## 1. Ontological Chambers & Core Entities

### Chamber I: Strategy & Motivation
- **Strategic Objective**: Qualitative directional target defined by leadership.
- **Initiative**: Strategic portfolio investment vehicle funding transformation projects.
- **KPI**: Quantifiable health or progress measurement.

### Chamber II: Business Architecture & Process
- **Capability (Level 1-3)**: Foundational building block defining *what* the business does.
- **Value Stream**: End-to-end customer or patient journey mapping value-adding stages.
- **Process**: Structured operational flow realizing a capability.
- **Workflow**: Automated DAG execution of tasks and gateways (clean-room BPMN).

### Chamber III: Application & Integration
- **Application**: Deployable software system or SaaS tool (HubSpot, Salesforce, Apex Core).
- **Service**: Independently deployable microservice or function.
- **API**: Formalized contract (REST, GraphQL, gRPC, SSE).
- **DataObject**: Structured information entity (e.g., Patient Record, Claim Determination).

### Chamber IV: AI Infrastructure & Telemetry
- **AI Model**: Foundation or fine-tuned model (Claude 3.7 Sonnet, GPT-4o) with pricing metrics.
- **AI Agent**: Autonomous reasoning agent with assigned autonomy level and capabilities.
- **MCP Server**: Model Context Protocol gateway exposing resources, prompts, and tools.
- **Lethal Trifecta Sentinel**: Active detection rule for agents with:
  [Private Data Access] + [Untrusted Content Ingestion] + [External Communication].

### Chamber V: Architecture Governance
- **Architecture Decision Record (ADR)**: Governed rationale, trade-offs, and consequences.
- **Architecture Review Board (ARB)**: Multi-stage review pipeline (Intake, Security, ARB, Ratified).
- **Risk**: Operational or compliance hazard mapped to controls.

### Chamber VI: Financial Intelligence
- **Direct Software TCO**: Licensing, infrastructure hosting, maintenance, and support.
- **Live AI Run-Rate**: Real-time token burn computed from prompt and completion volume.
- **Capability Spend Allocation**: Downstream software cost attribution per business capability.
