+# Device Categories — SecuBox 6-Icon System
+
+SecuBox uses a unified 6-category icon system across all devices and interfaces. This **Hamiltonian path** (AUTH → MESH) represents the security flow from authentication to network mesh.
+
+## The Six Categories
+
+| Index | Icon | Name | Role | Color | Hex |
+|-------|------|------|------|-------|-----|
+| 0 | 🔐 | **AUTH** | Authentication / VPN / Encryption | Rust | `#C04E24` |
+| 1 | 🛡️ | **WALL** | Firewall / nftables / CrowdSec | Amber | `#9A6010` |
+| 2 | ⚙️ | **BOOT** | System / OS / Services | Crimson | `#803018` |
+| 3 | 🧠 | **MIND** | AI / CPU / Processing | Indigo | `#3D35A0` |
+| 4 | 🌳 | **ROOT** | Privileges / Integrity / Trust | Teal | `#0A5840` |
+| 5 | 🌐 | **MESH** | Network / WireGuard / Tailscale | Navy | `#104A88` |
+
+## Hamiltonian Path
+
+The order AUTH → WALL → BOOT → MIND → ROOT → MESH follows the **Hamiltonian path** defined in the SecuBox security charter:
+
+```
+AUTH ─────► WALL ─────► BOOT
+  │                       │
+  │   ┌─────────────────┐ │
+  │   │   SecuBox Core  │ │
+  │   └─────────────────┘ │
+  │                       │
+MESH ◄───── ROOT ◄───── MIND
+```
+
+1. **AUTH** — Entry point: user authenticates
+2. **WALL** — Traffic filtered by firewall rules
+3. **BOOT** — System services respond
+4. **MIND** — AI/processing analyzes request
+5. **ROOT** — Privileges verified, integrity checked
+6. **MESH** — Connected to network mesh
+
+## Device Implementations
+
+### Smart-Strip (SBX-STR-01)
+
+Physical HMI module with 6 RGB LEDs and capacitive touch zones.
+
+| Feature | Description |
+|---------|-------------|
+| LEDs | 6× SK6812-MINI-E (RGB, 5V) |
+| Touch | 6× capacitive pads (AT42QT2120) |
+| Interface | USB-C / I²C |
+| Animations | Sweep, breathing, panic |
+
+**LED Behaviors:**
+- **Solid** — Status OK
+- **Flash** — Error or event
+- **Pulse** — Operation in progress
+- **Sweep** — Hamiltonian animation
+
+See: [Smart-Strip](Smart-Strip)
+
+### Eye Remote (Pi Zero W)
+
+Remote dashboard with HyperPixel 2.1 Round display.
+
+| Category | Display Element |
+|----------|-----------------|
+| AUTH | VPN status indicator |
+| WALL | Firewall activity graph |
+| BOOT | System health gauge |
+| MIND | CPU/AI load meter |
+| ROOT | Integrity status |
+| MESH | Network topology |
+
+See: [Eye-Remote](Eye-Remote)
+
+### C3BOX Dashboard
+
+Web-based dashboard using the 6-category layout.
+
+| Category | Panel Content |
+|----------|--------------|
+| AUTH | Active sessions, certificates |
+| WALL | Firewall rules, blocked IPs |
+| BOOT | Services status, uptime |
+| MIND | AI insights, CPU graphs |
+| ROOT | Audit log, integrity checks |
+| MESH | Peers, bandwidth, latency |
+
+### Console TUI
+
+Terminal-based interface with 6-panel layout.
+
+```
+┌─────────────────────────────────────────────────┐
+│ AUTH │ WALL │ BOOT │ MIND │ ROOT │ MESH │
+├──────┴──────┴──────┴──────┴──────┴──────┤
+│                                         │

+│                                         │
+└─────────────────────────────────────────┘
+```
+
+## Color Palette CSS
+
+```css
+:root {
+  --auth: #C04E24;  /* Rust */
+  --wall: #9A6010;  /* Amber */
+  --boot: #803018;  /* Crimson */
+  --mind: #3D35A0;  /* Indigo */
+  --root: #0A5840;  /* Teal */
+  --mesh: #104A88;  /* Navy */
+}
+```
+
+## HID Mapping (Smart-Strip)
+
+| Pad | HID Usage | Linux Key |
+|-----|-----------|-----------|
+| AUTH | `0x0220` | KEY_F13 |
+| WALL | `0x021F` | KEY_F14 |
+| BOOT | `0x0192` | KEY_F15 |
+| MIND | `0x019C` | KEY_F16 |
+| ROOT | `0x0194` | KEY_F17 |
