Modules

Modules are major structural components of Arcstone OS.

They describe functional partitions within the architecture, not products or deployable packages.

Core Modules

• Existence-Governance Module
  Enforces existence-level permissioning.
• Authorization Module
  Evaluates admissibility of proposed states.
• Legitimacy Module
  Determines lawful classes of state.
• Continuity Module
  Preserves long-horizon coherence.
• Identity Module
  Maintains persistent entity representation.
• Memory Module
  Supports structured recall across time.

Evaluation Modules

• State Evaluation Engine
  Computes deterministic outcomes.
• Constraint Resolution Engine
  Applies bounds and restrictions.

Interface Modules

• Human Interface Layer
  Human-facing surfaces.
• Machine Interface Layer
  Machine-facing surfaces.

Module Relationships

Modules are arranged hierarchically.

Upstream modules constrain downstream modules.

Downstream modules never override upstream constraints.

What Modules Are Not

• Not microservices
• Not plugins
• Not feature bundles
• Not products

Modules exist to preserve structural clarity.

Detailed module specifications appear in the Library.
