+# LandveX Platform Architecture v2.0
+
+## One Platform, Multiple Roles
+
+**LandveX is one platform — not two.**
+
+Same backend, same database, same API, same map.
+Only the modules and detail level differ by role.
+
+```
+LandveX Platform
+├── Customer Portal
+│   ├── Dashboard
+│   ├── Map
+│   ├── Decision Cases
+│   ├── Reports
+│   └── Administration
+│
+├── Operations Console
+│   ├── Live Missions
+│   ├── Coverage
+│   ├── Hotspots
+│   ├── Mission Generator

+
+## Same Artifact Viewer Everywhere
+
+**Same Artifact, different detail level by role:**
+
+| Role | Sees |
+|------|------|
+| Customer | Image, Date, Recommendation |
+| Operations | + Hash, Metadata, EXIF, GPS |
+| Intelligence Lab | + AI results, Bounding boxes, Replay, Model version, Lineage |
+
+## Same Map Everywhere
+
+**Same map, different layers by role:**
+
+| Role | Layers |
+|------|--------|
+| Customer | Decision Cases, Risk, Objects, History |
+| Operations | + Zoomers, Uploads, Coverage, Hotspots, Knowledge Gaps, Contradictions |
+| Intelligence Lab | + Bounding boxes, Segmentation, AI confidence, Replay, Dataset status, Annotations |
+
+## Role-Based Access
+
+| User | Modules |
+|------|---------|
+| **Erik** | Everything: Operations, Intelligence Lab, Admin, Economy, Customers, Missions, Decision Cases |
+| **Johan** | Operations, Intelligence Lab, Replay, Models, Logs, Deploy, Health |
+| **Pilot Customer** | Dashboard, Map, My Missions, Reports, Decisions |
+| **Municipality** | My Area, My Objects, My Decision Cases, My Reports, History |
+
+## Developer Mode
+
+Intelligence Lab is not a separate product.
+It is **Developer Mode** in the same platform.
+

+
+**Reused across all roles:**
+- Authentication
+- Map engine
+- API
+- Permissions
+- Design system
+- Component library
+- Logging
+
+## Architecture Principle
+
+> **One platform. One API. One data model. One map. One Artifact system. Multiple roles.**
+
+This means Intelligence Lab is not a separate system, but an **advanced work mode** in the same platform customers use. You reuse everything — from authentication and map engine to Artifact Viewer and Decision Cases — and only differentiate on **which information and tools each role gets access to**.
+
+## Benefits
+
+- Lower development cost
+- Easier maintenance
+- Consistent user experience
+- Faster iteration
+- No "rebuild Intelligence Lab" moments
+
+## Current Status
+
+- ✅ Domain model supports all roles
+- ✅ API layer ready
+- ⏳ Role-based access control (RBAC)
+- ⏳ Module system
+- ⏳ Developer Mode toggle
