### 2. Developer Console Module

#### New Files

| File | Description |
|------|-------------|
| `app/modules/Developer/DeveloperController.php` | 3 route handlers: index, database, schema |
| `app/modules/Developer/DeveloperService.php` | MySQL info queries + documentation status checker |
| `app/views/layouts/developer.php` | Dark terminal-style layout with sidebar nav |
| `app/views/developer/console.php` | Landing dashboard with feature cards |
| `app/views/developer/database.php` | MySQL connection info + Supabase DX002 placeholders |
| `app/views/developer/schema.php` | Schema doc file status with coverage progress |
| `routes/developer.php` | Route definitions for `/app/developer` |

#### Modified Files

| File | Change |
|------|--------|
| `app/core/Router.php` | Added `'developer'` to the `$files` route loading list |
| `app/views/layouts/admin.php` | Added "Dev Console" link to admin sidebar footer |

---

### 3. Routes Available

| Method | URL | Handler |
|--------|-----|---------|
| GET | `/app/developer` | `DeveloperController@index` |
| GET | `/app/developer/database` | `DeveloperController@database` |
| GET | `/app/developer/schema` | `DeveloperController@schema` |

**Access control:** `AuthMiddleware + RoleMiddleware (super_admin)`

## Developer Console Design

The Developer Console uses a **dark terminal aesthetic** intentionally distinct from the Admin Portal:

- **Color scheme:** GitHub-dark-inspired (`#0d1117` background, `#58a6ff` blue accent, `#3fb950` green)
- **Typography:** JetBrains Mono (monospace) for all code, metrics, and labels; Inter for prose
- **Breadcrumb path:** Shows `/developer/{page}` in terminal path style
- **Coming Soon items:** DX002 (Sync) and DX003 (Health, Logs, Queue) shown greyed-out with sprint badges
- **No edits to Admin Portal layout** (other than adding the console link)

---

## Documentation Rules Established

Every future schema change MUST update:
1. `README_SCHEMA.md` (if modules/tables change)
2. `RELATIONSHIP.md` (if relationships change)
3. `tables/{table}.md` (for affected tables)
4. `CHANGELOG.md` (always, with version bump)
5. `AI_CONTEXT.md` (if business logic changes)
6. `docs/database/schema.sql` (keep in sync with `database/schema.sql`)
