feat(canon): add Orthogonal Architecture Standard v1.0 and schema v1.0.1

OAS defines a multidimensional architecture model for compute systems: - 6 canonical dimensions: Stack, Logic, Plane, Quality, Capability, Intelligence - VSM (Viable System Model) tagging throughout - Canonical element types and 9 relation types - Intelligence dimension I1-I5 with governance constraint: I5 agents MUST operate through the control plane (P3 — directly governs Custodian design) Schema provides two-layer validation: - Layer 1: JSON Schema 2020-12 structural validation - Layer 2: semantic rule profile R1-R16 (placement, governance, intelligence coupling, relation typing rules) + YAML machine-readable rule block - Draft and production validation profiles Terminology and dimensions will guide state-hub and Custodian implementation.

+*A framework for compute systems design*
+
+# Orthogonal Architecture Standard (OAS)
+
+### Format Specification
+
+**Version:** 1.0
+**Status:** Draft Standard
+**Scope:** Cloud-native compute systems and Kubernetes platforms
+
+---
+
+# 1. Introduction
+
+*(VSM System 5 — Identity and Policy)*
+
+The Orthogonal Architecture Standard (OAS) defines a **structured format for describing modern compute systems** using a multidimensional architecture model.
+
+The standard establishes:
+
+* a consistent architecture vocabulary
+* a canonical set of architectural dimensions
+* a modeling format for systems, services, and capabilities
+* relationships between architecture components
+
+The goal is to enable **consistent architecture descriptions across teams and organizations**.
+
+The standard is especially suited for:
+
+* Kubernetes-based platforms
+* internal developer platforms
+* SaaS architectures
+* distributed systems
+* AI-integrated platforms
+
+---
+
+# 2. Normative Principles
+
+*(VSM System 5 — Identity and Policy)*
+
+The Orthogonal Architecture Standard is based on the following normative principles.
+
+### P1 Separation of Dimensions
+
+Architecture descriptions MUST separate independent perspectives into **orthogonal dimensions**.
+
+### P2 Stable Capability Core
+
+Capabilities represent **stable system intent** and MUST be distinguished from implementation.
+
+### P3 Control Plane Governance
+
+All configuration and operational changes MUST occur through a **control plane**.
+
+Automation and AI MUST NOT bypass governance mechanisms.
+
+### P4 Cross-Cutting Quality Constraints
+
+Quality properties apply across all architecture layers and MUST NOT be modeled as stack layers.
+
+### P5 Explicit Relationships
+
+Architecture elements MUST declare explicit relations with other elements.
+
+---
+
+# 3. Architecture Meta-Model
+
+*(VSM System 3 — Internal Control)*
+
+The meta-model defines the structural components used in architecture descriptions.
+
+---
+
+## 3.1 Architecture
+
+An **Architecture** describes a system through:
+
+* Dimensions
+* Levels
+* Elements
+* Relations
+* Quality constraints
+
+---
+
+## 3.2 Dimension
+
+A **Dimension** is a classification axis used to analyze architecture.
+
+Each dimension contains **levels**.
+
+---
+
+## 3.3 Level
+
+A **Level** represents an ordered stratum within a dimension.
+
+Example:
+
+```
+Infrastructure → Runtime → Platform Services → Applications
+```
+
+---
+
+## 3.4 Element
+
+An **Element** is a concrete architectural component.
+
+Examples:
+
+* Service
+* API
+* Database
+* Workflow engine
+* Policy engine
+* AI component
+
+---
+
+## 3.5 Relation
+
+A **Relation** describes how two elements interact.
+
+Example relation types:
+
+* realizes
+* depends_on
+* composes
+* governs
+* observes
+* exposes
+
+---
+
+# 4. Canonical Architecture Dimensions
+
+*(VSM System 1 — Operational Units)*
+
+The Orthogonal Architecture Standard defines **six canonical dimensions**.
+
+| Dimension    | Purpose                               |
+| ------------ | ------------------------------------- |
+| Stack        | technical hosting substrate           |
+| Logic        | functional decomposition              |
+| Plane        | operational responsibility            |
+| Quality      | cross-cutting architecture properties |
+| Capability   | stable capability modeling            |
+| Intelligence | degree of intelligent automation      |

+Each architecture description MUST use these dimensions.

+
+# Appendix A — VSM Perspective on Kubernetes
+
+*(Cybernetic Architecture Interpretation)*
+
+Kubernetes can be interpreted as a **cybernetic control system**.
+
+Mapping Kubernetes components to VSM:
+
+| VSM System | Kubernetes Equivalent             |
+| ---------- | --------------------------------- |
+| System 1   | application pods                  |
+| System 2   | scheduler, networking             |
+| System 3   | controllers, reconciliation loops |
+| System 3*  | monitoring and observability      |
+| System 4   | autoscaling and adaptive systems  |
+| System 5   | governance and policy frameworks  |
+
+---
+
+## Cybernetic Loop
+
+Kubernetes continuously performs:
+
+```
+observe → compare → reconcile
+```
+
+This implements Beer’s cybernetic control loop.
+
+---
+
+## Viability Principle
+
+The system maintains stability by balancing:
+
+* operational workloads
+* coordination mechanisms
+* governance policies
+* adaptive intelligence
+
+---
+
+## Recursion
+
+Each subsystem can itself be a viable system.
+
+Examples:
+
+* a microservice architecture
+* a Kubernetes cluster
+* a developer platform
+
+Each level can contain its own:
+
+* operations
+* coordination
+* governance
+* intelligence
+
+---
+
+# Appendix B — Sources and Influences
+
+Orthogonal Architecture integrates ideas from:
+
+* Stafford Beer — Viable System Model
+* Viable System Model
+* Kubernetes architecture documentation
+* cloud architecture frameworks
+* platform engineering practices
+* capability-centric architecture approaches
+
+Influential work includes:
+
+* *Platform Strategy* — Gregor Hohpe
+* Kubernetes architecture documentation
+* cloud architecture frameworks (Google Cloud, AWS)
+* Domain-Driven Design
+
+---
+
+# Summary
+
+The Orthogonal Architecture Standard provides a **formal modeling specification** integrating:
+
+* platform engineering
+* cloud architecture
+* capability modeling
+* cybernetic governance
+* AI integration
+
+Using VSM tagging ensures that architectures remain **viable, adaptive, and governable systems**.
