Universal Constitutional Experience System — UIX v0.1.1

A constitutional doctrine of experience: how intelligence, humans, systems, and reality interact under constitutional principles — the layer where constitutional intelligence becomes perceivable, usable, and governable.

Part I — Specification

1. Position in the constitutional chain

Reality
  → USCP (six primitives — what must always be true)
  → USC / URS (representation)
  → USE (Universal Selection Engine — verify → select → execute)
  → UIX (this layer — where constitutional intelligence becomes
     perceivable, usable, and governable)
  → Applications

UIX sits below USE and above Applications: every experience is the result of a selection (USE-2: selection precedes execution). UIX is not a component library, a design system, or a framework — it is the constitutional experience layer. Motion, analytics, dashboards, spatial and multimodal interfaces are capabilities, never the identity.

2. Strategic principle

**How should intelligence, humans, systems, and reality interact under constitutional principles?**

3. Layer architecture

Layer	Role	Technology
Selection	USE — verified options, declared preference, recorded selection	USE log · USE-1..6
Truth	Constitutional models, verification, identity, invariants	Rust → WASM
Performance	Rendering, layout, graphics, animation, computation	Zig → WASM (on demand)
Experience	Browser integration, PWA lifecycle, adapters, interaction	JavaScript (orchestrates, never owns logic)

Technologies serve the architecture; all three implementation layers are replaceable below the invariant layer (UAM doctrine: capabilities are adapters, never core dependencies).

4. Invariants

UIX-1 — Constitution first. An experience node must conform to applicable governance rules before any pixel is rendered (UIX-GOV-001..012 enforced in-browser via WASM).
UIX-2 — Semantics over syntax. `SemanticIntent` — what an element means — replaces component hierarchies; rendering is a downstream concern.
UIX-3 — Governance before generation. Rules constrain what can be built before it exists; violations are impossible to render, not merely discouraged.
UIX-4 — Trust seals mandatory. Every delivered node carries a content-addressed `TrustSeal` (SHA-256, nonce-protected) proving compliance; no seal, no delivery.
UIX-5 — Constitutional selection (USE alignment). Every render is selected from verified options by declared preference (USE-1..6); the USE log records every selection before execution, and the system does nothing when no verified option exists.
UIX-6 — External usability. UIX is constitutional by design but not captive: any external entity or platform may use it via a declared interoperability profile (CCA §4) — capabilities are optional, invariants apply in full for ICore adoption, and external platforms may adopt capabilities with a declared profile. Superset over replacement.

5. LD-family fit (how the Linked Data family composes with UIX)

LD document	Role in UIX	Evidence in the layer
CORE-LD	Semantic representation basis — every `SemanticIntent` and node payload is CORE-LD-shaped	Experience nodes serialize to JSON/CBOR-LD; bridge uses JSON bridge until CBOR-LD lands
TRUST-LD	Identity + provenance of experience sources — trust seals attest who/what produced an experience	`TrustSeal::new(node_id, rules, nonce)` — content-addressed proof of governance provenance
POLICY-LD	Governance — which experiences may exist, in which modes, under which constraints	UIX-GOV rules, `GovernanceEngine::default_rules()`, `verify_node`/`verify_graph`
MEMORY-LD	Audit — the USE log and verification history as an append-only constitutional record	USE log (`useLog`), Lamport-timestamped `ConstitutionalResponse`, seal history

The experience pipeline maps directly onto the family: input → CORE-LD, governance → POLICY-LD, provenance → TRUST-LD, audit → MEMORY-LD, with USE as the selection act between verification and execution.

6. Four-question stress test

Question	Answer
What must always be true?	Every experience conforms before it renders (UIX-1..5)
What should every conforming system look like?	Four-layer architecture: Selection / Truth / Performance / Experience
How do systems interact?	Typed boundary: `ExperienceEvent` (observations) → `ConstitutionalCommand` (verified instructions) → `RenderFrame` (feedback loop)
How do we prove conformance?	In-browser WASM verification, TrustSeals, USE log, UIX conformance suite

Part II — Doctrine

Selection is the act; experience is the consequence

UIX embodies the USE boundary: certainty above the Selection rung (constitutional rules are fixed, non-negotiable, machine-verified) and adaptability below it (engines, modes, and renderers are replaceable and selected per situation). The USE log makes every choice visible, reversible, and auditable — no hidden fallbacks, no implicit decisions.

Constitutional by design, usable by anyone

UIX never requires the whole of ICore. External platforms may adopt UIX capabilities under a declared interoperability profile; ICore adoption carries the full invariant set. This is the doctrine of superset over replacement applied to experience: a strict constitutional core, tolerant adoption paths, no lock-in.

Freeze gate

UIX remains Doctrine until (1) a UIX conformance suite runs green (native 36+ tests + in-browser WASM verification), and (2) the USE log is demonstrated end-to-end in the CodeLab (verify → select → execute across TRUST-LD → USE → POLICY-LD → MEMORY-LD). Only then does UIX flip to Frozen and enter UCF attestation. The first external adoption may, at that point, register as the first interop-profile case.
