UCA Formal Specification v0.1.0

Preamble

This document is the formal specification of the Universal Constitutional Adapter (UCA) — Layer 6.1 of the ICore ecosystem. UCA is the last constitutional layer: everything beyond UCA is external, never part of the constitution itself.

UCA does not implement anything constitutionally new. UCA is the boundary condition that makes sovereignty possible in a world of external systems. Without UCA, the constitution is isolated. With UCA, the constitution is sovereign everywhere.

2.2 Boundary Properties

2.3 What Crosses the Boundary

Section 3: The Adapter Contract Model

3.1 Adapter Definition

3.2 Adapter Structure

Every adapter must declare:

3.3 Adapter Invariants

Section 4: Adapter Domains

4.1 The Five Domains

4.2 Domain Sufficiency

Every interaction between a constitutional system and the external world falls into exactly one of these five categories:

• Naming: "How do external systems refer to this constitutional entity?"
• Serialization: "How do I serialize this constitutional data for external consumption?"
• Execution: "Where does this constitutional code actually run?"
• Storage: "Where does this constitutional state actually persist?"
• Communication: "How does this constitutional message actually reach its destination?"

Section 6: The Extension Protocol

6.1 How New Adapters Are Added

Adding a new adapter is an Extension amendment — the fast-track pipeline in Part IV:

6.2 How Adapters Are Removed

Removing an adapter is a Removal amendment:

6.3 Adapter Upgrade Path

Adapters evolve freely as long as they maintain their contract:

Section 7: The Sovereignty Guarantee

7.1 Formal Sovereignty

The sovereignty guarantee is the constitutional promise that UCA enforces:

For all operations O, all external systems E, and all constitutional components C:

C may use E through UCA. E may never alter C.

C may remove E through UCA at any time. E may never prevent C from doing so.

C may be fully verified without E. E may never be required for C's verification.

7.2 Sovereignty Tests

7.3 The D4 Rule Formalized

D4 ("Adaptation is the boundary") is the constitutional rule that UCA operationalizes:

∀ layer L ∈ {USCP, USC, UCE, UCC, UCM, UCL, UCRS, UCModels, URS, UVS, USR}:
    L depends only on other layers in the set above.
    L never depends on any adapter or external system.
∀ adapter A ∈ UCA:
    A depends on some layer L ∈ {USR}.
    No layer L depends on A.

D4 is not a policy — it is a structural property of the derivation graph. Violating D4 would create a cycle or an upward dependency, both of which are already forbidden by D1 and D2.

Section 8: Conformance Criteria

8.1 UCA Conformance Tests

An implementation conforms to the UCA Formal Specification if and only if:

8.2 Conformance Levels

Section 9: Relationship to the Existing Stack

9.1 How UCA Connects to Part V (Standards Alignment)

Part V of the Kernel defines the advisory alignment between constitutional concepts and W3C external standards. UCA formalizes this relationship:

9.2 How UCA Connects to USR/CoreFab

USR/CoreFab executes constitutional operations. UCA is what allows those operations to interact with the world:

USR/CoreFab                    UCA                     External World
─────────────                  ─────                   ──────────────
┌───────────┐                  ┌─────────┐             ┌──────────┐
│ Execute   │ ──serialize──→  │ JSON-LD │ ──HTTP──→   │ Web API  │
│ Attest    │ ──identity──→   │ DNS     │ ──resolve→  │ DNS      │
│ Store     │ ──persist──→    │ Syncth. │ ──sync──→   │ Peers    │
│ Verify    │ ──hash──→       │ IPFS    │ ──pin──→    │ Network  │
└───────────┘                  └─────────┘             └──────────┘

USR/CoreFab never knows which specific adapter is in use. It knows only the constitutional contract (serialize, resolve, persist). UCA maps those contracts to concrete adapters at runtime.

9.3 How UCA Connects to UCD

UCD (Universal Constitutional Derivatives) composes building blocks from UCA capabilities:

UCA → specific adapter capabilities → UCD → composed derivatives

UCD does not re-derive from the kernel (D5). It composes from what UCA makes available. If UCA provides a naming adapter, UCD can compose an identity verification derivative. If UCA provides a storage adapter, UCD can compose a persistence derivative.
