthHash`, `Admin`, `Timezone`, `CreatedAt`
+- Template only uses: `$user.ID`, `$user.Admin`, `$user.CreatedAt`
+
+### Deviations
+**None** - V1 returns exactly the fields used by the legacy template
+
+### React App Requirements
+✅ **Sufficient** - All fields used by legacy admin users page are included
+
+---
+
+## 4. POST /admin/users (User CRUD)
+
+### V1 Implementation
+- Operations: `CREATE`, `UPDATE`, `DELETE`
+- Returns: `UpdateUser200JSONResponse` with updated users list
+- Validation:
+  - User cannot be empty
+  - Password required for CREATE
+  - Something to update for UPDATE
+  - Last admin protection for DELETE and UPDATE
+- Same business logic as legacy
+
+### Legacy Implementation
+- Function: `appUpdateAdminUsers`
+- Operations: Same as V1
+- Returns: HTML template with updated user list
+- Same validation and business logic
+
+### Deviations
+**None** - V1 mirrors legacy business logic exactly
+
+### React App Requirements
+✅ **Sufficient** - V1 returns updated users list after operation
+
+---
+
+## 5. GET /admin/import
+
+### V1 Implementation
+- Parameters: `directory` (optional), `select` (optional)
+- Returns: `GetImportDirectory200JSONResponse`
+- Response fields: `CurrentPath`, `Items` (array of `DirectoryItem`)
+- DirectoryItem fields: `Name`, `Path`
+- Default path: `s.cfg.DataPath` if no directory specified
+- If `select` parameter set, returns empty items with selected path
+
+### Legacy Implementation
+- Function: `appGetAdminImport`
+- Parameters: Same as V1
+- Returns: HTML template
+- Template variables: `.CurrentPath`, `.Data` (array of directory names)
+- Same default path logic
+
+### Deviations
+1. **DirectoryItem structure**: V1 includes `Path` field, legacy only uses names
+   - **Impact**: V1 provides more information (beneficial for React)
+   - **Recommendation**: Acceptable improvement
+
+### React App Requirements
+✅ **Sufficient** - V1 provides all information plus additional path data
+
+---
+
+## 6. POST /admin/import
+
+### V1 Implementation
+- Parameters: `directory`, `type` (DIRECT or COPY)
+- Returns: `PostImport200JSONResponse` with `ImportResult` array
+- ImportResult fields: `Id`, `Name`, `Path`, `Status`, `Error`
+- Status values: `SUCCESS`, `EXISTS`, `FAILED`
+- Same transaction and error handling as legacy
+- Results sorted by status priority
+
+### Legacy Implementation
+- Function: `appPerformAdminImport`
+- Parameters: Same as V1
+- Returns: HTML template with results (redirects to import-results page)
+- Result fields: `ID`, `Name`, `Path`, `Status`, `Error`
+- Same status values and priority
+
+### Deviations
+**None** - V1 mirrors legacy exactly
+
+### React App Requirements
+✅ **Sufficient** - All import result information included
+
+---
+
+## 7. GET /admin/import-results
+
+### V1 Implementation
+- Returns: `GetImportResults200JSONResponse` with empty `ImportResult` array
+- Note: Results returned immediately after import in POST /admin/import
+- Legacy behavior: Results displayed on separate page after POST
+
+### Legacy Implementation
+- No separate endpoint
+- Results shown on `page/admin-import-results` template after POST redirect
+
+### Deviations
+1. **Endpoint Purpose**: Legacy doesn't have this endpoint
+   - **Impact**: V1 endpoint returns empty results
+   - **Recommendation**: Consider storing results in session/memory for retrieval
+   - **Alternative**: React app can cache results from POST response
+
+### React App Requirements
+⚠️ **Limited** - Endpoint returns empty, React app should cache POST results
+💡 **Suggestion**: Enhance to store/retrieve results from session or memory
+
+---
+
+## 8. GET /admin/logs
+
+### V1 Implementation
+- Parameters: `filter` (optional)
+- Returns: `GetLogs200JSONResponse` with `Logs` and `Filter`
+- Log lines: Pretty-printed JSON with indentation
+- Supports JQ filters for complex filtering
+- Supports basic string filters (quoted)
+- Filters only pretty JSON lines
+
+### Legacy Implementation
+- Function: `appGetAdminLogs`
+- Parameters: Same as V1
+- Returns: HTML template with filtered logs
+- Same JQ and basic filter logic
+- Template variables: `.Data` (log lines), `.Filter`
+
+### Deviations
+**None** - V1 mirrors legacy exactly
+
+### React App Requirements
+✅ **Sufficient** - All log information and filtering capabilities included
+
+---
+
+## Summary of Deviations
+
+### Critical (Requires Action)
+None identified
+
+### Important (Consideration)
+1. **RESTORE redirect**: Legacy redirects to login after restore, V1 doesn't
+   - **Impact**: React app won't automatically redirect
+   - **Recommendation**: Add `redirect_url` field to response or document expected behavior
+
+2. **Import-results endpoint**: Returns empty results
+   - **Impact**: Cannot retrieve previous import results
+   - **Recommendation**: Store results in session/memory or cache on client side
+
+### Minor (Acceptable Differences)
+1. **DirectoryItem includes Path**: V1 includes path field
+   - **Impact**: Additional information available
+   - **Recommendation**: Acceptable improvement
+
+2. **Response formats**: V1 returns JSON, legacy returns HTML
+   - **Impact**: Expected for REST API migration
+   - **Recommendation**: Acceptable
+
+### No Deviations
+- GET /admin (actually provides MORE info)
+- GET /admin/users
+- POST /admin/users
+- POST /admin/import
+- GET /admin/logs
+
+---
+
+## Database Access Compliance
+
+✅ **All database access uses existing SQLC queries**
+- `GetDocumentsSize` - Document count
+- `GetUsers` - User list
+- `GetDatabaseInfo` - Per-user stats
+- `CreateUser` - User creation
+- `UpdateUser` - User updates
+- `DeleteUser` - User deletion
+- `GetUser` - Single user retrieval
+- `GetDocument` - Document lookup
+- `UpsertDocument` - Document upsert
+- `CacheTempTables` - Table caching
+- `Reload` - Database reload
+
+❌ **No ad-hoc SQL queries used**
+
+---
+
+## Business Logic Compliance
+
+✅ **All critical business logic mirrors legacy**
+- User validation (empty user, password requirements)
+- Last admin protection
+- Transaction handling for imports
+- Backup/restore validation and flow
+- Auth hash rotation after restore
+- Log filtering with JQ support
+
+---
+
+## Recommendations for React App
+
+1. **Handle restore redirect**: After successful restore, redirect to login page
+2. **Cache import results**: Store POST import results for display
+3. **Leverage additional data**: Use `Path` field in DirectoryItem for better UX
+4. **Error handling**: All error responses follow consistent pattern with message
+
+---
+
+## Conclusion
+
+The V1 API admin implementations successfully mirror the legacy implementations with:
+- ✅ All required data fields for React app
+- ✅ Same business logic and validation
+- ✅ Proper use of existing SQLC queries
+- ✅ No critical deviations
+
+Minor improvements and acceptable RESTful patterns:
+- Additional data fields (DirectoryItem.Path)
+- RESTful JSON responses instead of HTML
+- Confirmation messages for async operations
+
+**Status**: Ready for React app integration

+# Toast Migration Analysis
+
+This document identifies all places in the app where toast notifications should replace existing error handling mechanisms.
+
+## Summary
+
+**Total Locations Identified**: 7 pages/components  
+**Current Error Handling Methods**:
+- `alert()` - Used in 3 locations (5+ instances)
+- Inline error/success messages - Used in 2 locations
+- Form input validation messages - Used in 1 location
+- No error handling (TODO) - Used in 1 location
+
+---
+
+## Detailed Analysis
+
+### 1. AdminPage.tsx ⚠️ HIGH PRIORITY
+
+**File**: `src/pages/AdminPage.tsx`
+
+**Current Implementation**:
+```typescript
+const [message, setMessage] = useState<string | null>(null);
+const [errorMessage, setErrorMessage] = useState<string | null>(null);
+
+// Multiple handlers use inline state
+onSuccess: () => {
+  setMessage('Backup completed successfully');
+  setErrorMessage(null);
+},
+onError: (error) => {
+  setErrorMessage('Backup failed: ' + (error as any).message);
+  setMessage(null);
+},
+
+// Rendered inline in JSX
+{errorMessage && (
+  <span className="text-red-400 text-xs">{errorMessage}</span>
+)}
+{message && (
+  <span className="text-green-400 text-xs">{message}</span>
+)}
+```
+
+**Affected Actions**:
+- `handleBackupSubmit` - Backup operation
+- `handleRestoreSubmit` - Restore operation  
+- `handleMetadataMatch` - Metadata matching
+- `handleCacheTables` - Cache tables
+
+**Recommended Migration**:
+```typescript
+import { useToasts } from '../components';
+
+const { showInfo, showError } = useToasts();
+
+onSuccess: () => {
+  showInfo('Backup completed successfully');
+},
+onError: (error) => {
+  showError('Backup failed: ' + (error as any).message);
+},
+
+// Remove these from JSX:
+// - {errorMessage && <span className="text-red-400 text-xs">{errorMessage}</span>}
+// - {message && <span className="text-green-400 text-xs">{message}</span>}
+// Remove state variables:
+// - const [message, setMessage] = useState<string | null>(null);
+// - const [errorMessage, setErrorMessage] = useState<string | null>(null);
+```
+
+**Impact**: HIGH - 4 API operations with error/success feedback
+
+---
+
+### 2. AdminUsersPage.tsx ⚠️ HIGH PRIORITY
+
+**File**: `src/pages/AdminUsersPage.tsx`
+
+**Current Implementation**:
+```typescript
+// 4 instances of alert() calls
+onError: (error: any) => {
+  alert('Failed to create user: ' + error.message);
+},
+// ... similar for delete, update password, update admin status
+```
+
+**Affected Operations**:
+- User creation (line ~55)
+- User deletion (line ~69)
+- Password update (line ~85)
+- Admin status toggle (line ~101)
+
+**Recommended Migration**:
+```typescript
+import { useToasts } from '../components';
+
+const { showInfo, showError } = useToasts();
+
+onSuccess: () => {
+  showInfo('User created successfully');
+  setShowAddForm(false);
+  setNewUsername('');
+  setNewPassword('');
+  setNewIsAdmin(false);
+  refetch();
+},
+onError: (error: any) => {
+  showError('Failed to create user: ' + error.message);
+},
+
+// Similar pattern for other operations
+```
+
+**Impact**: HIGH - Critical user management operations
+
+---
+
+### 3. AdminImportPage.tsx ⚠️ HIGH PRIORITY
+
+**File**: `src/pages/AdminImportPage.tsx`
+
+**Current Implementation**:
+```typescript
+onError: (error) => {
+  console.error('Import failed:', error);
+  alert('Import failed: ' + (error as any).message);
+},
+
+// No success toast - just redirects
+onSuccess: (response) => {
+  console.log('Import completed:', response.data);
+  window.location.href = '/admin/import-results';
+},
+```
+
+**Recommended Migration**:
+```typescript
+import { useToasts } from '../components';
+
+const { showInfo, showError } = useToasts();
+
+onSuccess: (response) => {
+  showInfo('Import completed successfully');
+  setTimeout(() => {
+    window.location.href = '/admin/import-results';
+  }, 1500);
+},
+onError: (error) => {
+  showError('Import failed: ' + (error as any).message);
+},
+```
+
+**Impact**: HIGH - Long-running import operation needs user feedback
+
+---
+
+### 4. SettingsPage.tsx ⚠️ MEDIUM PRIORITY (TODO)
+
+**File**: `src/pages/SettingsPage.tsx`
+
+**Current Implementation**:
+```typescript
+const handlePasswordSubmit = (e: FormEvent) => {
+  e.preventDefault();
+  // TODO: Call API to change password
+};
+
+const handleTimezoneSubmit = (e: FormEvent) => {
+  e.preventDefault();
+  // TODO: Call API to change timezone
+};
+```
+
+**Recommended Migration** (when API calls are implemented):
+```typescript
+import { useToasts } from '../components';
+import { useUpdatePassword, useUpdateTimezone } from '../generated/anthoLumeAPIV1';
+
+const { showInfo, showError } = useToasts();
+const updatePassword = useUpdatePassword();
+const updateTimezone = useUpdateTimezone();
+
+const handlePasswordSubmit = async (e: FormEvent) => {
+  e.preventDefault();
+  try {
+    await updatePassword.mutateAsync({
+      data: { password, newPassword }
+    });
+    showInfo('Password updated successfully');
+    setPassword('');
+    setNewPassword('');
+  } catch (error: any) {
+    showError('Failed to update password: ' + error.message);
+  }
+};
+
+const handleTimezoneSubmit = async (e: FormEvent) => {
+  e.preventDefault();
+  try {
+    await updateTimezone.mutateAsync({
+      data: { timezone }
+    });
+    showInfo('Timezone updated successfully');
+  } catch (error: any) {
+    showError('Failed to update timezone: ' + error.message);
+  }
+};
+```
+
+**Impact**: MEDIUM - User-facing settings need feedback when implemented
+
+---
+
+### 5. LoginPage.tsx ⚠️ MEDIUM PRIORITY
+
+**File**: `src/pages/LoginPage.tsx`
+
+**Current Implementation**:
+```typescript
+const [error, setError] = useState('');
+
+const handleSubmit = async (e: FormEvent) => {
+  // ...
+  try {
+    await login(username, password);
+  } catch (err) {
+    setError('Invalid credentials');
+  }
+  // ...
+};
+
+// Rendered inline under password input
+<span className="absolute -bottom-5 text-red-400 text-xs">{error}</span>
+```
+
+**Recommended Migration**:
+```typescript
+import { useToasts } from '../components';
+
+const { showError } = useToasts();
+
+const handleSubmit = async (e: FormEvent) => {
+  e.preventDefault();
+  setIsLoading(true);
+
+  try {
+    await login(username, password);
+  } catch (err) {
+    showError('Invalid credentials');
+  } finally {
+    setIsLoading(false);
+  }
+};
+
+// Remove from JSX:
+// - <span className="absolute -bottom-5 text-red-400 text-xs">{error}</span>
+// Remove state:
+// - const [error, setError] = useState('');
+```
+
+**Impact**: MEDIUM - Login errors are important but less frequent
+
+---
+
+### 6. DocumentsPage.tsx ⚠️ LOW PRIORITY
+
+**File**: `src/pages/DocumentsPage.tsx`
+
+**Current Implementation**:
+```typescript
+const handleFileChange = async (e: React.ChangeEvent<HTMLInputElement>) => {
+  const file = e.target.files?.[0];
+  if (!file) return;
+
+  if (!file.name.endsWith('.epub')) {
+    alert('Please upload an EPUB file');
+    return;
+  }
+
+  try {
+    await createMutation.mutateAsync({
+      data: { document_file: file }
+    });
+    alert('Document uploaded successfully!');
+    setUploadMode(false);
+    refetch();
+  } catch (error) {
+    console.error('Upload failed:', error);
+    alert('Failed to upload document');
+  }
+};
+```
+
+**Recommended Migration**:
+```typescript
+import { useToasts } from '../components';
+
+const { showInfo, showWarning, showError } = useToasts();
+
+const handleFileChange = async (e: React.ChangeEvent<HTMLInputElement>) => {
+  const file = e.target.files?.[0];
+  if (!file) return;
+
+  if (!file.name.endsWith('.epub')) {
+    showWarning('Please upload an EPUB file');
+    return;
+  }
+
+  try {
+    await createMutation.mutateAsync({
+      data: { document_file: file }
+    });
+    showInfo('Document uploaded successfully!');
+    setUploadMode(false);
+    refetch();
+  } catch (error: any) {
+    showError('Failed to upload document: ' + error.message);
+  }
+};
+```
+
+**Impact**: LOW - Upload errors are less frequent, but good UX to have toasts
+
+---
+
+### 7. authInterceptor.ts ⚠️ OPTIONAL ENHANCEMENT
+
+**File**: `src/auth/authInterceptor.ts`
+
+**Current Implementation**:
+```typescript
+// Response interceptor to handle auth errors
+axios.interceptors.response.use(
+  (response) => {
+    return response;
+  },
+  (error) => {
+    if (error.response?.status === 401) {
+      // Clear token on auth failure
+      localStorage.removeItem(TOKEN_KEY);
+      // Optionally redirect to login
+      // window.location.href = '/login';
+    }
+    return Promise.reject(error);
+  }
+);
+```
+
+**Recommended Enhancement**:
+```typescript
+// Add a global error handler for 401 errors
+// Note: This would need access to a toast context outside React
+// Could be implemented via a global toast service or event system
+
+axios.interceptors.response.use(
+  (response) => {
+    return response;
+  },
+  (error) => {
+    if (error.response?.status === 401) {
+      localStorage.removeItem(TOKEN_KEY);
+      // Could dispatch a global event here to show toast
+      window.dispatchEvent(new CustomEvent('auth-error', { 
+        detail: { message: 'Session expired. Please log in again.' } 
+      }));
+    } else if (error.response?.status >= 500) {
+      // Show toast for server errors
+      window.dispatchEvent(new CustomEvent('api-error', { 
+        detail: { message: 'Server error. Please try again later.' } 
+      }));
+    }
+    return Promise.reject(error);
+  }
+);
+```
+
+**Note**: This would require a global toast service or event system. More complex to implement.
+
+**Impact**: LOW - Optional enhancement for global error handling
+
+---
+
+## Priority Matrix
+
+| Page | Priority | Complexity | Impact | Instances |
+|------|----------|------------|--------|-----------|
+| AdminPage.tsx | HIGH | LOW | HIGH | 4 actions |
+| AdminUsersPage.tsx | HIGH | LOW | HIGH | 4 alerts |
+| AdminImportPage.tsx | HIGH | LOW | HIGH | 1 alert |
+| SettingsPage.tsx | MEDIUM | MEDIUM | MEDIUM | 2 TODOs |
+| LoginPage.tsx | MEDIUM | LOW | MEDIUM | 1 error |
+| DocumentsPage.tsx | LOW | LOW | LOW | 2 alerts |
+| authInterceptor.ts | OPTIONAL | HIGH | LOW | N/A |
+
+---
+
+## Implementation Plan
+
+### Phase 1: Quick Wins (1-2 hours)
+1. **AdminPage.tsx** - Replace inline messages with toasts
+2. **AdminUsersPage.tsx** - Replace all `alert()` calls
+3. **AdminImportPage.tsx** - Replace `alert()` and add success toast
+
+### Phase 2: Standard Migration (1 hour)
+4. **LoginPage.tsx** - Replace inline error with toast
+5. **DocumentsPage.tsx** - Replace `alert()` calls
+
+### Phase 3: Future Implementation (when ready)
+6. **SettingsPage.tsx** - Add toasts when API calls are implemented
+
+### Phase 4: Optional Enhancement (if needed)
+7. **authInterceptor.ts** - Global error handling with toasts
+
+---
+
+## Benefits of Migration
+
+### User Experience
+- ✅ Consistent error messaging across the app
+- ✅ Less intrusive than `alert()` dialogs
+- ✅ Auto-dismissing notifications (no need to click to dismiss)
+- ✅ Better mobile experience (no modal blocking the UI)
+- ✅ Stackable notifications for multiple events
+
+### Developer Experience
+- ✅ Remove state management for error/success messages
+- ✅ Cleaner, more maintainable code
+- ✅ Consistent API for showing notifications
+- ✅ Theme-aware styling (automatic dark/light mode support)
+
+### Code Quality
+- ✅ Remove `alert()` calls (considered an anti-pattern in modern web apps)
+- ✅ Remove inline error message rendering
+- ✅ Follow React best practices
+- ✅ Reduce component complexity
+
+---
+
+## Testing Checklist
+
+After migrating each page, verify:
+- [ ] Error toasts display correctly on API failures
+- [ ] Success toasts display correctly on successful operations
+- [ ] Toasts appear in top-right corner
+- [ ] Toasts auto-dismiss after the specified duration
+- [ ] Toasts can be manually dismissed via X button
+- [ ] Multiple toasts stack correctly
+- [ ] Theme colors are correct in light mode
+- [ ] Theme colors are correct in dark mode
+- [ ] No console errors related to toast functionality
+- [ ] Previous functionality still works (e.g., redirects after success)
+
+---
+
+## Estimated Effort
+
+| Phase | Pages | Time Estimate |
+|-------|-------|---------------|
+| Phase 1 | AdminPage, AdminUsersPage, AdminImportPage | 1-2 hours |
+| Phase 2 | LoginPage, DocumentsPage | 1 hour |
+| Phase 3 | SettingsPage (when API ready) | 30 minutes |
+| Phase 4 | authInterceptor (optional) | 1-2 hours |
+| **Total** | **7 pages** | **3-5 hours** |
+
+---
+
+## Notes
+
+1. **SettingsPage**: API calls are not yet implemented (TODOs). Should migrate when those are added.
+
+2. **authInterceptor**: Global error handling would require a different approach, possibly a global event system or toast service outside React context.
+
+3. **Redirect behavior**: Some operations (like AdminImportPage) redirect on success. Consider showing a toast first, then redirecting after a short delay for better UX.
+
+4. **Validation messages**: Some pages have inline validation messages (like "Please upload an EPUB file"). These could remain inline or be shown as warning toasts - consider UX tradeoffs.
+
+5. **Loading states**: Ensure loading states are still displayed appropriately alongside toasts.
+
+6. **Refetch behavior**: Pages that call `refetch()` after successful mutations should continue to do so; toasts are additive, not replacement for data refresh.

+
+---
+
+## Backend API Changes
+
+### New Endpoint: `PUT /api/v1/settings`
+
+**Request Body:**
+```json
+{
+  "password": "current_password",      // Required when setting new_password
+  "new_password": "new_secure_pass",  // Optional
+  "timezone": "America/New_York"      // Optional
+}
+```
+
+**Response:** `200 OK` - Returns full `SettingsResponse`
+
+**Error Responses:**
+- `400 Bad Request` - Invalid request (missing fields, invalid password)
+- `401 Unauthorized` - Not authenticated
+- `500 Internal Server Error` - Server error
+
+**Usage Examples:**
+
+1. Update password:
+```bash
+curl -X PUT http://localhost:8080/api/v1/settings \
+  -H "Content-Type: application/json" \
+  -H "Cookie: session=..." \
+  -d '{"password":"oldpass","new_password":"newpass"}'
+```
+
+2. Update timezone:
+```bash
+curl -X PUT http://localhost:8080/api/v1/settings \
+  -H "Content-Type: application/json" \
+  -H "Cookie: session=..." \
+  -d '{"timezone":"America/New_York"}'
+```
+
+3. Update both:
+```bash
+curl -X PUT http://localhost:8080/api/v1/settings \
+  -H "Content-Type: application/json" \
+  -H "Cookie: session=..." \
+  -d '{"password":"oldpass","new_password":"newpass","timezone":"America/New_York"}'
+```
+
+---
+
+## Frontend API Changes
+
+### New Generated Function: `useUpdateSettings`

+
+const updateSettings = useUpdateSettings();
+```
+
+**Usage:**
+```typescript
+await updateSettings.mutateAsync({
+  data: {
+    password: 'current_password',
+    new_password: 'new_password',
+    timezone: 'America/New_York'

+
+## Benefits Achieved
+
+### User Experience ✅
+- ✅ Consistent error messaging across all pages
+- ✅ Less intrusive than `alert()` dialogs (no blocking UI)
+- ✅ Auto-dismissing notifications (better UX)
+- ✅ Stackable notifications for multiple events
+- ✅ Better mobile experience (no modal blocking)
+- ✅ Theme-aware styling (automatic dark/light mode)
+

+- ✅ Consistent API for showing notifications
+- ✅ Type-safe with TypeScript
+- ✅ Removed anti-pattern (`alert()`)
+
+### Code Quality ✅
+- ✅ Removed all `alert()` calls
+- ✅ Removed inline error message rendering
+- ✅ Follows React best practices
+- ✅ Improved component reusability
+- ✅ Better separation of concerns
+
+---
+
+## Remaining Work (Optional)
+
+### authInterceptor.ts (Global Error Handling)
+The `authInterceptor.ts` file could be enhanced to show toasts for global errors (401, 500, etc.), but this requires a global toast service or event system. This was marked as optional and not implemented.
+
+---
+
+## Deployment Notes
+
+### Backend Deployment
+1. The new `PUT /settings` endpoint requires:
+   - No database migrations (uses existing `UpdateUser` query)
+   - New Go dependencies: `github.com/alexedwards/argon2id` (verify if already present)
+
+2. Restart the backend service to pick up the new endpoint
+
+### Frontend Deployment
+1. No additional dependencies beyond `clsx` and `tailwind-merge` (already installed)
+2. Build and deploy as normal
+3. All toast functionality works client-side
+
+---
+
+## API Regeneration Commands
+
+If you need to regenerate the API in the future:
+
+```bash
+# Backend (Go)
+cd /home/evanreichard/Development/git/AnthoLume
+go generate ./api/v1/generate.go
+
+# Frontend (TypeScript)
+cd /home/evanreichard/Development/git/AnthoLume/frontend
+npm run generate:api
+```
+
+---
+
+## Summary
+
+All identified locations have been successfully migrated to use toast notifications:
+
+- ✅ 5 pages migrated (AdminPage, AdminUsersPage, AdminImportPage, LoginPage, DocumentsPage)
+- ✅ 10+ API operations now use toast notifications
+- ✅ All `alert()` calls removed
+- ✅ All inline error state removed
+- ✅ Settings page TODOs implemented with new v1 API endpoint
+- ✅ Backend `PUT /settings` endpoint created and tested
+- ✅ Frontend uses new endpoint with proper error handling
+- ✅ Skeleton loaders added where appropriate
+- ✅ Theme-aware styling throughout
+
+The application now has a consistent, modern error notification system that provides better UX and follows React best practices.

+
+---
+
+## Quick Migration Template
+
+```typescript
+// 1. Import hook
+import { useToasts } from '../components';
+
+// 2. Destructure needed methods
+const { showInfo, showWarning, showError } = useToasts();
+
+// 3. Replace inline state (if present)
+// REMOVE: const [message, setMessage] = useState<string | null>(null);
+// REMOVE: const [errorMessage, setErrorMessage] = useState<string | null>(null);
+
+// 4. Replace inline error rendering (if present)
+// REMOVE: {errorMessage && <span className="text-red-400 text-xs">{errorMessage}</span>}
+// REMOVE: {message && <span className="text-green-400 text-xs">{message}</span>}
+
+// 5. Replace alert() calls
+// BEFORE: alert('Error message');
+// AFTER: showError('Error message');
+
+// 6. Replace inline error state
+// BEFORE: setError('Invalid credentials');
+// AFTER: showError('Invalid credentials');
+
+// 7. Update mutation callbacks
+onSuccess: () => {
+  showInfo('Operation completed successfully');
+  // ... other logic
+},
+onError: (error: any) => {
+  showError('Operation failed: ' + error.message);
+  // ... or just showError() if error is handled elsewhere
+}
+```
+

+
+## Common Patterns
+
+### Replace alert() with showError
+```typescript
+// BEFORE
+onError: (error) => {
+  alert('Operation failed: ' + error.message);
+}
+
+// AFTER
+onError: (error: any) => {
+  showError('Operation failed: ' + error.message);
+}
+```
+
+### Replace alert() with showWarning
+```typescript
+// BEFORE
+if (!file.name.endsWith('.epub')) {
+  alert('Please upload an EPUB file');
+  return;
+}
+
+// AFTER
+if (!file.name.endsWith('.epub')) {
+  showWarning('Please upload an EPUB file');
+  return;
+}
+```
+
+### Replace inline error state
+```typescript
+// BEFORE
+const [error, setError] = useState('');
+setError('Invalid credentials');
+<span className="absolute -bottom-5 text-red-400 text-xs">{error}</span>
+
+// AFTER
+showError('Invalid credentials');
+// Remove the span from JSX
+```
+
+### Replace inline success/error messages
+```typescript
+// BEFORE
+const [message, setMessage] = useState<string | null>(null);
+const [errorMessage, setErrorMessage] = useState<string | null>(null);
+setMessage('Success!');
+setErrorMessage('Error!');
+{errorMessage && <span className="text-red-400 text-xs">{errorMessage}</span>}
+{message && <span className="text-green-400 text-xs">{message}</span>}
+
+// AFTER
+showInfo('Success!');
+showError('Error!');
+// Remove both spans from JSX
+```
+
+---
+
+## Toast Duration Guidelines
+
+- **Success messages**: 3000-5000ms (auto-dismiss)
+- **Warning messages**: 5000-10000ms (auto-dismiss)
+- **Error messages**: 0 (no auto-dismiss, user must dismiss)
+- **Validation warnings**: 3000-5000ms (auto-dismiss)
+
+Example:
+```typescript
+showInfo('Document uploaded successfully!');  // Default 5000ms
+showWarning('Low disk space', 10000);           // 10 seconds
+showError('Failed to save data', 0);             // No auto-dismiss
+```

+# Toast and Skeleton Components - Integration Guide
+
+## Overview
+
+I've added toast notifications and skeleton loading components to the AnthoLume React app. These components respect the current theme and automatically adapt to dark/light mode.
+
+## What Was Added
+
+### 1. Toast Notification System
+
+**Files Created:**
+- `src/components/Toast.tsx` - Individual toast component
+- `src/components/ToastContext.tsx` - Toast context and provider
+- `src/components/index.ts` - Centralized exports
+
+**Features:**
+- Three toast types: info, warning, error
+- Auto-dismiss with configurable duration
+- Manual dismiss via X button
+- Smooth animations (slide in/out)
+- Theme-aware colors for both light and dark modes
+- Fixed positioning (top-right corner)
+
+**Usage:**
+```tsx
+import { useToasts } from './components/ToastContext';
+
+function MyComponent() {
+  const { showInfo, showWarning, showError, showToast } = useToasts();
+
+  const handleAction = async () => {
+    try {
+      await someApiCall();
+      showInfo('Operation completed successfully!');
+    } catch (error) {
+      showError('An error occurred: ' + error.message);
+    }
+  };
+
+  return <button onClick={handleAction}>Click me</button>;
+}
+```
+
+### 2. Skeleton Loading Components
+
+**Files Created:**
+- `src/components/Skeleton.tsx` - All skeleton components
+- `src/utils/cn.ts` - Utility for className merging
+- `src/pages/ComponentDemoPage.tsx` - Demo page showing all components
+
+**Components Available:**
+- `Skeleton` - Basic skeleton element (default, text, circular, rectangular variants)
+- `SkeletonText` - Multiple lines of text skeleton
+- `SkeletonAvatar` - Avatar placeholder (sm, md, lg, or custom size)
+- `SkeletonCard` - Card placeholder with optional avatar/title/text
+- `SkeletonTable` - Table skeleton with configurable rows/columns
+- `SkeletonButton` - Button placeholder
+- `PageLoader` - Full-page loading spinner with message
+- `InlineLoader` - Small inline spinner (sm, md, lg sizes)
+
+**Usage Examples:**
+
+```tsx
+import { 
+  Skeleton, 
+  SkeletonText, 
+  SkeletonCard, 
+  SkeletonTable,
+  PageLoader 
+} from './components';
+
+// Basic skeleton
+<Skeleton className="w-full h-8" />
+
+// Text skeleton
+<SkeletonText lines={3} />
+
+// Card skeleton
+<SkeletonCard showAvatar showTitle showText textLines={4} />
+
+// Table skeleton (already integrated into Table component)
+<Table columns={columns} data={data} loading={isLoading} />
+
+// Page loader
+<PageLoader message="Loading your documents..." />
+```
+
+### 3. Updated Components
+
+**Table Component** (`src/components/Table.tsx`):
+- Now displays skeleton table when `loading={true}`
+- Automatically shows 5 rows with skeleton content
+- Matches the column count of the actual table
+
+**Main App** (`src/main.tsx`):
+- Wrapped with `ToastProvider` to enable toast functionality throughout the app
+
+**Global Styles** (`src/index.css`):
+- Added `animate-wave` animation for skeleton components
+- Theme-aware wave animation for both light and dark modes
+
+## Dependencies Added
+
+```bash
+npm install clsx tailwind-merge
+```
+
+## Integration Examples
+
+### Example 1: Updating SettingsPage with Toasts
+
+```tsx
+import { useToasts } from '../components/ToastContext';
+import { useUpdatePassword } from '../generated/anthoLumeAPIV1';
+
+export default function SettingsPage() {
+  const { showInfo, showError } = useToasts();
+  const updatePassword = useUpdatePassword();
+
+  const handlePasswordSubmit = async (e: FormEvent) => {
+    e.preventDefault();
+    try {
+      await updatePassword.mutateAsync({
+        data: { password, newPassword }
+      });
+      showInfo('Password updated successfully!');
+      setPassword('');
+      setNewPassword('');
+    } catch (error) {
+      showError('Failed to update password. Please try again.');
+    }
+  };
+  // ... rest of component
+}
+```
+
+### Example 2: Using PageLoader for Initial Load
+
+```tsx
+import { PageLoader } from '../components';
+
+export default function DocumentsPage() {
+  const { data, isLoading } = useGetDocuments();
+
+  if (isLoading) {
+    return <PageLoader message="Loading your documents..." />;
+  }
+
+  // ... render documents
+}
+```
+
+### Example 3: Custom Skeleton for Complex Loading
+
+```tsx
+import { SkeletonCard } from '../components';
+
+function UserProfile() {
+  const { data, isLoading } = useGetProfile();
+
+  if (isLoading) {
+    return (
+      <div className="grid grid-cols-1 md:grid-cols-2 gap-4">
+        <SkeletonCard showAvatar showTitle showText textLines={4} />
+        <SkeletonCard showAvatar showTitle showText textLines={4} />
+      </div>
+    );
+  }
+
+  // ... render profile data
+}
+```
+
+## Theme Support
+
+All components automatically adapt to the current theme:
+
+**Light Mode:**
+- Toasts: Light backgrounds with appropriate colored borders/text
+- Skeletons: `bg-gray-200` (light gray)
+
+**Dark Mode:**
+- Toasts: Dark backgrounds with adjusted colored borders/text
+- Skeletons: `bg-gray-600` (dark gray)
+
+The theme is controlled via Tailwind's `dark:` classes, which respond to:
+- System preference (via `darkMode: 'media'` in tailwind.config.js)
+- Future manual theme toggles (can be added to `darkMode: 'class'`)
+
+## Demo Page
+
+A comprehensive demo page is available at `src/pages/ComponentDemoPage.tsx` that showcases:
+- All toast notification types
+- All skeleton component variants
+- Interactive examples
+
+To view the demo:
+1. Add a route for the demo page in `src/Routes.tsx`:
+```tsx
+import ComponentDemoPage from './pages/ComponentDemoPage';
+
+// Add to your routes:
+<Route path="/demo" element={<ComponentDemoPage />} />
+```
+
+2. Navigate to `/demo` to see all components in action
+
+## Best Practices
+
+### Toasts:
+- Use `showInfo()` for success messages and general notifications
+- Use `showWarning()` for non-critical issues that need attention
+- Use `showError()` for critical failures
+- Set duration to `0` for errors that require user acknowledgment
+- Keep messages concise and actionable
+
+### Skeletons:
+- Use `PageLoader` for full-page loading states
+- Use `SkeletonTable` for table data (already integrated)
+- Use `SkeletonCard` for card-based layouts
+- Match skeleton structure to actual content structure
+- Use appropriate variants (text, circular, etc.) for different content types
+
+## Files Changed/Created Summary
+
+**Created:**
+- `src/components/Toast.tsx`
+- `src/components/ToastContext.tsx`
+- `src/components/Skeleton.tsx`
+- `src/components/index.ts`
+- `src/utils/cn.ts`
+- `src/pages/ComponentDemoPage.tsx`
+- `src/components/README.md`
+
+**Modified:**
+- `src/main.tsx` - Added ToastProvider wrapper
+- `src/index.css` - Added wave animation for skeletons
+- `src/components/Table.tsx` - Integrated skeleton loading
+- `package.json` - Added clsx and tailwind-merge dependencies
+
+## Next Steps
+
+1. **Replace legacy error pages**: Start using toast notifications instead of the Go template error pages
+2. **Update API error handling**: Add toast notifications to API error handlers in auth interceptor
+3. **Enhance loading states**: Replace simple "Loading..." text with appropriate skeleton components
+4. **Add theme toggle**: Consider adding a manual dark/light mode toggle (currently uses system preference)
+5. **Add toasts to mutations**: Integrate toast notifications into all form submissions and API mutations

+# UI Components
+
+This directory contains reusable UI components for the AnthoLume application.
+
+## Toast Notifications
+
+### Usage
+
+The toast system provides info, warning, and error notifications that respect the current theme and dark/light mode.
+
+```tsx
+import { useToasts } from './components/ToastContext';
+
+function MyComponent() {
+  const { showInfo, showWarning, showError, showToast } = useToasts();
+
+  const handleAction = async () => {
+    try {
+      // Do something
+      showInfo('Operation completed successfully!');
+    } catch (error) {
+      showError('An error occurred while processing your request.');
+    }
+  };
+
+  return <button onClick={handleAction}>Click me</button>;
+}
+```
+
+### API
+
+- `showToast(message: string, type?: 'info' | 'warning' | 'error', duration?: number): string`
+  - Shows a toast notification
+  - Returns the toast ID for manual removal
+  - Default type: 'info'
+  - Default duration: 5000ms (0 = no auto-dismiss)
+
+- `showInfo(message: string, duration?: number): string`
+  - Shortcut for showing an info toast
+
+- `showWarning(message: string, duration?: number): string`
+  - Shortcut for showing a warning toast
+
+- `showError(message: string, duration?: number): string`
+  - Shortcut for showing an error toast
+
+- `removeToast(id: string): void`
+  - Manually remove a toast by ID
+
+- `clearToasts(): void`
+  - Clear all active toasts
+
+### Examples
+
+```tsx
+// Info toast (auto-dismisses after 5 seconds)
+showInfo('Document saved successfully!');
+
+// Warning toast (auto-dismisses after 10 seconds)
+showWarning('Low disk space warning', 10000);
+
+// Error toast (no auto-dismiss)
+showError('Failed to load data', 0);
+
+// Generic toast
+showToast('Custom message', 'warning', 3000);
+```
+
+## Skeleton Loading
+
+### Usage
+
+Skeleton components provide placeholder content while data is loading. They automatically adapt to dark/light mode.
+
+### Components
+
+#### `Skeleton`
+
+Basic skeleton element with various variants:
+
+```tsx
+import { Skeleton } from './components/Skeleton';
+
+// Default (rounded rectangle)
+<Skeleton className="w-full h-8" />
+
+// Text variant
+<Skeleton variant="text" className="w-3/4" />
+
+// Circular variant (for avatars)
+<Skeleton variant="circular" width={40} height={40} />
+
+// Rectangular variant
+<Skeleton variant="rectangular" width="100%" height={200} />
+```
+
+#### `SkeletonText`
+
+Multiple lines of text skeleton:
+
+```tsx
+<SkeletonText lines={3} />
+<SkeletonText lines={5} className="max-w-md" />
+```
+
+#### `SkeletonAvatar`
+
+Avatar placeholder:
+
+```tsx
+<SkeletonAvatar size="md" />
+<SkeletonAvatar size={56} />
+```
+
+#### `SkeletonCard`
+
+Card placeholder with optional elements:
+
+```tsx
+// Default card
+<SkeletonCard />
+
+// With avatar
+<SkeletonCard showAvatar />
+
+// Custom configuration
+<SkeletonCard 
+  showAvatar 
+  showTitle 
+  showText 
+  textLines={4}
+  className="max-w-sm"
+/>
+```
+
+#### `SkeletonTable`
+
+Table placeholder:
+
+```tsx
+<SkeletonTable rows={5} columns={4} />
+<SkeletonTable rows={10} columns={6} showHeader={false} />
+```
+
+#### `SkeletonButton`
+
+Button placeholder:
+
+```tsx
+<SkeletonButton width={120} />
+<SkeletonButton className="w-full" />
+```
+
+#### `PageLoader`
+
+Full-page loading indicator:
+
+```tsx
+<PageLoader message="Loading your documents..." />
+```
+
+#### `InlineLoader`
+
+Small inline loading spinner:
+
+```tsx
+<InlineLoader size="sm" />
+<InlineLoader size="md" />
+<InlineLoader size="lg" />
+```
+
+## Integration with Table Component
+
+The Table component now supports skeleton loading:
+
+```tsx
+import { Table, SkeletonTable } from './components/Table';
+
+function DocumentList() {
+  const { data, isLoading } = useGetDocuments();
+
+  if (isLoading) {
+    return <SkeletonTable rows={10} columns={5} />;
+  }
+
+  return (
+    <Table
+      columns={columns}
+      data={data?.documents || []}
+    />
+  );
+}
+```
+
+## Theme Support
+
+All components automatically adapt to the current theme:
+
+- **Light mode**: Uses gray tones for skeletons, appropriate colors for toasts
+- **Dark mode**: Uses darker gray tones for skeletons, adjusted colors for toasts
+
+The theme is controlled via Tailwind's `dark:` classes, which respond to the system preference or manual theme toggles.
+
+## Dependencies
+
+- `clsx` - Utility for constructing className strings
+- `tailwind-merge` - Merges Tailwind CSS classes intelligently
+- `lucide-react` - Icon library used by Toast component
