ADR 002: Zero Subprocesses Policy

This section details the specifications and guidelines for ADR 002: Zero Subprocesses Policy within the Zenzic ecosystem.

Context

Running arbitrary executables or scripts via subprocesses (e.g., os.system, subprocess) introduces severe security, portability, and determinism risks into the Core execution environment.

Decision

Absolute prohibition of os.system and subprocess within the Core.

Rationale

To guarantee a deterministic, safe, and portable execution environment, all logic must run strictly within the Python runtime. This adheres to the strict requirement of zero subprocesses.

Invariants

  • Zero subprocesses invoked by the Core.
  • Complete reliance on pure Python runtime.

Consequences

  • No dependency on external binary tools or OS scripts.
  • Improved security boundary and testability.
