🔴 Plaintext password storage and comparison enables credential theft
Passwords are stored in plaintext in the SQLite database (DatabaseInitializer.cs:145-147) and compared directly via user.Password != loginDto.Password. If the database file is ever accessed (it's a local .db file), all credentials are immediately exposed. The Register endpoint at SrushtiAPI/Controllers/AuthController.cs:55 also stores the password in plaintext. Passwords should be hashed (e.g., with bcrypt) before storage and compared using a constant-time hash comparison.

🔴 Unauthenticated Register endpoint allows privilege escalation to admin
The Register endpoint has no [Authorize] attribute and directly accepts the Role field from the client via RegisterDto.Role (SrushtiAPI/DTOs/LoginDto.cs:21). Any anonymous user can POST to /api/auth/register with {"role": "admin", ...} to create an admin account, granting themselves full administrative privileges. The role should either be forced to "user" server-side, or the endpoint should require admin authorization.
Prompt for agents
In SrushtiAPI/Controllers/AuthController.cs, the Register method at lines 46-63 should either: (1) Force the role to 'user' by ignoring registerDto.Role and hardcoding user.Role = "user", or (2) Add [Authorize(Roles = "admin")] to the Register method so only admins can create new users with arbitrary roles. Option 1 is simpler; Option 2 aligns with the admin-only user registration in the frontend.

🔴 GetUsers endpoint exposes user data without authentication
The GetUsers method at line 39 has no [Authorize] attribute, and the AuthController class itself also lacks one. This means any unauthenticated user can call GET /api/auth/users to retrieve the full list of users (IDs, usernames, full names, emails, and roles). All other data controllers (DashboardController, EmployeeController, etc.) use [Authorize] at the class level, making this an inconsistency.

🔴 Frontend API base URL port mismatch prevents backend communication
The Angular frontend's environment.ts configures apiBaseUrl as http://localhost:5000/api, but the .NET API's launchSettings.json:17 configures the application to run on http://localhost:5128. This port mismatch means all API calls from the frontend will fail with connection refused errors, making the application non-functional in development.

🟡 Stock add form validation allows quantity of 0 to be submitted
In add-stock.component.ts:44, the quantity validation uses this.stockEntry.quantity < 0 which allows a stock entry with quantity 0 to pass validation and be submitted. All other add-form components (sales, purchase, returns) use the !this.stockEntry.quantity falsy check which correctly blocks 0. A stock entry with 0 quantity is semantically invalid and would result in a totalValue of 0.

Summary
Adds a new Angular 21 standalone project (
srushtiUI/) implementing a Sales & Purchase Management System with Employee Management and Payroll, backed by a .NET Core 8.0 Web API (SrushtiAPI/) using Dapper ORM and SQLite for persistent data storage. Role-based access control via JWT authentication.Frontend Features (Angular 21):

Authorizationheader — triggering an infinite redirect loop (auth guard still sawcurrentUserSubjectas truthy because onlylocalStoragewas cleared, not the BehaviorSubject). Fix:authService.logout()(which clears bothlocalStorageandcurrentUserSubject) instead of manually removing localStorage itemsisRedirectingmodule-level flag to debounce — only the first 401 triggers the logout + redirect; subsequent 401s from parallel requests are silently caught/auth/loginrequests from the 401 handler to avoid clearing credentials during login failuressubscribe()calls inDashboardComponent.loadDashboardData()now use{ next, error }observer pattern with empty error handlers, preventing unhandled Observable errors from propagating when the API is unreachable or the token is being clearedReview & Testing Checklist for Human
isRedirectingflag resets correctly — The flag resets insiderouter.navigate('/login').then(...). If the navigation promise were to reject (unlikely but possible), the flag could get stuck astrue, permanently preventing 401 handling. Check edge cases like navigating while already on/loginAuthService. The.spec.tstest files may not have been updated to useHttpClientTestingModule/HttpTestingController.

Confirm this doesn't cause runtime errors in list components after deletionappsettings.json,GET /api/auth/usersendpoint is unauthenticated. Acceptable for demo onlyRecommended test plan:
cd SrushtiAPI && dotnet run --urls "http://localhost:5000"(starts API with SQLite)cd srushtiUI && npm install && npx ng serve --port 4200(starts Angular)http://localhost:4200, log in asadmin/admin123localhost:5000/api/*withAuthorization: BearerheaderNotes
GET /api/dashboardendpoint — functional but suboptimalerror: () => {}) — errors are silently swallowed so the dashboard shows 0s rather than crashing. This means a misconfigured API will show zeros with no visible error indication to the userisRedirectingflag is module-level mutable state (not instance-scoped), which is intentional for the functional interceptor pattern but may complicate unit testingAddPayrollComponent.onEmployeeSelect()xlsxlibraryadmin/admin123(admin role),user/user123(user role) — seeded byDatabaseInitializerhttp://localhost:5000/swaggerwhen running in Development modeLink to Devin session: https://partner-workshops.devinenterprise.com/sessions/ed44f620b76842acbad64d503a469b8d
