- Implemented OAuth endpoints (providers list, authorization, callback, linked accounts management).
- Added UI translations for OAuth workflows (auth process messages, linked accounts management).
- Extended TypeScript types and React hooks to support OAuth features.
- Updated app configuration with OAuth-specific settings and provider details.
- Introduced skeleton implementations for authorization and token endpoints in provider mode.
- Included unit test and integration hooks for OAuth capabilities.
- Deleted `admin.ts`, `auth.ts`, and `users.ts` MSW handler files to streamline demo mode setup.
- Updated demo credentials logic in `DemoCredentialsModal` and `DemoModeBanner` for stronger password requirements (≥12 characters).
- Refined documentation in `CLAUDE.md` to align with new credential standards and auto-generated MSW workflows.
- Integrated Mock Service Worker (MSW) for frontend-only demo mode, allowing API call interception without requiring a backend.
- Added `DemoModeBanner` component to indicate active demo mode and display demo credentials.
- Enhanced configuration with `DEMO_MODE` flag and demo credentials for user and admin access.
- Updated ESLint configuration to exclude MSW-related files from linting and coverage.
- Created comprehensive `DEMO_MODE.md` documentation for setup and usage guidelines, including deployment instructions and troubleshooting.
- Updated package dependencies to include MSW and related libraries.
- Introduced comprehensive tests for `RegisterForm`, `PasswordResetRequestForm`, and `PasswordResetConfirmForm` covering successful submissions, validation errors, and API error handling.
- Refactored forms to handle unexpected errors gracefully and improve test coverage for edge cases.
- Updated `crypto` and `storage` modules with robust error handling for storage issues and encryption key management.
- Removed unused `axios-mock-adapter` dependency for cleaner dependency management.
- Introduced Web Crypto API polyfills (`@peculiar/webcrypto`) for Node.js to enable SSR-safe cryptography utilities.
- Added Jest setup file for global mocks (e.g., `localStorage`, `sessionStorage`, and `TextEncoder/Decoder`).
- Enhanced token validation behavior in `storage` tests to reject incomplete tokens.
- Replaced runtime configuration validation with clamping using `parseIntSafe` constraints for improved reliability.
- Updated `package.json` and `package-lock.json` to include new dependencies (`@peculiar/webcrypto` and related libraries).
- Centralized and refactored configuration management (`config`) with runtime validation for environment variables.
- Introduced utilities for secure token storage, including AES-GCM encryption and fallback handling.
- Enhanced `authStore` state management with token validation, secure persistence, and initialization from storage.
- Modularized authentication utilities and updated export structure for better maintainability.
- Improved error handling, input validation, and added detailed comments for enhanced clarity.
