# Inveetaire — Production Readiness Audit Walkthrough

## Verification

**`php -l` result:** All 15 modified files passed — no syntax errors.

---

## Part 1 — PHP 7.4 Compatibility (12 files fixed)

### `str_starts_with()` → `strpos() === 0`

| File | Line(s) | Before | After |
|---|---|---|---|
| `app/services/MediaService.php` | 113 | `str_starts_with($mime, 'image/')` | `strncmp($mime, 'image/', 6) === 0` |
| `app/modules/Media/MediaController.php` | 221, 285 | `str_starts_with($path, $code.'/')` | `strpos($path, $code.'/') !== 0` |
| `app/modules/Messaging/MessageDeliveryService.php` | 30 | `str_starts_with($cleaned, '0')` | `strpos($cleaned, '0') === 0` |
| `app/modules/Developer/DdlGeneratorService.php` | 227–242, 284, 287 | `str_starts_with()` × 8 | `strpos() === 0` × 8 |
| `app/modules/Developer/SynchronizationService.php` | 390 | `str_starts_with(ltrim($s), '--')` | `strpos(ltrim($s), '--') !== 0` |

### `str_contains()` → `strpos() !== false`

| File | Line(s) | Replaced |
|---|---|---|
| `app/modules/Messaging/MessageTemplateService.php` | 59, 60 | `str_contains()` × 4 |
| `app/modules/Developer/LogManagerService.php` | 255, 257 | `str_contains()` × 2 |

### `\GDImage` class → `is_resource()`

| File | Line | Change |
|---|---|---|
| `app/services/ImageProcessor.php` | 105 | `instanceof \GDImage` removed — on PHP 7.4, GD handles are resources, not objects |

### `match` expressions → `if/elseif/else`

| File | Line |
|---|---|
| `app/views/auth/login.php` | 53 |
| `app/views/auth/forgot_password.php` | 58 |
| `app/views/auth/reset_password.php` | 62 |
| `app/views/invitation/dashboard.php` | 114 |

> **Arrow functions (`fn()`)** in `SchemaReaderService.php` and `SyncLogService.php` were reviewed and confirmed **PHP 7.4 compatible** — no changes required.

## Part 2 — Composer

No `composer.json` found. Project uses a custom PSR-4 autoloader (`app/core/Autoloader.php`).
**No action required.**

---

## Part 3 — Security Hardening (2 files)

### `reset_dev_db.php` and `verify_db_reset.php`

Both scripts now contain a PHP-level production guard at the very top:

```php
(function () {
    // Reads APP_ENV and DEVELOPER_MODE from .env manually
    // Halts with HTTP 403 if not (APP_ENV=local AND DEVELOPER_MODE=true)
})();
```

**Guard behavior:**
- If `.env` is unreadable → treats env as `production` → blocks (safe default)
- If `APP_ENV != local` → blocks
- If `DEVELOPER_MODE != true` → blocks
- Only passes if both conditions are satisfied simultaneously

This is defense-in-depth — Apache rewrite already prevents access in most cases, but this ensures PHP-level protection regardless of web server configuration.

---

## Part 4 — Configuration Fixes

### `config/app.php` — `developer_mode` default

```diff
- 'developer_mode' => filter_var($_ENV['DEVELOPER_MODE'] ?? true, FILTER_VALIDATE_BOOLEAN),
+ 'developer_mode' => filter_var($_ENV['DEVELOPER_MODE'] ?? false, FILTER_VALIDATE_BOOLEAN),
```

When `DEVELOPER_MODE` is absent from `.env` (as on a freshly deployed server), developer mode now defaults to **off**. Developers must explicitly set `DEVELOPER_MODE=true` in their local `.env`.

### `.env.example` — Missing `STORAGE_MEDIA_BASE` key added

```ini
# Root directory for couple media (slots: hero, gallery, music_file, etc.).
STORAGE_MEDIA_BASE=/path/to/inveetaire/storage/uploads/couples
```

---

## Part 5–9 — No Action Required

| Part | Status | Notes |
|---|---|---|
| Composer dependencies | ✅ N/A | No Composer — custom autoloader |
| File upload portability | ✅ Already portable | `DIRECTORY_SEPARATOR` + `dirname(__DIR__)` fallbacks |
| Apache routing | ✅ Correct | Both `.htaccess` files well-formed |
| Session cookie security | ✅ Correct | `secure` auto-set to `true` when `APP_ENV=production` |
| Hardcoded URLs | ✅ Documented | `.env` local paths expected; `.env.example` has portable docs |

## Deployment Checklist (for production)

Before going live, set these in your production `.env`:

```ini
APP_ENV=production
APP_DEBUG=false
DEVELOPER_MODE=false
APP_URL=https://your-production-domain.com

STORAGE_UPLOADS=/absolute/path/to/storage/uploads
STORAGE_EXPORTS=/absolute/path/to/storage/exports
STORAGE_REPORTS=/absolute/path/to/storage/reports
STORAGE_CACHE=/absolute/path/to/storage/cache
STORAGE_LOGS=/absolute/path/to/storage/logs
STORAGE_SESSIONS=/absolute/path/to/storage/sessions
STORAGE_MEDIA_BASE=/absolute/path/to/storage/uploads/couples
```

And verify:
- All `storage/` subdirectories exist and are writable by the web server
- `storage/` is NOT web-accessible (confirmed by `.htaccess`)
- PHP 7.4 is the active runtime on the server
- `php.ini` has `fileinfo` extension enabled (required by `MediaService::detectMime()`)
- `php.ini` has `gd` extension enabled (required by `ImageProcessor`)
- `php.ini` has `exif` extension enabled (required for JPEG auto-orientation)
