🎯 Issue #137 - Permission Management CRUD API

Part of RBAC Phase 4 Epic (#108)

📋 Summary

Implements complete CRUD API for system-wide permission management, enabling admins to create, read, update, and delete permissions with strict validation and safety checks.

✨ Features

5 RESTful Endpoints:

  • GET /v1/permissions - List all permissions grouped by resource
  • POST /v1/permissions - Create permission with resource.action validation
  • GET /v1/permissions/{id} - Get details with assigned roles
  • PATCH /v1/permissions/{id} - Update description (name immutable for safety)
  • DELETE /v1/permissions/{id} - Delete permission (blocked if assigned to roles)

Key Design Decisions:

  • ✅ Permission names are immutable after creation (security best practice)
  • ✅ Deletion blocked when permission assigned to roles (referential integrity)
  • ✅ Strict resource.action naming convention enforced via regex
  • Admin-only access via PermissionManagementPolicy
  • ✅ Extended Spatie Permission model with description field

🏗️ Implementation

New Files:

  • PermissionManagementController.php (153 lines) - 5 RESTful methods
  • CreatePermissionRequest.php (56 lines) - Validation with regex
  • UpdatePermissionRequest.php (49 lines) - Description-only updates
  • PermissionManagementPolicy.php (55 lines) - Admin authorization
  • Permission.php (34 lines) - Extended Spatie model
  • PermissionManagementApiTest.php (344 lines) - 24 tests, 109 assertions
  • Migration (34 lines) - Add description column

Modified Files:

  • routes/api.php - Added 5 routes under auth:sanctum
  • config/permission.php - Configured custom Permission model
  • AppServiceProvider.php - Registered policy
  • CHANGELOG.md - Documented changes

✅ Quality Gates

  • PHPStan Level Max: ✅ No errors
  • Laravel Pint: ✅ Code style compliant (PSR-12)
  • Tests: ✅ 257 passed (814 assertions) - 24 new tests
  • REUSE 3.3: ✅ All files have SPDX headers
  • TDD: ✅ Tests written first, implementation followed

📊 Test Coverage

24 comprehensive tests covering:

  • ✅ Authentication (401)
  • ✅ Authorization (403)
  • ✅ Validation (422)
  • ✅ Not Found (404)
  • ✅ Success scenarios (200, 201, 204)
  • ✅ Edge cases: Deletion blocking, name format validation, immutability

🔗 Dependencies

⚠️ Large PR Justification

752 lines (exceeds 600 line limit)

Reason: Atomic TDD implementation

  • 344 lines = comprehensive test suite (cannot split without breaking TDD)
  • 153 lines = controller with 5 methods (RESTful unit)
  • Remaining = form requests, policy, migration, model (cohesive feature)

Splitting would violate:

  • ❌ TDD Mandatory principle (tests must come with implementation)
  • ❌ Feature atomicity (permission CRUD is indivisible)

📝 Checklist

Closes #137

- Add 5 RESTful endpoints for permission management
  - GET /v1/permissions - List all permissions grouped by resource
  - POST /v1/permissions - Create permission with resource.action validation
  - GET /v1/permissions/{id} - Get details with assigned roles
  - PATCH /v1/permissions/{id} - Update description (name immutable)
  - DELETE /v1/permissions/{id} - Delete (blocked if assigned to roles)

- Extend Spatie Permission model with description field
  - New migration: add description column to permissions table
  - Custom App\Models\Permission with description support
  - Configure custom model in config/permission.php

- Implement authorization via PermissionManagementPolicy
  - Admin-only access (permissions.read/create/update/delete)
  - Consistent with RoleManagementPolicy pattern

- Add form request validation
  - CreatePermissionRequest: strict resource.action regex, max 255 chars
  - UpdatePermissionRequest: description-only updates, name prohibited

- Add comprehensive test coverage
  - 24 tests covering all endpoints and edge cases
  - 109 assertions for authorization, validation, and business logic
  - Tests for deletion blocking when assigned to roles

Quality gates passed:
- PHPStan Level Max: ✅ No errors
- Laravel Pint: ✅ Code style compliant
- Tests: ✅ 257 passed (814 assertions)
- REUSE: ✅ All files have SPDX headers

File Description
tests/Feature/PermissionManagementApiTest.php Comprehensive test suite with 24 tests covering all CRUD operations and edge cases
routes/api.php Added 5 new permission management routes under auth:sanctum middleware
database/migrations/2025_11_12_193139_add_description_to_permissions_table.php Migration adding nullable description column to permissions table
config/permission.php Updated to use custom App\Models\Permission instead of Spatie's model
app/Providers/AppServiceProvider.php Registered PermissionManagementPolicy for Permission model
app/Policies/PermissionManagementPolicy.php New policy enforcing permissions-based authorization for all operations
app/Models/Permission.php Extended Spatie Permission model with description field support
app/Http/Requests/Api/V1/UpdatePermissionRequest.php Validation for updates - description only, name prohibited for security
app/Http/Requests/Api/V1/CreatePermissionRequest.php Validation for creation with strict resource.action format enforcement
app/Http/Controllers/Api/V1/PermissionManagementController.php Controller implementing 5 CRUD methods with authorization and safety checks
CHANGELOG.md Documented new permission management API feature

- Change Permission model to use casts() method (project convention)
- Fix AppServiceProvider to import App\Models\Permission (was using Spatie)
- Fix tests to import App\Models\Permission (was using Spatie)
- Use assertJsonCount instead of closure for better readability

Note: Copilot suggested nullsafe operators for timestamps, but PHPStan
correctly identified them as unnecessary (created_at/updated_at never null).
RoleManagementController has same pattern but predates strict PHPStan rules.

Pull Request Overview

Copilot reviewed 11 out of 11 changed files in this pull request and generated 1 comment.

Found through systematic grep search after initial review fixes.

CRITICAL SECURITY ISSUES FIXED:
- PermissionManagementPolicy: Used wrong model class (authorization bypass risk)
- CreateRoleRequest/UpdateRoleRequest: Wrong validation model
- RolesAndPermissionsSeeder: Created Spatie models instead of custom
- PersonApiTest/RoleApiTest/RoleManagementApiTest: Used wrong model in tests

All files now correctly import App\Models\Permission instead of
Spatie\Permission\Models\Permission.

Root cause: Pattern-based copying without systematic verification after
creating custom Permission model. Should have run:
  grep -r 'Spatie\\Permission\\Models\\Permission' .

Affected files (7):
- app/Policies/PermissionManagementPolicy.php
- app/Http/Requests/Api/V1/CreateRoleRequest.php
- app/Http/Requests/Api/V1/UpdateRoleRequest.php
- database/seeders/RolesAndPermissionsSeeder.php
- tests/Feature/PersonApiTest.php
- tests/Feature/RoleApiTest.php
- tests/Feature/RoleManagementApiTest.php
Copilot review identified missing $fillable property for description field.

While Spatie Permission has $guarded = [], explicitly declaring fillable
fields is Laravel best practice for:
- Security: Prevent accidental mass assignment of future fields
- Documentation: Clear intent of which fields are expected
- Maintainability: Easier to understand model interface

Fixes Copilot review comment #9.
Tests: All 24 Permission Management tests pass.
