+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright notice to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. When redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

 Always place private methods to the bottom of file
 
-Code should look like:
+**This rule applies to ALL Go files including tests, services, controllers, repositories, etc.**
 
-type SomeService struct {
-    func PublicMethod(...) ...
+In Go, exported (public) functions/methods start with uppercase letters, while unexported (private) ones start with lowercase letters.
 
-    func privateMethod(...) ...
-}
+## Structure Order:
+
+1. Type definitions and constants
+2. Public methods/functions (uppercase)
+3. Private methods/functions (lowercase)
+
+## Examples:
+
+### Service with methods:
+
+```go
+type UserService struct {
+    repository *UserRepository
+}
+
+// Public methods first
+func (s *UserService) CreateUser(user *User) error {
+    if err := s.validateUser(user); err != nil {
+        return err
+    }
+    return s.repository.Save(user)
+}
+
+func (s *UserService) GetUser(id uuid.UUID) (*User, error) {
+    return s.repository.FindByID(id)
+}
+
+// Private methods at the bottom
+func (s *UserService) validateUser(user *User) error {
+    if user.Name == "" {
+        return errors.New("name is required")
+    }
+    return nil
+}
+```
+
+### Package-level functions:
+
+```go
+package utils
+
+// Public functions first
+func ProcessData(data []byte) (Result, error) {
+    cleaned := sanitizeInput(data)
+    return parseData(cleaned)
+}
+
+func ValidateInput(input string) bool {
+    return isValidFormat(input) && checkLength(input)
+}
+
+// Private functions at the bottom
+func sanitizeInput(data []byte) []byte {
+    // implementation
+}
+
+func parseData(data []byte) (Result, error) {
+    // implementation
+}
+
+func isValidFormat(input string) bool {
+    // implementation
+}
+
+func checkLength(input string) bool {
+    // implementation
+}
+```
+
+### Test files:
+
+```go
+package user_test
+
+// Public test functions first
+func Test_CreateUser_ValidInput_UserCreated(t *testing.T) {
+    user := createTestUser()
+    result, err := service.CreateUser(user)
+
+    assert.NoError(t, err)
+    assert.NotNil(t, result)
+}
+
+func Test_GetUser_ExistingUser_ReturnsUser(t *testing.T) {
+    user := createTestUser()
+    // test implementation
+}
+
+// Private helper functions at the bottom
+func createTestUser() *User {
+    return &User{
+        Name:  "Test User",
+        Email: "test@example.com",
+    }
+}
+
+func setupTestDatabase() *Database {
+    // setup implementation
+}
+```
+
+### Controller example:
+
+```go
+type ProjectController struct {
+    service *ProjectService
+}
+
+// Public HTTP handlers first
+func (c *ProjectController) CreateProject(ctx *gin.Context) {
+    var request CreateProjectRequest
+    if err := ctx.ShouldBindJSON(&request); err != nil {
+        c.handleError(ctx, err)
+        return
+    }
+    // handler logic
+}
+
+func (c *ProjectController) GetProject(ctx *gin.Context) {
+    projectID := c.extractProjectID(ctx)
+    // handler logic
+}
+
+// Private helper methods at the bottom
+func (c *ProjectController) handleError(ctx *gin.Context, err error) {
+    ctx.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
+}
+
+func (c *ProjectController) extractProjectID(ctx *gin.Context) uuid.UUID {
+    return uuid.MustParse(ctx.Param("projectId"))
+}
+```
+
+## Key Points:
+
+- **Exported/Public** = starts with uppercase letter (CreateUser, GetProject)
+- **Unexported/Private** = starts with lowercase letter (validateUser, handleError)
+- This improves code readability by showing the public API first
+- Private helpers are implementation details, so they go at the bottom
+- Apply this rule consistently across ALL Go files in the project

-Do not write obvious comments.
-Write meaningful code, give meaningful names
+
+## Comment Guidelines
+
+1. **No obvious comments** - Don't state what the code already clearly shows
+2. **Functions and variables should have meaningful names** - Code should be self-documenting
+3. **Comments for unclear code only** - Only add comments when code logic isn't immediately clear
+
+## Key Principles:
+
+- **Code should tell a story** - Use descriptive variable and function names
+- **Comments explain WHY, not WHAT** - The code shows what happens, comments explain business logic or complex decisions
+- **Prefer refactoring over commenting** - If code needs explaining, consider making it clearer instead
+- **API documentation is required** - Swagger comments for all HTTP endpoints are mandatory
+- **Complex algorithms deserve comments** - Mathematical formulas, business rules, or non-obvious optimizations
+
+Example of useless comment:
+
+1.
+
+```sql
+// Create projects table
+CREATE TABLE projects (
+    id                    UUID PRIMARY KEY DEFAULT gen_random_uuid(),

+When applying changes, do not forget to refactor old code.
+
+You can shortify, make more readable, improve code quality, etc.
+Common logic can be extracted to functions, constants, files, etc.
+
+After each large change with more than ~50-100 lines of code - always run `make lint` (from backend root folder).

-Write tests names in the format:
 
-Test_WhatWeDo_WhatWeExpect
+After writing tests, always launch them and verify that they pass.
 
-Example:
-- Test_TestConnection_ConnectionSucceeds
-- Test_SaveNewStorage_StorageReturnedViaGet
+## Test Naming Format
+
+Use these naming patterns:
+
+- `Test_WhatWeDo_WhatWeExpect`
+- `Test_WhatWeDo_WhichConditions_WhatWeExpect`
+
+## Examples from Real Codebase:
+
+- `Test_CreateApiKey_WhenUserIsProjectOwner_ApiKeyCreated`
+- `Test_UpdateProject_WhenUserIsProjectAdmin_ProjectUpdated`
+- `Test_DeleteApiKey_WhenUserIsProjectMember_ReturnsForbidden`
+- `Test_GetProjectAuditLogs_WithDifferentUserRoles_EnforcesPermissionsCorrectly`
+- `Test_ProjectLifecycleE2E_CompletesSuccessfully`
+
+## Testing Philosophy
+
+**Prefer Controllers Over Unit Tests:**
+
+- Test through HTTP endpoints via controllers whenever possible
+- Avoid testing repositories, services in isolation - test via API instead
+- Only use unit tests for complex model logic when no API exists
+- Name test files `controller_test.go` or `service_test.go`, not `integration_test.go`
+
+**Extract Common Logic to Testing Utilities:**
+
+- Create `testing.go` or `testing/testing.go` files for shared test utilities
+- Extract router creation, user setup, models creation helpers (in API, not just structs creation)
+- Reuse common patterns across different test files
+
+**Refactor Existing Tests:**
+
+- When working with existing tests, always look for opportunities to refactor and improve
+- Extract repetitive setup code to common utilities
+- Simplify complex tests by breaking them into smaller, focused tests
+- Replace inline test data creation with reusable helper functions
+- Consolidate similar test patterns across different test files
+- Make tests more readable and maintainable for other developers
+
+## Testing Utilities Structure
+
+**Create `testing.go` or `testing/testing.go` files with common utilities:**
+
+```go
+package projects_testing
+
+// CreateTestRouter creates unified router for all controllers
+func CreateTestRouter(controllers ...ControllerInterface) *gin.Engine {
+	gin.SetMode(gin.TestMode)
+	router := gin.New()
+	v1 := router.Group("/api/v1")
+	protected := v1.Group("").Use(users_middleware.AuthMiddleware(users_services.GetUserService()))
+
+	for _, controller := range controllers {
+		if routerGroup, ok := protected.(*gin.RouterGroup); ok {
+			controller.RegisterRoutes(routerGroup)
+		}
+	}
+	return router
+}
+
+// CreateTestProjectViaAPI creates project through HTTP API
+func CreateTestProjectViaAPI(name string, owner *users_dto.SignInResponseDTO, router *gin.Engine) (*projects_models.Project, string) {
+	request := projects_dto.CreateProjectRequestDTO{Name: name}
+	w := MakeAPIRequest(router, "POST", "/api/v1/projects", "Bearer "+owner.Token, request)
+	// Handle response...
+	return project, owner.Token

+// AddMemberToProject adds member via API call
+func AddMemberToProject(project *projects_models.Project, member *users_dto.SignInResponseDTO, role users_enums.ProjectRole, ownerToken string, router *gin.Engine) {
+	// Implementation...
+}
+```
+
+## Controller Test Examples
+
+**Permission-based testing:**
+
+```go
+func Test_CreateApiKey_WhenUserIsProjectOwner_ApiKeyCreated(t *testing.T) {
+	router := CreateApiKeyTestRouter(GetProjectController(), GetMembershipController())
+	owner := users_testing.CreateTestUser(users_enums.UserRoleMember)
+	project, _ := projects_testing.CreateTestProjectViaAPI("Test Project", owner, router)
+
+	request := CreateApiKeyRequestDTO{Name: "Test API Key"}
+	var response ApiKey
+	test_utils.MakePostRequestAndUnmarshal(t, router, "/api/v1/projects/api-keys/"+project.ID.String(), "Bearer "+owner.Token, request, http.StatusOK, &response)
+
+	assert.Equal(t, "Test API Key", response.Name)
+	assert.NotEmpty(t, response.Token)
+}
+```
+
+**Cross-project security testing:**
+
+```go
+func Test_UpdateApiKey_WithApiKeyFromDifferentProject_ReturnsBadRequest(t *testing.T) {
+	router := CreateApiKeyTestRouter(GetProjectController(), GetMembershipController())
+	owner1 := users_testing.CreateTestUser(users_enums.UserRoleMember)
+	owner2 := users_testing.CreateTestUser(users_enums.UserRoleMember)
+	project1, _ := projects_testing.CreateTestProjectViaAPI("Project 1", owner1, router)
+	project2, _ := projects_testing.CreateTestProjectViaAPI("Project 2", owner2, router)
+
+	apiKey := CreateTestApiKey("Cross Project Key", project1.ID, owner1.Token, router)
+
+	// Try to update via different project endpoint
+	request := UpdateApiKeyRequestDTO{Name: &"Hacked Key"}
+	resp := test_utils.MakePutRequest(t, router, "/api/v1/projects/api-keys/"+project2.ID.String()+"/"+apiKey.ID.String(), "Bearer "+owner2.Token, request, http.StatusBadRequest)
+
+	assert.Contains(t, string(resp.Body), "API key does not belong to this project")
+}
+```
+
+**E2E lifecycle testing:**
+
+```go
+func Test_ProjectLifecycleE2E_CompletesSuccessfully(t *testing.T) {
+	router := projects_testing.CreateTestRouter(GetProjectController(), GetMembershipController())
+
+	// 1. Create project
+	owner := users_testing.CreateTestUser(users_enums.UserRoleMember)

+
+	// 2. Add member
