Subject: [PATCH 1/5] fix: resolve parallel test execution failures (Issue #62)

Implemented process-specific KEK files to eliminate race conditions
in parallel test execution.

Root cause:
- All tests shared the same KEK file (storage/app/keys/kek.key)
- Parallel processes overwrote each other's KEK files
- Led to 'Failed to unwrap idx_key' errors (~1-10% failure rate)

Solution:
- Added TenantKey::setKekPath() to support custom KEK paths
- Modified getKekPath() to use static $kekPath property when set
- Updated TenantKeyTest and PersonTest to use process-specific paths:
  storage/app/keys/kek-test-{pid}.key
- Added cleanup in afterEach hooks

Testing:
- Verified 10 consecutive successful parallel test runs (79/79 pass)
- Tests run in 7-8s with 2 parallel processes
- PHPStan Level 9: Clean
- Pint PSR-12: Compliant

Fixes #62

Subject: [PATCH 2/5] refactor: remove redundant directory creation in
 PersonTest

TenantKey::generateKek() already handles directory creation,
so the manual mkdir in PersonTest.php beforeEach is unnecessary.
This simplifies the code and reduces duplication.

Addresses Copilot review comment on PR #63.

Subject: [PATCH 3/5] feat: PR-5 - Person API endpoints with auth and
 permissions (Issue #50)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements JSON API endpoints for Person resource with full auth/authz.

## Core Implementation

**PersonController** (93 LOC):
- POST /api/v1/tenants/{tenant}/persons - Create/update Person
- GET /api/v1/tenants/{tenant}/persons/by-email - Search by email
- Uses PersonRepository for business logic
- Returns sanitized JSON (no _enc/_idx exposure)

**StorePersonRequest** (58 LOC):
- Validates email_plain (required, email format)
- phone_plain and note_enc are optional
- Custom error messages

**Routes** (routes/api.php):
- Nested under auth:sanctum middleware
- SetTenant middleware for tenant context
- Spatie Permission middleware (person.write, person.read)

## Middleware Setup

**bootstrap/app.php**:
- Registered 'permission' and 'role' middleware aliases
- Required for Spatie Permission integration

**User Model**:
- Added HasRoles trait from Spatie Permission
- Enables permission assignment in tests

## Testing

**PersonApiTest** (288 LOC, 16 tests):
- ✅ Authentication (401 when not authenticated)
- ✅ Authorization (403 without permissions)
- ✅ Validation (422 for invalid data)
- ✅ Success cases (201 create, 200 search)
- ✅ Tenant isolation (404 for wrong tenant)
- ✅ Security (no _enc/_idx in responses)
- ✅ Case-insensitive search
- All 95 tests passing (237 assertions)

## Database Changes

**Migration update**:
- Made phone_enc and phone_idx nullable
- Allows creating Person with only email

## Quality Gates

- ✅ **Tests**: 95 passed, 237 assertions
- ✅ **PHPStan**: Level 9, 0 errors
- ✅ **Pint**: PSR-12 compliant
- ✅ **LOC**: ~439 new lines (under 600 limit)
- ✅ **Parallel tests**: Working perfectly

## API Examples

**Create Person:**
```bash
POST /api/v1/tenants/1/persons
Authorization: Bearer {token}
{
  "email_plain": "user@example.com",
  "phone_plain": "+49 123 456789",
  "note_enc": "Optional note"
}
# Returns: {"id": 1, "tenant_id": 1, "created_at": "...", "updated_at": "..."}
```

**Search by Email:**
```bash
GET /api/v1/tenants/1/persons/by-email?email=user@example.com
Authorization: Bearer {token}
# Returns: {"id": 1, "tenant_id": 1, "created_at": "...", "updated_at": "..."}
```

## Related

- Issue #50 (PR-5: API Endpoints)
- Follows: PR-4 (Sanctum Auth), PR-3 (SetTenant Middleware)
- Prepares for: PR-6 (Rotation & Maintenance)

## Notes

- Permissions are team-scoped (tenant_id) via Spatie configuration
- Encrypted fields and blind indexes never exposed in responses
- Search is case-insensitive (normalized at blind index level)
- Phone is optional (can create Person with email only)

From 023e5d6ff133d72d5bd356048b4fb8d35657748d Mon Sep 17 00:00:00 2001
From: Holger Schmermbeck <holger@secpal.app>

Subject: [PATCH 4/5] refactor: Apply DRY principles - centralize helpers and
 use API Resources
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses Copilot PR review comments for Issue #50 PR-5.

## DRY Violations Fixed

**1. KEK Path Construction (3x duplication):**
- Centralized getTestKekPath() in tests/Pest.php
- Removed duplicate functions from PersonTest, TenantKeyTest, PersonApiTest
- Added cleanupTestKekFile() helper for consistent cleanup

**2. Permission Assignment (middleware duplication):**
- Moved givePermissionWithTenant() to tests/Pest.php
- Used across PersonApiTest for proper Spatie Permission team context
- Single source of truth for tenant-scoped permission logic

**3. API Response Structure (2x duplication in Controller):**
- Created PersonResource following Laravel best practices
- Replaced manual JSON assembly in store() and byEmail()
- Disabled resource wrapping with $wrap = null for clean responses
- Consistent response format across all Person endpoints

## Changes

**New:**
- app/Http/Resources/PersonResource.php (45 LOC)

**Modified:**
- tests/Pest.php (+33 LOC) - Added 3 global test helpers
- app/Http/Controllers/PersonController.php (-6 LOC) - Uses PersonResource
- tests/Feature/PersonApiTest.php (-13 LOC) - Uses central helpers
- tests/Feature/PersonTest.php (-5 LOC) - Uses getTestKekPath()
- tests/Feature/TenantKeyTest.php (-10 LOC) - Uses cleanupTestKekFile()

## Benefits

- ✅ Single source of truth for test KEK paths
- ✅ Consistent permission assignment across tests
- ✅ Laravel Resource pattern for API responses
- ✅ ~44 LOC reduction through refactoring
- ✅ Easier maintenance and updates

## Quality

- ✅ Tests: 95 passed (237 assertions)
- ✅ PHPStan: Level 9, 0 errors
- ✅ Pint: PSR-12 compliant

Subject: [PATCH 5/5] fix: Remove redundant setPermissionsTeamId call in
 PersonApiTest

Addresses Copilot review comment on PR #64.

The manual setPermissionsTeamId() call on line 60 was redundant since
givePermissionWithTenant() helper already handles setting and resetting
the team ID context.

This eliminates duplication and makes the code cleaner.
