Design Documentation Index

1. Purpose

docs/design is the decision layer between formal specs and source contracts. It explains how AIKernel behaves as an AIOS through explicit separation of Kernel, Vfs, and system-call-like interface boundaries.

2. Design Principles

• Kernel: control point for execution-state transitions and fail-closed governance
• Vfs: persistence boundary for intelligence assets
• System-call equivalent: side-effect control through interfaces (tooling/security/provider)
