THE GUARDIAN LAYER

Privacy and Security Guardrails

VOXEL operates as an isolated desktop companion. The AI Brain is strictly decoupled from direct operating system execution through hardware-level sandboxing, input validation, and immutable permission boundaries.

Access Control
Sandboxed
ENFORCED
Least-Privilege Execution
Bound: Low to Critical Tiering

The AI agent runs in an isolated user-space sandbox. System commands require explicit clearance and cannot elevate privileges or modify host policies.

Privilege FloorUser-space (No Sudo)
Subsystem ProtocolOS Sandboxing
Execution Gate
Sandboxed
ACTIVE
Immutable Tool Allowlist
Bound: Kernel Filter

Only pre-vetted, deterministically compiled tool adapters can run. Arbitrary terminal execution and unbounded script spawning are rejected at the kernel boundary.

Allowed Handlers18 Verified Tools
Subsystem ProtocolDeterministic RPC
Input Verification
Sandboxed
ACTIVE
Prompt-Injection Immunity
Bound: Heuristic Isolation

Multilayer heuristic parsing inspects inbound text and speech payloads. System prompts and safety guardrails cannot be overridden by conversational adversarial injection.

Validation Latency< 3.2ms Local
Subsystem ProtocolDual-Pass AST
Data Sovereignty
Sandboxed
PROTECTED
Local Encrypted Memory
Bound: Zero Cloud Leaks

Structured persistent recall stays on-device in an encrypted SQLite database. Zero microphone audio or vector embeddings leave your hardware without your explicit consent.

Cipher StandardAES-256-GCM / SQLCipher
Subsystem ProtocolHardware Isolated

Hardware Kill-Switch and Emergency STOP

Zero-Delay

The AI assistant cannot modify its own security layers. An unblockable hardware stop breaks all tool pipelines immediately.
