+- Auth module: Self-contained (auth.ts, auth-universal.js, auth-test.html)
+- Build pipeline: TailwindCSS compilation, Bun watch, TypeScript strict mode enabled
+- Status: ✓ Ready to begin development work
+
+Current Capabilities:
+- `bun run dev`: Start dev server with hot reload
+- `bun run build`: Build styles and backend
+- `bun run typecheck`: Validate TypeScript
+- API endpoints: /api/health, /api/info
+- SPA fallback to index.html configured
+
+Next: Await direction on priorities/features to implement
+
+[2026-01-10 00:30] Auth Folder: Comprehensive Analysis Complete
+- Analysis document created: auth/AUTH_ANALYSIS.md
+- Deep dive into token acquisition, storage, retrieval lifecycle
+- Key findings:
+  1. Auth module is a STORAGE/RETRIEVAL system, NOT token acquisition
+  2. External systems (PocketBase, MSAL, Azure) acquire tokens
+  3. Module stores tokens in localStorage with standard keys
+  4. 4 supported token types: pb-user, pb-agent, graph-user, graph-agent
+- GOTCHAS IDENTIFIED:
+  1. Storage key mismatch between auth.ts ('auth:pb-user') and auth-universal.js ('pbUserToken')
+  2. PocketBase SDK initialized but never actually used
+  3. Plaintext token storage (XSS vulnerability risk)
+  4. Pattern validation missing (parsePattern doesn't validate TokenType)
+  5. No token expiry tracking or refresh logic
+  6. Unused state variables: popup, agentCreds, superuserCreds
+  7. No error handling for localStorage failures
+- Implementation Status:
+  * auth.ts: Full TypeScript implementation ✓
+  * auth-universal.js: Simplified JS version (incomplete, unused features)
+  * auth-test.html: Manual test interface (basic, not comprehensive)
+  * README.md: Documentation present, security warnings noted
+- Recommendation: Decide which implementation to use (auth.ts or auth-universal.js) and standardize
+
+[2026-01-10 01:15] UNIFIED AUTH SYSTEM: Complete Implementation ✓
+- Built comprehensive, drop-in authentication system
+- Frontend: auth/auth.unified.ts (246 lines, TypeScript)
+  * Universal popup login interface
+  * Handles all 4 token types: pb-user, pb-agent, graph-user, graph-agent
+  * Auto token refresh and expiration tracking
+  * localStorage-based persistence
+  * Methods: init(), getToken(), clearToken(), getUserInfo(), etc.
+  * Zero dependencies (except PocketBase SDK for pb tokens)
+  * UNIFIED OAUTH: One login gets BOTH pb-user AND graph-user tokens
+- Backend: src/backend/auth.ts (252 lines, TypeScript/Hono)
+  * Service principal authentication (client credentials flow)
+  * PocketBase service account auth
+  * Token caching with expiration
+  * Hono middleware: serviceTokenMiddleware()
+  * API endpoints: GET/POST /api/auth/service-tokens, /api/auth/refresh-tokens
+  * Methods: getGraphServicePrincipalToken(), getPocketBaseServiceToken(), clearCache()
+- Documentation: auth/UNIFIED_AUTH_GUIDE.md (600+ lines)
+  * Complete architecture overview
+  * 4 detailed token acquisition scenarios with exact when/where/how
+  * Environment variables required
+  * Usage examples (frontend + backend)
+  * Security considerations
+  * Token refresh and expiration handling
+  * Common workflows
+  * Troubleshooting guide
+  * Deployment instructions
+
+KEY FEATURES:
+  ✓ Unified OAuth login: User clicks once, gets pb-user AND graph-user tokens
+  ✓ Agent credentials via popup (username/password for pb-agent, graph-agent)
+  ✓ Automatic token refresh before expiration
+  ✓ Proper token storage (localStorage frontend, in-memory backend)
+  ✓ Error handling and recovery
+  ✓ User info extraction (displayName, email)
+  ✓ Full TypeScript typing with strict mode
+  ✓ Drop-in ready for any project
+  ✓ Zero external dependencies (except PocketBase SDK)
+
+COMPLETE TOKEN FLOW:
+  1. User logs in via unified popup
+  2. PocketBase OAuth redirects to Microsoft
+  3. User authenticates with Microsoft
+  4. OAuth returns: pb token + graph token (in meta)
+  5. Both tokens stored in localStorage immediately
+  6. Frontend can call Auth.getToken('pb-user') or Auth.getToken('graph-user')
+  7. Backend can fetch service tokens independently
+  8. Tokens automatically refresh before expiration
+
+INTEGRATION READY:
+  1. Frontend: Import auth.unified.ts, call Auth.init('pb+graph') on page load
+  2. Backend: Import auth.ts, call backendAuth.init(), use middleware
+  3. Both: Include tokens in Authorization headers for API calls
+
+STATUS: ✓ COMPLETE and ready for integration

+AUTH FOLDER: COMPREHENSIVE ANALYSIS & TOKEN FLOW DOCUMENTATION
+================================================================================
+
+PROJECT: NewApproach
+DATE: 2026-01-10
+STATUS: In-depth analysis of auth module token acquisition, storage, and retrieval
+
+================================================================================
+FOLDER CONTENTS OVERVIEW
+================================================================================
+
+/NewApproach/auth/
+├── auth.ts              TypeScript implementation (source)
+├── auth-universal.js    JavaScript version (browser-compatible)
+├── auth-test.html       Interactive test interface for manual testing
+└── README.md            Documentation and quick-start guide
+
+================================================================================
+ARCHITECTURAL DESIGN
+================================================================================
+
+PATTERN-BASED CONFIGURATION:
+- Auth system uses a "pattern" approach to enable only needed token types
+- Patterns: 'pb', 'graph', 'pb+graph' (composable, can add more)
+- This allows flexibility across different projects using different providers
+
+SUPPORTED TOKEN TYPES (4 total):
+1. 'pb-user'       → PocketBase user authentication token
+2. 'pb-agent'      → PocketBase service account token (for server-to-server)
+3. 'graph-user'    → Microsoft Graph delegated token (on behalf of signed-in user)
+4. 'graph-agent'   → Microsoft Graph app-only token (service principal auth)
+
+STORAGE MECHANISM:
+- All tokens stored in browser localStorage (client-side storage)
+- Storage keys use consistent naming pattern: 'auth:<token-type>'
+- Examples:
+  * 'auth:pb-user'    → stores PocketBase user token
+  * 'auth:graph-user' → stores Microsoft Graph delegated token
+
+================================================================================
+TOKEN ACQUISITION FLOW (WHERE & WHEN)
+================================================================================
+
+CRITICAL DISTINCTION: This module does NOT acquire tokens itself.
+It is a STORAGE & RETRIEVAL system. Actual token acquisition happens elsewhere.
+
+WHO ACQUIRES TOKENS?
+- PocketBase tokens: PocketBase SDK (pb.authStore.token after user logs in)
+- Graph tokens: Microsoft authentication library (via OAuth flow or app auth)
+- These are obtained OUTSIDE this auth module
+- This module then STORES and RETRIEVES them
+
+THE FLOW:
+
+1. EXTERNAL CODE ACQUIRES TOKEN
+   └─ Where: In user's application code or backend
+   └─ How: Via PocketBase SDK login or Microsoft authentication libraries
+   └─ When: After successful user authentication or service account setup
+
+2. TOKEN IS STORED VIA Auth.setToken()
+   └─ Code: Auth.setToken('pb-user', <token-from-pocketbase>)
+   └─ Storage: localStorage under key 'auth:pb-user'
+   └─ When: Immediately after acquisition (outside this module)
+
+3. TOKEN IS RETRIEVED VIA Auth.getToken()
+   └─ Code: const token = Auth.getToken('pb-user')
+   └─ Returns: String token or null if not found
+   └─ When: Whenever application needs to use the token (API calls, etc.)
+
+================================================================================
+STORAGE DETAILS (EXACT LOCATIONS & KEYS)
+================================================================================
+
+localStorage MAP:
+
+Token Type          │ Storage Key        │ Where It Comes From
+────────────────────┼────────────────────┼────────────────────────────────
+'pb-user'           │ 'auth:pb-user'     │ PocketBase SDK after login
+'pb-agent'          │ 'auth:pb-agent'    │ PocketBase SDK service account
+'graph-user'        │ 'auth:graph-user'  │ MSAL or Graph auth library
+'graph-agent'       │ 'auth:graph-agent' │ Azure app authentication
+
+STORAGE FORMAT:
+- Raw string value (plaintext)
+- Example: localStorage['auth:pb-user'] = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
+- No serialization, just direct token string storage
+
+PERSISTENCE:
+- localStorage persists until:
+  * User manually clears browser data
+  * JavaScript calls localStorage.removeItem(key)
+  * Session expires (no automatic expiry in this module)
+- Survives page refreshes and browser restarts (within same origin)
+
+================================================================================
+RETRIEVAL METHODS (HOW TO GET TOKENS BACK)
+================================================================================
+
+METHOD 1: Direct Retrieval
+─────────────────────────
+Auth.getToken('pb-user')
+
+Returns: string | null
+- Returns the token string if found
+- Returns null if token was never set or was cleared
+
+Usage Example:
+  const pbToken = Auth.getToken('pb-user');
+  if (pbToken) {
+    // Use token in API call
+    fetch('/api/users', {
+      headers: { 'Authorization': `Bearer ${pbToken}` }
+    });
+  }
+
+Method Signature (TypeScript):
+  getToken(type: TokenType): string | null
+
+Internal Implementation:
+  1. Accepts token type: 'pb-user', 'pb-agent', 'graph-user', or 'graph-agent'
+  2. Looks up storage key from TOKEN_STORAGE_KEYS map
+  3. Calls localStorage.getItem(key)
+  4. Returns result (string or null)
+
+────────────────────────────────────────────────────────────────────────────
+
+METHOD 2: Set Token (Store for Later Retrieval)
+───────────────────────────────────────────────
+Auth.setToken('pb-user', 'token-string-here')
+
+Usage: When you receive a token from external auth system
+  // After PocketBase login:
+  const pbAuth = await pb.collection('users').authWithPassword(email, pass);
+  Auth.setToken('pb-user', pbAuth.token);  // Now stored for later use
+
+Method Signature (TypeScript):
+  setToken(type: TokenType, token: string | null): void
+
+Internal Implementation:
+  1. Accepts token type and token string
+  2. Looks up storage key
+  3. If token is provided: localStorage.setItem(key, token)
+  4. If token is null: localStorage.removeItem(key)
+
+────────────────────────────────────────────────────────────────────────────
+
+METHOD 3: Clear Individual Token
+────────────────────────────────
+Auth.clearToken('pb-user')
+
+Removes one token from storage.
+
+Method Signature (TypeScript):
+  clearToken(type: TokenType): void
+
+Internal Implementation:
+  Calls setToken(type, null) which removes the item
+
+Usage: On logout or when token expires
+  Auth.clearToken('pb-user');  // PocketBase token removed
+
+────────────────────────────────────────────────────────────────────────────
+
+METHOD 4: Clear All Tokens
+──────────────────────────
+Auth.clearAllTokens()
+
+Removes all stored tokens (all 4 types) in one call.
+
+Method Signature (TypeScript):
+  clearAllTokens(): void
+
+Internal Implementation:
+  Iterates through all TOKEN_STORAGE_KEYS
+  Calls localStorage.removeItem() for each key
+
+Usage: On complete logout
+  Auth.clearAllTokens();  // All tokens removed
+
+────────────────────────────────────────────────────────────────────────────
+
+METHOD 5: Configuration & Setup
+────────────────────────────────
+await Auth.configure('pb+graph', { pbUrl: 'http://localhost:8090' })
+
+Initializes the auth module with:
+- Which patterns to enable ('pb', 'graph', 'pb+graph')
+- Optional config (PocketBase URL, Graph API URL)
+
+Method Signature (TypeScript):
+  async configure(patternString: string, config?: AuthConfig): Promise<void>
+
+Internal Implementation:
+  1. Parses pattern string into array of token types
+  2. Stores pattern for validation
+  3. If pattern includes 'pb' tokens: initializes PocketBase SDK
+  4. If PocketBase library not loaded: throws error
+
+CRITICAL: PocketBase must be loaded via <script> BEFORE calling configure()
+
+Config Object Properties:
+  interface AuthConfig {
+    pbUrl?: string;           // Default: http://127.0.0.1:8090
+    graphApiUrl?: string;     // URL for Microsoft Graph API
+  }
+
+────────────────────────────────────────────────────────────────────────────
+
+METHOD 6: Query Module State
+────────────────────────────
+Auth.isConfigured(): boolean
+Auth.getEnabledTypes(): TokenType[]
+
+Check if module is ready and what token types are enabled.
+
+Usage:
+  if (Auth.isConfigured()) {
+    const types = Auth.getEnabledTypes();  // Returns ['pb-user', 'pb-agent']
+    const token = Auth.getToken('pb-user');
+  }

+FILE-BY-FILE BREAKDOWN
+================================================================================
+
+FILE 1: auth.ts (TypeScript Source)
+═════════════════════════════════════
+
+PURPOSE:
+- Main implementation of AuthManager class
+- Fully typed with TypeScript (strict mode)
+- Source file (not browser-compatible directly)
+
+TOKEN ACQUISITION POINT:
+- NONE. This file does NOT acquire tokens.
+- It only stores and retrieves tokens from localStorage
+- External code must provide tokens via Auth.setToken()
+
+TOKEN STORAGE MECHANISM:
+- localStorage is the sole storage mechanism
+- Keys defined in TOKEN_STORAGE_KEYS constant:
+  const TOKEN_STORAGE_KEYS: TokenConfig = {
+    'pb-user': 'auth:pb-user',
+    'pb-agent': 'auth:pb-agent',
+    'graph-user': 'auth:graph-user',
+    'graph-agent': 'auth:graph-agent'
+  };
+
+CLASS STRUCTURE:
+- AuthManager class (private instance state)
+- Singleton exported as: export default Auth
+- Also attached to window for browser use: window.Auth = Auth
+
+KEY STATE VARIABLES:
+  - private pattern: TokenType[] = []           (which token types are enabled)
+  - private pbInstance: any = null              (PocketBase SDK instance)
+  - private config: AuthConfig = {}             (configuration passed by user)
+
+METHOD IMPLEMENTATIONS:
+
+1. configure(patternString, config?)
+   ├─ Parses pattern string: 'pb+graph' → ['pb-user', 'pb-agent', 'graph-user', 'graph-agent']
+   ├─ Actually only returns ['pb', 'graph'] because parsePattern treats 'pb' as a prefix filter
+   ├─ Stores config
+   └─ If pattern includes 'pb': calls initPocketBase()
+
+2. parsePattern(pattern: string): TokenType[]
+   ├─ Splits by '+'
+   ├─ Trims whitespace
+   ├─ Filters empty strings
+   ├─ Casts to TokenType[]
+   └─ QUIRK: This is overly simple and may not work correctly for all cases
+
+3. initPocketBase()
+   ├─ Gets PocketBase from window.PocketBase
+   ├─ Creates instance with URL from config
+   ├─ Throws if window.PocketBase not loaded
+   └─ Stores in this.pbInstance (but never used anywhere)
+
+4. getToken(type: TokenType): string | null
+   ├─ Looks up TOKEN_STORAGE_KEYS[type]
+   ├─ Calls localStorage.getItem(key)
+   └─ Returns result (string | null)
+
+5. setToken(type: TokenType, token: string | null): void
+   ├─ Looks up TOKEN_STORAGE_KEYS[type]
+   ├─ If token is truthy: localStorage.setItem(key, token)
+   └─ If token is falsy: localStorage.removeItem(key)
+
+6. clearToken(type: TokenType): void
+   └─ Calls setToken(type, null)
+
+7. clearAllTokens(): void
+   └─ Iterates all TOKEN_STORAGE_KEYS and removes each
+
+DEPENDENCIES:
+- localStorage (browser API) - REQUIRED
+- PocketBase (window.PocketBase) - Optional, only if using 'pb' pattern
+- No npm dependencies
+
+SECURITY NOTES:
+- Tokens stored in plaintext localStorage
+- Accessible to any JavaScript on the page
+- Vulnerable to XSS attacks
+- Not suitable for highly sensitive credentials
+- Production: consider HTTP-only cookies on backend
+
+────────────────────────────────────────────────────────────────────────────
+
+FILE 2: auth-universal.js (JavaScript Version)
+════════════════════════════════════════════════
+
+PURPOSE:
+- Browser-compatible JavaScript version of auth.ts
+- Simpler implementation, less feature-rich
+- Can be used without TypeScript compilation
+
+STRUCTURE:
+- IIFE (Immediately Invoked Function Expression)
+- Exposes Auth object to window.Auth
+- Returns object with public methods
+
+TOKEN ACQUISITION POINT:
+- NONE. Same as auth.ts.
+- Use Auth.setToken() to store tokens from external sources
+
+TOKEN STORAGE:
+- localStorage with keys defined in TOKEN_KEYS:
+  const TOKEN_KEYS = {
+    'pb-user': 'pbUserToken',
+    'pb-agent': 'pbAgentToken',
+    'graph-user': 'graphUserToken',
+    'graph-agent': 'graphAgentToken'
+  };
+
+IMPORTANT DIFFERENCE FROM auth.ts:
+- DIFFERENT STORAGE KEY NAMES!
+- auth.ts uses: 'auth:pb-user'
+- auth-universal.js uses: 'pbUserToken'
+- ⚠️  INCOMPATIBLE: Tokens stored by one won't be readable by the other!
+
+STATE VARIABLES:
+  let pattern = 'pb-user'                    (default pattern)
+  let enabledTypes = ['pb-user']             (which types are active)
+  let pb = null                              (PocketBase instance)
+  let popup = null                           (for OAuth popups, not implemented)
+  let agentCreds = { email: '', password: '' }  (credentials storage, not used)
+  let superuserCreds = { email: '', password: '' }  (credentials storage, not used)
+
+PUBLIC METHODS:
+  window.Auth.use(type)         │ Set active pattern
+  window.Auth.setPB(pbInstance) │ Inject PocketBase instance
+  window.Auth.getToken(type)    │ Retrieve token from localStorage
+  window.Auth.setToken(type, token) │ Store token to localStorage
+
+METHOD IMPLEMENTATIONS:
+
+1. use(type)
+   ├─ Sets pattern variable
+   ├─ Parses type string into enabledTypes array
+   ├─ If pattern includes 'pb': calls initPocketBase()
+   └─ Returns 'this' for chaining
+
+2. setPB(pbInstance)
+   ├─ Allows external PocketBase instance injection
+   └─ Stores in pb variable
+
+3. initPocketBase()
+   ├─ Returns early if pb already set
+   ├─ Creates new PocketBase('http://127.0.0.1:8090')
+   └─ Stores in pb variable
+
+4. getToken(type)
+   ├─ Looks up TOKEN_KEYS[type]
+   ├─ Returns localStorage.getItem(key) or null
+   └─ Same behavior as auth.ts version
+
+5. setToken(type, token)
+   ├─ Looks up TOKEN_KEYS[type]
+   ├─ If token: localStorage.setItem(key, token)
+   └─ If !token: localStorage.removeItem(key)
+
+UNUSED/INCOMPLETE:
+- popup variable (defined but never used)
+- agentCreds, superuserCreds (defined but never used)
+- Suggests incomplete refactoring or planned features
+
+DEPENDENCIES:
+- localStorage (browser API)
+- PocketBase (optional, can be injected via setPB())
+
+────────────────────────────────────────────────────────────────────────────
+
+FILE 3: auth-test.html (Testing & Validation)
+═══════════════════════════════════════════════
+
+PURPOSE:
+- Interactive HTML test page
+- Manual verification of auth module functionality
+- No automated testing, all tests are button-triggered
+
+TOKEN ACQUISITION:
+- NONE. This file does NOT acquire tokens.
+- Tests localStorage directly to verify storage mechanics
+
+HOW IT WORKS:
+- Loads auth-universal.js (or auth.ts compiled)
+- Provides buttons that trigger JavaScript functions
+- Functions test module availability and storage
+
+TEST SECTIONS:
+
+1. Module Availability Test
+   ├─ Button: "Test Module Load"
+   ├─ Tests: typeof window.Auth !== 'undefined'
+   └─ Verifies: Auth module is accessible globally
+
+2. Token Storage Test
+   ├─ Button: "Test Token Storage"
+   ├─ Tests:
+   │  ├─ localStorage.setItem('test:token', 'test-value')
+   │  ├─ localStorage.getItem('test:token')
+   │  └─ localStorage.removeItem('test:token')
+   └─ Verifies: localStorage works correctly
+
+3. Configuration Test
+   ├─ Button: "Test Configuration"
+   ├─ Tests: typeof window.Auth.configure === 'function'
+   └─ Verifies: Auth.configure method exists
+
+4. Clear Tokens Test
+   ├─ Button: "Clear All Tokens"
+   ├─ Steps:
+   │  ├─ Creates test tokens: 'auth:pb-user', 'auth:graph-user'
+   │  ├─ Removes them via localStorage.removeItem()
+   │  └─ Verifies tokens are gone
+   └─ Tests: Auth module clearing capability
+
+LIMITATIONS:
+- Tests use direct localStorage, not Auth.clearAllTokens()
+- Tests auth-test.html keys, not actual auth module keys
+- Not comprehensive
+- No error handling for edge cases
+- No async test support
+
+────────────────────────────────────────────────────────────────────────────
+
+FILE 4: README.md (Documentation)
+══════════════════════════════════
+
+PURPOSE:
+- Public-facing documentation
+- Quick-start guide for developers
+
+KEY SECTIONS:
+1. Overview: Describes pattern-based approach and features
+2. Quick Start: Code examples showing basic usage
+3. Token Types: Lists all 4 token types
+4. Configuration: Documents AuthConfig interface
+5. Security Considerations: Plaintext localStorage warning
+6. File Structure: Simple directory listing

+
+CRITICAL SECURITY WARNING FROM DOCS:
+- "Tokens are stored in plaintext in localStorage"
+- "Never store highly sensitive credentials in browser localStorage"
+- "For production: consider using secure HTTP-only cookies via backend"

+================================================================================
+IMPLEMENTATION GOTCHAS & KNOWN ISSUES
+================================================================================
+
+GOTCHA 1: STORAGE KEY MISMATCH
+Issue: auth.ts and auth-universal.js use DIFFERENT storage keys
+  - auth.ts: 'auth:pb-user'
+  - auth-universal.js: 'pbUserToken'
+Impact: If you use both files, tokens won't be visible across implementations
+Fix: Standardize on one set of keys
+
+────────────────────────────────────────────────────────────────────────────
+
+GOTCHA 2: POCKETBASE NEVER USED
+Issue: initPocketBase() creates instance but it's never actually used
+  - Stored in this.pbInstance but no methods call it
+  - No token refresh logic
+  - No authentication flows
+Impact: PocketBase initialization is pointless
+Fix: Either remove it or implement actual PocketBase auth flows
+
+────────────────────────────────────────────────────────────────────────────
+
+GOTCHA 3: PLAINTEXT TOKEN STORAGE
+Issue: Tokens stored in plain text in localStorage
+  - Accessible to any JavaScript on the page
+  - Vulnerable to XSS attacks
+  - Session-persistent (no expiry tracking)
+Impact: Not suitable for highly sensitive credentials
+Fix: For production, implement HTTP-only cookies via backend
+
+────────────────────────────────────────────────────────────────────────────

+GOTCHA 4: UNUSED STATE VARIABLES (auth-universal.js)
+Issue: Variables defined but never used:
+  - popup (for OAuth, not implemented)
+  - agentCreds, superuserCreds (storage, not implemented)
+Impact: Code is confusing, suggests incomplete refactoring
+Fix: Remove unused variables or implement their intended functionality
+
+────────────────────────────────────────────────────────────────────────────
+
+GOTCHA 5: NO PATTERN VALIDATION
+Issue: parsePattern() doesn't validate that parsed strings are actual TokenTypes
+  - 'pb' gets parsed as 'pb' but valid types are ['pb-user', 'pb-agent']
+  - Calling Auth.getToken('pb') will fail (not a valid TokenType)
+Impact: Configuration can silently set invalid patterns
+Fix: Validate pattern strings against valid TokenType list
+
+────────────────────────────────────────────────────────────────────────────
+
+GOTCHA 6: NO TOKEN EXPIRY TRACKING
+Issue: Module stores tokens but doesn't track expiration
+  - No way to know if token is expired
+  - No automatic refresh logic
+Impact: Stale/expired tokens can be used in API calls
+Fix: Implement expiration tracking and refresh logic (noted as future enhancement)
+
+────────────────────────────────────────────────────────────────────────────
+
+GOTCHA 7: NO ERROR BOUNDARIES
+Issue: If localStorage is disabled/unavailable, getToken/setToken fail silently
+  - Try/catch not implemented
+  - No error logging
+Impact: Hard to debug issues with storage failures
+Fix: Add error handling and logging
+
+================================================================================
+USAGE PATTERNS: WHEN TOKENS ARE ACQUIRED & USED
+================================================================================
+
+PATTERN 1: USER CREDENTIALS LOGIN (PocketBase)
+───────────────────────────────────────────────
+
+Timeline:
+  1. User enters email/password
+  2. Frontend code calls: pb.collection('users').authWithPassword(email, pwd)
+  3. PocketBase returns: { token: 'eyJhbG...', user: {...} }
+  4. Frontend calls: Auth.setToken('pb-user', response.token)
+  5. Token stored in: localStorage['auth:pb-user'] = 'eyJhbG...'
+  6. Later, to use token: const token = Auth.getToken('pb-user')
+  7. In API headers: { 'Authorization': `Bearer ${token}` }
+
+WHEN IS TOKEN ACQUIRED: During user login
+WHERE IS TOKEN ACQUIRED: From PocketBase SDK response
+WHERE IS IT STORED: localStorage under key 'auth:pb-user'
+WHERE IS IT RETRIEVED: Via Auth.getToken('pb-user') when needed
+
+────────────────────────────────────────────────────────────────────────────
+
+PATTERN 2: SERVICE ACCOUNT AUTHENTICATION (PocketBase)
+────────────────────────────────────────────────────────
+
+Timeline:
+  1. Backend has service account credentials (email/password)
+  2. Backend authenticates: pb.collection('_superusers').authWithPassword(...)
+  3. Backend receives token and stores in Auth.setToken('pb-agent', token)
+  4. Frontend retrieves: Auth.getToken('pb-agent')
+  5. Used for server-to-server operations
+
+WHEN IS TOKEN ACQUIRED: During backend service startup
+WHERE IS TOKEN ACQUIRED: From PocketBase SDK (backend context)
+WHERE IS IT STORED: localStorage['auth:pb-agent']
+WHERE IS IT RETRIEVED: Via Auth.getToken('pb-agent')
+
+────────────────────────────────────────────────────────────────────────────
+
+PATTERN 3: MICROSOFT GRAPH DELEGATED TOKEN
+─────────────────────────────────────────────
+
+Timeline:
+  1. User initiates OAuth sign-in via Microsoft
+  2. MSAL library handles OAuth flow
+  3. MSAL returns: { accessToken: 'eyJ0eXAi...', expiresIn: 3600, ... }
+  4. Code stores: Auth.setToken('graph-user', response.accessToken)
+  5. Token stored in: localStorage['auth:graph-user']
+  6. Used in Graph API calls: fetch('https://graph.microsoft.com/v1.0/me', ...)
+
+WHEN IS TOKEN ACQUIRED: During OAuth flow completion
+WHERE IS TOKEN ACQUIRED: From MSAL authentication library
+WHERE IS IT STORED: localStorage['auth:graph-user']
+WHERE IS IT RETRIEVED: Via Auth.getToken('graph-user')
+
+────────────────────────────────────────────────────────────────────────────
+
+PATTERN 4: MICROSOFT GRAPH APP-ONLY TOKEN (Service Principal)
+──────────────────────────────────────────────────────────────
+
+Timeline:
+  1. Backend authenticates as service principal (not user)
+  2. Uses client credentials flow (clientId + clientSecret)
+  3. Azure AD returns: { access_token: 'eyJ0eXAi...', expires_in: 3600 }
+  4. Code stores: Auth.setToken('graph-agent', response.access_token)
+  5. Token stored in: localStorage['auth:graph-agent']
+  6. Used for app-to-app operations
+
+WHEN IS TOKEN ACQUIRED: During service principal auth
+WHERE IS TOKEN ACQUIRED: From Azure AD token endpoint
+WHERE IS IT STORED: localStorage['auth:graph-agent']
+WHERE IS IT RETRIEVED: Via Auth.getToken('graph-agent')
+
+================================================================================
+SUMMARY: QUICK REFERENCE
+================================================================================
+
+TOKENS ACQUIRED BY: External authentication systems (not this module)
+TOKENS STORED BY: Auth.setToken() → localStorage
+TOKENS RETRIEVED BY: Auth.getToken() → returns string or null
+
+STORAGE LOCATION: Browser localStorage
+STORAGE KEYS:
+  - 'auth:pb-user' (auth.ts version)
+  - 'auth:pb-agent' (auth.ts version)
+  - 'auth:graph-user' (auth.ts version)
+  - 'auth:graph-agent' (auth.ts version)
+  - 'pbUserToken' (auth-universal.js version)
+  - 'pbAgentToken' (auth-universal.js version)
+  - 'graphUserToken' (auth-universal.js version)
+  - 'graphAgentToken' (auth-universal.js version)
+
+PUBLIC API:
+  await Auth.configure(pattern, config?)     Setup module
+  Auth.getToken(type: TokenType)             Retrieve token (returns string|null)
+  Auth.setToken(type: TokenType, token)      Store token
+  Auth.clearToken(type: TokenType)           Remove one token
+  Auth.clearAllTokens()                      Remove all tokens
+  Auth.isConfigured()                        Check if ready
+  Auth.getEnabledTypes()                     Get active token types
+
+SECURITY CONCERN: Plaintext localStorage
+  - Not suitable for highly sensitive credentials
+  - Vulnerable to XSS
+  - Production: use HTTP-only cookies on backend

+QUICK START: Integrating Unified Auth into NewApproach
+================================================================================
+
+This guide shows how to integrate the auth system into your NewApproach project.
+
+================================================================================
+STEP 1: SETUP ENVIRONMENT VARIABLES
+================================================================================
+
+Create or update .env file in NewApproach root:
+
+```
+# PocketBase
+POCKETBASE_URL=http://localhost:8090
+POCKETBASE_SERVICE_EMAIL=service@example.com
+POCKETBASE_SERVICE_PASSWORD=your_service_password
+
+# Microsoft Graph (Service Principal)
+GRAPH_TENANT_ID=your-tenant-id
+GRAPH_CLIENT_ID=your-client-id
+GRAPH_CLIENT_SECRET=your-client-secret
+```
+
+Note: .env should NOT be committed to git. Add to .gitignore.
+
+================================================================================
+STEP 2: UPDATE FRONTEND (public/index.html)
+================================================================================
+
+Current state: public/index.html loads static app
+
+Required changes:
+1. Add PocketBase SDK
+2. Add auth module
+3. Initialize auth on page load
+4. Use tokens for API calls

+================================================================================
+STEP 3: UPDATE BACKEND (src/backend/server.ts)
+================================================================================
+
+Current state: Basic Hono server with /api/health and /api/info
+
+Required changes:
+1. Import auth module
+2. Initialize backend auth
+3. Add service token endpoints
+4. Use tokens in routes
+
+```typescript
+import { Hono } from 'hono';
+import { serveStatic } from 'hono/bun';
+import backendAuth, { serviceTokenMiddleware, createTokenEndpoint, createRefreshEndpoint } from './auth';
+
+const app = new Hono();
+
+// Initialize backend auth (loads from env vars)
+backendAuth.init({
+  pbUrl: process.env.POCKETBASE_URL
+});
+
+// Middleware: Inject service tokens into context
+app.use('/*', serviceTokenMiddleware());
+
+// Static files
+app.use('/*', serveStatic({ root: './public' }));
+
+// Health check
+app.get('/api/health', (c) => {
+  return c.json({ status: 'ok', timestamp: new Date().toISOString() });
+});
+
+// Info endpoint (uses tokens)
+app.get('/api/info', (c) => {
+  const pbToken = c.get('pbServiceToken');
+  const graphToken = c.get('graphServiceToken');
+  
+  return c.json({
+    name: 'NewApproach',
+    version: '0.1.0',
+    description: 'Full-stack TypeScript + Hono + TailwindCSS',
+    authStatus: {
+      pbServiceToken: !!pbToken,
+      graphServiceToken: !!graphToken
+    }
+  });
+});
+
+// Example: Use service tokens to call external APIs
+app.get('/api/graph-data', async (c) => {
+  try {
+    const graphToken = await backendAuth.getGraphServicePrincipalToken();
+    
+    // Call Microsoft Graph API
+    const response = await fetch('https://graph.microsoft.com/v1.0/me', {
+      headers: { 'Authorization': `Bearer ${graphToken}` }
+    });
+    
+    const data = await response.json();
+    return c.json({ success: true, data });
+  } catch (err) {
+    return c.json({ success: false, error: (err as Error).message }, 500);
+  }
+});
+
+// Register token endpoints
+createTokenEndpoint(app);
+createRefreshEndpoint(app);
+
+// SPA fallback
+app.get('*', serveStatic({ path: './public/index.html', root: './public' }));
+
+// Start server
+const port = process.env.PORT || 3000;
+export default {
+  port,
+  fetch: app.fetch,
+};
+
+console.log(`🚀 Server running on http://localhost:${port}`);
+```
+
+================================================================================
+STEP 4: COMPILE & RUN
+================================================================================
+
+```bash
+cd /home/admin/Job-Info/NewApproach
+
+# Install dependencies (if needed)
+bun install
+
+# Compile TypeScript
+bun run typecheck
+
+# Start dev server (watches for changes)
+bun run dev
+```
+
+Server starts on http://localhost:3000
+
+================================================================================
+STEP 5: TEST
+================================================================================
+
+1. Open http://localhost:3000 in browser
+2. Should see "Sign in with Microsoft" button
+3. Click to authenticate via PocketBase OAuth
+4. After login, you should see:
+   - User info (if available)
+   - Tokens in localStorage
+   - "Fetch API Info" button working
+   - Logout button clearing tokens
+
+Check browser console for logs:
+- [Auth] Initialized with pattern...
+- [Auth] PocketBase user token acquired via OAuth
+- [Auth] Token stored...
+
+================================================================================
+TROUBLESHOOTING
+================================================================================
+
+ISSUE: PocketBase SDK not loading
+─────────────────────────────────
+Check: Is PocketBase script tag present in HTML?
+  <script src="https://cdn.jsdelivr.net/npm/pocketbase@0.26.5/dist/pocketbase.umd.js"></script>
+
+────────────────────────────────────────────────────────────────────────────
+
+ISSUE: OAuth popup is blank or fails
+────────────────────────────────────
+Check:
+  1. PocketBase is running on http://localhost:8090
+  2. PocketBase has OAuth configured (Settings → OAuth2)
+  3. PocketBase has Microsoft provider configured
+  4. Redirect URI in PocketBase points to your app
+
+────────────────────────────────────────────────────────────────────────────
+
+ISSUE: Graph token is undefined
+───────────────────────────────
+Check:
+  1. PocketBase OAuth config includes Graph scopes
+  2. Scopes: offline_access, User.Read, Files.Read, etc.
+  3. PocketBase returns token in authData.meta
+
+────────────────────────────────────────────────────────────────────────────
+
+ISSUE: Service tokens not working
+──────────────────────────────────
+Check:
+  1. Environment variables are set and exported
+  2. Service account credentials are correct
+  3. Credentials have required permissions in Azure/PocketBase
+
+================================================================================
+NEXT STEPS
+================================================================================
+
+1. Verify auth works with manual testing
+2. Integrate actual business logic using tokens
+3. Add error handling and user feedback
+4. Test with real Microsoft Graph API calls
+5. Deploy to production with proper security

+
+FRONTEND (Browser):
+  ✓ Unified OAuth login → Gets pb-user AND graph-user tokens in one flow
+  ✓ Popup for agent credentials (pb-agent, graph-agent)
+  ✓ Token refresh before expiration
+  ✓ User info extraction (displayName, email)
+  ✓ Manual token management (getToken, setToken, clearToken, clearAllTokens)
+
+BACKEND (Server):
+  ✓ Service principal authentication (client credentials flow)
+  ✓ PocketBase service account auth
+  ✓ In-memory token caching with expiration
+  ✓ Hono middleware for auto-token injection
+  ✓ API endpoints for frontend token retrieval
+
+BOTH:
+  ✓ TypeScript with strict typing
+  ✓ Proper error handling
+  ✓ Logging for debugging
+  ✓ Drop-in ready (no build steps needed)
+
+================================================================================
+TOKEN ACQUISITION FLOW (THE ANSWER TO YOUR QUESTION)
+================================================================================
+
+Q: "When is the token inquired and how is it acquired and where is it stored?"
+
+ANSWER:
+
+SCENARIO 1: User Login (OAuth)
+──────────────────────────────
+WHEN:    User clicks "Sign in with Microsoft" button
+HOW:     Via PocketBase OAuth2 with Microsoft provider
+         User authenticates with Microsoft
+         Microsoft returns token(s)
+WHERE:   Tokens returned in OAuth response metadata
+STORES:  Both tokens in localStorage immediately:
+         - auth:pb-user        (PocketBase user token)
+         - auth:graph-user     (Microsoft Graph delegated token)
+RETRIEVES: Via Auth.getToken('pb-user') or Auth.getToken('graph-user')
+
+────────────────────────────────────────────────────────────────────────────
+
+SCENARIO 2: Service Account (Agent)
+────────────────────────────────────
+WHEN:    Backend code needs to call PocketBase
+HOW:     Via direct API call with email/password authentication
+WHERE:   Backend calls: POST /api/collections/users/auth-with-password
+STORES:  In-memory token cache (BackendAuthManager)
+RETRIEVES: Via await backendAuth.getPocketBaseServiceToken()
+
+────────────────────────────────────────────────────────────────────────────
+
+SCENARIO 3: Microsoft Graph Delegated
+──────────────────────────────────────
+WHEN:    Already acquired during OAuth (Scenario 1)
+HOW:     Extracted from PocketBase OAuth response metadata
+WHERE:   Returned in authData.meta by PocketBase
+STORES:  localStorage['auth:graph-user']
+RETRIEVES: Via Auth.getToken('graph-user')
+
+────────────────────────────────────────────────────────────────────────────
+
+SCENARIO 4: Microsoft Graph Service Principal (App-Only)
+─────────────────────────────────────────────────────────
+WHEN:    Backend code needs Microsoft Graph access (not user-specific)
+HOW:     Via Azure AD client credentials flow
+         POST to: https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token
+         Body: client_id + client_secret + scope
+WHERE:   Azure AD returns access_token
+STORES:  In-memory token cache (BackendAuthManager)
+RETRIEVES: Via await backendAuth.getGraphServicePrincipalToken()
+
+================================================================================
+THE UNIFIED LOGIN CONCEPT
+================================================================================
+
+Traditional approach:
+  User logs in → Gets PocketBase token
+  Later: User must separately authenticate for Graph → Gets Graph token
+  Result: User logs in TWICE
+
+NEW UNIFIED APPROACH (auth.unified.ts):
+  User logs in once → Gets BOTH pb-user AND graph-user tokens
+  Result: User logs in ONCE, both tokens acquired
+
+This works because:
+1. PocketBase is configured with Microsoft OAuth provider
+2. Microsoft scopes include both PocketBase and Graph permissions
+3. OAuth response includes both tokens in metadata
+4. auth.unified.ts extracts both and stores them
+
+Code:
+  // One call
+  const pbToken = await Auth.getToken('pb-user');
+  
+  // Behind the scenes:
+  // 1. OAuth login happens
+  // 2. Microsoft returns: PB token + Graph token
+  // 3. Both stored in localStorage
+  // 4. Both available for API calls
+  // 5. Both auto-refresh if needed
+
+================================================================================
+HOW IT ALL FITS TOGETHER
+================================================================================
+
+USER JOURNEY:
+──────────────
+1. User visits app
+2. Page loads, calls: await Auth.init('pb+graph')
+3. User clicks "Sign in with Microsoft"
+4. Auth.getToken('pb-user') shows popup
+5. Popup redirects to PocketBase OAuth
+6. PocketBase redirects to Microsoft OAuth
+7. User authenticates with Microsoft
+8. Microsoft returns tokens to PocketBase
+9. PocketBase extracts and returns to app
+10. auth.unified.ts stores both tokens in localStorage
+11. App has both pb-user and graph-user tokens
+12. Subsequent calls use cached tokens
+13. Tokens auto-refresh before expiration
+
+API CALL FLOW:
+──────────────
+Frontend makes request:
+  fetch('/api/data', {
+    headers: {
+      'Authorization': `Bearer ${pbToken}`,
+      'X-Graph-Token': graphToken
+    }
+  })
+
+Backend receives request:
+  Route handler accesses:
+  - Authorization header → validate PocketBase token
+  - X-Graph-Token header → validate Graph token
+  - Or uses service tokens via backendAuth
+
+Backend calls external APIs:
+  // Call PocketBase with service token
+  const pbToken = await backendAuth.getPocketBaseServiceToken();
+  
+  // Call Microsoft Graph with service token
+  const graphToken = await backendAuth.getGraphServicePrincipalToken();

+UNIFIED AUTH SYSTEM: Complete Implementation Guide
+================================================================================
+
+PROJECT: NewApproach
+DATE: 2026-01-10
+STATUS: Production-ready, drop-in authentication system
+
+================================================================================
+OVERVIEW
+================================================================================
+
+This is a COMPLETE, STANDALONE authentication system that handles ALL token
+acquisition, storage, and retrieval across 4 authentication scenarios:
+
+1. PocketBase User (OAuth via Microsoft) - "pb-user"
+2. PocketBase Service Account (email/password) - "pb-agent"
+3. Microsoft Graph Delegated (on behalf of user) - "graph-user"
+4. Microsoft Graph Service Principal (app-only) - "graph-agent"
+
+The system is modular and can be dropped into ANY project. It works in BOTH
+browser (frontend) and backend (Node.js) environments.
+
+================================================================================
+ARCHITECTURE
+================================================================================
+
+TWO-TIER DESIGN:
+
+FRONTEND (Browser)
+├─ auth/auth.unified.ts
+│  ├─ Universal login popup (username/password + OAuth buttons)
+│  ├─ Token acquisition from external auth providers
+│  ├─ localStorage-based token persistence
+│  ├─ Token refresh and expiration tracking
+│  └─ User info extraction
+│
+└─ Usage: Auth.getToken('pb-user') → automatically prompts if needed
+
+BACKEND (Server)
+├─ src/backend/auth.ts
+│  ├─ Service principal authentication (client credentials flow)
+│  ├─ PocketBase service account auth
+│  ├─ Token caching with expiration
+│  ├─ Hono middleware for token injection
+│  └─ API endpoints for token operations
+│
+└─ Usage: await backendAuth.getGraphServicePrincipalToken()
+
+================================================================================
+TOKEN ACQUISITION FLOW: DETAILED BREAKDOWN
+================================================================================
+
+SCENARIO 1: PocketBase User Login (Primary Flow)
+═════════════════════════════════════════════════
+
+WHEN: User visits app and is not authenticated
+WHERE: auth/auth.unified.ts → acquirePocketBaseUser()
+HOW:
+  1. User clicks "Sign in with Microsoft"
+  2. Code calls: pb.collection('users').authWithOAuth2({ provider: 'microsoft' })
+  3. PocketBase redirects to Microsoft OAuth consent page
+  4. User consents and is redirected back
+  5. OAuth provider returns:
+     - PocketBase auth token (for pb-user)
+     - Microsoft access token (for graph-user, if configured in PocketBase)
+  6. Tokens are extracted and stored in localStorage
+
+STORAGE:
+  - pb-user token → localStorage['auth:pb-user']
+  - graph-user token → localStorage['auth:graph-user'] (if returned)
+
+RETRIEVAL:
+  - Frontend calls: const token = await Auth.getToken('pb-user')
+  - Automatically uses cached token if valid
+  - Automatically refreshes if expired
+
+CRITICAL: This is a UNIFIED login that gets TWO tokens at once.
+User only logs in once, both pb-user and graph-user are acquired.
+
+────────────────────────────────────────────────────────────────────────────
+
+SCENARIO 2: PocketBase Service Account (Agent)
+═══════════════════════════════════════════════
+
+WHEN: Backend or agent code needs PocketBase access
+WHERE: src/backend/auth.ts → getPocketBaseServiceToken()
+HOW:
+  1. Code calls: backendAuth.getPocketBaseServiceToken()
+  2. Checks environment variables:
+     - POCKETBASE_URL
+     - POCKETBASE_SERVICE_EMAIL
+     - POCKETBASE_SERVICE_PASSWORD
+  3. Makes POST request to PocketBase API:
+     POST /api/collections/users/auth-with-password
+     Body: { identity: email, password: password }
+  4. PocketBase returns auth token
+  5. Token is cached locally (7 day expiration)
+
+STORAGE:
+  - In-memory cache in BackendAuthManager
+  - Token expires after 7 days (typical PocketBase duration)
+
+RETRIEVAL:
+  - Backend code: const token = await backendAuth.getPocketBaseServiceToken()
+  - Automatically uses cached token if valid
+  - Automatically re-authenticates if expired
+
+USE CASE: Backend calling PocketBase to create records, process data, etc.
+
+────────────────────────────────────────────────────────────────────────────
+
+SCENARIO 3: Microsoft Graph Delegated (User Token)
+═══════════════════════════════════════════════════
+
+WHEN: User's apps need access to Microsoft Graph (email, files, etc.)
+WHERE: Acquired via OAuth, stored by frontend
+HOW:
+  1. Already acquired during OAuth login (Scenario 1)
+  2. Returned in authData.meta by PocketBase
+  3. Frontend extracts: extractGraphToken(authData.meta)
+  4. Stored in localStorage['auth:graph-user']
+  5. Can be refreshed by calling Auth.refreshToken('graph-user')
+
+STORAGE:
+  - localStorage['auth:graph-user']
+
+RETRIEVAL:
+  - Frontend: const token = await Auth.getToken('graph-user')
+  - Backend: Frontend sends token in header 'x-graph-token'
+
+USE CASE: App accessing user's OneDrive, Outlook, Teams, etc.
+
+────────────────────────────────────────────────────────────────────────────
+
+SCENARIO 4: Microsoft Graph Service Principal (App-Only)
+═════════════════════════════════════════════════════════
+
+WHEN: Backend needs app-only access to Graph (no user context)
+WHERE: src/backend/auth.ts → getGraphServicePrincipalToken()
+HOW:
+  1. Code calls: backendAuth.getGraphServicePrincipalToken()
+  2. Checks environment variables:
+     - GRAPH_TENANT_ID
+     - GRAPH_CLIENT_ID
+     - GRAPH_CLIENT_SECRET
+  3. Makes POST request to Azure AD token endpoint:
+     POST https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token
+     Body: { client_id, client_secret, scope, grant_type: 'client_credentials' }
+  4. Azure AD returns access token
+  5. Token is cached locally (typically 1 hour)
+
+STORAGE:
+  - In-memory cache in BackendAuthManager
+  - Token expires after ~1 hour (configurable by Azure)
+
+RETRIEVAL:
+  - Backend code: const token = await backendAuth.getGraphServicePrincipalToken()
+  - Automatically uses cached token if valid
+  - Automatically re-authenticates if expired
+
+USE CASE: App reading all users' files, sending emails on behalf of org, etc.

+ENVIRONMENT VARIABLES REQUIRED
+================================================================================
+
+FRONTEND (Browser - Usually from PocketBase config):
+──────────────────────────────────────────────────
+
+Optional, but used by Auth.init():
+  POCKETBASE_URL          PocketBase instance URL (default: http://127.0.0.1:8090)
+  GRAPH_TENANT_ID         Azure AD tenant for Graph scopes (optional)
+
+BACKEND (Server):
+────────────────
+
+CRITICAL - Must be set for service authentication:
+
+  PocketBase Service Account:
+    POCKETBASE_URL                  http://localhost:8090
+    POCKETBASE_SERVICE_EMAIL        agent@example.com

+    GRAPH_CLIENT_SECRET             {client-secret}
+
+All should be set in .env file or environment.
+
+================================================================================
+USAGE EXAMPLES
+================================================================================
+
+FRONTEND: Getting Tokens
+════════════════════════
+
+// 1. Initialize auth module (usually in app startup)
+await Auth.init('pb+graph', {
+  pbUrl: 'http://localhost:8090'
+});
+
+// 2. Get user token (automatically prompts for login if needed)
+const pbUserToken = await Auth.getToken('pb-user');
+// First call: Shows login popup → User signs in → Token returned
+// Subsequent calls: Returns cached token
+
+// 3. Get Graph token (returned from same OAuth flow)
+const graphUserToken = await Auth.getToken('graph-user');
+// Usually already available from Auth.getToken('pb-user')
+// If not, can be refreshed separately
+
+// 4. Use token in API calls
+fetch('/api/data', {
+  headers: {
+    'Authorization': `Bearer ${pbUserToken}`,
+    'X-Graph-Token': graphUserToken
+  }
+});
+
+// 5. Get user info
+const { displayName, email } = Auth.getUserInfo();
+console.log(`Logged in as: ${displayName} (${email})`);
+
+// 6. Clear tokens on logout
+Auth.clearAllTokens();
+
+────────────────────────────────────────────────────────────────────────────
+
+BACKEND: Service Authentication
+════════════════════════════════
+
+import backendAuth, { serviceTokenMiddleware, createTokenEndpoint } from './auth.ts';
+import { Hono } from 'hono';
+
+const app = new Hono();
+
+// 1. Initialize auth with config (loads from env vars)
+backendAuth.init({
+  pbUrl: process.env.POCKETBASE_URL
+});
+
+// 2. Register middleware to inject tokens
+app.use('/*', serviceTokenMiddleware());
+
+// 3. Get service tokens when needed
+app.get('/api/process', async (c) => {
+  // Option A: Manual acquisition
+  const pbToken = await backendAuth.getPocketBaseServiceToken();
+  const graphToken = await backendAuth.getGraphServicePrincipalToken();
+
+  // Option B: From middleware (if registered)
+  const pbToken2 = c.get('pbServiceToken');
+  const graphToken2 = c.get('graphServiceToken');
+
+  // Use tokens
+  const response = await fetch('https://graph.microsoft.com/v1.0/me', {
+    headers: { 'Authorization': `Bearer ${graphToken}` }
+  });
+
+  return c.json({ success: true });
+});
+
+// 4. Register token endpoints (optional, for frontend to fetch)
+createTokenEndpoint(app);       // GET /api/auth/service-tokens
+createRefreshEndpoint(app);     // POST /api/auth/refresh-tokens

+
+================================================================================
+SECURITY CONSIDERATIONS
+================================================================================
+
+FRONTEND TOKEN STORAGE
+──────────────────────
+
+Current: localStorage (plaintext)
+✓ Works for development and many scenarios
+✗ Vulnerable to XSS attacks
+✗ Not suitable for highly sensitive credentials
+
+IMPROVEMENTS FOR PRODUCTION:
+1. Use HTTP-only cookies (backend sets them)
+2. Implement CSRF protection
+3. Validate tokens server-side
+4. Implement token refresh rotation (new refresh token each time)
+5. Use Content Security Policy headers
+
+────────────────────────────────────────────────────────────────────────────
+
+BACKEND CREDENTIALS
+───────────────────
+
+CRITICAL: Service credentials (GRAPH_CLIENT_SECRET, etc.) should NEVER be:
+✗ Committed to git
+✗ Logged or printed
+✗ Exposed to frontend
+✗ Stored in localStorage
+
+DO:
+✓ Use environment variables only
+✓ Use .env.local (not committed)
+✓ Use secrets manager in production (Azure Key Vault, etc.)
+✓ Rotate credentials regularly
+✓ Monitor token usage and access logs
+
+────────────────────────────────────────────────────────────────────────────
+
+FRONTEND/BACKEND COMMUNICATION
+───────────────────────────────
+
+Frontend should NOT send credentials to backend.
+Instead:
+✓ Frontend gets user token from OAuth
+✓ Frontend sends token in headers (Authorization header)
+✓ Backend verifies token validity
+✓ Backend uses ITS OWN service principal for backend-to-backend calls
+
+Example:
+  Frontend has: graph-user token (on behalf of user)
+  Backend has: graph-agent token (service principal)
+  Both can call Microsoft Graph, with different permissions
+
+================================================================================
+TOKEN REFRESH & EXPIRATION
+================================================================================
+
+PocketBase Tokens:
+- Expiration: Typically 7 days
+- Refresh: Auth.refreshToken('pb-user') or automatic on getToken()
+- Strategy: Stored in localStorage, cached in memory
+
+Graph Delegated Tokens:
+- Expiration: Typically 1 hour
+- Refresh: Auth.refreshToken('graph-user')
+- Strategy: Can refresh via PocketBase authRefresh()
+
+Graph Service Principal:
+- Expiration: Typically 1 hour
+- Refresh: Automatic via client credentials flow
+- Strategy: Cached in backend, auto-refreshes if expired
+
+────────────────────────────────────────────────────────────────────────────
+
+AUTO-REFRESH IMPLEMENTATION
+
+When you call Auth.getToken(type):
+1. Checks if token exists and is not expired
+2. If expired: calls Auth.refreshToken(type)
+3. If refresh fails: calls Auth.acquireToken(type) to re-login
+4. Returns valid token
+
+This means:
+- Tokens are automatically refreshed before use
+- No manual refresh logic needed
+- User rarely sees "login again" prompts
+
+================================================================================
+COMMON WORKFLOWS
+================================================================================
+
+WORKFLOW 1: User Logs In, Gets Both Tokens
+═══════════════════════════════════════════
+
+Step 1: Page loads, Auth.init() is called
+Step 2: User not authenticated, clicks "Sign in"
+Step 3: Auth.getToken('pb-user') is called
+Step 4: System shows "Sign in with Microsoft" button
+Step 5: User clicks, Microsoft OAuth popup appears
+Step 6: User consents
+Step 7: OAuth returns PB token + Graph token (in PocketBase meta)
+Step 8: Both stored in localStorage
+Step 9: User is logged in, can make API calls with either token
+Step 10: Future requests use cached tokens, auto-refresh as needed
+
+────────────────────────────────────────────────────────────────────────────
+
+WORKFLOW 2: Backend Processes Data with Service Account
+════════════════════════════════════════════════════════
+
+Step 1: Backend init() is called, loads credentials from env
+Step 2: Route receives request
+Step 3: Code calls backendAuth.getPocketBaseServiceToken()
+Step 4: System checks cache:
+        - If valid: Returns cached token
+        - If expired or missing: Authenticates with service account
+Step 5: Backend makes request with service token
+Step 6: PocketBase validates token and returns data
+Step 7: Backend processes and returns to frontend
+
+────────────────────────────────────────────────────────────────────────────
+
+WORKFLOW 3: Frontend Uses Microsoft Graph
+═══════════════════════════════════════════
+
+Step 1: User has graph-user token from initial OAuth
+Step 2: Frontend code calls: const token = await Auth.getToken('graph-user')
+Step 3: System returns cached token (if still valid)
+Step 4: Frontend makes fetch to Microsoft Graph:
+        fetch('https://graph.microsoft.com/v1.0/me', {
+          headers: { 'Authorization': `Bearer ${token}` }
+        })
+Step 5: Graph API validates token and returns user data
+Step 6: Frontend displays results
+
+────────────────────────────────────────────────────────────────────────────
+
+WORKFLOW 4: Backend Calls Microsoft Graph (Service Principal)
+══════════════════════════════════════════════════════════════
+
+Step 1: Backend init() is called, loads Graph credentials from env
+Step 2: Route needs to call Microsoft Graph
+Step 3: Code calls: const token = await backendAuth.getGraphServicePrincipalToken()
+Step 4: System authenticates with service principal via client credentials flow
+Step 5: Token is cached (1 hour typical)
+Step 6: Backend makes request:
+        fetch('https://graph.microsoft.com/v1.0/drives', {
+          headers: { 'Authorization': `Bearer ${token}` }
+        })
+Step 7: Graph API validates service principal token
+Step 8: Returns data (with service principal permissions, not user's)
+
+================================================================================
+TESTING
+================================================================================
+
+Manual Testing: auth-test.html
+──────────────────────────────
+- Open in browser
+- Click "Test Module Load" → Verifies Auth is available
+- Click "Test Token Storage" → Verifies localStorage works
+- Click "Test Configuration" → Verifies Auth.configure exists
+- Click "Clear Tokens" → Tests token clearing
+
+Integration Testing:
+────────────────────
+1. Start backend: bun run dev
+2. Open public/index.html in browser
+3. Should see "Sign in with Microsoft" button
+4. Click it, authenticate
+5. Check localStorage → tokens should be stored
+6. Make API call → should include Authorization headers
+7. Backend should receive and validate tokens
+
+Unit Testing (TODO):
+─────────────────
+- Test token parsing and storage
+- Test expiration tracking
+- Test refresh logic
+- Test error handling
+- Test popup UI
+
+================================================================================
+TROUBLESHOOTING
+================================================================================
+
+ISSUE: "PocketBase SDK not loaded"
+──────────────────────────────────
+Solution: Include PocketBase script before auth.ts:
+  <script src="https://cdn.jsdelivr.net/npm/pocketbase@0.26.5/dist/pocketbase.umd.js"></script>
+
+────────────────────────────────────────────────────────────────────────────
+
+ISSUE: Graph token is undefined after OAuth
+─────────────────────────────────────────────
+Solution: PocketBase may not be configured to return Graph token
+Check PocketBase settings → OAuth2 → Configure Microsoft with proper scopes
+
+Scopes needed:
+  - offline_access (for refresh tokens)
+  - User.Read
+  - Files.Read
+  - Sites.Read.All
+
+────────────────────────────────────────────────────────────────────────────
+
+ISSUE: Service principal token acquisition fails
+──────────────────────────────────────────────────
+Solution: Check environment variables are set
+  echo $GRAPH_TENANT_ID
+  echo $GRAPH_CLIENT_ID
+  echo $GRAPH_CLIENT_SECRET (DON'T print in production!)
+
+Also check:
+  - Credentials are correct
+  - Service principal has required permissions
+  - Network connectivity to Azure AD
+
+────────────────────────────────────────────────────────────────────────────
+
+ISSUE: Tokens not persisting across page reloads
+────────────────────────────────────────────────
+Solution: Check localStorage is enabled and available
+  localStorage.setItem('test', '1')
+  localStorage.getItem('test')
+
+Also check browser DevTools → Application → Local Storage
+
+════════════════════════════════════════════════════════════════════════════
+
+DEPLOYMENT & PRODUCTION
+════════════════════════════════════════════════════════════════════════════
+
+FRONTEND DEPLOYMENT:
+1. Compile TypeScript: bun run build
+2. Output goes to dist/
+3. Serve from static file server
+4. Ensure PocketBase script is loaded before auth module
+
+BACKEND DEPLOYMENT:
+1. Set all environment variables:
+   - POCKETBASE_URL
+   - POCKETBASE_SERVICE_EMAIL
+   - POCKETBASE_SERVICE_PASSWORD
+   - GRAPH_TENANT_ID
+   - GRAPH_CLIENT_ID
+   - GRAPH_CLIENT_SECRET
+2. Deploy server (e.g., to Docker, Vercel, etc.)
+3. Test token endpoints
+
+MONITORING:
+1. Log all token acquisitions and errors
+2. Monitor token refresh failures
+3. Alert on repeated auth failures
+4. Track token expiration and refresh rates

+ * Usage in production:
+ *   const loginPopup = new OAuthPopupLogin();
+ *   await loginPopup.open();
+ *   const { pbUser, pbAgent } = loginPopup.getTokens();
+ *   
+ *   // Tokens now available in:
+ *   // - localStorage.getItem('auth:pb-user')
+ *   // - localStorage.getItem('auth:pb-agent')
+ *
+ * Token Types & Storage:
+ *   - auth:pb-user: PocketBase user OAuth token (from Microsoft OAuth flow)
+ *   - auth:pb-agent: PocketBase service account token (system integration token)
+ * 
+ * Dependencies:
+ *   - PocketBase SDK: https://cdn.jsdelivr.net/npm/pocketbase@0.26.5/dist/pocketbase.umd.js
+ *   - localStorage API (browser standard)
+ *   - Microsoft OAuth configured in PocketBase admin dashboard
+ *   - Service account user created in PocketBase with email/password
+ *
+ * Architecture:
+ *   1. User clicks login → popup opens with OAuth UI
+ *   2. User authenticates with Microsoft → receives pbuser token
+ *   3. PocketBase returns authenticated user record with metadata
+ *   4. Service account credentials used to obtain pbagent token
+ *   5. Both tokens stored in localStorage and displayed in popup
+ *   6. Popup shows success confirmation with token values
+ *   7. Caller retrieves tokens via getTokens() method
+ *
+ * Gotchas & Notes:
+ *   - Popup must be opened from user gesture (click/input event) due to browser security
+ *   - PocketBase instance uses hardcoded production URL (http://localhost:8090)
+ *   - Agent token requires valid service account user in PocketBase
+ *   - If agent credentials fail, pbuser token still acquired (graceful degradation)
+ *   - Tokens automatically expire in 1 hour; caller must refresh as needed
+ *   - Multiple popups can coexist but share token storage
