Implements nested isolation layers (Network → Firewall → Container → VM → Trusted) with each layer assigned a security color that enforces data flow constraints. ``` ┌─────────────────────────────────────────────────────────────────────────────┐ │ COLORED OPERAD ISOLATION STACK │ └─────────────────────────────────────────────────────────────────────────────┘ External World (Untrusted) │ ▼ ┌──────────────────────────────────────────────────────────────────────┐ │ 🔴 RED: Network Boundary (trit=-1) │ │ • Network namespace isolation │ │ • DNS filtering (*.signal.org only) │ │ • Firewall: outbound-only, ports 443/80 │ │ ┌────────────────────────────────────────────────────────────────┐ │ │ │ 🟡 YELLOW: Container Boundary (trit=-1) │ │ │ │ • Podman/Docker rootless │ │ │ │ • --privileged=false, --read-only │ │ │ │ • Seccomp profile, AppArmor/SELinux │ │ │ │ • CAP_DROP=ALL, CAP_ADD=NET_RAW │ │ │ │ ┌──────────────────────────────────────────────────────────┐ │ │ │ │ │ 🟢 GREEN: VM Boundary (trit=0) │ │ │ │ │ │ • Firecracker microVM │ │ │ │ │ │ • 1 vCPU, 512MB RAM │ │ │ │ │ │ • Minimal kernel, read-only rootfs │ │ │ │ │ │ ┌────────────────────────────────────────────────────┐ │ │ │ │ │ │ │ 🔵 BLUE: Trusted Core (trit=+1) │ │ │ │ │ │ │ │ • Signal CLI process │ │ │ │ │ │ │ │ • Key material in memory-encrypted enclave │ │ │ │ │ │ │ │ • Attestation verification │ │ │ │ │ │ │ └────────────────────────────────────────────────────┘ │ │ │ │ │ └──────────────────────────────────────────────────────────┘ │ │ │ └────────────────────────────────────────────────────────────────┘ │ └──────────────────────────────────────────────────────────────────────┘ ``` ## GF(3) Conservation ``` RED(-1) ⊗ YELLOW(-1) ⊗ GREEN(0) ⊗ BLUE(+1) = -1 To balance: Add dynamic-sufficiency(-1) + skill-dispatch(0) + signal-messaging(+1) Full triad: (-1) + (-1) + (0) + (+1) + (-1) + (0) + (+1) = -1 + 1 = 0 ✓ ``` | Role | Skill/Layer | Trit | Function | |------|-------------|------|----------| | **MINUS** (-1) | signal-isolated-auth | -1 | **THIS SKILL** - validates enclosure | | **MINUS** (-1) | Network + Container | -2 | External constraints | | **ERGODIC** (0) | VM boundary | 0 | Coordination layer | | **PLUS** (+1) | Trusted core | +1 | Key generation | ## Supported Signal Clients | Client | Technology | Status | Notes | |--------|------------|--------|-------| | **signal-cli** | Java | ✅ Primary | Full protocol support | | **presage** | Rust | ✅ Supported | Modern, performant | | **whisperfish** | Rust/QML | ⚠️ Experimental | Sailfish OS focused | | **libsignal** | Rust | ⚠️ Library | Requires wrapper | ## Security Color Rules ### Color Flow Constraint Data can only flow **INWARD** (less trusted → more trusted): ``` RED → YELLOW → GREEN → BLUE ✓ BLUE → RED ✗ (security violation) ``` ### Color-to-Trit Mapping | Color | Trust Level | Trit | Meaning | |-------|-------------|------|---------| | 🔴 RED | 1 (lowest) | -1 | External constraint | | 🟡 YELLOW | 2 | -1 | Container constraint | | 🟢 GREEN | 3 | 0 | Boundary coordination | | 🔵 BLUE | 4 (highest) | +1 | Trusted generation | ## Usage ### Python API ```python from signal_isolation_manager import ( SignalIsolationManager, SignalClientType, build_agentorama_signal_pathway, ) # Build maximally isolated pathway pathway = build_agentorama_signal_pathway( name="agent-signal-secure", client_type=SignalClientType.SIGNAL_CLI, max_isolation=True, # VM + Container ) # Start isolated environment manager = pathway.isolation_manager await manager.start_isolated() # Authenticate via device linking link_uri = await manager.authenticate_link("agent-o-rama") print(f"Scan QR code: {link_uri}") # Or register new account await manager.authenticate_register("+1234567890") await manager.verify_code("123456") # Get s-expression for categorical processing print(manager.get_enclosure_sexp()) ``` ### Julia API (WorldColoredOperads) ```julia using Gay.WorldColoredOperads # Build Signal-specific enclosure enclosure = world_signal_enclosure(:signal_cli;
