Architecture

Arcstone evaluates whether a resulting state of the world is admissible before it is allowed to exist.

Arcstone operates upstream of software, AI, optimization, and execution. It defines legitimacy, admissibility, and authorization prior to any action layer.

Core Ordering Principle

Identity → Canon → Legitimacy → Authorization → Implementation

Arcstone first defines what a system is. Then defines what classes of states may exist. Then evaluates specific proposed states. Only then may implementation occur.

Layered Stack

• Identity & Continuity Layer
  Defines long-horizon survivability, reversibility, and continuity constraints.
• Canon & Definition Layer
  Establishes formal meanings, categories, and invariants.
• Legitimacy & Governance Layer
  Determines whether a class of state is allowed to exist at all.
• Authorization & Admissibility Layer
  Evaluates specific proposed states against legality, safety, and impact bounds.
• Existence-Governance Layer
  Enforces existence-level permissioning before execution layers are reachable.
• Implementation Layer (Downstream)
  Software, automation, and tooling derived from upstream governance.

State Evaluation Orientation

Arcstone does not ask:

“Can this be built?”

Arcstone asks:

“May this state exist?”
“May this affect humans?”
“May this persist over time?”

Deterministic Resolution

Every proposed state resolves to exactly one outcome:

• PASS — State may exist
• PWC — State may exist under constraints
• FREEZE — State indeterminate / suspended
• FAIL — State illegal

Execution Relationship

Execution is downstream of authorization.

Optimization is downstream of legitimacy.

If legitimacy cannot be established, correct behavior is inactivity.

What Arcstone Is Not

• Not a product
• Not a platform
• Not an AI system
• Not a marketplace
• Not an application suite

Arcstone is a governing substrate.

Design Posture

• Fail-closed
• Refusal-first
• Deterministic
• Non-promissory
• Long-horizon

Arcstone is architecture for civilizations that intend to survive intelligence, scale, and time.
