Zero-Trust Execution Architecture

Terminal Execution Firewall & Sandbox Security

Pak-LLM Coder isolates all autonomous agent actions behind an immutable Human-in-the-Loop (HITL) gate and real-time command parser. The Terminal Execution Firewall prevents destructive shell commands, network egress leaks, and unauthorized file overwrites.

Blocked Destructive Commands

Commands attempting recursive disk erasure (rm -rf /), direct system file alterations, raw partition formatting, or obfuscated payloads are intercepted and denied before execution.

Human-in-the-Loop (HITL) Gate

Every multi-step file repair, package installation, or shell execution requires explicit user authorization via interactive approval cards or terminal confirmation prompts.

Browser & WASM Sandbox Guarantees

  • •Isolated In-Memory Filesystems: Pyodide and WebContainers run inside isolated V8 workers with ephemeral virtual disks that cannot access host memory or local storage.
  • •Restricted Network Egress: Code sandboxes enforce Content Security Policy (CSP) headers blocking cross-origin data exfiltration.
  • •Cryptographic Integrity: Pre-built CLI installers and binaries are sealed with detached PGP/Minisign signatures and SHA-256 digests.
